What are the types of non-woven bags according to the production process?

Update:18 Jul 2022
1. Spunlace: The high-pressure fine water flow is sprayed onto one or more layers of fiber webs, and the non-woven bag manufacturers introduce that the fibers are entangled with each other by heat-sealing the non-woven bag, so that the fiber web can be reinforced and have a certain strength; pulp; Meal airlaid non-woven bag: also known as dust-free paper, dry-laid non-woven fabric. The wood pulp fiberboard is opened into a single fiber state by air-laid technology, and then the fibers are aggregated on the web-forming curtain by the air-laid method, and the fiber web is reinforced into cloth.

2. Wet-laid non-woven bag: The fiber raw material placed in the water medium is opened into single fibers, and different fiber raw materials are mixed at the same time to make fiber suspension pulp, and the suspension pulp is transported to the web-forming mechanism. It is formed into a net and then reinforced into cloth; heat-sealed non-woven bag: refers to adding a fibrous or powdery hot-melt adhesive reinforcement material to the fiber web, and the fiber web is then heated, melted, cooled and reinforced into cloth; acupuncture: it is a dry method A kind of non-woven fabric, needle-punched non-woven fabric is to use the puncture effect of the needle to reinforce the fluffy fiber web into cloth.

3. Spunbond non-woven bag: 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, chemically bonded or mechanically bonded. Reinforcement method to make fiber web into non-woven fabric; Meltblown non-woven bag process: polymer feeding--melt extrusion--fiber formation--fiber cooling--forming web--reinforcing into cloth; stitchbonding : It is a kind of dry-laid non-woven fabric. The stitch-bonding method is to use the warp-knitted coil structure to reinforce the fiber web, yarn layer, non-woven material or their combination to make a non-woven fabric.
