| abstract |
The present invention relates to a process for producing fibers, yarns or yarns comprising a polymer blend consisting of an isotactic polypropylene polymer and an atactic elastic polyolefin polymer main component having a high weight average molecular weight of 100,000 or more and a heat of dissolution of 15 to 16 J / g. The stretchable polymer is present in an amount sufficient to increase elasticity to prevent breakage of fibers, yarns or yarns when used in nonwoven articles. The invention also relates to fibers, yarns or yarns comprising such polymers and nonwoven articles made therefrom. The invention further relates to composite articles comprising fibers, yarns or yarns in combination with adhesive compositions and polymer blends used in such adhesive compositions. |
