1. The structure and properties of polyester filaments are closely related to the filament velocity achieved in the spinning process. A stable structure with sufficient crystallinity and high molecularorientation requires the filaments spun at velocity around 4,500 m/min or higher. 2. Properties of light weight polyester spunbond fabrics depend strongly on the structure of the filaments, therefore are also closely related to the filament velocity. A strong, soft and dimension stableproduct can be produced with the filaments spun at velocity 4,500 m/min or higher. 3. Ason spunbond technology differs greatly from any other conventional technology in its unique spinning technique. A short spin line and a short draw slot are used so that a process is created wherein a maximum draw force F(z) and a minimum air drag F_(drag) under equivalent conditions are obtained, resulting in filaments being spun with a maximized inertial force F_(inert) at an elevated temperature. 4. High quality polyester light weight spunbond products can be produced with Ason spunbond technology. The production capacity is in a range of from 80 kg/h/m for 0.4 dpf products to 300 kg/h/mfor 2 dpf products.

Ason纺粘技术与众不同，其独特的纺纱技术与其他任何传统技术都不一样。使用短的纺丝线和短的拉伸槽，从而形成一种工艺，其中在相同条件下获得最大拉伸力F（z）和最小空气阻力F_（drag），从而使长丝以最大惯性旋转高温下的力F_（惰性）。 4.可以使用Ason纺粘技术生产高质量的聚酯轻质纺粘产品。生产能力范围从0.4 dpf产品的80 kg / h / m到2 dpf产品的300 kg / h / m。
