In this research, we did the optical spectral study for using
ultrasound energy in dyeing wool fibers using acid dyes. That we
dyed wool fibers using both traditional dyeing and ultrasound
techniques by using three acid dyes from different firms.
The results of exhaustion percentage of the dye had been compared "the total moving dyes from a solution to fibers after dyeing".
The exhaustion rate of some dyes increased by a large proportion
but the effect on the fastness of the light, rubbing and washing was not great.
In this research, we studied the role of occupational health and
safety management system that is applied in the company that is
being studied for reducing the expenses to improve the performance
of the company totally. That we did a field study i
n the general
company for the manufacture of wool and carpets in Hama, through
questionnaire a random sample of workers and take into
consideration the characteristics of workers.
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.
