Non woven fabric bags are environmentally friendly and reusable bags that are highly favored by consumers due to their recyclability. So, what is the manufacturing process and production process for non-woven bags?
The production process of non-woven fabric
Raw material selection: Non woven fabric is a fiber material mainly made of raw materials such as polyester, polypropylene, polyethylene, etc. These raw materials melt at high temperatures, form fibers through special spinning processes, and then interweave the fibers together through chemical or physical methods to form non-woven materials.
Bonding process: The bonding process of non-woven materials mainly includes various methods such as hot rolling, chemical impregnation, and needle punching. Among them, the hot rolling process is to interweave the fibers in the non-woven fabric material through high-temperature hot pressing, forming a solid material. The chemical impregnation process involves soaking non-woven fabric materials in a specific chemical liquid, allowing them to combine with each other in the liquid. The needle punching process uses a needle punching machine to interweave the fibers in the non-woven fabric material together, forming a fixed mesh structure.
The production process of non-woven bags
Design pattern: Firstly, it is necessary to design a suitable pattern based on actual needs and dimensions, taking into account the size, shape, and purpose of the bag, as well as the need to add details such as pockets and buckles.
Cutting non-woven fabric material: Firstly, it is necessary to cut the non-woven fabric material according to the size and shape of the bag.
Assembly of non-woven bag: Assemble the cut non-woven material according to the design pattern of the bag, including sewing the bag opening and adding the bag bottom.
Printing patterns: According to customer requirements, various patterns and texts are printed on non-woven bags.
Hot pressing and shaping: Use a hot pressing machine to heat press and shape the pre made non-woven fabric bag to ensure the stability of the bag’s shape and size.
Complete production: Finally, check if the stitching of the bag is firm, trim any excess threads, and use non-woven bags as needed.
Packaging and transportation: Finally, package and transport the pre made non-woven bag to ensure that the bag is not damaged during transportation.
Cunclusion
In short, the manufacturing process and production process of non-woven bags are very complex and precise, requiring multiple processes for fine processing and assembly. Under the trend of environmental protection, the usage of non-woven bags will continue to increase. Therefore, the production technology and technology of non-woven bags are crucial
