  • High strength nonwoven web from a biodegradable aliphatic polyester
    Patent number: 7994078
    Abstract: The present invention provides a nonwoven web prepared from an aliphatic polyester polymer which has sufficient tear strength and is biodegradable. Biodegradable nonwoven webs of the present are prepared from a polymer blend having from about 65% by weight to about 99% by weight of a biodegradable aliphatic polyester polymer and from about 1% by weight to about 35% by weight of a second polymer selected from the group consisting of a polymer having a lower melting point than the biodegradable aliphatic polyester polymer, a polymer having a lower molecular weight than the biodegradable aliphatic polyester polymer and mixtures thereof. Surprisingly, the nonwoven webs of the present invention have a tear strength greater than the tear strength of a nonwoven web prepared from the biodegradable aliphatic polyester polymer alone.
    Type: Grant
