AUXILIARY FOR COMBINED PROCESS OF PE BLENDS

16/11/2017

AVCO-COMBIBLEACH is a unique auxiliaries which allows us to perform a combined process of polyester dyeing and pretreatment for T/C or other PES blended fabrics by exhaustion. It is a synergictic compound  designed to obtain the highly dispersing and levelling properties as well as good detergency effect.

 BENEFITS OF THE PRODUCTS :

  1. Saving time
  2. Saving water ang Energy
  3. The absorbency of the treated fabric is higher than the fabric prepared with conventional process
  4. Color shades is more brilliant after Polyester dyeing
  5. Less pilling.
  6. Less weight loss
