FIELD: textiles, paper.SUBSTANCE: non-woven fabric and method of its formation provide for the formation of generally flat or plain self-supporting core of inorganic base fiber and organic binding fiber, preferably using an aerodynamic web-forming head. In some preferred versions, the organic base fiber has the fiber strength with the rupture load of about 10 g or less and an elongation of about 20 percent or less. Preferably, the organic binding fiber has a binding component and a structural component in single fiber filaments. In one aspect, the structural component of the organic binding fiber has a composition effective to ensure its strength, thus, a non-woven fabric can be cut manually with minimal effort.EFFECT: in this form the non-woven fabric is suitable to act as an acoustic ceiling plate.10 cl, 2 dwg |
