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.

The present invention refer to a process for the production of microbial cellulose using a waste textile material, for example 100% cotton or blended cotton/polyester/elastane waste textile, said waste textile material comprising cellulose, comprising the following steps: providing an amount of said waste textile material; pre-treating said waste textile material with an aqueous solution comprising NaOH and urea, to obtain a pre-treated fabric, wherein said step of treating said waste textile with an aqueous solution comprising NaOH and urea is carried out at a temperature ranging from 25 C. to +30 C.; treating said pre-treated fabric with cellulase enzymes, to convert said cellulose into glucose, whereby a mixture including glucose is obtained; preparing a culture medium comprising said mixture including glucose; inoculating said culture medium with microbial cellulose producing microorganisms; and incubating said microbial cellulose producing microorganisms to obtain microbial cellulose.

An article is comprised of a composite substrate comprising a non-polar thermoplastic polymer such as a polyolefin or polyvinyl chloride and a filler having polar groups, the composite having a dye sublimation image in a layer adhered or integral to a surface of the composite. The article may be made by exposing the aforementioned composite substrate to a temperature above 100? C., which is typically above the melt temperature of the non-polar thermoplastic polymer, to about 250? C. and pressing a dye sublimation film onto the composite substrate for a time to imprint the dye sublimation image into the accepting layer forming the article. The article may be used for applications having aesthetic or structural requirements in the construction arts such as railing, decking or fencing.

The present invention relates to a process for manufacturing a composite article comprising cellulose pulp fibers and a thermoplastic matrix, wherein said process comprises the steps of: a) mixing a refined aqueous pulp suspension with a water suspension of thermoplastic fibers into a composition, b) forming the composition into a fiber web, c) dewatering the fiber web, d) drying the fiber web, and e) heating and pressing the dried fiber web from step d) to melt said thermoplastic fibers into a thermoplastic matrix and form a composite article.

What is shown is a method for the recovery of raw materials from blended textile wastes, which includes the following steps in the given order: a) providing blended textile waste that includes at least a cellulose component and at least a polyester component, b) treating the blended textile waste in an aqueous treatment solution in order to depolymerize the polyester component and dissolve it in the treatment solution, c) separating the cellulose component from the treatment solution and recovering a cellulose raw material, d) filtering the treatment solution in order to remove foreign substances, particularly dyes and metal ions, from the treatment solution, and e) precipitating terephthalic acid from the treatment solution, separating the precipitated terephthalic acid, and recovering a terephthalic-acid-including polyester raw material. In order to, within the scope of the mentioned method, enable the recovery of raw materials with an increased level of purity, it is proposed that filtering the treatment solution in step d) should at least comprise a filtration by an adsorbent filter medium.

The present disclosure is directed toward an extrusion process for making a poly alpha-1,3-glucan ester film. These films can be translucent and used in packaging applications.

Described is a base material for dry-peelable wallpaper, having greater dimensional stability and improved printability. The problem is solved by a composite fiber web consisting of a voluminous first layer of fiber material, a thermoplastic polymer film, and a second, less voluminous layer of fiber material.

The present invention achieves a phase difference film that is excellent in wavelength dispersion property, in-plane retardation, and film thickness, by using a polymeric material (i) which is composed of at least one type of cellulose derivative having a specific alkoxyl group substitution degree D.sub.1 and a specific 2-naphthoyl group substitution degree D.sub.2 and (ii) which has a specific total 2-naphthoyl group substitution degree D.sub.3.

A filter cartridge includes a radio frequency identification, RFID, tag positioned on a casing. A compressed cellulose foam is positioned over the RFID tag on the casing. An impermeable material is positioned over the cellulose foam on the casing at an outer surface of the casing. The impermeable material defines a passage that extends through the impermeable material to the cellulose team. The passage is configured such that water is flowable through the passage to the cellulose foam. The compressed cellulose foam is configured for wicking the water from the passage to the RFID tag.

A reinforced polymer composite includes a polymer matrix and a strengthening agent. The strengthening agent includes highly crystalline cellulose nanocrystals (CNC) and a stabilizing agent. The crystalline cellulose nanocrystals (CNC) have dimensions of about 3 to 5 nm in width and about 100 to 300 nm in length and a density of about 1.6 g/cm.sup.3 and the stabilizing agent may be one of Boehmite nanoclay (Boe) and Cetyltrimethylammonium Bromide (CTAB) or a combination of both.
