- [Do Silicon Softeners Reduce Sublimation Fastness of Disperse-Dyed Polyester?](https://textileinfohub.com/do-silicon-softeners-reduce-sublimation-fastness-of-disperse-dyed-polyester/): Image credits: wooter.com Short answer: Yes—under certain conditions. Softeners can reduce sublimation fastness of disperse-dyed polyester when they promote Thermomigration or increase surface dye mobility during heat exposure. But with the right dye selection, optimized reduction clearing, and low-migration silicone systems, this risk can be minimized or avoided. Why Problems Occur? When It Does Not Harm! Practical Recommendations for Mills and Process Houses. Why it is essential to know? Softeners are not inherently detrimental to sublimation fastness—chemistry and process control decide the outcome. Mills that pair high-fast dyes with the right finishing systems can achieve soft handle and heat stability—without...
