Abstract

The invention relates to dyeing of fluorescent safe protective polyester and cotton interwoven fabrics, in particular to a technology for producing a high-standard fluorescent safe protective polyester and cotton interwoven fabric by using a domestic fluorescent disperse dye. The technology comprises the following steps of: (1) bleaching pretreatment: enhancing bleaching of a polyester and cotton interwoven fabric by adopting a jig dyeing machine, and removing residual hydrogen peroxide on the interwoven fabric by using a hydrogen peroxide removing enzyme to improve the dyeing uniformity of the fabric; (2) high-temperature and high-pressure dyeing: [1] performing heat preservation level dyeing for 4 times at the temperature of 60 DEG C, so that the fluorescent disperse dye is absorbed uniformly on the surface of the fabric as much as possible; [2] strictly controlling the dyeing rate and the pH value by adopting a method for controlling a dyeing temperature rise curve to satisfy the level dyeing conditions; and (3) reductive washing: performing reductive cleaning, oxygen rinsing and acid washing neutralization after dyeing, rewashing, drying, performing after finishing, tentering, sizing and inspecting the finished product, wherein a mixed solution of rongalite and caustic soda is adopted in the reductive cleaning. The domestic fluorescent disperse dye is produced by adopting high-temperature and high-pressure jig dyeing equipment, has obvious advantages, and is detected through quality standards of EN-471.

Description

technical field [0001] The invention relates to the dyeing of polyester-cotton interwoven fabrics for fluorescent safety protection, and is a production method of a dyeing technology that meets the EN-471 European standard by screening and applying domestic fluorescent disperse dyes for dyeing. Background technique [0002] Fluorescent dyed clothing fabrics, also known as high-visibility fabrics, are characterized by strong reflections on distant targets or targets in the dark under sunlight, moonlight or car lights, or targets that are very eye-catching and dazzling, and are particularly easy to see. It is found that it plays a good warning and safety prevention role, and improves the safety factor. [0003] In recent years, in the domestic and foreign markets, the application of special functional textiles to meet the special occupational environment has been refined and developed. For example, orders for fluorescent textiles with safety warning functions to be exported t...
