Abstract

The invention discloses a preparation method and product of sunscreen woven bag flat yarn and woven bag. The flat yarn is made of polypropylene, antiaging agent, coupling agent, antioxidant, nano calcium carbonate, polyoxymethylene, linear low density polyethylene , polyethylene wax, ethylene-methyl acrylate copolymer, tributyl citrate, turpentine, ultraviolet absorber and additives are stirred evenly, then plasticized into a molten state at a temperature of 230°C to 240°C, and extruded into a film. It is obtained by cooling, cutting embryo silk, and stretching it into flat yarn. The obtained flat yarn is woven into a sunscreen woven bag. The prepared sunscreen woven bag flat yarn has a good breaking strength retention rate after being exposed to the outdoor atmosphere for one year. and elongation retention at break, and good sun protection performance. The performance and service life of the woven bag after using the flat yarn are improved, and the toughness and tensile strength of the original flat yarn are maintained.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a preparation method of sunscreen woven bag flat yarn and woven bag, and also relates to a product prepared by the method. Background technique [0002] Woven bags are packaging materials for fertilizers, chemical products and other items. The main production process is to use plastic raw materials to extrude film, cut, and unidirectionally stretch into flat yarn, and then weave warp and weft to obtain the product. However, the existing woven bag products are easy to age, have a short service life, and have poor anti-ultraviolet function and low tensile force, which makes the loaded items easily corrupted. Difficult to sort. Therefore, there is an urgent need to improve the performance of woven bag materials, improve the weaving technology of woven bags, improve the sun protection function of woven bags, prolong life and improve tensile properties. Contents of the inventi...
