Abstract

The invention discloses a preparation method of an ultraviolet aging resistant polyester spunbonded needle-punched geotextile. The preparation method includes steps of preparation of ultraviolet aging resistant masterbatch and preparation of a spunbonded needle-punched geotextile. Specifically, the step of preparation of the ultraviolet aging resistant masterbatch includes: preparation of polyester chips and functional auxiliaries, high-speed mixing, twin-screw extrusion, pulling, water cooling, pelletizing and drying, wherein the functional auxiliaries include a light stabilizer; the step of preparation of the spunbonded needle-punched geotextile includes: polyester chip feeding, pre-crystallizing, drying, mixing with the ultraviolet aging resistant masterbatch, screw extrusion, prefiltering, melt spinning, cross air blowing, air drawing, yarn swaying for net forming, needling for reinforcement and winding for cloth forming. By mixing of various ultraviolet aging resistant auxiliaries, synergistic effects are achieved, and ultraviolet aging resistance is improved; in addition, by the method, a dispersion effect of the ultraviolet aging resistant auxiliaries in fibers is effectively improved, and accordingly ultraviolet aging resistance of a product is improved, service life of the product is prolonged greatly, and utilization requirements are met.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabric production, in particular to a preparation method of a polyester anti-ultraviolet light aging spunbond needle-punched geotextile. Background technique [0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers by needle punching or weaving. The finished product is cloth, generally 4-6 meters wide and 50-100 meters long. Geotextiles are divided into woven geotextiles and non-woven geotextiles. Geotextile has excellent filtration, isolation, reinforcement and protection, high tensile strength and good permeability. [0003] Polyester spunbond needle-punched non-woven geotextile is a non-woven fabric produced by using polyester (PET) as the original material through processes such as melt spinning, air drafting, and needle punching reinforcement. Polyester spunbond needle-punched geotextile has the advantages of good mechanical properties,...
