Today, most researches are directed to urge the use of clean technology to reduce environmental pollution with industrial and chemicals dyes, and in the field of minimization from pigment contamination, many researches tend to use natural dyes to resist ultraviolet rays and the growth of bacteria and environmentally friendly as an alternative to synthetic dyes, as a large part of industrial dyes is lost during the manufacturing stages, which means that many everyday tons of industrial dyes find their way into the surrounding environment causing pollution.

Research problem:  The research problem is summarized in the following questions: *What is the possibility of extracting the color of the Moroccan Clementina peel? *What is the possibility of using the Moroccan Clementina peel tincture to treat cotton fabrics? *What is the possibility of improving some of the properties of the used cotton fabrics in terms of (resistance to bacterial growth, Ultraviolet permeability, air permeability, water orption, tensile strength, elongation and depth of color) in the form of Moroccan Clementina peel? *What is the possibility of using dyed cotton fabrics in the form of Moroccan Clementina peel in women's clothes? Research objectives: *Environmental protection of pollution, using environmentally friendly natural dyes.

*Determining the best conditions for the treatment of cotton fabrics in the form of Moroccan Clementina peel to obtain the highest standards of dyed fabric.

*Taking the advantage of the treated fabrics with the dye of Moroccan Clementina in women's clothes.

Research methodology: The current research follows the analytical and experimental approaches by applying the practical experiment to validate the assumptions and analyze the relationships between the variables and clarifying them to achieve the goals of the research.

The research found: *There is a statistically significant difference at the level of (0.05) between the type of thread material (tensel, bamboo, fabran) in the acquisition of used cotton fabrics in women's clothing resisting Ultraviolet radiation and bacterial growth using Moroccan Clementina peel tint: Ultraviolet protection factor (UPF), tensile strength (kg), Elongation ratio (% ), air permeability (cm³ / cm².

th), orption time (th), color depth, resistance to bacterial growth (E.

coli, Staphylococcus aureus).

*There is a statistically significant difference at the level (0.05) between the time of pigment extraction (6, 4, 2) in the acquisition of used cotton fabrics in women's clothing resisting Ultraviolet radiation and bacterial growth using the Moroccan Clementina peel tincture: UV protection factor (UPF), tensile strength (kg), Elongation ratio (% ), air permeability (cm³ / cm².

th), orption time (th), color depth, resistance to bacterial growth (E.
