Research progress and existing problems about characterizing fuzzing and pilling

In view of the mechanism of fuzzing and pilling and associated problems,this paper reviewed the advances of characterization technology by combination of the available testing methods and characterization science. The commonly-used fabric pilling testers,such as Martindale abrasion tester, ICI pilling box and the random tumble pilling tester,and image processing and prediction by the artificial neural network were introduced,along with retrospect of previous research work done in the field. It is argued that the present research on the mechanism and characterization of pilling lays emphysis on the explaination of the cause of formation of pilling and the discussion on solution and characterization based on the mechanism,but neglects making profound investigation into the mechanism and characterization of fuzzing. The importatance of the research on fuzzing and pilling mechanism is emphasized,pointing out the drawbacks of various characterization technologies attributed to the insufficient research on pilling mechanism. It also reveals the importance of the characterization technology for clarification of fuzzing and pilling mechanism. This study will help essential representation of fuzzing and pilling mechanism.
