A kind of island super fiber leather processing technology

Abstract

The invention discloses a sea-island microfiber leather processing process which includes a step S1 of spinning sea-island microfiber, adopting a figured sea-island method to spin sea-island microfibers; a step S2 of preparing sea-island microfiber non-woven fabrics, causing the sea-island microfibers to undergo opening, carding, lapping, pre-needling and needling, to obtain the sea-island microfiber non-woven fabrics; a step S3 of performing ultrasonic softening treatment on the sea-island microfiber non-woven fabrics; a step S4 of impregnating and curing the sea-island microfiber non-woven fabrics, impregnating the sea-island microfiber non-woven fabrics in resin liquid, performing repeated squeezing, and performing ultrasonic processing through an ultrasound instrument and drying through a drying oven, to obtain a sea-island microfiber leather base; and a step S5 of performing decrement, softening, expanding drying forming, skin kneading and dyeing, to obtain finished sea-island microfiber leather. According to the sea-island microfiber leather processing process, process arrangement is reasonable, organic matter volatilization in the production process is less, the sea-island microfiber leather processing process is environmentally friendly and is easily impregnated, the coloring speed is appropriate, and the prepared sea-island microfiber leather is uniform in color and good in softness.

Description

technical field [0001] The invention relates to the technical field of synthetic leather preparation, in particular to a sea-island microfiber leather processing technology. Background technique [0002] With the deterioration of the living environment and the decrease of animal resources, it has become an industry trend to use synthetic materials to replace natural leather for the protection of existing animals. Leather is the best substitute for natural leather. Its main application fields are shoe materials, bags, car interiors, clothing fabrics, handbags, craft decorative fabrics, and military supplies. At present, the global market is actively developing environmentally friendly imitation leather. [0003] The textile leather making material that the market adopts now is mainly made up of two parts. One part is the base fabric used for leather, and the base fabric is generally made of woven, knitted, woven, non-woven fabrics and other materials; the other is the surfa...

Problems solved by technology

[0004] In the preparation process of the existing sea-island microfiber leather, organic solvents N, N-dimethylformamide, toluene, etc. are usually used to reduce the sea in the sea-island microfiber leather. These organic solvents are used during production and use. Volatile organic compounds will not only pollute the environment, but also cause harm to the body of workers and users. In addition, in the preparation process of sea-island microfiber leather, the impregnation process is difficult and the impregnation effect is poor, which affects the subsequent dyeing process of sea-island microfiber leather. , so that the sea island microfiber leather is unevenly colored, and the coloring speed is too fast or too slow
