Abstract: An object of the present invention is to provide an industrially advantageous method for producing a bisimide dicarboxylic acid, which uses substantially no solvent and requires no granulation after completion of the reaction.The above object can be achieved by a method for producing a bisimide dicarboxylic acid with a tricarboxylic acid anhydride and a diamine, including the following processes (i) and (ii): a process (i) in which, provided that a compound having a higher melting point is a high melting compound and a compound having a lower melting point is a low melting compound, when a melting point is compared between the tricarboxylic acid anhydride and the diamine, the high melting compound is heated at a temperature between less than the melting point of the high melting compound and not lower than the melting point of the low melting compound, and the low melting compound is added to the high melting compound while the high melting compound maintains its solid states, to give a mixture; and a process (ii) in which the resultant mixture in the process (i) is heated while its solid states are kept, to give bisimide dicarboxylic acid.

Abstract: [Problem] To provide an air filter material in which spun bond nonwoven fabric and melt blown nonwoven fabric are laminated and integrated without reducing air permeability.[Solution] Spun bond nonwoven fabric comprises, as constituting filament, conjugate polyester continuous filaments having a cross-sectional shape of a nearly “Y4”-like shape. The continuous filament is composed of a nearly V-shape portion 6 in the nearly Y4-like shape, formed from low melting point polyester, and the other nearly+shape portion 5 therein, formed from high melting point polyester. The continuous filaments are heat-bonded with each other by the low melting point polyester. The spun bond nonwoven fabric is bonded by a powder type or spider web type hot melt adhesive agent with the melt blown nonwoven fabric.

Abstract: The primary cloth is stabilized after a tufting step. The primary cloth is a nonwoven fabric of continuous filaments which are more than 10 dtex in fineness. The continuous filament is consisting of polyester which has a nearly ‘V’ part made of a low melting point polyester and a nearly ‘+’ part made of a high melting point polyester. The continuous filaments are one other bonded by melting or softening of the low melting point polyester to form the nonwoven fabric.

Abstract: The packaging material for cold forming of the present invention includes a polyamide resin film biaxially stretched by a tenter method and an aluminum foil provided on one surface of the polyamide resin film and integrated with the polyamide resin film. The distortion of the polyamide resin film caused by applying thereto a tension corresponding to the tensile break tension of the aluminum foil is 20% or more and 45% or less. Herewith, it is possible to provide a packaging material for cold forming excellent in cold formability, capable of suppressing the breakage of the aluminum foil during the cold forming in the case where the polyamide resin film biaxially stretched by the tenter method is used.
