INTRODUCTION Raschel machines for producing stretch and non-stretch

sportswear, lingerie and tulle, as well as fine and coarse nets.

Raschel knits do not stretch significantly and are often bulky; consequently, they are often used as an unlined material for coats, jackets, straight skirts and dresses. These fabrics can be made out of conventional or novelty yarns which allows for interesting textures and designs to be created.
