Sodium 3-nitrobenzenesulphonate is a chemical auxiliary widely used in the textile printing and dyeing industry. Its main function is to prevent dyes from attaching or migrating in non-target areas. The following is a detailed description of the common uses of Sodium 3-nitrobenzenesulphonate:

1. Sodium 3-nitrobenzenesulphonate is used for textile printing and dyeing resistance
Application scenario: In the printing process, the local area of ​​the fabric needs to retain the base color or prevent other colors from invading.
Mechanism of action: Sodium 3-nitrobenzenesulphonate inhibits the reduction reaction of the dye or oxidizes the dye molecules to prevent them from binding with the fiber. For example, in reactive dye printing, it can react with unfixed dyes to make them lose their dyeing ability, thereby avoiding the edge of the pattern from fading.

2. Sodium 3-nitrobenzenesulphonate prevents color bleeding during dyeing
Application scenario: When washing multi-color clothes or dyeing blended fabrics, prevent different colors from penetrating each other.
Actual case: When washing dark and light-colored clothes together, adding Sodium 3-nitrobenzenesulphonate can absorb free dyes and reduce the risk of color cross-linking. Such ingredients are also added to some home dyeing DIY kits.

3. Sodium 3-nitrobenzenesulphonate improves dyeing uniformity
Application scenario: When dyeing large areas of single-color (such as cotton, silk, etc.), avoid the appearance of color spots or streaks.
Mechanism of action: As a retarder, it slows down the dyeing rate and makes the fiber absorb the dye more evenly, especially suitable for fibers that are sensitive to dyeing temperature.

4. Other industrial uses of Sodium 3-nitrobenzenesulphonate
Chemical synthesis: Participates in certain organic synthesis reactions as a mild oxidant.
Electroplating industry: Used as a stabilizer in electroplating solution to prevent premature deposition of metal ions.
Photographic development: Used as an inhibitor in early film development to control the development speed.

Precautions for using Sodium 3-nitrobenzenesulphonate
Safety: Avoid direct contact with the skin or inhalation of dust. It is recommended to wear protective equipment during operation.
Environmental protection: Contains nitro compounds and needs to be treated according to industrial wastewater standards to prevent environmental pollution.
Alternatives: Some environmentally friendly processes have adopted biological enzymes to replace traditional Sodium 3-nitrobenzenesulphonate, but the cost is relatively high.
