The invention relates to technology of production of non-woven materials and can be used for production of building finishing and other like materials. A needle-punched material has first and second layers of nonwoven fabric arranged as fibrous webs, fibers in which are directed along and across the material, net of glass threads that is placed between the fiber, and binding agent. Layers of fabric are fixed with fibers that form fibrous webs to pack together with net as result of needle-punching. Fibrous webs and net form bound pack in which mechanical characteristics along the pack and across it are essentially close. Due to that one obtains comparatively low-cost material that has high enough technical characteristics, this makes possible its different use in corresponding segment. |
