    Abstract: PURPOSE: To simultaneously impart moist and smooth touch characteristics, in a sheet like article wherein a coating layer is provided on the surface of a base material mainly composed of an entangled material of extremely fine synthetic fibers with a specific fineness value or less, by constituting the coating layer of a substance wherein a part of atherocollagen molecule is crosslinked. CONSTITUTION: A sheet like article is constituted by forming one or more coating layer on the surface of a base material. The base material is mainly constituted of an entangled material obtained by applying needle punching or water jet punching to extremely fine fibers with 0.5 denier or less. By this constitution, the base material has flexibility and good surface smoothness and the coating layer can be made thin. The coating layer is formed by applying a soln. containing at least atherocollagen to the surface of the base material and irradiating the coated surface of the base material with ultraviolet rays or γ-rays to crosslink at least a part of an atherocollagen molecule. By this method, heat resistance, chemical resistance and high tensile strength can be imparted to the sheet like article.

    Abstract: PURPOSE: To provide a method and a device for producing a fiber having drastically varying cross-sectional areas and shapes varying within a few centimeter in the longitudinal direction without lowering the molecular weight. CONSTITUTION: In this fiber having varying cross-sectional shapes in the longitudinal direction, a nonoverlapping area factor of >=10% appears at any cross section within 10cm length of the fiber, the cross-sectional area varies along the longitudinal direction of the fiber and the ratio of the minimum cross-sectional area to the maximum cross-sectional area is (0.1-0.9). The method for producing the fiber is to process the fiber by contacting and separating a fiber- processing material with and from a part of the fiber and use a piezoelectric element as the driving source of the fiber-processing material. This device for producing the fiber consists of the fiber-processing material which processes the fiber by contacting it with and separating it from the fiber and the piezoelectric element which is the operation-power source of the fiber-processing material.
