نُفِّذ في هذا العمل تشكيل ألياف نانومترية من البولي أميد 6,6 باستعمال تقنية الغزل الكهربائي. درسنا تأثير الجهد المطبق و قطر رأس الإبرة في مرفولوجيا الألياف المتشكلة (متوسط القطر، و الارتفاع و خشونة السطح)، و وصفنا الألياف الناتجة بواسطة المجهر الضوئي و مجهر القوى الذرية (AFM) و قد حصلنا على ألياف خطية، ملساء، طويلة و مستمرة و بأبعاد ، نانومترية، كما تبين أن أبعاد الألياف المتشكلة تناقصت بشكل واضح عند استخدام بارامترات معينة (جهد مطبق عالٍ، قطر رأس تشكيل صغير). هذا يقود بدوره إلى تحسين الخصائص الميكانيكية، و الفيزيائية و البيولوجيا للألياف المتشكلة، و تزيد من نشاطها الكيميائي، مما يزيد من إمكانية تطبيقها في تطوير وسائل الترشيح و تنقية المياه و منظومة الفلاتر و زيادة كفاءة عملها.
Nylon-6/6 continuous Polymer nanofibers (NF) were produced by using conventional single needle electrosprinng (ES) technique. In this paper several parameters, such as applied voltage and needle diameter were investigated to optimize fiber morphology. The morphological and structure properties of the fiber (average diameter, height, length, surface roughness and fiber shape) are visualized by Atomic Force Microscopy (AFM). Good alignment of polymer nanofibres was confirmed by AFM and optical microscopy observations. We concluded that fiber diameter increases with decreasing applied voltage intensity and increasing the distance between the electrodes.

In this study we used electro spinning technology to obtain
nonwoven webs of Nano fibers of poly vinyl alcohol and Nano
particles of silver . we dissolve the polymer poly vinyl alcohol in
it's solvent (water) to form a polymeric solution that we c
harged it
by positive charge and ejected it to leaving it on a collector that
we charged it by negative charge and used a high voltage. and
we mixed the polymer poly vinyl alcohol with silver nitrate with
different concentrations and electro spinning the mixture to obtain
Nano fibers and Nano particles of silver then we applied heat
treatment for the whole samples at 155°c for 5 minutes for tow
aims the first one is to make crosslinking between series of PVA
and the second is for the stability of silver nanoparticles , finally
we analyze samples on Scanning Electron Microscopy SEM .
Fattypolyamide was prepared by reaction of (1,5-Diamino pentane) with
dimeric fatty acid C36 in molten state. The reaction was performed at 110 C˚
without catalyst, then with (Phosphoric acid, Sulphoric acid and Manganese
dioxides). The Kinetic st
udy was carried out on the reaction and followed by
determining the acid value of the product. The polyamidation reaction was
found to be on the overall a second order up to 59% conversion. Then the
reaction order changes. We found that the Catalyst increases the velocity of the
reaction with manganese dioxides the best Catalyst. The Degree of
Polymerization, Number Average Molecular Weight and Weight Average
Molecular Weight have been calculated during different times. The
relationships between Degree of Polymerization and Number Average
Molecular Weight, Weight Average Molecular Weight with times are linear
until 59%conversion at 110˚C with used catalysts. The highest (N.A.M.W) and
(W.A.M.W) was accomplished with the Catalyst MnO2.
In this paper, we have used electrospinning technique to obtain nonwoven networks of nanofibers from polyacrylic nitrile, where we dissolved polyacryl nitrile in its dimethylformamide solvent to form the polymeric solution.
Due to the large and rapid increase in the demand for electricity and the gradual decline of
non-renewable sources of energy (fossil fuels, etc.), the performance of electrical systems
has to be developed so the use of distributed generation and it
s connection with the main
networks is one of these methods but this linkage causes some problems like changing in
electrical voltage.
In this research a radial electric distribution system was simulated and studied the effect of
distributed generation on electrical voltage stability -in static and dynamic state-and its
effect when the generator is synchronous or induction.
Yarn quality produced is essential to the economic success of
spinning plants. International competition and market requirements
dictate the necessity to produce quality yarns at an acceptable price.
