Combed yarns for towels: It is a normal understanding that the towel yarns need to have good absorbency. This is true for towels with honey comb weave or Huck-a-back weaves where there shall be one set of warp yarn and one weft. When we talk of Terry towels, there shall be two warp beams; one for base cloth and the other for piles. Nowadays terry towels are being manufactured on high-speed shuttle-less looms. Therefore, the yarn should be strong enough. 0 TM are used. In case of yarns going for pile, we need higher absorbency and hence low twist is recommended.

Therefore, the mills invest on latest technology. However, in spite of latest, so called “State of the Art technology” we see poor quality of yarn in a number of cases. There are number of factors responsible for the poor quality. They are raw materials, work methods, the condition of the machinery and the management systems adapted. 1 Raw material There is a direct relationship between certain quality characteristics of the fibre and those of the yarn. Seventy to eighty percent of basic yarn quality is decided by the raw material.
