The study is concerned with the use of environmentally safe natural plant extracts and extraction of some natural extracts from vegetable sources available in the environment and safe used in the treatment of cotton and blended fabrics to improve the functional properties of these fabrics and the resistance to ultra violet radiation. The researcher treated three types of cotton clothes (Cotton 100% -50% Cotton: 50% Polyester - 35% Cotton: 65% Poly Ester), The study was conducted using (green tea extract - thyme extract - cumin extract and turmeric - ginger extract) in three different concentrations (10/20/30 ml / l) In addition, the study is concerned with conducting laboratory tests to detect changes in the properties of the clothing fabrics resulting from the treatment. The protective clothing is designed with the highest efficiency and quality. The laboratory analysis shows that the clothing fabrics studied with plant extracts improve some properties of the cloth such as air permeability, Water absorption - High U V protection rate - Rupture resistance - Pilling resistance) These properties are further enhanced by increasing concentration of plant extracts. One of the most important recommendations is to pay attention to the benefits of natural plant extracts and to try to employ them in other research and to work on the use of environmentally safe materials Various processing mechanisms to reduce environmental pollution.
