Black Woven Bag Thickened Package Express Logistics Snake Skin Fertilizer Bag Sunscreen Anti-Aging Black Woven Bag

Product Description

Product Description

The anti-aging fabric envelope is made of polypropylene and acrylic knitted yarn as raw materials, and is composed of at least two sets of parallel yarns (or knitted yarns). One set is called warp yarn along the longitudinal direction of the loom (the direction of fabric movement), and the other set is called weft yarn in the horizontal layout. Xu Lu uses different weaving equipment and techniques to weave slanted and weft yarns. According to the customer's different size requirements, she sews the burlap bags together. Depending on the range of use, Xu Lu can weave different thicknesses and densities. Generally, knitted geotextiles with relatively thin longitudinal and transverse sections have strong tensile strength (hardness greater than latitude) and very stable performance.
Anti aging woven bags and ordinary woven bags are added with UV sunscreen and antioxidants during the production process, greatly improving the light resistance and weather resistance of carbon smoke woven bags, and enhancing the tensile strength of woven bags. They are widely used in projects with UV protection packaging requirements such as slope protection for landfills, slope protection for fly ash disposal sites, desert management, and water resource flood control projects.

Woven bags are a type of plastic used for packaging, typically made from various chemical plastic materials such as polyethylene and polypropylene; Plastic woven bags are made from polypropylene resin as the main raw material, extruded and stretched into flat threads, and then woven and bagged. Today, we will introduce the production process of woven bags to you:
(1) Raw material mixing and drying: Put polypropylene, polyethylene resin, and filling masterbatch into a drying mixer for mixing and drying, with a drying time of 20-30 minutes and a drying temperature of 100-120 ºC;
(2) Raw material extrusion and molding: The mixed and dried raw materials are placed into an extruder, which is heated by the barrel and sheared by the screw and the barrel to become a molten state. After being extruded into a thin film by the extruder die, it is cooled at a temperature of 40-60 ºC;
(3) Wire drawing: Cut the film into preforms using a blade and stretch them in an oven to form flat threads; After further heat setting, traction shrinkage, and low-temperature treatment, it is compared and then rolled into shape by a winding machine. The traction ratio is 1:4-1:8, and the low-temperature treatment temperature is 30-50 ºC;
(4) Weaving: After the winding is formed, it is loaded into the shuttle magazine. Under the push of the shuttle pushing device, the shuttle moves in a circular motion. With the close cooperation of the warp supply system and the shuttle pushing device, it is woven into a cylindrical flat fabric. After comparison, it is wound by the winding machine behind the warp frame. When the diameter of the wound coil reaches 1.2-1.4m, it is unloaded;
(5) Printing and cutting: The qualified woven fabric produced in the previous process is printed with a printing machine to form product related information on the woven fabric, and then cut into the required size by a bag cutting machine;
(6) Sewing: Cut the woven fabric and use a sewing machine to make plastic woven bags.
