Problems solved by technology

With the continuous development of technology, the existing technology uses manipulators to carry and feed woven bags, but the surface of woven bags made of polypropylene is smooth, and the frictional adhesion to the manipulator is not enough, so it is easy to appear in the process of handling and feeding. Slipping, causing danger to people or causing loss to materials, and in the prior art, woven bags containing materials are stacked and stored by stacking up and down, the contact area between woven bags is small and does not have anti-skid performance, and stacked woven bags are prone to Tilted and collapsed, causing a safety accident

Embodiment 1

[0030] The invention provides a method for manufacturing a flame-retardant non-slip woven bag, comprising the following steps:

[0031] S1: Blending and drying of raw materials: put polypropylene particles, calcium carbonate, and additives into a drying mixer and stir to dry;

[0032] S2: wire drawing process: after the blending and drying of step S1, the material enters the extruder, is heated by the barrel and sheared by the screw and the barrel, is extruded into a film through the die, and passes through the water of 30-40 ℃ After cooling, the embryos are cut into filaments with a blade, and stretched through a drying plate to form flat filaments. After the flat filaments are heat-set, they are collected into rolls by a wire winding machine;

[0033] S3: Weaving process: weave the rolled flat yarn into a cylindrical woven bag through a circular loom, and after passing the inspection, wind up through a winder;

[0034] S4: Preparation of anti-slip coating: 100 parts of chlo...

Embodiment 2

[0038] The invention provides a method for manufacturing a flame-retardant non-slip woven bag, comprising the following steps:

Description

technical field [0001] The invention relates to the technical field of plastic woven bags, in particular to a method for manufacturing a flame-retardant non-slip woven bag. Background technique [0002] Polyolefin plastic woven bags have been widely used since they came out because of their lightness, thinness, firmness, waterproof, mildew resistance, and low price. With the continuous development of technology, the existing technology uses manipulators to carry and feed woven bags, but the surface of woven bags made of polypropylene is smooth, and the frictional adhesion to the manipulator is not enough, so it is easy to appear in the process of handling and feeding. Slipping, causing danger to people or causing loss to materials, and in the prior art, woven bags containing materials are stacked and stored by stacking up and down, the contact area between woven bags is small and does not have anti-skid performance, and stacked woven bags are prone to Tilt and collapse, cau...
