NON-WOVEN MATERIAL AND METHOD OF MAKING SUCH MATERIAL |
摘要 |
A non-woven material and method of formation thereof is provided to form a substantially flat or planar self supporting core of an inorganic base fiber and an organic binding fiber preferably using an air-laid forming head. In certain preferred embodiments, the non-woven material has a basis weight of about 3,000 gsm or greater. Preferably, the organic binding fiber has a binding component and a structural component within unitary fiber filaments. In one aspect, the structural component of the organic binding fiber has a composition effective to provide a strength thereof so that the non-woven material can be manually cut with minimal effort. In such form, the non-woven material is suitable to function as an acoustic ceiling tile. |
