Abstract
"FIBRAS MULTICOMPONENTES E PANOS NãO TECIDOS FEITOS A PARTIR DESTAS". Os filamentos ligados por fiação bicomponentes e os panos não tecidos feitos a partir dos filamentos são divulgados. Os filamentos ligados por fiação incluem um polímero de núcleo e um polímero de revestimento. Tanto o polímero de núcleo quanto o polímero do revestimento são feitos principalmente de polímeros de polipropileno. Por exemplo, o polímero do revestimento pode ser um copolímero aleatório de polipropileno e etileno. O etileno pode estar presente no polímero de revestimento em uma quantidade de menos de cerca de 2% em peso. O polímero do núcleo, por outro lado, pode ser um polímero de polipropileno possuindo uma temperatura de fusão maior que o polímero do revestimento."MULTI-COMPONENT FIBERS AND NON-WOVEN CLOTHES MADE FROM THESE". Two-component spin-on filaments and non-woven fabrics made from the filaments are disclosed. Spin-on filaments include a core polymer and a coating polymer. Both the core polymer and the coating polymer are made primarily of polypropylene polymers. For example, the coating polymer may be a random copolymer of polypropylene and ethylene. Ethylene may be present in the coating polymer in an amount of less than about 2% by weight. The core polymer, on the other hand, may be a polypropylene polymer having a higher melting temperature than the coating polymer.
