| Abstract: | Detailed analysis of card web/sliver and other post-card products has been done for obtaining improved understanding about the changes in the characteristics of card web/sliver with carding quality and the impact of carding quality on the properties of yarn spun on different spinning systems. The analysis has shown that although the routine tests of carding quality such as trash in sliver, neps in card web, cylinder load, etc. assist in grading carding quality, other card web characteristics such as evenness in card web weight per unit area, short term variation in sliver thickness, fibre parallelization, fibre to fibre separation are also important parameters of card web contributing to carding quality. Although bad carding gives better parallelization, the rate of improvement in parallelization in the subsequent processes is better with good carding, probably due to better fibre separation. Fibre separation seems to influence carding quality more than fibre parallelization. The size of trash particles does not change much with carding condition. Open end spinning has been found to be more sensitive to carding condition both for performance and yam quality than ring spinning. These findings suggest that by carding material under adverse conditions many carding quality characteristics other than the routine ones get changed and the influence on spinning performance and yarn quality depends on the spinning system used. |
