Description

Warp-knitted spacer fabric with honeycomb structure

Technical Field

The utility model relates to a surface fabric development technical field, in particular to warp knitting spacer fabric with honeycomb structure.

Background

The warp knitted fabric is a knitted fabric formed by simultaneously knitting one or more groups of warp yarns into loops and mutually interlooping the warp yarns on a warp knitting machine. In such a knitted fabric, each yarn of a set of warp yarns forms only one or two stitches in one course and then forms a stitch again in the next course. The stitches formed from one yarn are arranged along the warp direction of the knitted fabric.

A warp knitted fabric formed of a group of yarns is called a single-bar warp knitted fabric, and each stitch is formed substantially by one yarn. The double-bar warp-knitted fabric is formed by weaving a front bar and a rear bar. For example, the front comb is laid with warp pile weave and the back comb is laid with warp flat weave, and this double-comb warp-knitted weave is called warp flat pile weave. Each loop of the double-comb warp-knitted fabric is basically knitted by two yarns, and the loop is stable in structure and flat in surface. Multi-bar warp knitting fabrics are typically woven from two bars to provide the desired properties to the fabric, with the remaining bars being threaded with warp yarns to provide a pattern on the fabric. Warp-knitted fabrics are of two types, single-sided and double-sided. Single-sided warp knitted fabrics are knitted in a single-bed warp knitting machine, one side of the fabric consisting of stitches and the other side being provided with stretch threads of stitches. Double-sided warp knitted fabrics are woven in a double needle bar warp knitting machine, the fabric being composed of stitches on both sides, and the spreading threads of the stitches being among the stitches on both sides. Warp knitted fabrics are of a wide variety, can be used as underwear, outerwear, curtain, lace and the like, and are also widely applied in the fields of industry, agriculture, medical treatment, health care and the like.

A spacer fabric is a fabric with two or more layers formed by several groups of yarns, wherein one group of yarns is required to play a connecting role. The spacer fabric is composed of a multi-layer structure, and the stable and attractive appearance can be formed only by considering the matching of the structures of the layers during weaving.

The utility model provides a warp knitting spacer fabric with honeycomb structure.

Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

In a specific embodiment, as shown in fig. 1 and 2, a warp-knitted spacer fabric having a honeycomb structure includes an upper surface layer a, a lower surface layer B and an intermediate layer C, the upper surface layer a and the lower surface layer B are plain weave, and the cross-section of the fabric is a honeycomb structure.

The fabric is made of polyester yarns.

The specification of the polyester yarn is any one specification of 50D-300D.

The surface density of the fabric is 200 threads/5 cm at the warp density and 160 threads/5 cm at the transverse density.

The embodiment combines with special design, and the surface of the warp-knitted spacer fabric is plain weave, so that the warp-knitted spacer fabric has good structural stability and high mechanical property. The warp-knitted spacer fabric is composed of three layers: an upper surface layer A, a lower surface layer B and an intermediate layer C for connecting. The honeycomb-shaped structure of the warp-knitted spacer fabric is now a cross section of the fabric, obtained by controlling the connection sequence of the intermediate layer C. The pore size of the honeycomb mesh is obtained by the number of weave cycles of the intermediate layer C yarn weave. To obtain a honeycomb-shaped spacer fabric, the warp let-off of each layer of yarn needs to be the same.

In the embodiment, 50D/24F polyester yarn is selected for weaving, and 20 cycles are selected for weaving. The fabric surface density is: the density of the warp threads is 200 threads/5 cm, and the density of the transverse threads is 160 threads/5 cm. The woven product has the best effect.
