In the actual use and washing process of the fabric, due to the constant friction on the surface, the fibers on the surface of the fabric are exposed to the surface of the fabric, forming a layer of fluff on the surface of the fabric. This phenomenon is called fuzzing.  If these hairy antlers do not fall off during subsequent use, they will become entangled with each other and form many spherical particles, commonly known as pilling.  These fur balls protruding on the surface of the fabric are easy to adhere dirt and dust, which seriously damages the wearing performance and appearance of the fabric.  It can give a judgment level for the fuzzing and pilling performance of fabrics, which will facilitate the selection of suitable fabrics in different environments.  In order to evaluate the anti-pilling performance of the fabric surface conveniently, a professional rating box shall be used for evaluation. The rating box shall be illuminated with white cathode fluorescent lamp or bulb to ensure uniform illumination of the sample, and at the same time, the observer shall not look directly at the light. The position of the light source shall be kept at 5 ~ 15 degrees from the plane of the sample, the observation direction shall be kept at 90 + 10 degrees from the surface of the sample, and the distance between the eyes with normal vision correction and the sample shall be 30 ~ 50 cm.

    The multi-station rating box developed by Wenzhou fangyuan instrument co., ltd. meets the requirements of GB/T 4802.3. on the premise of ensuring the accuracy of rating, it improves the rating efficiency and can save a lot of time.  FFZ902 multi-station rating box
