Abstract: A method for manufacturing short fibers includes relaxing entanglement of crimped cellulose acetate fibers in a tow band by applying a tension in a predetermined transfer direction to the tow band transferred in the transfer direction, the tow band containing the crimped cellulose acetate fibers and being impregnated with moisture, and forming short fibers by cutting the tow band in which the entanglement is relaxed.

Abstract: A hydrophilized cellulose acetate tow band according to the present invention includes a crimped cellulose acetate tow band, and a hydrophilizing component having an HLB value of 16 or more. The cellulose acetate tow band includes a cellulose acetate having a degree of substitution of 2.0 to 2.6. The cellulose acetate tow band has a total denier of 10000 to 40000 and is crimped in a number of crimps of 30 to 60 per inch. The hydrophilizing component is impregnated on the cellulose acetate tow band in an amount of 0.2 to 2 weight percent relative to the cellulose acetate tow band. The hydrophilized cellulose acetate tow band may further include a textile oil, where the textile oil is impregnated on the crimped cellulose acetate tow band in an amount of 0.2 to 2 weight percent relative to the cellulose acetate tow band, in addition to the hydrophilizing component having an HLB value of 16 or more.

Abstract: An object of the present invention is to provide a cellulose-based sheet which has excellent transparency, and exhibits excellent adhesiveness when thermally press-adhered. The sheet includes a laminate including a layer formed of a cellulose-based material and a layer formed of a thermoplastic elastomer. Each of molecules forming the thermoplastic elastomer has both a rubber component having entropy elasticity and a molecule-constraining component for preventing plastic deformation.
