investigation of thermal comfort properties of woven sport fabric using blend of estabragh fibers
امروزه لباس در نظر ورزشکاران و کسانی که برای اوقات فراغت خود و یا برای رسیدن به اندامی متعادل، ورزش می کنند؛ بسیار با اهمیت است. احساس مطلوب از لباس در زمره خصوصیات راحتی پوشش می باشد. خصوصیات انتقال رطوبت لباس، در ارزیابی راحتی حسی و حرارتی منسوجات تولید شده از آن ها بسیار مهم است. هدف از این تحقیق، معرفی پارچه جدید است که متشکل از الیاف استبرق با خواص منحصر به فرد می باشد. استبرق لیف طبیعی تو...
Comparison of Acid-hydrolyzed and TEMPO-oxidized Nanocellulose for Reinforcing Alginate Fibers
Two samples of acid-hydrolyzed nanocellulose and two samples of TEMPO-oxidized nanocellulose were separately prepared from cotton liner pulp and microcrystalline cellulose, and dispersed in water. Sodium alginate that was extracted from brown seaweed was dissolved in the nanocellulose suspensions and wet spun in a calcium chloride bath to form four kinds of alginate/nanocellulose composite fibe...
متن کاملStructure and Properties of Cotton Fibers Modified with Titanium Sulfate and Urea under Hydrothermal Conditions
Cotton fibers were treated with titanium sulfate, urea and hexadecyl trimethyl ammonium bromide by low temperature hydrothermal method. The surface morphology, chemical structure, thermal stability and optical properties of cotton fibers before and after treatments were studied by scanning electron microscopy (SEM), transmission electron microscopy(TEM), Fourier transform infrared spectroscopy ...
متن کاملsome properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
15 صفحه اولTransitional Properties of Cotton Fibers from Cellulose I to Cellulose II Structure
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...
