Abstract

FIBRA BICOMPONENTE, E, NÃO TECIDO DE FIAÇÃO CONTÍNUA. São fornecidas fibras bicomponentes com curvatura melhorada. A fibra bicomponente compreende uma primeira região e uma segunda região. A primeira região compreende uma primeira composição de polietileno e a segunda região compreende uma segunda composição de polietileno, sendo que a primeira composição de polietileno tem uma temperatura de cristalização (Tc) maior que uma temperatura de cristalização (Tc) da segunda composição de polietileno. A fibra bicomponente pode ser utilizada para formar um não tecido.BI-COMPONENT FIBER, AND, CONTINUOUSLY SPINNED NON-WOVEN. Bicomponent fibers with improved curl are provided. The bicomponent fiber comprises a first region and a second region. The first region comprises a first polyethylene composition and the second region comprises a second polyethylene composition, wherein the first polyethylene composition has a crystallization temperature (Tc) greater than a crystallization temperature (Tc) of the second polyethylene composition. The bicomponent fiber can be used to form a nonwoven.
