Cometabolic Decolorization of the Reactive Azo Dye Orange II by Geobacillus stearothermophilus UCP 986

The decolorization of solutions containing the textile reactive dye Orange II by the bacteria Geobacillus stearothermophilus (UCP 986) was investigated. The experiments were statistically evaluated by two-level-four factor (2 4) full factorial design, as aeration, azo dye concentration, inoculum size, and culture media. The best results w..

Study on the Principle of Yarn Formation of Murata Vortex Spinning Using Numerical Simulation

In Murata vortex spinning (MVS), the principle of yarn formation is closely related to the flow field inside the nozzle. This paper presents a numerical simulation of the flow characteristics inside the nozzle of the MVS machine. A three-dimensional grid and the realizable k-ε turbulence model are used in this simulation. The numerical re..

Automatic Identification of Ramie and Cotton Fibers Using Characteristics in Longitudinal View, Part I: Locating Capture of Fiber Images

This paper introduces a new fiber imaging system that can automatically capture a series of microscopic fiber images in the longitudinal view to form a panoramic image of long-fiber segments for reliable identifications of blended fibers. The panoramic image shows thumbnails of long fibers without missing or duplicating any segments on th..

A Genetic Algorithm-based Solution Search to Fuzzy Logical Inference for Breakdown Causes in Fabric Inspection

This study presents an intelligent diagnosis system consisting of a screening mechanism, which can effectively narrow down the search range for possible breakdown causes, and a search mechanism (based on genetic algorithm), which can help find the solution (i.e., upper boundaries and lower ones) to the inverse fuzzy equation. Through thei..

Predicting the Seam Strength of Notched Webbings for Parachute Assemblies Using the Taguchi's Design of Experiment and Artificial Neural Networks

Webbings are used in parachute assemblies as reinforcing units for the strength they provide. The strength of these seams is an important characteristic which has a substantial influence on the mechanical property of the parachute assemblies. It is well established that factors such as fabric width, folding length of joint, seam design an..

An Approach Aimed at Fabric Consumption in Shirt Production

Today, clothing factories have to strictly control their costs to survive and continue their success. Fabric cost constitutes about half of a garment cost. For this reason, it is important to calculate the fabric cost of a garment precisely. The study described in this paper aims to develop software that will calculate the fabric consumpt..

Anti-mite Covers: Potential Criteria for Materials Used Against Dust Mites

There are many types of material used to construct bedding encasing for dust mite and allergen protection, but relatively few have been evaluated for their anti-mite properties. This study surveyed the anti-mite/allergen properties and physical characteristics of covers with a view towards establishing potential parameters for evaluating ..

Effect of Manufacturing Parameters of Covered Yarns on the Geometry of Covering Components

This study deals with numerical simulation of structure of covered yarns produced on a double covering machine. Four manufacturing parameters of covered yarns such as delivery speed of covered yarn, rotational speed of two hollow spindles, and core stretch ratio during wrapping were used to simulate coil length indices of both covering co..

Extrusion of Polyethylene Through a Square Slot in Rotating Die Systems

In a melt extrusion process consisting of a static die (spinneret), the geometry of extrudate is mainly dependent upon die slot geometry, rheological properties of polymer, pressure drop and drawing conditions. However, in a patented Netlon® process, a static die is replaced by two counter-rotating dies in a melt extrusion process for pro..

Analysis of Polymeric Braided Tubular Structures Intended for Medical Applications

In this study, monofilament tubular braided structures were fabricated and their performances were analyzed. The braided tubes are in three-dimensional form, made of polyester monofilaments intended for use in medical applications. This type of structure, called a stent, is used to open clogged arteries and veins by exerting radial forces..
