The concept of hot pressing and sewing
Non woven fabric is a type of non-woven woolen fabric made from short or long fibers processed through processes such as spinning, needle punching, or thermal bonding. Hot pressing and sewing are two common processing methods for non-woven fabrics.
Hot pressing is the process of applying high temperature and pressure to non-woven fabrics through a hot press machine, followed by hot melting and compaction treatment, to form a dense surface structure. Car sewing is the process of sewing the edges of non-woven fabric using a sewing machine.
The difference between hot pressing and sewing
1. Different surface effects
The non-woven fabric treated by hot pressing has a smooth and dense surface, with good hand feel and stiffness, and is not easily deformed, fuzzy or pilling; The non-woven fabric processed by sewing has obvious seams and thread ends, which are more prone to pilling and deformation.
2. Different processing costs
Hot pressing processing is relatively simpler than sewing, and can achieve non cutting and non sewing processing, so it is relatively lower in cost.
3. Different usage environments
Non woven fabrics that have undergone hot pressing treatment have strong waterproof, antibacterial, and UV resistant properties, making them suitable for industries such as outdoor products and hygiene products; The non-woven fabric processed by sewing cannot guarantee waterproof performance due to the presence of seams and thread ends, so it is more suitable for industries such as household goods and clothing.
Application of hot pressing and sewing
1. Hot pressing processing is widely used in the processing of non-woven handbags, medical masks, protective clothing and other products.
2. Sewing processing is widely used in the production of non-woven bed sheets, curtains, backpacks and other products.
Conclusion
In short, although hot pressing and sewing are common non-woven fabric processing methods, they differ in surface effect, processing cost, usage environment, and application fields. In practical applications, it is necessary to choose the most suitable processing method based on the specific needs of the product.
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.
