Abstract: Having carried out the anion coating finish of the fabric and standardization of anion-testing method,the effects of category and particle size of tourmaline,fiber category,temperature and humidity on anion-generating capacity are analyzed to illustrate the relationships between anion-generating capacity and the above factors.The results reveal that anion-generating capacity of anion linen fabric coated by schorl is superior to that by elbaite or dravite;finer the particle size,greater the anion-generating capacity.In the case of the result of the treatment,linen anion fabric is the better,followed by in this order: linen/cotton(fabric>)cotton fabric>linen/viscose fabric.Anion generating amount increases non-linearly with temperature rising and tends to saturation and increases approximate linearly with humidity increase.
