Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a triple / double vertical striped full-width weft-inserted warp knitted fabric. Background Art

[0002] At present, most of the full-width weft-inserted warp knitted fabrics on the market are full-width weft-inserted chain knitted fabrics. Since the warp direction of the fabric is composed of the warp yarns of the chain knitted fabric, and the chain knitted fabric itself has no elasticity, the warp elasticity of the fabric is very small. However, the extension length of the chain knitted fabric is the smallest among all fabrics, so the chain knitted fabric is woven on the full-width weft yarn and the weft yarns are tied tighter than other warp knitted fabrics. Therefore, the weft yarns of the fabric formed by the full-width weft-inserted chain knitted fabric are woven tighter than the weft yarns of other full-width weft-inserted warp knitted fabrics, so the weft yarns of the fabric formed by the full-width weft-inserted chain knitted fabric are not easy to be pulled out. Moreover, the single full-width weft-inserted chain knitted fabric is a planar structure similar to a woven fabric, with a stable structure and a lack of changes in appearance, which looks relatively dull.

[0003] The weft yarn of the full-width weft-inserted warp plain fabric is inserted between the circle column of the warp plain fabric and the extension line of the needle-to-needle lateral movement. Its extension line is longer than that of the chain weave, so the weft yarn is not woven as tightly as the chain weave. The weft yarn is easy to be hooked or pulled out on the end surface. A very high longitudinal coil density (longitudinal density or similar weft density of woven fabric) is required to weave the weft yarn tightly. The warp plain fabric is a mesh structure that can be deformed in any direction, so the full-width weft-inserted warp plain fabric is easy to be elastic in the warp direction, and the appearance is also a uniform single plane, with a poor sense of hierarchy. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a triple / double vertical striped full-width weft-inserted warp knitted fabric, which has good fabric structure stability, good air permeability, and appropriate warp elasticity. The antibacterial property and comfort of the fabric can be ensured through the selection of weft yarn and warp yarn. The fabric is suitable as a light, soft, and comfortable linen-containing fabric for use in summer.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented through the following technical solutions:

[0006] A triple / double vertical stripe full-width weft-inserted warp knitted fabric is formed by knitting a filament of a chain stitch with a non-continuous periodic arrangement and a filament of a plain stitch with an opposite symmetric non-continuous periodic arrangement together on a full-width weft-inserted linen weft yarn; the chain stitch is placed on the starting comb GB1, and the plain stitch is placed on the second comb GB2, and the number of continuously threaded needles A in one cycle of the GB1 chain stitch is greater than the number of continuously empty needles B, that is: A > B; and the number of continuously empty needles B with opposite arrangement order in one cycle of the GB2 plain stitch is equal to B in one cycle of the GB1 chain stitch. Similarly, the number of needles A that continuously knit plain stitch loops in one cycle of GB2 is equal to the number of A in one cycle of the GB1 chain stitch, and it satisfies: B < A, and both A and B are natural numbers.

[0007] Preferably, the chain stitch is a closed chain stitch, and its cam disk number is: GB1: 10 / 10.

[0008] Preferably, the plain stitch is a closed two-needle plain stitch, and its cam disk number is: GB2: 12 / 10.

[0009] Preferably, when the organization numbers of GB1 and GB2 are the same, and the number of continuously threaded needles A = 3 times the number of continuously empty needles B, a full-width weft-inserted warp knitted fabric with the same organization and equidistant double vertical stripes is knitted by the full-width weft-inserted warp knitted organization with opposite threading and emptying orders in the same cycle of the two combs. Its warp knitted organization can be a chain stitch or a plain stitch appearance. When producing warping for this two-comb equidistant vertical stripe full-width weft-inserted warp knitted fabric, since the number of warp yarn head patterns on the bobbins of the two combs is exactly the same, it is the design method with the least waste of the remaining tail yarn during warping;

[0010] In other cases, it is a triple vertical stripe full-width weft-inserted warp knitted fabric; when the number of continuously threaded needles A = 2 times the number of empty needles B in each organization cycle of the two combs, the triple organization vertical stripe appearance of the full-width weft-inserted warp knitted fabric blank knitted by overlapping the two combs is theoretically of equal width. However, in reality, due to the different warp knitting organizations of the two combs, there may be slightly different left and right displacements due to the mutual pulling between the loops at the same needle position of the warp yarns during knitting, resulting in the actual triple vertical stripe spacing not being absolutely the same, which has nothing to do with the theoretical position of the stripes

[0011] Preferably, the needle density range of the fabric is E24 - E32.

[0012] Preferably, the warp yarn material of the fabric is PA or PET material, and the fineness specification range is 30D - 75D filament.

[0013] Preferably, the weft yarn of the fabric is any one of linen yarn containing 15-100% linen, cotton and linen blended yarn, viscose and linen blended yarn, low-temperature dyed polyester and linen blended yarn, and linen core-spun yarn with shrinkable filament as core yarn, and the hemp component is any one or more of hemp, flax or ramie; and the thickness range of the weft yarn is 10-32S, and the weft density range during weaving is 10-30 strands / cm.

[0014] Preferably, the weft yarns of the above-mentioned triple / double vertical striped full-width weft-inserted warp knitted fabric are arranged on a loom with two or three weft yarns of different materials or different elasticities arranged equidistantly and in equal numbers to form a grey cloth, and after post-processing such as pre-shrinking, dyeing and finishing, the weft yarns along the length direction will also form a triple / double horizontal striped appearance, which are superimposed and combined with the triple / double vertical stripes in the warp direction to form a fabric with a checkered / wrinkled checkered appearance.

[0015] The present invention provides a triple / double vertical stripe full-width weft-inserted warp knitted fabric, which has the following advantages over the prior art:

[0016] The present invention is a full-width weft-inserted linen fabric with triple / double vertical stripes periodically arranged on the full-width weft-inserted linen weft yarn, formed by weaving a pair of filaments of a chain-weave structure combed in a non-continuous periodic arrangement with another pair of filaments of a warp-weave structure arranged in an opposite and symmetrical manner. The specific weaving structure is as follows: Figure 1 The corresponding combing yarn is shown in the following ratio table. The obtained fabric has good fabric structure stability, good air permeability, and appropriate warp elasticity. Through the selection of warp and weft yarns, good antibacterial and comfort can be achieved. It can be used as quilt covers, bed sheets, pillowcases, summer women's long skirts, and men's shirts, which comprehensively improves the application value of the fabric.
