The last years of the 20th century have seen real changes and rapid developments in all areas of life, and modern techniques in the field of textile printing have emerged, occupying the first positions in strategic fields. Therefore, this research aims to study the effect of using different concentrations of ammonium sulfate and citric acid in the print paste on the burn-out rate produced on Cotton/polyester blended fabrics in terms of weight loss, tensile strength and elongation to reach the best concentrations that can be used during the burn-out printing process and using it to print ladies' clothing fabrics as one of the most important areas for textile printing designers, as burning printing offers the clothes a unique value that helped to change the course of fashion through the presentation of texture, shape, and appropriateness that The designers dreamed of it. Fabrics used is cotton 100%, polyester 100%, cotton/polyester 35/65, cotton/polyester 50/50, printed in silk screen Research problem: The search problem can be identified in the following question: What are the effect changes resulting from the use of different concentrations of ammonium sulphate and citric acid in the burn-out printing paste and how are they used to produce different texture effects for the production of ladies printed fabrics? Objectives: Study the effect of different concentrations of ammonium sulfate and citric acid in the printing paste on the weight loss ratio of cotton/polyester fabrics and Study the effect of different concentrations of ammonium sulfate and citric acid in the printing paste on the tensile strength and elongation of cotton/polyester fabrics.Significance: Identify the method of burn-out printing as one of the modern methods of printing textiles. Identify the best concentrations that can be used to effect burn-out printing on cotton/poly-esters fabrics. Take advantage of the effect of burning printing in enriching the design of ladies printing fabrics with modern technological thinking and design construction that goes hand in hand with the latest international fashion lines to meet the demands of the consumer. Methodology: The research follows the analytical and experimental descriptive approach by: Analytical descriptive approach: study the effect of the concentrations of ammonium sulphate and citric acid in the burning paste on the characteristics and properties of the printed fabrics. Experimental approach: on the practical side of the experiment using different concentrations of ammonium sulphate and citric acid in the burning paste and use it to print women's fabrics. Results: it was found that: There is a direct correlation between the increase in the rate of burn-out Chemicals in the print paste and the resulting burn-out rate (weight loss). There is a direct correlation between the proportion of cotton in the material to be printed and the resulting burn-out rate. There is an inverse relationship between the concentration of the burn-out Chemicals ratio in the printing paste and the degree of tensile strength and longing of the material. The burn rate resulting from the use of ammonium sulfate is better than the burn rate produced by citric acid. The best concentration for ammonium sulfate is 35g/kg. The best concentration of citric acid is 30g/kg |
