Production process for weaving all-cotton cutting motif fabric by air-jet loom

Abstract

The present invention discloses a production process for weaving all-cotton cutting motif fabric by an air-jet loom. The production process comprises the following steps of winding process, warping process, sizing process, drawing-in process, weft preparation, and weaving process. The cutting motif fabric is usually weaved by a rapier loom and is not suitably weaved by a high-speed air-jet loom. According to production process, the cutting motif fabric is weaved by the air-jet loom, product quality and production efficiency are ensured, and enterprises gain considerable benefits. Ground warp threads are drawn in front zones of heald frames, and droppers are drawn in back zones, thereby facilitating reduction of tension force of the ground warp threads. Colored warp threads are drawn in the back zones of the heald frames, droppers are drawn in the front zones, and tension force of the colored warp threads is relatively small, thereby facilitating increase of the tension force of the colored warp threads and reduction of knees defects. When the former processes are performed for production, the winding and warping processes are performed at a low speed, air splicing is configured to the winding process so as to reduce yarn hairiness, coating is important in the sizing process, the weaving process is assisted by early opening, large tension force and late weft insertion and the like, and the problem of weft stop is solved.

Description

technical field [0001] The invention belongs to the field of fabric production, and in particular relates to a production process for weaving all-cotton flower-cut fabrics on an air-jet loom. Background technique [0002] Scissor fabric is to partially weave part of the warp or weft yarns in the fabric into the fabric, and then cut off the excess warp yarns or weft yarns. Cut flower fabrics can reflect popular fashion, have a fast update cycle, and have strong market adaptability. They are used in more casual occasions, such as women's casual wear and shirts, so they can better meet the fashion needs of the public. Cut flower fabrics are mostly woven by rapier looms because the opening of the flower warp is not easy to see. In order to develop high-grade cut flowers fabrics, we have developed an air-jet loom to produce cotton cut flowers fabrics. [0003] Cut flower fabric has two warp systems, ground warp and flower warp, and the interweaving times are very different, so ...

AI Technical Summary

Problems solved by technology

[0003] Scissor fabric has two warp systems, ground warp and flower warp, and the interweaving times are very different, so biaxial weaving is required. Among them, the flower warp system uses a self-made friction let-off system to let off the warp, and the opening is not easy to be clear.
