摘要： A material for a primary carpet backing comprising a nonwoven fabric comprising first bicomponent core/sheath fibers comprising a first thermoplastic polymer in the core and a second thermoplastic polymer in the sheath and second bicomponent core/sheath fibers comprising a third thermoplastic polymer in the core and a fourth thermoplastic polymer in the sheath, wherein the first thermoplastic polymer in the core of the first bicomponent core/sheath fibers is of a different polymer family as the third thermoplastic polymer in the core of the second bicomponent core/sheath fibers, and wherein the second thermoplastic polymer in the sheath of the first bicomponent core/sheath fibers and the fourth thermoplastic polymer in the sheath of the second bicomponent core/sheath fibers are polymers of the same polymer family, preferably having the same melting temperature.
