What is the purpose of the combing process?
COMBING PROCESS ( A SPINNING PROCESS): “ The combing is a process which eliminates the short fibres, impurities, naps, immature fibres from the sliver, straightens the fibres and make them parallel along the sliver length”.
Why is combing action necessary in cotton yarn processing?
Combing reduces hairiness of the yarn. It accelerates the next process. Combing reduces imperfection like- neps, thick and thin places of the yarn. Better twist distribution is achieved by the combing action.
How does combing affect yarn strength and evenness?
Ans: Combing improves the yarn strength, evenness and decreases the imperfections due to removal of short fibres and making the fibres more parallel. The percentage improvement in these properties depend upon the amount of noil extracted. The percentage improvement is greater with removal of higher amount of noil.
What is combing in cotton production?
Combing process removes predetermined level of short fibres from the group of cotton fibres. … Since the shorter cotton fibres are generally coarser, removing the shorter fibres leaves behind fibres which are relatively finer. Hence, fabric made from combed cotton fibres has a very soft touch.
What is GREY combing?
Grey combing is done for grey fibre prior to dyeing. Objective of carding machine Individualization of fibre. Removal of trash and dust. Removal of short fibre and nap.
What does comb through mean?
(comb through something) to search carefully among things. Researchers have been combing through data files trying to detect problems. Synonyms and related words. To search for something or someone.
What are the effect of combing on yarn quality?
Combing, therefore, makes possible the spinning of yarns of fine counts with low irregularities and a clear appearance, combing also results in stronger, smoother and more lustrous yarns. In overall spinning process combing operation serves to improve raw material quality by removing noil.
Why combing preparation is required?
Combing the fibres removes the short fibres and arranges the fibre in a flat bundle, with all the fibres going the same direction. This preparation is commonly used to spin a worsted yarn. Woollen yarns cannot be spun from fibre prepared with combs, instead, the fibre must be carded.
What does the word combing mean?

What is the difference between combed cotton and Egyptian cotton?
Egyptian cotton is extraordinary – producing extra-long fibres that are smaller in diameter than regular cotton. These longer, finer fibres create super smooth yarns when combed and spun, and therefore super smooth, soft cloth when woven.
