5. A method for recovering a residual liquid for processing a fabric, which is applied to the residual liquid recovery device for processing the fabric according to any one of claims 1 to 4, and is characterized in that: the method comprises the following specific steps:

the method comprises the following steps: firstly, the fabric to be dyed is conveyed inwards in production through a plurality of conveying rollers (4), the fabric passes through a dyeing cavity (3), and dyeing liquid in the dyeing cavity (3) dyes the fabric to finish dyeing;

step two: then, the dyed fabric is continuously driven to be conveyed to the left side, the liquid scraping mechanism is started, the liquid scraping mechanism clamps the fabric from the upper side and the lower side, liquid scraping treatment is carried out on the dyed fabric, and redundant dyeing liquid carried in the fabric is scraped out;

step three: the scraped residual liquid falls into a filtering mechanism at the bottom of the scraping liquid, and the filtering mechanism filters the dyeing residual liquid to remove the flock pollutants in the residual liquid;

step four: the residual liquid passing through the filtering mechanism is stored in the collecting mechanism and is kept stand;

step five: and the recovery mechanism is utilized to suck the upper residual liquid in the collection mechanism into the recovery mechanism, the residual liquid is continuously allocated again in the recovery mechanism, and after allocation is finished, the residual liquid is conveyed into the dyeing cavity (3) again to dye the fabric of the same batch for use.
