Flax (Linum usitatissimum L.) is an annual plant cultivated mainly for its fibres. Although the whole genus contains about 230 species, only L. usitatissimum retains an important commercial use, serving as a fibre source for the textile industry. Flax fibres are less elastic than cotton fibres, and thus their use in textile production is more limited. However, the climate and soil quality in ce...
امروزه، تحقیقات و طرح های توسعه صنعتی در زمینه بیوتکنولوژی و حفظ محیط زیست از اهمیت خاصی برخوردار گردیده و استفاده از امکانات موجود در طبیعت توجه محققین را به خود جلب کرده است. از جمله این موارد، استفاده بهینه از مواد سلولزی و لیگنوسلولزی است. امروزه، استفاده از الیاف طبیعی گیاهی، علاوه بر صنعت نساجی در صنایع پلیمری و خودروسازی از اهمیت خاصی برخوردار شده است. توسعه روز افزون کاربرد الیاف طبیع...
Reactive dyes have been used in the textile industry for the past 60 years; they colour fibres brightly and are highly wetfast. They consist of a direct colourant (an azo, anthraquinone or phthalocyanin derivative group) connected to a reactive group, which is capable of linking through covalent bonds to the amine or sulfhydryl groups of proteins (1). We report a case of a delayed contact hyper...
برای پیش بینی رفتار منسوج در حین مصرف, آگاهی از خواص مکانیکی آن ضروری می باشد. ساده ترین راه مطالعه خواص مکانیکی بصورت عملی کشش یک محوری است. در این تحقیق ارتباط بین خواص مکانیکی پارچه های حلقوی تاری شامل افت تنش, مدول, ضریب پواسون وکشسانی با تغییرات ساختمانی پارچه شامل طول آندرلپ در شانه های جلو و عقب و همچنین تراکم پارچه مورد بررسی قرار گرفته اند. در این تحقیق پارچه ها بر مبنای افزایش در طو...
Abstract Bicomponent regenerated cellulose fibres (bRCF) have been created in a core–shell configuration from waste textiles. Textile dyeing and colouration is known to be major contributor the environmental impact of producing textiles this needs addressed for become more sustainable. Coloration bRCF here was achieved by utilizing coloured textile shell component whilst using white cotton core...
Researches in the field of conductive polymers have attracted considerable attention for more then 20 years. Among the conductive polymers, polyaniline and polypyrrole have drawn considerable interest because of their economical importance, good environmental stability and satisfactory electrical conductivity when doped. On the other hand, electrically conductive materials such as aluminium pow...
Moss, E. and Lee, W. R. (1974). British Journal of Industrial Medicine, 31, 224-232. Occurrence of oral and pharyngeal cancers in textile workers. The occupations of male textile workers who died of oral and pharyngeal cancers in the five years 1959-63 have been examined to discover whether the high incidence of oral cancer in these workers noted by the Office of Population Censuses and Surveys...
The spread of HIV and hepatitis viruses by contact of contaminated materials has created increased pressure for protection of personnel with functional clothing; also, all articles of apparel and home textiles are susceptible to problems of hygiene in normal daily use, for example, socks, sport wear and working clothes as well as mattresses, floor coverings, and shoe linings. Textiles for outdo...
