Abstract

The invention discloses a method for producing container bag by using ribbon-like filaments. The method comprises the following steps: (a) burdening: burdening porcelain white weft silks and porcelain white warp silks respectively, wherein the porcelain white weft silks consist of the following raw materials in parts by mass: 100 parts of polypropylene, 0.2-5 parts of anti-ultraviolet agent, 1-8 parts of modifier and 1-3 parts of softening agent; the porcelain white warp silks consist of the following raw materials in parts by mass: 100 parts of polypropylene, 0.2-5 parts of anti-ultraviolet agent, 1-15 parts of modifier and 1-20 parts of PP white reclaimed material; (b) drawing: uniformly mixing the two types of materials according to a certain proportion respectively, adding the mixture into a plastic drawing machine for drawing to make porcelain white weft silks and porcelain white warp silks for webbing and weaving; (c) webbing and weaving: weaving the porcelain white weft silks and porcelain white warp silks into a ribbon-like filament ribbon and a ribbon-like filament fabric respectively by using a weaving machine; (d) cutting: cutting the woven ribbon-like filament fabric into fabric pieces according to the shape of bag to be produced; (e) sewing: sewing the fabric pieces cut into certain shapes into a bag body, and sewing the ribbon-like filament bag on the bag body according to the requirement of the container bag while sewing the bag body in order to construct a complete container bag; (f) finishing and packing.

Description

technical field [0001] The invention relates to a method for producing container bags with flat yarn, which belongs to the technical field of plastic weaving and production. Background technique [0002] At present, the plastic woven bags produced, sold and used at home and abroad all use polypropylene resin (PP) as raw material to make flat yarns, and then weave them into woven bags for packaging items. Because polypropylene woven bags are easy to separate from the packaging, light in weight and low in cost, they have been widely used in the packaging of bulk products such as chemicals, mineral powders, building materials and grains. However, due to the poor weather resistance and easy oxidation of PP, it leads to its oxidative degradation. During the storage process, the mechanical strength of the woven bag, especially the impact strength, is greatly reduced, which affects the packaging effect. Contents of the invention [0003] The purpose of the present invention is t...
