Nylon Top Pin Method Can Greatly Improve The Quality Of Spinning
Nov 14, 2015

Top pin in spinning frame drafting part of important components, have a significant impact on yarn quality. In recent years, as the technology continues to improve and mature, some textile equipment companies to produce many new nylon top pin and PIN material and structure of technical breakthrough improvements were made. By being able to quickly and significantly improve the quality of yarn, the top pin favored by textile enterprises. But more domestic production of nylon top pin manufacturer, manufacturing and processing conditions and material limitations, there is a lot of product differentiation.


Spinning frame drafting top pin in the shape of twin-leaf-like. Through the springs on the top pin adjust jaw pressure, support apron NIP and PIN and roller drafting key fiber transmission distribution and evenness have certain relations. Their elastic JAWS section rubber ring on the support in the work place, and iron roller core with Bob up and down in a certain range, through the leaf spring elastic, jaws and apron surfaces at imposes some initial pressure, avoid plastic deformation in repeated up and down. In the process of drafting, jaw pin Rotary vibration absorbing rubber ring, stable rubber ring rotation speed to ensure the stable movement of the fiber.


While aprons at work can have some additional friction prevents fiber speed ahead, shortening the float zone length, stable and effective control of the short fiber movement, plastic ring extended NIP roller friction field forward, so as to improve the level of dry, reduce the number of kilometers nodules. Floating fibers in the drafting zone on yarn quality is obvious. If floating fibers out of control can lead to serious deterioration in evenness. So must ensure that the apron NIP a reasonable distance from the front roller NIP while making aprons middle and apron NIP pressure and stable to ensure steady improvement of spinning quality.
