ABSTRACT
The laid-in fabrics are built of at least one ground bar with usually full threading and at least one laid-in guide bar, that does build loops, but only places underlaps. These are very common for crochet-knitting machines for production of elastic and stable meshes, medical and fashion tapes, decoration textiles and as well for the Raschel machines for decorative home textiles. The laid-in yarns limit the elongation of the fabrics in horizontal direction similar to the weft yarn in woven fabrics. The less elastic laid-in yarns reduce the elongation of the structures and can make them stable in both wales and course direction, so that they have the same stability as woven structures. The creative use of laid-in yarns allows not only filling areas and side movement of the chains, it allows production of larger figures as well based on thinner and thicker lines.
