Polypropylene staple fiber: a versatile material with excellent performance

Polypropylene staple fiber, that is, polypropylene staple fiber, is a kind of polypropylene resin as raw materials, through melt spinning, drawing, crimping, drying, shaping, cutting, packaging and other processes made with a specified size and length of fluffy fiber.

High strength: the strength of polypropylene staple fiber is similar to high strength synthetic fibers such as polyester and nylon, but the wet strength is almost unchanged, which is better than nylon.

Wear resistance and corrosion resistance: polypropylene staple fiber is not only wear-resistant, but also has significant stability to inorganic acids and alkalis, suitable for harsh environments.

Poor hygroscopic: polypropylene is almost non-hygroscopic, and the moisture regain rate is less than 0.03%, but fine denier polypropylene has a strong core absorption effect.

Electrical insulation and heat preservation: polypropylene has high electrical resistivity, small thermal conductivity, and good electrical insulation and heat preservation.

Anti-aging: Although the heat resistance and aging resistance of polypropylene are poor, its anti-aging performance can be improved by adding anti-aging agents.

Application areas of polypropylene staple fiber

Textile industry: polypropylene staple fiber can be used to produce non-woven fabrics, nonwovens, wool, polypropylene yarn, carpet and other textile products.

Geotextile: polypropylene staple fiber needled geotextile is widely used in highway, railway, water conservancy, electric power, environmental protection and other engineering fields, with good mechanical properties, durability and adaptability.

Environmental protection projects: polypropylene staple fiber non-woven geotextiles are used in soil and water conservation, environmental governance and other projects, which can prevent soil erosion and protect the environment.

Filtration industry: The excellent filtration performance of polypropylene staple fiber makes it widely used in the field of filter materials, such as water filtration, oil filtration and so on.
