China's textile machinery development there are two main problems: one is the spinning machine equipment running speed is low, the second is the average energy consumption of equipment is high. In order to further reduce energy consumption, improve production efficiency, textile machinery and equipment began to gradually apply carbon fiber materials in the parts. Carbon fiber is light in quality, but the specific strength is very large, is the ideal material for the lightweight of high-end machinery and equipment. The following is for the current textile machinery in the application of carbon fiber in several forms to do a brief introduction.

Shuttles and arrow shafts:
Shuttle and arrow rods are the earlier forms of carbon fiber composites applied in textile machinery. Wooden shuttle rods weigh 1.2kg each, while the weight of carbon fiber rods is only 0.1kg; the frequency of wooden shuttles is about 120-130 times / min, the frequency of carbon fiber composite rods can be at least doubled; the service life of wooden shuttles is only 6 months, while the service life of carbon fiber composite rods is as long as 6-8 years.

Carbon fiber heald frames and thread wrapper cores:
Later, with the shuttleless loom, the number of revolutions was increased, the width of the fabric became wider, and productivity increased significantly. In the water-jetted hole chamber, the rotational number is 1700rpm and the loom width is up to 2m. In order to suppress the deformation of the long and large loom, lightweight and highly rigid carbon fiber composite materials are used in the heald frames. The winding core of the loom thread wrapper is usually a steel tube, which is inserted into the paper tube, and when air pressure is added, it produces a small protrusion, which becomes a structure for fixing the paper tube, but the drawback is the high weight. After replacing it with a carbon fiber composite tube, the weight is reduced a lot, and it is inserted into a straight tube, making both the loom installation work and the human work of removing it from the rolled fabric much easier.

Carbon fiber reinforced nylon gears:
Traditional spinning machine equipment with gears is mainly pure nylon gears, due to low strength, poor fatigue resistance, short life cycle, high maintenance costs, but the use of carbon fiber reinforced nylon made of transmission gears conductive, anti-static effect is good, not only with the general conductivity of the cast iron parts, but also effective in preventing the generation of static electricity to reduce the incidence of fire and other accidents; strength, toughness, tensile strength is close to the yield Strength, impact, stress vibration has a strong energy absorption capacity; wear-resistant, self-lubricating effect, reduce oil, fatigue resistance, service life can be doubled; light weight, low noise, noise than cast iron gears lower than 30%, reduce energy consumption by 20%, corrosion-resistant, resistant to gasoline, oil and grease, alcohol, alkali and other erosion.

The above application of carbon fiber materials is still limited to small or small number of parts, in these parts of the value of carbon fiber materials has not been highlighted, compared to this, the application of carbon fiber roller shaft is one of the most promising direction of the lightweight application of textile machinery in recent years.

Carbon fiber rollers:
Roller as one of the main running parts in the textile machinery, the overall equipment performance of the textile machinery has a great impact on the quality and stability of the product has a direct force. According to the domestic carbon fiber roller of the main producer of the Wuxi Zhi on the new material responsible person, the traditional textile machine with the majority of rollers are steel, steel roller weight, equipment, high energy consumption, in order to meet the demand for speed but also to continue to increase the wall thickness, thus triggering a series of drawbacks. The use of carbon fiber rollers can simultaneously meet the light weight, high speed, good stiffness, small deformation, low energy consumption and other needs.
