An object of the present invention is to provide an antiviral fiber assembly in which an antiviral agent is retained with chemical stability over a long period of time, and which is gentle to the human body. A further object of the present invention is to provide a fiber assembly with cellulose sulfate that can exhibit sufficient antiviral activity over a long period of time. Further, another object of the present invention is to provide a textile product obtained using such a fiber assembly. The present invention provides a fiber assembly with cellulose sulfate, wherein the hyaluronidase inhibitory activity is 50% or higher; and a process for producing a fiber assembly with cellulose sulfate, including treating a fiber assembly with an aqueous cellulose sulfate solution and drying, then treating the same with a pH buffer solution and drying.

Antiviral fiber assembly with cellulose sulfate

A splittable conjugate fiber comprising a polyester segment and a polyolefin segment, wherein the splittable conjugate fiber comprises two or more parts of the polyester segment extending from a center of the fiber toward an outer edge of the fiber in a cross-sectional configuration perpendicular to its longitudinal direction, in which at least one of the two or more parts of the polyester segment extending from the center of the fiber toward the outer edge of the fiber is exposed at the outer edge of the fiber and at least one of the two or more parts of the polyester segment extending from the center of the fiber toward the outer edge of the fiber is unexposed at the outer edge of the fiber.

Splittable conjugate fiber, aggregate thereof, and fibrous form made from splittable conjugate fibers

There is provided an antibacterial and deodorant fiber that exhibits excellent inhibition of bacterial growth, is capable of responding to a wide variety of odorants, does not discolor easily, and can maintain stable performance. An antibacterial and deodorant fiber characterized in that a fiber treatment agent comprising at least a component (A), and a component (B) and/or a component (C) below are attached thereto at 0.2 to 5 wt % of the total weight of the fiber, the fiber treatment agent containing 20 to 80 wt % of the component (A), and 80 to 20 wt % of the component (B) and/or the component (C):

Antibacterial and deodorant fiber, fiber formed article, and fiber product

A thermal bonding conjugate fiber constituted from a first component comprising a polyester resin and a second component comprising a polyolefin resin with a melting point lower than that of the polyester resin by not less than 20&#xb0; C., characterized in that a post-heat treatment bulk retention rate thereof is 20% or more when calculated by the following measurement method: Bulk retention rate=(H1 (mm)/H0 (mm))&#xd7;100(%) (wherein H0 is the web height when a 0.1 g/cmload is applied to a web with a mass per unit area of 200 g/m; and H1 is the web height after a heat treatment for 5 min at 145&#xb0; C. when a 0.1 g/cmload is applied to that web).
