The production principle of spunbonded non-woven fabric!

The production principle of spunbonded non-woven fabrics mainly involves the process of converting polymer materials into fibers, and then bonding these fibers together to form non-woven fabrics. The specific process is as follows:

Preparation of raw materials. First, prepare polymer materials such as polypropylene (PP) particles, which is a polymer synthetic material obtained through petrochemical processing.

Melt extrusion. The polymer material is heated to a molten state and then extruded through an extruder.

Spin. In spinning, liquid polymers pass through high-speed spinning holes to form streams of fibers, which are stretched and twisted to form continuous filaments.

Lay a net. The filaments are laid into a network structure, a process that can involve chemical, mechanical or thermal methods.

Glue. The fiber mesh is bonded together by self-bonding, thermal bonding, chemical bonding or mechanical reinforcement to form non-woven fabric.

Post-processing. Finally, the non-woven fabric post-treatment, such as drying and winding, to complete the production process.

The production process of spunbonded nonwovens is not only simple and fast, but also can reduce costs and improve market competitiveness. Because the production process eliminates many of the complex steps of traditional textiles, such as fiber crimping, cutting, packaging, etc., it can achieve large-scale production and low cost

Qingdao Furuixiang Plastic Technology Co., Ltd. now has four advanced non-woven production lines, can produce 8-250 grams/square meter, width within 3.2 meters of various colors, sizes, functions (such as UV, anti-aging, antibacterial, flame retardant, hydrophobic, water repellent, super soft) SMS, SS, S polypropylene spunbonded non-woven fabrics. Qingdao Furuixiang Plastic Technology Co., LTD. 's non-woven fabrics are well received in the international market, and have passed a number of quality certifications such as SGS, ITTC, IAF, OEKO-TEX, CNAS, etc.
