1. On raw materials

Short-filament geotextile is usually made of polyester or polypropylene staple fiber by needle consolidation, and the same specification is slightly different from that of filament geotextile; The conventional filament geotextile is the filament spunbonded needle-punched nonwoven fabric made of polyester fiber. Compared with the staple geotextile, the strength, elongation, bursting and other parameters of the same specification are better than the staple geotextile.

2. Appearance

In terms of shape, the chemical fiber on the surface of the short filament geotextile is shorter, and the color is darker than that of the long filament geotextile; The filament geotextile and the short filament geotextile are very easy to distinguish. The surface chemical fiber of the filament geotextile is longer and the color is much whiter than that of the short filament geotextile.

3. Application

Short wire geotextile has very good mechanical properties, so it has certain applications in many engineering projects, such as construction engineering, civil engineering, greening engineering, etc; The filament geotextile is thick, can leave three-dimensional void ratio, and is conducive to some hydraulic performance; In addition, the puncture resistance of filament geotextile is better than that of polyester staple geotextile. The creep resistance of polyester filament geotextile with the same unit, area and quality is better than that of polyester staple geotextile.

Filament geotextile is a kind of geotextile with three-dimensional pores, which is made of PET chips as raw materials, and is produced by melt spinning, air flow netting, and re-punching consolidation process. Product specification: weight 100g/㎡ - 800g/㎡, material width 1-6m, conventional standard parts 6 * 50m in a roll. The filament geotextile has high mechanical index and good creep.

It has strong corrosion resistance, excellent aging resistance and heat resistance, can adapt to uneven base course, can resist external force damage during construction, and has small creep. It can still maintain its original function under long-term load. Even if it is exposed in the environment of nearly 20 ℃ for a short time, its performance has hardly changed. A large number of tests and practices have proved that the filament geotextile has long-term corrosion resistance to various natural soil, water and microorganisms.

Scope of application: mainly used for reinforcement, filtration, isolation and drainage of water conservancy and hydropower, environmental protection, highway, railway, embankment, coastal beach, metallurgical mine, landfill and other projects.
