Description

TECHNICAL FIELD

[0001] The present application relates to the field of water-jet nonwoven fabric production equipment, in particular to a water-jet nonwoven fabric drying device. BACKGROUND

[0002] Water-jet nonwoven fabric is a kind of fabric that is made by spraying high-pressure micro-fine water flow to one or more layers of fiber web, so that the fibers are entangled with each other, thus reinforcing the fiber web and making it have certain strength.

[0003] During the water-jet processing, the water flow fully contacts the water-jet nonwoven fabric, and the water-jet nonwoven fabric is full of moisture, so it is necessary to dehydrate and dry the water-jet nonwoven fabric. The traditional dehydration methods include extrusion dehydration and hot air drying. During the drying process, the extrusion rollers can only adjust the distance between the extrusion rollers in the vertical direction by rigid extrusion to achieve dehydration. If the distance between the extrusion rollers is too small, the nonwoven fabric body is easily damaged, and if the distance between the extrusion rollers is too large, the extrusion dehydration effect is poor. In addition, the traditional drying method is a drying method by blowing hot air. The hot air cannot be in contact with the surface of the nonwoven fabric for a long time, and the drying speed is slow. SUMMARY
