<p>A water permeability improver for textile materials which comprises at least one member selected from among (a) esters of alkoxylated ricinoleic compounds and/or hydrogenated derivatives thereof with dicarboxylic acids and (b) mixtures of trialkylglycine derivatives with 10 to 80 % of the component (a), and, if necessary, a nonionic, cationic, anionic or amphoteric surfactant; heat-fusible fibers made by using the improver; and nonwoven fabrics made by using the fibers. The improver can give fibers which can pass through a high-speed card without any trouble and have the properties that when the surfaces of the fibers are wetted with the body fluid, the fluid can immediately permeate the surfaces to thereby recover the dry-touch surfaces and that the body fluid permeability of the fibers is not lowered even when the surfaces thereof are wetted with the body fluid repeatedly. The fibers made by using the improver are high-endurance hydrophilic ones which are reduced in slipperiness and can form fibrous laminates, such as nonwoven fabrics, free from lowering in the strengths. The fibers are also useful for the production of clothlike materials and moldings.</p> |
