Liquid Flow Behavior in Washing Process of Textile Fabrics. I.

Overview of Flow through Textile and Fabrics

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 por...

Machine Vision Based Inspection of Textile Fabrics

Several issues on automatic inspection of textile fabrics are discussed in this paper. To avoid the intense computation for real time inspection, we suggest a parallel pyramid hardware architecture consisting of several channels with CCD cameras in different resolutions working simultaneously. In inspection algorithms, we use a hierarchy of improved BP neural networks which demonstrate a tree s...

FLOW BEHAVIOR OF MOLTEN METAL IN ALUMINUM LFC PROCESS

The effects of gating system and pattern geometry on the metal flow in the lost foam casting (LFC) process have been investigated using glass covered mold and video recording system. Unlike convectional casting process, the type of the gating system showed little effect on fillability in lost foam, but pattern thickness had large effect on mold filling. The mold filling behavior seems to be con...

Detecting Defects in Textile Fabrics with Optimal Gabor Filters

detection scheme for solving the problem of automated defect detection for textile fabrics. In the development of the scheme, Gabor wavelet network (GWN) is deployed as the major technique to extract texture features from textile fabrics. An optimal Gabor filter is then designed on the basis of the features extracted. The proposed defect detection scheme consists of one real-valued optimal Gabo...
