BLEACH WASH and custom clothing

BLEACH WASH and custom clothing

    Rinsing, specifically BLEACH WASH, is a prominent washing process in the ‌garment factory‌ and ‌apparel company‌ industries. It utilizes chemical oxidants to break down the dye structure of fabrics, achieving whitening, fading, or enhancing the vividness of colors. This technique is particularly prevalent in ‌denim products‌ and ‌mens clothing manufacturers‌.

I. Core Objective

Visual effects

(1) Make the clothes present a pure white base color or bright tones to enhance the color contrast;

(2) When combined with stone washing (such as "stone rinsing"), it can create a retro style where gray and white tones coexist with wear and tear,  popular among ‌fashion manufacturing companies‌ and ‌fashion clothes supplier‌s.

2. Touch optimization: After chemical treatment, the fiber structure becomes loose, enhancing the softness and skin-friendliness of the fabric.

II. Process Flow 

1‌.Pretreatment‌:This step is typically conducted following general washing or stone washing to guarantee the absence of any impurities on the fabric surface that could hinder the bleaching effect, ensuring high quality for ‌wholesale clothing suppliers‌ and ‌garment factories‌.

2‌.Main Processing Stage‌

(1) ‌Temperature Control‌: Heat the water to approximately 60°C, crucial for the ‌fashion manufacturing‌ process.

(2) Bleach selection:

① CHLORINE BLEACH: Sodium hypochlorite (NaClO) is used to quickly destroy indigo dye. The fading effect is rough and intense, and it is mostly used for dark denim.

② OXYGEN BLEACH: Hydrogen peroxide (H₂O₂) is used. The effect is relatively mild. After fading, the fabric surface may slightly turn red. It is suitable for light-colored fabrics or those that require a natural gradient effect.

(3) ‌Time Control‌: Adjust the reaction duration based on the desired fading level, typically ranging from 7 to 10 minutes, crucial for achieving consistent results in ‌fashion jeans factories‌.

‌3.Post-treatment‌:Upon completion of bleaching, sodium thiosulfate should be promptly used to neutralize residual chlorine and halt the chemical reaction, safeguarding fibers from undue damage, ensuring long-lasting quality for ‌custom mens jeans‌ and other ‌clothing brand manufacturers‌' products.

III. Application Scenarios

1. Denim products: Indigo dye is quickly stripped off through chlorine bleach to form the signature "snow pattern" or high-contrast color drop.

2. Blended fabrics: Oxygen bleaching is utilized for light-colored garments with a high cotton content, enhancing the color lightness without damaging the elastic fibers. This process is highly valued by fashion manufacturing companies specializing in personalised sports clothing.

IV. Process Risks

1. Fiber damage: Excessive or unneutralized bleach can easily lead to a decrease in fabric strength, affecting the durability of wholesale clothing vendors and custom clothing maker products. It is necessary to strictly control the concentration of the agent and the reaction time.

2. Environmental protection issues: Wastewater from chlorine-containing bleach poses significant environmental concerns. Special treatment is required to prevent pollution, aligning with the sustainable practices of china manufacturing clothing and responsible clothing exporters.
