At present, the most environmentally friendly bags are non-woven bags, and the most used is the ultrasonic non-woven welding machine.Here, needle punch nonwoven manufacturer tell,what the advantages of using ultrasound over needle stitching for nonwovens.
The working principle of ultrasonic non-woven welding machine:
needle punched non woven fabric
Ultrasonic non-woven welding machine uses high frequency oscillation to transmit the sound wave to the welding surface of the working object, instantly make the molecules of the working object produce friction, to reach the melting point of plastic, complete the rapid dissolution of solid materials, complete the welding surface of the working object, instantly make the molecules of the working object produce friction, to reach the melting point of plastic, completely sealed
Compared with the traditional stitching method, it has the following advantages:
1.the use of ultrasonic welding technology, no need to change the needle and thread, save the trouble of frequent needle and thread replacement, do not need the traditional sewing way, but also can achieve neat local shear and sealing of textiles.At the same time also plays a decorative role, strong viscosity, can achieve the waterproof effect, embossing clear, the surface more three-dimensional relief effect, fast working speed, good product effect more high-grade beauty;Quality is guaranteed.
2.the use of ultrasonic and special steel wheel processing, so that the sealing edge does not crack, do not hurt the cloth edge, no burr, curling phenomenon.
3.production without preheating, can run continuously.
4.easy to use, and the traditional sewing machine operation method is not much different, general sewing workers can operate.
5.the price is low, 5-6 times faster than the traditional machine, high production efficiency.
