Description

Superfiber impregnated color paste and preparation method thereof

technical field

The invention relates to the technical field of superfiber coloring, more particularly to a superfiber impregnated color paste and a preparation method thereof.

Background technique

The industrial production of artificial leather has a history of several decades. With the continuous application of various new materials, its products are also constantly updated. Microfiber synthetic leather (microfiber leather for short), as a member of artificial leather, is developed on the basis of fully analyzing natural leather. Because the production process of the microfiber leather is different from ordinary synthetic leather, there is no peculiar smell in the production process, and the microfiber leather has excellent wear resistance, cold resistance, breathability, and aging resistance, making the microfiber leather almost a perfect substitute High-grade genuine leather material. In addition, as a good substitute for real leather, the microfiber leather is regarded as a sunrise product of synthetic leather. It has been widely used in high-end leather consumer industries such as furniture, clothing, ball making, shoemaking, and automotive interiors. The blank market left by the withdrawal of natural leather.

Because the microfiber leather base cloth is usually white, it is necessary to color the microfiber leather base cloth before the imitation leather is finished on the microfiber leather to achieve a super-simulation effect. At present, the microfiber coloring treatment technology can be divided into impregnated section pigment coloring and greige dyeing, but because the impregnated section pigment coloring technology currently has the problems that the pigment is not resistant to toluene and the coloring degree is not high, so the requirement for color degree is relatively high. High-quality products usually use dyeing technology at present.

For microfiber leather, due to the extremely fine diameter of the superfine fiber in the microfiber leather (usually the fineness of the superfine fiber is only 0.0001-0.001 denier), the specific surface area is large, so that the microfiber leather can be used in the dyeing process. It has the advantages of fast dyeing speed and good migration. However, this dye dyeing technique also has some problems, such as poor level dyeing, poor deep dyeing and low color fastness (such as soaping, rubbing, perspiration, light fastness) and other defects. In addition, since the polyurethane molecule in the microfiber leather does not contain ionic groups, it is a hydrophobic substance and is not easy to swell in water, so the superfiber leather has poor ability to absorb dyes during dyeing. Furthermore, because the force between the molecular chains of the amorphous region of the polyurethane molecule is weak, the dyes adsorbed in the superfiber leather are also easy to migrate out, generally not easy to dye deep, and the color fastness is not good enough. In addition, the process of dyeing microfiber leather is relatively complicated, and there are problems of high energy consumption and pollution, which does not conform to the national sustainable development policy.
