Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of flame -retardant polyester yarn, especially a continuous drying device of flame -retardant polyester yarn. BACKGROUND

[0002] In the textile industry, polyester yarn as a common synthetic fiber material is widely used in various textile manufacturing due to its high strength, good wear resistance, strong elastic recovery ability and other characteristics. However, polyester yarn often needs to be dried in the processing process to remove the moisture on its surface or humidity to ensure the subsequent processing quality and product performance. Especially in the production of flame-retardant polyester yarn, drying treatment is an indispensable link because the flame-retardant performance is closely related to the dryness of the yarn.

[0003] Traditional polyester yarn drying devices mostly adopt intermittent drying mode, that is, the yarn is first placed in a certain length of drying chamber, and then the drying chamber is heated by a heating device to gradually dry the yarn. However, this drying mode has many shortcomings. First, the intermittent drying efficiency is low and cannot meet the needs of large-scale production. Second, due to the uneven distribution of temperature and humidity in the drying chamber, the yarn drying degree is often inconsistent, affecting product quality. In addition, the traditional drying device often needs to transfer the yarn multiple times during the drying process, increasing the labor intensity and production cost. SUMMARY
