Non-woven bags are inexpensive and good-quality, widely used, environmentally friendly and practical, and have prominent advertising positions. Non-woven bags are suitable for various business activities and exhibitions. So do you know what other classifications of general non-woven fabrics have in the production process?
The classification of non-woven bags according to different production processes is as follows:
1. Heat-sealing non-woven bag: refers to adding fibrous or powdery hot-melt adhesive reinforcement material to the fiber web, and the fiber web is heated, melted and cooled to reinforce into a cloth.
2. Spunlace non-woven bag: It sprays high-pressure fine water stream onto one or more layers of fiber web to make the fibers entangled with each other, so that the fiber web can be reinforced and have a certain strength.
3. Pulp air-laid non-woven fabric bags: also known as dust-free paper and dry paper-making non-woven fabrics.
4. Wet-laid non-woven bags: open the fiber raw materials in the water medium into single fibers to make a fiber suspension slurry, and the fibers are formed into a net in a wet state and then reinforced into a cloth.
5. Spunbond non-woven bags: After the polymer has been extruded and stretched to form continuous filaments, it is then subjected to self-bonding, thermal bonding, chemical bonding or mechanical reinforcement to make the web It becomes a non-woven fabric.
6. Melt-blown non-woven bag: its process: polymer feeding---melt extrusion---fiber formation---fiber cooling---netting---reinforcement into cloth.
7. Stitched non-woven bag: It is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to reinforce the fiber web, yarn layer, non-woven material or their combination. To make a non-woven fabric.
8. Needle-punched non-woven fabric bag: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric uses the puncture effect of a needle to reinforce the fluffy web into a cloth.
The production process of non-woven bags is mainly based on the above categories. It is very important for us to use non-woven bags in the correct way.
