The principle of spunlace reinforcement is similar to that of acupuncture, but instead of needles, it uses multiple fine water jets generated by high pressure---spunlace jets to spray the web.
After the water jet passes through the fiber web, it is entrusted to hold the bounce of the curtain and intersect the fiber web again.
As a result, the fibers in the fiber web are displaced, interspersed, entangled and entangled under the hydraulic action of the high-speed water jets in different directions. The web is reinforced.
