Provided is an eco-friendly decolorization method of jeans including: a fabric input step of putting denim fabric into a decolorizing device; an ozone gas injecting step of injecting ozone gas into the decolorizing device in which denim fabric is put; and a purified water spraying step of spraying purified water to the denim fabric through a sprayer disposed in the decolorizing device filled with ozone gas through the ozone gas injecting step. The eco-friendly decolorization method of jeans can decolorize naturally and uniformly, and remarkably reduce generation of wastewater by using ozone and water, thereby providing an eco-friendly effect.

A system including: a machine for processing textiles and configured to treat, within the same, textiles with a gaseous mixture including ozone gas; and a dehumidification system connected to, or integrated into, the machine and configured to reduce a humidity of the gaseous mixture. Also, a method for processing textiles, including: in a machine for processing textiles, treating textiles with a gaseous mixture that includes ozone gas; and, using a dehumidification system connected to, or integrated into, the machine for reducing a humidity of the gaseous mixture.

The present invention relates to provision of a textile product having a naturally faded appearance. A damage processing method for a textile product includes: irradiating a surface of the textile product with a laser beam (S1); washing the textile product irradiated with the laser beam with a phosphoric acid aqueous solution (S5); and exposing the washed textile product to ozone gas (S7).

A system and a method for treating a textile material with ozone gas. The system includes: an ozone gas supply system, a hollow chamber fillable with ozone provided by said gas supply system, a textile-feeding port connected to said chamber and comprising a first liquid fillable tank, a textile-discharging port connected to said chamber and comprising a second liquid fillable tank, guide rollers, driving rollers, at least one tension compensator located inside the hollow chamber. The system is adapted for implementing the method, the latter including: using the system and providing liquid to said first and second tanks, providing ozone gas to said hollow chamber, driving the textile material to pass tensed through the system while controlling its tension using the tension compensators. The use of the tension compensators prevents the formation of ozone induced defects on the textile material.

There is provided a process for chemically pretreating reclaimed cellulose fibres to be used in the production of moulded bodies from regenerated cellulose, wherein the pretreatment includes one stage, in which stage acid metal removal and acid oxidative bleaching are carried out together. Advantages include that the propensity of the regenerated cellulose to clog when flowing in a tube and through a nozzle is reduced. This is believed to be an effect of an efficient metal removal. The need for additional bleaching steps and/or metal removing steps is reduced or even eliminated. A one-stage method is more efficient, faster and less costly compared to a multi-stage method according to the prior art. From an environmental perspective, acidic metal removal is preferred over removal by chelating agents such as EDTA.

The present invention discloses means, and systems utilizable in a method for converting post-consumer cellulose-containing (e.g., cotton) textile waste (ctPCR) to nanocellulose, derivatives, and products thereof, comprising steps as follows: grinding said ctPCT; suspending the ground ctPCR in basic pH hydrophilic slurry; and exposing the same to ozone gas.
