Textile fibers have become a major issue in the debate on sustainable fashion and clothing consumption. While consumers are encouraged to choose more circular textile materials, studies indicated that reduction production consumption has greatest potential reduce total environmental impact. This can be considered an ecocentric perspective with focus degrowth as opposed technocentric view where ...
Background; The Textile production industry is one of the most precious technologically complex all industries because variety substrates, processes, machinery, and components used finishing steps undertaken. Aim objectives: was to compare effect maternal exposure natural fibers synthetic in textiles among women textile workers, on pregnancy outcomes, at Misr Spinning Weaving Company El Mahalla...
The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...
Escherichia coli (E. coli) was used to activate hydrolysis reaction along with biodegradation in natural and synthetic fibers to identify possibilities as alternative substitutes for textile wastes using chemical solutions and enzymes. To confirm the reaction between the bacterial infections of E. coli and the excessively abundant interstitial spaces of the fibers, various types of natural and ...
This thesis examines the capability of current techniques in fiber classification such as UV-visible microspectrophotometry (MSP) (for dye in situ and/or extracted) to discriminate between fibers from sources known to be different. When these methods fail to adequately distinguish the fibers, novel alternative techniques, such as pulsed pumped laser-induced fluorescence spectroscopy (LIF) and l...
As landfill costs rise, so does the pressure to increase recycling of nonhazardous waste. A study was conducted to determine the attitudes of textile manufacturers towards market acceptance of recycling textile fibers into new textile products. A questionnaire elicited responses from 90 of 157 manufacturers in seven textile Standard Industrial Codes (SICS) in North Carolina, including small, me...
هدف اصلی از انجام این تحقیق ، بررسی کیفی رفتار شیب دو طرفه ماسه مسلح شده با تریشه موکت و مقایسه آن با نتایج آزمایش های مشابه بر روی ماسه غیر مسلح در دستگاه میز لرزه دستی که جهت همین موضوع طراحی و ساخته شده است می باشد.جهت تهیه مصالح مصرفی ساخت این مدل ،از نوعی خاک مسلح که از اختلاط ماسه 161 فیروزکوه با تریشه موکت که بصورت تصادفی توزیع می گردند ،استفاده می گردد. بنابراین برای تحقق هدف مورد نظر...
Textile materials made from natural fibers have played an important role in the life of human beings from time immemorial and still are widely used in the modern textiles industry for their unique properties as high quality tex tile materials. Due to the variation in staple length, the natural fibers with short staple length can’t be used to spin yarns. Consequently, natural fibers such as wool...
Textile composites describe a broad range of polymer composite materials with textile reinforcements, from woven and non-crimp commodity fabrics to three dimensional textiles. In a general manner textile composites are based on textile preforms manufactured by some textile processing technique and on some resin infiltration and consolidation technique. Due to the complex three-dimensional struc...
