Abstract
The utility model relates to a device for preparing terylene curly threads, especially to a spinning device for preparing fibers with a potential curling function. The device is formed by additionally equipping heaters on the outer sides of spinning components on the basis of a piece of conventional FDY production equipment. Each heater comprises heating coils, a temperature sensor and a temperature controller. The temperature sensor is placed on the heating coils. The output end of the temperature sensor is connected with the temperature controller. The heating coils which are tightly attached on the periphery of a spinning component pressure plate are connected through fixing bolts. The heating coils are controlled by the temperature controller to heat. The device ensures the viscosity of spinning melt bodies and meanwhile makes the melt bodies in a high-temperature state the instant the melt bodies are squeezed out from spinneret holes. Thread bundles are benefited to have transverse crystallization differences during a side-blowing cooling process. Products are made to form different orientation degrees and crystallization degrees before being molded. Potential curly thread products are then obtained. By adopting the device provided in the utility model, the temperature of a whole system can be reduced by approximately 5 degrees during a spinning process. The energy consumption is thus reduced. The production cost is lowered.
