Air Permeability and Acoustic Absorbing Behavior of Nonwovens
Abstract: Several nonwovens were studied to explore the relationship between their structural characteristics, permeability and acoustic absorbing behavior. Fundamental structural parameters including thickness, gram square meter and porosity were considered. Results show that the permeability is not just linear to porosity, but also related to many other complex and difficult-to-measure parame...
متن کاملFiltration properties of nonwovens.
This paper presents the results and conclusions from experimental investigations concerning filtration properties of nonwovens. The needled nonwovens were made from polyester fibres (PTE) with average fibre diameter 12 micrometres and polypropylene fibres (PP) with average fibre diameter 32 micrometres. Nonwovens were produced out of each of those fibres or out of a mixture of polyester and pol...
متن کاملNanoclay Reinforced Fibers and Nonwovens
In this research, polypropylene fibers and nonwoven samples were produced with the commercial samples of nanoclay additives in semi-commercial processing machinery. Influence of two different types of nanoclay additives, at different add on levels on processing, structure and morphology of nonwovens is studied. The WAXD and DSC data showed some change in crystallinity and melting behavior indic...
متن کاملInternational Nonwovens Journal Home Page
The physical characteristics and performance attributes of absorbent gauze and spunlaced nonwovens used formedical/surgical applications are reviewed. Because the manufacturing lines for spunlacing are versatile and highlyproductive, nonwoven products from this process are highly engineered and may have superior performancecharacteristics relative to gauze products. Dressings ma...
