This dual-layer wrapping method not just boosts the durability and elasticity on the yarn but in addition allows for different twist angles to create several different fabric hand feels.

1. For starters pre-polymer is produced by mixing a macro glycol with a di-isocyanate monomer. They may be mixed inside a reaction vessel and need the right ailments so that they could react to variety a pre-polymer.

The fibers here, may very well be blended with other fibers which include nylon or cotton fiber to make the fabric which is employed for clothes functions. These fabrics can also be dyed so that you can provide a wanted color to them.
