Evaluation of Package Density Method for Measuring Bulk of Air-Jet Textured Yarns
Bulk is the most important characteristic of air-jet textured yarns. It plays a decisive role in determining the thermal and mechanical behaviour of fabrics made from these yarns and fabric comfort. Measurement of textured yarn bulk is ther...
Determining Diameter of a Yarn with Unknown Count
This research work presents a perfect method to determine yarn diameter based on scientific understanding of things nature and avoiding the obstacles of classical methods of yarn diameter measuring by magnification or calculating it from em...
Quallity and Spinnability Assessment of Egyption Cotton
The textile industry in Egypt depends mainly on cotton and cotton represents 90% at least of its consumption from fibres. It is well known that the Egyptian cotton has unique properties and is of highquality and spinnability in comparison t...
Effect of Twist Factor and Filament Tension on Properties of Egyptian Core Spun Yarns
Filament tension and twist factor are important parameters that control filament central position and, consequently, properties of core spun yarns. What is the expected interaction between them is a question that is answered in this article...
A New Design for Compact Yarn Production on Ring Spinning Machine
MOST OF THE YARNS AVALIABLE ON MARKET ARE PRODUCED ON THE RING SPINNING MACHINES COMPARED TO THE OTHER SYSTEMS SUCH AS THE OPEN END, REPCO, PAROFIL, ETC. THIS DOMINATION IS DUE TO THE FLEXIBILITY AS WELL AS QUALITY OF THE YARN PRODUCED WHIC...
Yarn Run-In as an important parameter in warp knitting
Yarn length consumption represents one of the most important parameters of warp knitted structures, used for the machine adjustments and for some important fabric properties. The paper presents teoretical and experimental research upon the...
An Investigation of the Hairness of Core-Spun Yarns Containing Spandex (Lycra )
Hairiness is one of the important yarn characteristics, which affects weaving, knitting, preparation, dyeing and finishing process in textiles. As a result of increasing consumer expectations from textile products during the last decade, ya...
