Method of finishing of greige woven fabrics
Abstract
Abstract This invention pertains to an improved method and apparatus for finishing greige goods in a single processing range. The invention is applicable particularly to the finishing of highshrinkage fabrics such as denim. The apparatus of the invention includes the following combination of devices for sequentially processing the fabric: a padder for impregnating the fabric with a desired liquid finishing preparation; a scray for collecting and storing temporarily the fabric when it is discharged from the padder; a free-rolling heated can assembly for partially drying the fabric received from the scray, and having control rollers at its input and output sides for controlling the tension of the fabric as it is advanced through the can assembly; a first compressive-preshrinkage unit for preshrinking the fabric an amount equal to about one half of its total potential-shrinkage characteristic; a driven second heated can assembly for further drying the fabric; a second compressive preshrinkage unit for shrinking the fabric a final amount to comply with predetermined standards, such as, established Sanforized label standards and a driven third can assembly for fully drying the fabric for discharge to a storage facility.
