Objectives And Requirements of Soft Winding Section | Yarn Dyeing Process

Soft Winding

Yarn dyeing is a special type of dyeing. Package yarn dyeing is done in package form. For this reason, it needs to transfer the yarn from the paper cone to the spring tube or plastic tube. This function is done in a soft winding section where rewinding is done. Different modern winding machine is used for winding function. Here different parameter is maintained which effect the dyeing process directly.

The soft winding section is an important part of the yarn dyeing industry. It is the first step in preparing yarn for dyeing. If the winding process is not accurate then it affects the dyeing process.

Objectives of Soft Winding:

A different function is done in the soft winding section. The Following objects are required to gain in the soft winding section. They are-

  1. Firstly, to make soft package (Density should lies between 0.300-0.350gm/cc).
  2. Secondly, to transfer yarn from cone to spring tube or plastic tube.
  3. Thirdly, soft winding is essential to make free the cone from yarn to facilities next process.
  4. After that, to reduce the density of package.
  5. Therwefore, it use to remove unwanted materials from the package.
  6. Lastly, to facilities batching operation.

Requirements of Soft Winding Section:

In the winding section, various parameters are set to produce the required package which is best for yarn dyeing. The following are the requirements for the soft winding section. They are-

  • The density of the package should be uniform, because it allows better penetration of dye liquor to the yarn.
  • The density value should be lies between 0.30 – 0.35 gm/cc or 300 – 350 Kg/M3
  • Winding should be performed according to the yarn count.
  • Tension of yarn during winding process should be maintained strictly because more tension makes the package hard and less tension makes the package softer. But softness of package should be at an acceptable level for better dyeing of yarn.
  • Winding section floor should keep neat and clean.
  • Winding parameter for different yarn count should set wisely.
  • More tension can occur more breakage of yarn, low tension makes softer package. So, tension should be accurate.

 So, we have to be sincere in the soft winding section for getting the correct density yarn package which gives better dyeing proficiency.

  1. If I have automatic cone to cone Murata machines with automatic splicer.
    I am a dyehouse that is dyeing cotton for third party.
    My count varies from Ne 20/1 to Ne 120/2.
    How many spindles for each operator .
