Flow Chart of Spinning Finishing Section

  By

In spinning mill, after making yarn the others process is called finishing. Yarn faults remove; color mix check, right shape of yarn package and many others work done by this section. That’s why it is very important section.

Flow Chart of Spinning Finishing Section

Flow of spinning finishing section is started with Spinning=>Yarn in cop package=>Winding=>Yarn in cone package=>checking under ultraviolet light=>Conditioning (Heat seat) =>Weight determination=>Packing and finally=>Delivery to buyer

Types of winding

According to winding way:

There are basically two types of winding. They are

  1. Precision winding
  2. Non precision winding

Precision Winding

The winding process in which yarn is laid close together in a parallel or near parallel manner is called precision winding. Maximum amount of yarn storing is possible by this system.

Non precision Winding

The winding process by which yarn is laid in helix angled way so that the layers cross one another and give stability to the package is called non precision winding. These types of winding package are more stable than precision winding package.

According to package winding can be classified as:

  • Pirn winding
  • Pool winding
  • Cop winding
  • Cone winding
  • Cheese winding
  • Flanged winding

Objectives of winding

  1. To transfer yarn from one package to another package.
  2. To remove faults like hairiness, neps, slubs, foreign matters.
  3. Improve the quality of yarn.
  4. Reduce the end breakage.
  5. Improve productivity.
  6. To store the yarn in suitable package.
  7. To get required package of yarn.

Requirements of winding

  • Minimum fault
  • No damage of yarn
  • Easy unwinding
  • Suitable size and shape
  • Correct tension
  • Cheap cost of package

Faults during winding:

  • Breakage of yarn during winding
  • Variation of twist
  • Improper shaped winding
  • Dirty packages
  • Hairiness package
  • Poor unwinding
  • Softer or harder winding package in great rate etc.
