Key developments in cold pad batch technology were started in 1957 and is still ongoing: - Development of dosing pumps (Hoechst) - Introduction of sodium silicate as a fixing alkali (Hoechst) - Development of microwave and oven lab fixation method (Hoechst) - Mathematical determination of pad liquor stability under practical conditions (Hoechst) --- Optidye CR (DyStar) - Development of silicate free alkali systems (DyStar)
All Levafix CA dyes show extremely high colour build-up and highest robustness in production. Ternary combinations based on the above demonstrate good lab to bulk transferability and bulk to bulk repeatability, highest fastness performance and excellent face-back uniformity. Production trials have to be made to test the lab to bulk transferability but also to be aware of material differences due to emerising. The bulk processing conditions have to be imitated in the lab. There has to be a correlation between the different process conditions.
Conclusion The expertise involved in Controlled Pad Batch technology provides the basis for better quality, higher productivity, higher differentiation and reduced production risk. The cpb process continues to develop further improvements for optimising diffusion and reproducibility through both dye innovation, application and parameter control.
This can only be achievable by close co-operation between global retailer, innovative dyestuff producer and leading machinery manufacturer to develop optimised solutions for new fastness performance requirements to meet increased customer expectations on the latest fabric developments whilst minimising non-conformance material.
German textile solutions provider DyStar offers optimised dye selection and application technology to meet the highest performance requirements. As a partner for the whole textile chain DyStar provides Color Confidence to fulfil all requirements of the world's leading retailers and Controlled Coloration to offer textile mills cost-effective dyes and right first time technology for any requirement.
