"Investigation of pumice stone powder coating of multilayer surfaces in relation to acoustic and thermal insulation". Journal of Industrial Textiles, 44(4), 639-661.1528-0837https://doi.org/10.1177/1528083713516665https://journals.sagepub.com/doi/10.1177/1528083713516665http://hdl.handle.net/11452/34535In this study, production of multilayer surfaces for acoustic and thermal insulation was investigated. After the optimum textile materials had been chosen to provide acoustic and thermal insulation, surfaces were created using different relative methods in this field. Sublayer nonwoven produced from slotted polyester fiber was combined with two different top layers of fabrics, one of which was the top layer of fabric woven from plain weave obtained from texture yarns, which, in turn, was produced from hollow polypropylene, and the other was plain weave obtained from texture weft yarn, which was produced from conventional polypropylene fibers separately. Subsequently, these two different surfaces were combined with polyurethane-based material. Pumice stone powder in three different concentrations and two different sizes was added to enhance acoustic and thermal insulation, after which the sublayer had been coated with an adhesive material to produce multilayer adhesive force and adherence to the wall. Consequently, air permeability, sound absorption, and thermal conductivity coefficients of multilayer surfaces were researched with regard to the type of top layer of fabrics, concentration, and particle size of pumice stone powder. The results demonstrate that the properties of multilayer surfaces concerning acoustic and thermal insulation increase with the increasing concentration of pumice stone powder and with the decreasing sizes of pumice stone particles. In addition, air permeability of multilayer surfaces was ensued to decrease with the increasing concentration as well as particle size of pumice stone powder.eninfo:eu-repo/semantics/openAccessMaterials scienceAcoustic insulationAdhesionAir permeabilityThermal insulationPumice stoneCompositesFibersConductivityPolyesterFabricsWasteAcoustic wave absorptionMultilayersParticle sizePolypropylenesPowder coatingsPowdersSound insulating materialsSound insulationTexturesThermal conductivityWeavingYarnAdhesive materialsConventional polypropylenesMultilayer surfacesPolyester fiberPumice stonesSound absorptionTextile materialsThermal conductivity coefficientThermal insulationArticle0003465744000092-s2.0-84919462032639661444Materials science, textilesSound transmission; Sound insulating materials; Biot theory
