Abstract

The invention relates to a production process of a high color fastness polyester blended blanket. The production process comprises the following steps of spinning, performing warp knitting, cutting, repairing, sizing, setting, preshearing into coils, printing and dyeing, decating, performing water washing, stentering, inspecting, opening wool, gigging, ironing and shearing and cutting, wherein raw materials are polyester fibers, viscose and cationic modification fibers; a printing and dyeing process is to dip in a dye solution and immerse into color fastening liquid in sequence. According to the production process disclosed by the invention, a conventional dyeing process of the polyester blended blanket is improved; a dual temperature dyeing method of low temperature dyeing and high temperature dyeing in sequence with bi-reactive group active dye is adopted to improve the utilization rate of dye. The production process disclosed by the invention has the advantages that a product is high in color fastness, and production energy consumption and pollution discharge are effectively reduced, thereby reducing the production cost; the production process has a good market effect.

Description

technical field [0001] The invention relates to a fabric production process, in particular to a production process for a high color fastness polyester blended blanket with high product color fastness, low production energy consumption and low pollution. Background technique [0002] With the development of society, consumers have higher and higher requirements for consumption quality and diversification. Cotton fiber in the traditional sense can no longer meet the needs of such consumers. Therefore, blended fibers are favored by more and more consumers. Acceptance and love, as a high-end yarn-dyed fabric in textiles, because it involves more processes and functional finishing, it has higher requirements for color and yarn quality. [0003] The traditional dyeing of polyester yarns has a long production process, relatively high labor intensity, poor dyeing quality, more hairiness, inaccurate colors, large layer differences and poor strength, and low production efficiency, whi...
