Non-woven fabrics are made in a spun-melt process, in which a PLA resin blend is melt-spun into filaments, which are pneumatically drawn and then deposited onto a surface to produce the fabric. The PLA resin includes 1-25% of certain aliphatic or aliphatic-aromatic polyesters that have a number average molecular weight from 4,000 to 70,000 g/mol. |
