Abstract

The weaving process is constantly evolving in terms of productivity, quality, and possibilities of fabrication of different fabric structures and shapes. This article covers some issues that have still not been resolved and represents distracting factors in the woven fabrics production. In the development of woven fabric using the CAD technology, it is inevitably a deviation of the virtual image on the computer screen from the woven sample. According to comprehensive industry analyses, the findings of many authors who contributed to the resolution of these problems can be concluded that these problems are still present in the development and production of striped, checkered, and jacquard woven fabrics. In this article, jacquard, multicolor woven fabrics were investigated, with deviations in pattern sizes and shades of color in warp and weft systems compared to virtual simulation on the computer, as well as the tendency of the weft distortion arising from the weaving process leading to the pattern deformation.

Introduction Coronary artery disease (CAD), especially acute myocardial infarction, is becoming one of the major causes of morbidity and mortality worldwide [ 1 ]. Multiple factors, such as genetic variants, lifestyle and environmental factors, are believed to be involved in the occurrence and progression of CAD [ 2 , 3 , 4 ]. In recent years, more and more researchers carry out large scale genomewide association studies (GWAS) to elucidate the pathogenesis of CAD at the gene expression level and the results have demonstrated that gene polymorphisms are
