摘要： Provided are melt-spun fibers comprising, as at least one component, a water-soluble polyvinyl alcohol, and a method for producing fibrous structures comprising the fibers. The thermoplastic polyvinyl alcohol fibers comprise, as at least one component, a water-soluble polyvinyl alcohol containing from 0.1 to 25 mol% of C1-4 α-olefin units and/or vinyl ether units, having a molar fraction, based on vinyl alcohol units, of a hydroxyl group of vinyl alcohol unit located at the center of 3 successive vinyl alcohol unit chain in tens of triad expression of being from 70 to 99.9 mol% , having a carboxylic acid and lactone ring content of from 0.02 to 0.15 mol%, and having a melting point falling between 160°C and 230°C, and contain from 0.0003 to 1 part by weight, relative to 100 parts by weight of the polyvinyl alcohol therein and in terms of sodium ion, of an alkali metal ion.

摘要： To provide an electrically-conductive composite fiber which does not suffer component separation during spinning, retains its good initial conductive performance for a long period of time, and exhibits good color fastness. The electrically-conductive composite fiber is composed of an electrically-conductive polyamide layer (A) containing 15-50 wt% of electrically-conductive carbon black and a protective polymer layer (B) of polyamide of specific composition, wherein said electrically-conductive polyamide layer (A) exposes itself at the fiber surface such that the number of exposed parts is 3 or more and the length (L 1 µm) of one exposed part along the periphery of a cross section satisfies the expression below, and said protective polymer layer (B) covers not less than 60% of the periphery of the fiber cross section and accounting for 50-97 wt% of the total fiber weight. 0.1 ≤ L 1 ≤ L 2 /10 (where L 2 stands for the length (in µm) of the periphery of a cross section of one filament.)
