摘要： PROBLEM TO BE SOLVED: To obtain a nonwoven fabric increasing gaps in the laminating direction of constituting fibers and enlarging volume (thickness size) per unit weight of the nonwoven fabric. SOLUTION: This method manufactures the nonwoven fabric by spinning a fiber in semimolten state onto a forming surface 12, comprises a process preparing the forming surface 12 having many projections 13 to which the semimolten state fiber get twisted and a process spinning the fiber in sintered state to the forming surface 12. Each constituting fibers has increased gaps in the laminating direction caused to lamination of many fibers in standing state on the circumference of the projections 13. The gaps between fibers laminated on the forming surface 12 increase because the fibers are supported in a suspension bridge state by the projections or fibers on the circumference of the projections between each projection 13.

摘要： PROBLEM TO BE SOLVED: To efficiently adsorb the evaporated fuel of an internal combustion engine and to efficiently eliminate the evaporated fuel from a fuel steam adsorbing device even in an operating condition of small intake air quantity. SOLUTION: An adsorbing material 31 such as activated carbon is placed on a part of an intake passage 2, for example, inside an air cleaner 21 to efficiently adsorb the evaporated fuel. In order to efficiently eliminate the evaporated fuel adsorbed by the adsorbing material 31 even when the intake air quantity is small, the elimination can be accelerated by directly heating the adsorbing material 31 in the intake passage by some heating means, or by indirectly heating the adsorbing material 31 by heating the intake air. The heating means is controlled in accordance with the operating condition of the internal combustion engine. For example, the heating means is controlled to be operated only in low rotation or low load where the intake air quantity of the internal combustion engine is reduced.

摘要： PROBLEM TO BE SOLVED: To reduce a manufacturing cost of a nonwoven fabric having a functional member. SOLUTION: This method for forming a nonwoven fabric is characterized in that in a method for forming a nonwoven fabric by laminating a fiber 1s in a semimolten state spun from a spinning nozzle 14 to a base material 11n, before the fiber 1s spun from the spinning nozzle 14 reaches the base material 11n, a granular functional member 3 is brought into contact with the fiber 1s. Therefore, the functional member 3 brought into contact with the fiber 1s is fused to a molten part of the fiber 1s and a nonwoven fabric 1 having the functional member 3 is formed at the stage of lamination of the fiber 1s and the functional member 3 to the base material 11n.

摘要： PROBLEM TO BE SOLVED: To enhance the forming efficiency in forming a filter material. SOLUTION: The method of the invention, for producing a filter material by using fiber layers and a functional member sandwiched between the fiber layers, comprises the step of preparing a first fiber layer 21 which has been formed into the same shape as that of one side of the filter material, the step of arranging a functional member 23 on the surface of the first fiber layer 21, and the step of forming a second fiber layer 22 by spinning fibers in a semi-molten state onto the functional member 23 arranged on the surface of the first fiber layer 21. Thus, such a step as of press forming a functional member sandwiched between nonwoven fabrics is made unnecessary and so are the measures to prevent a functional member from falling away and from breaking a nonwoven fabric.
