Description

Technical Field

[0001] The utility model relates to the technical field of shoe upper production, in particular to a photochromic TPU shoe upper. Background Art

[0002] With the development of outdoor sports, people's requirements for sports shoes are getting higher and higher. Consumers expect sports shoes to have beautiful colors on the basis of good comfort, durability and wear resistance. Therefore, the development of color-changing fabrics has a very broad prospect. However, the color-changing fabric products on the market usually use dyes or chemical dyes to modify and finish the yarns to obtain a good color-changing effect on the surface of the yarns. However, its shortcomings such as poor color fastness, poor sun resistance, reduced yarn transparency and strength have always been a problem that has plagued the industry.

[0003] TPU is a material between rubber and plastic. It not only has a unique molecular structure, but also has excellent mechanical properties, high elasticity, good wear resistance, and high strength. Due to its good comfort, light weight, good extensibility, easy processing and environmental protection, it is widely used in shoe materials and has good development prospects. Therefore, achieving photochromic effect on TPU yarn can also better meet the needs of consumers. Utility Model Content

[0005] The utility model aims to overcome the above-mentioned shortcomings and provide a photochromic TPU upper. The photochromic TPU yarn is obtained by mixing a photochromic raw material with a TPU raw material, and the photochromic TPU yarn is controlled to generate a desired pattern on an aluminum plate, and the pattern is transferred to the upper, so that the upper can present a pattern that changes with the intensity of light. The upper or lower layer of the pattern is also provided with a TPU layer for protecting and stabilizing the pattern, so that the pattern in the upper is more stable. The upper produced in this way has good heat resistance and light resistance, and has higher color intensity and better color concentration than the upper made of traditional chemical dyes. At the same time, because the specific pattern is made by yarn, the pattern has high flexibility, strong plasticity, and is green and degradable.

[0006] The utility model provides a photochromic TPU shoe upper, comprising a first protective layer, a stabilizing layer and a photochromic pattern layer which are sequentially stacked, the first protective layer, the stabilizing layer and the photochromic pattern layer which are sequentially stacked are integrated by hot pressing, and the photochromic pattern layer is formed by melting photochromic yarn.

[0007] In some embodiments, the photochromic yarn is made by uniformly mixing the photochromic material and the TPU material.

[0008] In some embodiments, the photochromic yarn includes a skin layer and an inner core, the inner core is a photochromic material, and the skin layer is a TPU material.

[0009] In some embodiments, the photochromic yarn is first drawn on an aluminum plate and then covered on the stabilizing layer by transfer printing.

[0010] In some embodiments, the aluminum plate is sprayed with a fluorine coating with polytetrafluoroethylene as a base resin.

[0011] In some embodiments, in the photochromic yarn, the proportion of the photochromic material accounts for 5-20% of the total mass of the photochromic yarn.

[0012] In some embodiments, the photochromic pattern layer is further covered with a second protective layer, and the second protective layer is made of TPU material.

[0013] In some embodiments, the first protective layer and the stabilizing layer are both made of high-transmittance TPU materials.

[0014] By adopting the above technical solution, the beneficial effects of the utility model are:

[0015] The utility model mixes a photochromic raw material with a TPU raw material to obtain a photochromic TPU yarn, sprays a fluorine coating with polytetrafluoroethylene as a matrix resin on an aluminum plate, controls the photochromic TPU yarn to generate a desired pattern on the aluminum plate, and transfers the pattern to the shoe upper, so that the shoe upper can present a pattern that changes with light intensity, and an upper or lower layer of the pattern is further provided with a TPU layer for protecting and stabilizing the pattern, so that the pattern in the shoe upper is more stable. The shoe upper produced in this way has good heat resistance and light resistance, and has higher color intensity and better color concentration than a traditional shoe upper made by chemical dyes. At the same time, because a specific pattern is made by yarn, the pattern has high flexibility, strong plasticity, and is green and degradable.
