Overview of Ultrasonic Hot Pressing Technology for Non woven Fabric
Non woven fabric is a type of non-woven fabric with thickness, flexibility, and stretchability, and its production process is diverse, such as melt blown, needle punched, chemical fibers, etc. Ultrasonic hot pressing is a new processing technology that utilizes the effect of ultrasonic waves under high-speed vibration, high temperature, and high pressure to fuse the surface of objects and cool and shape them in a short period of time.
After ultrasonic hot pressing, the physical properties of non-woven fabric have been significantly improved, such as strength, durability, and waterproofing. At the same time, ultrasonic hot pressing technology also has the advantages of low energy consumption, high production efficiency, and environmental protection, so it is widely used in the field of non-woven fabric processing.
Applicability analysis of non-woven fabric ultrasonic hot pressing
Although the performance of non-woven fabrics is significantly improved after ultrasonic hot pressing, not all types of non-woven fabrics are suitable for using ultrasonic hot pressing technology. Generally speaking, the following types of non-woven fabrics are suitable for using ultrasonic hot pressing technology:
1. Melt blown non-woven fabric: As it is made by melt blown method, the use of ultrasonic hot pressing technology can better accelerate its setting time, improve its physical strength and waterproof performance.
2. Chemical fiber nonwoven fabric: Due to its stable chemical properties and the use of ultrasonic hot pressing technology, heating time and temperature can be better controlled to achieve better shaping effects.
3. Flexible fiber non-woven fabric: Due to its high flexibility, the use of ultrasonic hot pressing technology can better control the heating range, making it easier to bond together and improve its physical properties.
Advantages and disadvantages of non-woven ultrasonic hot pressing technology
1. Advantages:
(1) High processing efficiency and cost savings in production.
(2) There will be no pollution or noise generated during the processing.
(3) Good shaping effect and high product quality.
2. Disadvantages:
(1) Ultrasonic hot pressing components are prone to damage and require regular replacement.
(2) The range of action of ultrasound is relatively small, which has certain limitations on the size of the processed object.
The application prospects of non-woven ultrasonic hot pressing technology
With the increasing awareness of environmental protection, non-woven ultrasonic hot pressing technology, as a new processing technology, will gradually replace traditional processing methods and become the mainstream of non-woven fabric processing. In addition, with the continuous advancement of technology, it is believed that the application fields of non-woven ultrasonic hot pressing technology will continue to expand, and its application prospects in automotive interiors, household products, protective equipment and other fields will be even broader.
Conclusion
In summary, non-woven ultrasonic hot pressing technology is an efficient, environmentally friendly, and high-quality new processing technology. Although its application scope has certain limitations, with the continuous development and innovation of technology, it is believed that its application fields will become increasingly widespread.
