Wet wipes come into direct contact with human skin, making microbiological control a primary quality and safety requirement. Spunlace nonwoven production lines used for wet-wipe substrates must comply with cleanroom standards and be equipped with enclosed carding rooms, high-efficiency particulate air (HEPA) filtration systems, and multi-stage reverse osmosis (RO) purified water systems that meet pharmacopeial standards.
At New One Brand-VN Non Woven Co., Ltd., high-sensitivity online metal detectors and intelligent visual fabric-inspection cameras are installed before winding. Each production batch is also tested in a sterile laboratory for aerobic bacteria, molds, and yeasts. These measures ensure that every roll of nonwoven fabric supplied to downstream slitting and wet-solution filling facilities meets the required cleanliness standards.
