Definitions

  • the invention relates to an eco-friendly bleaching activator developed for use in the bleaching of cotton fabrics in the textile industry.
  • the invention particularly relates to a bleaching activator which contains borax, sodium perborate, boric acid, and ozone, to improve the existing properties of the fabric along with the bleaching process and to give new properties to the fabric and its production method.
  • the process to remove the yellowish color of raw cotton products is called bleaching process. Especially if light colors will be used in the fabric to be dyed or printed, bleaching should be applied with precision. Otherwise, not only the desired light colors cannot be obtained, but also bright, vivid colors cannot be achieved in dyeing or printing as well.
  • the bleaching process is indispensable in cotton materials that will be marketed as white, and also this process increases the hydrophilicity of cotton products.
  • bleaching Various methods are available for bleaching, including cold pad-batch method and hot bleaching.
  • cold pad-batch method the bleaching solution is impregnated into the fabric, and it is kept at room temperature for a long period of time, such as 16 to 24 hours.
  • hot bleaching the fabric and the bleaching solution is generally treated at high temperatures for a shorter period of time, such as 30 to 60 minutes.
  • the application relates to a bleaching compound containing benzoyl chloride as an activator along with hydrogen peroxide for use in the textile industry.
  • the application number KR201301 13245 describes an eco/human-friendly cotton fiber bleaching process using an enzyme. In this method, cotton fiber is cleaned and bleached in a bath containing cellulase, stabilizer, sodium carbonate, triacetin, hydrogen peroxide, water, bleaching agent and catalase.
