[0032] Raw material formula of the present invention carries out batching according to table 1, and unit is: kilogram

[0033] Table 1 raw material formula

[0034]

[0035] The preparation process of the present invention is: the selected pentaerythritol polyoxyethylene polyoxypropylene fatty acid ester, fatty diol terephthalate, biomass surfactant and maleic acid di-sec-octyl sodium sulfonate Mix evenly to obtain the oil-removing and leveling compound emulsifier of the present invention.

[0036] The beneficial effects that the degreasing and leveling compound emulsifier of the present invention has:

[0037] 1. It has good surface activity and has excellent emulsifying and dispersing effect on the oil agent on the fabric.

[0038] 2. It has good dye dispersibility, dye migration and dye uptake rate, has little effect on fabric shade, and can improve the success rate and reproducibility of dyeing at one time. Its migration, dye uptake rate and shade influence are shown ...

Abstract

The invention discloses an oil-removal uniform-dyed composite emulsifier and application thereof, aiming at solving the problems that an oil removing agent and a uniform dyeing agent are added in the existing oil removal and dyeing-bathing process, and improper oil removing agent influences the colored light of dyeing, uniformity of dyeing and high temperature dispersing performance of dyes. The composite emulsifier is prepared by compositing the following components in parts by weight: 180 to 220 parts of pentaerythritol polyoxyethylene polyoxypropylene aliphatic ester, 40 to 60 parts of 1, 4-fat glycol terephthalate, 80 to 100 parts of a biomass surfactant, and 20 to 60 parts of sodium diethylhexyl sulfosuccinate. According to the composite emulsifier, the surface tension of a solution can be obviously reduced, the emulsifying effect on brown oil on a fabric is good, the dye dispersing performance, uniformity, migration capacity and dyeing rate are outstanding, the influence on colored light of the fabric is slight, and the one-time dyeing success rate and the reproducibility can be improved.

Description

technical field [0001] The invention relates to the field of textile dyeing and finishing auxiliaries, in particular to an oil-removing and leveling compound emulsifier and its application. Background technique [0002] In the actual production process of printing and dyeing processing, due to various complex factors, it is inevitable to produce various defective fabrics. These defective fabrics are produced during the production process, such as uneven pre-setting temperature and large temperature difference, which may cause large dyeing color difference or two-sided color or two-sided color; the dyeing machine is shut down for some reason, and the cloth is blocked, which is easy to produce uneven dyeing ( Stained flowers, stains); the dispersion of the dye solution is unstable, and it is easy to cause the dyeing materials to gather or condense and adsorb on the surface of the fabric to cause dyeing spots, etc., but in many cases it is the problem of the original gray cloth...
