Problems solved by technology

However, in order to adapt to the changing speed requirements of modern varieties, it is obvious that simply changing the hanging method of the jacquard machine heddle or changing the size of the needle position of the faucet will still be greatly affected in terms of production efficiency, production process, production cost and pattern layout. limit

Embodiment 1

[0061] Example 1 (when the fixed full wear machine does not change)

[0062] Fixed warp density on the machine: 110 threads / cm;

[0063] Weft shrinkage=4%;

[0064] Number of needles in a pattern (n) = 1200 (needles);

[0065] The first 600 stitches of weave are 5 pieces of weft satin, and the last 600 stitches are 5 pieces of warp satin;

[0066] Then the maximum size of the single cycle return on the machine can only be: (1200 / 110 / cm) / (1+0.04)=10.5cm.

Embodiment 2

[0067] Embodiment 2 (when the heald adopts 1 thread and 1 hole)

[0068] Warp density on the machine: 55 threads / cm;

[0069] Weft shrinkage=4%;

[0070] Number of needles in a pattern (n) = 1200 (needles);

[0071] The first 600 stitches are 5 pieces of weft satin, and the last 600 stitches are 5 pieces of warp and satin. Move the first 600 stitches of weft satin to odd-numbered needles, and the last 600 stitches of warp and satin to even-numbered needles. Thread on odd-numbered needles, and even-numbered flower healds on the machine on even-numbered needles;

[0072] Then the maximum size of the single cycle return on the machine is: (1200 / 55 / cm) / (1+0.04)=21cm.

Embodiment 3

[0073] Embodiment 3 (the heddle adopts positioning to wear)

[0074] Weft shrinkage=4%

[0075] Number of needles for one pattern (n) = 1200 (needles), a total of 6 times on the machine;

[0076] The total width of heald full wear is: (1200 / 110 / cm) X13 / (1 + 0.04) = 136.5 cm; the maximum return position can only be (1200 / 110 / cm) / (1 + 0.04) =10.5 cm.

[0077] Now change the warp line density on the machine to: 55 wires / cm;

[0078] The first 600 stitches and the last 600 stitches are 5 pieces of weft satin, and the middle 6600 stitches are 5 pieces of warp satin. Move the first 600 stitches of weft satin to the odd-numbered needles, and move the last 600 stitches of warp satin to the even-numbered needles. The 1st and 13th flower healds on the machine are threaded on even-numbered needles, and the 2nd to 12th flower healds on the machine are threaded on even-numbered needles;

[0079] Then the maximum size of the single cycle return position on the machine become...

Abstract

The invention relates to a method for producing variable cycle fabrics using a fixed jacquard manufacturing process, which includes the following process steps: (1) process specification design; (2) pattern design; (3) laying structure; plate. The present invention uses different needle positions of the faucet on the basis of the original fixed warp density, and can regularly change the warp density of the warp, and then achieve different changes in fabrics through the thickness ratio of the warp and the selection of different weave configurations. Effect. With this method, there is no need to carry out the heald hanging process, and the warp heald is selectively threaded and the electronic pattern generation method is adopted. The pattern can be directly processed at the specific position in the machine width, which realizes the expansion of the cycle and avoids the pattern design. Due to size requirements, it is necessary to continuously change machines, heddle hoisting methods, and plank arrangement and other complex installations.

Description

[0001] 【Technical field】 [0002] The invention relates to a fabric production method, in particular to a method for producing variable cycle fabrics using a fixed jacquard manufacturing process, and belongs to the technical field of jacquard fabric production techniques. [0003] 【Background technique】 [0004] The weaving industry is a traditional industry in China, and jacquard fabric is a common and unique weaving method in traditional crafts. The basic appearance of the fabric is to use colorful warp and weft threads to form specific patterns and patterns. , the pattern or pattern has obvious three-dimensional linear effect, and the change of pattern changes regularly with the size of the jacquard machine faucet, which has good decoration and aesthetic feeling. To change the traditional jacquard machine manufacturing process, the production time is long and the production cost is high. [0005] With the development of the times, people have higher and higher requirements ...
