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 fiber properties and its high content of reducing sugar (sticky cotton). The results indicated that Upper Egypt LS......

|Title||:||An Investigation of Bursting Strength on Single Jersey Weft Knitted Fabrics|
Abstract: This paper investigates the bursting strength performance of single jersey weft knitted fabrics. The objective of the study is to find out the impact of the yarn count ,stitch length , stitch density, fabric thickness, loop shape factor, tightness factor ,GSM and porosity on the bursting strength of the single jersey weft knitted fabric. The experimental results have been statistically evaluated with Analysis ofVariance (ANOVA) test , Results show thatstitch length , stitch density, fabric thickness, loop shape factor, tightness factor ,GSM and porosity areeffective on bursting strength and individual ANOVA test results show that stitch density , fabric thickness , tightness factor , GSM and porosity are Individually effective on bursting strength .the GSM parameter of the fabric is fundamental for bursting strength , the correlation relation and R square values of GSM with bursting strength found to be in order 0.839& 0.9438..

Abstract: Ring frame is the last machine for producing yarn by spinning. For producing a better quality yarn, some of the factors are important. It also need to ensure the quality of yarn is same for all the position of ring frame. Sometimes it shows variation. In this study, we tried to find the problems for which the quality of yarns are varied & finally provided some solution how to minimize the variation. we observed the spinning position of Ring spinning machine such as Traveler, Apron, Drafting Arrangement, Lattice apron, Ring cup, Spacer etc. that can make deviation on the final yarn properties like C.S.P, T.P.I, I.P.I, CV%, Naps , hairiness, U%, Thick place, Thin place, Mic, +b (yellowness) and so on. From different points +b (yellowness) is one of the important factors. Here, we have to emphasized on +b (yellowness) value of fibre when bale mixing. If we can minimize the variation of +b (yellowness) value of yarn among the bales we can produce a less quality variation in the final yarn.8..

Abstract: The Thermal Analysis and Drying Time characterization of green adhesives using agro and plastic waste materials as composite for domestic and industrial utilizations was carried out. Preparation of adhesive filler (Rice Husk Ash) and formulation of adhesive binders (Polystyrene waste and Arabic gum) were conducted. A synthetic adhesive (Sample A) served as a control. Standard adhesive and samples formulated were labeled A, B, C, D, E, F and G respectively based on varied quantities of fillers and binders. Thermal analysis and drying time of the adhesives were investigated......

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.
