The invention belongs to the technical field of textile printing and dyeing, and particularly relates to a cotton fabric ozone pretreatment assistant system and process, the cotton fabric ozone pretreatment assistant system comprises a reagent A and a reagent B. The reagent A is a cold pad batch assistant, and the formula comprises a refining agent DM1346F, hydrogen peroxide, a low-temperature bleaching activator, NaOH and water; and the reagent B is a working solution and comprises a cellulose protective agent, a penetrant and water. Based on the cotton fabric ozone pretreatment auxiliary agent system provided by the invention, the invention further provides a cotton fabric pretreatment process which comprises the following steps: cold pad-batch, water washing, working solution padding, ozone pretreatment, water washing and drying. The cotton fabric can be treated at normal temperature by using the assistant and ozone for treatment, the strength retention rate of the fabric is more than 90%, and by adopting the decolorizing method, about 60% of water and steam can be saved, 65% of assistant is saved, and about 55% of CO2 emission is reduced.

The invention is applicable to the technical field of China hemp fiber bleaching, and provides an intelligent China hemp fiber bleaching device which comprises a bleaching box and further comprises a transverse frame, an elastic telescopic cylinder, a guide sleeve, a guide roller, a supporting roller, a lifting plate, a telescopic cylinder and a transmission rod. The plurality of elastic telescopic cylinders synchronously contract towards the middle; when the telescopic cylinders drive the lifting plate to descend, the multiple elastic telescopic cylinders synchronously expand towards the two sides under the limiting effect of the strip-shaped holes on the transmission rods. And in the lifting movement process of the lifting plate, the buffer lifting assembly is used for extracting the bleaching agent in the bleaching box and conveying the bleaching agent to the hose in a buffer manner, and after the bleaching agent is conveyed through the transmission rod, the bleaching agent is finally sprayed out through the spray head and acts on the fiber materials. Through stable and dynamic S-shaped conveying of fiber materials and an intelligent buffer spraying mechanism, the bleaching efficiency and quality are remarkably improved.
