ABSTRACT:
There is provided a method of producing a nonwoven fabric with a wide bonding window by forming a nonwoven web from a thermoplastic polymer blend including from about 0.5 weight percent to about 25 weight percent of syndiotactic polypropylene and then thermally bonding the nonwoven web by a method such as thermal point bonding, through-air-bonding and ultrasonic bonding. Such a web has a bonding window at least 10.degree. F. wider than that of a similar web without syndiotactic polypropylene. Ideally, the bonding window will extend at least 10.degree. F. below that of a similar web without syndiotactic polypropylene.
