| titleOfInvention | A kind of low resistance polyester negative pressure melt spinning manufacturing process |
| abstract | The present invention relates to a kind of low resistance polyester negative pressure melt spinning manufacturing process, polyester fondant first passes around slow cooling after low resistance spinneret orifice extrusion and forms as-spun fibre, then as-spun fibre carries out lost pressure cooling and natural cooling successively, low resistance spinneret orifice is the spinneret orifice for the low-surface-energy being surface-treated by polysiloxanes treatment fluid, spinneret orifice surface energy En≤35mJ/cm 2 , surface roughness Ra≤0.2 μm, surface static contact angle WCA >=85 °, lost pressure cooling refers to cooling in the constant temperature and pressure constant humidity enclosed environment that pressure is 0.001~0.01MPa, temperature is 5~105 DEG C of air atmospheres.The present invention effectively reduces the rheological resistance being subject to during melt flows and windage resistance, realize the full and uniform cooling of fiber, it has been obviously improved the spinning speed of melt spinning and the quality of fibre, has been applicable to the production and processing of the fibers such as thick denier, fine-denier, high strength and modulus. |
