摘要： Spunbond multicomponent filaments and nonwoven webs made from the filaments are disclosed. In accordance with the present invention, the multicomponent filaments contain a crimp enhancement additive. Specifically, the crimp enhancement additive is added to the polymeric component that has the slower solidification rate. The additive enhances crimp, allows for highly crimped filaments to be made at low fiber linear densities, improves the integrity of unbonded webs made from the filaments, and produces webs with improved stretch and cloth-like properties. The additive incorporated into the filaments is a random copolymer of butylene and propylene.

摘要： Spunbond multicomponent filaments and nonwoven webs made from the filaments are disclosed. In accordance with the present invention, the multicomponent filaments contain a crimp enhancement additive. Specifically, the crimp enhancement additive is added to one of the polymeric components in order to accelerate its solidification rate. The additive enhances crimp, allows for highly crimped filaments to be made at smaller deniers, and produces low density webs with improved stretch and cloth-like properties. Specifically, the additive incorporated into the filaments is a nonionic surfactant such as an alkyl ether alkoxylate, a siloxane alkoxylate, an ester of a polyalkylene glycol, a polysaccharide derivative, a glycerol ester, or mixtures thereof.
