Problems solved by technology

[0007] 1. In method 1, when the three-layer mesh is directly subjected to hot-pressing treatment, the requirements for hot-pressing temperature are high, and the temperature requirement for hot-pressing is slightly lower than the melting point of the three-layer mesh fabric. If the temperature exceeds the melting point of the three-layer mesh fabric, it will cause The mesh is fused, and if the temperature is too low, it will not be able to form a hot-press pattern; and because the hot-pressing temperature is close to the melting point of the fabric, the mesh is easy to change color after hot-pressing; and the three-layer mesh after direct hot-pressing treatment is still The whole piece is soft, and it will only form hot-pressed patterns on the surface of the mesh, which still cannot meet the characteristic requirements of the upper material
[0008] 2. The processing technology of method 2 is complicated, and different silk screen templates need to be produced in advance. The bonding force between the adhesive layer and the mesh is weak, and it is easy to age and degumming. Moreover, the whole mesh after heat treatment is relatively hard, which still cannot meet the requirements of shoe uppers. Locally soft and partially hard characteristics required by the material

Embodiment approach 1

[0048] The three-layer mesh is subjected to padding treatment, the padding solution used in the padding treatment is a water-based polyurethane solution with a concentration of 10% by mass, and after the padding treatment, the three-layer mesh is partially treated with a hot pressing temperature of 170 degrees Celsius. Heat press setting treatment.

[0049] Among them, water-based polyurethane is a new type of polyurethane system that uses water instead of organic solvents as the dispersion medium, also known as water-dispersed polyurethane, water-based polyurethane or water-based polyurethane;

[0050] According to particle size and appearance, it can be divided into polyurethane aqueous solution (particle size0.1 micron, appearance cloudy);

[0051] What is used in this embodiment is a 5-200 micron polyurethane emulsion.

[0052] According to whether the side chain or the main chain of the polyurethane molecule contains ionic groups, that is, whether it is an ionomer (iono...

Embodiment approach 2

[0059] The difference from Embodiment 1 is that in this embodiment, the padding solution is a water-based polyurethane solution with a mass percent concentration of 20%, the particle size of the water-based polyurethane solution is 5 μm, and the temperature of the water-based polyurethane solution is 40 degrees Celsius. The soaking time of the first layer of mesh in the aqueous polyurethane solution is 3 minutes, and the dry pressure of the three-layer mesh is 450N / cm;

[0060] The drying temperature of the three-layer mesh cloth is 110 degrees Celsius;

[0061] The temperature of the hot-pressing die head is 160 degrees centigrade when the three-layer mesh cloth is hot-pressed and shaped.

Embodiment approach 3

[0063] The difference from Embodiment 1 is that in this embodiment, the padding solution is an aqueous polyurethane solution with a mass percent concentration of 30%, the particle diameter of the aqueous polyurethane solution is 100 μm, and the temperature of the aqueous polyurethane solution is 45 degrees Celsius. The soaking time of the first layer of mesh in the aqueous polyurethane solution is 3 minutes, and the dry pressure of the three-layer mesh is 460N / cm;

[0064] The drying temperature of the three-layer mesh cloth is 120 degrees Celsius;

[0065] The temperature of the hot-pressing die head is 165 degrees centigrade when the three-layer mesh cloth is hot-pressed and shaped.

Abstract

The invention discloses a treatment method for flexibly shaping a three-layer mesh fabric. The treatment method for flexibly shaping the three-layer mesh fabric comprises the following steps of carrying out padding treatment on the three-layer mesh fabric, wherein a padding solution adopted for the padding treatment is an aqueous polyurethane solution of which the percentage concentration by mass is 10 to 40 percent; the particle sizes of aqueous polyurethane are more than 1 microns but less than 200 microns. By using the treatment method provided by the invention, not only can the original softness of the three-layer mesh fabric be retained, but also the flexible shaping can be carried out through hot-pressing treatment; a hot-pressing temperature is large in controllable range, and is easy to control; further, the problems of the fusing and the discoloration of the three-layer mesh fabric can be solved.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a three-layer mesh cloth and a flexible shaping treatment method thereof. Background technique [0002] The three-layer mesh cloth includes an upper surface layer, a lower surface layer and a spacer layer connected between the two by warp knitting. The looseness and thickness of the fabric depend on the connecting yarn and weaving method between the upper layer and the lower layer. The fiber type of the yarn can be warped according to the order or product needs. The three-layer mesh fabric is usually used in the production of outdoor shoes to form a lightweight, tough, comfortable and breathable upper structure. [0003] In the upper material, by requiring the material of the toe to have better softness, the material of the side and the heel of the shoe has a certain hardness to support the upper so that it has a better shape and better comfort. sex. However, the existing three-layer ...
