The ring spinning is the end of the stages of the cotton yarn spinning by traditional methods Before Yarn winding Process, and is characterized by being one of the best methods used to produce thin yarns with high durability of short fibers, it can also produce cotton yarns from No. 4 to No. 240 E, and due to the multiplicity Types of cotton material, and multiple sources, the research was conducted to unclear the impact of the use of different types of cotton on the quality of yarns produced by The ring spinning of yarn, and this study was conducted with the aim of the possibility of producing cotton yarns with different materials and types with different number ring spinning system with better properties in functional performance In the production of (12) samples of cotton yarn with (4) different cotton materials (Giza 86, Giza 90, Greek cotton, Burkina cotton),and (3) cotton yarns of different number (16/1, 20/1, 24/1), and conducted various tests (RKM, elongation, Naps, thick places, thin places and the percentage of irregularities on the yarns to illustrate the effect of using different types of cotton material on the yarns produced in the study, and the results after statistical analysis showed a clear difference in many tests, which shows the obvious effect of the research variables on the produced yarns, and the importance of research in determining the best Types of cotton material used in the production Yarns of different numbers, which are produced by ring spinning system, reflected on job performance, and the results were within RKM values for Giza 86 cotton reached the highest, while it came for the lowest Burkina cotton material, The elongation values for the highest Greek cotton, while the elongation values For the lower Burkina cotton material, The values of Naps of the highest Burkina cotton material, while the value of the cotton material came Giza 86 least, Values came in the thickest places of the highest Burkina cotton material, while the values of the cotton material Giza 90 were lowest , The values of the thin places of the highest Greek cotton material, while the value of the thin places of the lowest the cotton came to Giza 86, and Giza 90, , The percentage of irregularity of the highest Burkina cotton material was achieved, while the cotton material came to Giza 86 the least.

Open end spinning is one of the final spinning techniques used in the production of cotton yarn, and is characterized by increased production and reduced economic cost, and due to the low spread of open-end yarn technology, and limited production despite the low cost and the impact of its use in the production of cotton yarn of different types on the characteristics and performance This study was conducted in order to study the production of different cotton yarns with the system of open-end yarn with better properties in functional performance and economic cost, by producing (12) samples of cotton yarn of different number and composition, with open-end spinning, producing (6) samples of cotton yarn for the same number, with ring spinning, with different yarn number 30/1, 16/1, 20/1, 24/1, 6.5 / 1, 4/1, and conducted Different tests on yarns to illustrate the effect of using the open-end yarn in the production of the yarn under study compared to the technique of ring spinning yarn in their production, the results showed a clear difference in some yarn tests such as tensile strength and coefficient of variation Research in identifying the best types of yarns produced by the system of open-end yarn, reflected on Their performance, after analyzing the results of tests statistically, It is among the results Tensile strength values and RKM values for raw materials 50% cotton : 50% exhausts exhaust higher than the cotton exhaust. (Exhaust cotton and mix cotton with exhaust),Values of naps, thick places, and the thin places of the material 50% cotton : 50% exhausts less than exhausts cotton for all samples of the open end, The irregularity of the material was 50% cotton + 50% exhaust less than the raw material exhaust cotton for all open end samples. The quality coefficients of all the research samples showed that the sample number 12 produced by the open-end system of the material 50% cotton + 50% exhaust and the yarn number 4/1 with a quality factor (94.67%) followed by the second sample number 10 produced by the open-end system of the material 50% Cotton + 50% exhaust and yarn number 6.5 / 1 with a quality coefficient (93.68%), and in the third place came the sample number 18 produced by the ring-spinning system of the material No. 13 Produced by ring spinning system of material cotton and yarn number 30/1 quality factor (31.23%).

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 product1- 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.
