Abstract

The invention discloses an environment-friendly high-temperature leveling agent, which solves the problems of poor environmental protection, poor leveling property and dyeing penetration, and unsatisfactory leveling effect existing in the leveling agent of the prior art. It is mixed with different components: dodecyl propylene glycol benzoate polyoxyethylene ether 45~50%, sodium dodecyl diphenyl ether disulfonate 35~45%, ethylene glycol monophenyl ether 10~ 15%, the sum of the above components is 100%. The environment-friendly high-temperature leveling agent of the invention has the advantages of simple components, low cost, environmental protection, good leveling property and penetrating property. The invention also discloses a preparation method of an environment-friendly high-temperature leveling agent, first preparing polyoxyethylene dodecyl benzoate polyoxyethylene ether, and then combining Sodium diphenyl ether disulfonate and ethylene glycol monophenyl ether can be mixed according to the proportion. The preparation method of the invention has simple process steps and high process controllability.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to an environment-friendly high-temperature leveling agent and a preparation method thereof. Background technique [0002] Due to the large fiber surface area of ​​superfine fiber fabrics such as polyester imitation memory cloth and silk imitation cloth, the dye is quickly dyed; at the same time, due to the tight arrangement of the fibers, the pores between each single fiber are small, making it difficult for the dye to penetrate and further cause The uniformity of dyeing decreases; in addition, oils and waxes have a high affinity for superfine fibers and different shrinkage blended fabrics, and when they penetrate into the interior of high-density fabrics, it is more difficult to remove them. These impurities cannot be removed in pre-treatment. If it is effectively removed and brought into the dye bath, it will cause various dyeing defects. Existing high-temperature leveling age...
