Problems solved by technology

[0003] The production process of general polyester industrial yarn is mainly: melt (polymerization melt or chip → melting) → spinning assembly → cooling → winding and forming. Among them, in the spinning process, the equipment investment, spinning position distance Influenced by factors such as the length of hot rolls and product characteristics, the conventional method can only use five-roll spinning, the distribution of the drawing ratio is limited, and the contact time between the raw silk and the roll body is small. Therefore, the obtained after final treatment It is difficult to reduce the fiber dry heat shrinkage to a satisfactory range, and the evenness of the yarn due to stretching is also difficult to control

Abstract

The invention relates to a spinning device with seven pairs of rollers and a technology for producing terylene industrial yarns by adopting the same, and belongs to the technical field of production of terylene industrial yarns. The spinning device with the seven pairs of the rollers comprises a spinning component and seven pairs of the rollers arranged below the spinning component; each of the seven pairs of the rollers is composed of two rollers with the same center distance as 40-100 mm; the first pair of rollers is closest to the spinning component; the second pair of the rollers is located below the first pair of the rollers; the third pair of the rollers is located at the right side of the first and second pairs of the rollers; the fourth and fifth pairs of rollers are located at the right side of the third pair of the rollers. The spinning device with the seven pairs of the rollers can match with chip spinning and melt direct spinning respectively, the production way is flexible, and production of low-shrink terylene industrial yarns and common high-strength terylene industrial yarns can be realized through adjusting the roller speed, roller temperature and position setting of each pair of the rollers.

Description

technical field [0001] The invention relates to a seven-pair spinning device and a process for producing polyester industrial yarn by using the device, belonging to the technical field of polyester industrial yarn production. Background technique [0002] Polyester industrial yarn refers to high-strength, coarse-denier polyester industrial filament, and its fineness is not less than 550 dtex. According to its performance, it can be divided into high-strength and low-stretch type (ordinary standard type), high-modulus low-shrinkage type, high-strength low-shrinkage type, and active type. It is mainly used as tire cord fabric, safety belt, airbag, automobile seat belt, automobile transmission belt, fan belt and automobile rubber hose, etc., and the potential large amount is fastening belt, traction belt, automobile traction belt and automobile tarpaulin. [0003] The production process of general polyester industrial yarn is mainly: melt (polymerization melt or chip → melting...
