降低產品整個生命周期中的C的排放，實現節能減排，降低能耗一一傳統滌綸染色需要高溫高壓條件下才能進行，而陽離子改性常溫常壓條件下即可上色。 Molecular chemical bond, better fastness. Can effectively solve the problems color block after washing the stick color, high temperature composite fabric fastness during the process of garment making. Coloring principle can achieve diversification, color, jacquard fabric, gray and other effects. Reduce the C emissions during whole life cycle of product, the traditional polyester dyeing can be carried out under high pressure and high temperature conditions, while the cationic modification at normal temperature and pressure condition while be ok. 陽離子改性滌綸可以用陽離子燃料染色是因為纖維在紡絲過程中加入了可染色的第三單體的緣故。這個第三單體就是磺酸基。 而普通滌綸中是沒有磺酸基的，這就是陽離子滌綸可以用陽離子和分散燃料染色的原因。 Cationic modified polyester can dyeing with cationic dyes is because the adding of third monomer during fiber spinning process, The third monomer is sulfo radical. While the ordinary polyester doesn't have sulfonic acid, This is the reason why cationic polyester can use cationic dyeing with disperse dyes.
