The primary production process of non -woven fabric

The canvas bag manufacturer introduces you the primary production process of non -woven fabrics: non -woven fabrics, also known as non -weaving fabrics, are a fabric that does not require spinning woven fabrics. There are many varieties. Non -woven fabrics such as dissolving spray, acupuncture, spinning, sewing, etc. Different fiber raw materials and production processes can be made into diverse product varieties. The product is soft, thick, and various functions and shapes.

At present, non -woven fabrics have been developed rapidly, and they have become a new industrial industry branch. Many countries and regions have established non -woven fabric production enterprises. The top three companies in non -woven fabrics are Freudenberg, Germany, Dupont, and Finland's Alstron, Finland. (Ahlstrom) Company. North America, Europe, and China are the developed areas of non -woven fabrics, and these countries and regions have also established the non -woven industry association.

At present, fibers are generally used in non -woven fabrics include polyphrobali, polyphoric, adhesive, etc. These three fibers account for more than 90%, and about 63%of polyalism is the primary raw material for non -woven fabrics. The spinning method is one of the primary production methods of non -woven fabrics. The share of the shopping malls produced by non -woven fabrics produced is also very large. The continuous long and short fibers are arranged as a mesh structure during the spinning process. The mesh fabrics are processed into non -woven fabrics after the processing of chemistry and thermal methods. Woven non -woven fabrics have good safety and environmental protection functions, strong flexibility, good fabrics, good breathability, and are widely used in furniture, clothing, architecture and other industries. There is a wide range of room for development in today's society where green textiles and green environmental protection and energy -saving design are advocated.

The rate of polybine resin solution activity to a large extent determines the production process and product functions of spinning non -woven fabrics. Domestic primary selection of uniformly gathered non -woven fabrics, and its melting activity rate is about 35g/10min. To a certain extent, it restricts the development of production technology and restricts the improvement of the quality of the product. Therefore, the rate of progress of polycopyllel dilute solution has the primary meaning, and has certain shopping mall value
