Spunlaced wet wipes have a good cleaning effect and are convenient to use, but they have short storage periods and need to add antibacterial agents to prevent deterioration. Therefore, dry towels are gradually becoming popular at present. Existing dry towels mainly use polyester viscose mixed spunlace nonwoven materials and pure cotton spunlace nonwoven materials, which have problems such as insufficient stiffness and easy shedding when wiping. The process route of dry wipes mainly includes: unpacking—coarse opening—fine opening—carding 1—cross-lapping—drawing—carding 2—prewetting—spunlace—rolling liquid—drying—inspection—rolling—inspection —Slitting and packaging for storage, the drying step is particularly important. Drying can make the low-melting point polyester fibers in the fiber web bond, improve the stiffness of the fiber web, and prevent hair loss when wiping. The drying efficiency of existing drying equipment Low, poor drying quality, unable to meet the drying needs of dry towel production.
