How To Overcome The Disadvantages Of Natural Leather

What is a two-component spunbonded spunlaced nonwoven leather fabric?

Spunbonded spunlaced nonwovens are made of filament spunbonded and Spunlaced together. A new type of nonwovens made of two kinds of polymer PET/PA6, which is produced by conjugate spinning, airflow drafting, net spreading, spunlace, drying, calendering and winding, is prepared.

The main technology is the spunlaced stripping technology in two-component spunbonded nonwovens. The hollow orange petal microfiber filament is finished through the back spunlace.

And consolidated, forming two component superfine fiber spunbonded spunlaced nonwovens.

"Spunlaced with Microfiber

To produce high-grade artificial leather for raw materials, because of its formation of a more compact and disordered three-dimensional structure than ordinary synthetic fibers, the leather made can achieve a false degree of authenticity, and greatly improve peel strength and fastness, overcome the shortcomings of natural leather which is easy to mold, smell, embrittlement and strength, and achieve the excellent performance of natural leather.

Huang Youpei said.

Therefore, microfiber spunlaced nonwovens can meet the needs of shoe leather, luggage leather, sofa leather, automotive interior leather and so on, providing good foundation and development space for garment leather, and upgrading products in the application field of non-woven fabrics.

China is the world's largest producer and consumer of synthetic leather and synthetic leather. It has developed to 80% of the world's market share and ranks first in the world. But at present, the production capacity of our ultra fiber leather is about 120 million square meters, accounting for only 3% of the total leather. Compared with the proportion of 85%~ 90% in Japan's Microfiber artificial leather, our country is far apart from it.

It is understood that at present, the manufacturing technology of "super fiber leather" is mature in China. The super fiber leather enterprises represented by Shanghai Huafeng, Shandong Tong Da, Yantai Wanhua, Wuxi double elephant and Zhejiang Hexin, all adopt the two step production process of short fiber + loose, carding + acupuncture, to produce ultra-fine leather.

The enterprises represented by Ji'an Sanjiang and Langfang spinning new yuan adopt the one-step two-component microfiber spunbonded and spunlaced process equipment technology developed by Dalian Hua Lun Chemical Fiber Engineering Co., Ltd. to produce super fiber leather base cloth. Compared with other domestic enterprises, the process flow is short, investment is low, energy consumption is low, pollution free, and the product is strong.

At the same time, it also has a considerable advantage in the price of equipment.

"Microfiber spunbonded spunlaced nonwovens production line has only 4 production lines in Jiangxi, Ji'an, Sanjiang, Langfang, China textile, Xinjiang, Tianjin, and Henan, and the annual production capacity is not more than 7000 tons.

Only Germany, Germany and Korea BAIKSAN have entered commercial production, and the scale and quantity of production can not meet the market demand.
