Abstract
PURPOSE: To obtain a fiber changing little in size by a method wherein material paper is prepared by combining refined natural cellulose pulp with an inorganic fiber whose ratio is less than a fixed percent in relation to the whole paper material and the material paper thus prepared is dipped in the rich solution of zinc chloride, then being laminated, matured, washed by water, dried, pressurized and finished.
CONSTITUTION: An organic natural fiber as material paper laminated and united by the use of the swelling reaction of the solution of zinc chloride is combined with an inorganic fiber having no swelling reaction, such as glass fiber, carbon fiber and mineral fiber, so as to prevent the expansion and bending at the bent place owing to the inferior adhesiveness. The ratio of the inorganic fiber is set to be 20% or less in the whole. Since the inorgnaic fiber is free from water- and humidity-absorbing property and is hard and tough, it can control the free expansion and shrinkage of the natural fiber and prevent the change in size.
