detailed description

In order to facilitate the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.

As shown in accompanying drawings 1-4, the utility model discloses a kind of polyester warp-knitted elastic fabric, which comprises a fabric body woven with three bars of a single-needle warp knitting machine. The plain cloth section and the mesh section are alternately connected and distributed, and the front bar GB1 and GB2 of the single-needle bed warp knitting machine adopt a yarn-threading structure of polyester filament to form a flat cloth area and a mesh area. The main body and the rear bar GB3 of the single-needle warp knitting machine use elastic fibers to fully penetrate the threading structure to reversely lap the yarn in the plain cloth area and fill in the mesh area to form a base fabric, which is embedded in the main body to form Fabric body with plain and mesh segments. The front bars GB1 and GB2 adopt a warp-forged or warp-bias composite structure when knitting, and the rear bar GB3 adopts a warp-flat structure when knitting.

The yarn threading structure of the front bar GB1 is two threads and two empty spaces, and the lapping number is (45/32/10/23)*3/(45/21)*8//; the yarn threading structure of the front bar GB2 For two empty and double wear, the lapping number is (10/23/45/32)*3/(10/23)/(45/21)*7//; the lapping number of the rear bar is (10/12 )*14//.

The linear density of the polyester filament is between 20-150 denier, and the density of the elastic fiber is between 30-100 denier. The density of the knitting needles of the single-bed warp knitting machine is controlled between 28-40 per inch. The elastic fiber is T400 elastic composite fiber, or yarn similar to T400 elastic composite fiber.

In specific weaving, the following methods are adopted:

1. Yarn warping used in warp knitting:

1) Warping of polyester filament:

Warping machine type: Karl Mayer DS 21/30 NC-2, negative yarn feed.

Warping temperature: 23℃ Warping humidity: 65%

The workshop sets process parameters under the above temperature and humidity conditions.

2) Warping of T400 (or yarn similar to T400):

Warping machine type: Karl Mayer DS 21/30 NC-2, negative yarn feed.

Warping temperature: 23℃ Warping humidity: 65%

The workshop sets process parameters under the above temperature and humidity conditions.

2. Weaving

Weaving machine model: Karl Mayer HKS4-1 EL or other single needle bed warp knitting machine.

Machine number range: E28-E40

The yarn threading methods are two-thread and two-empty, two-empty and two-thread, and full-thread.

The yarn used in this fabric: elastic DTY chemical fiber filament and T400 (or yarn similar to T400).

For example, the schematic structural diagram of the fabric is shown in the accompanying drawings 1 and 2. GB1 and GB2 polyester chemical fiber filaments (DTY) adopt a forged and warp-biased composite structure, and a section of the surface is formed by a pair of yarns passing through each other. Mesh appearance, GB3 special polyester T400 or similar T400 chemical fiber filament (FDY) adopts a warp flat structure in the form of full wear, a section of reverse lap yarn is in the plain cloth area formed by GB1 and GB2, and a section is filled in the small area formed by GB1 and GB2 between the meshes to achieve an invisible mesh effect. The elastic polyester yarn (DTY) used in GB1 and GB2 has certain physical elasticity. GB3 uses a new type of polyester T400 (or yarn similar to T400). T400 polyester (or yarn similar to T400) is subject to certain After temperature treatment, it becomes curved to form a spiral shape and is elastic. Therefore, the two materials are woven together. Although it is all polyester without spandex, the characteristics of the material itself and the structure of the warp-knitted fabric will make the fabric have a certain degree of elasticity in the warp and weft directions. .

3. Dyeing and finishing

(Embryon) overflow dyeing→dehydration→finishing

Note: In the practical technical scheme of this new model, the direct dyeing process of the blank is adopted to ensure better elasticity of the warp and weft directions of the fabric.
