Description
Technical Field
The invention belongs to the technical field related to textile fabric processing, and particularly relates to a preparation method of a soaping agent for polyester-polyurethane fastness.
Background
The reactive dye dyeing is the main dye variety for dyeing the cellulose fiber and blended fabric at present, and the dosage of the reactive dye is increased year by year. Reactive dyes are various in types, chemical structures and reaction efficiency, but the reactive dyes cannot completely react with fibers. In addition, when the fixed fiber is dyed, the dye can be hydrolyzed, the diffusion and adsorption properties of the unfixed dye and the hydrolyzed dye are very similar to those of the original active dye, the unfixed dye and the hydrolyzed dye are easy to adsorb on the surface of the fiber and diffuse into the fiber, and can be combined with the fiber under certain conditions, so that the impurities can be removed only by multiple washing and soaping processes, so that the color brightness, the color fastness and the cleanliness of the fabric are improved, and the process of removing the impurities is called soaping.
However, the traditional soaping process is carried out at high temperature through a chemical detergent, the processing energy consumption is high, the water consumption is high, the dye or the hydrolytic dye which is not combined can be directly discharged into the printing and dyeing wastewater, the burden of wastewater treatment is increased by the excessive chemical detergent added in the soaping process, the energy conservation and emission reduction of dyeing and the ecological property of processing are directly influenced, and the environmental pollution is caused.
The main chemical composition of polyurethane fiber (commonly called spandex) is polyurethane, and it is a block copolymer composed of so-called soft segments and hard segments. The elastic fiber is a fiber with a 'segment' structure and good elasticity, wherein a hard segment is formed by the reaction of isocyanate and a diamine compound, a soft segment is formed by a long-chain dihydroxy compound (polyether diol or polyester diol), the fiber is softer, the melting point is generally below 50 ℃, the glass transition temperature is generally-50 to-70 ℃ (polyether type) and 25 to 45 ℃ (polyester type), and different components are introduced into molecular chains of different commodities so as to improve various properties of the fiber. The elastic fabric is obtained by blending with fibers such as terylene, cotton and the like.
In the prior art, the polyurethane fiber dyeing is only suitable for disperse, neutral and other dyes, the dyes mainly enter a soft chain segment area with an amorphous structure, although the dyeing temperature is low, the dye uptake is not high, the dyes are easy to desorb, and the color fastness is poor.
