Polyester heat bonded product |
摘要 |
Disclosed is a nonwoven fabric which is a nonspunbonded fabric and has a surface free of standing fibers and a method for making the same. The fabric is useful as a support for case on coatings to form a composite for TFC membrane filters. The fabric is formed of a first layer having binder fiber and matrix fiber. A second layer of 100 percent binder fiber is cast thereon. The binder fiber has a softening point lower than the melting point of the matrix fiber. The first and second layers are bonded by heat and pressure to form the fabric.
