In Photography And Eyeglasses, Cellulose Acetate Fibers Are A Common Base Layer

When treated at temperatures similar to cellulose acetate's softening temperature, the tensile strengths of the nonwoven fabric made with a cotton/cellulose acetate nonwoven blend are quite low and not acceptable for consumer application. The use of solvent treatment has allowed for modification of the Cellulose Acetate Fibers Market softening temperature and a decrease in the calendering temperature while preserving improved tensile qualities.

Acetone, a suitable solvent for cellulose fibre, was selected for the solvent pre-treatment; cotton/cellulose acetate nonwovens were given a 20% acetone solvent pre-treatment to lower the softening temperature and further lower the calendering temperature.
