摘要

Fine fibers cah be produced on a long spin line using met-allocene isotactic PP. Fibers in the dtex range of 2.2-1.0 have been characterized to present data with respect to general fiber properties, bonding properties by calender bonding, as well as nonwoven tensile and barrier properties. The main differences and advantages for the metallocene PP fibers compared to standard zniPP fibers can be summarized as follows: 1. Fiber fineness in the range of 1.5-1.0 dtex are feasible 2. miPP fibers have higher tenacity than zniPP fibers, and tenacities on the order of 7-8 cN/dtex have been obtained 3. Good thermal bonding properties for calender bonding are possible 4. Improved nonwoven uniformity and coverage is realized 5. A substantial reduction of nonwoven pore sizes can be achieved 6. Fabric softness will be improved as well. Applications for fine fibers should be numerous within the hygiene industry as well as for the technical fiber area. Work is ongoing to evaluate the possibilities and to introduce the fibers. The metallocene technology is still being developed and is expected to result in further improved properties, which will be beneficial to production and application of staple fibers.
