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 decolorization method of a polyester fabric includes: providing a polyester fabric, in which the polyester fabric is a dyed polyester fabric and the polyester fabric is adhered with a dye and has a first L value; providing a first decolorizing solution and a second decolorizing solution, in which the first decolorizing solution contains a reductant and the second decolorizing solution contains an oxidant; and performing a decolorization process which includes: using one of the first decolorizing solution and the second decolorizing solution to decolorize one portion of the dye and using another one of the first decolorizing solution and the second decolorizing solution to decolorize another portion of the dye, so that a color of the dye is removed and the polyester fabric is white in color and has a second L value that is greater than the first L value.

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).

Laser finishing of apparel products allows an operating model that reduces finishing cost, lowers carrying costs, increases productivity, shortens time to market, be more reactive to trends, reduce product constraints, reduces lost sales and dilution, and more. Improved aspects include design, development, planning, merchandising, selling, making, and delivering. The model uses fabric templates, each of which can be used to produce a multitude of laser finishes. Operational efficiency is improved.

Methods for processing denim are provided. An initial fabric is abraded by passing the initial fabric through an abrader at a first predetermined speed, thereby obtaining a pre-washed fabric with an abraded texture. The abrader comprises one or more sanding boards, where each respective sanding board has a respective diamond surface that contacts the initial fabric while spinning about a respective axis at the respective center of the respective sanding board during the abrading. The pre-washed fabric is then washed with an ozone composition, thereby obtaining an ozone washed fabric.
