TEREPHTHALATE-BASED SULFOPOLYESTERS |
| 摘要 |
This invention relates to water-dispersible sulfopolyesters comprising residues of (i) terephthalic acid; (ii) an amount sufficient to provide water-dispersibility to the sulfopolyester of at least one difunctional sulfomonomer containing at least one sulfonate group bonded to an aromatic ring; (iii) less than 5 mole % of at least one dicarboxylic acid that is not terephthalic acid or a sulfomonomer; (iv) 25 to 90 mole % of at least one polyethylene glycol having the structure: H-(OCH2CH2)n-OH wherein 2 </=n < 20 with the proviso that the mole % of the polyethylene glycol is inversely proportional to the quantity n within the range; and (v) from greater than 10 to less than 75 mole % of hydroxyl equivalents of a glycol or mixture of glycols that is(are) not a polyethylene glycol. The water-dispersible sulfopolyesters according to the invention exhibit improved abrasion and blocking resistance when used as sizing compositions. Accordingly, in another embodiment the invention relates to a fibrous article sized with a sizing composition comprising a water-dispersible sulfopolyester as described above and method of making same.
