The dyeing grade is improved. The appearance grading index adds the content of the porous silk in the broken silk and the bobbin weight, and modifies the content of the broken silk, the oil stain, the trip silk and the like.
The current nylon 6 stretch yarn is convenient for texturing by increasing the elasticity through a twister and generating mechanical twisting stress, and a friction disc false twister is mainly used and is one of main parts for false twisting and texturing. The yarn passes through the middle of the three superposed friction disks, and the outer edge surface of the disk is directly rubbed with the surface of the yarn to be twisted. The three series of the stacking disks rotate in the same direction, and push the strand silk to rotate and advance together when rotating. The upper yarn section of the false twister is twisted, and the lower yarn section is untwisted into a textured yarn. The upper section of strand silk has a certain inclination angle and can enter the friction disc, and the strand silk and the friction disc are not positively held for twisting and have slippage, so that the circumferential speed of the strand silk is lower than that of the friction disc. The filament is also in axial output motion.
