Description
Technical Field
The invention belongs to the field related to dyeing and finishing processes, and particularly relates to a preparation method of a green and tasteless dye-guiding agent for low-temperature dyeing of terylene.
Background
The polyester dyeing is usually carried out by adopting a high-temperature high-pressure method through disperse dyes under the conditions of 130 ℃ and pH value of 5-6. In recent years, with the continuous emergence of novel fibers, people pursue individuation, diversification and functionalization of clothes, so that the application of the multi-fiber composite fabric is wider. Some fibers which do not resist high temperature, such as wool, silk, acetate fiber, spandex and the like, are blended with the polyester fiber, so that the dyeing temperature is limited. Therefore, it has become a current trend to study how to dye under low temperature conditions.
The low-temperature dyeing process can reduce the cost in the aspects of machinery, energy, production cycle and the like, save the cost and reduce the energy consumption; on the other hand, the method can solve the problem of influence of high temperature on the fibers which can not resist high temperature, such as spandex, wool, real silk and the like, fully exert the advantages of various fibers, obtain high-quality dyed fabrics and expand the dyeing technology of the polyester composite fiber fabrics. Therefore, the method has very important practical significance for the research of the low-temperature dyeing method of the polyester fiber.
The key of low-temperature dyeing of the polyester fiber is to improve the plasticizing and bulking degrees, reduce the glass transition temperature and accelerate the diffusion speed of the disperse dye in the fiber. The current research and application method is to adopt a surfactant, an organic solvent, a carrier and certain physical and chemical methods, such as low-temperature plasma treatment, ultrasonic treatment, supercritical carbon dioxide fluid dyeing and the like, to achieve the effects of solubilization, dissolution assisting, plasticization and puffing, reduce the vitrification temperature of polyester fibers, improve the dyeing characteristics and realize normal-pressure low-temperature dyeing of the polyester.
The carrier method in the low-temperature dyeing method is the most environment-friendly, safe, efficient and easy to industrially produce. The dye-guiding agent, also called a carrier, is generally composed of some aromatic compounds with simple structures, such as: methyl salicylate (wintergreen oil), methylnaphthalene, chlorobenzene, biphenyl, o-phenylphenol and the like, and a small amount of emulsifier and cosolvent. The dye-guiding agents have heavy smell, high toxicity and poor biodegradability, and dyed fabrics have certain peculiar smell, thereby seriously influencing the production environment of factories. Still other dyeing agents, such as o-phenylphenol, are difficult to clean completely after dyeing, and the residual dyeing agents on the fabric can affect the light fastness of the fabric. Research on odorless (low-odor) nontoxic easily-removed environment-friendly dye-guiding agents is one of the development trends of polyester dyeing processes.
The commonly used environment-friendly dye-guiding agents comprise benzyl benzoate, N-alkyl phthalimide, N-alkyl pyrrolidone and the like, and the environment-friendly dye-guiding agents are nontoxic, tasteless (low-odor), biodegradable, easy to emulsify, good in emulsion stability, and free of reduction of the light fastness of dyed fabrics and damage to fibers. But the benzyl benzoate can also remain on the cloth surface after dyeing, so that the cloth surface has little smell; the preparation process of the N-alkyl phthalimide and the N-alkyl pyrrolidone is complex, and large-scale industrialization is difficult to realize.
Therefore, the environment-friendly polyester low-temperature dyeing dye-guiding agent which is simple in preparation process, can effectively reduce the dyeing temperature of polyester fabrics, and is non-toxic and odorless (low-odor) is in urgent need to appear.
