Method of recycling a textile material which comprises cellulose for manufacturing regenerated cellulosic molded bodies, wherein in the method the textile material is comminuted, at least a part of non-fiber-constituents of the comminuted textile material is separated from fiber-constituents of the comminuted textile material, at least a part of non-cellulosic fibers of the fiber-constituents is mechanically separated from cellulosic fibers of the fiber-constituents, at least a further part of the non-cellulosic fibers is chemically separated from the cellulosic fibers, and the molded bodies are generated based on the cellulosic fibers after mechanically separating and chemically separating.

A method of producing a chemical pulp from a textile material which comprises cellulose for manufacturing regenerated cellulosic molded bodies, wherein in the method the textile material is comminuted, at least a part of non-fiber-constituents of the comminuted textile material is separated from fiber-constituents of the comminuted textile material, at least a part of non-cellulosic fibers of the fiber-constituents is mechanically separated from cellulosic fibers of the fiber-constituents, at least a further part of the non-cellulosic fibers is chemically separated from the cellulosic fibers, and producing regenerated molded bodies from the chemical pulp based on the cellulosic fibers after mechanically separating and chemically separating.

A method for manufacturing fabric with flat screen and digital printed patterns includes: singeing, pretreatment, flat screen scraping sizing, drying, pattern printing, humidification, steaming treatment, washing, and non-ironing and soft setting. The pretreatment is a biological enzyme pretreatment process including: cloth feeding at 75° C., dipping, scouring and bleaching in a working fluid, heating to 90° C. for treatment of 30 minutes, draining, hot water washing and cold water washing. A shortened process flow can be realized, and the positioned sizing that uses a flat screen to scrape a sizing agent to a pattern position to be digital spray-printed on instead of traditional full-width sizing for sizing and printing, which greatly reduces the amount of sizing agent used, lowers production cost and reduces waste water pollution, and solves problem that the fabric is mottled caused by the application of sizing agent in areas without printed pattern due to full-width sizing.

A mist of water and air and ozone gas is used in the finishing of fabrics of jeans and other apparel to achieve a faded, worn, or washed appearance and finish. Jeans or other apparel items are processed in a chamber of a finishing machine. Water and air mist that includes drops of liquid water are sprayed into the chamber. Ozone is separately introduced into the chamber. After processing, the jeans or other apparel will have a stonewashed or acid-washed appearance.

Disclosed are methods and apparatus for cleaning a substrate, such as a fabric material, involving the application of optical energy to the substrate, typically in the form of a beam of light, where the energy of the beam causes removal of the contaminant from substrate, such as from the fibres of a fabric material. The cleaning may occur via any mechanism, including one or more of, alone or in any combination, ablation, melting, heating or reaction with the substrate or contaminant or agent introduced to aid in the cleaning. The optical energy is typically applied to a selected area of the substrate (e.g., as a beam), and the substrate and beam or optical energy source moved relative to one another so as to clean a larger area of the substrate, either by moving the substrate or the beam, or both. Movement of the beam with respect to the substrate can be attained through a beam scanning mechanism or through movement of the optical source itself.

A whitening composition for fabric, in particular, unbleached cellulosic fiber-containing fabric. The composition includes a blue dye, a violet dye; and, optionally, a thickening agent; wherein the composition is free of bleaching agents and optical brighteners. A method of whitening a fabric using whitening compositions is also disclosed.
