BTEB Diploma in Textile Engineering Examination study guide
BTEB Diploma in Textile Engineering Examination · Work through your exam, one topic at a time.
The BTEB Diploma in Textile Engineering is a technical vocational credential awarded under Bangladesh's Technical Education Board system, aimed at students and working technicians who want a recognised qualification spanning the whole textile pipeline rather than a single craft. It suits school leavers entering mills for the first time, machine operators and supervisors seeking formal progression, and QA or merchandising staff who need grounding in how fabric is actually made. The BTEB Diploma in Textile Engineering Examination study guide has 11 sections and about 2,658 words.
01Textile Raw Materials and Fibre Science
Begin with the classification tree: natural fibres split into vegetable (cotton, jute, flax), animal (wool, silk) and mineral (asbestos); man-made fibres split into regenerated (viscose, acetate) and synthetic (polyester, nylon, acrylic, polypropylene). Know the polymer repeat units, because questions often ask which linkage defines a fibre - cotton is cellulose with beta-1,4 glucosidic bonds, wool is a protein with peptide bonds and disulphide cross-links, polyester is a condensation polymer of terephthalic acid and ethylene glycol.
279 words, about 1 min02Yarn Manufacturing (Spinning)
For short-staple cotton the sequence is blow room, carding, drawing, combing (for fine yarns), roving and ring spinning. Each stage has a clear purpose: opening and cleaning in blow room, individualisation and sliver formation in carding, drafting and doubling for evenness in drawing, removal of short fibres and neps in combing, attenuation and twist insertion in roving and ring spinning.
268 words, about 1 min03Fabric Manufacturing (Weaving and Knitting)
A woven fabric is formed by interlacing warp and weft. Know the three basic weaves - plain, twill and satin - and their derivatives (rib, basket, herringbone, sateen).
249 words, about 1 min04Wet Processing (Dyeing, Printing and Finishing)
Singeing, desizing, scouring, bleaching and mercerising prepare greige fabric. Each removes a specific impurity: singeing burns protruding fibres, desizing removes size, scouring removes waxes and oils, bleaching removes natural colour, mercerising improves lustre and dye uptake under tension with caustic soda.
234 words, about 1 min05Garment Manufacturing and Apparel Production
Apparel production runs from design and pattern making through grading, marker making, spreading, cutting, sewing, finishing and packing. Understand the difference between block patterns and production patterns, and why grain line and notch placement matter for fit and shade.
233 words, about 1 min06Textile Testing and Quality Control
Testing follows recognised standards and uses representative sampling. Understand the difference between accuracy and precision, and between random and biased sampling.
212 words, about 1 min07Textile Machinery and Maintenance
Know the main components of key machines: card (cylinder, flats, doffer), draw frame (drafting rollers, autoleveller), ring frame (drafting system, spindle, traveller, ring), loom (heddle, reed, shuttle or rapier, sley) and knitting machine (needle, sinker, cam). Understand the function of each part and its adjustment.
183 words, under 1 min08Industrial Management
Planning, organising, directing and controlling are the core functions. Understand types of organisation structure (line, line-and-staff, functional) and the role of the supervisor.
185 words, under 1 min09Costing and Entrepreneurship
Cost comprises direct material, direct labour, direct expenses and overheads. Prime cost = direct material + direct labour + direct expenses.
204 words, about 1 min10Computer Applications and CAD in Textiles
CAD systems support fabric design (weave, dobby, jacquard), garment pattern making, grading and marker making. Understand raster versus vector graphics, colour separation for printing, and repeat setting for textile design.
191 words, under 1 min11Occupational Health, Safety and Environmental Protection
Physical hazards include noise, dust, moving machinery and heat; chemical hazards include dyes, caustic soda and solvents; ergonomic hazards include repetitive strain. Byssinosis from cotton dust is a classic occupational disease.
