Problems solved by technology

[0002] At present, carbon fiber unidirectional fabrics on the market are generally produced by weaving (flat and twill) processes. Carbon fiber unidirectional fabrics produced by woven processes have buckling of carbon fibers in the 0° direction, poor fabric stability, easy fluffing of fibers, and large loss of fiber properties. The road processability is poor, and the performance of the workpiece is also poor

Embodiment 1

[0020] Such as figure 1 Shown, a kind of carbon fiber warp-knitted unidirectional fabric production process comprises the following steps: warping and upper shafting of binding thread 3, yarn laying of glass fiber weft yarn 2, and carbon fiber warp yarn 1 is combined with after fiber spreading, warping and upper shafting The glass fiber weft yarn 2 is woven together with the binding thread 3, and then the woven cloth is cut, rolled and packaged.

[0021] Such as figure 2 As shown, in the weaving process, the binding wire 3 moves according to the following rules:

[0022] a. In the first course, the binding thread 3 moves to the left or right by a needle distance L2 while moving one course L1 in the warp direction. The needle distance L2 is smaller than the width of the carbon fiber warp yarn 1, and then passes through the carbon fiber warp yarn 10% lock up;

[0023] b. In the second row, the binding thread 3 warp moves a row L1, and then passes through the carbon fiber war...

Embodiment 2

[0032] The production process of C-L200 carbon fiber warp knitted fabric.

[0033] 1. Raw material preparation

[0034] The raw material selects polyester low elastic yarn (polyester fiber) as the binding thread 3, carbon fiber as the warp yarn 1, and glass fiber spun yarn 2 as the weft yarn.

[0035] The specification of polyester low elastic yarn (polyester fiber) is 3.3 tex, the specification of carbon fiber is 12K, and the specification of weft yarn is 68 tex.

[0036] 2. Warping

[0037] Qualified polyester low-elastic yarns are warped, and the yarn threading sequence is tension disc, porcelain eye, tension porcelain plug, transmission arm porcelain ring, yarn support rod porcelain eye, yarn broken automatic stop, contact eyelet, and yarn collecting plate porcelain eye , splitting needle, tension roller, wool instrument, splitting needle, storage splitting needle, oiler, herringbone reed splitting needle, and the pan head is wound into a pan head with 125 heads and a le...

Embodiment 3

[0047] The production process of producing C-L400 carbon fiber warp knitted fabric.

[0048] 1. Raw material preparation

[0049] The raw material selects polyester low elastic yarn (polyester fiber) as the binding thread 3, carbon fiber as the warp yarn, and glass fiber spun yarn as the weft yarn.

[0050] The specification of polyester low elastic yarn (polyester fiber) is 3.3 tex, the specification of carbon fiber is 24K, and the specification of weft yarn is 68 tex.

[0051] 2. Warping

[0052] The warping of the binding wire 3 is the same as in Embodiment 1.

[0053] Qualified carbon fibers are warped, and the yarn threading sequence is guide roller, yarn positioner, each guide roller, heating fiber spreading device, mechanical fiber spreading device, splitting needles with a spacing of 8.4 mm, and winding head, The pan head is rolled into 18 parts, the yarn width is 24 mm, and the 800-meter-long carbon fiber pan head enters the warp knitting process after passing the ...

Abstract

The invention discloses a production process of carbon fiber warp-knitting unidirectional cloth, comprising the following steps: warping and shaft-arranging a binding line 3; laying glass fiber weft 2; spreading, warping and shaft-arranging carbon fiber warp 1 to weave with the binding line 3 together; and finally cutting, rolling and packaging the weaved cloth. The textile fiber produced by the process has no bending, good stability and good properties.

Description

technical field [0001] The invention relates to a unidirectional cloth production process, in particular to a unidirectional cloth production process with carbon fiber as a raw material. Background technique [0002] At present, carbon fiber unidirectional fabrics on the market are generally produced by weaving (flat and twill) processes. Carbon fiber unidirectional fabrics produced by woven processes have buckling of carbon fibers in the 0° direction, poor fabric stability, easy fluffing of fibers, and large loss of fiber properties. The road processability is poor, and the performance of the workpiece is also poor. Contents of the invention [0003] The purpose of the present invention is to provide a production process of a carbon fiber warp-knitted unidirectional fabric with no bending of fabric fibers, good stability and good performance. [0004] The technical solution for realizing the above-mentioned invention is a production process of carbon fiber warp-knitted u...
