The COVID-19 epidemic has been with us for more than two years. With the impact of the epidemic, masks have become more and more necessities in life. Masks can help us reduce the risk of being infected by the virus and protect us to a large extent during the epidemic. So how are the masks that have become our necessities and have a greater impact on our lives made? The Masks are made of non-woven fabrics, which are different from woven fabrics and are produced by non woven machines.
Non-woven fabric is a kind of fabric that does not require spinning or weaving. It is only formed by orienting or randomly arranging textile staple fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding or chemical methods.
Simply put: it is not interwoven and braided by yarns one by one, but the fibers are directly bonded together by physical methods, so when you get the sticky weight in your clothes , you will find that it is impossible to extract a single thread. Non-woven fabrics break through the traditional textile principles, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many sources of raw materials.
Features of spunbond non-woven fabrics: high strength, good high temperature resistance (can be used for a long time in 150 ℃ environment), aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, moth resistance, Nontoxic.
The most common and most commonly used non-woven bags are non-woven bags. The application level can also be used as flower packaging cloth, luggage cloth, etc., which are resistant to wear and tear. , the characteristics of firm feel and so on.
Meltblown fabric mainly uses polypropylene as the main raw material, and the fiber diameter can reach 1-5 microns. With many pores, fluffy structure and good wrinkle resistance, these ultra-fine fibers with unique capillary structure increase the number and surface area of fibers per unit area, so that the meltblown cloth has good filterability, shielding, heat insulation and oil absorption.
Available It is widely used in the fields of air, liquid filter materials, isolation materials, absorbent materials, mask materials, thermal insulation materials, oil absorbing materials and wiping cloths. Meltblown cloth filter material is randomly distributed and bonded together by polypropylene microfibers. The appearance is white, smooth and soft. The random distribution of fibers provides more thermal bonding between fibers. Therefore, the meltblown gas filter material has a larger specific surface area and higher porosity (≥75%). After being filtered by high pressure electret, the product has the characteristics of small resistance, high efficiency and large dust holding capacity.
A regular medical surgical mask consists of a three-layer structure, namely the SMS structure:
1. The inner spunbond layer is an ordinary spunbond fabric, which is mainly for moisture absorption;
2. The outer spunbond layer is a spunbond fabric with waterproof treatment, which is mainly used to isolate liquids and have the effect of preventing droplets.
3. The middle meltblown layer uses electret-treated meltblown cloth, which can filter suspended particles of bacteria and is the most important core layer.
