摘要：
A process for drying/heat-treating nonwoven webs in which the web (1) is partially dried under tension in a first drying zone (2) and further heat treated under low tension or in a substantially tensionless state a second drying zone (6, 7). The process significantly reduces the occurrence of stretch-type defects in the nonwoven webs.
