preparation example Construction

[0020] The preparation method of this sofa leather with high wear resistance and flame retardancy mainly comprises the following steps:

[0021] 1) Wet coagulation coating: After the base fabric is pretreated, sizing and scraping coating on the coating machine, the sizing amount is 100~300g / m 2 , wet weight, knife distance 1.4~1.8mm, and then pass through the coagulation tank for solidification and molding, the concentration of dimethylformamide (DMF) in the coagulation tank is 8-25%, the temperature of the coagulation bath is 20-35°C, and the coagulation time is 5-15min; then enter Washing in the washing tank, the temperature of the washing tank is 20~90°C, and the DMF concentration in the last tank is 0~1%; after washing, it is dried and shaped, the drying temperature is 100~170°C, the time is 2~8min, and finally it is cooled and coiled, that is It is a semi-finished wet-laid bass; specifically: base fabric--pretreatment (brushing, pre-impregnation, calendering)--sizing and ...

Abstract

A high-wearing and fire-retardancy sofa leather is made by 1) wet condensing coating, molding in condensing groove, washing in water groove, drying and shaping and finally cooling and winding to become semi product wet process Bayes; 2) back spread coating with the semi product going through drawoff roller extraction shaping, dressing and spread coating, drying and baking and becoming fire-retardancy Bayes after cooling and winding; 3)nonaqueous shifting surface making, namely, separate paper shifting overlay; 4) kneading after treatment with pre-soaking of semi product sofa, squeezing out partial liquid, kneading and drying and finally batching on checking and final product packing. Apart from the major features of anti-friction and anti-retardancy, it can keep fine physical and mechanical performance and cosmetic styles with good quality and durable service.

Description

technical field [0001] The invention belongs to the field of fabric coating, in particular to a preparation method of sofa leather with high wear resistance and flame retardancy. Background technique [0002] With the rapid development of social economy, people's living standards are improving day by day. As a representative product to improve people's living standards and quality, furniture has attracted more and more attention. Among them, the most direct and prominent feeling is the performance of furniture decoration materials. At present, there are roughly the following types of decorative materials for furniture on the market, one is pure textiles, the other is genuine leather, the third is artificial leather, synthetic leather, and the fourth is microfiber imitation leather. Wherein artificial leather and synthetic leather occupy a considerable proportion (about 60%), the main reason is that it combines the advantages of many decora...
