specific Embodiment 1
[0018] Specific embodiment 1 of the present invention: the one-step production process of this ultra-coarse denier polyester industrial fiber, comprises the following steps:
[0019] A. Spinning and oiling: After the polyester chip is melted, it is slowly cooled by a slow cooler with a temperature of 300-400 ° C, and the side blowing is cooled in the spinning box 1 through 8-12 ends of the spinning assembly 2, and then Use spinning oil to oil through two sets of oiling components in sequence. Each set of oiling components is equipped with an oil pump. The specification of the oil pump for the first set of oiling components is 0.05-0.10CC, and the speed is 33-53rpm; The specification of the oil pump equipped with the oiling assembly is 0.05-0.10CC, and the rotation speed is 12-32rpm. Among them, the melted polyester chips are metered by the metering pump. The specification of the metering pump is 50CC, and the rotation speed is 14.95±0.2-16.5±0.2rpm ;

Abstract
The invention discloses a one-step production process for ultra-coarse denier polyester industrial fibers. The one-step production process comprises the following steps: A. spinning yarn oiling: the polyester chips are subjected to the 8-ends to 16-ends spinning by a spinning assembly in a spinning box and then oiled by two sets of oiling assemblies in sequence; B. drawing and heat-setting: the yarn strands are treated by pre-tension rollers and then drawn by three groups of drawing rollers in a pre-netting machine, and finally each is heat-set by a group of setting hot-rollers and subsequently jointed to be treated by the pre-netting machine; and C. winding formation: the yarn strands go from a main netting machine to a winding machine and are wound and formed by a winding head inside the winding machine, to obtain the final product. The one-step production process can produce ultra-coarse denier polyester industrial fibers (from 5000D to 7000D) with reasonable selection of process parameters, reasonable equipment configuration and low production cost, and can ensure excellent even better physical property of the ultra-coarse denier polyester industrial fibers.
Description
technical field [0001] The invention relates to a one-step production process of ultra-coarse denier polyester industrial fibers, belonging to the technical field of polyester industrial fibers. Background technique [0002] For a long time, the raw materials used in the industrial sling and geotextile industry have been traditional natural fibers and metal materials, but the physical and chemical properties of natural fibers and metal materials are far from satisfactory when used as industrial slings and geotextile materials. The actual demand of this type of product greatly affects the service life of the product and the safety factor of work. With the advancement of production technology in the synthetic fiber industry and the rise of industrial production, nylon and polyester have rapidly become the main raw materials for industrial textiles. Polyester industrial fibers are widely used in industrial slings and geotextiles because of their excellent physical and chemical ...
