stain resistance
1.Nanoproducts are showing up in khakis, where they contribute to stain resistance, and cosmetics, where they are used as sunscreens.
2.The SEM analysis shows the nano-size roughness on the plasma treated or chemical surface modified wool scales. Wenzel equation and Cassie and Baxter equation are used to illustrate the relationship between surface roughness and contact angle,then to reveal the reasons why surface modifications are able to impart an improved water repellence and oil repellence and stain resistance to wool.
3.and the resistant criteriaswhich are more important to the volume increment are K￣+ exosmosis capacity,transpirationratio,the permeability constant of leat ground state,the brown stain value of tissue,stomatadiffusion resistance and leat water deficit ratio in turn.
4.Especially for textile printing and dyeing at the special requirements, such as high-Light, humidity rubbing fastness, resistance to chlorine bleaching (reactive), cold heap special dark stain, acid and alkali - resistant requirements of High Temperature Whitener we have corresponding products.
