Ask ChatGPT about the research

research The aim of this is to find an explicit relationship between the strength of fibers, bundle and yarns. The CV values of the strength are given as well. This provides a relatively simple method for estimation of staple yarn strength, while avoiding some difficulties of an empirical method. The effects of important factors such as fiber length and thickness, twist and count of yarn are considered. The results are verified by published data in Mechanical Engineering of Textile Industries and Their Technologies, Faculty of Mechanical and Electrical Engineering, Damascus University. and also in Al-Kumasiah company in Damascus city. This research provides suggestions if we apply it it will help in estimating directly the yarn strength without manufacturing and suitable testing of the yarn.

In the past four decades, the woven fabrics has been subject to inordinate competition which has primarily come from the fashion (short runs), knitting, and nonwoven segments. The weaving machinery manufacturers answered the pressure of competitio n by concentrating on the design of looms that offered relatively very high speeds. Obviously, to meet the demands of the higher productivity on the loom, the material characteristics and the quality and efficiency of the preceding processes also needed to be improved. And this improvement is doing by encapsulate the yarn with size film before weaving, by the sizing process which considered as the heart of weaving. this research is aimed to studying the affective factors of sizing, and define the ideal values of it. This research reffered to the effect of sizing machine speed on yarn size witting time and then on its coating percent, other side the rollers squeezing pressure of sizing machine and sizing solution viscosity affect on yarn size coating percent too which affecting on its resistance toward weaving operation and usage later, because , the success of sizing process leads to success the following stages like, weaving, finishing, and then, success in fabric usage.
The aim of this study is to determine strength of adhesive single-lap joints of Aluminum alloys which are widely used in geometric applications. It was investigated to define the influence of overlap length and surface roughness value on shear stre ngth of achieved adhesive joints. It was used Epoxy and Acrylic adhesives to prepare adhesive joints and all the specimens were subjected to axial tensile tests and the results are presented as a comparison. Results of those tests showed that shear strength increased with increasing each of overlap length and surface roughness of adherends and Acrelicadhesiveproduced4better results according to failure mode of tested samples.
Ring, Rotor(O.E) and Air vortex spinning systems provide yarns with different structures and properties. Each system has its limitations and advantages in terms of technical feasibility and economic viabilit y Ne 30, 100%cotton yarns were produced from the above systems and knitted in single jersey machine .The Rotor Spun yarns found with frequent breakage during knitting.
Yarn quality produced is essential to the economic success of spinning plants. International competition and market requirements dictate the necessity to produce quality yarns at an acceptable price.
The purpose of this study was to evaluate the shear and tensile bond strengths of orthodontic brackets bonded with self etching primer and resin-reinforced glass ionomer cement in comparison with light cured resin adhesive. The tested self-etching primer and adhesive systems produced bond strength values higher than that of the light cured resin adhesive whereas the resin-reinforced glass ionomer cement showed a significantly reduced bond strength . Clinically, the use of self-etching primer and adhesive systems is suitable for orthodontic bracket bonding.
