长丝聚酯胎基布

长丝聚酯胎基布采用优质的聚酯切片，通过纺粘直接成网、针刺固结、高温定型、浸胶、烘燥等一系列工艺加工而成。纺丝熔体经高速气流拉伸，在高喷头拉伸的作用下，使形成的长丝纤维具有较高的取向度、结晶度及结构稳定性，并赋予其较高的拉伸强力和较大的剩余拉伸率。因此长丝聚酯布具有较强的拉伸强力、撕裂强力、顶破强力、延伸率及热稳定性。是迄今为止国际公认的性能最佳的改性沥青防水卷材胎体，主要应用于房屋建筑、高速铁路、高速公路、机场、港口码头、水利设施等领域。
Filament fiber Polyester mat is made of high quality PET chips, which are processed by spunbonding directly into the net, needle punching consolidation, high temperature setting, dipping glue, drying and other processes. The spinning melt is stretched by high-speed airflow under the action of high nozzle stretching. it makes the formed long fibers has a high degree of orientation, crystallinity and structural stability, and imparted with high tensile strength and large residual elongation. Therefore, the filament fiber polyester mat has strong tensile strength, tearing strength, bursting strength, elongation and thermal stability.It is the best internationally recognized foundation for the modified bitumen waterproof membrane which mainly used in house construction, highways, airports, port terminals, water conservancy facilities and other fields.
