Dreidimensionale Polymer-Vliese und Verfahren zu ihrer Herstellung

Three-dimensional nonwoven webs comprise at least one layer consisting of drawn and unoriented thermoplatic fibers formed from a blend of polypropylene and polybutylene, wherein the blend by weight is from 90% to 70% polypropylene and from 10% to 30% polybutylene. The blend can be a blend of a homop...

More Information
Summary:Three-dimensional nonwoven webs comprise at least one layer consisting of drawn and unoriented thermoplatic fibers formed from a blend of polypropylene and polybutylene, wherein the blend by weight is from 90% to 70% polypropylene and from 10% to 30% 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 polybutlene: a copolymer of polypropylene and a homopolymer of polybutylene: and a copolymer of polypropylene and a copolymer of polybutylene. In addition, ternary blends comprising polypropylene, polybutylene and a terpolymer (propylene, ethylene, and l-butene) are disclosed. The resulting nonwoven webs have high strength, toughness, and tear resistance.
