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: The present disclosure relates to methods and systems for recovering and repolymerizing textile fibers. Textile fibers, such as those containing cellulose or elastomers, can undergo multiple rounds of recovery and regeneration. During the regeneration process, the textile fibers are isolated from non-desired material, repolymerized or reformed, and then extruded to form a second set of textile fibers. The degree of polymerization of the textile fiber decreases with each regeneration cycle. Regeneration and production can be repeated any appropriate number of times until the regenerated textile fibers do not have the necessary or appropriate degree of polymerization for textile production.

Abstract: The present disclosure relates to methods and systems for producing paper or packaging products. A combination pulp is formed by combining textile pulp and wood pulp and processed to produce the paper or packaging products. The textile pulp and wood pulp can be combined in a given ratio based on their respective characteristics or parameters to obtain a combination pulp with a desired characteristic or parameter.

Abstract: Methods and systems of the present invention use cellulose-containing materials, which may include post-consumer waste garments, scrap fabric and/or various biomass materials as a raw feed material to produce isolated cellulose molecules that can be used in the textile and apparel industries, and in other industries. A multi-stage process is provided, in which cellulose-containing feed material is subjected to one or more pretreatment stages, followed by a dissolution treatment and isolation of cellulose molecules. Isolated cellulose molecules may be used in a variety of downstream applications. Methods and systems for carbonizing precursor fibers to produce carbonized fibers having desired properties and three-dimensional configurations are provided.
