In everyday life, we often find clothes to wear for a long time, like the color fades. On the whole dress, some places still the same as before, and the color in some places has clearly not recognize. In fact, for the above problems, it is not difficult to explain, mainly fabrics to make clothes after a certain number of friction, its color changes relative. For the most obvious example, we can look at their clothes cuff is not better than the rest of the clothes should be dark, it is because when we usually work, cuffs often friction to occur with the desktop, so when the number of friction more , the amount reaches a certain amount of it caused a qualitative change, also opposing cuff color change. Of course in addition to cuffs, clothes can also occur elsewhere in this issue, because this dry friction aside, we often encounter another situation that wet friction. In this case we see more, our new clothes to buy back, scrub it for the first time, good quality may be better, if poorer quality that may be able to stain the water. Of course, even if escaped this time, after several scrub clothes or will fade more or less, the specific reasons we do not explain.
      As a leader in the textile equipment industry, Changzhou Shuanggudunda Electromechanical Technology Co., Ltd.. For this problem, research and development and production of a Y571B type friction color fastness instrument, which instrument is mainly used for various types of colored textiles resistant to dry and wet rubbing tests for color fastness and a variety of chemical fiber cotton, pure or blended spinning and dyeing cloth brushing color fastness test, performance in line with GB / T3920, and can function with brushing, you can say the operation is simple and fast.
