Introduction to the STONE WASH in custom clothing
Introduction to the STONE WASH in custom clothing
- STONE WASH is a washing process in the garment factories and china manufacturing clothing industry that utilizes chemical oxidants to destroy the dye structure of fabrics, achieving whitening, fading, or enhancing the vividness of colors. This technique is particularly prevalent in denim products, such as those produced by fashion jeans factories and jorts manufacturers.
- I. Core Objective
- 1.Visual Effects
- (1) Make the clothes present a pure white base color or bright tones, thereby enhancing the color contrast and appealing to apparel companyies and fashion manufacturing companies that prioritize aesthetic appeal.
- (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, catering to the trend-conscious consumers of wholesale clothing vendors and clothing exporters.
- 2.Touch Optimization
- After the chemical treatment, the fiber structure becomes loose, thereby enhancing the softness and skin-friendliness of the fabric, making it an ideal choice for custom clothing makers that focuses on comfort and quality.
II. Process Flow
Pretreatment: This step is typically conducted after general washing or stone washing to guarantee that the fabric surface is devoid of impurities that might hinder the bleaching process. Ensuring a pristine fabric surface is crucial for chinese clothing manufacturing, aiming for high-quality outcomes.
1.Main Processing Stage
(1)Temperature Control: Heat the water to approximately 60°C. Proper temperature regulation is vital for achieving consistent results in custom jeans manufacturing
(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: The reaction time should be adjusted based on the desired fading level, typically ranging from 7 to 10 minutes. Accurate timing is essential in maintaining quality standards for garment factories and fashion jeans factory.
3.Post-treatment: Once bleaching is finalized, sodium thiosulfate should be promptly administered to neutralize leftover chlorine and halt the chemical reaction, thereby safeguarding the fibers from undue harm. This step is fundamental in preserving the integrity of the fabric for outwear manufacturers and ensuring long-lasting durability for clothing brand manufacturers.
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 used for light-colored garments with a high cotton content, enhancing the color lightness without damaging the elastic fibers.
1. Fiber damage: Excessive or unneutralized bleach can easily lead to a
decrease in fabric strength. It is necessary to strictly control the
concentration of the agent and the reaction time.
2. Environmental protection issues: Wastewater from chlorine-containing
bleach needs to be specially treated to prevent environmental pollution.
