In recent years, domestic and foreign research on smart fibers textiles has achieved many results, been increasingly widely used in the textile field. This article introduces functions of main seven types fibers, as well a brief description shape memory textiles, color-changing temperature control waterproof moisture-permeable self-cleaning electronic information textiles. At present, are mainl...
Ceramic nanofibers (NFs) have recently been developed for advanced applications due to their unique properties. In this article, we review developments in electrospun ceramic NFs with regard to their fabrication process, properties, and applications. We find that surface activity of electrospun ceramic NFs is improved by post pyrolysis, hydrothermal, and carbothermal processes. Also, when combi...
در کار حاضر از الیاف منقطع پلی پروپیلن و اکریپیک جمع شونده استفاده گردیده است. از مخلوط الیاف مذکور پارچه های بی بافت سوزن زنی شده تولید گردید و بخشی از تولیدات تحت فرایند شستشو با آب جوش و دتر جنت (از نوع ریکا) قرار گرفت. پس از شرایط آماده سازی، خواص فیزیکی پارچه ها اندازه گیری شد. این خواص عبارتند از:خواص مکانیکی (ازدیاد طول تا پارگی، استحکام پارگی و طول خمش) ضخامت، وزن واحد سطح، قابلیت نفوذ ...
در طی فرایند پیچش، هنگامی که نخ از دیسک کشش دهنده، راهنمای نخ و درام شیاردار عبور می کند، الیاف واقع در سطح نخ، سائیده شده که باعث تغییر در پرزینگی نخ می شود. کاهش پرزینگی نخ در طی فرایند پیچش با استفاده از جت های هوا، یک روش جدید است، به دلیل اینکه سرعت تولید در مرحله پیچش خیلی بالا بوده و خود فرایند باعث افزایش پرزینگی می شود. در این تکنیک، جریان هوای داخل جت، انتهای الیاف بیرون زده را به دو...
Plasmonic nanoparticles (NPs) such as silver and gold have fascinating optical properties due to their enhanced optical sensitivity at a wavelength corresponding to their surface plasmon resonance (SPR) absorption. Present work deals with the fabrication of silver nanoparticles decorated cotton (SNDC) fibers as a cheap and efficient point of contact disinfectant. SNDC fibers were fabricated by ...
Mercerized fibers were prepared from native cotton fabrics via NaOH solution treatment at different concentrations. Mercerization led to transformation of the crystal structure of cotton fibers from cellulose I to II when the NaOH concentration was greater than 10 wt%. In addition, the cotton fibers were converted into a swollen and rough state after mercerization treatment. The results of Four...
This mini-review aims at strengthening the links among textile science, physics, and mathematics. The state-of-the-art technology for silver ions’ release from hollow fibers is reviewed, its bottleneck problems are identified, some open elucidated. oscillation opens a new era modern applications of containing ions.
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...
