Yasunaga","doi":"10.2115/fiberst.2022-0006","DOIUrl":"https://doi.org/10.2115/fiberst.2022-0006","url":null,"abstract":": The wool fabrics were treated with VOSO 4 aqueous solution and its photothermal conversion and heat retention behaviours were evaluated in comparison with the fabrics of untreated wool, normal polyester and polyester incorporated with zirconium carbide. The adsorption of vanadium ions onto the wool fabric was found to be the Langmuir type. The VOSO 4 -treated wool fabric showed higher photothermal conversion than the untreated wool fabric, when it was irradiated with the visible/IR light. The temperature of the VOSO 4 treated wool single fabric under the light irradiation decreased slightly with an increase in the chamber humidity. The temperature of the single fabric after the light off increased largely with an increase in the chamber humidity. It was considered to be due to the increasing specific heat capacity of the fibre which absorbed and adsorbed water. The surface temperatures of the lighted side and of the back of the lighted side for the four-layered VOSO 4 -treated wool fabrics were highest among the fabrics of untreated wool, normal polyester and polyester incorporated with zirconium carbide, when they were irradiated with the light at 65 % RH humidity. It was found that the VOSO 4 -treated fabric is the warmest on the whole, when the same light is irradiated to the four kinds of layered fabrics.","PeriodicalId":54299,"journal":{"name":"Journal of Fiber Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67639315","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is important to determine from which bird down was taken because the quality and price of down vary greatly depending on the bird species. In this study, infrared spectroscopy instead of the conventional microscopic observation was used to identify the bird species from which down was obtained. Goose down and duck down could be accurately identified by selecting an appropriate wavenumber region of the infrared (IR) absorption spectrum obtained using the attenuated total reflection (ATR) method and the partial least squares discriminant analysis (PLS-DA) method. Score plots based on principal component analysis (PCA) were found to be effective for identifying eider duck down and non-eider duck down.","PeriodicalId":54299,"journal":{"name":"Journal of Fiber Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67638869","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the natural polysaccharides, chitin, comprising main chains of β(1 →4)-linked N -acetyl-D-glucosamine (GlcNAc) residues, is an important biomass resource because it is one of the most abundant polysaccharides present in nature, mainly prevalent in the exoskeletons of crustaceans [2‒4]. However, chitin remains largely underutilized because of its poor solubility and processability, owing to its intractable bulk structure composed of numerous intraand inter-molecular hydrogen bonds. The fabrication of nanoscale polymeric assemblies (e.g., nanofibers and nanowhiskers) is a useful method for the functionalization of chitin [5‒7] because of the remarkable properties of bio-based nanomaterials, such as low weight, high tensile strength, and biocompatibility [8‒14]. Efficient procedures for the preparation of chitin nanofibers (ChNFs) and nanowhiskers have been developed using a top-down approach that breaks down the starting bulk materials from native chitin sources [5, 6, 15‒18]. Based on another approach‒the bottom-up technique‒we previously developed a facile method to fabricate ChNFs with a width of approximately 20‒60 nm and length of several hundred nanometers. Selfassembling regeneration at the nanoscale from an ion gel of a chitin/ionic liquid, namely, 1-allyl-3methylimidazolium bromide (AMIMBr), was achieved using methanol [19, 20]. This was based on our previous findings that AMIMBr efficiently dissolves and swells chitin [21]. Isolation of the resulting ChNFs from the methanol dispersion via filtration produced a ChNF film possessing a heavily entangled nanofiber morphology. Furthermore, the self-assembled ChNFs had a bundle-like structure consisting of an assembly of thinner fibrils [22]. The treatment of the ChNF film with an aqueous NaOH induced the partial generation of amino groups on the chitin chains (i.e., partially deacetylated chitin nanofibers (PDA-ChNFs)). This led to the successful disentanglement of the bundles by cationization and electrostatic repulsion in 1.0 mol/L aqueous acetic acid with ultrasonication, yielding 【Transaction】","PeriodicalId":54299,"journal":{"name":"Journal of Fiber Science and Technology","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67639348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
