According to a national bio-based materials and degradation Dot print fabrics,non-woven products Standardization Technical Committee, deputy director of Beijing Technology and Business University, Professor Xu Guozhi introduced the world's industrial production have been or are in the industrialization phase of the bio-degradable plastics are mainly poly-lactic acid, polyhydroxyalkanoates, poly already lactone, poly-methyl ethylene carbonate, poly butylene succinate on the acid - butanediol - adipic acid copolyester, polyvinyl alcohol and polyethylene glycol. At present, the domestic bio-degradable plastics mainly used in plastic bags, non-woven bags,coverall shoe, Garbage Bag with Draw Cord, Garbage bag with draw tape，nonwoven shopping bags，fresh produce packaging and plastic sheeting and other fields.

Geotextile can be divided into woven geotextiles and

In our country since the "Ninth Five-Year" plan began to add large-scale infrastructure construction, airports, highways, railways, Dot print fabrics,non-woven products,non-woven bags,coverall shoe, Garbage Bag with Draw Cord, Garbage bag with draw tape，nonwoven shopping bags，non-woven products manufacturer, ports, rivers, comprehensive development, cross-sea engineering, estuaries and coastal revetment, marine development, marine aquaculture and so on requires a lot of geosynthetic materials; In addition, environmental issues, waste management, landfill, are equally right geosynthetics greater demand. Therefore, non-woven geosynthetic material anywhere in the world and in our country's future will have broad prospects for development.

In the filament is mainly polypropylene and polyester filament yarn needle geotextile, hot melt adhesive and hot rolling geotextile geotextile fabric, filament needle geotextile is mainly used for drainage, filtration, reinforcement and so on, which, polypropylene filament needle geotextile poor performance due to weather-resistant, not suitable for exposure to sunlight and air use; staple products of the scope and filament similar difference is that the mechanical strength of filament products is higher than short - fiber products, staple products, but a flexible process changes, application of fiber types is not limited to polypropylene and polyester, can be chosen at random according to actual needs.

Non-woven products manufacturer geotextile composite membrane is flexible non-woven fabric with the polymer composite membrane material made of composite materials with non-woven geotextile is usually in the 300-400 Quantitative grams / square meter between the thickness (3mm or so. Non-woven Geo-composite membranes used in the construction of the specification is 500-800 g / m², of which film thickness 0.2-0.8mm; non-woven substrate specifications for 100-300 g / m².

Non-woven products geosynthetics role: a dispersed base stress, improve the foundation bearing capacity; 2 reduces the lateral deformation of the foundation, regulate non-uniform settlement, to reduce the total settlement amount; 3 increase in the foundation of shear capacity, thereby improving the stability sex (that is, consolidation of foundation); 4 the formation of directional horizontal drainage surface, since hydraulic conductivity, drainage effect; 5 isolators to improve the construction conditions, improve project quality, to extend the project life; 6 to facilitate placement and reduce total project cost.
