PURPOSE:To obtain an acrylic synthetic fiber structure having excellent heat retaining properties, sweat absorbing properties and moisture retention. CONSTITUTION:The surface of a fiber structure comprising a porous acrylic synthetic fiber which is composed of a polymer having acrylonitrile as a main constituent unit and a polymer having miscibility but non-compatibility with the polymer, in which both the polymers exist in a phase separated state, and has 0.05-0.75cm<3>/g voids and <=15m<2>/g surface area A of empty pores is provided with a coating film constituted of a silk fibroin-synthetic polymer. |
