Drying and Finishing in Spunlace Production Lines
topic
Spunlace web drying uses through-air drying ovens, infrared drying, or steam-heated cylinder drying to remove the 60 to 80 percent moisture content of the entangled web after water jet processing, with drying temperature controlled to prevent thermal shrinkage of heat-sensitive fibres while achieving full moisture removal before calendering, slitting, or rolling operations that require dry fabric for handling without microbiological growth risk.
Role
Removes the high water content from spunlace webs after hydroentanglement before fabric winding and converting operations, with drying system energy efficiency being a significant operating cost factor in spunlace production where the energy required to evaporate process water represents 20 to 30 percent of total production cost, making drying system selection and optimisation an important economic factor in spunlace production competitiveness.
