Description
Technical Field
The invention relates to a novel material for protective clothing and a preparation method thereof, in particular to a novel material for protective clothing capable of being dissolved after moist heat sterilization and a preparation method thereof, and belongs to the technical field of material processing.
Background
The medical protective clothing is used for reducing the invasion of infectious substances such as viruses to medical workers in a working environment. Research on medical protective clothing has been developed in the developed countries, and the research on medical protective clothing in the united states is always at an advanced level in the world. In the period of second war, the army uses the superfine bimatous mercerized cotton to make the protective clothing with stronger water-proof performance, and after the second war is finished, it is used in the medical operation. 4 film materials of heterogeneous membrane, asymmetric membrane, homogeneous membrane and composite membrane and Gore fabric composite material developed in the United states in the 80 s of the 20 th century have good virus transmission resistance and good air permeability.
The medical protective clothing in China is valued and developed after the SARS virus Mat volume in 2003 in the whole country. Aiming at SARS infectious virus, the materials for manufacturing protective clothing in China are mainly common non-woven fabrics or rubber, etc., wherein the common non-woven fabrics have poor protective performance and can not reach the national protective standard; although the rubber has good protective performance, the air permeability is poor, and the rubber cannot be applied to medical working environments. After the combined efforts of science and technology workers, polypropylene spun-bond and melt-blown spun-bond composite material (SMS) non-woven fabric is developed, the SMS material not only has good antibacterial property and air permeability, but also can resist high hydrostatic pressure, and can adapt to various different environmental conditions through the technical treatment of the SMS material such as antibacterial, anti-aging, antistatic and the like, and high-grade surgical gowns made of the SMS non-woven fabric are widely applied at home and abroad; however, in the region with extremely strong infectivity, the SMS protection efficiency still can not meet the requirements, and further research is needed. Later, relevant scholars in China prepare the nylon-6/TiO 2 composite superfine fiber non-woven fabric by using an electrostatic filament device, and the antibacterial performance and the ultraviolet resistance of the protective clothing can be improved by applying the non-woven fabric to medical protective clothing. An antibacterial agent made of a chloramine compound has also been proposed as a protective layer of a protective mask to improve the bactericidal performance of the protective mask.
In 2019 to 2020, the novel coronavirus is rolled up around the world, relates to more than two hundred countries, has more infected people and wide range, is rare in human history, and has great influence on the health and economy of the global people. Medical protective articles become scarce materials, and medical protective clothing has important meaning in the aspect of infectious disease protection, especially for medical personnel, the material of protective clothing is vital, and medical personnel can be protected well in a special period, so that medical personnel are prevented from being infected in a large quantity, and the medical protective clothing has important meaning for prevention and control of epidemic situations.
At present, the protective clothing takes the renewal of materials as a core and develops to the aspects of high performance, multifunction, composite, health, comfort and the like. With the environmental requirements, the degradability is also an important aspect of research.
