Description du produit


SMS nonwoven fabrics is made form Polypropylene, There are tri-layer, spunbond + meltblown + spunbond nonwoven. Through special treatment, SMS nonwoven fabric own many special features, such as Medical Repellence(anti-alcohol, anti-blood,anti-oil)grade, Anti-static, Anti-mildew and anti-bacterial, Extrasoft,Hydrophilic, etc. We can produce 14-200gsm SMS nonwoven fabric. It wildly applied in the medical, hygiene, industry fields, such as isolation gowns, patient gowns, wound care, laboratory apparel, procedure gowns,surgical drape, caps and facemask. Leg cuff of baby diaper and adult inconvenience diaper, etc.

What is the SMS nonwoven SMS (English as: Spunbond + Meltblown + Spunbond Nonwovens)
