Abstract Alginate is an interesting natural biopolymer for many of its merits and good biological properties. This paper investigates the electrospinning sodium alginate (NaAlg), NaAlg/PVA‐ NaAlg/PEO‐ blended systems. It was found in this research that although NaAlg can easily be dissolved water, aqueous solution could not electrospun into ultrafine nanofibers. To overcome poor electrospinnability solution, synthetic polymers such as PEO PVA solutions were with to improve spinnability. The...

Protruding yarns influence a fabric's properties and its end use. This paper discusses new approach to measuring fabric appearance objectively using image processing techniques by Fourier transform analysis. Characteristics of the surface such as directionality, density protruding from body, periodicity weft warp yams (yarn spacing) for plain-weave cotton are discussed. The yarn obtained in this study correlates with those previous work spectral analysis dynamic friction surface. is regarded...
