About woven geotextiles

• Geotextile:  Geotextiles are textile structures such as fabrics, mesh materials, nonwovens, nets, and composites, which are deployed in various areas of underground construction for separation, support, protection, filter and/or drainage functions.
• For nonwoven geotextiles, weaving technology is in the forefront, and now it is most widely used. Generally, wide looms with both creel & beam are used to manufacture the woven geotextiles. In this case, monofilament yarn, multifilament yarn, & tape are used.
• Woven geotextiles are preferred for applications where high strength and high modulus in the principal directions are more important considerations than similar properties in all other directions.

Difference between woven & nonwoven geotextiles:

Product characteristics

The desired characteristics of woven geotextiles are:

• Ability to resist clogging
• Excellent elongation at break
• Excellent permittivity of water
• Good grab tensile strength 
• Puncture resistance
• Trapezoidal tear strength
• U.V. resistance
• Very good Mullen burst

Application

Woven geotextiles are mainly used in

• Coastal works,
• Embankment and in or near dams
• Waterways, and
• woven geogrids for reinforcement

Raw materials

The main raw materials for woven geotextiles are monofilament or multifilament of 

• Polyester
• Polypropylene
• Jute
