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..

Tensile and Knot Performance of Polyester Braided Sutures

The success of a suture is generally linked to its mechanical performance such as tensile strength and knot slippage. The measurement of the tensile properties of sutures suffers from the absence of an international standard test method. In this paper, we present an experimental procedure for the measurement of mechanical parameters and k..

Thermal Comfort Properties of Wearing Caps from Various Textiles

The purpose of this research was to explore the effects of textile properties on the microclimate inside caps and on subjective wearing sensations. Physical tests on heat and moisture transfer properties of cap fabrics were conducted, as well as tests on the sensations from subjects wearing the caps. The temperature and humidity inside ca..

Elucidating the Design and Impact Properties of Composite Nonwoven Fabrics with Various Filaments in Bulletproof Vest Cushion Layer

Nonwoven materials have been used in ballistic protection applications because they offer the advantages of light and flexible fabrics. This study examined the ballistic protection efficacy of a nonwoven structure with high tenacity polyamide staple fiber as its main component. The nonwoven structure was reinforced with low-melt polyester..
