Abstract:
A fiber having a diameter in a range of from 0.1 to 50 denier and comprising:(A) from about 0.1 percent to about 30 weight percent (by weight of the fiber) of at least one ethylene polymer having: i. an I2 melt index less than or equal to 10 grams/10 minutes, and ii. a density of from about 0.85 to about 0.97 grams/centimeters3, and (B) a polypropylene polymer, wherein the ethylene polymer is an ethylene/&agr;-olefin interpolymer having an I2 melt index in the range of about 5 to about 10 g/10 minutes, the density of the ethylene/&agr;-olefin polymer is greater than 0.87 g/cm3, and wherein the fiber is characterized as being thermal bondable at 340 pounds/linear inch (pli) and a bond roll surface temperature in the rage of 127 to 137Â° C.
