Detailed explanation of the production process of non-woven bags
1、 Overview
Non woven bag is an environmentally friendly and reusable bag made from chemical fibers such as polyester and polypropylene. Compared with traditional plastic bags, non-woven bags have higher strength, better breathability, and waterproofness, and are widely used in shopping bags, gift bags, promotional bags, and other fields.
2、 Production process
1. Raw material screening
The first step in making non-woven bags is to screen the raw materials. When screening raw materials, factors such as fiber length, strength, and flexibility need to be considered to ensure the success of subsequent steps.
2. Forming
There are two ways to form non-woven bags: hot forming and chemical forming. Regardless of the method, the purpose of molding is to arrange and fix the fibers side by side.
3. Cutting
The formed non-woven fabric needs to be cut. When cutting, attention should be paid to the size and shape of the bag to ensure subsequent sewing.
4. Sewing car
Sewing is the final step in the production of non-woven bags, which aims to sew the various parts of the bag together. When sewing, it is necessary to consider the weight capacity and aesthetic appeal of the bag.
3、 Precautions
The selection of raw materials is very important, and it is necessary to choose high-quality fibers to ensure the strength of the bag.
2. During molding, it is necessary to control the density and tension of the fibers to ensure the load-bearing capacity and aesthetic appeal of the bag.
3. When cutting, it is necessary to accurately measure the size and shape of the bag to avoid wasting raw materials and affecting the effectiveness of the bag.
When sewing the car, high-quality sewing thread should be selected to ensure the strength and aesthetics of the bag.
4、 Conclusion
Through the introduction in this article, I believe everyone has gained a deeper understanding of the production process of non-woven bags. To produce a high-quality, aesthetically pleasing non-woven bag, strict control is required through multiple steps such as raw material screening, forming, cutting, and sewing.
