Production method for air jet loom weaving multicolored weft fabric

Abstract

The invention relates to a production method for air jet loom weaving a multicolored weft fabric and at most 16 barry dyeing of the fabric can be achieved. The fabric is a special fabric developed by a Surprise bidirectional wefting insection loom. An air jet bidirectional wefting insection technology is employed; at most eight barrye dyed weft yarns can be inserted for each side; and at most 16 barry dyed yarns can be achieved for two sides. Deficiencies of poor multicolored barry dyeing performance and difficulty in type rennovation by the present air inject wefting insertion technology can be solved to some extent; and air jet weaving type ranges can be enlarged.

Description

technical field [0001] The invention relates to an air-jet loom for weaving multi-color weft fabrics, which can realize up to 16 color wefts. This fabric is a special fabric developed based on Suplan bi-directional weft insertion loom. The fabric adopts air-jet two-way weft insertion, and each side can use up to 8 different color weft insertions, and up to 16 different color wefts can be inserted on both sides. Background technique [0002] Due to its high speed, high output, and wide range of adaptability, air-jet looms currently occupy the mainstream in the production and processing of woven fabrics. The air-jet loom inserts the weft through the airflow, and through the joint action of the main nozzle and the relay nozzle, the yarn is introduced into the weaving fell to form a fabric. [0003] In order to ensure the effective traction of the airflow during the weft insertion process of the air-jet loom, it is necessary to use a special-shaped reed to ensure that the weft...

AI Technical Summary

Problems solved by technology

The size of the weft insertion channel of the profiled reed stroke needs to meet the requirements of the weft yarn weft insertion process. No matter how many weft yarns are used for weaving, all weft yarns need to use the same weft insertion channel, and multiple weft yarns can only be used in the traction process. The main nozzles are used for weft insertion, and all the main nozzles must be aligned with the profiled reed channel, which limits the number of weft insertions of the air-jet loom, which in turn limits the variety of weft-colored fabrics that the high-speed and efficient air-jet loom can use adaptability

At present, during the weft insertion process of the air-jet loom, it can insert weft yarns of up to 8 colors. The domestic and imported looms on the market can realize this function, but when the number of color wefts exceeds 8 color wefts, only the sword Pole looms are used for weaving, limiting the use of air-jet looms
