ABSTRACT:
Knitted cotton fabrics in tubular form are impregnated to 20 to 35% wet add-on of crosslinking agent by any of several techniques including sprinkling, spraying, printing, or slop padding the solution of crosslinking agent to the outer surfaces of the fabric tube, or transferring the solution of crosslinking agent from impregnated material to the outer surfaces of the fabric tube, followed by a mechanical agitation step wherein the impregnated tubes are mechanically agitated at elevated temperatures under closed conditions, thereby eliminating agent migration toward fabric surfaces during drying of the cotton containing knitted fabrics in chemical treatments for smooth-drying properties and dimensional stabilization.
