THREE-DIMENSIONALLY STRUCTURED NETWORK MATERIAL HAVING AIR GAP

摘要

PROBLEM TO BE SOLVED: To provide a three-dimensionally structured network material having air gap which has coupling parts effectively arranged and consisting of orthogonal couplers and diagonal couplers and has high resistance to compression and high air permeability by using a network system having through-hole parts in both upper and lower sides. SOLUTION: This three-dimensionally structured network material 1 having air gap is made of fiber materials and has both of the upper side 11 and the lower side 12 which have through-hole parts 2 and are coupled with each other by coupling parts 3. The upper side 11 and the lower side 12 are different in through-hole density from each other, and the coupling parts 3 consist of orthogonal couplers 31 and diagonal couplers 32. The through-hole part 2 of the side 11 communicates with.at least one of the through-hole parts 2 of the side 12 between overlapping parts.
