Foreign trade non-woven bags are divided into the following types according to the production process:

1. Spunlace non-woven fabric: The spunlace process is to spray high-pressure micro-water jets onto one or more layers of fiber webs to entangle the fibers with each other, thereby strengthening and strengthening the web.

2. Heat-sealed non-woven fabric: The heat-bonded non-woven fabric refers to adding fibrous or powdery hot-melt adhesive reinforcement material to the fiber web, and the fiber web is then heated and melted to cool and strengthen the fabric.

3. Pulp airlaid nonwoven fabric: Airlaid nonwoven fabric can also be called dustless paper and dry papermaking nonwoven fabric. It uses air-laying technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-flow method to agglomerate the fibers on the screen curtain, and the fiber web is then consolidated into a cloth.

4. Wet method non-woven fabric: Wet method non-woven fabric is to open the fiber raw materials placed in the aqueous medium into single fibers, and at the same time, different fiber raw materials are mixed to make fiber suspension pulp, which is transported to the web forming mechanism. The fibers are formed into a web in a wet state and then consolidated into a cloth.

5. Spunbond nonwoven fabric: After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then self-bonded, thermally bonded, and chemically bonded. Adhesive or mechanical reinforcement methods make the web into a non-woven fabric.

6. Meltblown non-woven fabric: Process of meltblown non-woven fabric: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- forming into a network --- strengthening into a cloth.

7. Needle-punched non-woven fabrics: Needle-punched non-woven fabrics are a type of dry-laid non-woven fabrics. Needle-punched non-woven fabrics use the piercing action of needles to reinforce fluffy webs into fabrics. Introduction to the editor of Wanguan Hardware Machine Grid

8. Stitch-knitted non-woven fabric: Stitch-knitted non-woven fabric is a kind of dry-type non-woven fabric. The stitch-knitting method uses warp-knitted coil structure to make webs, yarn layers, and non-woven materials (such as plastic sheets, plastic sheets, etc.). Metal foil, etc.) or a combination thereof to make a non-woven fabric.

9. Hydrophilic non-woven fabric: It is mainly used in the production of medical and hygienic materials to obtain better feel and not scratch the skin. Like sanitary napkins and sanitary pads, the hydrophilic function of hydrophilic nonwovens is used.

The difference between foreign trade non-woven bags and dust-free cloth Non-woven cloth, also known as non-woven cloth, is a new generation of environmentally friendly materials. It has the characteristics of water repellency, breathability, flexibility, non-combustion resistance, non-toxic and non-irritant, and rich colors. If the non-woven fabric is naturally decomposed outdoors, its longest life is only 90 days, and it will decompose within 5 years when placed indoors. It is non-toxic, odorless, and free of any residual substances when burning, so it does not pollute the environment and is suitable for washing. It directly uses polymer chips, short fibers or filaments to form new fiber products with soft, breathable and flat structures through various web forming methods and consolidation techniques. It has environmental protection properties that plastic products do not have. It is naturally degraded much less than plastic bags. Therefore, non-woven bags made of non-woven fabrics are also recognized as the most economical and environmentally friendly shopping bags.
