What is modified stretched yarn?
Modified stretch yarns: They are produced by the presence of second heating zone during false twist or edge crimping process. They have moderate stretch (100-150%) with high bulk. Bulk yarns: They are produced by fear crimping, stuffer box, air jet and knit-de-knit processes. They have no stretch and high bulk.
Which type of yarn is often used to increase elasticity?
The two fibers most widely used in making stretch yarns are nylon and polyester. Yarns with similar or greater elastic stretch can also be produced using an elastomeric thread as the core and wrapping it with a nonstretch textile fiber bundle, filament or staple (Fig. 1.7).
