UPMSP Weaving Technology study plan

UPMSP Weaving Technology · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Loom Mechanisms and Motions & Textile Fibres and Yarn Fundamentals

  • Sketch and label the five primary loom motions (shedding, picking, beating-up, let-off, take-up) and state the function and timing of each in the loom cycle

  • Define the secondary and stop motions and explain which fabric/ yarn faults each one is designed to prevent

  • Classify natural, regenerated and synthetic fibres by origin and property, and match each to typical weaving behaviour (drape, crimp, elongation)

  • Explain yarn numbering systems (Ne, Nm, Tex, denier) and convert at least ten values between systems by hand

  • Describe how twist level and direction affect yarn strength, hairiness and abrasion resistance in the warp and weft

Your checkpoint

A hand-drawn loom motion diagram with all eight motions labelled plus a one-page yarn-count conversion table showing 10 worked conversions

Week 2

Loom Mechanisms and Motions & Fabric Structure and Weave Design

  • Trace the shedding cycle for tappet, dobby and jacquard shedding and identify which fabric complexity each suits

  • Compare early and late shedding and explain the effect of shed geometry on warp strain and pick spacing

  • Draw the pegging/chain plan for a given weave repeat and read an existing chain plan back into a weave

  • Analyse picking systems (overpick, underpick, projectile, rapier) by the force path and the timing constraints they impose

  • Explain how sley eccentricity and beat-up timing influence pick density and fabric cover

Your checkpoint

A worked loom timing chart (crank angle from 0 to 360 degrees) marking shed opening, pick, beat-up and shed crossing for one chosen weave

Week 3

Fabric Structure and Weave Design

  • Construct the weave, draft and peg plan for plain, twill (2/1, 2/2, 3/1), satin and sateen weaves from first principles

  • Derive the repeat size, warp/weft float lengths and interlacing factor for each family and predict fabric handle from them

  • Design a colour-and-weave effect and a simple stripe/check using a given weave base

  • Calculate ends per inch, picks per inch and weave density from a fabric sample description and check whether the design is weaveable on a given loom

  • Explain how weave structure affects crimp, cover factor and tear strength

Your checkpoint

A design portfolio of five weaves, each with weave diagram, draft, peg plan, float analysis and a two-sentence handle prediction

Week 4

Warp Preparation and Sizing & Loom Mechanisms and Motions

  • Sequence the warp preparation route from winding through warping, sizing and drawing-in, stating the quality check at each stage

  • Compare direct and sectional warping and justify a choice for a given order size and colour pattern

  • Explain sizing recipe components (size agent, lubricant, binder, preservative) and their separate functions

  • Calculate size add-on percentage, size pick-up and moisture regain targets from given figures

  • Relate warp breakage rate to sizing quality and identify the loom settings that compensate for poor sizing

Your checkpoint

A one-page warp preparation flow chart with the acceptance criterion and the common fault at each of the six stages

Week 5

Weaving Operations and Production Control & Textile Calculations and Costing

  • Calculate loom efficiency, picks per hour, production in metres per shift and machine utilisation from raw shift data

  • Compute the number of looms per weaver and per shift from allocation and workload data

  • Convert fabric weight per square metre into GSM-related costing inputs and calculate yarn consumption per metre of fabric

  • Build a simple cost sheet covering yarn, sizing, power, labour, depreciation and overheads, and derive cost per metre

  • Diagnose a production shortfall by separating losses into warp stops, weft stops, maintenance and organisational causes

Your checkpoint

A spreadsheet-style calculation sheet solving five set problems on efficiency, production and cost per metre with all steps shown

Week 6

Fabric Defects, Quality Assurance and Inspection & Weaving Operations and Production Control

  • Catalogue warp-way and weft-way defects with their root cause, the responsible machine part and the corrective action

  • Explain the 4-point and 10-point grading systems and grade a described fabric roll

  • Describe the inspection sequence on a fabric inspection machine and the significance of a cuttable-width check

  • Set up a stop-rate monitoring routine and interpret a rising end-breakage trend

  • Distinguish a machine fault from a material fault when the same defect repeats across several looms

Your checkpoint

A defect diagnosis table of at least 15 defects with cause, machine part and remedy, plus a graded sample roll calculation

Week 7

Maintenance, Safety and Workshop Practice & Modern Weaving Technology and Automation

  • List the scheduled maintenance tasks for tappet loom, dobby and rapier loom at daily, weekly and monthly intervals

  • Describe safe isolation and lock-off procedure before clearing a warp or weft jam, and the PPE required on the weaving floor

  • Explain the working principle of modern looms: air-jet and water-jet weft insertion, electronic let-off and take-up, and automatic pick finding

  • Compare modern automation features (electronic dobby, quick style change, online monitoring) by their effect on efficiency and downtime

  • Identify the workshop hand tools and gauges used for loom setting and state what each one measures

Your checkpoint

A two-part sheet: a maintenance calendar for one loom type and a 10-item safety checklist for a jam-clearing procedure

Week 8

Textile Fibres and Yarn Fundamentals & Fabric Structure and Weave Design & Loom Mechanisms and Motions & Warp Preparation and Sizing & Weaving Operations and Production Control & Fabric Defects, Quality Assurance and Inspection & Textile Calculations and Costing & Maintenance, Safety and Workshop Practice & Modern Weaving Technology and Automation

  • Re-solve one representative calculation from each of the nine domains under timed conditions

  • Redo every previously missed question and record the corrected reasoning in one line each

  • Recite the weave, motion, sizing and defect definitions from memory without notes

  • Sit two full-length mock papers and review both before the next session
