Preparation and properties of nano-anionic automobile interior decorative fabrics

The fabric was treated with a self-made anionic finishing agent by pad-dry-cure process.The effects of finishing agent concentration,dipping time,curing temperature and time on the anionic ion concentration released from the fabric were discussed.The optimum finishing technique was obtained: anionic ion finishing agent 30 g/L,dipping time 10 min,curing temperature 160 ℃,and curing time 1 min.The fabric finished by nano-anionic finishing agent could release high concentration of anions,with improved water and oil repellency,having positive significance for the practical application for automobile interior decoration.The anion concentration increased with repeated vibration of the fabric.When the vibration of the fabric reached 900.000 times,the averaged anion concentration released from the fabric is of 5 610 pc/ cm3.This study provided experimental basis for keeping high concentration release of anions from the anionic automobile interior fabric within a long period of time.
