PURPOSE:To readily obtain the subject product having excellent fiber strength, less unevenness, flexibility, drapability and stretchability by performing a specific treatment to the fiber sheet comprising latently releasable fibers of specific joint-type multicomponent fiber. CONSTITUTION:At first, a fiber sheet is made using latently releasable fibers composed of joint-type multicomponent fiber in which (A) a polymer selected from polyamide, polyester and polyolefin and (B) a polymer selected from polyester elastomer, polyamide elastomer and polyurethane elastomer are mutually joined and at least a part of the joined interface is led to the fiber surface and having releasability of the joined interface releasing with aqueous solution having <=400dyne/cm surface tension. Next, said sheet is treated with an aqueous solution having <=400dyne/cm surface tension and each component is released and divided at said joined interface to afford the aimed product. |
