Wide dyed flannelette processing method

Abstract

The invention discloses a wide dyed flannelette processing method. The wide dyed flannelette processing method comprises gray fabric weaving and dyeing and finishing, wherein gray fabric weaving comprises performing weaving on an air-jet loom and sequentially performing processes of warping, warp sizing, drawing-in, reeding, dropper penetrating, weft twist setting and weft insertion weaving to obtain a gray fabric, wherein the processes of weft twist setting and weft insertion weaving are implemented synchronously; during the process of weft twist setting, the yarn supply side of the weft insertion system of the air-jet loom is additionally provided with a yarn twist setting device; during weaving, weft yarns pass through the yarn twist setting device and then enter into sheds, and the yarn twist setting device spray sizing agent onto the head ends of the weft yarns. During wide fabric weaving, the weft yarns pass through the twist setting device and then enter into the sheds, and by spraying the sizing agent onto the head ends 25-20 mm long of the weft yarns, the head ends of the weft yarns can maintain stable twist and be less prone to untwisting, thereby avoiding affecting the hand feeling or other indexes of the woven fabric; after being sanded and dyed, the fabric can be uniform in color between the edge and the middle and high in sense of quality.

Description

technical field [0001] The invention belongs to the technical field of household textiles, and in particular relates to a processing method for wide-width dyed flannelette with uniform color in the edge. Background technique [0002] In recent years, the simple bedding style has become more and more popular, and the way of dyeing fabrics with embroidery or other styles has gradually become the mainstream. At present, the dyed bedding fabrics are mainly satin surface, which is suitable for spring and autumn, but there are relatively few warm-keeping velvet dyed fabrics suitable for winter, mainly because after the sanding process, the color difference between the sides of the wide-width dyed fabrics is very small. obvious. [0003] The reasons for the color difference in the edge are as follows: First, it is caused by the untwisting of the weft yarn in weaving. Since most of the wide-width fabrics are woven by high-speed air-jet looms, the principle of weft insertion is to u...

Problems solved by technology

Second, in terms of dyeing and finishing, local differences in sanding or napping equipment, such as different wear degrees of sanding or card clothing, will also aggravate the color difference in the edge

The third is the dyeing process, softening process, etc., will affect the color difference in the edge of the dyed flannelette

But the problem is that the installation of auxiliary nozzles will lead to too long air supply path. When the weft yarn is thick or there are several different weft yarns, weft shrinkage defects may appear due to insufficient air pressure, which will affect the appearance of the cloth surface, and the installation cost is high. Major equipment modification

The existing problem is that the degree of twisting at the head end of the weft yarn is difficult to control, and the yarn structure of the twisted part is different from that of commonly used ring-spun or compact-spun yarns, the fiber arrangement is different, and the twist and twist direction are inconsistent. The problem of chromatic aberration in the edge appears
