Cotfix HE dyes are basically bis monochlorotriazine reactive dyes with low reactivity and high substantivity. These dyes are characterized by high but slow exhaustion and high fixation values. Washing off of dyed goods is easier due to higher fixation.
Due to the high fixation (85% and more) pollution problems are also minimized since the drained liquor contains minimal of unfixed dyes.
Characteristics of Cotfix HE dyes:
• Better reproducibility and hence batch to batch variation is minimized.
• High tinctorial value due to excellent build up properties
• Eco friendly due to higher fixation values.
• Better fastness properties.
• Wide range of application since it is suitable for all types of cellulosic materials like yarn, fiber, piece dyeing and garments.
Cotfix HE dyes are most suitable for garment dyeing, because of their high exhaustion and fixation properties at higher temperature (80°C) that facilitate uniform and level dyeing of stitched garments on all its parts like collar, scuffs and stitched yarn. Moreover because these dyes posses outstanding fastness characters when compared to other class of reactive dyes.
These dyes are most suitable for exhaust dyeing and in particular in that machinery where you can easily achieve and maintain the 80°C on the fabric.
