Understand the precautions for the use and production of polypropylene staple fiber!

Polypropylene staple fiber is widely used in many fields, with high strength, low weight, acid and alkali resistance and other excellent properties. However, there are several key considerations to keep in mind during use and production to ensure safety and effectiveness.

First of all, the melting point of polypropylene staple fiber is low, so special attention should be paid to temperature control during hot processing. Avoid prolonged exposure to high temperatures to prevent melting and combustion. Secondly, the spinning temperature of polypropylene staple fiber should be controlled during the spinning process, usually above 300℃. The spinning temperature required for different specifications of polypropylene staple fiber is very different, and improper temperature control may lead to problems such as hair, broken ends or the strength of the finished product. In addition, because polypropylene fiber is easy to produce static electricity, the workshop should maintain appropriate temperature and humidity to reduce static electricity.

When using polypropylene staple fiber, it is necessary to pay attention to its chemical characteristics. Although polypropylene has strong chemical resistance, the use of mineral oil lubricants and unidentified organic solvents should be avoided to prevent damage to the fiber. In addition, the friction generated by polypropylene fiber is generally negative static electricity, and cationic systems should be selected when adding antistatic agents.

In recent years, Jiangsu Haibang New Materials Co., Ltd. has developed a large number of polypropylene short fiber varieties, including high-speed iron foundation high strength high modulus polypropylene, lightweight GMT hot melt polypropylene, automotive structural parts strengthened polypropylene, liquid filtration adsorption polypropylene, wear-resistant high strength polypropylene, low odor low VOC polypropylene, dyeing polypropylene, halogen-free flame retardant polypropylene and other cutting-edge fiber products. It replaces many import needs. We have successfully served polypropylene staple fiber products in high-end industries such as high-speed railway, Three Gorges Dam, all kinds of medium and high-end automobiles, direct drinking water, etc., and the product quality has reached a high level, saving a lot of investment for national projects.
