ينتج عن أنظمة الغزل الحلقي و التوربيني و الهوائي خيوط مختلفة الخصائص و البنية بحيث يمتلك كل نظام حدوداً و تفاوتات خاصة من حيث الجدوى الفنية عند استخدامه و قابلية تطبيقه من الناحية الاقتصادية. و لإجراء المقارنة بين هذه الأنظمة أُْنتجت خيوط بنمرة 30Ne و بتركيب قطن 100 % و ذلك باستخدام الأنظمة المذكورة سابقاً و من ثم حيكت هذه الخيوط على آلة التريكو نوع سنكل جورسيه. وجد في أثناء عملية الغزل تقطعات متكررة في خيوط الغزل التوربيني في أثناء تشغيلها و بالمقارنة وجد أن خيوط الغزل الحلقي و خيوط الغزل الهوائي تملك أداء جيداً في أثناء تشغيلها على آلة الحياكة.
Ring, Rotor(O.E) and Air vortex spinning systems provide yarns with different structures and properties. Each system has its limitations and advantages in terms of technical feasibility and economic viabilit y Ne 30, 100%cotton yarns were produced from the above systems and knitted in single jersey machine .The Rotor Spun yarns found with frequent breakage during knitting.

In this research, artificial neural networks, one of the most common branches of artificial
intelligence, were used to evaluate the diameter of the cotton yarn. The necessary data
were collected and practical tests were carried out. Then, an algori
thm for the artificial
neural network was established, which provides the possibility of determining the yarn
diameter from the input variables, represented by the count and twist yarn. Where after
the creation of many networks, one was selected which gave the lowest error rate.
research The aim of this is to find an explicit relationship between the strength of fibers, bundle and
yarns. The CV values of the strength are given as well. This provides a relatively simple method for
estimation of staple yarn strength, while a
voiding some difficulties of an empirical method. The effects of
important factors such as fiber length and thickness, twist and count of yarn are considered. The results
are verified by published data in Mechanical Engineering of Textile Industries and Their Technologies,
Faculty of Mechanical and Electrical Engineering, Damascus University. and also in Al-Kumasiah
company in Damascus city.
This research provides suggestions if we apply it it will help in estimating directly the yarn strength
without manufacturing and suitable testing of the yarn.
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.
The majority of known polymer materials are electrically insulating.
But there are some of polymers are intrinsically conducting in
nature, However, it is lacking in process ability, and the scope for
manipulation of electrical and mechanical prop
erties is limited. The
method which used to solve this problem is an addition of a
conductive metal filament into a polymer filament yarn. Which can
be directly integrated into a textile, or can be knitted. So we made
a device able to produce this kind of conductive yarns which
depends on melt spinning technique but with the elimination of
necessary pressure for extrusion. And we were able to produce
samples of copper filament coated with polymeric material (low
density polyethylene).
