Automatic identification for processing parameter of slub yarn

The purpose of this study is to improve the speed and precision of testing the processing parameters of slub yarn,and use of computer to carry out this testing is proposed.The basic principal of testing the processing parameter of slubby yarn was introduced.And we developed a slub yarn testing system which was used to test the sample of slub yarn.We got time sequence chart of thickness of slubby yarn,distance sequence chart of slub length and slub space,and distribution charts of slub length,slub space and slub scaling factor.The results tested showed in good agreement with the originally set parameters.The resulting errors were analyzed also.Experiments demonstrated that this testing system is effectively,and can be adopted in production.
