In spinning process; winding are the last steps. After winding yarn packages are used for making woven or knitted fabrics. Winding process can be defined as the transfer of spinning yarn from one package to another large package (cone, spool, pirn etc). On the other hand it can be defined as the transfer of yarn from ring bobbin, hanks etc into a convenient form of package containing considerable long length of yarn. A process of accumulating yarn on a package to facilitate the next process is called as winding.
Objectives of winding: Winding process has some objectives which are given as below:
- To transfer yarn from spinning bobbin package to a convenient yarn package.
- To improve the quality of yarn.
- To get suitable yarn package.
- To get a quality fabric.
- To get good warp yarn.
- To empty the spinner’s bobbin so that it can be used again.
- To remove dust and clean the yarn.
- To reduce labor cost.
- To store the yarn.
- To improve the efficiency of yarn for next process.
Requirements of winding: Winding process should be accurate for accelarate the next fabric manufacturing process. Winding process should fulfill the following requirements.
- Winding process should be easy.
- Characteristics of the yarn should not be changed.
- Winding faults should be minimize.
- Yarn package size and shape should be suitable.
- Winding process should be economical.
- Yarn package should be cheap in cost.
- Avoid excess looseness or tightness.
- Exact package hardness.
- In winding, yarn knots should be small in size and amount of knots should be minimum.
So, that’s all about winding process and objectives and requirements of winding.
