Improving the Performance Efficiency of Cotton Youth Clothing (Poplin Fabric) in the Kingdom of Saudi Arabia Printed using Natural Dyes that are Environmentally Friendly The general trend has now become towards the production of environmentally friendly materials as a result of the increase in sources of pollution around us in all fields and in the field of textiles and textiles, we find that woven products at all stages of production, but in the stages of its cultivation, many toxic and harmful chemicals are added to it, which give it some of the required properties, but at the same time cause health damage to the skin Survey studies have shown that human exposure to industrial dyes used in clothing is one of the important risks of cancer, allergies and pushing This is due to the recent trend of research to the use of natural dyes to reduce environmental pollution and preserve human life, and one of its most prominent advantages is that it is environmentally friendly due to its ability to decompose into its natural components and reduce the toxic substances resulting from it as well as not cause allergies. The aim of the current research was to study how to extract some natural dyes from plant sources available in the environment and safe used in dyeing cotton fabrics and dyeing young people's clothes in the Kingdom of Saudi Arabia with decorations and inscriptions with dye to improve the performance efficiency of young people's cotton clothes and to identify the quality of dyes in dyeing cotton fabrics and these dyes were (hibiscus - turmeric - safflower - henna - beets - cabbageRed – Sidr – sumac seeds – pomegranate peel – red sweet pepper – green tea), has been dyeing cotton fabrics 100, where the samples produced (12 samples per test), of cotton fabrics, as well as the study was interested in conducting laboratory tests to find out the change in the properties of fabrics of young clothes resulting from the treatment to lead dyeing fabrics with natural dyes intended for the highest efficiency and quality and it is clear from laboratory analysis that Dyeing the fabrics of the clothes under study with natural plant dyes improves their functional and color properties, represented in (inhibition of the growth of positive and negative bacteria of the gram dye - color fastness to friction - color intensity - color fastness to light - color fastness to washing - color fastness to sweat), and the results were as follows There is a statistically significant relationship at the level of (0.05) between the use of natural dyes and improving the efficiency of the performance of dyed youth clothes. One of the most important recommendations is to pay attention to natural plant dyes and employ them in research in the field of plastic art and the field of textile printing to reduce environmental pollution.
