Dimensional tolerances shall comply with the textile industry standards for yarn tubes.
The tube surface shall be smooth with uniform color, free from pores, delamination, obvious scorching, or impurities. The grooves shall be clear, without burrs or sharp edges.
When mounted on a standard spindle and rotated at 1,400 rpm, the vibration amplitude shall be <0.2 mm.
The specially treated flocking shall be directional: when the tube rotates counterclockwise, it shall not adhere to the roving; adhesion shall only occur during clockwise rotation.
Suitable for textile processes involving cotton, linen, wool, and synthetic fibers. The spools come in various designs such as colored head type, zigzag slanted groove, arc-shaped groove, and offer a wide range of colors for customers to choose from.
The bobbin tube is a specialized tubular equipment used in the textile industry for winding coarse yarn (unfully twisted fiber strips). It is usually made of wood, paper or engineering plastics.
It is made of materials with high compressive and bending strength. The pipe wall is thick, which can effectively prevent deformation or fracture during high-temperature unwinding, and has strong structural strength.
The tube body usually has grooves, recesses or special coatings to enhance the adhesion of the thick yarn and prevent slippage or loose yarn. At the same time, it has excellent dynamic balance performance, which can effectively reduce vibrations and yarn tension fluctuations.
It can adapt to the high temperature and high humidity environment of the spinning workshop, and will not deform or soften. Some fine yarn tubes, such as plastic tubes, can be cleaned and reused multiple times, thereby reducing costs.
