Since the reform and opening up, non-woven fabrics are the most emerging industry and have rapidly occupied the Chinese market. There are many types of non-woven fabrics, and imported dry-laid spunbond non-woven fabrics are one of them.
The main difference between the spunbond production process and chemical fiber spinning is the use of air drafting and direct web formation. Therefore, the drafting of the spunbond method has become a core technical issue. In the past, mechanical drafting was used , the fiber monofilament is thicker and the mesh is unevenly laid.
Spunbond production equipment in various countries around the world has adopted air drafting technology. Due to different air drafting methods, there are three different forms of spunbond production lines, namely tubular drafting, wide slit drafting, and narrow slit drafting. Stretching etc.
Imported dry-laid spunbond non-woven fabrics have good heat resistance, with a melting point of 164~170°C, and the products can be sterilized at temperatures above 100°C.
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.
