Description

Technical Field

[0001] The utility model relates to the technical field of polyester yarn processing, in particular to a polyester yarn twisting device. Background Art

[0002] Polyester yarn is characterized by its ability to withstand chemicals and frequent washing, reducing fading and discoloration of clothing. Relatively speaking, polyester yarn is tougher than rayon. When one end of the spinning is held and the other end is rotated, yarn is formed. This process is called twisting. Twisting uses a rotary motion to twist the stretched thin strips, like twisting a towel when washing your face, to fix the longitudinal connections between the fibers.

[0003] In the existing technology, most of the current twisting work is processed by twisting equipment, but some twisting devices are not equipped with a structure to control the tension of the polyester yarn when in use. If the tension of the polyester yarn is too large or too small, it will cause differences in the strength, uniformity, color, etc. of the yarn, and inappropriate polyester yarn tension may cause unstable operation of the twisting equipment, thereby affecting production efficiency. At the same time, when a section of polyester yarn is twisted, the length is shortened due to the longitudinal connection between the fibers. When the structure that fixes the polyester yarn cannot be adjusted, it is easy to affect the processing work. Utility Model Content
