BI-STRETCH DENIM MANUFACTURING

I have received a query from one of my blog readers who wants to know more about bi-stretch denim manufacturing. I feel there are some specific issues that need to be delt with while dealing with bi-stretch fabric at the manufacturing stage:

1. How to control yarns at the ball warping, rope dyeing and the rebeaming stage.
2. Changes in looms to be done to handle stretch warp and stretch weft. It includes issues such as width control and others.
3. Sanforisation and skew control at the finishing stage.

If someone can contribute to this blog regarding these questions, she/he is most welcome.
