Example Embodiment

[0018] Example 1: Heat treatment of the water ski rope. The water ski rope in this example is made of high-strength PP / high-strength synthetic fiber. The water ski rope made of the above-mentioned materials is heat-treated by electromagnetic heating. The tubular heater is installed between the rope production device and the rope collection device. In the meantime, the temperature of the heat treatment is controlled at 60℃, and the speed of the rope passing through the inner cavity of the tubular heater is controlled at 0.7m / s. Through the above heat treatment, the added tension to the rope during the process of chemical fiber spinning and rope production and processing can be effectively overcome, resulting in a tension difference between the fiber and the strand, and the performance of the chemical fiber cannot be maximized. At the same time, this method can effectively and quickly eliminate the uneven tension in the rope, so that the rope has a better appearance and feel, and...

Example Embodiment

[0019] Example 2: Heat treatment of climbing rope. The climbing rope in this case is made of nylon. The climbing rope made of the above-mentioned material using a production process with a spool of 48 strands is heat-treated by electromagnetic heating. The tubular heater is installed in the rope production device and the rope collection device. In between, the heat treatment temperature is controlled at 130°C, and the speed of the rope passing through the inner cavity of the tubular heater is controlled at 0.55m / s. Through the above heat treatment, the added tension to the rope during the process of chemical fiber spinning and rope production and processing can be effectively overcome, resulting in a tension difference between the fiber and the strand, and the performance of the chemical fiber cannot be maximized. At the same time, this method can also effectively and quickly eliminate the uneven tension in the rope, so that the rope has a better appearance and feel.

Example Embodiment

[0020] Example 3: Heat treatment of the traction rope. The material of the traction rope in this case is high-strength PE monofilament. The traction rope made of the above material is heat-treated by electromagnetic heating. The tubular heater is installed between the rope production device and the rope collection device. The temperature is controlled at 70℃, and the speed of the rope passing through the inner cavity of the tubular heater is controlled at 1.0m / s. Through the above heat treatment, the added tension to the rope during the process of chemical fiber spinning and rope production and processing can be effectively overcome, resulting in a tension difference between the fiber and the strand, and the performance of the chemical fiber cannot be maximized. At the same time, this method can also effectively and quickly eliminate the uneven tension in the rope, so that the rope has a better appearance and feel.

Abstract

The invention discloses a device and a method for chemical fiber rope heat-treatment, wherein the device comprises a tubular heater and a movable hollow sleeve. The method comprises the following steps: the hollow sleeve which is matched with a chemical fiber rope penetrates the tubular heater, the tubular heater is heated, and the chemical fiber rope passes through the inner chamber of the hollow sleeve at the speed of 0.1 to 2.0 m/s. In continuous production, the invention can carry out safe, controllable and efficient heat treatment to the chemical fiber rope and can eliminate the tension in fibers and plied yarns.

Description

technical field [0001] The invention belongs to the technical field of heat treatment, and in particular relates to a chemical fiber rope heat treatment device and method. Background technique [0002] With the popularization and development of high-level sports and leisure activities such as rock climbing and mountaineering, higher requirements have been put forward for the safety and comfort of the rope. The impact force of a fall with a coefficient of 1.77 can reach 20-40KN, so this requires the rope to have sufficient elongation during the impact process to extend the buffering effect of the rope on the impact force and reduce the impact of the rope on the human body force to protect the body from injury. In the conventional chemical fiber rope processing process, the strength problem is not difficult to solve, on the one hand, by adjusting the process, on the other hand, by improving the raw material, increasing the rope diameter, etc. However, these methods are not a...
