摘要:
A bi-component continuous filament has a sheath-core arrangement including a first polymer component forming a sheath and including a polyamide, a polyolefin, or a polyester; a second polymer component forming a core and including a polyamide, a polyolefin, or a polyester; and a binding agent adhering the first polymer component to the second polymer component along a length of the filament such that the filament has a generally uniform cross-sectional shape along the length. The binding agent preferably includes a polyolefin modified by an acid anhydride. Articles made from such bi-component continuous filaments include, for example, bulk continuous filament (BCF) fibers and floor coverings, such as mats, rugs, and carpets.

A spun-dyed polyamide yarn wherein carbon black produced by a furnace method and having an average particle diameter of µm to 20 µm is contained in an amount of 1% to 5% by mass in a polyamide and which has a single fiber fineness of 0.8 dtex to 2 dtex; a false-twisted yarn produced by falsely twisting the spun-dyed black polyamide yarn; a covered elastic yarn, in which the spun-dyed black polyamide yarn or the false-twisted yarn is used as a covering yarn; and hosiery, in which at least one of the spun-dyed black polyamide yarn, the false-twisted yarn and the covered elastic yarn is used in part of a leg portion. Provided are stockings or tights which have a soft texture and are capable of developing a dark black color.

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.
