RETARDER-ACR |

Acrylic Retarding Agent

Retardar ACR is a retarding agent for dyeing of acrylic and its blends  (fibre, yarn, fabric, garment with cationic dyes). It has high affinity for acrylic fibres. It regulates the strike rate of cationic dyes by competing with dyes for active groups in the fibre. The product is used for leveling of faulty dyeings on acrylics. Acrylic fibres can be dyed by either batch or by continuous process.

Application

Retarder-ACR* 0.6-1.2% 
is recommended as a retarder in acrylic dyeing. Concentration of Retarder-ACR is inversely proportional to the depth of shade. For fibres with a higher rate of dyeing, a higher concentration of retarder-ACR is recommended.

*Dosage of Retarder-ACR is based on the concentrated product's strength.

Dosages of diluted product to be calculated on the basis of solid content.

Instructions For Dilution 

Procedure to prepare 25% diluted product of 80% Retarder-ACR
