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 heat-insulating dark cool-feeling textile and a dark cool-feeling fiber thereof are provided. The dark cool-feeling fiber is formed by adding to the fiber nano microparticles which account for 0.05-5 wt % of the total weight of the textile fiber. The particle size of the nano microparticles is 300-1,800 nm, and the material of the nano microparticles is selected from two or more of iron, copper, nickel, cobalt, and chromium. The dark cool-feeling fiber is suitable for knitting or weaving to obtain a heat-insulating dark cool-feeling textile.
