Description
Technical Field
The utility model relates to the technical field of medical protection, in particular to a breathable composite film for protective clothing.
Background
The medical protective clothing is generally made of a single-layer or double-layer nonwoven web, or a composite nonwoven fabric which is formed by adding a plastic film layer between two layers of nonwoven fabrics and then bonding the two layers of nonwoven fabrics with glue. The former has good air permeability but poor water resistance, which is easy to cause invasion of bacteria and virus, and the latter has improved water resistance due to the presence of the middle plastic film, but has poor air permeability and is very uncomfortable to wear and use.
Therefore, how to provide a composite film for protective clothing with good water resistance and air permeability is a technical problem that needs to be solved urgently by the technical personnel in the field.
SUMMERY OF THE UTILITY MODEL
The utility model aims to: aiming at the problems in the prior art, the composite film for the protective clothing has good air permeability and can absorb water and prevent sweat.
In order to achieve the purpose, the utility model adopts the following technical scheme:
a breathable composite film for protective garments, comprising: a surface cloth layer, a waterproof breathable layer, a protective layer and a base cloth layer which are sequentially bonded from outside to inside.
Preferably, the surface cloth layer is aramid fiber 1414.
The outmost layer is a surface cloth layer which is made of aramid fiber 1414 materials and has good wear-resistant, heat-proof and anti-cutting effects.
Preferably, the waterproof breathable layer is of a composite structure of aramid spunlace felt and a PTFE film.
Preferably, the air permeability of the waterproof breathable layer is 90-100g/m2/h。
The preferable beneficial effects are as follows: the PTFE membrane has a fibril microporous structure, the porosity is more than 85%, and the waterproof and breathable effects of the waterproof and breathable layer are improved by compounding the PTFE membrane with the aramid spunlace felt.
Preferably, the protective layer is an activated carbon fiber cloth containing an antibacterial agent.
Preferably, a plurality of micropores are formed in the protective layer.
The preferable beneficial effects are as follows: the activated carbon fiber cloth can improve the absorption energy of sweat, and the antibacterial effect of the protective clothing can be improved by adding the antibacterial agent
Preferably, the base cloth layer is woven fabric blended by aramid fibers and glass fibers.
According to the technical scheme, compared with the prior art, the waterproof and breathable composite film for the protective clothing effectively overcomes the defects of common medical protective clothing on the market by arranging the waterproof and breathable layer and the protective layer, the waterproof and breathable effect is good when the protective clothing is used, the resistance to bacteria can be further improved by arranging the protective layer, and meanwhile, the adsorption capacity to sweat can be improved by adopting the activated carbon fiber cloth, so that the comfort of the protective clothing is improved.
