Non woven geotextile
1)Staple fibers needle punched non woven geotextile
The geotextile is made of polypropylene staple fibers on cross-laying equipment and needle punched equipment.
Feature: It owns the advantages of acid and alkali resistance, erosion resistance, aging resistance, large strength, stable size, good filtrability etc.
Functions: It mainly applied in water conservancy, road and railway for strengthening, separation, reversed filter and drainage of projects
2)Filament non woven geotextile
Filament geotextile has features as follows: High strength, good capacity of elongation and high biology tolerance, alkali tolerance, acidity tolerance, weather resistance good filtration and fine drainage capacity etc. Alo it is of low cost, easy in construction and use effects
Technical specification of shot fiber needle punched non woven geotextile:According to GB/T17638-1998 Standard
