T/STSI 82-2026 Silicone emulsion for deepening finishing of textiles

Scope

This standard specifies the technical requirements and test methods for silicone emulsions used in the darkening finishing of textiles, and is applicable to water-based silicone emulsions used for darkening polyester and cotton fabrics. Technically, the product should be a milky white uniform liquid with a solids content of 23.0% to 25.0%, a pH value of 4.5 to 7.0, and good solubility, centrifugation, and acid-base stability. After darkening, the K/S value of the fabric should not be lower than 95% of the standard sample, and the alkylphenol polyoxyethylene ether content should be ≤50mg/kg. The tests should be conducted in accordance with specified national and industry standards. Inspections include factory inspections and type inspections. Products with unqualified safety indicators will be directly declared unfit for use. There are clear requirements for product packaging and storage. The product should be stored at a temperature of 5°C to 35°C, and it should be reinspected if stored for more than six months.
