Isotropic nonwovens have approximately the same strength in machine and cross directions. This MD/CD ratio of almost 1:1 makes it easier for converters to further process the nonwoven. Consumers favour the better look and the overall higher tear resistance.
A production for isotropic, hydroentangled nonwovens always contains a crosslapper. Possible configurations are:
Typical web weights: 30 to 400 gsm
Fibers: natural and man-made fibers
Output: some 7,500 tons/year
(depending on fiber type, web weight and working width)
Typical end products: beauty masks, high-quality wipes, coating substrates, technical nonwovens
Precise layering by the crosslapper slows down the entire line significantly. However, the loss of speed can be partially compensated with a subsequent web drafter.
