Detailed Description

The invention provides a medical protective clothing fabric, which comprises a surface layer 1 and an inner layer 2 which are bonded through bonding points; the surface layer 1 is woven by conductive fibers 11 and polyester filaments, and is subjected to antibacterial, water repellent and softening treatment, and the thickness of the surface layer is 0.2-0.6 mu m; the inner layer 2 is composed of a high polymer film, and the thickness of the inner layer is 5-15 mu m.

In a preferred embodiment of the present invention, the surface layer 1 is woven by warp yarns and weft yarns, the warp yarns are polyester filaments, the weft yarns comprise the polyester filaments and conductive fibers 11, and the conductive fibers 11 are arranged one by one at intervals of 1-5 cm.

The conductive fiber 11 is a carbon fiber, and the surface thereof is also coated with a conductive coating.

The antibacterial agent adopted in the antibacterial treatment is a nano-silver antibacterial agent, the water repellent agent adopted in the water repellent treatment is any one of a C6 water repellent agent, a C8 water repellent agent or an organic silicon water repellent agent, and the softening agent adopted in the softening treatment is a polyamide type softening agent.

The antibacterial agent, the water repellent agent and the softening agent are all prepared by dissolving in a solvent, the solvent is water, the mass ratio of the antibacterial agent to the solvent is 1% -4%, the mass ratio of the water repellent agent to the solvent is 2% -8%, and the mass ratio of the softening agent to the solvent is 1% -5%.

The high polymer film is any one of a polytetrafluoroethylene film, a polyurethane film or a polyethylene film and is provided with air-permeable micropores of 0.1-15 mu m.

The surface layer 1 and the inner layer 2 are bonded in a dotted manner by reactive polyurethane.

The surface layer 1 is a woven fabric woven by warps and wefts, and is attached to the inner high-molecular polymer film, so that the fabric has excellent physical properties and high strength performance, can be repeatedly used, and can still keep excellent protective performance after being washed by chlorine-containing disinfectant for multiple times.

The pore diameter of the micropores of the inner layer 2 high-molecular polymer membrane is smaller than the diameter of water drops, so that the permeation of blood or other body fluids can be prevented, and on the other hand, the pore diameter of the micropores is larger than the diameter of water vapor molecules, so that the water vapor molecules can freely pass through, and the fabric has better moisture permeability.

In order that the invention may be better understood, the invention will now be further described with reference to the following examples.
