The joint venture of BBAFiberweb and DowChemical has developed a new type of spunbond elastic nonwoven fabric . The fiber is a sheath-core bicomponent fiber, the core layer is an elastomer, and the skin layer is a polymer with good extensibility. The different proportions of the two components make the resulting spunbond nonwoven fabric have very good elasticity, lower modulus of elasticity, and higher strength and dimensional stability, which makes durable clothing for spunbond nonwoven fabric Offers the possibility.
