PE (polyethylene) non-woven fabric is a new type of non-woven fabric developed on the basis of PP/PE two-component non-woven fabric with core structure. It has the characteristics of non-toxic, skin-friendly, good thermal adhesion, and soft hand feeling. Especially suitable for the medical and health field, it is an excellent material for products such as surgical gowns, protective clothing, sanitary napkins, and diapers. At the same time, it can also be compounded with other materials and used in automotive interiors, waterproof materials and other fields. As early as 2002, Shanghai Synthetic Fiber Research Institute established the "PP/PE two-component composite spunbond nonwoven fabric" research group to develop PP/PE two-component (PE for sheath and PP for core) composite spinning Adhesive non-woven fabric. In 2003, the subject passed the appraisal of the expert group. In recent years, domestic companies producing skin-core two-component non-woven fabrics include Shaoxing Yaolong Spunbond Technology Co., Ltd. (introduced equipment from Nordson Corporation), Zhejiang Naite Filter Technology Co., Ltd., Wenzhou Changlong Technology Co., Ltd., and Hubei Hengtian K. Wah Nonwovens Co., Ltd. (introduced the SSMMMS die production line of Reifenhäuser, Germany), etc. The combined production capacity of these companies is about 30,000 tons/year, and their main customers are international buyers.

PE (polyethylene) low gram weight (12 grams) non-woven fabrics solves the problem of PP spunbond non-woven fabrics that need to add soft masterbatch or adjust the process to increase softness. Once it came out, it attracted the attention of the market, especially diaper manufacturers. However, PE non-woven fabrics appeared in an embarrassing situation of applauding. The market share is small. The application area is limited. Chen Hefu, general manager of Zhejiang Naite Filtration Technology Co., Ltd., pointed out the main reasons: First, in recent years, with the rapid growth of sanitary materials, a batch of 3S spunbonded non-woven equipment has been put into production one after another. They have improved the process and added softness. Methods such as masterbatch have greatly increased the softness and smoothness of PP non-woven fabrics, and the cost is lower than PE, which has robbed most of the market; second, most of the medical and health brand agents have the problem of defaulting payment, which affects The enthusiasm of enterprises to take orders; third, the high cost of PE non-woven products, narrow application areas, due to this limitation, the market recognition is greatly lagging behind; fourth, there are certain difficulties in PE technology, and the enthusiasm of enterprise development investment is not high.

There is a process of market recognition for a new product, such as two-component, including multi-component non-woven fabrics. After decades of development, it is rare that large-scale industrialization has not been formed. On the one hand, it shows that the domestic research and development capabilities in the field of spunbond non-woven fabrics are relatively weak; on the other hand, there are still many topics to be researched and developed for the expansion of a new product application field.

At present, some new technologies, new products, and new processes continue to break people's fixed thinking mode. The emergence of new materials and new fields, and the fierce market competition has forced many minded companies to constantly try to do new things. For many things we thought of as routine in the past, changing a perspective or thinking may produce unexpected results. Projects that have been developed abroad, such as two-component melt-blown equipment, variable-width melt-blown production lines, high-hole density spinnerets, etc., we do not currently have, and this also allows domestic manufacturers to see the gap. Some companies have raised funds to develop new products by listing on the New Third Board, and some companies are developing some market needs, but they are still blank. Like nano-filter materials, heat preservation, moisture-absorbing materials, high-grade wiping materials, etc., use new fibers, new processes, and new technologies to realize its multi-purpose; environmental protection (PLA materials), high temperature resistance (polyphenylene sulfide materials), and waterproof (PTFE materials) ) And other non-woven fabrics have been successfully developed, that is, using spunbond, meltblown, electrostatic spinning and other methods to create new uses and market opportunities through two-component or new functional fibers, making China's spunbonded nonwovens The field of cloth application is constantly expanding. With the rise of national entrepreneurship and mass innovation, it is reasonable to believe that my country's spunbonded nonwovens industry will usher in a wave of faster development opportunities.
