Abstract

The invention discloses an anti-aging polypropylene fiber and a preparation method thereof. The anti-aging polypropylene fiber is a sheath-core fiber. The sheath is prepared from an anti-aging polypropylene fiber material. The core is prepared from ordinary polypropylene. The anti-aging polypropylene fiber is composed of polypropylene, an antioxidant, a UV absorber, a light stabilizer and carbon black. The preparation method is simple. The product has excellent anti-aging properties and excellent mechanical properties and can be used for a non-woven geotextile.

Description

technical field [0001] The invention relates to an anti-aging polypropylene fiber and a preparation method thereof. Background technique [0002] The existing polypropylene fiber has a single component, unsatisfactory anti-aging performance, and obvious decline in strength, which limits the scope of use and service life, and needs further improvement. Contents of the invention [0003] The object of the present invention is to provide an anti-aging polypropylene fiber with excellent anti-aging performance and a preparation method thereof. [0004] Technical solution of the present invention is: [0005] An anti-aging polypropylene fiber, characterized by: linear density: 2.5-10dtex, breaking strength: 4.5-6.5 cN / dtex, breaking elongation: 15-30%; it is a sheath-core fiber, and the sheath component is anti-aging Polypropylene fiber material, the core component is ordinary polypropylene; by weight percentage: skin component 50%, core component 50%; [0006] The skin layer...
