The Main Factors Affecting The Performance Of Hot Air Cotton

In the hot air bonding process of Hot Air Cotton, the heat carrier is hot air. As the hot air penetrates the web, heat is transferred to the fibers, melting and creating bonds. Therefore, the temperature, pressure, fiber heating time and cooling speed of the hot air will directly affect the performance and quality of the product.

As the temperature of the hot air increases, the vertical and horizontal strength of the product increases, but the softness of Hot Air Through Nonwoven Fabric decreases and the hand feels hard. The strength and softness are shown as a function of temperature for the production of 16 G / M product.

Hot air pressure is an important parameter affecting hot air bonding products. Generally speaking, as the number and thickness of the Hot Air Cotton Fabric fiber web increase, the pressure should increase accordingly so that the hot air can pass through the fiber web smoothly. However, before the fiber web is bonded, excessive pressure will destroy its original structure and cause the fiber web to be uneven.
