Embodiment

[0024] The preparation process of the shoe upper with self-cleaning function of the present invention comprises the following steps:

[0025] (1) Put nano-titanium dioxide powder and monomer methyl methacrylate into a container, add water and mix evenly under ultrasonic action;

[0026] (2) Add polyethylene glycol, azobisisobutyronitrile and allyl methacrylate, under the protection of nitrogen, at 80-90°C, at the speed of 400-600r / min, stir the reaction for 3-5h, and finally washing with water, suction filtration, and vacuum drying to obtain photocatalytic titanium dioxide microcapsules;

[0027] (3) adding the photocatalytic titanium dioxide microcapsules into the thermoplastic polyurethane slurry, and putting polyethylene glycol into it simultaneously to obtain a thermoplastic polyurethane wet-process slurry;

[0028] (4) After coating the thermoplastic polyurethane wet-process slurry on the base cloth, solidify, wash, and dry to form a semi-finished polyurethane synthetic ...

Abstract

The invention discloses a process for preparing shoe uppers with a self-cleaning function. Nano-titanium dioxide powder and monomer methyl methacrylate are put into a container, and water is added to mix evenly under the action of ultrasound; polyethylene glycol, azo Diisobutyronitrile and allyl methacrylate, stirred and reacted for 3-5 hours under nitrogen, washed, filtered, and vacuum-dried to obtain photocatalytic titanium dioxide microcapsules; adding photocatalytic titanium dioxide microcapsules to thermoplastic polyurethane slurry , and put polyethylene glycol at the same time to prepare thermoplastic polyurethane wet-process slurry; apply thermoplastic polyurethane wet-process slurry to the base fabric, solidify, wash, and dry to form polyurethane synthetic leather semi-finished products; tencel fiber and corn The fibers are blended to obtain a blended layer, and the blended layer will be connected to the inner side of the semi-finished polyurethane synthetic leather, and the nano-copper oxide coating is evenly coated on the outer side of the semi-finished polyurethane synthetic leather; irradiated under sunlight for 20-25 hours to obtain the finished product.

Description

technical field [0001] The invention relates to the field of production and manufacturing, in particular to a preparation process of a vamp with a self-cleaning function. Background technique [0002] Shoes have a long history of development. About 5,000 years ago in the Yangshao culture period, the most primitive shoes made of animal skins appeared. Shoes are a tool for people to protect their feet from injury. The earliest people invented fur shoes in order to overcome special circumstances and prevent their feet from being uncomfortable or injured. Shoes have developed to the present, and they have formed what they are now. Shoes of various styles and functions can be seen everywhere. [0003] Yet shoes are very troublesome in daily cleaning, and shoes are often dirty easily again, therefore, a kind of shoes with self-cleaning function are in urgent need. Contents of the invention [0004] The technical problem to be solved by the present invention is that the exis...
