The present invention belongs to the technical field of textile yarn storage, and specifically discloses a yarn storage device for a textile machine for textile use, comprising a bottom plate, two support plates are fixedly connected to the top of the bottom plate, a winding structure is arranged between the two support plates, an auxiliary structure located at the center of the support plates is arranged between the two support plates, a yarn sorting structure is arranged on the surface of the support plates, and a notch is opened on the surface of one of the support plates. By arranging the winding structure, the air flow can flow to the inside of the yarn collecting drum during the rotation of the yarn collecting drum through the mutual cooperation of the fan, the connecting hole and the adsorption hole during the winding process, thereby reducing the uneven distribution of the yarn collected caused by the yarn position deviation caused by the outward flow, and generating an adsorption force at the same time to make the yarn winding more stable, and the setting of the adsorption channel can make the connection more stable through the adsorption block of the adsorption channel, so that the process of winding the yarn is more stable.

This invention belongs to the field of weaving equipment technology and discloses a pretreatment device for a circular loom, including a housing with multiple ferrules installed at the bottom. One end of the housing is fixedly installed with an inlet plate having multiple inlet guide holes. Inside the housing, along the yarn travel direction, are sequentially arranged an infrared heating tube group, an atomizing nozzle group, a parallel electrode plate, a simulated weaving guide roller group, a low-temperature plasma generator, a heated pressure roller group, and a cold air cooling unit. The other end of the housing is fixedly installed with an outlet plate having multiple outlet guide holes. This device integrates multiple pretreatment functions into one housing, realizing integrated continuous operation of yarn pretreatment. It can effectively release internal yarn stress, remove surface fuzz from the yarn, improve yarn flexibility and surface quality, thereby reducing the shrinkage rate of the base fabric, reducing yarn breakage during weaving, improving the production efficiency and product quality of the circular loom, and reducing production costs.

Provided are: a cellulose fiber manufacturing method for suppressing the occurrence of thread breakage in a spinning step and unevenness in the physical properties of obtained fibers, thus enabling stable spinning; and cellulose fibers that are highly strengthened, in which fibrillation is suppressed, and that have a pleasant texture. The present invention provides a cellulose fiber manufacturing method including the following steps: a solution preparation step for dissolving cellulose in a mixed solvent of an aprotic polar solvent and a quaternary onium salt; a discharge step for discharging the obtained solution in a fibrous form through a spinneret, the moisture content of the solution at the time of discharging falling within the range from 0.05 mass% to 8 mass%; and a solidification step for solidifying the discharged fibers in a water-based solidification bath containing water and the mixed solvent.
