The development of cotton-yarn-quality predicting system

A new cotton-yarn-quality predicting system was developed by using the merging programming technique of VB and Matlab. Using this system, the tenacity and evenness CV% of the cotton-yarn processing by conventional spinning at standard temperature and humidity can be predicted through inputting some fiber properties into the system, such as the percentage of impurities, the principal length, the percentage of short fiber, the degree of maturity, fiber strength and the value of Micronaire. And also it was verified that the system did the good job for predicting yarn tenacity and evenness CV% exactly with the relative error of less than 4% after the model being trained. The accuracy can meet the demand of spinning factories and so the predicting results would be useful for guiding the spinning practice.
