Problems solved by technology

However, since Nisshinbo's production process is batch polymerization, the spinning speed is relatively low due to the limitation of the concentration of the stock solution
Since 2000, my country has introduced Nisshinbo dry spinning production technology from Japan. At present, there are four domestic manufacturers, except for a few manufacturers who have tried to increase the speed of 40D / 3F varieties (spinning speed increased from 530m / min. To 700m / min), the traditional Nisshinbo production process is generally still used, and there is no breakthrough in the speed increase of fine denier yarns below 30D / 3F (including 30D / 3F)

Abstract

The invention relates to a spandex winding process for increasing the speed of Nisshinbo's dry spinning fine denier yarn. The rotational speed of the first roller is 650-700m / min, the rotational speed of the second roller is 700-750m / min, and the rotational speed of the oiling roller is 5-15rpm, the friction roller speed is 700-750m / min, the winding machine traverse amplitude curve parameters are acceleration time 0-12s, width variable 0-20%, deceleration time 0-12s, winding angle 8.5-13.5° . The present invention overcomes the bad shape of the spandex yarn after the speed is increased by adjusting the roller speed of the winding equipment, the speed of the oiling roller, the speed of the friction roller and other parameters, correcting the parameters of the traverse amplitude curve of the winding machine, and adjusting the winding angle. technical difficulties, and the entire spandex winding process is simple to operate and easy to control.

Description

technical field [0001] The invention relates to a spandex winding process, in particular to a spandex winding process for increasing the speed of Nisshinbo dry spinning fine denier yarn. Background technique [0002] The Japanese Nisshinbo dry spinning production technology introduced by our company is at the leading level in the field of transferable technology in the world. The spandex yarn produced by it has good heat resistance, large elongation and stable silk quality, and has been well received by users. generally recognized. However, since Nisshinbo's production process is batch polymerization, the spinning speed is relatively low due to the limitation of the concentration of the stock solution. Since 2000, my country has introduced Nisshinbo dry spinning production technology from Japan. At present, there are four domestic manufacturers, except for a few manufacturers who have tried to increase the speed of 40D / 3F varieties (spinning speed increased from 530m / min. T...
