    摘要: Manufacturing a spun-dyed para-aramid filament yarn includes (a) preparing a spin dope comprising a para-aramid polymer, at least one dyestuff and concentrated sulfuric acid, (b) spinning the spin dope through a spinneret to obtain spun filaments, (c) coagulating the spun filaments to obtain coagulated filaments, (d) neutralizing the coagulated filaments to obtain neutralized filaments, (e) washing the neutralized filaments to obtain washed filaments, and (f) drying the washed filaments to obtain dried filaments. In step a) the spin dope includes 17.5 to 18.5% by weight of a para-aramid polymer with respect to the weight of the spin dope, and 4 to 15% by weight of the at least one dyestuff with respect to the weight of the para-aramid polymer plus the at least one dyestuff. In step f) the filaments are hold under a tension in a range from 0.2 to 0.8 cN/dtex.

    摘要: The invention relates to cellulosic moldings having very finely distributed zinc pigments after the dry-wet extrusion method. Cellulosic moldings formed in accordance with the inventive methods, compared to unmodified cellulose fibers, have a high degree of whiteness combined with greatly increased UV light absorption and a wash-resistant bactericidal effect, while at the same time having unrestricted textile processability. The cellulosic functional moldings produced according to the invention are particularly suited for use in textiles for clothing, technical textiles, recreation, medicine, and cosmetics.
