Problems solved by technology

[0003] The defect of the prior art is that: the connecting line is a solid line, and the cutting edge of the fabric is easy to cause defects and loss. Usually, the drawing process is used, and the cutting is trimmed until the edge of the piece is straight.
The splitting process is cumbersome, and the garment processing efficiency and fabric utilization rate are low; the interlayer cavity at the connection point of double-faced wool is small, and the thermal insulation effect is not good

Abstract

The invention discloses an improved double-faced woolen production process, which includes the steps of spinning, weaving and finishing. The finishing includes washing, shrinking, drying for the first time, dissolving the connecting thread with hot water, and finishing for the second time. The drying step; the connecting thread of the double-layer weave of the double-faced cloth is polyvinyl acetal fiber yarn, and the fiber composition of the double-layer weave contains wool fibers; the process temperature of the washing and shrinking steps is lower than that of the above-mentioned polyvinyl alcohol The initial melting temperature of the acetal fiber yarn; when the above-mentioned connecting thread dissolves, a force that causes wool felt to shrink is applied to the double-faced wool. This production process arranges the double-faced wool into a double-layer structure without connecting lines. During the sewing process of the double-faced wool, the edge of the cut piece can be opened directly with sewing needles, completely avoiding defects and losses during the edge cutting operation, and improving the quality of the fabric. Sewing efficiency and fabric utilization.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an improved double-face woolen production process. Background technique [0002] The upper and lower layers of the double-faced woolen fabric are independent warp and weft structures. During the weaving process, the upper fabric and the lower fabric are interwoven and connected by connecting lines, or bonded with environmentally friendly modified fabric adhesives. In order to meet the needs of reverse stitching, hemming stitching or edge sealing, the upper fabric and the lower fabric are peeled off, and the fabric needs to be split with a double-sided wool splitting machine, or mechanical peeling and manual A combination of exposing and stripping. [0003] The defect of the prior art is that: the connecting line is a solid line, and the cutting edge of the fabric is easy to cause defects and loss. Usually, a return-drawing process is used to trim until the edge of the cut piece...
