Abstract: In order to study further on the anion-generating regulation of anion linen and ramie fabrics,anion finishing agent was used for multi-functional treatment of linen and ramie fabrics by dip-padding technique,and the anion-generating capacity,soaping fastness,surface morphology and molecule structure were tested.The effects of temperature,humidity,fabric species and specification on anion-generating capacity and reasons of better anion-generating capacity of linen and ramie anion fabric were also analyzed.The results reveal that the effects of temperature and humidity on anion-generating capacity are remarkable,and the anion-generating capacity reaches maximum at(30 ℃),RH 80%.In addition,fiber materials, weaves as well as fabric densities also have a definite influence on anion-generating capacity.The molecule structure of the treated fabric is not altered.
