What Is Spunlace Nonwoven Fabric

May 30, 2018

Spunlaced nonwovens fabric are high-pressure micro-jets that are sprayed onto one or more layers of fiber webs to entangle the fibers with each other so that the web is reinforced and has a certain strength. The resulting fabric is a spunlace nonwoven. The fiber raw materials are widely available and can be polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber and the like.

The principle of the spunlaced reinforcement of the web is similar to that of the needling process. Instead of using a puncture needle, multi-stranded micro-water jets produced by high pressure are used to inject the web. After the water jet passes through the web, it is held back by the bounce of the net curtain, and then interpenetrates the web again. As a result, the fiber in the web undergoes displacement, interpenetration, entanglement, and cohesion under the action of high-speed water jets interleaving in different directions. Reinforce the web.
