Abstract

PURPOSE: Synthetic fiber in which the cross section is made gearlike and a functional additive is applied to the depression parts, thus preventing the change in touch caused by the treatment with the functional additive and keeping the function permanently.
CONSTITUTION: For example, two or more kinds of polymers that or different from one another in hydrolyzability are melt spun into conjugate fiber with a multilayered cross section as shown in the figure. The resultant fiber is hydrolyzed with an aqueous alkali solution to remove more part of polymer 3 that is higher hydrolyzable than other polymers and form depression parts like a gear, preferably continuing along the fiber axis. Then, a functional additive for fiber such as antistatic agent, sweat-absorbing agnent of antistaining agent is applied to the surface in the depression parts to produce the objective fiber. An example of highly hydrolyzable polymer is a polyester containing -SO3Me (Me is metallic element) and the one of low hydrolyzability is polyethylene terephthalate.
