ALIPHATIC POLYESTER MELT-BLOWN NONWOVEN FABRIC AND ITS PRODUCTION

摘要

PURPOSE:To industrially stably produce aliphatic polyester melt-blown nonwoven fabric excellent in shape stability, heat sealability and high physical properties, reducing environmental pollution and capable of being used as a raw material suitable for uses such as packaging materials and daily miscellaneous goods. CONSTITUTION:The aliphatic polyester melt-blown nonwoven fabric produced by melt-blowing mixed polymers comprising 75-98wt.% of an aliphatic polyester and 25-2wt.% of a polyolefin polymer under the condition of a blown air pressure of 0.1-1.0kg/cm<2>.
