Problems solved by technology

[0009] 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

preparation example Construction

[0018] The preparation method of a double-sided jacquard knitted shoe upper of the present invention is realized by the following steps:

[0019] 1. The conventional wrapping process is used to wrap the spandex with the hot-melt filament, that is, the spandex is used as the core, and the hot-melt filament is wound around the spandex in a unidirectional spiral to obtain a hot-melt filament frame; 10-15wt%, thermal fuse accounts for 85-90wt%; thermal fuse adopts low melting point nylon yarn or low melting point polyester yarn.

[0020] 2. The hot-melt filament tension frame obtained in step 1 is sent into the computerized flat knitting machine together with the conventional knitting yarn to be knitted into a semi-finished product of double-sided jacquard knitted upper of a preset pattern; 5-50wt%, conventional knitting yarns account for 50-95wt%; the conventional knitting yarns are any one or more of elastic threads, polyester, nylon, and cotton; when multiple types are selected...

Embodiment 1

[0024] Example 1: 65 wt % of elastic threads, 17.7 wt % of polyester, and 17.3 wt % of hot-melt wire drawer.

Embodiment 2

[0025] Example 2: Polyester 57.49wt%, hot-melt wire drawer 42.51wt%.

Abstract

The invention discloses a preparation method of a two-sided jacquard knitting vamp, which adopts thermofuse lycra and conventional knitting yarns to be knitted into the two-sided jacquard knitting vamp. During knitting, the thermofuse lycra hooks and knits two layers of the vamp together.During thermoforming treatment, thermofuses are molten and penetrate into fibers of the vamp, and after cooling, the vamp can have better compactness and flatness.During the cooling, shrinkage and tightening of the vamp can be promoted by the action of elasticity of spandex, so that face fabric of the vamp is more compact and denser.Furthermore, after shoes manufactured by the vamp are washed for many times, even if a part of thermofuses are disconnected, the spandex can still work, hook and knit the two layers of the vamp together firmly,therebyensuringthat the two layers of the vamp cannot be separated from each other.

Description

technical field [0001] The invention relates to a shoe upper, in particular to a preparation method of a double-sided jacquard knitted upper. Background technique [0002] The structure of a sports shoe includes a sole and an upper, and the upper is covered on the sole to form a shoe. For traditional sports shoes, the upper is generally made of artificial leather. The pattern on the upper is made of artificial leather of different colors. The more complex the pattern, the more troublesome it is to make. has certain limitations. [0003] The integrated knitted fabric has the advantages of breathability and lightness, and 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 loosen and deform, and the materials used as shoe uppers need to have a certain degree of firmness and flatness. Therefore, existing knitted fabrics cannot be directly appli...
