Description
Technical Field
The invention belongs to the technical field of medical supplies, and relates to a processing method of a special fabric for medical isolation protective clothing.
Background
The medical isolation protective clothing refers to protective clothing used by medical staff (doctors, nurses, public health staff, cleaning staff and the like) and people entering specific medical and health areas (such as patients, hospital visitors, staff entering infected areas and the like). The function of the dust remover is to isolate germs, harmful ultrafine dust, acid-base solution, electromagnetic radiation and the like, ensure the safety of personnel and keep the environment clean. Besides the specification and safety requirements of the material itself, the performance of the medical isolation protective clothing mainly includes the aspects of protection, comfort, physical and mechanical properties, etc.
The protective property is the most important performance requirement of the medical isolation clothes, and mainly comprises the aspects of liquid barrier, microorganism barrier, barrier to particulate matters and the like. The liquid barrier property means that the medical isolation clothes can prevent the permeation of water, blood, alcohol and other liquids, and has the hydrophobicity of more than 4 grades so as to prevent clothes and human bodies from being stained. The virus carried by the blood, body fluid and other secretions of the patient in the operation process is prevented from being infected to medical personnel. Microbial barrier properties include barriers to bacteria and viruses. The barrier to bacteria is primarily intended to prevent contact transmission (and back-propagation) of medical personnel to the wound surface of a patient during surgery. The virus barrier is mainly used for preventing medical staff from contacting blood and body fluid of patients, and viruses carried in the medical staff cause cross infection between doctors and patients. Particulate matter barrier means that viruses transmitted through air are prevented from being inhaled in the form of aerosol or attached to the surface of skin to be absorbed by human body.
Comfort includes breathability, water vapor permeability, drape, mass, surface thickness, electrostatic properties, color, light reflectance, odor, skin sensitization, and the like. The most important is air permeability and moisture permeability, in order to enhance the protection effect, the fabric of the isolation suit is usually subjected to lamination or laminating treatment, so that the fabric is heavy, poor in air permeability and moisture permeability, and not beneficial to perspiration and heat dissipation after long-term wearing. The antistatic property is required to prevent the disadvantage that the static electricity in the operating room causes the surgical gown to adsorb a large amount of dust and bacteria to the wound of a patient, and simultaneously prevent the spark generated by the static electricity from detonating volatile gas in the operating room and influencing the accuracy of a precision instrument.
The physical and mechanical properties mainly refer to the capabilities of tearing resistance, puncture resistance, abrasion resistance and the like of the medical isolation suit material. The tearing and puncture prevention part provides a channel for the propagation of bacteria and viruses, and the wear resistance can prevent the floc falling part from providing a place for the propagation of the bacteria and the viruses.
At present, the fabric of the medical isolation protective clothing is generally made of a film-covered non-woven fabric material, such as a utility model patent with the patent number of 201620196440.3. The outer layer of the isolation clothes is a polyethylene film layer, and the inner layer is a non-woven fabric layer. The non-woven fabric has the characteristics of air permeability, flexibility, light weight, easy decomposition, low price and the like, but the tensile strength of the non-woven fabric is poor. The isolation protective clothing adopts a non-woven fabric form, is extremely easy to damage, does not basically have a protective effect, and can only block substances such as dust and the like. The PE (polyethylene) film is coated to improve the tensile strength of the non-woven fabric and improve the protection effect. PE film-coated non-woven fabrics generally adopt a film coating technology, and have the advantages of simple and mature process, high production speed, poor air permeability, hard hand feeling, poor comfort and high requirements on non-woven fabrics.
