摘　　要：涤棉(T/C)工装面料一般使用分散/活性染料或者分散/还原染料染色,染色后的下机布pH值一般在9~10左右,需要充分水洗至pH值接近中性才能使工装面料的后续各种功能整理顺利进行。为此,研制了一种无磷环保型pH值调节剂,具有良好的碱中和能力和缓冲性能,能有效控制下机布的布面pH值,保证功能性工装面料的成品质量的同时,缩短水洗工艺流程,减少印染废水的排放和降低水电气能耗。同时对敏感色、鲜艳色的色光影响小,有利于产品质量控制。Polyester/cotton(T/C)uniform fabrics were usually dyed with disperse/reactive dyes or disperse/vat dyes.After dyeing,the pH value of the fabric was generally about 9~10,and it need to be fully washed until the pH value was close to neutral,so that the subsequent functional finishing of the uniform fabric could proceed smoothly.Therefore,a phosphorus free environmental pH regulator was developed,which had good alkali neutralization ability and buffering performance.It could effectively control the pH value of the fabric surface,ensure the finished product quality of functional uniform fabric,shorten the washing process,reduce the discharge of printing and dyeing wastewater and reduce the energy consumption of water and electricity.At the same time,it had little influence on the color of sensitive and bright color fabric,which was conducive to product quality control.
