Method for producing large circulation jacquard fabric using dobby machine

Abstract

The invention discloses a method for producing large circulation jacquard fabric using a dobby machine comprising following steps: reconstruction of a dobby machine: a machine control system main board is added, two groups of EEPROM, IC2 and IC3 are added to the main board to form a series connection with IC1 in the early jacquard card; (2) large jacquard pattern design: N-40 / 34FDFDY is selected as warp yarn and N-40 / 34FDFDY is selected as weft yarn, wherein the specification on machine is: the total ends in warp is 11184, 55.9plumage / in, 3 in / plumage, the width on machine is 66.69in, the weft density on machine is 165T / in; a basic structure is selected, and 1 to 12 pages straight draft is adopted; the patterns are amplified transversely, then the patterns are amplified vertically, and five-equal partition into one is used for amplifying the jacquard cards sequentially; (3) pattern combination: the patterns in the basic structure are combined again and gradually changed patterns are designed. The method of the invention overcomes the bottleneck of producing large circulation jacquard fabric by common dobby machines, which has high production efficiency.

Description

technical field [0001] The invention relates to the field of fabric weaving, in particular to a method for producing large-cycle jacquard fabrics with an ordinary electronic dobby. Background technique [0002] As we all know, the use of jacquard machines to produce large-circle jacquard fabrics has the following disadvantages: First, the production efficiency is low, because the jacquard machines use a large number of hanging palms. Generally, the weaving speed is low, with an average of 300 rpm. Second, the cost of fabrics produced is relatively high, first of all, the cost of hardware is relatively high, and secondly, because the weaving efficiency is very low, the production cost is relatively high, which is not conducive to a large number of popularization, especially for fine denier and high-density products, the production cost of large jacquard machines Higher; the jacquard machine on the market charges 0.25 yuan / shuttle, and the weaving cost per meter is 16.5 yuan ...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a method for producing large-cycle jacquard fabrics with a dobby loom, which overcomes the bottleneck in the production of large-cycle jacquard fabrics by ordinary dobby looms, mainly because the number of cycles of a single plate is not enough, and the usual The upper limit of a single cycle of the machine is 999 times, which is far below the requirements of a single cycle required by a single garment; secondly, the problem of weaving efficiency is solved, and the production of ordinary dobby looms avoids the low efficiency of jacquard weaving The problem
