[0002] Spunlace non - woven fabric is that high-pressure micro water flow is sprayed to one or more fiber webs, so that fiber is entangled together, so that fiber web is reinforced and has certain strength, and the fabric obtained is spunlace non - woven fabric. Its fiber raw material source is extensive, can be polyester, chinlon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber etc. Spunlace non - woven process is called jetting or hydroentanglement process, and it is a kind of non - woven fabric processing technology. Spunlace non - woven process produces hydraulic action through continuous spraying of high-pressure water flow. Under this action, arranged fiber starts to surge, displacement and re-arrangement, and mutual entanglement. Fiber web is reinforced and has certain physical and mechanical properties under this action. The mechanism of spunlace reinforcement process is as follows. After fiber web enters spunlace area through net curtain, high-pressure water flow forms continuous "water needle". Water needle is cylindrical, vertically shot to fiber web through spunlace head and water needle plate. In this process, fiber is brought into web bottom from surface by water needle and forms entanglement. After water needle penetration, reflection in different directions is formed, so that fiber web is subjected to penetration of water needle in different directions. Therefore, fiber web receives double action of water column on front and back surfaces in the whole spunlace process, forms entanglement in different directions. This entanglement is random, achieves reinforcement effect, thereby forming spunlace non - woven fabric.
