摘要: Cotton-containing textiles, such as “trash” feedstock in terms of end-of-life-cotton textiles, may be used to produce sugar without the same kinds of harsh pretreatments used for other biomasses, such as corn, grass sources, or wood. Disclosed is a process for production of sugar from a cotton-containing textile waste fabric comprising optionally mechanically pretreating the cotton-containing textile, pretreating the cotton-containing textile with an acid pretreatment to form a slurry, cooling the slurry, adding at least one base to the slurry, adding at least one additional acid to the slurry to form a buffer in situ, adding a hydrolysis enzyme, and optionally filtering the slurry.

摘要: A liquid fabric treatment composition including a hydrocarbon wax, a crosslinking agent, and a polyester warp sizing agent. The liquid fabric treatment composition may include a disperse dye. Methods of using these compositions for dyeing cellulose-containing fabric with a disperse dye include contacting a fabric containing cellulose with a liquid fabric treatment composition to yield a pretreated fabric, and heating the pretreated fabric to yield a treated fabric. The treated fabric contains a urethane compound formed by a reaction of the hydrocarbon wax, the crosslinking agent, and the cellulose of the fabric.
