The parallel lapping technology is the most traditional way of forming a web for spunlaced non-woven fabrics. By using one or two parallel carding machines to card fibers into a web, and then reinforcing the fiber web with high-pressure water, a fluffy and soft spunlaced nonwoven fabric is obtained. Parallel spunlace nonwoven fabric is widely used in wet wipes for baby, adults, pets, makeup removal, disinfection, household cleaning, industrial wiping, etc. It is also used for covering the core of diapers, protective clothing, and other products.
