つた。Next, embodiments of the present invention will be described with reference to specific examples. The parts and% in the examples relate to the weight unless otherwise specified. Comparative Example 1 A wholly aromatic polyester composed of P-hydroxybenzoic acid and 6-hydroxy-2-naphthoic acid was obtained by spinning.
A fully aromatic polyester fiber (cutting strength 23.7 g / dr, breaking elongation 4.5%) 450dr-30fil filament yarn was used to make a knitted fabric with a mesh spacing of 3 mm by the Russell weaving method, and immersed in a vinyl chloride resin emulsion solution. Treated, dried sheet-like material, a pair of draw-forming rolls of a roll having a concave portion and a roll having a convex portion on the surface, the convex portion 15mm in diameter, depth 15
mm, the roll interval is 8 mm, and the roll surface temperature is 180 ° C and the cylinder gauge pressure is 2.0 kg / cm 2 and press processing is performed, and many projections are arranged on the mesh structure sheet by deep drawing. A honeycomb structure sheet-like material [I] having the provided recesses (average elongation at the time of cutting was 4%) was obtained. This sheet-like material [I] was entirely covered with a sheet-like material of fibers mainly composed of polyester short fibers as shown in FIG. 2, and the surface thereof was further covered with a cloth to form a mattress. This mattress had a more stable body than the conventional mattress made entirely of cotton, had no discomfort due to sweating, and was comfortable to sleep. However, if the product was continued to be used for a long period of time, the sheet-like material was deformed due to the weight, and the effect at the beginning of use was not obtained. Example 1 A strand obtained by compounding a filament yarn of 450dr-30fil of wholly aromatic polyester fiber of Comparative Example 1 and a filament yarn of 75dr-10fil of 6-nylon fiber was used. Make a knitted fabric (cutting elongation 4.8%),
This knitted fabric was kept in a tensioned state between rolls installed before and after the heating furnace, heat-treated at a heating furnace temperature of 235 ° C., then wound through a cooling roll, and subjected to melt-bonding treatment of 6-nylon fiber to obtain a mesh structure. After fixing the texture structure of the knitted fabric, the sheet-like product obtained by immersion treatment in a phenolic resin composition liquid and drying is composed of a roll having concave portions on the surface and a roll having convex portions, as in Comparative Example 1. A pressing process was performed with a pair of draw-forming rolls to obtain a honeycomb structure sheet-like material [II] (average elongation at the time of cutting was 3%). A 15 mm thick flame-retardant polyurethane foam is laminated on both sides of this sheet-shaped material [II], and a non-woven fabric of flame-retardant polyvinyl alcohol fiber having an average basis weight of 250 g / m 2 is laminated thereon, and a decorative board Was laminated to produce a soundproof partitioning member having the structure shown in FIG. For comparison, a soundproof partition material was made using a corrugated sheet made of a flame-retardant board instead of the intermediate body of the honeycomb structure sheet-like material. And these two were used for the partition of the room and the sound insulation was compared. That is, the sound of 400 Hz and 800 Hz was transmitted from the speaker with a constant output, and the listening state of the sound in the adjacent room and the propagation state of the sound were struck by hitting the partition with a constant force. As a result, the samples of Examples were small in any sound and had excellent sound insulation. Further, it was also excellent in heat insulation. Example 2 High-Polymerization Polyvinyl Alcohol Fiber (Cut Strength 9.4g
/ dr, breaking elongation 8.5%) 360dr-24fil filament yarn and core-sheath type composite fiber 180dr-12fil consisting of 66 parts of 66-nylon as core component and 60 parts of ethylene-propylene copolymer as sheath component.
Using the twisted yarn obtained by twisting the filament yarn of No. 1, a knitted fabric with a mesh spacing of 3 mm is made by the Russell knitting method, immersed in a vinyl chloride resin emulsion solution, dried by tension heat treatment and core-sheath type composite fiber The sheet-like material obtained by causing the fusion of the sheath component polymer to fix the tissue is subjected to the press treatment in the same manner as in Example 1 to obtain the honeycomb-structure sheet-like material [III].
(The average elongation at the time of cutting was 4%). Flame retardant-treated cardboard was joined to both sides of this sheet-like material [III], and fusuma paper was further stretched to form a fusuma having a constitution as shown in FIG. This fusuma was lightweight, easy to open and close, had no squeaking noise, had a high morphological stability, and had durability.

である。The composite structure having the honeycomb structure sheet-like material of the present invention as an intermediate layer has a high air permeability and has little discomfort even when used for a long time. Further, it is a futon or mat which has little change in shape due to temperature, has appropriate hardness, body addition and cushioning properties, and has a high sense of stability. In addition, it is a lightweight fusuma, partition plate, and soundproof material that has excellent sound insulation and heat insulation properties and has low sound transmission.
