Application of Novel Chlorine-Resistant Fixing Agent DE-2 on Yarn-Dyed Cotton Fabric

A novel chlorine-resistant fixing agent DE-2 was designed, synthesized, and mixed for application to yarn-dyed cotton fabrics by the pad-dry-cure process. The properties of fabrics treated with DE-2, AR-200, and CF-2 were studied. The results showed that the chlorine fastness of the fabrics treated with DE-2 reached 3.5. The chlorine fastness was better than that of AR-200 and CF-2. Moreover, formaldehyde emissions from the treated fabrics were lower than 75 mg/L. However, formaldehyde emissions from CF-2 treated fabrics were greater than the standard content. Except for color change in a few CF-2 treated fabrics, other fixing agents had no effect on the fabric. Among them, although the DE-2 presented good comprehensive properties, the washing durability was relatively poor.
