Procedure for manufacturing ladderproof fabrics

Abstract

A procedure for manufacturing ladderproof fabrics on a warp knitting machine (1) comprising stitch-forming members (4) and at least one guide bar (2), with a plurality of guides (2a) for guiding a plurality of yarns (10) towards the stitch-forming members (4), wherein each of the guides (2a) belonging to at least one of the guide bars (2) guides a plurality of yarns (10).

Description

FIELD OF THE INVENTION[0001]The present invention relates to a procedure for manufacturing ladderproof fabrics on a wrap knitting machine, comprising stitch-forming members and at least one guide bar, with a plurality of guides, comprising at least one eyelet, for guiding a plurality of yarns in the direction of said stitch-forming members, and a fabric obtained by means of said procedure.DESCRIPTION OF THE PRIOR ART[0002]It is common knowledge that fabrics are made of a plurality of yarns placed in particular recurrent arrangements that enable said yarns to be linked together to form stitches.[0003]The characteristics of fabrics are thus determined by the arrangement of the yarns in the pattern, the type of yarn used and, finally, the dimensions of the single stitches.[0004]In particular, the so-called ladderproof elastic fabrics are made using a basic pattern comprising a plurality of yarns running in the same direction, called the warp, with a combination of substantially inelast...

AI Technical Summary

Benefits of technology

[0019]Within the context of said technical aim, a major object of the invention is to realise a procedure for manufacturing ladderproof fabrics, and particularly suitable for making fabrics comprising a basic pattern with yarns arranged parallel to one another, that have an improved appearance and surface feel.

[0021]The technical aim and objects specified above are achieved by a ladderproof elastic fabric realized on a wrap knitting machine comprising stitch-forming members and at least one guide bar, with a plurality of guides, comprising at least one eyelet, for guiding a plurality of yarns in the direction of said stitch-forming members by means of procedure in that each of said guides belonging to at least one of said guide bars guides a plurality of yarns by means of said eyelet. The said fabrics have considerably improved characteristics in terms of appearance and feel.

Problems solved by technology

Being difficult to dye and unattractive, the elastic yarns in such fabrics are hidden by the inelastic yarns.

It has been demonstrated, however, that the elastic yarns sometimes do not remain aligned behind the inelastic yarns and they emerge on the surface, with a negative fallout on the appearance and feel of the fabric.

It is also worth noting that yarns with a very fine titre cause a reduction in the productivity of knitting machines and a consequent increase in the cost of manufacturing the related fabrics.
