Spunlaced non-woven fabric is sprayed with high-pressure fine water on one or more layers of fiber webs to entangle fibers with each other, so that the web is strengthened and has a certain strength. The obtained fabric is a spunlace nonwoven fabric. Whose non-woven fabric has the following characteristics: 1. Flexible entanglement, does not affect the original characteristics of the fiber, does not damage the fiber; 2. Appearance is closer to traditional textiles than other non-woven materials; 3. High strength and low fluff; 4. High hygroscopicity and fast hygroscopicity; 5. Good air permeability; 6. Soft feel and good drape; 7. Variety of appearance; 8. No need for adhesive reinforcement and washability
The principle of hydroentanglement to strengthen the web is similar to the needling process, but instead of using a needling needle, a plurality of fine water jets generated by high pressure are used to spray the web. After the water jet passes through the fiber web, it is entrusted with the rebound of the net curtain to penetrate the fiber web again. As a result, the fibers in the fiber web are displaced, intersected, entangled and entangled by the high-speed water jets in different directions. Strengthen the web.
