Compact Spinning Effect on Cotton Yarn Quality: Interactions with Fiber Characteristics

The impact of card cylinder speed, card production rate and draw frame doubling on cotton yarn quality parameters was investigated by using the Box-Behnken experimental design. It was found that yarn tenacity, elongation and hairiness increase by increasing the number of draw frame doubling up to a certain level and then decrease by further increase in doubling. Yarn unevenness increased by increasing card production rate and total yarn imperfections increased by decreasing card cylinder speed and increasing card production rate.

Yarn Production

The textile and garment industry fulfils a pivotal role in the Indian economy. It is a major foreign exchange earner and, after agriculture, it is the largest employer with a total workforce of 35 mn. In 2005 textiles and garments accounted for about 14% of industrial production and 16% of export earnings. In cotton yarn production India has made a mark in the world textile scenario. It is the largest exporter of the cotton yarns in the world. Besides yarn exports, Indiaâ€™s growing garment industry is working as a driving force to improve the yarn quality and to increase the production of cotton yarn. This has resulted in an overall improvement in the quality of all textile products including yarn and fabric. The WTO era has seen remarkable improvement in export of textiles. To help the mills in bench marking, SITRA has conducted a survey on the cotton yarn quality for fine and superfine yarns, in which 58 mills from all over India have taken part.

Fluent 6.3

The flow field in condensing zone of compact spinning with inspiratory groove was developed with Fluent 6.3 and the distribution of velocity was analyzed too. Also the effect of negative pressure on the yarn quality was analyzed and the experiment was done to prove the effect of negative pressure on the yarn qualities. The results show that the fiber can not be compacted well when negative pressure is too small, but it will add the energy consumption, attach the fibers firmly to the bottom of the compact groove by the effect of flow field and reduce the fiber migration, cause the fibers to be absorbed from the holes or the holes to be plugged when the negative pressure is too big. Therefore, in order to ensure the fibers being compacted well and reduce the energy consumption, the selection of negative pressure in compact spinning with inspiratory groove should be less than -3000pa.

Accuracy Of Prediction

Earlier work at ATIRA has shown that there exists a quantitative relationship between warp-breakage rate and grey cotton yarn quality. This work attempts to restructure the earlier formula in such a way that it can be used to predict individually the relative contributions of three factors: the general inadequacy of yarn to withstand the load, stretch, and abrasion imposed on it during weaving; the obstruction or tensile/abrasive failure of thick places; and the failure or obstruction of knots and other miscellaneous faults. The formula has also been extended to blend yarns, and the accuracy of prediction is quite high.
