تأثير اختلاف بعض متغيرات التركيب البنائي "نوعية و كثافة خيوط اللحمة" و وصلات الحياكة على جودة الأداء الوظيفي لأقمشة مفروشات التنجيد

Abstract EN

In addition to the lack of research on the effect of structural factors and the different seams process on the functional performance of the upholstery fabrics, this study was conducted to identify the effect of some structural factors for these fabrics.

Synthetic yarns such as (polyester texture, polyester flat, polypropylene) used as wefts, densities of these wefts (15-20-25) per cm, and some types of seams during fabric production (simple seam - compound seam - French seam), For the purpose of producing furniture fabrics with more characteristics suitable for the functional performance produced for it (upholstery fabrics) using some structural structure variables (different yarns of different density) and different seams, with consistency of fabric and texture composition used, showing the importance of research in determining the most important factors affecting Producing distinct types of upholstery fabrics suitable for efficient use as upholstery fabrics, and their reflection on their functional performance.

The applied statistics were used to compare the above variables, and the statistical radar was used to select the best research samples produced after the mechanical tests on the finished products.

There was a clear variation in the test results of the samples under study (tensile strength, friction resistance and tear resistance), which showed a direct effect of the materials and the density of the wefts and the quality of the sewing seams on the different characteristics of the functional performance of the fabrics produced, Of the final product

1- Polypropylene yarns achieved the highest values for tensile strength and tear resistance, while texture polyester achieved the lowest values for these properties in the produced fabrics.

2- Polypropylene and flat polyester yarns achieved the highest values for friction resistance, while texture polyester yarn achieved a lower value for friction properties.

3- (25)weftcm achieved the highest values of the properties of tensile strength and resistance to tear, while (15)weftcm the lowest values of these properties, in the fabrics produced.

4- Polypropylene yarns achieved the highest values for the strength of the sewing strength, while the polyester yarn was the least value for the strength of the sewing strength.

5- The composite (English) seam achieved the highest values of the sewing tensile strength, while the basic seam achieved the lowest values of the strength, and achieved the French seam intermediate values between the two mentioned above.

6- The highest sewing strength for the best research samples were all for the English composite seam.
