Abstract

The invention discloses a method for preparing anti-aging plastic woven bag ribbon-like filaments and relates to the technical field of woven bags. The anti-aging plastic woven bag ribbon-like filament prepared by adding a self-made modified aluminum borate crystal whisker and a modified composite fiber has good mechanical properties, and meanwhile is excellent in ultraviolet aging resistance, andultraviolet aging tests show that the tension strength retention rate is up to 97%.

Description

technical field [0001] The invention belongs to the technical field of woven bags, in particular to a preparation method of anti-aging plastic woven bag flat yarn. Background technique [0002] Woven bag, also known as snakeskin bag. It is a kind of plastic bag, which is used for packaging. Its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. The color of the woven bag is generally white or off-white. It is made of various chemical plastics, but its environmental protection is strong, and its recycling is relatively strong; woven bags are widely used, mainly used for packaging and packaging of various items, and are widely used in industry. [0003] The patent (application number 201410735982.9) discloses the preparation method and products of sunscreen woven bag flat yarn and woven bag, and specifically discloses the sunscreen made of polypropylene, anti-aging agent, coupling agent, antioxidant, nano-calcium carbonate, ...
