Mechanical Property of Silk/Bamboo Composite Paper for Effective Utilization of Waste Silk

Abstract

Waste silk fiber is an important by-product in silk industry. In order to perform the efficient recycling of this waste silk resource, the papermaking technology was adopted, and silk/bamboo paper was produced. Beating treatment of fibers and chemical modification of silk fibroin fiber by epoxy reagent were carried out. The study of mechanical property, morphology and FT-IR spectrum showed that beating treatment could realize fibrillation of fibroin fibers effectively, however the strength of composite papers was rather weak. Proper beating treatment and modification still need to improve the mechanical property of the silk/bamboo hybrid paper.

Multiscale Hybridization of Natural Silk–Nanocellulose Fibrous Composites With Exceptional Mechanical Properties

“…Fibrous and fiber preform composites, which are produced by using natural SF as raw material, consist of SFs and additional chemical binders that increase the bonding between the SFs (Song et al, 2009;Yuan et al, 2010;Shubhra et al, 2011;Guang et al, 2015). Their mechanical properties greatly depend on the interaction between the binder and fibers.…”

“…Various natural raw materials can be obtained from such a complex hierarchical structure of woody biomass (Klemm et al, 2005(Klemm et al, , 2011Cervin et al, 2013). Such raw materials have been used to manufacture paper, (Song et al, 2009) pulp, (Theng et al, 2015) and fiber, which greatly contributed to human development. Recently, the development of advanced materials using nanocellulose has been actively attempted because of the robust physicomechanical properties of nanocellulose, which are based on its unique morphology and crystalline structure (Theng et al, 2015;Amini et al, 2017;Saba et al, 2017b,a;Tayeb et al, 2018;Feng et al, 2019;Kwak et al, 2019b).…”

Microstructure Transitions and Dry-Wet Spinnability of Silk Fibroin Protein from Waste Silk Quilt

“…Since silk fibroin has the extraordinary characteristics mentioned above and is expensive due to a complex production process and high market demands, besides, using silk fabrics wastes may decrease breeding of silkworms, many scholars have carried out research related to the recycling and reuse of silk. To more effectively recycle and reuse waste silk, certain scientists treated waste silk by impregnation and melting without damaging the internal molecular composition to prepare composites [33,34,35,36]. Certain researchers found methods to destroy the molecular structure of waste silk by high temperature and high pressure or chemical reagent treatment, and successfully obtained silk sericin or fibroin protein [37,38].…”

Effect of PVA Binder on the Mechanical Properties of Silk/Bamboo Paper-Reinforced PBS Green Composite

“…The PVA fiber was mixed with 5 min beaten silk fiber and bamboo pulp, and was then made into paper at room temperature using the papermaking method [12]. A 1 : 1 weight ratio between silk and bamboo fibers was maintained throughout the study.…”
