Controllable moisture-permeable positive-pressure protective clothing system

Abstract

The invention provides a controllable moisture-permeable positive-pressure protective clothing system, which can provide protection for effectively blocking infection of bacteria, viruses, body fluid and the like for a wearer, also has efficient dehumidification and perspiration functions, and improves the long-term working comfort of the wearer. The protective clothing system adopts an external electric fan to convey clean air into a positive-pressure head cover, upper garment sleeves of the protective clothing and trouser leg parts of trousers are made of high-moisture-permeability functional fabric with a breathable function, and a low-pressure area in the protective clothing system is formed; clean air entering the positive-pressure head cover controllably flows from a high-pressure area in the positive-pressure head cover to the low-pressure area in the protective clothing system in a manner of being mixed with water vapor volatilized by human sweat and high-humidity air exhaled by people, and air is mainly and stably leaked to the external atmospheric environment from high-moisture-permeability functional fabric in the low-pressure area, micro-positive pressure of 30-130 Pa can be formed in the protective clothing, and the effective dehumidification capacity of the controllable moisture-permeable positive pressure protective clothing system calculated according to the surface area of the human body is larger than 9000 g / (m<2>*d).

Description

technical field [0001] The invention belongs to the field of protective clothing, in particular to the field of protective clothing with perspiration and dehumidification functions. Background technique [0002] For medical staff, airports, and customs quarantine personnel exposed to infectious or toxic environments, high-level protection is required. Although traditional disposable protective clothing can provide a certain barrier protection performance, it is stuffy after wearing Insensitivity is more serious, and the sweat volatilized by the wearer cannot be discharged in time and effectively, which seriously affects the heat dissipation and combat effectiveness of the human body. How to ensure that while effectively blocking infections such as bacteria, viruses, body fluids, and blood, it can also have effective dehumidification and perspiration functions, and protective clothing that improves the long-term work comfort of wearers is still relatively lacking.

[0002] For medical staff, airports, and customs quarantine personnel exposed to infectious or toxic environments, high-level protection is required. Although traditional disposable protective clothing can provide a certain barrier protection performance, it is stuffy after wearing Sweat is more serious, and the sweat volatilized by the wearer cannot be discharged in a timely and effective manner, which seriously affects the heat dissipation and combat effectiveness of the human body.

How to ensure that while effectively blocking infections such as bacteria, viruses, body fluids, and blood, it can also have effective dehumidification and perspiration functions, and protective clothing that improves the long-term work comfort of wearers is still relatively lacking.
