Simple new processing method for fiber

Abstract

The invention discloses a simple new processing method for fiber. The method comprises the following steps that a dispersing agent and water are added in pretreated sodium hydroxide, the mixture is stirred to be uniform, then polyurethane emulsion is added for blending, standing is performed after stirring and dispersing are performed, vacuum bubble discharging is preformed, and premix is obtained; the premix is measured through a metering pump and then enters a coagulating bath through a filter and a spinning jet for spinning, desulfuration, washing, oiling and drying are performed, and stretch-proof spandex fiber for heavy crepe de chine is obtained. The pretreated sodium hydroxide is prepared through the following processes that sodium hydroxide and a sodium hydroxide solution are stirred, N,N-dimethyl(cetyl)amine is added, stirring continues to be performed, centrifugation and washing are performed, hydrochloric acid is added, stirring, filtering and drying are performed, and the pretreated sodium hydroxide is obtained. Accordingly, the method is simple, the softness of the surface of the spandex fiber is extremely high, the mechanical property is good, breakage is not likely to occur, and the method is suitable for high-temperature printing and dyeing and can be applied to various crepe fabrics.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a new simple fiber processing method. Background technique [0002] Spandex is the abbreviation of polyurethane fiber. It is an elastic fiber and is widely used to make heavy crepe fabrics. Its silk surface is dense, fine and glossy. The pursuit of sex is also getting higher and higher. But at present, the thermal stability and mechanical properties of spandex fiber can not meet the demand and need to be solved urgently. Contents of the invention [0003] Based on the technical problems in the background technology, the present invention proposes a new simple fiber processing method, which is simple, low in cost, and environmentally friendly. The obtained spandex fiber has the characteristics of high heat resistance, high elasticity, and high temperature rinsing resistance, and the surface is soft. It has high strength, good mechanical properties, and is not easy to break. I...
