Washable hydrophilic deepening silicone oil as well as preparation method and finishing agent thereof

The invention discloses washable hydrophilic deepening silicone oil and a preparation method thereof, the washable hydrophilic deepening silicone oil comprises a chain segment as shown in a structural formula I, wherein m is greater than or equal to 3 and less than or equal to 20; r2 = n > = 5; pO is propylene oxide, EO is ethylene oxide, c is more than or equal to 6 and less than or equal to 8, and d is more than or equal to 2 and less than or equal to 5; pO is propylene oxide, EO is ethylene oxide, 30 > = a > = 5, and 20 > = b > = 6. The invention also provides a finishing agent. As a finishing agent, the washable hydrophilic deepening silicone oil can improve the depth of textile cloth, reduce the use amount of reactive dye and save enterprise cost, and after the textile cloth is subjected to after-finishing through the silicone oil finishing agent, the hydrophilicity and washing resistance of the textile cloth are both excellent. 本发明公开了一种耐洗亲水增深硅油及其制备方法，该耐洗亲水增深硅油包括结构式I所示链段：其中，20≥m≥3；R2＝n≥5；PO为环氧丙烷，EO为环氧乙烷，
