PRODUCTION OF MELT-BLOW NONWOVEN FABRIC MADE OF FIBER HAVING SEA-ISLAND STRUCTURE

摘要

PURPOSE:To stably produce a uniform melt-blow nonwoven fabric having low shot (polymer lump) content by using fine fibers having a longitudinally continuing sea-island structure. CONSTITUTION:This process for the production of a melt-blow nonwoven fabric composed of fibers having a sea-island structure comprises the mixing of incompatible polymers satisfying the formula 2<= delta<8 ( delta is difference of solubility parameters of the blending polymers) and the formula log0.3
