Drafting of jute: Part II-Towards making regular yarns

It has been observed that the contribution of drawing machine to the irregularity of finisher drawing sliver and yarn is maximum. The effect of carding machines on irregularity may be reduced to minimum by repeating at least one drawing operation as a leveller at a suitable stage. The use of leveller reduces the long-term variation of yarn significantly; a minimum value of 3% could be achieved for a yarn of 278 tex. However, the use of leveller has limited effect on short-term variation, which is expected to be reduced around 13% through modification of finisher drawing machine or incorporation of other drafting system at this stage.</span>
