Thermoplastic polyvinyl alcohol fibers and method for producing them |
摘要 |
Provided are melt-spun fibers comprising, as at least one component, a water-soluble polyvinyl alcohol, and a method for producing fibrous structures comprising the fibers. The thermoplastic polyvinyl alcohol fibers comprise, as at least one component, a water-soluble polyvinyl alcohol containing from 0.1 to 25 mol% of C1-4 alpha -olefin units and/or vinyl ether units, having a molar fraction, based on vinyl alcohol units, of a hydroxyl group of vinyl alcohol unit located at the center of 3 successive vinyl alcohol unit chain in tens of triad expression of being from 70 to 99.9 mol% , having a carboxylic acid and lactone ring content of from 0.02 to 0.15 mol%, and having a melting point falling between 160 DEG C and 230 DEG C, and contain from 0.0003 to 1 part by weight, relative to 100 parts by weight of the polyvinyl alcohol therein and in terms of sodium ion, of an alkali metal ion. |
