Problems solved by technology

[0003] The purpose of the present invention is to provide a process for minimizing the warp and weft elongation deviation of fabrics for airbags, which can overcome the problem of excessive warp and weft elongation deviation in the existing fabric weaving and processing technology. After finishing, the warp and weft shrinkage of the fabric is small and basically balanced, and it remains stable at room temperature without tension

Abstract

The invention discloses a warp-weft directional elongation deviation minimization process of a fabric for an airbag. The process comprises the following steps of: 1) washing and refining: washing and refining the fabric, wherein the refining reagent is NaOH aqueous solution containing a refining agent, a dispersant and a penetrating agent; 2) extrusion and water filtration: removing moisture from the rinsed fabric through an extrusion roller; 3) thermal finishing: performing thermal finishing on the fabric in a drying oven, and regulating the over feeding value by 0 to 5 percent according to the breadth of the fabric; and 4) cooling to obtain a finished product. According to the method for finishing the fabric for the airbag, the warp-weft directional elongation deviation is reduced within 5 percent, and the shrinkage consistency is ensured; and the utilization of the fabric is maximized during cutting, the waste is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to a finishing process of textile fabrics, in particular to a process for minimizing the deviation of warp and weft elongation of fabrics for airbags, aiming to reduce the warp and weft properties of fabrics, especially the deviation of elongation to 100% Within five, so that the airbag fabric can be placed randomly in the warp and weft directions during cutting, so as to maximize the use of the fabric. Background technique [0002] At present, the fabrics for airbags mainly adopt plain weaving technology. Plain weaving refers to the weaving method in which one warp thread is pressed against one weft thread and one weft thread is pressed against one warp thread. The original silk organization of the fabric is that the warp and weft cross at 90 degrees. Due to the difference in warp and weft tension of the loom during the weaving process, and this difference is unavoidable, the fabric precursors stretch to different degrees in the...
