What Are The Production Processes Of Nonwoven Fabrics

The characteristics of nonwoven fabrics that are conducive to decomposition have a great impact on the environmental protection of daily waste. According to the name of the Non Woven Fabric, its manufacturing process is different. The following describes the production process of some non woven fabrics.

1. Spunlace Nonwoven Fabric: The high - pressure micro - water jet is sprayed into one or more layers of fiber webs to entangle the fibers together. The fiber web is strengthened and has a certain strength.
2. Heat - sealing non woven fabrics: refers to adding fibrous or powdery hot - melt adhesive reinforcement materials to the fiber web, and then heating, melting and cooling to reinforce the fiber web into cloth.

3. Pulp air - laid nonwoven fabric: also known as dust - free paper and dry - laid nonwoven fabric. The utility model uses air - flow weaving technology to loosen the wood pulp fiberboard into a single fiber state. The fibers are then adhered to the mesh curtain by the air method, and the fiber web is consolidated into a cloth.

4. Wet - laid nonwoven fabrics: The fiber raw materials placed in the water medium are loosened into single fibers, and different fiber raw materials are mixed at the same time to make fiber suspension pulp. The suspension slurry is transported to the netting tissue, where the fibers net in a wet state and then consolidate into a cloth.
5. Spunbond non woven fabric: After the polymer is extruded and stretched to form continuous filaments, the filaments are spread into a mesh. The web is self - bonded, thermally bonded, chemically bonded or mechanically reinforced.
