AUXILIARY FOR PRETREATMENT AND DYEING COMBINED PROCESS FOR PES/CO FABRICS
High performance, Cost saving Process
AUXILIARY FOR PRETREATMENT AND DYEING COMBINED PROCESS FOR PES/CO FABRICS
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.
BENEFIT
S OF THE PRODUCTS :
- Saving time
- Saving water ang Energy
- The absorbency of the treated fabric is higher than
the fabric prepared with conventional process - Color shades is more brilliant after Polyester dyeing
- Less pilling.
- Less weight loss
