ABSTRACT
In Chapter 3, it was explained that one of the main functions of a card is to disentangle tufts of fibers into a web of individual fibers. In this respect, important considerations are the process of fiber individualization, the formation of the doffer web, the fiber extent and configuration, and the degree of fiber damage during carding. This is because, in processes subsequent to carding, fiber breakage and poor fiber configuration may lead to unacceptable yarn irregularity and imperfections. As described in Chapter 5, fiber individualization and fiber hooks have a major influence in combing and drafting processes and therefore, ultimately, on the yarn quality and spinning performance.
