Embodiment 1

[0019] Three-dimensional structured warp-knitted fabric.

[0020] The fabric is woven by a single-needle bed warp knitting machine with a needle selection device to form a common fabric base 1, and a plurality of three-dimensional protrusions 2 are formed by weaving in its thickness direction. The cross-sectional area of ​​the three-dimensional protrusions 2 is based on the The number of knitting needles is adjusted, and its height is adjusted according to the number of courses involved in knitting.

[0021] refer to Figure 1~4 , the three-dimensional protrusions 2 are locally distributed on the surface of the fabric.

[0022] refer to Figure 3-4 , a plurality of three-dimensional protrusions 2 are mutually independent in terms of cross-sectional area and height during weaving.

Embodiment 2

[0024] A weaving method for warp knitted fabrics with a three-dimensional structure.

[0025] This method is used for weaving the warp knitted fabric with three-dimensional structure in Example 1.

[0026] Wherein, the ordinary fabric base 1 is woven by a single-needle bed warp knitting machine with a needle selection device. When knitting the three-dimensional protrusions 2, some knitting needles knit in some courses to form more loops than other unknitted knitting needles. Course, after the machine is off, the excess coil courses form protrusions on the surface of the fabric due to the tension of the rest of the coil yarns, forming a three-dimensional structure.

[0027] The cross-sectional area of ​​the three-dimensional protrusion 2 is adjusted according to the number of knitting needles involved in weaving, and its height is adjusted according to the number of courses involved in weaving.

Abstract

The invention discloses a warp-knitted fabric of a three-dimensional spatial structure and a knitting method of the warp-knitted fabric. When the spatial structure is knitted, part of knitting needlesconduct knitting on some transverse rows to form coil rows more than non-knitted coil rows on other knitting needles, after the operation is completed on a warp-knitting machine, excessive coils formprotrusions on the surface of the fabric due to the fact that other coil yarns are in a tensioning state, and the spatial structure is formed. According to the warp-knitted fabric of the three-dimensional spatial structure and the knitting method of the warp-knitted fabric, knitting can be conducted on the warp-knitting machine with a single needle bed, the knitting technology is simple and easyin operation, the pattern changes are rich and diversified, and the product application field is wide.

Description

technical field [0001] The invention relates to the field of warp-knitted fabrics, in particular to warp-knitted fabrics with a three-dimensional structure and a knitting method thereof. Background technique [0002] Warp knitted fabrics are mainly knitted fabrics formed by synchronously forming loops by feeding one or several groups of yarns arranged in parallel into all the working needles of the warp knitting machine at the same time. Usually warp knitting machines can weave two-dimensional fabrics, but special weaving processes can also weave three-dimensional fabrics. Three-dimensional fabrics can be divided into three-dimensional forming fabrics and three-dimensional spacer fabrics. The most common warp-knitted three-dimensional fabric is the cylindrical warp-knitted fabric, such as artificial blood vessels, women's pantyhose, etc. The three-dimensional spacer fabric is composed of independently woven upper and lower surface layers and a middle connecting layer, such...
