يرتكز البحث على استخدام أنواع مختلفة من المرسخات المعدنية، عبارة عن أملاح المعادن، في عملية الصباغة باستخدام المستخلص المائي لأوراق الكينا. المرسخات المستخدمة هي كبريتات الألمنيوم و البوتاسيوم المائية، كبريتات النحاس المائية، كبريتات الحديد المائية و خلائط من هذه المرسخات. دراسة تأثير هذه المرسخات على العملية الصباغية.
This research is based on the use of different types of mineral mordants, mineral salts, in the dyeing process using the aqueous extract of eucalyptus leaves. The used mordants are aluminum potassium sulphate, copper sulphate, iron sulphate and mixtures of these mordants. Study the effect of these mordants on the dyeing process.

In this study we used ultrasonic technology as a means of
enhancing dyeing process efficiency of polyester fibers with
disperse dyes, which had frequency 42kHz and, we studied the
behavior of dye when the polyester dyed with (US) and with
traditional dyeing methods (without US).
This study aims to shed light upon bleaching process, study the
influence of each substance during the process and the best time for
bleaching in addition to clear up the effect of water.
In this study , a dyeing process of vat dyes was carried out for
cotton fabrics (100%) at an optimal conditions for material's
concentrations (sodium hydrosolphite , oxidization agent
,alkaline agent) to obtained a reference sample using for
comp
arison with another samples which dyeing at difference
concentrations of materials and different oxidization agent and
conditions of works ( work at close condition or open) , and it
was observed the decrease of fastness's values for the tester
samples against dry and wet rubbing opposite of reference
sample and that due to the difference of concentration of
reducing agent and the weakness of bonds between the dye
and textile because of the difference of oxidization conditions.
Textile industries are very important in Syria. Sham Countries are known with it, and the most famous
kinds of it are: Damsko and Brokar, that spread in the world. This industry is a result of many industries
starting, from spinning then fabric and
dyeing and sewing for the final product. Dyeing is an important
phase in this industry, because it offers to the product its beauty and specialty that comes with many
gestations and the changes of fashion and style, and it's an artistic and scientific industry that needs high
skills and numerous staff for work and operating.
The purpose of this research is to study noise caused by machines in three companies working in dyeing
and preparing clothes, by measuring noise levels with anchor equipment and comparing the results to
international standards in order to estimate the amount of dosages that workers in industrial
establishments face, and to come up with recommendation to reduce noise levels.
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.
