Özet

The effects of various twisting nozzle constructions on the structures of lyocell, cotton and polyester/cotton two-fold yams produced with PLYfiL 1000 system have been studied. It is observed that the yams basically consist of wrapped and unwrapped lengths, and can be classified into 4 categories on the basis of their structure. The effect of proportion and length of each class on tenacity and extension of both untwisted and twisted yams has also been studied. The construction of the twisting nozzle affects the physical properties of the yams produced and the yarn structure that has tight and regular wraps around the core fibres influences the tenacity of the yams positively.
