Assessing Fabrics Wrinkling by Image Analysis

In this paper, the features of fabric wrinkle structure are analyzed, by image processing technique. The wrinkle images are processed and character parameters are extracted. The wrinkle side surface area ratio of image gray level intensity, the standard deviation of total pixels' gray level intensity and the standard deviation of wrinkle block area are adopted to evaluate fabric wrinkling. The results show that these three character parameters can be served for ranking the wrinkling. It provides a feasible objective method for fabrics wrinkling degree assessing.     

Research on Radiant Carrier of Matching Radiant Type Far Infrared Textiles

This paper deals with the radiation effects of different kinds ofradiant carriers used in making far infrared textile materials.From two radiation experiments,methods of testing radiation ef-fects of carriers have been found,results of the experiments arediscussed.Finally,some conclusions for choosing appropriateradiant carrier are drawn.     

Study on Surface Optimization by Ion Beams

Preliminary tribo-mechanical properties of IBED filmsof GCr15 bearing steels have been studied in this paperalong with the comparison between IBED films and PVDfilms as well as non-implanted surface in wear resis-tance,micro-hardness,friction and surface morpholo-gy.Experiments gave a consistent picture and statedclearly that TIN films can really improve the tribo-me-chanical properties of materials and have practical usesin a certain sense.However,further theoretical and ex-perimental studies must be performed in respect thatthere are some defects on IBED films.
