The invention discloses a using method of a textile grey fabric transferring and stretching mechanism, and belongs to the field of textile processing mechanical equipment. The textile grey fabric transferring and stretching mechanism comprises a transferring bracket, a fabric guiding roller, a guiding square bar, a stretching mechanism, an upper rotary disk, a lower rotary disk and a stretching motor, wherein the fabric guiding roller is horizontally and rotatably connected with the transferring bracket; guiding sleeves are horizontally and glidingly arranged at two sides of the guiding squarebar, respectively; the stretching mechanism is horizontally arranged at the lower sides of the guiding sleeves; a lower reciprocating lever is arranged between the lower rotary disk and a transferring bar; an upper connection chain wheel and a lower connection chain wheel are provided with transferring chains; a lower reciprocating lever is arranged between the upper rotary disk and a translationplate; a plurality of upper compression rolls are horizontally, uniformly and rotatably connected with the upper side of a stretching bracket; and a plurality of lower compression rolls are horizontally, uniformly and rotatably connected with the upper side of a lifting plate. The textile grey fabric transferring and stretching mechanism is reasonable in structural design, and is capable of rapidly and conveniently stretching grey fabrics in an efficient, stable and uniform way so as to improve the grey fabric stretching efficiency and quality and then satisfy the requirements of production and using.
