Abstract
A half-slide matched device and its application for ultra-smoothly reconstructing yarn hairy structure belong to a textile processing field. According to the half-slide matched device of the present invention, a vortex device static part and a vortex device moving part are matched. In practice, multiple devices are connected in tandem. When yarn moves, the parts of half-slide matched device are closed, for efficiently constraining and utilizing the vortex airflow. A directional jet tube one-directionally stretches hairiness on yarn surface to avoid hairiness random dispersion and entanglement, remove yarn surface impurities. Tandem-connected devices repeatedly superimpose and strengthen the reconstructed ultra-smooth yarn structure. The half-slide matched device can be opened when the yarn breaks, which facilitates splicing and maintenance. The half-slide matched device has a reasonable structure and is very convenient for wide application.
