Characteristics and types of Wenzhou Xinyu nonwovens
The exact name of non-woven fabrics should be non-woven fabrics, or non-woven fabrics. Because it is a kind of fabric that does not need spinning and weaving, it just orientates or randomly spun short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.
Characteristics of non-woven fabrics Non-woven fabrics break through the traditional textile principle, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many sources of raw materials.
Types of non-woven fabrics According to the different production processes, non-woven fabrics can be divided into:
(1) Spunlace non-woven fabric: It is to spray high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs are reinforced and have a certain strength.
(2) 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, melted, cooled, and reinforced into a cloth.
(3) Pulp airlaid non-woven fabrics: also known as dust-free paper and dry-laid non-woven fabrics. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to condense the fibers on the web-forming curtain, and the fiber web is reinforced into a cloth.
(4) Wet-laid non-woven fabrics: the fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to make fiber suspension pulp. In the wet state, it is formed into a web and then reinforced into a cloth.
(5) Spunbond non-woven 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, chemically bonded Combination or mechanical reinforcement methods to turn the web into a non-woven fabric.
(6) Melt-blown non-woven fabric: its technological process: polymer feeding --- melt extrusion --- fiber formation --- fiber cooling --- web formation --- reinforcement into cloth.
(7) Needle-punched non-woven fabric: It is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric is to use the puncture effect of needles to reinforce the fluffy fiber web into cloth.
(8) Stitch-bonded non-woven fabric: introduced by Wenzhou Xinyu Non-woven Fabric Co., LTD. Plastic thin metal foils, etc.) or their combinations are reinforced to make non-woven fabrics.
