During the stretching and setting process of textile printing and dyeing enterprises, the guide rail position of the heat setting machine needs to be adjusted according to the amplitude of different fabrics. The traditional copper alloy amplitude-adjusting nut is prone to being damaged by biting with the metal wire mesh in a high-temperature working environment of about 220 degrees. It is usually necessary to add lubricating oil and spray molybdenum disulfide lubricant, which not only increases the maintenance cost of the setting machine but also easily causes pollution to the fabric. Therefore, it has become a major pain point that plagues textile printing and dyeing enterprises. There is an urgent need for an amplitude-adjusting nut that does not require lubricant to replace the copper nut.

The PEEK, PAI amplitude modulation nuts developed and produced by our company use PEEK (polyetheretherketone) and PAI (polyamideimide) polymers as raw materials. They are formed by injection molding and machining. They have the advantages of high temperature resistance, corrosion resistance, self-lubrication, wear resistance, maintenance-free, and long life. They can reduce the wear on the metal wire rod, and because the PEEK and PAI polymer materials themselves have good self-lubricating properties, the service life of the nut is extended (the life of the PEEK amplitude modulation nut is 3 times that of the copper nut). At the same time, because there is no need to add high-temperature grease and molybdenum disulfide for spraying, the maintenance and use cost of the equipment is greatly reduced, and the fabric can be prevented from being contaminated, thereby ensuring the quality of the printed and dyed fabrics.

The high-performance plastic parts of PEEK (polyetheretherketone) polymer and its composite materials developed by our company have been widely used in various processes such as textile, sewing, non-woven processing, dyeing and finishing, shaping, mercerizing, printing and embroidery. Typical product forms include: wear-resistant sliders, bearings, bushings, dust covers, wear-resistant buffer strips, rail wear strips, amplitude modulation nuts, wear-resistant lifting clips, sleeves, yarn guide wear strips, washers, gears, helical wear plates and nearly 100 kinds of high-performance PEEK plastic parts molding molds and products, which are available all year round.
