Provisional Patent Application Filed

In the textile industry, there are different types of machines that are able to assess the quality of fibers, with the most common being the high volume instrument (HVI). HVI systems take parallel bundles of fibers and report on the mean length and uniformity index of the bundle. However, there is very little data reported concerning individual fiber metrics of the distribution of fiber lengths. Without these added fiber qualities, the ability to accurately predict yarn quality becomes much harder.  One way around this lack of information is to use a different method of fiber analysis known as Advanced Fiber Information System (AFIS). AFIS is able to provide a more detailed report about individual fiber qualities; however, AFIS testing is costly, takes more time, and is not as widely distributed as HVI.  

Using the existing HVI system, this technology extracts the full fibrogram and its raw data then uses these parameters to determine yarn quality with much higher accuracy than current HVI outputs and AFIS testing.
