1. Chemical modification of polyester POY spinning. The so-called chemical modification technology refers to the use of meta-acid in the polymerization process or the addition of the third component, polymerization to obtain low crystallization rate of chemical modified polyester, high-speed spinning line fiber orientation and crystallization development is reduced. The purpose of chemical modification is to reduce the molecular weight of molecules and molecules between the molecular chain, so the need for greater stress to get the same degree of crystallinity, which is the first attempt to high-speed spinning POY silk used in a method.

2. Physical modification of polyester POY spinning. The so-called physical modification technology refers to the use of conventional polyester raw materials, through the process of improvement and mixing additives and other methods to achieve the purpose of improving the speed of polyester POY spinning, in which the role of additives and additives and polyester blends with the dispersion close relationship. An additive is added to the melt spinning to add the additive to the polymer melt.

3. Polyester POY spinning changes the melt spinning process. The method is based on the fact that 70% of the spinning stress in the high speed spun process comes from the air resistance and significantly reduces the air between the filament and the side blowing (quench air) by accelerating the side blowing to parallel with the spinning tow friction. Compared with the current side of the blowing process (side of the hair gently around the new filament) compared to the new process using the quenching gas along the axis of the beam blowing, and ultimately speed up the tow in the direction of the spinning speed.

Fubon Machinery Polyester POY spinning machine uses the most advanced technology, can maximize the spinning speed.
