Improvement in Jute Yarn Quality Ratio by Incorporation of Draw Head System at Carding Stage

Abstract

Soumita Chowdhury, Pandit Sandip

Jute as very unique natural bast and its industrial manufacturing started in India from around 1855. Till then jute processing machinery and the processing system progressed very slowly. Presently jute fibre/yarn used in several diversified products other than food grain packaging bag. To improve the quality of jute yarn a study has been carried out in a jute mill where the quality of jute yarn produced by usual finisher card (fitted with roll former) is compared with quality of yarn produced by the draw head fitted finisher card system. As two types of draw head systems are available presently, total three process are compared based on yarn quality produced by them.

It is found that draw head plays an important role on jute yarn quality in comparison to simple finisher card with roll former system. Specially the yarn produced by L make draw head system shows uniform controlled average sliver weight, lower sliver and yarn CV% better evenness and higher minimum yarn strength in yarn.

Traditional drawing frames are used for regular jute yarn, now-a-days by using draw heads in jute mills will improve the quality of the output sliver. This sliver is producing regular and fine jute yarn with higher tensile strength, work of rupture, breaking elongation and quality ratio and count variation percentage. The produced modified yarn was also more regular and uniform comparing to the traditional drawing frame.
