Nonwoven, woven, warp (nonwoven equipment) three geotextile process difference

Geotextile is a textiles, which includes non-woven geotextiles, woven geotextiles and geotextile composite warp。 These three geotextile due to different production process and have different characteristics。 Nonwoven geotextile good adhesion, good performance and stable woven geotextiles, warp knitting compound geotextile strong tear resistance。 Non-woven geotextile: non-woven geotextile is a filament or staple fibers through the various equipment and process layout of a net, after acupuncture and other processes so that different fibers intertwined, entangled fixing the fabric normalized , so that the fabric is soft, plump, thick, stiff, in order to achieve different thickness to meet the requirements of non-woven geotextile fabric with good clearance from a very good adhesion, the fiber has a soft tear can seepage membrane deformation force also has good ability to adapt, but also has good surface drainage capacity, soft surface multi-gap has a good coefficient of friction can increase the adhesion of soil particles, etc。, can be prevented by preventing the loss of fine particles of particulate matter at the same time ruled out excess water, soft surface with good protection。 In accordance with the length of wire into a nonwoven geotextile filament or staple fiber nonwoven geotextile。 They can play a very good filtering, isolation, reinforcement, protection, etc。 It is a widely used geosynthetics。 Filaments tensile strength greater than a short wire, can be selected according to specific requirements。 Woven geotextiles (reinforcement geotextiles): woven geotextiles are composed of at least two sets of parallel yarns (or flat yarn) composed of a group along a vertical loom (fabric direction of travel), said warp, another group lateral arrangement called the weft。 Different weaving preparation equipment and processes will warp and weft interwoven woven into a cloth-like, can be woven into different thickness and density of depending on the scope of use, generally woven geotextiles thinner aspect to have a very strong anti tensile strength (greater than longitude and latitude), with good stability。 Woven geotextiles depending on weaving and use of latitude and longitude into reinforced geotextile geotextiles and non-reinforced two categories, reinforced geotextile warp tensile strength far greater than ordinary geotextiles。 Reinforced woven geotextiles general practice and geotechnical engineering projects increased, the main function is to enhance the reinforcement, has a planar isolation and protection functions, it does not have the plane drainage function can be selected depending on the purpose of use。 Composite geotextile warp: warp geotextile is a glass fiber composite (or synthetic) as a reinforcing material, with the staple acupuncture non-woven geotextile composite made of new material。 Warp knitting compound geotextile Unlike woven。 Its biggest feature is the intersection of warp and weft bend, each in a flat state。 Tie the two lines tightly and evenly fully synchronized external force, stress distribution, and when the applied force tearing the instantaneous, yarn along rip pro set to increase tear strength。 When warp composite, namely the use of warp bundled line between the weft and acupuncture staple fiber geotextile layer repeatedly walk through that became one of the three series。 Thus warp composite geotextile has the characteristics of both high tensile strength, low elongation, and both acupuncture nonwovens performance。 Therefore, warp knitting compound geotextile is a reinforcement that can be used to enhance the isolation protection, and has a three-dimensional level and to have a better overall method of poly water, different water effects。 Its solid matrix and pores showed a continuous phase, become porous filter effect is a versatile geotextile composites。 It is a high-level international base today geotextile composite applications。
