Warp knitting elastic fabric and method of fabricating therefore

Abstract

Warp knitting fabric having a double needle overlap structure forming two loops on two adjacent needles in the same course, and loops being formed from double yarns one of which is a chemical filament yarn and the other yarn is a spandex yarn, and both of the yarns being knitted with the same lapping movement.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims benefit from Provisional Application No. 61 / 930,959, filed Jan. 14, 2014, the content of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention relates to a knitted fabric, particularly to a warp knitted fabric with a double needle overlap structure and combinational yarns.BACKGROUND OF THE INVENTION[0003]Warp knitted fabrics have been widely used in women's underwear and close-fitting undergarment for maintaining a desirable body part profile. Presently, fabrics for such purposes are mostly warp knitted elastic fabrics with a locknit stitch structure (typically shown in FIG. 1), where the warp pile (velvet) is formed from chemical filament yarns from the front guide bar and half tricot base stitches are formed from spandex yarns from the back guide bar. The textile made this way has reasonably good elasticity and comfortable hand feel, and that is why it has dominated the elasti...

AI Technical Summary

Benefits of technology

[0004]Accordingly, one object of the present invention is to provide an elastic warp knitted fabric which has a sufficient elasticity, special hand feel mimicking the peach skin, good resistance to snagging, wide range of density possible between 100 and 350 grams per square meter and wide range of suitable applications in the garment industry. This object is achieved by a warp knitted fabric with a double-needle overlap structure (or double loop stitch) of combined chemical filament yarns and spandex yarns, which may both be guided by a single guide bar or may be guided separately by two guide bars. In other words, the two types yarns have exactly the same lopping moment.

Problems solved by technology

Nonetheless, there are drawbacks in the textile with such stitch structure: the elasticity is not sufficiently great as desired, Although, the elasticity may be improved by using thicker polyurethane (i.e., spandex) yarns, thicker spandex yarns bring other problems such as curliness, exposure of the spandex yarn to the surface, poor color fastness, poor elastic recovery rate, and appearance of wrinkles after repeated stretches.
