Abstract

A thermally bonded fibrous wet laid web containing a bicomponent fiber including a polyester or polyamide fiber component and a component consisting of a linear low density polyethylene having a density in the range of 0.88 to 0.945 g/cc. A grafted HDPE can be added to the LLDPE to improve adhesion of the bicomponent fiber. The bonded fibrous wet laid web may further include a matrix fiber selected from the group consisting of cellulose paper making fibers, cellulose acetate fibers, glass fibers, polyester fibers, ceramic fibers, mineral wool fibers, polyamide fibers, and other naturally occurring fibres. It has been found that a thermally nonwoven fibrous web made using the foregoing ingredients has improved and unexpected strength, lower web variability and is softer.
