According to the definition of [textiles, nonwovens terms], nonwovens are directional or randomly arranged Sheets, webs or mats made of fibers that are combined with each other through friction, cohesion or adhesion, or a combination of these methods. There are many types, and pet spunbond polyester non-woven fabric is one of them.
Both spunbond and meltblown are non-woven fabrics (non-woven fabrics), which are widely used in the production of protective clothing and masks. The surface spunbond material has a waterproof effect; the middle meltblown material plays a core protective role. , can effectively prevent the penetration of bacteria, viruses and other tiny particles; the inner layer of spunbond material directly contacts the skin, and together with the surface layer plays a role in shaping and protecting the middle layer.
Pet spunbond polyester non-woven fabric has good heat resistance, with a melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃. It will not deform at 150℃ without being affected by external force. The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE. It also has good chemical stability. In addition to being corroded by acids, it is relatively stable to various other chemical reagents. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can soften and swell non-woven fabrics. The chemical stability varies with the degree of crystallinity. The increase has also improved.
