Effect of Carrier on the Structure and Performance of Polyphenylene Sulfide Fiber

Abstract:

Polyphenylene sulfide (PPS) is considered as a high performance thermoplastic material and to be used in many areas, but the application of PPS used as protective clothing is limited because it is difficulties to be dyed and finished. In this work the effects of benzyl benzoate as a carrier on the structure and performance of PPS especially dyeability were evaluated. The glass transition temperature, crystalline structure and orientation degree of treated PPS fiber with benzyl benzoate were investigated by differential scanning calorimetry (DSC), X-ray diffraction analysis and velocity-oriented tester. Adsorption thermodynamic and kinetic study of disperse dye on PPS treated with carrier was carried out under the condition of pH value 5, initial dye concentration 0.01–0.5 g/L and liquor ratio 1,000:1. The results indicated that benzyl benzoate, as a dyeing carrier, could reduce the glass transition temperature and orientation degree of treated PPS fiber. The benzyl benzoate could improve the standard affinity, diffusion coefficient and the equilibrium dyeing rate of disperse dye on PPS fiber, while the decrease of tensile strength was very little.
