In today’s era, with the growth of the economy, people’s demand for non-woven fabrics is increasing, which includes imported spunbond filament non-woven fabrics. Let’s take a look at it below.
The production process of melt-blown nonwoven fabrics is to use polymer slices with high melt index (MFI for short), which are heated by extrusion and melted into a high-temperature melt with good flow properties, and then use high-temperature and high-speed hot air flow. A production process in which the thin stream of melt ejected from the spinneret is blown into very fine fibers, which are gathered into a fiber web on a receiving device (such as a web-forming machine), and are bonded to each other using their own waste heat to form cloth.
Imported spunbond filament 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. Chemical stability It also improves with the increase of crystallinity.
