Embodiment 1

[0017] like Figure 1 to Figure 3 Shown:

[0018] The purpose is to figure 1 The original pattern shown is the small pattern of 1.2.3.4.5.6.7.8.9.10.11.12 (a total of 12 numbers indicates that the small pattern is composed of 12 warp yarns and 12 weft yarns) and is proportionally enlarged by 5 times the side length , 25 times the area, ie N=M=5.

[0019] like image 3 As shown, the specific method is to group 5 warp yarns into a group, and the rules of wearing brown in each group are: 1.2.3.4.5, 2.3.4.5.6, 3.4.5.6.7, 4.5.6.7.8, 5.6.7.8. 9, 6.7.8.9.10, 7.8.9.10.11, 8.9.10.11.12, 9.10.11.12.1, 10.11.12.1.2, 11.12.1.2.3, 12.1.2.3.4, thus completing a cycle; 1 represents the first frame brown silk, 2 represents the second frame brown silk, and so on, 12 represents the twelfth frame brown silk. The number of numbers indicates the number of warp yarns, and 60 warp yarns are used here, so the warp direction of the small pattern is enlarged by 5 times. The puncture (brown) numbe...

Embodiment 2

[0024] like figure 1 , Figure 4 and Figure 5 Shown:

[0025] The purpose is to enlarge the small pattern of the original flower type 1.2.3.4.5.6.7.8.9.10.11.12 in the warp direction by 5 times, in the weft direction by 3 times, and in the area by 15 times, that is, N=5, M= 3.

[0026] The specific method is to make a group of 5 warp yarns, and the rule of wearing brown in each group is: 1.2.3.4.5, 2.3.4.5.6, 3.4.5.6.7, 4.5.6.7.8, 5.6.7.8.9, 6.7 .8.9.10, 7.8.9.10.11, 8.9.10.11.12, 9.10.11.12.1, 10.11.12.1.2, 11.12.1.2.3, 12.1.2.3.4, complete a cycle; where 1 means the first Frame brown silk, 2 represents the second frame brown silk, and so on, 12 represents the twelfth frame brown silk. The number of numbers indicates the number of warp yarns, and 60 warp yarns are used here, so the warp direction of the small pattern is enlarged by 5 times. The puncture (brown) numbers on the expanded organization effect chart are extended and enlarged by the method of "taking five int...

Abstract

The invention provides a method for producing a jacquard-like pattern with a dobby loom. With an original small pattern as a chief source, the method makes progressive combination in a warp-wise arrangement order of original yarn, i.e. advancing a digit number when every N digits are taken, step by step in an orderly way until the end of a cycle, with the N as an amplification factor in the warp direction; meanwhile, progressive combination is conducted in a broadwise arrangement order of the original yarn, i.e. advancing a digit number when every M digits are taken, step by step in an orderly way until the end of a cycle, with the M as an amplification factor broadwise; the produced jacquard-like pattern is N*M times of the original small pattern in area. With both low cost and high efficiency, the method of the invention solves the problem of producing jacquard fabrics on a dobby loom, and also can produce jacquard patterns of different effects.

Description

【Technical field】 [0001] The invention relates to a fabric weaving method, in particular to a method for producing jacquard imitation patterns by using a dobby loom. 【Background technique】 [0002] The dobby loom in the textile industry is the main equipment for producing fabrics with small patterns at present. , can only be limited to 24 sequences at most, and the changes are limited, which seriously limits the expansion of the pattern and limits the pattern to a small range. Therefore, producing jacquard fabrics with dobby looms is a problem that has perplexed the textile industry for many years, making jacquard fabrics a high-end product for clothing and home textile fabrics. [0003] Later, a jacquard loom that can produce jacquard fabrics appeared in the industry. It uses steel needles instead of the heald frame of the dobby machine to lift the thread, which can be infinitely increased to more than 1,000 needles, that is to say, each needle can Independently control t...
