Problems solved by technology

Cloth dyeing and finishing methods have a low dyeing sample rate, and color difference and creases are the main factors affecting the quality, so the loss is large, the cost is high, and the authenticity rate is low
[0006] Chinese Invention Patent Application Publication Specification CN101509206A discloses a method for dyeing polysulfone fiber cheese, but there are still many foams generated in the production process, resulting in waste of raw materials, stains may also be generated on the cloth, and bring inconvenience to production, and the color The fastness is also not good, and the dyed sulfonamide yarn feels bad, etc.

Abstract

The invention discloses a dyeing method for polysulfonamide yarns, comprising: 1, inverting yarns; 2, processing before dyeing: placing a cylinder yarn into a pretreatment water bath, then heating the water to a temperature between 50 DEG C and 60 DEG C at a speed of 2 DEG C to 3 DEG C per minute, washing the yarn for 5 to 10 minutes, then washing the yarn with clear water, and drying the yarn; Dissolvability of a detergent is 0.8 to 1.2 grams per litter, and the detergent is composed of the following compositions: 3-5 parts of castor oil ethylene oxide condensation products; 15-20 parts of laurinol polyoxyethylene ether; 15-20 parts of sodium dodecyl sulfate; 3-6 parts of dodecyl dimethyl betaine; 3-6 parts of coconut oil amide propyl group hydroxyl sulfobetaines, 3-6 parts of sodium polymethacrylate, 3-5 parts of polyvinylpyrrolidone; 2-4 parts of sodium citrate; 1-2 parts of sodium silicate; 2-4 parts of bentonite; and 50-80 parts of water; 3, dyeing; 4, processing after dyeing. The production process of the invention produces less foam, is easy to operate, has a high color fastness, and the dyed polysulfonamide yarns possess a soft hand feeling.

Description

technical field [0001] The invention relates to a method for dyeing yarns, in particular to a method for dyeing sulfonamide yarns. Background technique [0002] Polysulfone fiber, namely polysulfone amide fiber, is a heat-resistant and flame-retardant high-function fiber with good wearability developed and produced by my country. Polysulfone fibers have outstanding heat resistance, flame retardancy and high temperature dimensional stability, as well as good electrical insulation, radiation resistance and chemical stability. [0003] The fabrics and clothing processed by polysulfone fiber have permanent high temperature resistance and flame retardant protection function, and can always maintain the sufficient strength and wearability of the original foundation under harsh weather conditions such as high temperature and high humidity; Melt drops will occur, the fabric is dimensionally stable, and will not shrink strongly; it has comprehensive characteristics such as wear resi...
