The principal use for cellulosic fibers within the nonwoven fabrics industry occurs in the blending of cellulosic fibers with polypropylene and polyester fibers. Hydroentanglement is the principal method for manufacturing nonwoven fabrics using blends of cellulosic and polypropylene or polyester fibers. Adding modified cellulosic fibers to nonwoven fabrics based on polypropylene and polyester positively influences tenacity. In hydroentangled nonwoven fabrics, relationships between viscose and lyocell are similar for tenacities in both the conditioned and wet states. Increasing the percentage of manmade fibers increases elongation. Viscose fibers have higher elongation than modified cellulosic fibers. Finer fiber titers and higher degrees of dullness result in higher opacity. Increasing titer thickness and/or the percentage of manmade fibers in the blend increases air permeability.
