37、f Damask fabrics according to market needs . by GROSSE (CAD / CAM) System German company ,It was conducted the tests of the physical and mechanical characteristics of Damask (1181 ) product , and Damask (2) by modern laboratory devices.Table (7) shows the results of a study of the physical & mechani

38、cal properties of the modern Damask fabrics.,24,Table 7 physical and mechanical properties of the new improved Damask fabrics:,25,5-8 Discussion the results of tests,The Results of tests of tension resistance in direction of warp and weft for the variety Damask (1181) and Damask (2),were documented

39、and analysed .We have established detailed reports of the analysis and testing results of physical and mechanical properties of Damask in the Department of jacquard fabric , and executive instructions relating to its production, and tension strength and elongation diagrams for produced fabrics, were

40、 identified as the values of the terms of the specifications. Observation: we prepared an attachment contains resistance to tension diagrams in direction of weft & warp for all samples,26,5-8 Discussion the results of tests,1 - The test results of the physical and mechanical characteristics of A Dam

41、ask Fabrics , tables (from 4 to 7), and the results of tests of resistance to tension in direction of weft & warp of all fabrics produced meet the quality requirements of both functional and aesthetic, to increase the demand for modern products in market, absence of complaints by customers.2 -The ph

42、ysical & mechanical properties of yarns affect on Damask fabrics , table (3) show disparity between values of the assumed specification and real values, which affect the physical and mechanical properties, it is necessary to provide good yarns for industry .3 - Appears from the table 7 the high valu

43、e of the resistance to tension in direction of warp of the new varieties and increase the weight per square meter of the Damask (1181) and Damask (2) compared with the value of the resistance to tension in direction of warp of the items (705 - 710) in the tables (4-6), due to the use of thick weft y

44、arn in 1181 and a synthetic yarn in the Damask (2) which gives good features .,27,6 - Suggestions and Conclusions,1 - It has been defined and determined the characterization and classification of Damask fabrics and the physical mechanical specification , and it indicate the need to update the design

45、 of Damask to meet the requirements of the tourist industry, which is reflected in the national income , and economic and social development.2 - The study showed that Damask fabrics still enjoys a worldwide reputation for well-built through a long history back for several centuries is still required

46、 in the international market and reflects the Syrian heritage and the nobility of the textile Syrian industry where history come from deep road , for this reason it is recommended the revival of the industry and maintain.,28,6 - Suggestions and Conclusions,3 -The production of new Damask fabrics wit

47、h new drawings and specifications fulfils the requirements of fashion leads to quality & productivity improvement, and increase the products added value, as the selling price of new products increases to 60% . 4 - The development of scientific methodology to study, analyze and diagnose the problems

48、of the textile industry, through the research model, which benefit from it the textile companies and the scientific institutes.,29,6 - Suggestions and Conclusions,5 - The information contained in the research contribute to identify the problems of the state and society and to find solutions and incr

49、ease the stock of knowledge and keep pace with market requirements and develop product lines.6 - The results, reports, laboratory analysis diagrams , which has been documented and saved, constitutes a scientific base for developing the Syrian Standard, which improve the prestige of Damask fabrics in
