Characterization of cellulose nanofiber sheets from different refining processes, Kohji Nobuta et al , Cellulose , 23 (1). Four types of kenaf bast fibres were prepared via a combination of treatments for delignification and alkaline treatments, for the removal of hemicellulose. Each type of kenaf bast fibre with different refining processes were nano- fibrillated by grinding. NONWOVENS 3D-oriented fiber networks made by foam forming, Majid Alimadadi & Tetsu Uesaka, Cellulose , 23 (1). In industrial applications, such as paper and nonwovens, cellulose fibres are used in the form of a network where the fibres are oriented more or less in the sheet- plane direction. However, in many biological systems, fibres are instead oriented in three- dimensional (3D) space, creating a wide variety of functionalities. In this study researchers created a 3D-oriented fibre network on the laboratory scale and have identified some unique features of its structure and mechanical properties. Hybrid adsorbent nonwoven structures: a review of current technologies, Hooman Amid et al , Journal of Materials Science , 51 (9). Adsorptive nonwoven substrates are composite media that contain adsorbent materials within their fibrous structure; the methods to incorporate adsorbents in nonwoven webs determine their adsorption capacity. The key objective for hybridisation is to immobilise the adsorbent while controlling the packing density and pressure drop of the composite media. The primary focus of this review is on hybridisation techniques that incorporate activated carbons and/or metal- organic frameworks in nonwoven structures, used in gas filtration. NOVEL PAPER PRODUCTS Large scale preparation of graphene oxide/cellulose paper with improved mechanical performance and gas barrier properties by conventional papermaking method, Quanbo Huanga et al , Industrial Crops and Products , 85. Graphene oxide (GO)/cellulose paper was prepared by adding aqueous dispersion of GO into cellulose fibre pulp in a traditional papermaking procedure. Cationic polyacrylamide (CPAM) was added as a mordant to induce the self-assembly of GO layers on the fibre surfaces. The surface morphology, mechanical properties and gas permeability of GO/cellulose paper with varying GO contents were investigated. The large scale preparation of GO/cellulose paper with high doping amount of GO, which exhibited dense and compact geometry and low gas permeability, is ideal for potential packaging applications. Study on the Printing Quality Comprehensive Evaluation of Color Inkjet Paper, Xiaoxiu Hao et al , in Proceedings of the 2015 International Conference on Advanced Material Engineering , Chapter 2: Materials Process Engineering. The coating of inkjet paper can not only prevent the ink to the bottom, but also control the spread and thickness of the ink particles, which influence the printing definition. So the coating formulation of inkjet paper directly affects the quality of printed matter. Six kinds of inkjet papers from different companies were selected for experiment, and then their various printing quality parameters were compared. Experimental results showed that the parameters such as dot gain, printing colour density, relative contrast and ink absorbency could synthetically evaluate the printing quality of inkjet paper. The data could provide the theoretical basis for quality control of inkjet paper. Furthermore they have a strong guiding effect on the actual production of inkjet paper.
