Nonwoven geotextile fabric is generally made of polyester or polypropylene filaments and short yarns, which are repeatedly interspersed and reinforced by multiple needle punching processes, and then processed by hot pressing. Nonwoven geotextile fabric products have high structural strength, low cost, good filtration, isolation, and maintenance, there are many kinds of specifications and models to choose from, and the role is also very wide, which is a common material for construction projects.
Geotextile nonwoven fabric, also known as geotextile, is a permeable geosynthetic material made of polyester or polypropylene fibers by needling or weaving. Short filament geotextile fabric is called polyester staple geotextile fabric, which is made of polyester curly staple fiber of 6 - 12 denier and 54 - 64mm in length. Through the non-woven equipment of opening, combing, messing, laying network, needle punching, and other production processes made of cloth-like.

Geotextile nonwoven fabric production approximate process flow: staple fiber raw materials - open loosening - carding - miscellaneous - laying net - needle punching - pressing and ironing - winding - slitting and packaging
Nonwoven geotextile filter fabric is mainly used in road construction, river embankment construction, landfill, river, and other construction projects, the main functions are:
It has an isolation effect: it can prevent the mixing or loss of 2 or more kinds of soil, maintain the overall structure and increase the foundation bearing.
There is a filtering effect: it can effectively block the particulate matter from falling through the performance of air and water, and increase the stability of the project.
It has a water-conducting effect, creating drainage channels in the soil layer and removing excess liquid and gas.
