Alternative Hydrophobic Treatments Applied on Dyed Fabrics

Abstract:

The product 3-chloro-2-hydroxypropyl stearate (CHPS) was used for durable hydrophobic finishing of cotton fabrics dyed with Reactive Blue 19, Vat Blue 4 and Direct Red 95. The hydrophobization compound used in this study was easy to synthesize, inexpensive and effective. The presence of CHPS on hydrophobic treated cellulose fiber was put into evidence by FTIR analysis. The hydrophobicity of treated sample was proved by water contact angles values and absorption times of the water drops. The best water water contact angle (150 degrees) and the best absorption time of water drop (180 min) were obtained for the samples treated with 60g/L CHPS. The effects of CHPS on chromatic parameters, colour fastness of dyed samples and comfort index (air permeability, hygroscopicity, rigidity) were evaluated. Keywords: Hydrophobization, water contact angle, chromatic parameters, colour fastness, dyed cotton fabric
