Quality Control:

Proper quality of products can be maintained by checking the material at the different stages a take proper action or decision. For yarn manufacturing process, yarn quality control and testing can be classified in to three ways. They are as follows-

  1. Fiber Testing Equipment
  2. Lap, Sliver and Roving Testing Equipment
  3. Yarn Testing Equipment

Quality Control Equipment for Yarn Manufacturing :

To check the material quality, the following equipment are required in Quality Control department of a modern yarn manufacturing mill or spinning mill-

Different Types of Quality Control Equipment

1. Fiber Testing Equipment:

  • HVE-for fineness, color, trash, strength and length measurement.
  • AFIS-for neps, seed coat neps, size of neps, fiber length, short fiber content, dia/fineness, immature fiber content, no. and size of trash, no. and size of dust.
  • Shirley analyzer-for trash content measurement.
  • Nep counter-for fiber length, neps, sort fbre% measurement.
  • Fiber bundle strength tester(Pressley/Stelometer)-for strength testing.
  • Moisture regain tester-for M.R.% testing.
  • Rapid conditioning unit.
  • Sugar of strictness tester-for testing honey dew.

2. Lap, Sliver and Roving Testing Equipment:

  • Lap length counter.
  • Balance ,scale, warp block- for testing sliver and roving hank.
  • Nep counting board.
  • Auto sorter-for sliver count testing.
  • Evenness tester-for testing lap and sliver irregularity.

3. Yarn Testing Equipment:

Yarn Package

  • Warp reel and balance-yarn count testing
  • Auto sorter-for count and C.V.% analyzer
  • Evenness tester (USTER3)-yarn imperfection, U.I%, spectrometer, hairiness.
  • USTER classimat-yarn fault classify.
  • Yarn tension meter
  • Twist tester
  • Single yarn and lea yarn strength tester.
