Benefits of technology

The present invention is about providing an elastic warp knitted fabric that has a peach-skin-like feel, resists snagging, and has a wide range of density options and applications in the garment industry. This is achieved by using a double-needle overlap structure of combined chemical filament yarns and spandex yarns that can be guided by a single or separate guide bar. The two types of 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.

Embodiment Construction

Warping of the Yarns

(1) Warping of Chemical Filament Yarns;

[0011]Warping machine: Karl Mayer DS 21 / 30 NC-2, passive feeding mode.

[0012]Warping temperature: 23° C.; Warping humidity: 65%.

[0013]The process parameters should be set according to the above temperature and humidity conditions.

(2) Warping of Spandex Yarns:

[0014]Warping machine: Karl Mayer DSE-H21 / 30 NC-2, with positive feeding mode.

[0015]Warping temperature: 24° C.; Warping humidity: 78%.

[0016]The process parameters should be set according to the above temperature and humidity conditions.

The Knitting Process

[0017]Knitting machine: KarlMayer HKS2-3, HKS2-3E, HKS3-1, HKS4-1, RSE4-1 or any other single needle bar warp knitting machine.

[0018]Machine type region: E28-E50

[0019]Threading mode: full-threading.

[0020]Two types of yarns are used in this fabric: chemical filament and polyurethane fiber.

[0021]The warp knitting process as well as the characterizes of the fabric produced is mainly defined by the lapping moments of the gu...

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...
