1.Brief introduction of spunlace nonwoven
Spunlace non-woven fabric is to spray high-pressure fine water flow to one or more layers of fiber web, so that the fibers are entangled with each other, so that the fiber web can be strengthened and has a certain strength, the resulting fabric is spunlace non-woven fabric. Its fiber raw materials come from a wide range of sources, such as polyester, nylon, polypropylene, viscose fiber, chitin fiber, ultra-fine fiber, tencel, silk, bamboo fiber, wood pulp fiber, algae fiber, etc.
2.Main raw material editor
(1) Natural fibers: cotton, wool, hemp, silk;
(2) Conventional fiber: viscose fiber, polyester fiber, acetate fiber, polypropylene fiber, polyamide fiber;
(3) Differentiated fibers: ultra-fine fibers, shaped fibers, low-melting-point fibers, high-crimp fibers, antistatic fibers;
(4) High-functional fibers: aromatic polyamide fibers, carbon fibers, metal fibers.
3.Principle of processing
The principle of the spunlace reinforcement web is similar to the needling process, but instead of the needling needle, multiple fine water jets generated by high pressure are used to jet the fibrous web by the spunlace machine. After the water jet passes through the fiber web, it is supported by the rebound of the mesh curtain, and the fiber web is inserted again. As a result, the fibers in the fiber web are displaced, interspersed, entangled, and huged by the hydraulic force of the high-speed water jet interspersed in different directions, thereby Reinforce the web.
The use of spunlace non-woven fabrics is for medical curtains, surgical gowns, surgical covers, medical dressing materials, wound dressings, medical gauze, aviation wipes, clothing lining cloths, coated base cloths, disposable China Kitchen Wipes Material, and advanced wipes for instruments and meters , Advanced rags, towels, cotton pads, wipes, mask covering materials for the electronics industry, etc.
China's spunlace nonwoven fabric production line has developed rapidly. Among them, Jiangsu and Zhejiang provinces are the most prominent. Especially after the economic crisis, the spunlace nonwoven industry has not only been unaffected, but has bucked the trend. The industry is extremely hot, adding dozens of water Barbed wire.
