Polyester fiber drying device and drying process

Abstract

The invention relates to the technical field of polyester fibers, and discloses a polyester fiber drying device and a drying process, the polyester fiber drying device comprises a box body, an air heater is fixedly installed on the top of one side of the box body, the output end of the air heater is fixedly connected with an air supply pipe, and a flow dividing pipe is installed on the surface of the air supply pipe. According to the polyester fiber drying device and the drying process, through the arrangement of the hot-air blower, the air supply pipe, the flow dividing pipe, the partition plate, the preheating cavity, the suction ventilator, the filtering cavity and other structures, the hot-air blower is started to feed hot air into the flow dividing barrel, and the temperature of the hot air can be kept stable in cooperation with a heating rod in the flow dividing barrel; the phenomenon that the drying effect of the polyester fiber cloth is affected due to heat loss in the air transfer process is avoided, the polyester fiber cloth on the heat conduction barrel can be preliminarily dried through the heat conduction barrel with the temperature, hot air blown into the flow dividing barrel can flow outwards to make contact with a backflow cover when encountering the inner wall of the flow dividing barrel, the hot air is blown to the outer surface of the polyester fiber cloth, and therefore the drying effect of the polyester fiber cloth is improved. And secondary drying can also be carried out.

Description

technical field [0001] The invention relates to the technical field of polyester fibers, in particular to a polyester fiber drying device and a drying process. Background technique [0002] Polyester fiber has the advantages of high modulus, high strength, high elasticity, good shape retention and heat resistance, and has become the most widely used and most consumed fiber variety. It has the phenomenon of melting and dripping, which is easy to cause secondary harm, which greatly limits its use. Therefore, the research and application development of polyester fibers in various countries in the world are becoming more and more active. Various polyester fiber varieties are constantly coming out. Drop modification is mainly achieved by adding anti-dropping agents (such as polytetrafluoroethylene powder and melamine cyanurate), layered silicate to improve the structure of the combustion charcoal layer, or through the post-finishing of fiber fabrics to achieve the purpose of modi...

[0002] Polyester fiber has the advantages of high modulus, high strength, high elasticity, good shape retention and heat resistance, and has become the most widely used and most consumed fiber variety. It has the phenomenon of melting and dripping, which is easy to cause secondary harm, which greatly limits its use. Therefore, the research and application development of polyester fibers in various countries in the world are becoming more and more active. Various polyester fiber varieties are constantly coming out. Drop modification is mainly achieved by adding anti-dropping agents (such as polytetrafluoroethylene powder and melamine cyanurate), layered silicate to improve the structure of the combustion charcoal layer, or through the post-finishing of fiber fabrics to achieve the purpose of modification.

[0003] Polyester fiber will go through many steps in the production process, including the drying process, while the traditional drying process has low drying efficiency when drying it, which is easy to cause heat waste, resulting in energy consumption. waste, so a polyester fiber drying device and drying process are proposed
