A synthetic fibre from polyolefins wastes was obtained as follow:
1. From polyethylene and polypropylene wastes in various
percentages to get the optimum percentage in the fibre
2.From polyethylene and polypropylene gralunar.
We used an indirect
recycling operation using extrusion by the
extruder.
The obtained fibre was tested mechanically, physically and
chemically and the results demonstrate that the production of these
fibers are available laboratorially and industrially.
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.
