Problems solved by technology

[0007] The purpose of the present invention is to provide a method for preparing double-sided jacquard knitted shoe uppers. The double-sided jacquard knitted shoe uppers prepared by this method overcome the problem of poor hand feeling caused by the use of auxiliary agents at present, and can still be maintained after repeated washing. Good compactness and flatness, and can ensure that the two layers of the upper will not separate from each other

Embodiment 1

[0017] The method for preparing double-sided jacquard knitted shoe uppers of the present invention is achieved through the following steps:

[0018] (1) Spandex is covered with thermal fuse using conventional yarn wrapping process to obtain a thermal fuse frame; in the thermal fuse frame, spandex accounts for 15wt% and thermal fuse accounts for 85wt%;

[0019] (2) Send the hot fuse frame obtained in step 1 together with conventional knitting yarns into a computerized flat knitting machine to knit into a semi-finished double-sided jacquard knit upper half-finished product; the hot fuse frame in the double-sided jacquard knit upper Accounted for 10wt%, conventional knitting yarn accounted for 90wt%:

[0020] (3) The semi-finished double-sided jacquard knitted shoe upper obtained by knitting in step two is subjected to heat setting treatment in an environment of 110°C, and the finished double-sided jacquard knitted shoe upper is obtained after cooling.

[0021] In the present invention, ...

Embodiment 2

[0024] A method for preparing double-sided jacquard knitted shoe uppers is achieved through the following steps:

Abstract

The invention discloses a preparation method of a double-faced jacquard knitted vamp. The method is characterized by knitting the double-faced jacquard knitted vamp by using a heat fusion silk drawing frame and conventional knitting yarns; during knitting, the heat fusion silk drawing frame is used for interweaving two layers of the vamp together; during heat setting treatment, heat fusion silks are fused and permeate into vamp fiber; after being cooled, the vamp is high in compactness and flatness; in the cooling process, shrinkage and tightness of the vamp can be accelerated by an elastic effect of spandex, so that a vamp fabric is more compact and dense; furthermore, after shoes made of the vamp are repeatedly washed, the spandex still sticks to a post and firmly interweaves the two layers of the vamp even if some of the heat fusion silks are broken, so that the two layers of the vamp do not separate from each other.

Description

Technical field [0001] The invention relates to shoe uppers, in particular to a method for preparing double-sided jacquard knitted shoe uppers. Background technique [0002] The structure of sports shoes includes a sole and an upper, and the upper is wrapped on the sole to form a shoe. Traditional sports shoes generally use artificial leather uppers. The patterns on the uppers are made of artificial leather with different color blocks. The more complicated the patterns, the more troublesome it is to make. Limited by the existing technology, the choice of patterns The above has certain limitations. The one-piece knitted fabric has the advantages of breathability and lightness. Various personalized and complex patterns can be woven through the computerized flat knitting machine, and the design of the pattern is not limited. However, knitted fabrics are easy to slack and deform, and the material for shoe uppers needs to have a certain degree of tightness and flatness. Therefore, t...
