1. Reasons for the decrease in heat transfer fastness
In the textile industry, we often encounter some tricky problems, and the decrease in heat transfer fastness is one of them. Due to the catalytic effect of light, oxygen in the air reacts with dispersed dyes in fabrics, causing yellowing and color change in polyester fibers and additives; Alternatively, dispersed dyes may sublimate and become lighter under the action of heat, which is known as a decrease in sublimation fastness, and these situations are collectively referred to as a decrease in heat transfer fastness. And the emergence of this phenomenon is actually caused by the widespread use of amino silicone oil microemulsion softeners containing a large amount of non-ionic surfactants in textiles in the past 20 years.
2. Ways to solve the problem of decreased heat transfer fastness
We are not helpless in the face of this difficult problem. The key to solving this problem lies in using a special heat sublimation fastness enhancer, namely polyester fixing agent. Using it before setting can effectively prevent the sublimation fastness of dispersed dyes from decreasing during setting. This polyester fixing agent performs well in handling dispersed dyes, not only significantly improving sublimation fastness, but also effectively enhancing washing fastness
3. Advantages of Polyester Fixing Agent
It is worth mentioning that polyester fixing agents have minimal impact on fabric color, which means that while solving the problem of fastness, they can maintain the original color and quality of the fabric to the greatest extent possible.
In short, although the problem of decreased heat transfer fastness has brought certain difficulties to the textile industry, we can effectively solve this problem and improve the quality and stability of textiles by using polyester fixing agents.
4. Application methods
