The important material of the non-woven bag is a non-woven fabric. Taizhou environmental protection bag is a kind of non-woven fabric. The advantages of non-woven bag: non-woven bag is cheap and good, environmentally friendly and practical, widely used, with prominent advertising position, suitable for all kinds of business activities and exhibitions and fairs. Miracle unit ideal advertising promotional gift giveaway. Non-woven bag classification non-woven bag can be divided into: according to the difference of production process:
1. Spunlace non-woven bag: It is a high-pressure fine water flow radiated to one or more layers of fiber web to make the fibers entangled with each other, so that the fiber web can be reinforced and has a certain strength.
2. Heat-bonded non-woven bag: refers to the addition of fibrous or powdered hot-melt bonded reinforcing material in the fiber web, and the fiber web is further heated, melted and cooled to form a cloth.
3, pulp airlaid non-woven bag: can also be called dust-free paper, dry papermaking non-woven fabric. It adopts the air-laid skill to open the wood pulp fiber board into a single fiber form, and then uses a gas flow method to agglomerate the fiber on the mesh curtain, and the fiber web is further reinforced into a cloth.
4. Wet-laid non-woven bag: the fiber raw material placed in the water medium is opened into a single fiber, and the different fiber raw materials are mixed to form a fiber suspension slurry, and the suspended pulp is transported to a web forming mechanism, and the fiber is in a wet state. Reinforce the cloth into a cloth.
5. Spunbond non-woven bag: After the polymer has been extruded and stretched to form a filament, the filament is laid into a net, and the web is then bonded, thermally bonded, chemically bonded or The mechanical reinforcement method makes the web into a non-woven fabric.
6. Meltblown non-woven bag: The process: polymer feeding---melt extrusion---fiber formation---fiber cooling---forming into the net---reinforcing into cloth.
7. Needle-punched non-woven bag: It is a kind of dry-laid non-woven fabric. The needle-punched non-woven fabric is a puncture effect using a lancet, and the fluffy fiber mesh is reinforced into a cloth.
8. Non-woven non-woven bag: It is a kind of dry non-woven fabric. The stitching method uses warp knitting coil structure for fiber web, yarn layer and non-woven material (such as plastic sheet, plastic thin metal foil, etc.) Or a combination thereof is reinforced to form a nonwoven fabric.
