Description

Technical Field

[0001] This invention relates to weft-patterned fabrics, and more particularly to a method for weaving double-sided weft-patterned fabrics on a double-shuttle loom, belonging to the field of textile technology. Background Technology

[0002] Jacquard fabrics generally come in two types: warp-laid and weft-laid. Warp-laid fabrics have higher production volumes and are relatively lightweight, thus having a wider market. Weft-laid fabrics, on the other hand, have lower production volumes and are relatively thicker, but they also have a certain market share, each offering its own unique characteristics and enriching the market. Currently, existing double-shed looms are primarily used for weaving velvet fabrics, spacer fabrics, and the like. However, velvet and spacer fabrics are subject to seasonality; during peak seasons, overtime work is required, while during off-peak seasons, inventory cannot be maintained, and production must be halted. However, our company had a sudden inspiration: if we used double-shed looms to weave double-sided weft-laid fabrics, it would not only balance the production time of double-shed looms, allowing them to operate year-round, but also enable the development of several entirely new weft-laid fabrics. Summary of the Invention

[0003] The purpose of this invention is to provide a method for weaving double-sided weft-patterned fabric on a double-shed loom. No modifications are made to the double-shed loom itself; the invention simply breaks away from the traditional concept of weaving only velvet and spacer fabric on a double-shed loom and introduces a new weaving method. As a result, a fabric with weft-patterned patterns on both sides of a single-layer base fabric and a method for weaving double-sided weft-patterned fabric have been developed.

[0004] To solve the above-mentioned technical problems, the objective of this invention is achieved as follows:

[0005] The present invention relates to a method for weaving a double-sided weft-patterned fabric on a double-shed loom, wherein the double-sided weft-patterned fabric includes a base fabric and an upper surface weft pattern portion and a lower surface weft-patterned portion located on both sides of the base fabric.

[0006] The base fabric is woven from base fabric warp yarns and base fabric weft yarns. The base fabric warp yarns are divided into tight warp yarns and loose warp yarns, arranged in a 1:1 ratio. The base fabric weft yarns are further divided into upper ground weft yarns and lower ground weft yarns.

[0007] The upper surface weft pattern is formed by interlacing the upper surface warp yarns and the upper surface weft yarns.

[0008] The lower surface weft pattern is formed by interlacing the lower surface warp yarns and the lower surface weft yarns.

[0009] Furthermore, all the warp yarns are arranged in a cycle of one tight warp yarn, one loose warp yarn, one upper surface warp yarn, and one lower surface warp yarn as a unit.

[0010] Furthermore, all the weft yarns are arranged in a cycle of 1 upper base fabric weft yarn, 2 upper surface weft yarns, 2 lower surface weft yarns, and 1 lower base fabric weft yarn as a unit.

[0011] The method specifically includes the following steps:

[0012] Step 1, warping: Warp the tight ground warp yarns in sequence onto one warp beam; warp the loose ground warp yarns in sequence onto another warp beam; the tight-to-loose ratio of the tight warp yarns is 1:0.85.

[0013] The upper and lower warp yarns are warped in sequence and placed on a single warp beam.

[0014] Step 2, threading the heddles: Arrange all the warp yarns in a cycle of 1 tight warp yarn, 1 loose warp yarn, 1 upper surface warp yarn, and 1 lower surface warp yarn, and thread them into the pile warp heddles of the double shed loom in sequence, and insert them into the reed teeth according to the set warp yarn density.

[0015] Step 3: Adjusting the weft insertion and hedging:

[0016] 3.1 Base Fabric Weaving: The base fabric is woven from ground warp yarns and upper and lower ground weft yarns. Furthermore, all tight warp yarns in the ground warp are below all upper weft yarns and above all lower weft yarns, separating the upper and lower weft yarns. The tight warp yarns are woven in a cyclical pattern in the healdrying sequence on the double-shed loom, always in the middle position. The loose warp yarns, in turn, are woven sequentially: first above the first upper base fabric weft yarn, then below the two upper surface weft yarns, then above the two lower surface weft yarns, and finally below the first lower base fabric weft yarn. The loose warp yarns are woven in a cyclical pattern in the healdrying sequence on the double-shed loom, in an upper-middle-lower position. This creates a three-upper-three-lower weave structure for the tight warp yarns and one-downper-upper-lower ...

[0017] 3.2 Simultaneously, the upper surface weft pattern is woven in sync: the upper rapier of the double-shed loom feeds the two upper surface weft yarns and the upper surface warp yarns to weave the upper surface weft pattern according to the weft pattern design.

[0018] 3.3 Simultaneously, the lower surface weft pattern is woven in sync: the lower rapier of the double shed loom feeds the two lower surface weft yarns and the lower surface warp yarns to weave the lower surface weft pattern according to the weft pattern design.

[0019] Step 4: Post-processing.

[0020] Based on the above scheme and as a preferred option: in the base fabric weaving, the tight warp yarns can also be woven in a one-up-one-down cycle between the upper and lower weft yarns, and the loose warp yarns can be interwoven in a three-up-three-down, four-up-four-down, or five-up-five-down pattern between the upper and lower weft yarns, so as to increase the flexibility of weft pattern weaving in the upper and lower surface layers.

[0021] The beneficial effects of this invention are as follows: The method for weaving double-sided weft-patterned fabric on a double-shed loom not only broadens the range of fabric types that can be woven on a double-shed loom, but also breaks through the cross-border weaving from velvet and spacer fabrics to plain weave fabrics and then to double-sided weft-patterned fabrics. This method is highly welcomed by weaving factories that own double-shed looms, and it also innovates weft-patterned fabrics. A fabric with weft-patterned patterns on both the upper and lower surfaces will make the weft-patterned fabric have no right or wrong sides, and the upper and lower surfaces can have different patterns and colors. It can be said to be a completely new weft-patterned product, not only without right or wrong sides, but also with a strong three-dimensional effect. Attached Figure Description

The present invention relates to a method for weaving a double-sided weft-patterned fabric on a double-shed loom, wherein the double-sided weft-patterned fabric includes a base fabric and an upper surface weft pattern portion A+ and a lower surface weft-patterned portion B+ located on both sides of the base fabric.

[0027] The base fabric is woven from ground warp yarns and ground weft yarns, the ground weft yarns include upper ground weft yarns and lower ground weft yarns, the upper surface weft pattern part is woven from upper surface warp yarns and upper surface weft pattern weft yarns, and the lower surface weft pattern part is woven from lower surface warp yarns and lower surface weft yarns.

[0028] The method specifically includes the following steps:

[0029] Step 1, warping: Warp the tight ground warp yarns in sequence onto one warp beam; warp the loose ground warp yarns in sequence onto another warp beam; the tight-to-loose ratio of the tight warp yarns is 10:0.85.

[0030] Arrange the top and bottom warp yarns in sequence on a single warp beam.

[0031] Step 2, threading the heddles: Arrange all the warp yarns in a cycle of 1 tight warp yarn, 1 loose warp yarn, 1 top face warp yarn, and 1 bottom face warp yarn, and thread them into the pile warp heddles of the double shed loom in sequence, and insert them into the reed teeth according to the set warp yarn density.

[0032] Step 3: Adjusting the weft insertion and hedging:

[0033] 3.1 Base Fabric Weaving: The base fabric is woven from ground warp yarns and upper and lower ground weft yarns. Further, in the ground warp yarns, all tight warp yarns are below all upper weft yarns and above all lower weft yarns, separating the upper and lower weft yarns. The tight warp yarns are woven in a cyclical pattern in the healdrying sequence on the double-shed loom, while the loose warp yarns are woven in a cyclical pattern, first above the first upper base fabric weft yarn, then below the two upper surface weft yarns, then above the two lower surface weft yarns, and finally below the first lower base fabric weft yarn. The loose warp yarns are woven in a cyclical pattern in the healdrying sequence on the double-shed loom, always in an upper-middle-lower position. This creates a three-upper-three-lower weave structure relative to all weft yarns, with tight warp yarns one-upper and loose warp yarns one-lower.

[0034] 3.2 Simultaneous weft-start pattern weaving on the upper surface: On the double-shed loom, the upper rapier feeds the two upper surface weft yarns and the upper surface warp yarns to weave the upper surface weft-start pattern according to the weft-start pattern design.

[0035] 3.3 Simultaneous weft-start pattern weaving of the lower surface layer: The lower rapier of the double-shed loom feeds the two lower surface layer weft yarns and the lower surface layer warp yarns to weave the lower surface layer weft-start pattern according to the weft-start pattern design.

[0036] In this embodiment, the patterns of the upper and lower weft-started floral sections can be selected according to actual needs; they can be the same or different.

[0037] Step 4: Post-processing.

[0038] Based on the above scheme and as a preferred option: in the base fabric weaving, the tight warp yarns can also be woven in a one-up-one-down cycle between the upper and lower weft yarns, and the loose warp yarns can be interwoven in a three-up-three-down, four-up-four-down, or five-up-five-down pattern between the upper and lower weft yarns, so as to increase the flexibility of weft pattern weaving in the upper and lower surface layers.

[0039] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
