What non-woven fabrics are commonly used in masks, will there be spun-bonded non-woven fabrics?
We all know that masks are made of non-woven fabrics, but when asked which specific non-woven fabrics, you may not necessarily know. The non-woven fabrics commonly used in masks generally include spunlace non-woven fabrics, melt-blown non-woven fabrics and spun-bonded non-woven fabrics. The different names of these non-woven fabrics are also named according to the process of non-woven fabrics.
Today, the editor of Lai Chi introduces spunbond non-woven fabrics.
Spunbond nonwoven fabrics, as the name implies, are first spun and then bonded into nonwoven fabrics, which are also spunlaid.
The technological principle of the production of spunbond nonwoven fabric: the spinneret of the spunbond nonwoven fabric is an ordinary spinneret. There is no high pressure spinning, and the filament is spun. After the filament is spun out, it is drawn by a high-speed air flow , Gather the fiber filaments after high speed drawing on the net curtain. Unlike melt-blown non-woven fabrics, which generally rely on the fibers to bond and consolidate before they are completely cooled, spun-bonded non-woven fabrics can bond and consolidate themselves before being completely cooled like melt-blown fabrics, or they can bind the fiber web Transported to the consolidation process to consolidate into cloth after spunlacing, hot rolling, etc.
Performance characteristics of spunbond nonwoven fabric:
The fibers in the spunbond nonwoven fabric are all filaments, and the fibers in the meltblown nonwoven fabric are not thin, and the fibers are not randomly arranged as in the meltblown nonwoven fabric. The fibers in the spunbond nonwoven fabric are directional. Therefore, the filtration efficiency of the spunbond nonwoven fabric is not as high as that of the meltblown fabric. It is generally used in the outer layer of the mask to filter large particles and waterproof. Spunbond and meltblown fabrics are generally made of polypropylene. This material is extremely hydrophilic, so it does not absorb water.
Well, about the relevant knowledge of spunbond nonwoven fabric, I will introduce it to everyone today.
