Indigo-dyed garments are treated with an anti-ozone agent to prevent ozone-related degradation of the garments before laser finishing. Without treatment, the garments can exhibit color loss (e.g., color change or fading) from exposure to ozone in the atmosphere. The indigo-dyed garments with anti-ozone treatment can serve as base templates in a laser finishing process flow. The anti-ozone treatment of the base templates can include a rinse including an ascorbic acid or vitamin C constituent during a base preparation process. Then quantities of these base templates can manufactured and stored for periods of time without exhibiting ozone-related degradation effects.

A method for decolorizing a polyester fabric is provided, which includes: providing a dyed polyester fabric, in which a material of the dyed polyester fabric contains a dye and a water repellent; providing a composite solvent, in which the composite solvent includes propylene glycol methyl ether (PM) and acetic acid that are mixed together; and performing an extraction process, which includes using the composite solvent to wet the dyed polyester fabric and remove the dye and the water repellent from the material of the polyester fabric by extraction, so as to obtain a reduced polyester fabric.

A method for recycling a polyester fabric is provided. The method includes providing a polyester fabric that is dyed and has dye and water repellent attached thereon, providing a composite solvent containing water and acetic acid mixed with each other, performing an extraction operation including infiltrating the polyester fabric with the composite solvent and extracting the dye and the water repellent, and carrying out a liquid state polycondensation reaction on the polyester fabric so that an intrinsic viscosity of the polyester fabric is increased and residual impurities of the polyester fabric are further removed.

A method for producing recycled polyester chips from a recycled polyester fabric is provided. The method includes: providing the recycled polyester fabric attached with dyes and/or coating glue; performing a color removal process to at least partially remove the dyes and/or the coating glue attached to the polyester fabric; performing a de-polymerization process which includes: using a chemical de-polymerization liquid to chemically depolymerize the recycled polyester fabric, so as to form a de-polymerization product containing bis(2-hydroxyethyl) terephthalate (BHET) and oligomers; performing a purification process, so as to enhance a purity of the BHET in the de-polymerization product; and performing a granulation process, so as to re-polymerize the purified BHET and form the recycled polyester chips (r-PET).

The present disclosure provides a method for processing an all-polyester fiber cotton-like fabric with sunlight resistance. The method includes: 1) weaving a PTT/PET bicomponent composite stretch yarn into a fabric; 2) dyeing processing the fabric; and 3) finalizing and finishing, wherein the finalizing and finishing comprises: a) preparing a finishing liquor obtained by mixing a crosslinking agent and an emulsion of benzophenone-containing polyorganosiloxane; b) padding the fabric; and c) drying and finalizing at a high temperature.

Provided is an enzymatic treatment on polyester/cellulose blend textile by contacting the textile with a cutinase and preferable with cellulose as well.
