To obtain a sheet capable of controlling the amount of passage of a fluid such as, to begin with wind, earth, water (including sea water) or their mixture, excellent in visibility of the sheet and endurance, also flexible, and having a good working efficiency by adopting a knitted or a woven structure obtained by arranging fiber groups A formed with slit state vacant spaces having a spacing of 0.5 mm or larger between adjacent fibers each other and fiber groups B as a lattice state, and having mesh state vacant spaces having widths of each 2 to 15 cm, and enclosed by the above fiber groups A and fiber groups B in an orientation direction of the fiber group A and in an orientation direction of the fiber group B

Sheet capable of controlling quantity of passing fluid

Pneumatic structure

A cushioning structure which is a three-dimensional multiple woven texture formed of a surface layer portion and an intermediate layer portion, characterized in that (i) protuberances are formed on one side or both sides of the surface layer portion at least unidirectionally and have an average height of 2 to 15 mm, an average width of one side of the protuberance being 2 to 30 mm; and that (ii) said intermediate layer portion is formed of one layer or by laminating two or more layers, said layer having a plurality of communicating hollow portions which are arranged in parallel unidirectionally. This cushioning structure is excellent in air permeability, cushioning properties, durability and washability, and is therefore useful as various cushioning materials.
