  • In order to promote an efficiency CPB process, we developed microwave system in CPB process. The whiteness and penetration ability of microwave-CPB pre-treated fabrics were superior to CPB only. This results indicates that microwave-CPB pre-treatment promotes CPB efficiency in agent usages and batching time.

  • A solution containing 3-Mercaptopropyltr-imethoxysilane(MPTMS) was employed to modify surface of cotton fabrics with a silver colloid. Silver nanoparticles were applied on cotton fabrics via treatment with 3-MPTMS. The rate of silver nanoparticles on the fabric surface were measured with Energy Dispersive Spectroscopy(EDS). EDS results confirm the silver atom on the cotton surface.
