Description

Technical Field

[0001] The present invention relates to an industrial anti-metal molten splash-proof clothing and its manufacturing process. Background Art

[0002] In modern industrial production, welding is widely used in industrial production such as steel production, oil and gas pipelines, pressure vessel manufacturing, shipbuilding, electric power, the automotive industry, and aerospace. During welding, professional welders usually operate with special welding equipment. During welding operations, metals will undergo high-temperature and high-heat reactions. If the operation is not careful, welders are easily scalded by high temperatures, and the clothes they wear may also catch fire and burn. In addition, metal droplets formed by melting metals at high temperatures may also splash onto the operator's body and clothes, posing a threat to safe production.

[0003] Due to the defects in the structural design of the protective clothing in the prior art, the blocking effect of the protective clothing on metal molten splash is not good, and it cannot sense the ambient temperature, resulting in certain safety problems. Summary of the Invention
