Description

Technical Field

[0001] The invention relates to the technical field of full-width weft-inserted warp knitting structures, in particular to a double-comb full-width weft-inserted warp knitted vertical striped linen fabric. Background Art

[0002] Warp knitted fabrics with full weft insertion will have their own characteristics due to the insertion of weft yarns with different structures and properties. Weft yarns with very low stretchability can be used to increase the stability of the fabric structure and size, which is similar to woven fabrics; weft yarns with great stretchability and elasticity can also be used to weave elastic fabrics with two-way stretch. When using colored weft yarns and selective full weft insertion, it is very easy to weave clear horizontal stripes that are difficult to weave with ordinary warp knitting. In addition, using poor quality yarns, uneven short fiber yarns, knot yarns and other fancy yarns and very thick yarns that are difficult to weave with ordinary warp knitting machines as weft yarns, and then configuring them with intermittent or selectively changing weft insertion, fabrics with unique styles and effects can be obtained. Therefore, it has been very popular with consumers for many years and is widely used in bed sheets, burnt-out decorative fabrics, structural curtains, lining fabrics, men's and women's outerwear fabrics and industrial fabrics.

[0003] Linen yarn is a yarn made from natural plant fibers. Linen fabrics woven from linen yarn generally have good air permeability and sweat absorption, but the overall feel of full-linen fabrics is poor. Using full-width weft warp knitting technology to prepare linen fabrics can effectively improve the feel of linen fabrics. However, the fabrics woven with traditional full-width weft warp knitting technology are generally medium-thick, which is overall thick for a material like linen yarn, causing the fabric to become hard and reducing softness and air permeability. Therefore, it is necessary to combine the characteristics of linen yarn and use full-width weft warp knitting technology to design a new linen fabric to meet market demand. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a double-combed full-width weft-inserted warp-knitted vertical striped linen fabric, which adopts chemical fiber filaments and linen yarn to prepare the full-width weft-inserted warp-knitted structure, so as to achieve high air permeability, antibacterial, moisture absorption and perspiration wicking effects of the fabric, and ensure the lightness and comfort of the fabric.

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

[0006] A double-comb full-width weft-inserted warp-knitted vertical striped linen fabric, wherein the double-comb full-width weft-inserted warp-knitted vertical striped linen fabric is formed by overlapping the chains of two-comb warp chain organizations, alternating single chains and empty threads, and full-width weft-inserted weft yarns to form vertical stripe patterns on the fabric surface.

[0007] Preferably, the two comb sections are GB1 comb section and GB2 comb section, wherein the warp yarn arrangement and threading rule on the yarn guide needle of GB1 comb section is 3 threads + empty + thread + empty + 6 threads + 6 empty / / 18 needle positions for one cycle; the warp yarn arrangement and threading rule on the yarn guide needle of GB2 comb section is 6 empty + 6 threads + empty + thread + empty + 3 threads / / 18 needle positions for one cycle.

[0008] Preferably, the full-width weft insertion warp knitting machine used for the double-comb full-width weft insertion warp knitted vertical striped linen fabric has a needle density range of E24-E32.

[0009] Preferably, the material of the warp of the double-comb full-width weft-inserted warp-knitted vertical striped linen fabric is PET or PA, and the thickness specification range is 20D-50D filament.

[0010] Preferably, the weft yarn of the double-combed full-width weft-inserted warp-knitted vertical striped linen fabric is any one of linen yarn containing 15-100% linen, cotton and linen blended yarn, viscose and linen blended yarn, polyester and linen blended yarn, blended yarn of three types of linen fibers, and linen core-spun yarn, and the linen component is any one or more of hemp, flax or ramie.

[0011] Preferably, the hemp-containing core-spun yarn is a core-spun yarn with a ratio of 85 / 15 viscose and hemp or a ratio of staple fiber.

[0012] Preferably, the thickness of the weft yarn of the double-comb full-width weft-inserted vertical striped linen fabric ranges from 12S to 32S.

[0013] Preferably, the weft density range of the double-comb full-width weft-inserted warp-knitted vertical striped linen fabric during weaving is 14-30 threads / cm.

[0014] The present invention provides a double-comb full-width weft-inserted warp-knitted vertical striped linen fabric, which has the following advantages compared with the prior art:

[0015] The organizational structure of the fabric prepared by the present invention, the raw materials of the warp and weft yarns, and the products woven from the warp and weft densely have good air permeability and anti-moiré characteristics, and at the same time, the dry, breathable and light effects of the fabric are achieved through reasonable deterioration, and the antibacterial, deodorizing, moisture absorption and perspiration effects of the fabric are further guaranteed in combination with the characteristics of the linen material, and the weft elasticity is guaranteed, thereby expanding the use of the fabric and improving the market value.
