Patent number: 5540976Abstract: There is provided a nonwoven fabric laminate having cross-directional stretch properties. The laminate is comprised of at least three layers. The outer layers are spunbond nonwoven fiber webs which are made of crimped or crimpable fibers. The inner layer is an elastomeric polymer layer which may itself be composed of one or more thinner layers. The layers are preferably produced by sequentially depositing them onto a moving forming wire and bonding them together by a method excluding hydroentanglement to form the laminate.Type: GrantFiled: January 11, 1995Date of Patent: July 30, 1996Assignee: Kimberly-Clark CorporationInventors: Susan E. Shawver, Leslie W. Collier, IV, Paul W. Estey

Patent number: 5204174Abstract: There is disclosed a nonwoven web consisting of highly drawn and unoriented thermoplastic fibers formed from a blend of propylene polymer and butylene polymer, wherein the blend by weight is from 90% to 50% polypropylene and from 10% to 50% polybutylene. The blend can be a blend of a homopolymer of polypropylene and a homopolymer of polybutylene; a homopolymer of polypropylene and a copolymer of butylene; a copolymer of propylene and a homopolymer of polybutylene; and a copolymer of propylene and a copolymer of butylene. In addition ternary blends (homopolymers of polypropylene, copolymers of propylene and butylene, terpolymers (propylene, 1-butene, and ethylene), and blends of terpolymers with polypropylene are useful. The resulting nonwoven webs have enhanced toughness, tear resistance, drape, and conformability.Type: GrantFiled: May 4, 1990Date of Patent: April 20, 1993Assignee: Kimberly-Clark CorporationInventors: Diego H.
