Embodiment 1

[0045] Example 1: Stone washed denim (denim)

[0046] Materials and methods : Table 3 contains the materials used throughout the experimental period.

[0047] Table 3. Materials used

[0048]

[0049] Processing of denim garments (5 garment samples, 700g each) with a laser device (mode 01hs, resolution: 150.000dpi on X-axis, 9.000dpi on Y-axis) to simulate visual effects such as scratches on denim ( strike) and lines (line). To stonewash using foam and cellulase, the garment is treated in a washing machine with an aqueous solution containing: ATB 710 (a liquid cellulase preparation capable of sanding at room temperature) 30 g / L; Fortres GSL (based on Dispersant for ionic surfactants, primarily added to limit back staining) 10 g / L; Anhydrous Citric Acid (to achieve pH 6.0) 0.4 g / L; and Foaming Agent #1 18 g / L. Foamer #1 was prepared according to the examples shown in Table 2.

[0050] The composition is prepared and 700 grams of foam (per kilogram of garment) is inject...

Embodiment 2

[0054] Example 2: Bleaching of stonewashed denim using NaOCl and foam

[0055] Materials and methods : Table 5 contains the materials used throughout the experimental period.

[0056] Table 5. Materials used

[0057]

[0058] Processing of denim garments (5 garment samples, 700g each) with laser equipment (mode 01hs, resolution: 150.000dpi on X-axis, 9.000dpi on Y-axis) to simulate visual effects such as scratches on denim and line. Garments were then treated with foam and liquid cellulase as in Example 1. Then, dehydration was carried out by a centrifuge so as to retain 550 grams of water per kilogram of garment (55% dehydration rate). Garments were then bleached using a foam and NaOCl treatment; garments were treated using the same washing machine as above using an aqueous solution containing sodium hypochlorite (NaOCl); 200 g / L; and frother #2 (80 g / L). Foamer #2 was prepared according to the examples shown in Table 2.

[0059] The composition was prepared and 120...

Embodiment 3

[0063] Example 3: Using Avol Evanix and Foam Bleach

[0064] Materials and methods : Table 7 contains the materials used throughout the experimental period.

[0065] Table 7. Materials used

[0066]

[0067] Processing of denim garments (5 garment samples, 700g each) with laser equipment (mode 01hs, resolution: 150.000dpi on X-axis, 9.000dpi on Y-axis) to simulate visual effects such as scratches on denim and line. The garment is then bleached with foam and Avol Evanix by the garment treatment method in a washing machine using an aqueous solution comprising: Avol Evanix, which is a sodium persulfate activator produced by Kemin Textiles s.r.l., 520 g / L; synergist OW (active substance: Sodium Persulfate) 86 g / L; and Foaming Agent #1 (24 g / L).

[0068] The composition was prepared and 700 grams of the composition (per kilogram of garment) was injected into the washing machine within 5 minutes of starting garment treatment. Do a 15-minute suds bleach cycle in the washing ...

Abstract

The present invention offers a new approach to the treatment of garments, including novel compositions and related methods using foam as a carrier of chemical products that are used during the industrial treatment of textiles. Another aspect of the invention relates to methods for reducing total water content necessary in industrial treatment of garments. Another aspect of the present invention relates to processes and methods of forming a foam that can be used for textile treatment.

Description

[0001] References to related applications [0002] This application claims priority to U.S. Provisional Patent Application 62 / 884,543, entitled "Method of Treating Textiles Using Foam and Related Methods," filed August 8, 2019, the entire disclosure of which is incorporated by reference in its entirety Incorporated into this article. Background technique [0003] Industrial textile processing for garments is usually done using large washing machines that add garments and water. Chemicals are added for various treatments including but not limited to desizing (removal of sizing starch), stone washing (enzymatic), scrubbing, cleaning and finishing (finishing). In most cases, large volumes of water are required for disposal. Typically, the chemical is dissolved and mixed into a vehicle, usually water, to adequately disperse the material produced during the process (for example, a dispersion of indigo dye released in water during a stonewashing process) and to facilitate the inte...
