Embodiment Construction

[0030] Referring to the figures listed above, the fabric according to the invention is designated 1 as a whole.

[0031] It is produced by a warp knitting machine with at least two rows of weft carriers.

[0032] Said machine is of a known type, for example a warp knitting machine commercially available under the trade name Copcentra from the German company LIBA Maschinenfabrik GmbH.

[0033] As already mentioned, said machine comprises a system for conveying and moving the yarn, suitably arranged on the weaving beam, which is inserted into the two bars of the perforated weft carriers and conveyed to the needle bed.

[0034] In particular, two yarn guide rods are arranged one at the front and the other at the rear, and can move in a linear reciprocating motion in the longitudinal and transverse directions.

[0035] Furthermore, the same type of yarn is fed to each yarn guide rod, while two different types of yarn can be selectively fed to two different rods.

Abstract

The invention describes a method for manufacturing non-run elastic fabrics on a warp knitting / weft knitting loom with two weft yarn carrying bars and a needle bed, wherein, one of the two weft yarn carrying bars is prearranged with rigid yarn (2) and the other is prearranged with elastic yarn (3), additionally, rigid yarn (2) and the elastic yarn (3) are arranged in phase according to four-loop cycle, wherein three continuous loops are obtained on three different continuous knitting needles.

Description

technical field [0001] The object of the present invention is a method for producing non-spun elastic fabrics on a warp knitting machine with two guide bars and a needle bed, which method consists in presetting rigid yarns on one guide bar and on the other Elastic yarn is preset on the yarn guide rod. Background technique [0002] As is well known, fabrics are formed from a plurality of yarns arranged according to a specific periodic geometry so as to interconnect them and form loops. [0003] The characteristics of the fabric are thus determined by the geometry of the weave, the type of yarn and ultimately by the individual loop dimensions. [0004] In particular, so-called non-spun elastic fabrics are formed from a plurality of weaving yarns, called warp yarns, extending in a single direction. [0005] The fabric is constructed from a number of different types of yarns, in particular substantially rigid yarns and substantially elastic yarns. [0006] Non-snagging elasti...
