Overview of Flow through Textile and Fabrics
نویسندگان
چکیده
An overview of single and multiphase flows through woven and nonwoven fibrous materials is presented. A computational model for analyzing fluid flow through such media is described and sample computational results are presented. It is shown that by generating virtual geometries that resemble the microstructure of a fibrous material one can study the fluid and particle transport through such porous media and compute their permeability and particle capture efficiency. As an example, the modeling strategy developed for evaluating the pressure drop and nano-particle collection efficiency of light-weight nonwoven air filter medium is described in details. Comparison of the results of the micro-scale modeling with the existing analytical models as well as the experimental data in the literature is also presented. Earlier studies on modeling permeability of multiand mono-filament woven fabrics are also reviewed.

A Bibliography of Iranian Textile and Fabrics A Review of Persian Books Related To Fabrics and Textiles
Studies in the field of textiles, fabrics and clothing designs so far have been more focused on three aspects of religious, historical or pragmatic approaches. Many books and magazines are dedicated exclusively to the presentation of models and patterns, but some also look at the techniques and methods of dress design with a specialist eye. It seems that the number of books related to clothing ...
متن کاملModeling Blood Flow Through Vascular Grafts
Vascular grafts based on permeable textile structures are now a widely accepted technology. The performance of the graft is largely dependent on the ability to allow controlled blood to flow through its thickness, yet predicting this flow rate is still not widely understood. An analytical model is in development based on fabric construction parameters, with the aim being to predict the permeabi...
متن کاملOn the use of image processing techniques for the estimation of the porosity of textile fabrics
This paper presents a novel approach to assessing textile porosity by the application of the image analysis techniques. The images of different types of sample fabrics, taken through a microscope when the fabric is placed over a constant light source, transfer the problem into the image analysis domain. Indeed, porosity can thus be expressed in terms of a brightness percentage index calculated ...
متن کاملAnalysis of the Restrictive Elements of China's Textile Industry in Upgrading Based on “Value Chain”
Our country’s textile industry is in the producing and processing field in the global value chain, so textiles’ added value is low and profit margins is narrow. Developed countries take up fields of high-grade fabrics production and advanced textile machinery manufacture. Because textile fabrics, textile machinery and equipment of China's textile industry fall behind developed countries, produc...
