Color fastness is a very important indicator to evaluate the quality of textiles. At present, color fastness is tested mainly according to China National Standard (GB/T series) and American Association of Textile Chemists and Colorists (AATCC series). Different standards give different quality results for the same sample. The paper mainly compared the differences of color fastness to water, perspiration and rubbing between GB/T series and AATCC series. Color fastness to water tested according to GB/T5713-1997 was different from AATCC107-2007 in sample size, liner fabric, and time for keeping constant temperature with 4h and 18h, respectively. The differences of color fastness to perspiration of GB/T3922-1995 and AATCC15-2007 were sample size, liner fabric, component and pH value of perspiration, liquor ratio and time for keeping constant temperature. Of which pH value of perspiration showed remarkable difference, GB/T3922-1995 specified two kinds of perspiration with pH value 5.5 and 8.0,while AATCC15-2007 specified pH value with 4.3. Color fastness to crocking stands of GB/T3920-2008 and AATCC8-2007 had little difference, mainly in the moisture of rubbing fabric.

Shallots are one of the many types of plants available in Indonesia. Shallots are annual plants that can grow in the highlands and lowlands. In its use, shallots produce a lot of waste in the form of skin which can be processed into solid soap preparations because they contain antibacterial properties derived from flavonoid compounds. This study aims to produce solid soap onion skin extract and test the physical quality of the preparation according to the Indonesian National Standard (SNI). The research method was experimental which consisted of making simplicia and extracting it by maceration method using 70% ethanol as a solvent. Red onion peel extract formulations were used with a concentration of 5% (Formulation 2) and 0% (formulation 1) as the control basis. Evaluation of solid soap preparations includes organoleptic observation, homogeneity testing, foaming test, pH testing. The preparation was evaluated for 4 weeks at room temperature. Data were analyzed descriptively and compared with SNI. The results of this study indicate that the soap preparation is homogeneous, has a solid texture, is light brown (formulation 1), and dark brown (formulation 2).

Abstract The effect of different surface sizing formulations on the chemical features of surfaces of the papers produced from Eucalyptus kraft pulp was studied. The surface analysis techniques, electron spectroscopy for chemical analysis and time-of-flight secondary ion mass spectrometry were applied. An uncoated base paper, the reference material, was sized with blends of cationic starch with either co-acrylonitrile-acrylate or co-styrene-acrylate. The results of both techniques are in good agreement and complete each other. It was possible not only to detect the presence of the surface sizing agents on the paper surface but also to distinguish them and evaluate their distribution and relative concentration. In addition, it was found that application of higher amounts of the sizing formulations, at a constant ratio of 20% copolymer to starch, did not significantly change the chemical properties of the paper surfaces.

The aim of this study was to investigate the properties of hydrophobically modified (HM) quaterna-ry ammonium starch ethers for paper sizing. These starches possess temperature-responsive properties; that is, gelation or phase separation occurs at a certain temperature upon cooling. This insolubility of the HM starches in water at room temperature improved their performance as sizing agents. The contact angles for water on sized liner were substantially larger than on unsized liner. When the application temperature was well above the critical phase-separation temperature, larger contact angles were obtained for liner independently of pH compared with those at the lower application temperature. Cobb60 values for liner decreased upon surface sizing, with a low pH and high application temperature giving lower water penetration. Contact angles on greaseproof paper decreased upon sur-face sizing as compared to unsized greaseproof paper, independently of pH and temperature. Greaseproof paper showed no great difference between unsized substrates and substrates sized with HM starch at different pH. This is probably due to the already hydrophobic nature of greaseproof paper. However, the Cobb60 values increased at low pH and low application temperature. Surfactants were added to investigate how they affect the sized surface. Addition of surfactant reduces the contact angles, in spite of indications of complex formation.
