Introduction of Spunbond Nonwoven Process

The important reason for the active development of polypropylene non-woven fabrics is that it uses synthetic polymers as raw materials. This method dominates the spinning of chemical fibers. In the process of polymer spinning, filaments are continued, and after spinning, they are directly bonded to a mesh. It is combined into non-woven fabrics, and the production and weaving is very simple and fast.

Compared with the dry-laid non-woven fabric processing technology, polypropylene non-woven fabrics eliminate a series of cumbersome core processes such as fiber curling, cutting, packaging, conveying, assimilation, carding, etc. The result is that the cost of spunbond products is reduced, the quality is unchanged, and the market competitiveness is strong, and it can enter the market scale of textiles, paper and films in various applications of disposable and durability.

Secondly, since spunbond non-woven fabrics use polypropylene as an important raw material in large quantities, it has many advantages in terms of price, processing process, production cost, etc., which also greatly enhances the continuous development of spunbond non-woven fabrics industry. . In addition, the mechanical properties of spunbond non-woven products are excellent, and their tensile strength, elongation at break, tear strength and other indicators are better than those of dry, wet and meltblown non-woven fabrics, especially in recent years. The active development of the bonding method in the production line scale, technology and equipment, and product market development has greatly expanded the operating scale of spunbond non-woven fabrics.

The biggest difference between the spunbond production process and chemical fiber spinning is the use of air drafting and direct web formation. Therefore, the drafting of the spunbond method has become a technical problem. In the past, mechanical drafting was used. Weaving, the fiber monofilament is thicker, and the laying is uneven. At present, the spunbond production equipment in all countries in the world has adopted the airflow drafting technology. Due to the different airflow drafting systems, there are three different types of spunbond production lines, namely tubular drafting, wide slit drafting, and narrow slit drafting. Extend and so on.

Wenzhou Xinyu Non-woven Fabric Co., LTD. said that the spunbond non-woven technology has always been to improve the ability to cross the production line and solve the uniformity of non-woven fabrics, algae decoration, rough hand feeling, etc. Problems, in order to improve the strength, excellent flexibility, uniformity, comfort, moisture absorption and other properties of spunbond non-woven fabrics.

Wenzhou Xinyu Non-woven Fabric Co., LTD.'s products, whether interim or permanent, comply fully with all appropriate producing regulations.
Compare the various types of that are available. At XINYU Non-woven, the range is constantly being updated with new models, technical details and competitive prices.
The non woven application CUSTOMIZING has significantly numerous benefits over other flame retardant non woven fabric systems, which makes it first choice for non-woven product.
