Problems solved by technology

Today, as more and more attention is paid to the appearance quality of products, the color difference between the left and right sides has become a major problem in the weaving of air-jet looms, which can only be compensated by adjusting the dyeing process, and cannot be fundamentally solved.

Embodiment Construction

[0010] Taking the actual production of the Suprem SPR-750 two-way air-jet loom as an example, the weaving variety is 2 / 1 right twill, the weaving warp and weft yarns are 30S yarns, the reed width is 174.8cm, and 8 sets of auxiliary nozzles are used, 4 in each set. To 32 auxiliary nozzles, a total of 64 auxiliary nozzles.

[0011] The starting and ending angles of weft insertion are 90° to 230°.

[0012] The arrangement of the auxiliary nozzles is as follows: the first group, the second group, the interval is 5cm, the third-sixth group, the interval is 7cm, and the seventh and eighth groups are 5cm apart. (The average interval is 6cm, which is the same as the setting of the auxiliary nozzle interval when weaving ordinary fabrics)

[0013] Set the working time of each auxiliary nozzle according to the direction of weft yarn travel:

[0014] The first group, 117-147 degrees; the second group, 136-166 degrees; the third group, 141-181 degrees; the fourth group, 155-195 degrees; ...

Abstract

The invention relates to a mounting method of auxiliary jets on an air-jet loom and a process parameter design method, particularly to a reasonable auxiliary jet arrangement and mounting method applicable to bidirectional weft insertion of the air-jet loom as well as determination of related weft insertion process parameters. The method is characterized in that during bidirectional weft insertion, the auxiliary jets are spaced in a small-large-small manner, and during weft insertion time parameter setting, the jetting time of the front-end auxiliary jet is shortened.

Description

technical field [0001] The present invention relates to an installation method and process parameter design method of an auxiliary nozzle of an air-jet loom, in particular to an adjustment of relevant process parameters of the auxiliary nozzle which is suitable for weft insertion of a two-way air-jet loom, and its goal is to ensure the smooth progress of weaving At the same time, save energy and reduce consumption as much as possible to reduce production costs. Background technique [0002] The air-jet loom uses the jet air as the carrier, and through the friction between the air and the yarn, the weft yarn is pulled through the shed to form a fabric. Its special weft insertion method makes it have the characteristics of high speed and high efficiency, and at the same time, it takes into account the wide variety of adaptability, which is an important direction for the development of shuttleless looms. In recent years, both foreign manufacturers and domestic loom manufacture...
