Question 1Introduction to Apparel Industry and Career Opportunities

In the apparel production chain, which stage immediately follows fabric inspection and spreading before stitching begins?

  1. Cutting Correct answer.
  2. Embroidery finishing
  3. Dyeing
  4. Retailing

Explanation

Cutting is the stage where spread fabric layers are sliced into garment panels according to the marker, and it comes directly before sewing. Dyeing happens at the fabric stage, and retailing occurs after the finished garment is packed.

Question 2Introduction to Apparel Industry and Career Opportunities

A student wants a career that designs the layout of pattern pieces on fabric to minimise waste. Which job role matches this description?

  1. Fashion photographer
  2. Quality auditor
  3. Marker maker Correct answer.
  4. Merchandiser

Explanation

A marker maker arranges pattern pieces efficiently on the fabric to reduce cutting waste, which directly matches the described task. Merchandisers coordinate orders and timelines, auditors check conformity, and photographers produce images.

Question 3Introduction to Apparel Industry and Career Opportunities

Which term describes the organised sequence of operations from fibre through yarn, fabric, garment and finally to the consumer?

  1. Garment drape
  2. Colour fastness
  3. Stitch density
  4. Apparel supply chain Correct answer.

Explanation

The apparel supply chain is the connected sequence of fibre, yarn, fabric, garment manufacturing, distribution and retail that brings a product to the consumer. The other options are technical properties or measures of materials and seams.

Question 4Introduction to Apparel Industry and Career Opportunities

In apparel manufacturing, what does the abbreviation SAM most commonly represent in production planning?

  1. Seam allowance margin
  2. Stitch accuracy measurement
  3. Sample approval method
  4. Standard allowed minute Correct answer.

Explanation

SAM stands for standard allowed minute, the time benchmark used to plan capacity, cost and operator targets. It is a time value, not an approval procedure, a seam allowance or an accuracy measure.

Question 5Introduction to Apparel Industry and Career Opportunities

Which department in a garment factory is mainly responsible for ensuring that finished garments meet the buyer's measurement and construction requirements before shipment?

  1. Human resources
  2. Industrial engineering
  3. Quality assurance Correct answer.
  4. Product development

Explanation

Quality assurance inspects and tests finished goods against buyer specifications such as measurements, construction and workmanship before shipment. Product development creates samples, industrial engineering sets methods and times, and human resources manages staffing.

Question 6Introduction to Apparel Industry and Career Opportunities

A factory receives an order for 12,000 shirts and must plan line capacity. Which information is most directly needed to estimate the sewing labour minutes required?

  1. Number of retail stores in the region
  2. Fabric width and shade band
  3. SAM per operation and total order quantity Correct answer.
  4. Buyer's brand logo colour

Explanation

Multiplying the standard allowed minutes per operation by the order quantity gives the total sewing minutes needed for capacity planning. Fabric width, logo colour and store count do not determine sewing labour time.

Question 7Introduction to Apparel Industry and Career Opportunities

A merchandiser is costing a knit top. Which cost element belongs to direct material cost rather than overhead?

  1. Salary of the security staff
  2. Factory electricity for the sewing floor
  3. Depreciation of the cutting table
  4. Body fabric consumed per garment Correct answer.

Explanation

Direct material cost covers materials that become part of the product, such as body fabric consumed per garment. Electricity, security salaries and equipment depreciation are indirect costs spread across production as overhead.

Question 8Introduction to Apparel Industry and Career Opportunities

A pattern technologist increases seam allowance from 1 cm to 1.5 cm on a curved armhole. What is the most likely practical consequence during sewing?

  1. More fabric must be trimmed or clipped to keep the curve flat Correct answer.
  2. The fabric consumption per garment will fall
  3. The garment will automatically become one size larger
  4. The stitch type must change from lockstitch to overlock

Explanation

Extra allowance on a curved seam creates bulk that must be clipped or trimmed so the curve lies flat when turned. The finished garment size is set by the seam line, not the allowance, so consumption rises rather than falls and the stitch type need not change.

Question 9Introduction to Apparel Industry and Career Opportunities

During fabric inspection, a roll shows a cluster of broken yarns running in the warp direction over several metres. Which defect category does this describe?

  1. Shade variation
  2. Warp-way defect Correct answer.
  3. Off-grain print
  4. Weft-way defect

Explanation

Defects aligned with the lengthwise warp yarns, such as sustained broken warp ends, are classified as warp-way defects. Weft-way defects run across the width, shade variation concerns colour, and print alignment is a separate printing issue.

Question 10Introduction to Apparel Industry and Career Opportunities

A buyer requests a lower unit price. Which action by the merchandiser most directly reduces labour cost per garment without changing design?

  1. Balancing the line to reduce operator idle time Correct answer.
  2. Adding an extra inspection stage
  3. Switching to a more expensive lining fabric
  4. Increasing the number of sample submissions

Explanation

Line balancing distributes work evenly so operators are not waiting, which lowers effective labour minutes per garment. Costlier lining raises material cost, extra samples add development cost, and additional inspection adds overhead.

Question 11Introduction to Apparel Industry and Career Opportunities

Which career path in the apparel industry focuses on predicting colour, silhouette and fabric trends and translating them into seasonal ranges?

  1. Industrial engineering
  2. Fashion forecasting and design Correct answer.
  3. Logistics coordination
  4. Garment washing technology

Explanation

Fashion forecasting and design roles study trend information and convert it into seasonal colour palettes, silhouettes and product ranges. Industrial engineering, logistics and washing technology address methods, movement and wet processing respectively.

Question 12Introduction to Apparel Industry and Career Opportunities

A factory must choose between a lockstitch and a 5-thread overlock for joining and neatening a side seam on woven denim. Which reasoning is most sound?

  1. The overlock produces a straight, inelastic seam unsuitable for any woven fabric
  2. Both stitches are identical in strength and appearance
  3. The overlock joins and neatens in one pass, but lockstitch offers a stronger, less bulky seam for high-stress areas Correct answer.
  4. The lockstitch automatically neatens raw edges while joining

Explanation

A 5-thread overlock combines joining with edge neatening in one operation but adds bulk, while a lockstitch gives a strong, flat seam often preferred in high-stress areas. The two stitches differ in strength, bulk and elasticity, so they are not interchangeable without trade-offs.

Question 13Introduction to Apparel Industry and Career Opportunities

Which document issued by the buyer authorises a supplier to begin bulk production after sample approval?

  1. Production purchase order Correct answer.
  2. Commercial invoice
  3. Packing list
  4. Bill of lading

Explanation

A purchase order confirms the buyer's commitment and authorises the supplier to start bulk production once samples are approved. The bill of lading, packing list and commercial invoice are shipping and payment documents generated later.

Question 14Introduction to Apparel Industry and Career Opportunities

A knit T-shirt line shows a bottleneck at the sleeve attaching operation, where work-in-progress piles up while downstream operators wait. Which action best addresses the root cause?

  1. Redistribute work elements from the bottleneck operation to adjacent operators with spare capacity Correct answer.
  2. Raise the selling price of the T-shirt
  3. Add more final inspection staff
  4. Increase the cutting quantity per day

Explanation

A bottleneck arises when one operation takes longer than the takt time, so shifting work elements to operators with idle capacity balances the line and relieves the pile-up. Inspection, cutting volume and pricing do not change the operation's cycle time.

Question 15Introduction to Apparel Industry and Career Opportunities

A supplier's fabric shows acceptable colour under factory lighting but appears noticeably different under daylight at the buyer's office. Which concept explains this and what is the appropriate control?

  1. Bow distortion; stretch the fabric before approval
  2. Shrinkage; wash the fabric before approval
  3. Metamerism; approve colour under a standardised light source agreed with the buyer Correct answer.
  4. Pilling; abrade the surface before approval

Explanation

Metamerism occurs when a colour match appears different under different light sources, so approval must use a standardised illuminant agreed with the buyer. Shrinkage, pilling and bow distortion are unrelated physical or dimensional issues.

Question 16Introduction to Apparel Industry and Career Opportunities

A merchandiser compares two factories: Factory A has a lower quoted FOB price but a historical 8% rejection rate, while Factory B quotes 6% higher with a 2% rejection rate. Which analysis best supports the sourcing decision?

  1. Choose Factory B because a higher quote guarantees better quality
  2. Ignore rejection rates because they affect only the buyer's brand image
  3. Compare total landed cost including rework, replacement and delay risk, not quoted price alone Correct answer.
  4. Choose Factory A because the quoted FOB price is always the decisive factor

Explanation

Quoted FOB price excludes the cost of rejects, rework, replacement shipments and delay penalties, so total landed cost gives a fairer comparison. A higher quote does not guarantee quality, and rejection rates directly affect cost as well as brand image.

Question 17Fibres and Yarns: Types, Properties and Identification

Which natural fibre is obtained from the seed hair of a plant and is composed mainly of cellulose?

  1. Cotton Correct answer.
  2. Wool
  3. Silk
  4. Jute

Explanation

Cotton is a cellulosic seed fibre harvested from the boll of the cotton plant. Wool and silk are protein fibres of animal origin, while jute is a bast fibre from the plant stem.

Question 18Fibres and Yarns: Types, Properties and Identification

A fabric sample burns with a smell of burning hair and leaves a crushable black ash. Which fibre is most likely present?

  1. Wool Correct answer.
  2. Polyester
  3. Viscose
  4. Cotton

Explanation

Protein fibres such as wool contain nitrogen and sulphur, so they smell of burning hair or feathers and leave a crushable dark ash. Cellulosic and synthetic fibres do not give this smell.

Question 19Fibres and Yarns: Types, Properties and Identification

Which term describes the natural length of a fibre as it grows, before any cutting?

  1. Staple length Correct answer.
  2. Twist level
  3. Crimp
  4. Denier

Explanation

Staple length is the measured length of a natural fibre in its grown state, and it strongly affects yarn quality. Denier measures linear density, twist is a spinning variable and crimp describes waviness.

Question 20Fibres and Yarns: Types, Properties and Identification

Which fibre is produced as a continuous filament directly by the silkworm?

  1. Flax
  2. Silk Correct answer.
  3. Cotton
  4. Angora

Explanation

The silkworm extrudes a continuous filament that forms the cocoon, so silk is naturally a filament fibre. Cotton, flax and angora are all staple fibres of limited length.

Question 21Fibres and Yarns: Types, Properties and Identification

Which manufactured fibre is regenerated from a natural polymer rather than synthesised from petrochemical monomers?

  1. Viscose Correct answer.
  2. Acrylic
  3. Polypropylene
  4. Nylon

Explanation

Viscose is regenerated cellulose, made by dissolving and reforming a natural polymer. Nylon, acrylic and polypropylene are fully synthetic polymers built from chemical monomers.

Question 22Fibres and Yarns: Types, Properties and Identification

Which property of a fibre is most directly responsible for its ability to absorb moisture from the air?

  1. Crimp
  2. Hydrophilicity Correct answer.
  3. Tenacity
  4. Elastic recovery

Explanation

Hydrophilic fibres carry polar groups that attract and hold water molecules, giving them moisture regain. Crimp, tenacity and elastic recovery describe shape, strength and stretch behaviour instead.

Question 23Fibres and Yarns: Types, Properties and Identification

A yarn is described as 100% cotton but the care label warns that it stretches easily and dries very quickly. Which fibre blend component would best explain this behaviour?

  1. A small addition of wool
  2. A small addition of viscose
  3. A small addition of elastane Correct answer.
  4. A small addition of linen

Explanation

Elastane is an elastomeric fibre that gives high stretch and rapid drying even in small percentages. Linen, viscose and wool would not deliver that elastic stretch.

Question 24Fibres and Yarns: Types, Properties and Identification

In the yarn count system denier, what does a higher number indicate?

  1. A finer yarn
  2. A tighter twist
  3. A coarser yarn Correct answer.
  4. A longer staple

Explanation

Denier is the mass in grams of 9000 metres of yarn, so a larger denier means a heavier, coarser yarn. Finer yarns carry lower denier values.

Question 25Fibres and Yarns: Types, Properties and Identification

Which spinning method produces a yarn by wrapping fibres around a continuous filament core?

  1. Core spinning Correct answer.
  2. Ring spinning
  3. Open-end spinning
  4. Worsted spinning

Explanation

Core spinning feeds a filament core through the drafting zone so staple fibres wrap around it, giving strength plus surface softness. Ring, open-end and worsted spinning build yarn from staple fibres without a core.

Question 26Fibres and Yarns: Types, Properties and Identification

Which yarn structure would give a fabric the greatest bulk, warmth and softness with low twist?

  1. A high-twist crepe yarn
  2. A tightly twisted two-ply yarn
  3. A monofilament yarn
  4. A low-twist woollen spun yarn Correct answer.

Explanation

Woollen spun yarns use shorter fibres with low twist, trapping air for bulk, warmth and softness. High twist, plied and monofilament structures are denser or smoother.

Question 27Fibres and Yarns: Types, Properties and Identification

A buyer needs a fibre with high tenacity, low moisture regain and excellent resistance to sunlight for outdoor ropes. Which fibre best fits?

  1. Cotton
  2. Wool
  3. Polyester Correct answer.
  4. Viscose

Explanation

Polyester combines high strength, low moisture regain and good sunlight resistance, making it suitable for outdoor ropes. Wool, viscose and cotton are weaker when wet or degrade faster in sunlight.

Question 28Fibres and Yarns: Types, Properties and Identification

Which test would most reliably distinguish a cellulosic fibre from a protein fibre in a laboratory?

  1. Checking the yarn twist direction
  2. Counting the plies in the yarn
  3. Burning a sample and noting the odour Correct answer.
  4. Measuring staple length

Explanation

Burning reveals the characteristic odour: burning paper for cellulose and burning hair for protein. Length, twist direction and ply count say nothing about chemical composition.

Question 29Fibres and Yarns: Types, Properties and Identification

Why is combing used in the production of fine cotton and worsted yarns?

  1. To add moisture to the fibres
  2. To increase fibre crimp
  3. To remove short fibres and align long ones Correct answer.
  4. To set the twist permanently

Explanation

Combing removes short fibres and neps and parallelises the long fibres, producing a smoother, stronger yarn. It does not add crimp, moisture or set twist.

Question 30Fibres and Yarns: Types, Properties and Identification

A fabric label states a yarn is 2/60 Nm. What does this notation indicate?

  1. A two-ply yarn where each ply is 60 Nm Correct answer.
  2. A single yarn of 60 Nm
  3. A yarn with 60 twists per metre
  4. A yarn of 2 denier and 60 filaments

Explanation

In the metric count notation, the number before the slash gives the ply count and the number after gives the count of each single yarn. So 2/60 Nm means two plies each of 60 Nm.

Question 31Fibres and Yarns: Types, Properties and Identification

Which characteristic most clearly separates filament yarns from staple yarns in a woven fabric's surface?

  1. Filament yarns always give a hairy, fibrous surface
  2. Staple yarns cannot be dyed
  3. Staple yarns are always stronger
  4. Filament yarns usually give a smoother, more uniform surface Correct answer.

Explanation

Filament yarns consist of long continuous strands, so they produce smooth, uniform surfaces with little protruding fibre. Staple yarns have fibre ends that create a softer, slightly hairy surface.

Question 32Fibres and Yarns: Types, Properties and Identification

Which fibre property explains why wool garments feel warm even when slightly damp?

  1. Its smooth filament surface
  2. Its low elongation at break
  3. Its high initial modulus
  4. Its natural crimp and moisture regain Correct answer.

Explanation

Wool's crimp traps insulating air while its high moisture regain allows it to absorb moisture without feeling cold and wet. High modulus and low elongation would make it stiff, not warm.

Question 33Fibres and Yarns: Types, Properties and Identification

A dyer finds that a 100% polyester fabric takes up disperse dye only at high temperature under pressure, while a cotton fabric dyes readily with reactive dyes at lower temperature. Which fibre characteristic best explains this difference?

  1. Polyester has a much higher moisture regain than cotton
  2. Polyester's crystalline, hydrophobic structure limits dye penetration Correct answer.
  3. Cotton has a higher degree of polymerisation than polyester
  4. Cotton's filament structure blocks dye uptake

Explanation

Polyester is highly crystalline and hydrophobic, so dye molecules diffuse slowly and require heat and pressure to open the structure. Cotton is hydrophilic with accessible amorphous regions, allowing reactive dye uptake at lower temperatures.

Question 34Fibres and Yarns: Types, Properties and Identification

An analyst examines two yarns of equal linear density. Yarn A has a twist multiplier well above the normal range for its count, while Yarn B is within range. What is the most likely consequence for Yarn A?

  1. Lower strength and a lively, kinky handle Correct answer.
  2. Greater staple length
  3. Increased moisture regain
  4. Higher strength with improved softness

Explanation

Excessive twist causes fibres to spiral steeply, reducing strength and producing snarling, kinky yarn with a harsh handle. Moderate twist within the normal multiplier range gives optimum strength.

Question 35Fibres and Yarns: Types, Properties and Identification

A blend of 65% polyester and 35% cotton is spun into a yarn. Which statement best explains why such blends are commonly used in workwear?

  1. Polyester contributes strength and crease recovery while cotton contributes absorbency and comfort Correct answer.
  2. Both fibres are protein fibres with similar properties
  3. Cotton contributes strength while polyester contributes warmth
  4. Polyester contributes absorbency while cotton contributes crease recovery

Explanation

In a poly-cotton blend, polyester adds tensile strength, durability and crease recovery, while cotton adds moisture absorbency and next-to-skin comfort. The complementary properties give durable, comfortable workwear.

Question 36Fibres and Yarns: Types, Properties and Identification

Two cotton yarns have the same linear density, but one is made from combed long-staple cotton and the other from carded short-staple cotton. Which outcome is most consistent with fibre science?

  1. The carded yarn will have higher tenacity due to more fibre ends
  2. The carded yarn will be smoother because short fibres pack tightly
  3. The combed yarn will be smoother and stronger with fewer thin places Correct answer.
  4. Both yarns will have identical evenness

Explanation

Longer, combed fibres align better and contain fewer short fibres, so the yarn is more even, smoother and stronger with fewer thin places. Short fibres in carded yarn create more protruding ends and irregularity.

Question 37Fabric Construction, Weaves and Fabric Finishes

Which weave structure is characterised by a stepwise diagonal line formed where warp and weft floats progress by one thread each pick?

  1. Pile weave
  2. Twill weave Correct answer.
  3. Satin weave
  4. Plain weave

Explanation

In a twill weave the interlacing points shift by one warp thread on each successive pick, producing a continuous diagonal rib across the cloth. This float progression also gives twill its characteristic drape and softness compared with a simple over-one-under-one structure.

Question 38Fabric Construction, Weaves and Fabric Finishes

A fabric is described as having a 2/2 twill. What does this notation indicate about the weave repeat?

  1. Two picks are inserted per shed in a double-cloth construction
  2. Two colours alternate in both warp and weft stripes
  3. Two warp yarns float over two weft yarns before interlacing Correct answer.
  4. Two pile yarns are bound per ground pick

Explanation

Twill notation counts the number of warp ends lifted over the number of picks before the interlacing reverses, so 2/2 means a float over two threads then under two. The face of such a cloth shows a balanced diagonal with equal warp and weft coverage.

Question 39Fabric Construction, Weaves and Fabric Finishes

Which characteristic is typical of a plain-weave cotton poplin compared with a plain-weave voile of the same fibre?

  1. Much longer floats producing a glossy face
  2. Higher warp density giving a crisper, smoother surface Correct answer.
  3. Loops of yarn projecting from the surface
  4. A pronounced diagonal rib across the width

Explanation

Poplin is woven with a fine warp at high sett against a relatively coarser weft, which creates a dense, smooth, slightly ribbed-across appearance and a crisp handle. Voile uses lower sett and higher twist yarns, making it more open and sheer.

Question 40Fabric Construction, Weaves and Fabric Finishes

In a warp-knitted fabric, how are the yarns principally arranged?

  1. Loops are formed from a single weft yarn traversing the width
  2. Loops run along the length of the fabric formed from warp beams Correct answer.
  3. Yarns interlace at right angles without looping
  4. Staple fibres are bonded by chemical adhesive only

Explanation

Warp knitting feeds many parallel yarns from a warp beam, and each needle loops its own yarn so the wales run vertically along the fabric length. This gives high productivity and low extensibility compared with weft knitting.

Question 41Fabric Construction, Weaves and Fabric Finishes

Which property best explains why a single-jersey weft-knitted fabric curls at the selvedges?

  1. Unbalanced loop structure creates internal stresses released at the edges Correct answer.
  2. The fabric has been calendered on one face only
  3. The fabric contains an equal number of face and back loops
  4. Warp yarns are under higher tension than weft yarns

Explanation

Single jersey has all loops drawn to one face, so the front and back of the structure are not identical and the stored bending energy in the loops makes the edges roll. Balancing the structure, as in rib or interlock, reduces this curling.

Question 42Fabric Construction, Weaves and Fabric Finishes

Which nonwoven bonding method uses high-pressure water jets to entangle a fibre web?

  1. Thermal calendering
  2. Needle punching
  3. Spunlacing Correct answer.
  4. Chemical saturation

Explanation

Spunlacing, also called hydroentanglement, directs fine high-pressure water jets at the web so fibres interlock mechanically without binder or heat. The result is a soft, drapeable fabric widely used in wipes and medical textiles.

Question 43Fabric Construction, Weaves and Fabric Finishes

A finisher applies a caustic soda treatment under tension to a cotton fabric to increase lustre and strength. Which finish is being described?

  1. Mercerisation Correct answer.
  2. Schreinerising
  3. Sanforisation
  4. Calendering

Explanation

Mercerisation swells the cotton fibre in sodium hydroxide while tension is maintained, causing the cellulose to reorient, which raises lustre, dye uptake and tensile strength. Removing the tension during the same treatment instead yields a crepe or stretch effect.

Question 44Fabric Construction, Weaves and Fabric Finishes

Which finish is applied specifically to wool fabrics to reduce felting shrinkage during laundering?

  1. Enzyme bio-polishing
  2. Antifelting resin treatment Correct answer.
  3. Soil-release finishing
  4. Flame-retardant finishing

Explanation

Antifelting finishes, such as oxidative or resin treatments, modify or mask the wool scale structure so the fibres cannot ratchet past each other and felt. This allows wool garments to be machine washed with limited shrinkage.

Question 45Fabric Construction, Weaves and Fabric Finishes

What is the primary purpose of sanforisation in cotton fabric production?

  1. To impart a permanent pleat to the fabric
  2. To remove natural waxes before dyeing
  3. To increase the fabric's resistance to burning
  4. To control residual shrinkage by mechanical compressive shrinking Correct answer.

Explanation

Sanforisation uses a rubber belt or blanket to compress the fabric lengthwise while it is damp, forcing the yarns closer together so that subsequent washing produces minimal further shrinkage. It is a mechanical process and adds no chemical finish.

Question 46Fabric Construction, Weaves and Fabric Finishes

A fabric is given a resin finish that cross-links cellulose chains. Which performance change should the finisher expect?

  1. Improved crease recovery with some loss of tear strength Correct answer.
  2. Increased elongation with improved softness
  3. Higher moisture regain with reduced dimensional stability
  4. Greater flammability with reduced colour fastness

Explanation

Cross-linking resins restrict the sliding of cellulose chains, so the fabric recovers from creasing, but the same restriction lowers extensibility and tear strength. This trade-off is why durable-press finishes must be carefully controlled.

Question 47Fabric Construction, Weaves and Fabric Finishes

Which weave would produce a fabric with the smoothest, most lustrous face and the greatest tendency to snag?

  1. Plain weave
  2. Satin weave Correct answer.
  3. Mock leno weave
  4. Rib weave

Explanation

Satin weave carries long floats of warp or weft over many threads before interlacing, so light reflects from an almost unbroken surface to give high lustre. The same long floats are easily caught and pulled, making the fabric prone to snagging.

Question 48Fabric Construction, Weaves and Fabric Finishes

In a dobby loom, which mechanism controls the shedding action?

  1. A cam or tappet stack fixed to the crankshaft
  2. A friction-driven weft accumulator
  3. A pattern chain or pegged lattice selecting a limited number of harnesses Correct answer.
  4. A Jacquard punched card controlling each individual end

Explanation

Dobby shedding uses a chain, pegs or electronic selection to raise a small set of harnesses in sequence, allowing small geometric motifs and textured weaves. It sits between simple cam shedding and full Jacquard capability.

Question 49Fabric Construction, Weaves and Fabric Finishes

Which defect appears as a thick, slack place in the warp direction caused by a broken end that has been repaired poorly?

  1. A hangy or slack end Correct answer.
  2. A temple mark
  3. A weft crack
  4. A shuttle mark

Explanation

A hangy occurs when a broken warp end is pieced back with insufficient tension or an oversized knot, so the repaired end hangs slack and shows as a thick place. Careful drawing-in and tensioning during mending prevents it.

Question 50Fabric Construction, Weaves and Fabric Finishes

Which knitting structure is produced on a circular machine with two needle beds and shows the same face on both sides?

  1. Single jersey
  2. Purl
  3. Fleece
  4. Interlock Correct answer.

Explanation

Interlock uses two sets of needles arranged so that alternate loops interlock, giving identical faces on both sides, a thicker fabric and low curl. It is more dimensionally stable than single jersey.
