Followed by the successful application of polypropylene fiber in cement concrete works,polyester fiber is a kind of recently-developed new engineering material mainly applicable to the reinforcement of anti-cracking properties of asphalt concrete.By taking polyester as themain raw material, it is produced through the application of process listed as follows,the plasticization melting,extrusion,high speed filament injection,and high-rate tensile is followed by the special surface treatment process and cut-off by special cutting machine.The appearance of product is a mesh-shapd structure integrating with multiple pieces of fiber monofilament.
Polyester fiber is not only characterized by such merits as high fineness,high strength,and ease of dispersion in common polymer fiber,but also featured with pronounced high temperature resistance performance.For this regard,it can either be widely applied in hot mixing asphalt concrete works,or applied in the anti-cracking reinforcement of high strength concrete.In a word,it is considered as an ideal multi-functional reinforcement meterail.Tests conducted by several authoritative institutions around China indicated that the main thehnical performance indicators of polyester fiber produced by our company meet or exceed the advanced level of similar products abroad.
