| description | Awareness of the importance of reducing / slowing down, by any means, the level of pollution is steadily increasing and meeting this goal is an important objective at the level of the European Union. The use of natural resources is a measure that fits into this objective. SC Cora Trading & Service SRL is an example of a Romanian company focusing on the use of small and medium fineness sheared, tannery and recovered / recycled wool fibers in high value added products. The paper presents experimental results regarding the processing, on the existing technology at SC Cora Trading & Service SRL, of a 100% fibrous fiber mixture for obtaining 4 unconventional textile structures for thermal and sound insulation in the constructions area. The technological flow adopted consists of preliminary operations (sorting, cutting opening, willowing and blending), formation carded webs, cross lapped batts, 2 types of bonding operations (using steam and needle punching) and final finishing operations. The steam bonded structures are bulky: (density: 36 kg/m3 to 54 kg/m3), while the needle punching bonded ones are compact (density: 133 kg/m3 - 97kg/m3). The thermal conductivity of the obtained structures ranged from (0.0332 W/mK to 0.0392 W/mK), comparable to thermal insulation materials from basaltic fibers and does not support burning. |
