Definition and production process of polyester non-woven fabric
Polyester non-woven fabric is a non-woven fabric formed by spinning polyester filament fibers or short cut fibers into a mesh, characterized by no yarn or weaving process. Polyester non-woven fabrics are generally produced using methods such as melt blown, wet, and dry methods.
Taking the melt blown method as an example, polypropylene is first melted at high temperature, and then polypropylene fibers are injected into an accelerated airflow through a nozzle to form a fiber mesh structure. Finally, the fiber mesh is reinforced by a compression roller. This forms a non-woven fabric with low porosity and airtightness, which has good physical properties and chemical stability.
Application of polyester non-woven fabric in various fields
1. Home field
Polyester non-woven fabric has a wide range of applications in the home field, such as making bedding, curtains, foam pads, etc. It has the advantages of anti mold, waterproof, breathable, wear-resistant, and easy to clean, which can bring people a healthier and more comfortable living environment.
2. In the field of agriculture
The application of polyester non-woven fabric in the agricultural field is mainly as a covering material, which can effectively protect crops and fruit trees from pests and harmful gases; At the same time, it can also increase soil temperature, improve soil environment, and save water.
3. Medical field
The application of polyester non-woven fabric in the medical field is mainly for surgical area padding, masks, surgical gowns, etc. It has the advantages of not easy to peel off, waterproof, antibacterial, breathable, etc., which can effectively protect the health and safety of medical staff and patients, and avoid the risk of cross infection.
4. Industrial sector
Polyester non-woven fabric is widely used in industrial fields, such as automotive interiors, filter materials, sound insulation materials, composite materials, building waterproofing materials, etc. With its good strength and wear resistance, it can bring a more efficient and safe production environment to industrial production.
In short, polyester non-woven fabric, as an excellent new material, is increasingly widely used in various fields. It not only meets people’s requirements for material quality, but also is an environmentally friendly and sustainable new material that will continue to play a more important role in future development.
Pay attention to the wrinkling of polyester non-woven fabric
Analysis of Wrinkle Causes
1. Improper material selection. The combination of polyester fabric and non-woven fabric is prone to wrinkling when rubbed against each other. If the non-woven fabric is thicker and has higher rigidity, its friction with polyester fabric will be stronger, resulting in more obvious wrinkling phenomenon.
2. Improper process control. Improper compounding temperature and pressure can cause wrinkles when compounding polyester fabric with non-woven fabric. Especially when the temperature setting is too low or the pressure setting is not large enough, it can cause the material to not fully fuse, resulting in wrinkles.
Solution
1. Increase the composite temperature. Increasing the temperature will make polyester fabric more easily melted, making it easier to fully bond with non-woven fabric and reducing the likelihood of wrinkles.
2. Adjust the composite pressure. Appropriately increasing the pressure during the use of polyester and non-woven fabrics can completely squeeze out the air between the two, making the materials tightly bonded and reducing the possibility of wrinkles. However, the pressure should not be increased too much, otherwise it will cause the material to bond excessively and become too hardened.
3. Increase the specific gravity of polyester fabric. Choosing a higher density polyester fabric can make the surface of the material smoother, thereby reducing wrinkles caused by excessive friction.
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.
