Abstract

"FIBRA DE POLIPROPILENO E MéTODO PARA O PREPARO DA MESMA". Revela-se uma fibra de polipropileno, que é obtida a partir de um homopolímero de polipropileno isotático com um índice isostático de 90 a 99 % através da fiação por fusão ou através de estiramento após a fiação por fusão, e apresenta dois picos endotérmicos medidos por calorímetro de varredura diferencial (DSC) entre 155 e 170 <198>C. quando ligadas termicamente umas às outras, as fibras são reunidas em panos não-tecidos que apresentam excelente resistência além de serem macias. é possível produzir uma alta qualidade dos panos não-tecidos em máquinas de cardar de alta velocidade com alto rendimento."POLYPROPYLENE FIBER AND METHOD FOR PREPARING THE SAME". A polypropylene fiber, which is obtained from an isotactic polypropylene homopolymer having an isostatic index of 90 to 99% by melt spinning or by stretching after melt spinning, has two endothermic peaks measured by melt. differential scanning calorimeter (DSC) between 155 and 170 <198> C. when thermally bonded together, the fibers are assembled into nonwoven cloths that have excellent strength as well as being soft. high quality nonwoven cloths can be produced on high-speed high-speed carding machines.
