Technology for producing high-standard fluorescent safe protective polyester and cotton interwoven fabric by using domestic fluorescent disperse dye

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.

Production method for singeing and mercerizing single yarn

The invention provides a production method of singeing and mercerizing a single yarn. In the method, appropriate cotton is selected, a singeing and mercerizing process is studied and confirmed, and a process appropriate for the mercerizing of the single yarn is obtained to ensure that the breaking strength loss of the single yarn after the mercerizing is little; the single yarn is not easy to break in the weaving process; and the pattern of the fabric weaved with the single yarn has novelty and peculiarity. The production method for singeing and mercerizing a single yarn is characterized by sequentially comprises the processes of combing the single yarn, singeing, reeling, mercerizing, dyeing, wringing, drying, and rewinding; the singeing process specifically comprises the step of singeing the single yarn by a singeing machine to burn up the hairiness on the surface of the single yarn at a singeing temperature of 800 DEG C-1050 DEG C; and the mercerizing process specifically comprises the step of mercerizing the processed single yarn by a mercerizing machine, wherein the processing temperature is 18 DEG C-22 DEG C, the processing time is 6 minutes 30 seconds to 6 minutes 50 seconds, the processing tension of the single yarn maintains -1.0%-0% of stretching, and the alkali concentration in the processing fluid is 26 baume degrees to 30 baume degrees.

Preparation technology of alkali-resisting PTFE (polytetrafluoroethylene) and PPS (polyphenylene sulfide) fiber blended needled felt

The invention belongs to the technical field of industrial dedusting application and particularly discloses a preparation technology of alkali-resisting PTFE (polytetrafluoroethylene) and PPS (polyphenylene sulfide) fiber blended needled felt. The preparation technology comprises following steps: step 1, fiber opening; step 2, fiber carding; step 3, lapping; step 4, needling compaction; step 5, postprocessing: (1), calendering; (2), singeing; (3), impregnation with an emulsion; (4), high-temperature setting; (5), film covering. The preparation technology of the alkali-resisting PTFE and PPS fiber blended needled felt has beneficial effects as follows: 1, a PTFE fiber+PPS fiber needled felt filter material is a filter material with a stereoscopic fiber structure, and the filter material isformed by covering two sides of base cloth with stereoscopically staggered PTFE fibers and PPS fibers respectively, compacting and fixing the base cloth and then needling the base cloth by a needlingmachine; 2, the needled felt filter material has a small bore diameter, low filtration resistance, good breathability and high dust capturing efficiency. The filtration efficiency can reach 99.99% orabove.

Continuous processing technology for non-shrink treatment of chlorine-free wool top and wool product

The invention relates to a continuous processing technology for non-shrink treatment of chlorine-free wool tops and wool products. The continuous processing technology comprises the following steps: non-shrink treatment, washing, inactivation of protease, softening, dehydration, and drying. On the basis of the characteristic that wool fiber is protein fiber, the processing technology employs a high-efficiency integrated catalysis system composed of protease, a water-soluble aliphatic tri-substituted organic phosphine structured activator, a metal salt and a nonionic surfactant to efficiently and partially remove scales on the surface of the wool fiber so as to realize modification of the scales; thus, the felting performance of wool products is improved, dimensional stability of wool products is enhanced, and the requirement for machine washability is met. The continuous processing technology provided by the invention can replace chlorination anti-shrinkage methods in the prior art, avoids environmental pollution caused by the chlorination methods and is a clean treatment process according with environmental requirements. The continuous processing technology is small in usage amounts of reagents, low in cost, simple in process, low requirements on equipment and capable of realizing continuous operation and industrial production.
