Problems solved by technology

The jacquard shedding mechanism can directly use the heddle to control the rise and fall of each warp thread, but the more the number of stitches, the higher the failure rate and cost of the equipment

Embodiment 1

[0028] Taking a typical product as an example, in the trial production test, the pattern manuscript adopts a width-to-height ratio of 1:1, and the warp thread material is made of all-polyester 75D / 36F beige DTY semi-glossy yarn, which is arranged on the upper warp beam and the lower warp beam according to 1:1. On the warp axis; the weft thread adopts a combination of 3 sets of wefts: 1 set (C weft) is the back interweaving weft, which is arranged on the lower layer of the fabric, and is interwoven with the lower warp beam warp with 8 pieces of 3 flying weft satin weaves; the other 2 According to the coloring needs of the pattern artist, the weft thread is used to develop the color of the jacquard with a weft double structure. In order to achieve a better shading effect, the weft thread (propylene weft) interwoven with the lower warp beam is made of 450D / 144F black polyester DTY filament, in order to highlight the three-dimensional and fullness of the weft pattern, and the other...

Embodiment 2

[0037] Taking a typical product as an example, in the trial production test, the width and height ratio of the pattern manuscript is 1:1.5, and the warp thread material is all polyester 75D / 36F beige DTY semi-glossy yarn, which is arranged on the upper warp beam and the lower warp beam according to 1:1. On the warp axis; the weft adopts a combination of 4 groups of wefts: 1 group (button weft) is the back weaving weft, which is arranged on the lower layer of the fabric, and is combined with the warp of the lower warp beam (inner warp) with 8 pieces of satin weave with 3 flying wefts Interweaving; the other three groups of weft threads are used to develop the color of the jacquard with a weft triple structure according to the coloring needs of the pattern artist. In order to achieve a better shading effect, the weft thread (button weft) interwoven with the lower warp beam is made of 450D / 144F black polyester DTY filament, in order to highlight the three-dimensional and fullness ...

Abstract

The invention relates to a method for producing a dobby-jacquard jointly-shedded multilayer jacquard fabric, which comprises the following steps in sequence: (a) designing the process specifications; (b) designing the artistic conception; (c) designing the organizational structure; (d) generating a pattern card; and (e) weaving by using a machine. In the step (a), a double-warp-shaft weaving machine which comprises an upper warp shaft and a lower warp shaft is used for weaving two or more groups of warp yarn, and the warp yarn on the upper warp shaft and the warp yarn on the lower warp shaft are arrayed in sequence at the same amount on the double-warp-shaft weaving machine. In the step (c), two shedding controlling mechanisms including a jacquard shedding controlling mechanism and a dobby shedding controlling mechanism are used for designing the organizational structure independently and combining in the weaving process. In the step (e), 8 to 16 heald frames are used for controlling the warp yarn of the lower warp shaft in the process of weaving of the double-warp-shaft weaving machine, and the jacquard weave information is inputted into a jacquard head. Due to the adoption of the method, the multilayer jacquard fabric with high warp and weft density, good shading performance and different usual jacquard effects on two sides can be woven.

Description

【Technical field】 [0001] The invention relates to a method for making a multi-layer jacquard fabric, in particular to a method for making a high-density multi-layer jacquard fabric with combined openings of dobby and jacquard. 【Background technique】 [0002] The dobby shedding mechanism can be used to weave complex small pattern fabrics. At present, the heald frames of the dobby loom can reach up to 32 pages. However, the more the number of heald frames, the greater the warp tension difference between the front and rear healds of the loom, the higher the opening height of the front healds, the lower the loom’s operating efficiency and the higher the energy consumption. Therefore, the dobby loom should not use too many heald frames, and it is generally controlled within 16 heald frames. The jacquard opening mechanism can directly use the heddle to control the lifting of each warp thread, but the more the number of stitches, the higher the failure rate and cost of the equipme...
