摘要： PROBLEM TO BE SOLVED: To obtain an inexpensive and high-grade flame-retardant nonwoven fabric good in processability and touch feeling and intended for furniture and bedding of good design.
SOLUTION: The flame-retardant nonwoven fabric combined with long-time flame resistance is obtained at low cost without impairing its good design including touch feeling and visual feeling by blending silicate-containing cellulosic fiber and polyester fiber together. That is, the nonwoven fabric essentially comprises two kinds of fiber, i.e. the silicate-containing cellulosic fiber (A) and the polyester fiber (B), being characterized by being ≥3 cm in thickness, ≤0.017 g/cm
3 in density and ≥70% in thickness recovery percentage.

摘要： PROBLEM TO BE SOLVED: To provide an antibacterial and water-absorbing mat which absorbs blood or the like seeping out of fresh fish or raw meat, thereby preventing the blood from leaking onto a plate and which absorbs waterdrops attached to the bottom surface of the plate so that damage to goods or a leak of waterdrop can be prevented and in which the manner in which water is absorbed cannot be seen from the outside. SOLUTION: In the antibacterial water-absorbing mat, a large number of small recesses are formed on a face sheet, while incisions are formed in the boundary between a side wall and a bottom surface, and one or more pieces of water-absorbing paper or non-woven fabric are adhered to the rear surface of the face sheet, and ε-polygene and/or ε-polygene salt is attached to or is carried by one or more pieces of the paper or non-woven fabric, and further an outer layer sheet is adhered to the rear side of the paper or non-woven fabric.

摘要： PURPOSE:To reuse oil paper without causing damage and thermal deterioration resulting from great shearing force and heating, and to obtain a composite material showing sufficiently strong point of vegetable fiber, by splitting paper, impregnating it with a molten resin, cooling it. CONSTITUTION:Paper is split, impregnated with a dissolved resin, and cooled to give a composite material. A proper amount of water is added in the splitting process. In the impregnation process, the split material and the resin are stirred at high speed, and the split material is impregnated with the resin by rise in temperature caused by frictional heat of them. In the operation, the third component (modified polyolefinic resin, etc.) is added to improve adhesivity.
