The ideal medical protective suit should be multifunctional, not only able to protect medical staff from toxic and harmful liquids, gases or infectious viruses and microorganisms, but also comfortable to wear, with barrier properties, but also breathable, antibacterial and anti-allergenic, not harmful to human health. In addition, the choice of protective suit fabrics should also consider the cost and environmental protection after waste. Expand the full text The reusable protective suit needs to be washed and disinfected after each use, which is inconvenient to operate, greatly limits its weaving structure, and its protective performance decreases after a period of use. In view of this, protective suit made of disposable non-woven (non-woven) materials are gradually used in the world. This kind of protective suit, after further anti-bacterial, anti-static and other treatments, has similar hand feeling and performance with traditional textiles, and its price is lower. Therefore,Medical Disposable Coverall, it is widely used in isolation clothing and protective suit in the medical field. At present, the three major fibers used in the production of non-woven fabrics in China are polypropylene, polyester and viscose fibers. Polypropylene accounts for the highest proportion, accounting for 62%. Generally speaking, polypropylene used in the production of non-woven fabrics mainly refers to high melt index polypropylene fiber materials. In recent years, the demand for polypropylene high melt index fiber materials has been affected by multiple favorable factors and is favored by the market. Manufacturing enterprises are also actively developing and expanding the polypropylene fiber market. Statistics show that the domestic output of polypropylene fiber in 2019 is about 1.7 million tons, an increase of 7.5% over 2018. Among them, the high melting index polypropylene fiber material is 950,000 tons, with a year-on-year increase of 15.8%; the medium melting index polypropylene fiber material 770000 tons, basically flat. Non-woven production processes mainly include spunbonding, spunlacing, flash evaporation, SMS composite materials and so on. Spunbonded non-woven fabrics mainly use chemical fiber spinning method to form polypropylene filament, and then use airflow or mechanical method to separate the filament into a web, which is very close to the traditional textiles in terms of hand feeling and performance; spunlaced non-woven fabrics The flash evaporation non-woven fabric is formed by spraying fiber webs of fibers such as terylene, nylon, polypropylene and the like through a high-pressure water column and high-speed water flow to enable the fibers in the fiber webs to move, rearrange and mutually knot so as to achieve the aim of solidifying the fibers into cloth. Polyolefin is used as the main raw material, and electrostatic devillication is adopted, so that the filaments rub against each other in the drawing process to form electrostatic devillication, which repel each other and maintain a single fiber state, and then the fibers are condensed into a web by an electrostatic device, and the web is formed by hot rolling; SMS composite non-woven fabric is a kind of non-woven fabric made by combining two or more non-woven webs with different properties through chemical, thermal or mechanical means, Medical Full Body Coverall ,Full Body Disposable Coverall, or by combining different web forming processes. At present, disposable protective suit are mostly made of composite non-woven fabrics made of polyethylene breathable films. Polyethylene breathable film was prepared by blending LDPE/LLDPE resin carrier with about 50% special calcium carbonate, extruding into film, and then directionally stretching to a certain ratio. How does the industry leader cope with the ever-changing market demand? The "2020 Medical Nonwovens Innovative Materials and Intelligent Solutions Forum" hosted by Lingao Consulting with the theme of "Green, Innovation and Development" will be held in Changzhou on June 19, 2020. The conference will discuss the innovative application and sustainable development of medical non-woven fabrics from the perspectives of macro-market situation, development direction and technological innovation. Promote the exchange of key contents such as green development, intelligent manufacturing, energy saving, environmental protection,3 Ply Disposable Protective Face Mask, cost reduction and efficiency enhancement of non-woven industry.
