摘　　要：采用分散染料热升华型墨水直接对涤纶织物进行了喷墨印花,墨水在织物上容易渗化、得色深度低、日晒牢度差.比较采用不同质量分数的自制预处理剂(具有多官能团的非离子型活性高分子物质,简称A)对涤纶织物进行预处理,然后喷墨印花.结果表明:预处理剂w(A)=1%,经处理后的涤纶织物颜色鲜艳,K/S值有所提高;当用量为2%时,涤纶织物喷墨印花发生的渗化现象明显减弱;耐摩擦牢度和耐晒牢度均未发生明显变化,均能达到应用要求.Polyester fabric was inkjet printed with disperse dye thermal sublimation ink.The ink was easy to bleed,had poor color yield and poor light fastness.Pretreatment of polyester fabric with different mass fractions self-made pretreatment agent,nonionic reactive polymer with multi-functional groups（A）,were compared,afterwards inkjet printing was carried out.The results showed that the color of polyester fabric was brilliant,and K/S value was increased when w（A） was 1% of pretreatment agent was used.When the dosage of pretreatment agent was 2%,the bleeding of inkjet printed polyester fabric was distinctly decreased,and crocking fastness and light fastness was unchanged,which could meet the demand.
