Texturizing is a yarn preparation stage: parallel nylon threads are submitted to a strong twist, they are then fixed by a heat-action and then released to achieve their initial twisting. The end product shows in this way stretch, voluminosity, softness and opaqueness, as well.
Elastomeric Lycra fibre is then covered by nylonThis spiral covering occurs around the Lycra yarn, it can be simple, with only one strand or double, with two strands, one clockwise, the other one counterclockwise
The Lycra fibre percentage contained in pantyhoses can on the average vary from 8 % up to 20 %.
A different method of combination with a yarn being less richt than nylon, i. e. elastomeric fibre, can be obtained by the air-jet technique.
