After milling, the appearance of the fabric is improved, the hand feels fuller and softer, and it is warmer and more elastic. Sweater milling method: Detergent milling method: The sweater can be placed in a drum-type washing machine or a tumbler-type milling machine. The process flow is as follows:
Preform → soaking → cashing → washing → dehydration → drying
Knitted knitted sweaters of bright colors need to be bleached before dyeing to avoid affecting the shade and brightness. Generally, oxidation bleaching can be used first, and then reduction and fluorescent whitening processes are used. The process flow is as follows:
Clothes blanks → decontamination → hydrogen peroxide bleaching → reduction bleaching → fluorescent whitening → cleaning → dehydration → finishing and styling
