Process Optimization for the Finish of PP Spunbonded Nonwovens with Photo-Catalytic Microcapsule

Abstract:

Microcapsules were prepared using the complex coacervation method with nanoanatase TiO₂ as the core material, gelatin/Arabia gum as the wall material. Then the obtained microcapsules were finished to the PP nonwovens to investigate the photocatalytic properties to the nonwovens. The breaking strength decrease of the finished polypropylene nonwoven after irradiated with the artificial UV lamp was the optimization evaluation index, and the four factors including finishing temperature, adhesive concentration, microcapsule concentration and finishing time were used to design the experimental scheme using the second order orthogonal rotation combination design. The data were processed with SAS software, the obtained optimal finish process is: finishing temperature is 22°C, adhesive concentration is 75g/L, microcapsule concentration is 36g/L, and finishing time 25min.
