POLYESTER ANTIFUME ADDITIVE FOR SPANDEX FIBRE |
摘要 |
<p>Saturated aliphatic polyesters having a repeating unit which has the structural form of a residue of a glycol combined with a residue of a diacid or the form of a residue of a hydroxy acid, the number of carbon atoms in the shortest chain between ends of the residues being in the range of 3 to 10 for the glycol residue and no more than 12 for the diacid residue or for the hydroxy acid residue, provide polyether-based spandex fibers with improved resistance to discoloration induced by exposure to nitrogen dioxide fumes.</p> |
