Production method of warp knitting leather imitation cloth possessing high strength wear resistant property

Abstract

The invention relates to a production method of warp knitted leather base cloth with high-strength wear resistant. Step is as follows: 1) Fore treatment: adding 1.5-2g / L pure caustic soda to loom stare with the bath ratio of 1:15. After heating-up to 50deg.C-60deg.C, wash it twice and then make it clean with room temperature waiting for dye. 2) Dyeing: adding dyestuff and staining solution to loom stare after treated (room temperature). 3) Approved product: After dewatering and open width, the loom stare begin to pro-approved. Adding raising flexible agent, hygroscopic quick-drying dressing agent, then approve it on 190deg.C. Depth rising three times by 851 24 needle roll redouble raising machine, carding once by raising machine. Then finish approved, the temperature is higher then pro-approved, with the temperature of about 195deg.C-200deg.C,at the speed of 35-40m / min. Control the open width of end products at 150cm and thickness at 1-1.2mm. The method is characterized in that the products have high strength, good wear-resisting property, function and ring protection. Various performance indexes of the products are all higher than others.

Description

technical field [0001] The invention belongs to the field of fabric coating, in particular to a production method of a high-strength and wear-resistant warp-knitted imitation leather base cloth. Background technique [0002] With my country's successful entry into the WTO, the pattern of world economic integration has basically taken shape, and my country's economy is melting into the ocean of the world economy at an unprecedented speed. As a traditional industry in our country, textiles are closely related to people's production and life. Especially in the past two decades, the warp knitting industry has risen rapidly. Its products cover industry and agriculture, construction, decoration, culture and sports, medical care, machinery Manufacturing and other fields of society. Warp knitted imitation leather base fabric has been widely used because of its low cost, good simulation effect, and good design randomness. In the past, the warp knitting coating used the loose struct...

AI Technical Summary

Problems solved by technology

In the past, the warp knitting coating used the loose structure of two combs, which often had uneven fluff, poor imitation leather coating effect, no wear resistance, and poor strength. There are still many shortcomings, such as poor wear resistance and poor air permeability. , the color fastness is poor, the environmental protection index is not ideal enough, the appearance size is not stable enough, and the application field of the product is also quite limited.
