Knitwear and Circular Knit Products

Why knitted garments behave differently — and how to specify, sew and control them so the fit stays put.

A free, self-paced specialist course on knitwear: knit structures and how they stretch, yarn and fibre choices, engineering t-shirts, polos, sweaters and seamless products, and controlling shade, shrinkage and measurements in a fabric that moves. Three modules, each ending with a five-question quiz.

  • 3 modules · 12 subjects
  • About 8–10 hours of reading and quizzes at your own pace
  • 3 quizzes to check your understanding

  • Merchandisers and technicians working on knit programmes
  • Quality staff who measure and inspect knitted garments

  • Students specialising in knitted apparel

What you will be able to do

  • Explain how a knit structure decides stretch, recovery, curling and spirality
  • Choose yarn and fabric for a knit end use instead of copying a previous order
  • Engineer the common knit products — tee, polo, sweater, seamless — to their own construction rules
  • Control shrinkage, shade and measurement variation across a knit bulk
  • Judge which knit faults are fabric faults and which are sewing faults

Preview module

Module 1 — Knit fabric foundations

Read a knit fabric specification and predict how the garment will stretch, recover, shrink and curl before a sample is made.

Sample quiz question from this module

Why does a single jersey edge curl while an interlock edge lies flat?

  1. A. Single jersey is heavier
  2. B. Single jersey has different loop structures on face and back, so the fabric relieves its stress by curling; interlock is balanced
  3. C. Interlock is always finished with resin
  4. D. Curling depends only on the cutting table
Show the answer

B. Single jersey has different loop structures on face and back, so the fabric relieves its stress by curling; interlock is balanced Curling comes from an unbalanced structure, not from weight. Balanced double-knit structures such as interlock and rib have no reason to roll.
