摘要： A method includes charging PET bottle flakes having particular characteristics as a raw material into a crystallizer to generate a crystalline version thereof, drying the crystalline version with dehumidified air at a temperature of 160-180° C. and with a dew point of −40° C. to bring down a moisture level thereof below 100 ppm, melting the dried crystalline version through an extruder configured to have a temperature therein maintained at 285-295° C., and feeding the melted raw material into a spin beam. The method also includes generating, through a spinneret, a number of filaments based on extruding, through the spinneret, the melted raw material fed into the spin beam, forming a yarn based on combining the number of filaments, and winding the formed yarn to generate a spool of Partially Oriented Yarn (POY) configured to be utilized as another raw material to generate a Draw Texturized Yarn (DTY).

摘要： A dyeing and welding process may be configured to convert a substrate into a welded substrate having at least some color imparted thereto via a dye and/or coloring agent by applying a process solvent having a dye and/or coloring agent therein to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may include a binder, such as dissolved biopolymer (e.g., cellulose). After application of a process solvent comprised of a dye and/or coloring agent, the substrate may be exposed to a second application of a process solvent comprised of a binder, which second application may occur before or after a process temperature/pressure zone, process solvent recovery zone, and/or drying zone.

摘要： A thread accumulation device includes a discharge chute (13) for receiving and guiding a strand that is formed by a thread take-up device and a carriage for taking up a thread spiral, guided on the discharge chute (13) and resting on the end of the strand of the side that is opposite to the thread take-up device. At the outlet of the thread take take-up device, the discharge chute (13) is equipped with a transport unit (16) that adapts to the inside shape of the discharge chute (13). The invention can be applied more particularly in the field of the textile industry, in particular the treatment of thread.

摘要： The instant invention relates to a compression bar such as is used in the main drafting zone of drafting rollers of the textile industry. The invention considerably reduces deposits on a compression bar. The fixed compression bar has a rectangular cross-section, with its narrow faces being rounded off. On the other hand, the compression bar is rotatably mounted about its longitudinal axis, whereby the compression bar has preferably a circular cross-section.

摘要： The present invention provides a production process characterized in that a false twisting process is added between a spinning process and a winding process so that yarn slivers undergo excessive pre-torsion in an axial direction and twists which are same in quantity but different in twisting direction are generated on the yarn slivers. Absorption of glucose-containing sulfur dyestuff is performed in a dyeing process. An ammonia removal process is performed in a high-temperature and high-pressure tank so that residual ammonia in a fabric is evaporated. The evaporated ammonia is collected and then fed back to a mercerizing process for continuous use. The present invention also provides a production line including a spinning unit having a false twisting device, a dyeing unit configured to realize the dyeing process, and a liquid ammonia finishing unit consisting of a fabric mercerizing device, an ammonia removal device, an ammonia recycling device and a controller.

摘要： The described incandescent tension annealing processes involve thermally annealing twisted or coiled carbon nanotube (CNT) yarns at high-temperatures (1000° C. to 3000° C.) while these yarns are under tensile loads. These processes can be used for increasing yarn modulus and strength and for stabilizing both twisted and coiled CNT yarns with respect to unwanted irreversible untwist, thereby avoiding the need to tether torsional and tensile artificial muscles, and increasing the mechanical loads that can be moved by these muscles.

摘要： A method of forming carded fibers of different materials. A feed system has a plurality of separate laterally spaced chambers containing fibers of different materials. The different fibers are fed in separate laterally spaced paths into a carding apparatus having a plurality of rollers and cylinders each having laterally spaced sections in alignment with the laterally spaced paths to receive and maintain the different fibers in the laterally spaced paths thereon as they move through the carding apparatus. The different fibers are combined into a multi-fiber roving or web after they exit the carding apparatus. Depending on the composition of the different fibers, they may be combined by conveying them through a humidifying and heated chamber or chambers.
