ABSTRACT

In this chapter, some of the normally observed defects in false-twist texturising are discussed. The defects normally found in a texturised yarn can be grouped as follows: (a) Yarn defects due to process variation (b) Yarn defects due to setting variations (c) Yarn damages (d) Winding defects due to process variations (e) Winding defects due to setting (f) Defects due to damaged parts in machine (g) Defects due to machine setting (h) Defects due to human work practices The following are the grouping done while observing the actual defects in a texturised yarn and process.
