Problems solved by technology
The filaments obtained by this process are uniform and fully drawn non-elastic filaments, and special effects such as slub filaments cannot be obtained.
In addition, due to the high spinning speed and high draw ratio of the existing FDY process, there are relatively many wool and broken ends

Embodiment
[0009] Embodiment: The one-step stretching method of the present invention prepares 167dt / 37F "snowflake-like" slub polyester filaments. Using super-bright polyester chips as raw material, using a three-lobed special-shaped spinneret to spin, and spinning in FDY spinning equipment, the spinning speed is 3150m / min, the speed of the drawing roller is 1440m / min, and the temperature of the drawing roller is 70°C. Wind the wire 2 times on the stretching roller, and wind the wire 6 times on the shaping roller (same as the original), the speed of the shaping roller is 2980m / min, the temperature of the shaping roller is 112°C, the stretching ratio is 2.1 times, the pre-network pressure is 0.22MPa, cool The wind speed is 0.62m / s, and the wind temperature is 24°C. The main network pressure is 0.3MPa, and the cylinder weight is 7kg / piece.

Abstract
The invention discloses an FDY dacron bamboo joint filament with glossiness. The cross section of the FDY dacron bamboo joint filament is in a three-leaf special shape. The FDY dacron bamboo joint filament is characterized in that the filament is an FDY, the stretching degree is in the range of 80+ / -50%, the strength is 2.4-3.5CN / dt, the network degree is in the range of 15+ / -5 pieces per meter, and the boiling water shrinkage is in the range of 32+ / -6%. The preparing method for the FDY dacron bamboo joint filament comprises the steps that filament spraying is carried out on a dacron slice through a three-leaf special-shaped spinneret plate, stretching and forming are carried out, and the process of stretching and forming is characterized in that the stretching speed ranges from 2800m / min to 3200m / min, the pre-network stretching pressure is 0.22Mpa, the stretching multiple ranges from 1.9 to 2.2, the hot roller speed GR1 ranges from 1400m / min to 1600m / min, the hot roller speed GR2 ranges from 2800m / min to 3200m / min, the hot roller temperature GR1 ranges from 65 DEG C to 75 DGE C, and the hot roller temperature ranges from 108 DEG C to 118DEG C.
Description
technical field [0001] The invention is an improvement to FDY polyester filaments for home textile fabrics, in particular to a glossy FDY polyester slub filament and a preparation method. Background technique [0002] Functional textile varieties are constantly coming out, such as sofa releases, curtain fabrics, decorative fabrics and other home textile fabrics. The filaments used in such fabrics require good dyeability, bright color, good luster, good drape, and individual style. [0003] Polyester FDY spinning process uses semi-dull or glossy polyester slices as raw materials, and the filaments are sprayed out through a circular hole spinneret, and then stretched uniformly by the differential speed of the drafting roller and the setting roller. The temperature of the drafting roller is usually 90- 95°C, roll speed 1800-2300 m / min, sizing roll temperature is usually 130-145°C, roll speed 4500-4900 m / min, and then through the main network to increase the cohesion of the wire...
