“…On the other hand, protein powder could keep the original properties of materials without destroying the microstructure. Hence, it has been widely applied in modern industries and hi-tech related fields with various special properties (Novak et al, 2004;Zhang et al, 2001;Miyajima et al, 2001).…”

Fibers based regenerated protein draw much attention for recycling discarded protein resources and can produce biodegradable and environmental friendly polymers. In this study, superfine wool powder is blended with polypropylene (PP) to produce wool powder/PP blend film through extrusion and hot-pressing. Hydrogen peroxide is used to bleach the black colored surface of the blend films. The effects of peroxide concentration, bleaching time and powder content on the final whiteness and mechanical properties of the blend films are investigated.The bleached films are dyed with acid red dyes and the dyed color is evaluated using a Computer Color Matching System. Color characters of dyed films, such as L * , a * , b*, ∆E * ab, C*ab and K/S values are measured and analyzed. The study not only reuses discarded wool resources into organic powder, widens the application of superfine wool powder on polymers, but also improves the dyeing properties of PP through the addition of protein content.

“…On the other hand, since the protein powder could keep the original properties of the materials without destroying the microstructure, it has been widely applied in modern industries and some hi-tech related fields due to some of its special properties. [7][8][9] Silk powder was produced as one of the useful physical forms of silk fibroin protein which had some special properties compared with the fiber and silk films for biomaterial applications. [10,11] It has also been applied to the finished yarn-dyed cotton fabrics to offer good drape characteristics and moisture absorbing properties.…”

Superfine wool powder was blended and extruded with poly(propylene) (PP) to produce blend pellets, and the extruded pellets were hot‐pressed into a blend film. SEM photographs show that the powder could be uniformly incorporated with PP after extrusion. FT‐IR spectra shows that no substantial changes occurred in the chemical structure of both PP and wool powder in the blend film. X‐Ray diffraction analysis indicates that crystallinity of the blend film was much higher than that of the wool powder and little lower than that of PP. TG‐tested results indicate that the thermal stability of the blend film declined with an increase in the powder content. Endothermic peaks of the wool powder in the blend film become more obvious as the powder content increases. Mechanical properties decline greatly with an increase in the wool powder content in the blend film.magnified image

To manufacture the hygroscopic sheets available for functional application, superfine down powder (SDP) and stearic acid modified superfine down powder (MSDP) were, respectively, blended and extruded with polypropylene (PP) to produce composite pellets, and the extruded pellets were hot-pressed into composite sheets. The chemical reaction between SDP and stearic acid was characterized using the attenuated total reflection attachment on the Fourier transform infrared. PP/MSDP composites showed more uniform powder dispersion in PP matrix, higher compatibility, and better mechanical properties than that of PP/SDP composites, which showed an evident decrease in tensile strength and elongation at break compared with pure PP. It was worth noting that the Young's modulus of PP/SDP composites was higher than that of pure PP, but lower than that of PP/MSDP composites. The addition of SDP led to a large increase in water absorption of PP/SDP composites. However, the water absorption of PP/MSDP composites decreased slightly compared with that of PP/SDP composites. Furthermore, the effects of SDP and MSDP on the microstructural and thermal properties of different composites were also investigated, respectively.
