For large textiles, such as bed sheets, curtains, etc., the amount of sodium chlorite liquid can be increased accordingly.
The dosage of sodium chlorite liquid used in textile bleaching can vary depending on several factors, including the type of fabric, the level of desired bleaching, and the specific process being employed. It is crucial to conduct small-scale trials and tests before implementing the full-scale bleaching process. Additionally, manufacturers may provide recommended dosages based on their specific product formulations and application guidelines. Here are some general considerations for using sodium chlorite liquid in textile bleaching:
Concentration: Sodium chlorite liquid is available in different concentrations, typically ranging from 1% to 5% or higher. The concentration used in textile bleaching may depend on the fabric type and the extent of bleaching required.
Fabric Type: Different fabrics may react differently to sodium chlorite liquid, and the dosage may vary accordingly. Some fabrics are more sensitive to bleaching agents and may require lower dosages to avoid damage or discoloration.
Bleaching Level: The extent of bleaching needed for the textile also affects the dosage. Lighter bleaching may require lower dosages, while more significant bleaching may necessitate higher concentrations.
Testing and Trials: Before full-scale production, conduct small-scale trials on a sample of the fabric to determine the most suitable dosage and bleaching time. This helps to avoid over-bleaching or damaging the fabric during the process.
Process Conditions: The temperature, pH, and other process conditions can influence the effectiveness of the bleaching and, consequently, the dosage needed.
Dilution and Mixing: Diluting the sodium chlorite liquid may be necessary to achieve the desired concentration for specific applications. Proper mixing and agitation during the bleaching process are essential to ensure uniform distribution of the chemical.
Safety Considerations: Always follow safety guidelines and wear appropriate protective equipment when handling sodium chlorite liquid during the bleaching process.
It is essential to note that sodium chlorite is a strong oxidizing agent, and improper handling or dosing can lead to adverse effects on fabrics or even pose safety risks.

4. Application examples
Let's say you have a batch of white sheets that have some yellow stains from prolonged use. The following are example steps for bleaching using sodium chlorite liquid:
Prepare the bleaching solution: pour 500 ml of water into the container, add 25 ml of 5% sodium chlorite liquid, and stir well to obtain the bleaching solution.
Soak the sheets: Place the sheets to be bleached in the bleach solution, making sure to soak completely. Gently agitate by hand to facilitate contact of the stain with the bleach.
Bleaching time: Depending on how stained the sheets are, determine the bleaching time. Under normal circumstances, 5-10 minutes can achieve the desired effect. Be careful not to exceed 15 minutes so as not to damage the fibers.
Rinse the sheets: Take out the bleached sheets, rinse them thoroughly with clean water, and wash away the residual bleach. It can be rinsed repeatedly until the water becomes clear.
Drying and Ironing: Line dry or tumble dry the sheets. Finally, iron the sheet flat to restore its polished look.
Through the above steps, sodium chlorite liquid can effectively bleach the yellow stains on the sheets and restore their original white color.
