Material composition of non-woven fabric
The basic material of non-woven fabric is fiber, which includes natural fibers such as cotton, linen, silk, wool, etc., as well as synthetic fibers such as polyester fiber, polyurethane fiber, polyethylene fiber, etc. In addition, adhesives and other additives need to be added and processed through multiple processes. Due to the use of certain chemicals and additives in the production process of non-woven fabric, some people believe that non-woven fabric is an organic synthetic material.
The difference between non-woven fabric and organic synthetic materials
Although chemicals and additives are used in the production process of non-woven fabrics, they are not organic synthetic materials themselves. Organic synthetic materials mainly refer to high molecular weight compounds obtained through chemical reactions or synthesis, such as polyurethane, polyester, polypropylene, polyethylene, etc. These materials have good chemical stability and plasticity, and are widely used in the manufacture of plastic products, synthetic fibers, etc. In contrast, although non-woven fabrics have added some chemicals and additives during the production process, they are not a polymer compound and do not possess the typical characteristics of organic synthetic materials.
Composition and manufacturing process of non-woven bags
Non woven fabric is a type of textile formed by spinning or non-woven processes using fibers. Unlike traditional fabrics, it is not made by weaving, but by processes such as loosely stacking, gluing, or bonding fibers. Non woven fabrics are usually made from synthetic materials such as polypropylene, but can also be made from natural fibers such as cotton, wool, and some biomass materials.
A non-woven bag is a type of bag made of non-woven fabric. The process of making non-woven bags usually includes the following steps:
1. Raw material preparation: Select suitable non-woven fabric materials and clean and process the materials.
2. Preparation of bag making materials: Non woven fabrics are processed into bag making materials through composite, stacking, bonding and other processes.
3. Decoration such as printing, hot stamping, embroidery, etc.: Decorate non-woven bags according to customer needs.
4. Cutting and Forming: Cut and form the bag making material according to the design requirements.
5. Sewing and edging: Seal the edges of the bag and sew it into shape.
Do non-woven bags belong to organic synthetic materials?
According to the above process flow, we can see that non-woven bags are made of non-woven fabric. The main components of non-woven fabrics are usually synthetic materials such as polypropylene.
From this perspective, non-woven bags can be classified as a type of synthetic fiber material. In contrast, natural fiber materials such as cotton, wool, etc.
However, from another perspective, synthetic materials such as polypropylene are not organic compounds, but rather inorganic compounds. Therefore, from this perspective, non-woven bags can be classified as an inorganic synthetic material.
Conclusion
In summary, non-woven bags can be considered as both a synthetic material and an inorganic synthetic material. The advantages of non-woven bags lie in their simple manufacturing process, ease of processing and production, and good environmental and reusable properties, making them widely used in daily life.
Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
