In the textile printing and dyeing industry, the heald frame is an important part of the loom. It is a frame connected by upper and lower beams and left and right side rails with a heald rod and a driving part. After the flat heald is arranged on the heald frame, the warp yarns inserted into the flat heald are gathered into one body. With the movement of the heald lifting mechanism of the loom, the heald frame moves up and down according to the program of the opening device, so that the warp yarns are opened in layers, allowing the weft yarns to shuttle through the warp yarns and interweave into fabrics with different patterns.

The hexagonal bushing is used in the heald frame to connect and resist wear. The hexagonal bushing made of PEEK and its modified composite materials can replace parts made of traditional materials such as copper alloy, stainless steel, polytetrafluoroethylene, ordinary engineering plastics, graphite, etc., and meet the stringent technical requirements of textile printing and dyeing machinery for parts such as wear resistance, high temperature resistance, high speed, oil-free lubrication, acid and alkali corrosion, dimensional stability, and no pollution to fabrics, thereby reducing operating costs and supporting continuous production of machines. It is an ideal choice for extending the service life of parts, improving equipment efficiency and stable operation.

PEEK hexagonal sleeve

The advantages are as follows

High temperature resistant, long-term use temperature is 260℃, short-term use temperature can reach 300℃, suitable for high temperature working environment in textile printing and dyeing process.

Abrasion resistance, PEEK and its composite materials have the best wear resistance among plastics, and the wear resistance is more than three times that of copper alloy.

Hydrolysis resistance, low moisture absorption, can work for a long time in water and steam.

Corrosion resistance, can withstand dyes, acids and alkalis, lubricating oils and greases and all other organic and inorganic solvents used in the textile printing and dyeing industry for a long time.

Friction resistance, low running resistance, and no seizure between metal and metal parts.

High strength, PEEK can maintain high strength, the bending strength at 23℃ can reach 155MPa, compression resistance, impact resistance, and fatigue resistance.

Lightweight, lighter than metal, and significantly reduced energy consumption.

Self-lubricating, not using lubricating oil can avoid pollution to textile printing and dyeing fabrics, and the equipment is also cleaner.

Easy to process, injection molds can be used to quickly inject large quantities of complex special-shaped parts, and the post-processing cost is low.

This PEEK sleeve, with its excellent wear resistance and self-lubricating ability, ensures smooth passage of yarn, avoids breakage caused by friction, greatly reduces the occurrence of fabric defects, and reduces the frequency of downtime and maintenance due to faults, greatly improving production efficiency and product quality. At the same time, the product characteristics of vibration reduction and noise reduction can also create a more comfortable working environment for weaving workers.
