Problems solved by technology

At present, high-adhesive hot-melt adhesive film is often used to bond the edge strips for bonding and wrapping, which has the problem of weak adhesion and poor edge wrapping effect
Moreover, the seamless hemming uses the hemming machine to heat-melt the hemming strip on the edge of the body material. For the edge of the body with a large hemming arc or many sharp turns, the hemming cannot be in place, and problems such as curling and popping are prone to occur.
At the same time, when these hemmed materials are applied to the upper, the adhesion tensile test cannot meet the quality requirements of the shoe
In addition, limited by the production process, traditional edging strips generally have problems such as single color, no pattern design, boring and single style, and not beautiful enough.

Embodiment 1

[0049] In an exemplary embodiment of the method according to the present invention, a method such as Figure 5 Upper body shown with multicolor binding. The method specifically contains the following steps:

[0050] According to the shape of the vamp to be hemmed, a hemming hot-cutting mold and a flat ironing peg mold that are adapted to the shape of the vamp to be hemmed are set on the hemming machine. Manufacturing is a very mature technology. According to the cutting design of the upper, it can be entrusted to other open mold main bodies for processing or self-manufactured. Each upper to be hemmed should have a corresponding hemming and hot-cutting mold and a flat ironing peg mold. This can be achieved. Large-scale, repetitive production applications.

[0051] Take the edge wrapping strip and strip TPU prepared in advance with preset colors and patterns. It should be noted here that the width of the strip TPU should be larger than the width of the edge wrapping strips of ...

Embodiment 2

[0058] Different from the above-mentioned embodiment, a strip of TPU with a width of 12 mm and a thickness of 0.4 mm can also be used to fold in half (then a TPU adhesive strip with a width of about 6 mm is obtained) to cover the edge of the upper to be hemmed, and perform high-frequency eager cutting. Cut off about 3mm wide TPU edging leftovers and remove to obtain the to-be-wrapped shoe upper containing TPU adhesive strips. When performing high-frequency heat cutting, set the fusing temperature to 110°C, the fusing time to 5s, the cooling temperature to 30°C, the cooling time to 6s, and the pressure to be 4MPa.

[0059]Fold the hemming strip with the preset color and pattern with a width of 6mm in half (then get the hemming with color and pattern with a width of about 3mm) and wrap it on the to-be-wrapped shoe containing the TPU adhesive strip obtained in the previous step The edge of the surface is wrapped and hot pressed in turn. During hemming, set the heating temperatur...

Embodiment 3

[0061] Different from the method of Embodiment 1, this embodiment adopts a strip of TPU with a width of 14 mm and a thickness of 0.5 mm to be folded in half (then a TPU adhesive strip with a width of about 7 mm is obtained) to cover the edge of the vamp to be hemmed, and the height is applied. Frequently and eagerly, cut off about 2mm wide TPU edging and leftovers to get the upper to be edging containing TPU adhesive strips. When performing high-frequency heat cutting, set the fusing temperature to 100°C, the fusing time to 6s, the cooling temperature to 25°C, the cooling time to 7s, and the pressure to be 4MPa.

[0062] Fold the hemming strip with the preset color and pattern with a width of 9mm in half (then get the hemming with color and pattern with a width of about 4.5mm) and wrap it on the to-be-wrapped edge containing the TPU adhesive strip obtained in the previous step The edge of the upper is wrapped and hot pressed in turn. During hemming, set the heating temperatur...

Abstract

The invention relates to the technical field of edge covering in the textile industry, in particular to a multicolor edge covering manufacturing process, an edge covering product and application of the multicolor edge covering product. The multi-color covered edge manufacturing process comprises the following steps that according to the shape of a to-be-covered body, a covered edge hot cutting mold and a flat ironing hanging nail mold which are matched with the shape of the to-be-covered body are arranged; preparing an edge covering strip with a preset color and pattern, wherein the manufacturing method of the edge covering strip with the preset color and pattern comprises the steps of fixing the edge covering strip on a transfer printing machine bedplate and transferring the preset color and pattern on the edge covering strip; preparing strip-shaped TPU, wherein the width of the strip-shaped TPU is greater than that of the edge covering strip with the preset color and pattern; folding the strip-shaped TPU and coating the strip-shaped TPU on the edge of the body to be subjected to edge covering, and performing high-frequency hot cutting to obtain the body to be subjected to edge covering containing the TPU adhesive strip; folding an edge covering strip with a preset color and pattern, covering the edge of the to-be-covered body containing the TPU adhesive strip with the edge covering strip, and sequentially carrying out edge covering and hot pressing to obtain the body containing the multi-color covered edge.

Description

technical field [0001] The present application relates to the technical field of hemming in the textile industry, and more particularly to a multi-color hemming production process, a hemming product and applications thereof. Background technique [0002] Hemming refers to folding back the edge of the surface material of the body and fixing it to the part of the body, or overlapping the edges with a single material or multiple pieces of material and aligning the edges to wrap the body. Hemming is more common in light industrial production processes and is used in the processing of a variety of textile products. Examples include, but are not limited to, garment necklines, cuffs, hem edges, and vamp edges. Common hemming techniques include sewing hemming and fitting hemming. The effect of sewing hemming, such as outer piping and hemming, is a test of the craftsman's hemming skills. Due to the limitation of the skill proficiency of the sewing hemmers, it is not suitable for t...
