Problems solved by technology

[0019] The purpose of the present invention is to provide a penetrating aid for improving pigment dispersion and dyeing color fastness, which is combined with a solvent and a dispersant to get rid of the adverse effects of traditional paint binders and thickeners on the product feel, so that the pigment is suspended The body maintains a fine and dispersed state during the whole dyeing process, does not coagulate, does not deposit, and has sufficient penetrating ability to overcome the "white core" problem of synthetic leather dyeing and overcome the color flower of ultrafine polyamide / polyurethane suspension dyeing problems, and overcome the problems of poor color fastness after dyeing and poor color homogeneity of polyamide and polyurethane two-component

Abstract

The invention discloses a penetrating addition agent which comprises the following compositions in weight portion: 0.00018 to 0.0006 portion of laurocapam, 0.5 to 25 portions of myristyl lycine, 0.1 to 12 portions of dipropylene glycol methyl ether, 0.01 to 5 portions of N- methyl pyrrolidone, 0.05 to 2.5 portions of tri n butyl phosphate, 5 to 60 portions of diethylene glycol or butyl ether, 1 to 20 portions of phenylcarbinol and 1 to 3 portions of lignin sulfonic acid ammonium salt. The invention also discloses an application of the penetrating addition agent to the dyeing process and to the retting hemp process. The penetrating addition agent in the dyeing process ensures that the color yield and homochromatic properties of the double-component fiber are good, the leveling property is good and the 'white core' phenomenon is avoided.

Description

technical field [0001] The present invention relates to the field of textiles, in particular to a penetration aid, which has the characteristics of improving pigment dispersion and color fastness, so it can be used in the dyeing process, and the penetration aid can also be used in the hemp degumming process application. Background technique [0002] The manufacture of synthetic leather compounded by ultrafine polyamide and polyurethane is emerging in China. Due to factors such as color fastness, the grade and added value of the product are low, which seriously affects the quality of the product, and its price is only one-tenth of similar products abroad (such as Japan). If a breakthrough can be made in the aspect of color fastness, it will significantly improve the foreign trade growth of my country's synthetic leather industry. [0003] Although pigments have been used for many years in paint, pigment printing, paint, ink, oil paint, oil color, iron printing, rubber, plas...
