Polypropylene staple fiber is a synthetic material made of multiple processes, which is widely used in many engineering fields. The processing process includes raw material pretreatment, carding and laying, needle processing and hot air shaping. First, the polypropylene staple fiber raw material needs to be pre-treated to improve its spinnability. Then, the fibers are evenly laid into nets through the carding machine, and then the needling machine punctures the fiber nets to make the fibers entangled with each other to form a fiber layer with a certain thickness. Finally, after hot air molding treatment, the fiber layer is stably formed and its mechanical properties are enhanced.

Polypropylene staple fiber has a variety of excellent properties, such as good water permeability, corrosion resistance, wear resistance, and high tensile strength and elongation. This makes it widely used in water conservancy engineering, road engineering, construction engineering and other projects. For example, it is used for seepage prevention and drainage in water conservancy projects, for roadbed treatment and drainage in road projects, and plays a role in soft foundation reinforcement and slope protection in construction projects.

The processing method of polypropylene staple fiber not only improves the production efficiency, but also reduces the construction cost.

Hubei Botao Synthetic Fiber Co., Ltd. was founded in October 2000, located in Jingmen City, Hubei Province, specializing in the production and sales of polypropylene, polyester, composite fiber, polylactic acid staple fiber, the products are mainly used in non-woven fabrics, automotive interior, geotextiles, carpets, filtration and other industries. With the continuous development of the company, Jiangsu Botao New Materials Co., LTD., Hubei Lvhuan Chemical Fiber Co., LTD., and Tianlong (Thailand) Co., Ltd. have been established at home and abroad, with a total area of 300,000 square meters. The company has introduced a number of imported fiber production lines, with fixed assets of more than 300 million yuan, an annual output of 100,000 tons of polypropylene staple fiber, 20,000 tons of polyester staple fiber, 10,000 tons of composite fiber, and an annual output value of over 800 million yuan. Focusing on the field of synthetic fiber for more than 20 years, Botao synthetic fiber has obtained excellent market results and extensive honors with the mentality of excellence and integrity development. In 2014, as the vice president unit of the polypropylene Branch of China Chemical Fiber Association, participated in the drafting and formulation of the "polypropylene staple fiber" industry standard; In 2018, it won the invisible champion in the pillar industry segmentation field of Hubei Province Science and Technology Small Giant, which is a provincial specialized and special new small giant enterprise......
