GB/T 36971-2018 in English

This standard outlines methods for evaluating the migration of dyes from fabrics to polyvinyl chloride coatings under specific conditions. It provides detailed procedures for conducting tests that assess the resistance of dyes used in textile products to migration when in contact with polyvinyl chloride materials. The procedures described include the preparation of test samples, the application of appropriate testing conditions, and the determination of migration levels through visual and instrumental evaluation techniques. The standard is intended to be used by manufacturers, testing laboratories, and other stakeholders involved in the production and quality control of textile products that may come into contact with polyvinyl chloride coatings. It supports the development of products that meet safety and performance requirements in various applications. The content is structured to ensure consistency and reliability in test results, facilitating comparisons between different materials and products.
