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.

This invention relates to a method for decolorizing a dyed denim fabric through a dry ozone process to obtain an aesthetically pleasing decolorized look or fashionably faded look in the denim fabric. The method comprises three dry ozone treatment processes used alone or in combination thereof. The first dry ozone treatment process includes wetting a denim textile product with water and oxidizing it with ozone. The second dry ozone treatment process includes spraying water to desired areas of the textile product and oxidizing it with ozone. The third dry ozone treatment process includes loading the denim textile product and wetted cotton fabric scraps into a drum, and oxidizing them with ozone.

An ozone cleaning system includes a cabinet defining a cleaning space, and an ozone generator disposed in fluid communication with the cleaning space and configured to produce and introduce ozone therein for cleaning items with ozone. An ozone neutralization unit is attached to the cabinet and includes an inlet and outlet tube each disposed within the cabinet. The ozone neutralization unit includes a heater/blower assembly in fluid communication with each tube and operable for heating and recirculating the ozone within the cleaning space. A method of operating the ozone cleaning system includes receiving an input to commence an ozone cleaning cycle, and then producing and introducing ozone into the cleaning space. The method proceeds by determining if the ozone cleaning cycle is complete, and then initiating and executing an ozone neutralization cycle to accelerate the rate of ozone neutralization after the ozone cleaning cycle is complete.

A method for localized or diffused decolorization of colored fabrics and garments by applying an accelerating substance comprising quaternary ammonium salts and subsequently treating with ozone.

Embodiments relate generally to methods and systems for bleaching textiles using ozone gas that incorporates a color removal step. In one example, there is provided a hybrid machine that incorporates certain features of a washer, but that also includes an integrated blower for gas distribution inside the machine. There is also provided an ozone dosing control system that allows for maintenance of a constant concentration of ozone in the machine. In one embodiment, the ozone output measured in grams/hour at this constant concentration in conjunction with the weight of product measured being treated may be referred to as the bleaching factor. There is further provided a wastewater dye removal step, in which ozone is used to clean the water and remove dyes and other colors that may be deposited via denim or other garments.
