Surface Modification of Ring-Traveler of Textile Spinning Machine for Substantiality

Abstract

In this report, a study of the wear mechanisms involved in spinning Ring and Traveler of textile industry have been presented. These components, after surface processing with various coatings techniques, were analyzed on the test rig to analyze the wear mechanism. The objective was accomplished by comparing various plasma sprayed coatings on E52100 steel pins using a Pin-on-Disc machine. The surface morphology as well as mechanical properties of the deposited coatings namely WC-Co-Cr, Al2O3+TiO2 (Alumina-Titania) and Cr3C2NiCr, as well as uncoated E52100, were comparatively studied. This study elucidates towards improving the working life of the Ring in a Textile mill while spinning operation. An X-ray diffractometer (XRD) and Scanning Electron Microscope (SEM) was employed to characterize the unworn and worn surfaces of the specimens. The study revealed that the wear rate of Plasma sprayed thermal coatings enhanced with augmenting load. The Plasma sprayed WC-Co-Cr, Cr3C2NiCr, Al2O3+13TiO2 coatings developed on workpiece pins exhibited a notable decrease in volume loss of the material as compared to uncoated E52100 substrate. WC-Co-Cr coating turned out to be the best performer in terms of lowest cumulative volume loss among all the variants of coatings.

Intelligent Nanomaterials for Solar Energy Harvesting: From Polar Bear Hairs to Unsmooth Nanofiber Fabrication

“…Nano-scale surface morphology greatly affects a surface’s chemistry property ( Marmur, 2004 ; Li X.-X. et al, 2021 ), friction property ( Cao et al, 2021 ; Bains et al, 2020 ), and reflection property ( Selkowitz 2021 ). According to the geometric potential theory ( Peng and He, 2020 ; Han and He, 2021 ), a nano-scale surface can produce high geometric potential.…”

Dry Sliding Friction and Wear of the Wc/Tic-Co in Contact With Al2o3 for Two Sliding Speeds

“…The test process involving the Al2O3 ball and the two cermets (WC/TiC-Co) and the reference (WC-Co) samples have undergone friction and rotary sliding tests at a high temperature using a tribometer (CSM Instruments Switzerland) (Fig. 4) [20]. The four considered cermets have experienced tests, at two speeds (Table 4), using a 6 mm diameter alumina ball with hardness (HV) and density values of 1800 and 3.2, respectively.…”

Comparing Performance of 3D-Printed and Injection-Molded Fiber-Reinforced Composite Parts in Ring-Spinning Traveler Application

“…The working life of both the ring and traveler largely depend on their surface characteristics, which also affect the yarn properties (i.e., hairiness). The smoother the surface is, the lower the friction, and the longer the life of the dynamic component and the yarn quality [22,26]. Consequently, some researchers attempt the surface modification of both ring and traveler to improve wear resistance [26].…”

“…The smoother the surface is, the lower the friction, and the longer the life of the dynamic component and the yarn quality [22,26]. Consequently, some researchers attempt the surface modification of both ring and traveler to improve wear resistance [26]. Figure 1 presents the images of the traveler that show that 3D-printed parts have poor surface properties compared to the molded ones.…”
