Description

Technical Field

[0001] The utility model relates to the technical field of synthetic leather, in particular to anti-fouling PU synthetic leather. Background Art

[0002] Most of the synthetic leathers on the market are made of organic solvent-based PU resin as the base layer and the surface layer, that is, PU leather; this type of PU resin is made by solvent polymerization using toluene, xylene, acetone, butanone, ethyl acetate, dimethylformamide, etc. as solvents. These organic solvents are all harmful substances. In the process of foaming synthetic PU leather, gases harmful to the human body are produced, which affects health. In addition, harmful substances are also discharged through water and air, seriously polluting the environment and having poor environmental protection.

[0003] In the prior art, the existing synthetic leather has poor ventilation effect. When in use, it is easy to breed bacteria, which will not only cause great pollution to the environment, but also cause great harm to human health. For synthetic leather, its surface is smooth and has certain waterproof properties, but the waterproof function of the synthetic leather surface is limited without improvement and strengthening, resulting in oil stains adhering to the surface of the synthetic leather, which is difficult to clean. In addition, the common synthetic leather has poor ventilation effect compared with woven fabrics. Therefore, after synthetic leather is used to make clothing, its poor ventilation will seriously affect the comfort of wearing. In the prior art, artificial leather is also often used on some clothes, but generally Leather clothes are mostly worn in cold weather, and cold weather easily accumulates static electricity on synthetic leather, which causes static electricity to absorb dust or impurities in the outside world, making the synthetic leather easy to get dirty. Existing synthetic leather is generally made by coating a negative ion coating on the outer surface of the synthetic leather. In actual use, since the negative ion coating is on the outermost surface, it is easy to come into contact with friction and fall off, affecting the use time of the negative ion function of the synthetic leather. At the same time, after the negative ion coating is set, it is inconvenient to perform anti-fouling treatment on the synthetic leather, resulting in troublesome cleaning of the synthetic leather. In the prior art, due to less attention paid to the elasticity of the synthetic leather, the synthetic leather indirectly feels poor and has a poor use effect. Utility Model Content
