Abstract
The price of fabrics has reduced to a high percentage due to the presence of defects. The quality of fabrics is determined by the defects present in it. The fabric defects include variation in color or width inconsistencies, hairiness, slubs, broken ends, etc. Yarn density measurement is an important factor for fabric quality and difference in yarn density in same cloth is considered as major fabric defect that should be rectified without fail. This process of yarn density measurement take place after production process and rectification if any is done in the appropriate weaving stage. The thread density of woven fabric is currently measured with manual operations. One of the methods is to count the number of warp and weft yarns in a unit length is with a textile analysis magnifying glass. The manual methods are not only time consuming but also require more attention and concentration from an expert analyst. The error percentage of such detection is more. Also, the thread density detection results are influenced by the physical and mental conditions of the operators. Thus, it is highly desirable to develop an automatic measuring system for the thread density of woven fabric.
