Wefts belong to the knitted fabric group of products and are characterized by multiple loops of yarns, called stitches. They are produced through stitch formation of one or more thread systems. Depending on the bond or material, this process can create inelastic, mono-elastic or bi-elastic textiles.
These materials are used in combination with very elastic outer fabrics. Using very fine threads, very light textiles can be produced.
These materials can made either elastic or stable. With particularly high elasticity in the weft direction, bi-elastic textiles are being ever more widely used. They adapt perfectly to the outer fabric material and increase the wearing comfort of the garment.
To achieve increased stability in the length or machine direction, a stitched fringe is worked in the nonwoven base material . Depending on the used threads and finishing process, textiles with elasticity in warp direction can also be produced.
