In the 1960s and 1970s, the design of filament geotextile filter geotextile, a group that the decision to be protected several major soil hydraulic properties and fabric. Such as soil particle size and permeability of the fabric pore size, permeability, open area, such as c 7L where soil particle size and fabric 7L diameter plays a decisive role. People have made reference to the classical design principles pellets filtration through test analysis and proposed a different design criteria, in accordance with the characteristics of soil particle size aperture choice of fabric. About fabric aperture test method, used for the initial screening method or wet sieving. Since 1977 D. Yang M, Chen proposed to create dynamic water sieve method, in recent years has been used by many other countries. For fabric aperture design. Since the 1970s, not of the experts consider more factors: such as being protected soil particle size distribution, uneven degree of compactness, teaching, etc.; seepage flow state - laminar or turbulent flow; seepage direction - one-way or two-way, in line with the direction of gravity or opposite; openings of the fabric, the thickness of the structure, and the forces, and the like, made more complex design is pushed, and a long-term indoor test and prototype observation practical filament geotextile to verify the accuracy of these guidelines. But has yet to agree a recognized pattern. Permeable fabric is also pushing a similar situation. In view of the comments on the design criteria of divergence, thus filament geotextile Some experts suggested by the test to select fabric, namely the use of protected territories and fabric filter simulation test filament geotextile wholesale to determine if the fabric can meet the requirements of . Filament woven geotextile until now are using more filament woven and flat yarn woven, polypropylene-based materials. Filament geotextile and foundation, adobe, spewing rocks, mud or other foam cement using Edison filament geotextile together using mud from the filament geotextile for reinforcement, try to take care of, drainage, excessive leaching, isolation, anti seepage and other functions. Filament geotextile until now has been with Shimin Tu, steel and wood together are called the "four foam cement." The sum of the staff I sincerely companies to serve you expect your big head King speech:! Of geotextile fiber anti-aging properties Seminar:? On the research and production of new composite filament warp geotextile. New Materials Co., Ltd. Shandong Hongxiang you parse the production and application of filament geotextile rapid progress until now filament geotextile, many of the filament geotextile research, but relatively little about the filament geotextile aging seminar . New Materials Co., Ltd Shandong Edison filament geotextile progress aging performance and test standards cause seepage discussion concerned gaze, so progress to improve our business and complete. Filament geotextile based processing approach can distinguish clearly not the same as the filament woven geotextile fabric, knitted and nonwoven geotextile filament filament geotextile. American Society of Materials and try (ASTM) definition of filament geotextile is: everything and foundations, adobe, spewing rocks, mud, or whatever other material together using earth materials, and manufacturing engineering as artificial or system components local textiles. Because of this, to discuss filament geotextile aging properties with tall economic and strategic significance. Filament geotextile as an engineering material, its aging performance directly impacts the survival of life, safety and reliability.
