The raw material of the mask: non-woven fabric

Regarding masks, we only know that masks are difficult to buy, but we don't know why. The main reason is that the supply of raw materials exceeds demand. The shortage of raw materials has caused the price of masks to fluctuate again and again. So, how much do you know about non-woven fabrics and meltblown fabrics? The classification and function of non-woven fabrics of medical masks are explained in detail. First of all, we should know that the scientific name of non-woven fabric is non-woven fabric, so the standard of non-woven fabric is mostly named after non-woven fabric. The non-woven fabrics used in the production of masks are mostly polypropylene spunbonded non-woven fabrics, polyester non-woven fabrics and so on. With the outbreak of pneumonia caused by the new coronavirus infection, the demand for medical supplies in various places has surged, and there are mainly two main protective materials needed: one is medical protective clothing, the other is medical masks, and their main production materials It is non-woven fabric. Non-woven fabrics are also called non-woven fabrics and non-woven fabrics. Traditional fabrics, whether woven, knitted or other weaves, undergo fiber-spinning-weaving, and non-woven fabrics do not need to be spun, hence the name. The non-woven fabric has no warp and weft threads, it is very convenient to cut and sew, and it is light and easy to shape. Non-woven fabric breaks through the traditional textile principles, and has the characteristics of short process flow, fast production rate, high output, low cost, wide use, and multiple sources of raw materials. The main process of non-woven fabrics is fiber formation-consolidation-post-treatment. The types are mainly classified according to the method of consolidation and formation, mainly including spunbond, spunlace, dipping, needle punching, hot rolling, etc., and production The non-woven fabric in the mask is a spunlace non-woven fabric, which sprays a high-pressure fine water stream onto one or more layers of fiber nets to entangle the fibers with each other, so that the fiber nets can be reinforced and have a certain strength.
