Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a triple / double vertical striped full-width warp-knitted fabric. Background Technology

[0002] Currently, the vast majority of full-width weft-lined warp-knitted fabrics on the market are warp-knitted fabrics with a full-width weft-lined chain knitting structure. Because the warp direction of the fabric is formed by the chain knitting threads, and the chain knitting structure itself has no elasticity, the warp elasticity of the fabric is very small. However, the extension length of the chain knitting thread is the smallest of all structures, so the chain knitting structure binds the weft yarns more tightly on the full-width weft-lined yarns than other warp-knitted structures. Therefore, the weft yarns of fabrics formed by full-width weft-lined chain knitting structures are woven more tightly than those of fabrics formed by full-width weft-lined warp knitting structures, making it difficult for the weft yarns to be pulled out. Furthermore, a single full-width weft-lined chain knitting structure fabric has a planar structure similar to woven fabric, with a stable structure and a lack of variation in appearance, appearing rather dull.

[0003] In a full-width plain weave fabric, the weft yarns are wedged between the loops and the extension lines of the needles in the plain weave. These extension lines are longer than those in a chain weave, so the weft yarns are not woven as tightly as in a chain weave. The weft yarns are more prone to snagging or being pulled out at the ends, requiring a very high longitudinal loop density (longitudinal density or similar to the weft density of woven fabrics) to weave the weft yarns tightly. Since a plain weave is a mesh structure that can deform in any direction, a full-width plain weave fabric tends to have elasticity in the warp direction, resulting in a uniform, flat appearance with poor layering. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a triple / double vertical striped full-width weft-lined warp-knitted fabric with excellent fabric structure stability, good breathability, and appropriate warp elasticity. By selecting the weft and warp yarns, the fabric's antibacterial properties and comfort can be guaranteed, making it suitable as a lightweight, soft, and comfortable linen-containing fabric for summer use.

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

[0006] A triple / double vertical stripe full-width weft-insertion warp-knitted fabric, which is formed by interweaving the filaments of one chain stitch guide bar with discontinuous periodic arrangement and the filaments of another tricot stitch with opposite symmetric discontinuous periodic arrangement on the linen-containing weft yarn of full-width weft insertion; the chain stitch is placed on the initial guide bar GB1, and the tricot stitch is placed on the second guide bar GB2, and in the periodic cycle of the chain stitch on GB1, the number of needles for continuous threading A is greater than the number of needles for continuous empty threading B, that is: A threading > B empty; and the number of needles for continuous empty threading B in the opposite arrangement order within the periodic cycle of the tricot stitch on GB2 is equal to the B empty in one cycle of the chain stitch on GB1, similarly, the number of needles A for continuous knitting of tricot loops in one cycle of GB2 is equal to the number of A threading in one cycle of the chain stitch on GB1, and it satisfies: B empty < A threading, and both A and B are natural numbers.

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

[0008] Preferably, the tricot stitch is a closed two-needle tricot stitch, and its pattern disc number is: GB2:12 / 10.

[0009] Preferably, when the stitch numbers of GB1 and GB2 are the same, and the number of needles for continuous A threading = 3 times the number of needles for continuous B empty threading, the full-width weft-insertion warp-knitted fabric with equal-distance double vertical stripes of the same stitch is knitted by the full-width weft-insertion warp-knitted structure with opposite threading and emptying sequence in the same cycle of the two guide bars, and its warp-knitted structure can be a chain stitch, a tricot stitch or other appearances. When producing warping of this two-guide-bar equal-distance vertical stripe full-width weft-insertion warp-knitted fabric, since the number of warp yarn ends on the two guide bar beams is exactly the same, it is the design method with the least waste of residual tail yarn during warping;

[0010] In other cases, it is a triple vertical stripe full-width weft-insertion warp-knitted fabric; when in each stitch cycle of the two guide bars, the number of needles for continuous A threading = 2 times the number of needles for B empty threading, the greige cloth appearance of the full-width weft-insertion warp-knitted fabric knitted by the two guide bars in an overlapping manner theoretically has equal-width vertical stripes of triple structure. However, in practice, due to the different warp knitting structures of the two guide bars, the mutual pulling between the loops on the same needle position of the weft yarn during warp yarn knitting may have a slight different left-right displacement, resulting in that the spacing of the triple vertical stripes is not absolutely the same in practice, which has nothing to do with the theoretical position of the stripes

[0011] Preferably, the machine gauge range of the fabric is E24-E32.

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

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

[0014] Preferably, the above-mentioned triple / double vertical striped full-width weft-lined warp-knitted fabric is woven by arranging two or three different materials or different elasticities of weft yarns at equal intervals and in equal numbers on a loom. After pre-shrinking, dyeing and finishing, etc., the weft yarns along the length direction will also form a triple / double horizontal stripe appearance. These will be superimposed and combined with the warp triple / double vertical stripes to form a checkered / wrinkled checkered fabric.

[0015] This invention provides a triple / double vertical striped full-width weft-lined warp-knitted fabric, which has the following advantages compared with the prior art:

[0016] This invention creates a full-width linen-weft-insulated fabric with triple / double vertical stripes, formed by weaving a pair of non-continuously periodically arranged chain-linked filaments together with another pair of oppositely symmetrically arranged, non-continuously periodically arranged warp-plain filaments onto a full-width linen-weft-insulated weft yarn. The specific weaving structure is as follows: Figure 1 As shown in the table below, the corresponding comb-joint yarn threading results in a fabric with excellent fabric structure stability, good breathability, and appropriate warp elasticity. By selecting the warp and weft yarns, good antibacterial properties and comfort can be achieved. It can be used as a duvet cover, bed sheet, pillowcase fabric, summer women's long dress, and men's shirt fabric, thus comprehensively enhancing the application value of the fabric.
