Fabric Drying After Water-Jet Insertion
topic
Woven fabric from water-jet looms contains 30 to 60 percent moisture after insertion that must be removed before winding and subsequent processing, using hot air dryers, infrared radiant heaters, or contact drum dryers positioned between the loom fell and the take-up system, with drying energy representing an additional energy cost compared to air-jet weaving, and with insufficient drying causing mould growth in wound fabric rolls during storage that permanently damages the fabric.
Role
Manages the moisture removal requirement that is the primary operational disadvantage of water-jet compared to air-jet weaving, with drying energy adding to the total energy cost of water-jet fabric production and drying system reliability being essential for product quality since inadequate drying causes the mildew damage during storage that makes under-dried water-jet fabric commercially unacceptable despite its otherwise acceptable weaving quality.
