The invention discloses a kind of dyeing and finishing technologies of polyester-cotton blend mixed fiber fabric, include the following steps：S1, pre-treatment successively carry out polyester-cotton blend mixed fiber fabric boiling drift, enzyme washes processing；S2, mercerising sizing, will carry out pre-setting after fabric at room temperature alkali immerging；S3, dyeing immerse fabric in the dye liquor that disperse dyes are formed, and 30-40 DEG C enters dye, are warming up to 90-110 DEG C with the heating rate of 0.8-1 DEG C/min, warm water washing, hot-air seasoning after infrared preliminary drying；The suspended substance dye liquor for padding reducing dye formation again at room temperature pads reducing solution, and decatize reduction, oxidation, warm water washing is soaped, then washes drying；S4, final finishing will successively carry out soft, flame-proof treatment.The dyeing and finishing technology of polyester-cotton blend mixed fiber fabric of the present invention not only significantly improves the performances such as feel, the elasticity of fabric, but also even dyeing, and color fastness is high, and it is plentiful to go back color. |
