Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a drying device for nonwoven fabrics. Background Technology

[0002] One existing method for producing nonwoven fabrics is meltblown molding, which involves using high-speed hot air to extremely stretch a fine stream of fibers ejected from a spinneret to form ultrafine fibers, which are then aggregated on a receiving device to form a fiber web. This method produces fibers with small diameters, which is beneficial for improving filtration efficiency. However, currently, meltblown nonwoven fabrics require humidification after the fiber web is formed. This humidified environment causes the fibers to intertwine and strengthen the web, extending its lifespan. After humidification, the nonwoven fabric needs to be dried, but current drying methods generally suffer from long drying times, low efficiency, and incomplete drying. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a drying device for nonwoven fabrics, which can improve drying efficiency and fully dry the nonwoven fabrics.
