Environment-friendly polyester fabric low-temperature dyeing promoting protective agent and preparation method thereof

Abstract

The invention discloses an environment-friendly polyester fabric low-temperature dyeing promoting protective agent and a preparation method thereof. The low-temperature dyeing promoting protective agent is prepared from the following components of, in parts by weight, 25-45 parts of maleic anhydride derivative, 15-30 parts of organic esters, 15-35 parts of nonionic surfactant, 10-15 parts of anionic surfactant, 5-10 parts of solvent, 1-3 parts of antibacterial agent and 35-45 parts of water, and the nonionic surfactant is prepared from isomeric alcohol polyoxyethylene ether EH-3, fatty alcoholpolyoxyethylene ether AEO-9 and isomeric alcohol TO-5. According to the environment-friendly polyester fabric low-temperature dyeing promoting protective agent, the dyeing accelerating effect under the low-temperature condition is good, the influence of temperature fluctuation on the disperse dyeing yield can be effectively reduced, and under the low-temperature condition, wool and spandex components in polyester / wool, polyester / spandex and other blended fabrics are effectively protected from being damaged; and the protective agent is low in foaming, the product is environment-friendly and non-toxic, and the protective agent meets the newest environment-friendly requirement.

Description

technical field [0001] The invention relates to the technical field of textile chemicals, in particular to an environment-friendly low-temperature dyeing accelerator and protectant for polyester fabrics and a preparation method thereof. Background technique [0002] The differences in the physical and chemical properties of polyester fibers and other fibers such as wool, spandex, and others require that each fiber be dyed with a different dyeing process. In order to ensure the high dyeing rate of polyester and reduce the damage of other components of blended fabrics, it is necessary to develop effective new auxiliaries or dyeing methods in the industry. [0003] In recent years, some low-temperature dyeing auxiliaries and dyeing technologies have appeared in the domestic market, which can make the low-temperature dyeing rate of polyester blended fabrics reach a higher level, but these auxiliaries still have the following problems: (1) under low temperature conditions, polyes...

Problems solved by technology

[0003] In recent years, some low-temperature dyeing auxiliaries and dyeing technologies have appeared in the domestic market, which can make the low-temperature dyeing rate of polyester blended fabrics reach a higher level, but these auxiliaries still have the following problems: (1) under low temperature conditions, polyester The fiber penetration and level dyeing properties are poor, and the effect of auxiliary agents is not ideal; (2) the low temperature coloring property is not bad, the utilization rate of dyestuff is low, and the color yield is low; (3) the ability of auxiliary agents to diffuse dyes in fibers is improved Not enough, a large amount of dyes are adsorbed on the surface of the fiber, resulting in poor color fastness of the fabric; (4) The damage protection of fibers such as wool or spandex is not enough; (5) High foaming is not conducive to product quality control during production and processing

[0004] CN105133395A discloses a dyeing auxiliary agent for wool and polyester blended yarn, including tea polyphenol, borax, polyoxyethylene ether, branched isomeric alcohol ether, glycerol monoacetate, ethylene glycol monobutyl ether, ethylene glycol Composed of amine di-o-hydroxyphenyl macroacetate, ammonium tristyrylphenol polyoxyethylene ether sulfonate and water, the dyeing auxiliaries are added together with the dye during the dyeing process, which can effectively improve the dyeing effect of wool and polyester blends during dyeing. Yarn color fastness, but its temperature requirements are relatively strict, requiring high temperatures of 130-135 ° C, high energy consumption, not suitable for industrial applications

[0005] CN102619101A discloses a short-process low-temperature dyeing auxiliaries and a preparation method thereof, which mainly consists of the following components: maleic acid acrylic acid copolymer, ethylenediamine di-o-hydroxyphenyl macroacetate, ethylenediaminetetramethylene Sodium phosphonate, hydantoin, alkyl polyglucoside, ethylene glycol phenyl ether, sodium glycine, tristyrylphenol polyoxyethylene ether sulfonate, secondary alcohol polyoxyethylene ether, benzyl benzoate, etc. The dyeing auxiliaries of this invention can be directly dyed at 120-125°C; but this invention does not improve the diffusion ability of dyes in fibers enough, and a large amount of dyes are adsorbed on the surface of fibers, resulting in poor color fastness of fabrics
