摘要： PROBLEM TO BE SOLVED: To provide flat rayon fibers which are less adherent to each other so as to be easily loosened, which are relatively bulky, and which can be produced at low cost; to provide a method for producing the same; and to provide a fiber assembly using the same.SOLUTION: A flat rayon fiber (1) of the invention has a cross section (2) of a flat shape and longitudinal streaks (4) formed in the longitudinal direction on the side surface of the fiber. As viewed from the fiber cross section, the flat rayon fiber (1) has portions where creases (2b and 2c) are formed on the outer periphery. In the interior of the cross section (2), the flat rayon fiber (1) contains a portion (3) formed by crushing a cavity so that the inner walls of the cavity are in close contact with each other. In a rayon fiber spinning process for extruding a spinning solution containing viscose through a nozzle into a spinning bath to regenerate a rayon fiber, the flat rayon fiber is produced by generating foam from the spinning solution containing viscose to form cell-like cavities in the fiber and by bringing the inner walls of each of the cell-like cavities into close contact with each other during drying to flatten the fiber. The fiber assembly of the invention contains the flat rayon fibers in an amount of at least 20 mass%.

摘要： PROBLEM TO BE SOLVED: To prepare viscose rayon having three kinds of hollow shapes by controlling aging degree (Hottenroth value) of viscose and addition amount of sodium carbonate. SOLUTION: This method for producing hollow viscose rayon comprises using viscose in which values of X and Y are set so as to satisfy the formula Z=XY/7 (Z is a numerical value which approximates 4, 7 or 10) when addition amount of sodium carbonate to weight of viscose is defined as X wt.% (X is 2.5 to 5.5) and aging degree (Hottenroth value) of viscose is defined as Y. Thereby, a hollow viscose rayon whose shape is a hollow flat type when Z is about 10, a hollow bamboo knot type when Z is about 7 or closed small cell type when Z is about 4 can be produced.
