One-piece-vamp manufacture method and one-piece-woven-vamp

A one-piece-vamp manufacture method comprising the following steps:

• (1) weaving preparation:
• arranging different required raw material color yarn, hot melt silk and stretch yarn at a main color opening yarn feeding orifice, a match color opening yarn feeding orifice and a stretch yarn feeding orifice according to vamp patterns and process requirements, loading written program into a vamp machine, and inputting parameters corresponding to the vamp patterns and process requirements;
• (2) weaving U shape tube fabric:
• one side of the U shape tube fabric being an outer vamp, the other side being an inner vamp, both the outer vamp and the inner vamp being of a tube shape, a turn in the middle of the U shape tube fabric being a shoe opening part where the inner vamp and the outer vamp intersect;
• the vamp machine weaving in an order of a starting opening, an outer toe cap, an outer shoe body, an outer heel, an outer shoe opening to an inner shoe opening, an inner heel, an inner shoe body, an inner toe cap, during the course of weaving, achieving technical effects of local jacquard and local texturing at portions of the outer vamp;
• (3) stitching an inner toe seam:
• grasping the woven U shape tube fabric to a stitching device by an automatic robot arm, locating an inner toe opening at a needle position of the stitching device, performing aligned automatic stitching along the inner toe opening to form the inner toe seam;
• (4) stitching the outer toe seam:
• sucking the U shape tube fabric to an outlet opening through a suction pipe, taking the U shape tube fabric where the inner toe seam has already been stitched from the outlet opening, stitching the outer toe seam;
• (5) forming a one-piece-vamp semifinished product:
• overlapping the inner vamp and the outer vamp by extending the inner vamp into the tube of the outer vamp in the shoe opening part, forming a two-layer one-piece-vamp semifinished product;
• and
• (6) performing reshaping, setting and shape fixing on the vamp:
• putting the one-piece-vamp semifinished product on a shoe tree, using steam to perform scalding, making adjustment to the vamp and patterns for position alignment during the course of scalding, melting the hot melt silk to adhere the inner and outer vamps to each other as one piece, taking the shoe tree out after cooling, and forming the one-piece-vamp.
