Abstract: The present study was carried out in Cotton Technology Res. Department Cotton Res. Institute, Agric. Res. Center at Giza in 2018 season. Aiming to Investigation the relationship between fibre microscopic properties and fibre mechanical properties. Lint cotton samples of four micronaire levels (Mic levels) from two Egyptian cotton genotypes; namely; Giza 94 and Giza 95 representing Delta and Upper Egypt LS genotypes were tested by HVI and Image analysis methods. The results indicated that over maturity level shown the highest values of each Perimeter (P), area of cross section (ACW), area of secondary wall (ASCW) degree of thickening (Ɵ), Maturity ratio,.....

Title	:	A study the effect of modifications in compact spinning machine on the yarn quality properties
Country	:	Egypt
Authors	:	Eman Y. Abd-Elkawe
	:	10.9790/019X-12030716

Abstract: Rieter’s company had added some modifications (The Q-Package)to compact spinning machine K44 in order to increase the machine efficiency and obtain the best yarn quality properties. Q-Package was presented for the first time at the ITMA 2015 in Milan. The Q-Package is the combination of new developments in the drafting system of K44 compact spinning machine. The new K 45 is modular in design, and the total machine concept offers maximum reliability and flexibility with up to 1632 spindles.The mill-proven Ri-Q-Draft drafting system with pneumatically loaded guide....

Abstract: An experimental Study was conducted in spinning mills ,using two new Egyptian cotton genotypes belong to Upper Egypt LS category and three imported upland cotton genotypes i.e., (American, Greek, and Sudanese) aiming to evaluate the fiber and yarn properties of Upper Egypt cottons in comparison to the imported Upland cottons used in the domestic textile mills. All the cotton genotypes were spun to 30s Ne carded and combed ring spun yarn count at "4.0 twist multiplier, except the Sudanese cotton which could not be spun to combed yarns because of its inferior....

Abstract: This research carried out the design, construction and performance analysis of locally made portable wind turbine for domestic applications. Today, world is immensely seeking clean, renewable and cost effective energy to reduce greenhouse gases, which problem is becoming a global issue. Constructing a small wind turbine provides useful quantity of environmental friendly energy, to supply houses and workshops, without ejection of carbon-monoxide into the atmosphere. The conversion of kinetic energy in form of mechanical energy is transformed to generate electrical energy by vertical axis wind turbine, derived from 12 Volts car alternator. The car alternator.....

Abstract: By measuring the dependence of conductivity on temperature and analyzing this dependence within the framework of the reduced conductivity activation energy, it was found that in composite polymer materials containing Nickel nanoparticles in the region below the classical percolation threshold in the studied temperature range, there are three regions with different temperature dependence. The origin of these dependencies is discussed in terms of a spatial-structural hierarchical model.......
