“…The film coated on the cellulose fibres by Na‐CMC gel has enhanced physical property of paper for printing purposes (Xiaojia et al , 2009). In textile industry, Na‐CMC is applied as a dye thickening agent (Fijan et al , 2009). In Detergent and surfactants, it is used as antidirt agent for protection of fibres surface (Mohanty et al , 2003).…”

Summary Na‐CMC or sodium carboxylmethyl cellulose is a water soluble anionic polymer obtained by introducing carboxymethyl groups along the cellulose chain. Na‐CMC is usually synthesized by the alkali catalyzed reaction of cellulose with monochloroacetic acid. The functional properties of Na‐CMC depend on the degree of substitution of the cellulose structure (i.e. how many of the hydroxyl groups are substituted per monomer unit), and also on the chain length of the cellulose backbone. The degree of substitution of Na‐CMC is usually determined according to ASTM D1439 which evolves the conversion of the Na‐CMC to free acid then again forming Na‐CMC by adding excess alkali and finally titrating the excess alkali with standard hydrochloric acid (0.3 N). The used volume of the standard alkali determines the degree of substitution. These existing chemical methods for determining the degree of substitution are not very convenient and very time‐consuming involving the use of hazardous chemicals. In this research, we have evaluated that the scanning electron microscope equipped with Energy Dispersive X‐Ray Analysis can be used to directly determine the degree of substitution.

“…In this study, only the final result of the equation of Friedrich-Braun model for oscillatory measurements of rheological properties of the material and biomaterial in the form of presented Equations (2) and (3) was determined. A similar procedure can be found in many papers on the characterisation of rheological properties of materials by means of this model (Fijan et al, 2007;Fijan et al, 2009;Oblonšek et al, 2003;Siddig et al, 2004;Sittikijyothin et al, 2005;Zupančič and Žumer, 2001). …”

This study was aimed at evaluating the possibility to use the Friedrich-Braun fractional derivative rheological model to assess the viscoelastic properties of xanthan gum with rice starch and sweet potato starch. The Friedrich-Braun fractional derivative rheological model allows to describe viscoelastic properties comprehensively, starting from the behaviour characteristic of purely viscous fluids to the behaviour corresponding to elastic solids. The Friedrich-Braun fractional derivative rheological model has one more virtue which distinguishes it from other models, it allows to determine the relationship between stress and strain and the impact of each of them on viscoelastic properties on the tested material. An analysis of the data described using the Friedrich-Braun fractional derivative rheological model allows to state that all the tested mixtures of starch with xanthan gum form macromolecular gels exhibiting behaviour typical of viscoelastic quasi-solid bodies. The Friedrich-Braun fractional derivative rheological model and 8 rheological parameters of this model allow to determine changes in the structure of the examined starch -xanthan gum mixtures. Similarly important is the possibility to find out the trend and changes going on in this structure as well as their causes.

“…Adanya kelemahan penggunaan alginat sebagai pengental pada textile printing karena viskositasnya yang rendah, stabilitasnya yang kurang baik maupun kecenderungan terjadinya pengendapan pada larutan dengan kandungan ion yang tinggi, medorong beberapa peneliti mencoba mencari alternatif pengental dari pati atau selulosa yang termodifikasi (Abdel-Halim et al, 2008;Tatongjai & Lumdubwong, 2010;Zhang et al, 2012), melakukan formulasi dari pengental sintetik (Ibrahim et al, 1994), menggunakan aplikasi surfactan (Fijan et al, 2007) atau mendaur ulang pengental yang sudah dipakai (Fijan et al, 2009). Gum sendiri seperti guar gum juga memiliki potensi digunakan sebagai pengental pada textile printing (Turk & Schneider 1998).…”

ABSTRAKPenelitian aplikasi campuran alginat dari Sargassum crassifolium dan gum untuk meningkatkan viskositas alginat sebagai pengental pada textile printing telah dilakukan. Viskositas campuran alginat dengan guar gum, gum arab, dan locust bean gum diamati pada penyimpanan selama 8 jam. Produk terbaik diujikan sebagai pengental pada textile printing. Campuran alginat dengan guar gum pada perbandingan 90:10 dan 80:20 meningkatkan viskositas dan stabilitas alginat selama penyimpanan. Campuran alginat dengan gum arab dan locust bean gum akan menurunkan viskositas alginat sehingga tidak sesuai untuk aplikasi textile printing. Aplikasi campuran alginat dengan guar gum 90:10 dan 80:20 sebagai pengental pada tekstil printing menghasilkan produk akhir yang setara dengan pengental komersial manutex.
