SC CORA TRADING & SERVICE SRL - GOOD PRACTICE MODEL IN THE FIELD OF SUSTAINABLE DEVELOPMENT OF THE TEXTILE SECTOR

摘要

Awareness of the importance of reducing / slowing down, by any means, the level of pollution issteadily increasing and meeting this goal is an important objective at the level of the European Union. The useof natural resources is a measure that fits into this objective. SC Cora Trading & Service SRL is an example ofa 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 theprocessing, on the existing technology at SC Cora Trading & Service SRL, of a 100% fibrous fiber mixture forobtaining 4 unconventional textile structures for thermal and sound insulation in the constructions area. Thetechnological flow adopted consists of preliminary operations (sorting, cutting opening, willowing andblending), formation carded webs, cross lapped batts, 2 types of bonding operations (using steam and needlepunching) and final finishing operations. The steam bonded structures are bulky: (density: 36 kg/m3 to 54kg/m3), while the needle punching bonded ones are compact (density: 133 kg/m3 - 97kg/m3). The thermalconductivity of the obtained structures ranged from (0.0332 W/mK to 0.0392 W/mK), comparable to thermalinsulation materials from basaltic fibers and does not support burning.
