With the increase of PVA content in geotextile, the dry strength and wet strength of mixed geotextile have been greatly improved. The dry/wet breaking strength of pure polypropylene geotextile is 17.2 and 13.5kN/m respectively. Influence of short fiber content of 400g/m2 geotextile on dry and wet state
When PVA content is 60%, the dry/wet breaking strength of geotextile is up to 29 7、34. 8kN/m。 On the one hand, the high modulus and high strength polyvinyl alcohol has high strength and is not easy to break under the action of external force, and the acupuncture mixed with PP staple fiber can play a strengthening role; On the other hand, the linear density of polypropylene staple fiber in general geotextile is 6.7 dtex, while the linear density of high modulus and high strength PVA is 2.2 dtex.
Influence of short fiber content of 400g/m2 geotextile on dry and wet state
In the geotextile, there are a large number of high modulus and high strength polyvinyl alcohol fibers, whose linear density is small, which makes them tightly intertwined, thus improving the mechanical properties of the geotextile.
