Abstract: Currently, packaging especially for food is a significant concern because made of plastic, which is difficult to degrade. Cellulose nanofibers (CNFs) as the composite reinforcement are chosen as a suitable replacement for the fiber. This nanocomposite is made with the main aim of making biodegradable food packaging with other capabilities such as antioxidant, antibacterial, etc. The food packaging was next referred to as bioplastic, consisting of several components. One of the major concerns is selecting cross-linking agents in nanocomposites production. The use of essential oil extracts from plants is widespread because it has an excellent binding ability and good chemical properties. The essential oil of orange peel can be extracted and used because it contains flavonoid compounds that act as antioxidants. The CNFs were made from palm oil empty fruit bunches (EFB) using the acid hydrolysis process in the previous research. The study of this nanocomposites production successfully makes transparent bioplastic. SEM results show a surface with fewer pores filled with cellulose fiber and protein. The addition of essential oil to the film increases the cross-linking bond in the matrix, improving its mechanical properties. The bioplastic was tested its endurance when buried in soil for 6 days and showed a promising results.

Abstract: Rabbit hair is a kind of animal hair, containing a large amount of keratin which can be extracted. According to the preparation method of wool protein powder, rabbit hair powder was obtained, and the morphology of the protein powder was observed by microscopy. By reacting with the alkali solution, two kinds of protein powders which were prepared from rabbit hair and wool, were used in modification of polyester fabric. Experimental results showed that samples with rabbit hair protein powder has evident improvement in moisture absorption of polyester fabric compared with untreated and wool powder treated samples, while UV protective properties of sample treated by rabbit hair powder was unexpected decreased, a further investigation will carry out to explain it.

Abstract: Rabbit hair is an important animal fiber in China, making up 90% of the total output in the world. Fuds is one of familiar problems in the processing of rabbit hair, which lead to plenty of waste fibers. Recently, there has been interest in converting protein fibers into powder to develop their new uses. This provides great opportunities for waste rabbit hair. In this study, rabbit hair powders have been produced and the structure and properties were characterized at multi-level. Surface morphology of rabbit hair powders was observed by scanning electron microscopy (SEM) and the majority of rabbit hair powders appear to be small fibrous particles. The FTIR spectrum of rabbit hair and rabbit hair powders was detected. Although no new chemical bonds were produced in the rabbit hair powders, the result showed that some absorbing peaks of rabbit hair powder become stronger than that of rabbit hair. Absorption of rabbit hair powders was also investigated. The result showed that rabbit hair powder had higher moisture retention rate than that of rabbit hair, wool fiber and cotton fiber. Moreover, rabbit hair powder showed remarkable sorption ability for metal ions. The characterization of rabbit hair powder will provide useful basal data for the further application of rabbit hair in novel areas.
