Abstract: Methods and systems of the present invention use mixed textile feedstock, which may include post-consumer waste garments, scrap fabric and/or other textile materials as a raw feed material to produce isolated cellulose and other isolated molecules having desirable properties that can be used and be used in the textile and apparel industries, and in other industries. A multi-stage process is provided, in which mixed textile feed material is subjected to one or more pretreatment stages, followed by at least two pulping treatments for isolating cellulose molecules and other molecular constituents, such as polyester. The isolated cellulose and polyester molecules may be used in a variety of downstream applications. In one application, isolated cellulose and polyester molecules are extruded to provide regenerated cellulose fibers and regenerated polyester fibers having desirable (and selectable) properties that are usable in various industrial applications, including textile production.

Abstract: A method for improving the quality of a polyester industrial yarn is provided. First, in the cooling process of preparing a polyester industrial yarn prepared by polyester spinning, the longitudinal height is kept unchanged, and the cross-sectional area of the slow cooling chamber is enlarged. The chamber maintains the surface temperature of the spinneret by means of heat preservation, and then uses an oil agent containing 67.30-85.58 wt % crown ether in the oiling process of polyester industrial yarn prepared by polyester spinning. Enlarging the cross-sectional area of the slow-cooling chamber refers to the cross section of the slow cooling chamber is changed from a circular shape to a rectangular shape while keeping the spinneret connected to the slow cooling chamber unchanged. The cleaning cycle of the spinneret is prolonged by 35-45%, the full package rate of polyester industrial yarn is larger than 99%.
