Systems for producing M yarns, wherein M1, include N extruders, M spin stations, and a processor, wherein N>1. Each extruder includes a polymer having a color, hue, luster, and/or dyeability characteristic, which are different from each other. Each spin station produces one yarn comprising at least one bundle of filaments. Each spin station comprises at least one spinneret through which filaments are spun from at least two molten polymer streams received by the respective spin station and N spin pumps upstream of the spinneret for the respective spin station. Each spin pump is paired with one of the N extruders. The processor is in electrical communication with the N*M spin pumps and is configured to adjust the volumetric flow rate of the polymers pumped from each spin pump to achieve a ratio of the polymers to be included in each M yarn.

A method of manufacturing bulked continuous carpet filament which, in various embodiments, comprises: (A) grinding recycled PET bottles into a group of flakes; (B) washing the flakes; (C) identifying and removing impurities, including impure flakes, from the group of flakes; (D) passing the flakes through a PET crystallizer; (E) passing the group of flakes through an MRS extruder while maintaining the pressure within the MRS portion of the MRS extruder below about 18 millibars; (F) passing the resulting polymer melt through at least one filter having a micron rating of less than about 50 microns; and (G) forming the recycled polymer into bulked continuous carpet filament that consists essentially of recycled PET.

A garment for therapeutic comfort to the wearer's lower body. The garment includes an outer layer that is usually of color or design in order to be aesthetically pleasing, and an inner layer that is in contact with the wearer when worn. The garment includes a plurality of upper and lower pocket members selectively positioned on the front, rear, outer, and inner sides of the garment, the pocket members each include a chamber in communication with an opening that can be in parallel or perpendicular with the length of leg portions of the garment. Each of the pocket members are defined between the outer and inner sides of the garment, and are seized for receiving a cold compression.

A multicolored and accented carpet includes a plurality of tufts of color accented fiber including two or more differently colored extruded solution dyed yarns and a base yarn twisted together whereby a plurality of color transitions are provided along the length of the single accented fiber. A cut pile carpet is produced, having the appearance of a space dyed carpet, with the fade and bleach resistance of a solution dyed carpet.

An object of the present invention is to provide a carpet exhibiting excellent antifouling property against both dry soil and wet soil. The carpet is a carpet including a pile yarn having a coated pile single yarn, in which the coated pile single yarn is a pile single yarn to which a layer A containing organopolysiloxane and a fluorine-based compound is attached, a fineness of the coated pile single yarn is 8 to 40 dtex, a crimp elongation of the pile yarn is 10% to 30%, a carpet staining degree (E) in an antifouling dry test is 30 or less, and a carpet staining degree (E) in an antifouling wet test is 30 or less.

A multicolor carpet comprising a plurality of tufted yarns, wherein the yarns comprise solution-dyed bulked continuous filaments, wherein at least one of the yarns is of a different color than any of the other yarns, wherein the yarns have not been twisted, and wherein the yarns have not been heatset.

A method of manufacturing a wool-like yarn from continuous filaments of polymer material comprises steps of: providing partially oriented, continuous filaments of the polymer; drawing and air texturizing the partially oriented filaments to form threads, wherein a first group of straight filaments forms a core of the thread and a second group of filaments are overfed with respect to the first group of filaments to form a hairy sheath; and twisting or cabling a plurality of the threads together to form the wool-like yarn to have a weight of greater than 2000 dtex. The resulting wool-like continuous filament yarn is intrinsically UV resistant, antistatic and recyclable.

A method of manufacturing high bulk continuous multi-filament yarn comprises a number of distinct steps. In a first step, a plurality of filaments of polymer are melt spun to form a partially oriented yarn (POY). In a second step, the POYs are drawn and textured to form a draw textured yarn, wherein texturing is carried out in a friction texturing process. Subsequently at least two plies of the draw textured yarn are twisted and/or cabled together and subsequently heat set to obtain the high bulk continuous multifilament yarn.

The present disclosure provides a polyamide 5 staple fiber, a preparation method and use thereof. The polyamide 5 staple fiber has a denier of 8.0-30.0D, a breaking strength of 2.0-6.0 cN/dtex, and an elongation at break of 30-100%. The polyamide 5 staple fiber has good mechanical properties and softness, and a blended wool yarn for manufacturing carpets with good mechanical properties, dyeability, and wear resistance can be obtained by using the polyamide 5 staple fiber.
