In recent years, the production capacity of spunbonded nonwovens in my country has expanded significantly, but there are still many gaps compared with foreign countries. Under the current situation, there is still a lot of gap between my country's spunbond equipment and production technology compared with foreign countries. This article briefly introduces the development background of Spunbond non woven for S cut.
After these years of development, my country's spunbonded nonwovens equipment has developed from relying on imports to equipment exports, from one type to multiple types, and has formed the largest equipment manufacturing volume, the hottest sales volume, and the most exported equipment in the world. The most prosperous situation. However, from the technical level of equipment, the manufacture of spunbond equipment in my country is still limited to imitation, and there are few original equipment with independent intellectual property rights. Compared with foreign equipment, there is still a big gap in quality, and high-quality equipment cannot be produced. The product.
The competition of domestic equipment only wins at low prices. This kind of competition that relies on price competition and ignores technology results in the high-end equipment market being handed over to developed countries and regions such as Europe, the United States, and Japan, which slows down the development of my country's spunbond equipment. Technological progress and improvement also affected the development of Spunbond non woven for S cut.
At present, the raw materials used by domestic spunbond enterprises are limited to PP and PET, the spinning method is only single-component, and the bonding methods are only hot rolling and needle punching. The raw materials of foreign spunbond products have been developed to OPP, PET, PA, PE, PU, PLA, etc. Basically, all melt-spun polymers can be used as raw materials for spunbonded nonwovens, and have been industrialized. The two-component composite product, the bonding method has been hot rolling, needle punching, spunlace and hot air, etc., a variety of raw materials and a variety of bonding technologies have greatly changed the performance of spunbond products to meet the market demand for different purposes .
Lack of high efficiency in production, there is still a big gap between the production efficiency of my country's equipment and the international advanced level.
At present, there are few special raw materials for the production of spunbonded nonwovens in China, and most of them still use general chemical fiber spinning raw materials, and the product performance is affected to a certain extent. The spunbond method has different requirements on the raw materials than the general spinning method, and has higher requirements on the fluidity of the raw materials and the uniformity of molecular weight distribution.
At present, judging from the current application status of spunbond nonwovens, in order to change from a spunbond power to a spunbond power and participate in international competition, it is necessary to further develop new areas for the application of spunbond nonwovens. The foreign Spunbond non woven for S cut has been widely used in many fields. Therefore, from the perspective of universality and extensiveness of application, there is still a wide range of markets in my country that have not been developed.
