A New Method of Measuring Yarns Twist
Described is a new method of yarn-twist measurement based on observation of the behaviour of yarns during measurement of their twist. The method consists in a two-way twisting, i.e. untwisting and re-twisting, of the test sample pre-loaded...
New Spinning Technologies: How They Impact the Quality Requirements of Long-Staple Cotton Fibers
In today-s technology, new spinning techniques have been introduced to meet increasing quality and production demands. This paper deals with various constraints on fiber quality imposed by new technologies. Specifically, it deals with fiber...
Hand Related Mechanical Behavior of Enzyme Treated Yarns Representing Different Spinning Systems
This work evaluated the change in the low-stress mechanical behavior of 100% cotton and cotton/polyester yarns after the yarns were treated with a cellulase enzyme. The yarns made on four different spinning systems using the same fiber stoc...
An Expert System for Faults Pattern Classification in the Spinning Mill
This work is concerned with the design and implementation of an automatic system for detection and classification of yarn faults. Opto -electronic data processing makes it possible to detect and classify faults and identify their source. Th...
Comparison of Conventional Ring and Compact Yarn Properties with Special Reference to Cotton/Acrylic Blends
.In this paper, properties of 50/50 cotton/acrylic blend yarn produced on compact and conventional ring spinning frames were compared. Various acrylic fibres namely relaxed, unrelaxed and microfibres were used in the blends and three differ...
A Simple Model of the Worsted Drawing System and its Application to Yarn Quality
A simple model of the worsted drawing and spinning sequence has been developed, which takes account of the various components of irregularity at every stage of processing. The model can be used to determine how well each processing step is...
Indirect determination of yarn thickness
The hairiness and the peculiar shape of the ring-spun yarns cross-section prevent the direct determination of yarn thickness as well the yarn diameter. A recently developed method aims at the indirect measurement of yarn thickness using a s...
Effect Of Modification and Processing Variables on Yarn Formation and Yarn Characteristics in Mono-Cylinder Friction Spinning
In recent years, one of the advanced spinning systems became an important fact of textile industry, that is the friction spinning system. One of its inherent capabilities is producing unconventional yarns with higher speeds. The friction sp...
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...
