Filtration 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...
متن کاملHEK293S Cells Have Functional Retinoid Processing Machinery
Rhodopsin activation is measured by the early receptor current (ERC), a conformation-associated charge motion, in human embryonic kidney cells (HEK293S) expressing opsins. After rhodopsin bleaching in cells loaded with 11-cis-retinal, ERC signals recover in minutes and recurrently over a period of hours by simple dark adaptation, with no added chromophore. The purpose of this study is to invest...
متن کاملNonwovens Uniformity Spatial Characterization * Ji ř
The main aim of this contribution is comparison of method for evaluation of nonwovens surface uniformity based on the data in the form of rectangular arrays (quadrat method). These data can be obtained from digital images where the variation of mass is characterizes by the variation of grey level image. The evaluation of uniformity is based on the variation coefficient model, ANOVA model and sp...
