Combing is considered as an additional process to improve the quality of yarn in spinning technology. The process is used to produce combed yarn which following carding process. Combing can improve the quality of the raw materials which is operated on the comber.
Objectives of combing process: Combing is used to improve the quality and count of yarn in English counting system. The following are the objectives achieved by combing.
1.To remove short fibers before a pre-selected length.
2.Fiber parallelization is improved by the combing action.
3.Various types of foreign materials and impurities are removed by the combing action.
4.Neps are eliminated by the combing action.
1.Removing short fiber before a pre-selected length.
2.Improving fiber parallelization.
3.Removing various types of foreign materials and impurities.
4.Eliminating neps.
Contribution of combing: Combing improves the properties of yarn. The followings are the contribution of combing.
1.Improving the spinning value (count of yarn).
2.Improving yarn strength.
3.Reducing hairiness of yarn.
4.Speeding up the next process.
5.Reducing imperfection like neps, thick and thin places of the yarn.
6.Achieving better twist.
7.Achieving cleaner yarn.
8.Improving the smoothness of the yarn.
9.Achieving lustrous.
Combed yarn is mainly used as raw materials for knitted fabrics and woven fabrics. The quality of fabrics has close relationship with the properties of yarn. Yarn having high quality can provide efficiency to knitted fabrics or woven fabrics. What is more, yarn should have evenness, should be regular in diameter and CV% should be low and quality ration should be high.
