Integrally-formed knitted heel shoe, heel shoe upper and knitting process thereof
Technical Field
The invention relates to the technical field of shoe knitting, in particular to an integrally-formed knitted heel shoe, a heel shoe vamp and a knitting process thereof.
Background
The fully knitted vamp has become a new series of products of the vamp, has the advantages of light weight, ventilation, variable colors and the like, and is popular in the market. However, the conventional knitted vamp is generally made of a plane fabric, a plurality of unfolded shoe-shaped vamps are arranged on the plane fabric, jacquard patterns, hollow holes and the like are designed at corresponding positions on the shoe-shaped vamps, and then the vamps are cut out by a laser machine. But the laser machine is tailor and is wasted time, and equipment cost is high, and some vamps still will carry out the secondary laser after carrying out the rust flower or laminating with other surface fabrics and tailor, and production technology is loaded down with trivial details, can waste a large amount of corner clouts moreover, needs accurate car worker when plane vamp is connected with the sole, otherwise can influence the size and the version type of shoes, and the shoe size is standard unified inadequately, influences travelling comfort and outward appearance, and these all make the manufacturing cost of shoes high. In addition, the common knitted vamp surface is soft in fabric, the stiffness of the vamp is not enough, the vamp is easy to collapse, and the appearance quality of the vamp is affected.
