Spunlace spunlace nonwoven fabric non-woven fabrics spray high pressure fine water jets onto one or more layers of fiber webs to entangle the fibers with each other, so that the webs can be reinforced and have a certain strength. The resulting fabric is the spunlace non-woven fabric. Its fiber raw materials have a wide range of sources, including polyester, nylon, polypropylene, viscose fiber, chitin fiber, superfine fiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber.
The principle of spunlace reinforcement of the web is similar to that of acupuncture, but instead of needles, it uses multiple fine water jets generated by high pressure spunlace jetting the web. After the water jet passes through the fiber web, it is entrusted with the rebound of the curtain to 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 high-speed water jets in different directions. The web is reinforced.
And it has promoted the development and improvement of spunlace technology and the entire nonwoven technology. Spunlace and wood pulp air-laid composite technology. Because the price of wood pulp is much cheaper than the staple fiber commonly used in spunlace, and the fluff pulp has good hygroscopicity and hand feeling, the product made is cheaper than the product with all fibers, and the price is very competitive, but in the process The requirements on the filtration system are very high.
The product can be used as the inner core material of wiper diapers and sanitary napkins. Spunlace and wood pulp air-laid composite equipment. Spunlace and filament spunbond web composite technology. The composite product of this method has both the strength of spunbonded nonwovens and the better absorption performance of short fibers, and is more uniform and softer than spunbonded nonwovens, has the function of water and oil absorption, and has higher strength. It can be used as food wrapping cloth. Decorative cloth and cleaning cloth, etc. The spunlace and spunbond composite equipment includes Flerssner's Aquaspun and Aquasplit. Spunlace and wet-laid composite technology.
