Modified polypropylene fibre and other polypropylene products and method of obtaining them |
摘要 |
Modified fibres and other polypropylene products like film, nets and casings were invented with unique properties like elasticity softness and improved dye - affinity. These fibres and other products are made from a blend of standard commodity polypropylene and an elastomer. The used elastomer is a branched copolymer of ethylene and / or a polyolefin copolymer with ethylene and / or higher alkene groups in the main chain. The elastomer is characterized by following properties: melting point - not lower than 80 DEG C, melt flow index 1 to 60 g/ 10 min, density within 0.85 - 0.95 g/cm<3>. The weight proportion of propylene to the elastomer ranges from 99.9 : 0.1 to 0.1 : 99.9. The products like fibres, film, nets and casings are formed from the blend of granulates by known - manufacturing methods. |
