In the textile printing and dyeing industry, the heald frame is a crucial component of the loom, consisting of an upper and lower beam connected by left and right side bars, equipped with healds and driving elements. When equipped with healds, the heald frame integrates the warp yarns threaded through the healds, allowing them to move up and down in accordance with the opening mechanism of the loom. This motion creates layered openings for the weft yarn to shuttle through, interweaving into fabrics with various patterns.
The external hexagonal bushing, utilized within the heald frame, serves as a connector and wear-resistant element. Crafted from PEEK and its modified composite materials, these bushings can replace traditional components made from copper alloys, stainless steel, polytetrafluoroethylene (PTFE), common engineering plastics, graphite, etc. They meet the stringent technical requirements of textile printing and dyeing machinery, including wear resistance, high-temperature tolerance, high-speed operation, oil-free lubrication, resistance to acid and alkali corrosion, dimensional stability, and non-contamination of fabrics, thereby reducing operational costs, supporting continuous production, and extending component lifespan, ultimately enhancing equipment efficiency and operational stability.
Advantages of PEEK External Hexagonal Bushing:
High-Temperature Resistance: Capable of withstanding long-term use at 260°C and short-term exposure up to 300°C, ideal for high-temperature environments in textile printing and dyeing processes.
Wear Resistance: PEEK and its composites exhibit the best wear resistance among plastics, surpassing copper alloys by over three times.
Hydrolysis Resistance & Low Moisture Absorption: Capable of prolonged operation in water and steam environments.
Corrosion Resistance: Long-term resistance to dyes, acids, alkalis, lubricants, greases, and all organic and inorganic solvents used in textile printing and dyeing industries.
Low Friction & Smooth Operation: Minimal running resistance, eliminating metal-to-metal seizing.
High Strength: Maintains high strength, with a bending strength of 155MPa at 23°C, resisting compression, impact, and fatigue.
Lightweight: Compared to metals, its lighter weight significantly reduces energy consumption.
Self-Lubricating: Eliminates the need for lubricants, preventing fabric contamination and keeping equipment cleaner.
Easy Processing: Enables rapid injection molding of complex, non-standard parts using injection molds, reducing post-processing costs.
This PEEK bushing, with its exceptional wear resistance and self-lubricating capabilities, ensures smooth yarn travel, minimizing yarn breakage due to friction, significantly reducing fabric defects, and lowering downtime for maintenance caused by malfunctions. It significantly enhances production efficiency and product quality while its vibration-dampening and noise-reduction properties create a more comfortable working environment for textile workers.
