The effects of fabric parameters and initial moisture content in dryer on the smoothness appearance of woven cotton fabrics have been determined. In this study, 11 kinds of cotton fabrics were selected to evaluate their smoothness appearance after drum drying. The results indicated that the fabric parameters---surface density, thickness and warp density--- had a certain correlation with the fabric smoothness appearance, which wasn’t significant. The initial moisture content affected smoothness appearance positively. With the increasing of initial moisture content, the grade improved and the difference between the max and the mini is about 0.5grade. This study can provide a reference for the design of the dryer program and make fabric washing process achieve the coordination with drying process to obtain a best fabric appearance.

Palladium nanoparticles (Pd NPs) are the most widely used functional materials for a variety of catalytic reactions. In this work, we synthesized the size-controlled Pd NPs using amyloid fibrils as bio-templates. First, 1mg/ml insulin peptides were incubated at 80°Cfor 3 days to form protein fibrils. Then, layer-by-layer technology was used to prepare Pd-insulin fibrils multilayer film as catalyst by alternatively depositing insulin fibrils and palladium chloride which has been aged at several different temperatures for two days. The chemical compositions of Pd-insulin film were also characterized by X-ray photoelectron spectroscopy (XPS). The Pd-insulin film demonstrated high isolated yield in promoting Suzuki cross-coupling reaction. In addition, the effect of Pd NPs size on the catalytic activity was also discussed.
