Embodiment 1
[0018] Put the 30D / 10F or 20D / 7F POY raw yarn on the raw yarn rack, lead it out from the raw yarn rack, and pass through the first roller (also called feeding roller), hot box, cooling plate, false twisting Roller, second roller (also called traction roller), netter (select Haberly p203 model), auxiliary second roller, oiling device, winding roller, and obtain nylon 6 fine denier network elastic yarn after winding. Wherein, the distance between the auxiliary second roller and the second roller is 0.2 meters, the linear speed of the auxiliary second roller is less than the linear speed of the second roller, the draft ratio between the first roller and the second roller is 1.4, and the heating box The temperature is 145°C, the ratio of the linear speed of the friction disk of the false twister to the linear speed of the second roller is 1.8, the network pressure of the network device is 0.25Mpa, the linear speed of the first roller is 500m / min, the second roller The line speed i...
