Multi-layer self-adhesive melt-blown cloth with sterilization and virus killing functions, production process and production line of multi-layer self-adhesive melt-blown cloth

Abstract

The invention relates to a multi-layer self-adhesive melt-blown cloth with sterilization and virus killing functions, a production process and a production line thereof, the multi-layer self-adhesive melt-blown cloth comprises more than two layers of melt-blown cloth, a traditional Chinese medicine layer or a chemical sterilization and virus killing component layer is arranged between every two layers, and the multi-layer structure is overlapped up and down and self-adhered. After a fiber cloth layer is formed on a melt-blowing production line adopting more than two melt-blowing nozzles, a traditional Chinese medicine layer or a chemical sterilizing and virus-killing component layer is sprayed by an atomizing or spraying device of traditional Chinese medicine or chemical liquid medicine, and meanwhile, drying and electrostatic electret are performed by an air suction drying device. The cloth is simple in structure and convenient to manufacture, has the functions of efficiently adsorbing, filtering and killing fine particulate matters, viruses and bacteria, and has the advantages of long shelf life and the like.

Description

technical field [0001] The invention relates to melt-blown cloth technology, specifically a multi-layer self-adhesive melt-blown cloth with bactericidal and virus-killing functions, a production process and a production line thereof. Background technique [0002] The traditional melt-blown cloth with electret masterbatch only has simple filtration and adsorption functions for viruses, particles, and bacteria after passing through the electret device, and has no bactericidal and virus-killing functions; while some currently on the market use copper oxide to add melt-blown materials To achieve the function of sterilization and virus elimination, but copper oxide is a heavy metal that is easy to cause heavy metal poisoning, users have concerns and cannot be popularized; in addition, traditional Chinese medicine or chemical agents are added to the melt-blown cloth, and direct soaking, surface spraying, spraying, etc. Processes, many processes and simple and rough solutions make ...

Problems solved by technology

[0002] The traditional melt-blown cloth with electret masterbatch only has simple filtration and adsorption functions for viruses, particles, and bacteria after passing through the electret device, and has no bactericidal and virus-killing functions; while some currently on the market use copper oxide to add melt-blown materials To achieve the function of sterilization and virus elimination, but copper oxide is a heavy metal that is easy to cause heavy metal poisoning, users have concerns and cannot be popularized; in addition, traditional Chinese medicine or chemical agents are added to the melt-blown cloth, and direct soaking, surface spraying, spraying, etc. Processes, many processes and simple and rough solutions make the sterilization and virus killing functions of traditional Chinese medicine or chemical agents unable to last for a long time. What's more, the original static electricity of the melt-blown cloth is weakened by soaking, spraying, spraying and other processes after the finished melt-blown cloth is finished. The adsorption function is almost lost, and the adsorption and filtration function of the melt-blown cloth to particulate matter, parvovirus and bacteria is lost, and the gain outweighs the gain

For example, the application number is 202011122267.X, a kind of steam spraying method, production line and application of melt-blown cloth that can inactivate viruses. High cost; for example, the patent application number 202010900946.9, a sterilizing and anti-fouling melt-blown cloth and its processing technology, uses immersion in the mixed solution and then drying, which also has these fundamental problems
