Non woven fabric, as a new type of material, has characteristics such as moisture absorption, breathability, waterproofing, anti fouling, and wear resistance, and is widely used in various industries. In the production of non-woven fabrics, welding is undoubtedly one of the key processes. The quality of welding not only affects the appearance and service life of the product, but also relates to the safety of the product. How should we choose the appropriate welding frequency and power for different types of non-woven fabrics?

Firstly, it should be clarified that the melting point and softening point of non-woven fabrics are relatively low, so it is necessary to choose a lower power and frequency when welding non-woven fabrics. If the power and frequency are too high, it can lead to obvious melting, deformation, and burning of the welding surface, seriously affecting the welding quality and product reliability. Therefore, selecting the appropriate power and frequency is a special issue to pay attention to when welding non-woven fabrics.

Generally speaking, suitable welding frequency and power should be selected for different types of non-woven fabrics. For example, for thinner non-woven fabrics, lower power and frequency should be chosen; For thicker non-woven fabrics, it is necessary to choose higher power and frequency. In addition, different non-woven fabric materials can also have an impact on welding frequency and power. For example, for non-woven fabrics made of thermoplastic materials such as polyester fibers, lower power and frequency should be chosen; For non-woven fabrics made of thermosetting materials such as polypropylene, it is necessary to choose higher power and frequency.

It should be noted that when selecting welding frequency and power, adjustments should also be made based on the actual situation of the welding machine. Welding machines of different brands and models may have different parameters such as power and frequency, so adjustments need to be made based on the specific model parameters. During the use of the equipment, it is also necessary to continuously optimize parameters based on the actual welding effect to obtain the best welding effect.

In short, choosing the appropriate welding frequency and power is very important for welding non-woven fabrics. Only by welding under appropriate parameters can welding quality and product reliability be guaranteed. Therefore, when welding, it is necessary to carefully select frequency and power, continuously optimize parameters, and ensure that the welding quality reaches the best effect.
