Zusammenfassung: | The invention provides a method for judging Lyocell short fiber dyeing uniformity. The method comprises the following steps that: selecting a reference sample, selecting an inspection lot dyeing sample, carrying out sample preparation, preparing dye mother liquor and dyeing accelerant mother liquor, dyeing, washing, drying, measuring a total color difference, carrying out result assessment and blending. By use of the method, machine dyeing is adopted, so that a dyeing process is controllable, and dyeing detection time is 4-5h. Result judgment adopts an instrument method, so that operation is simple, and color judgment is accurate and quick. The short fiber of which the uniformity is judged through laboratory dyeing can be used for producing high-end textiles, the color difference, which iscaused by dyeing unevenness, of a terminal textile product can be avoided, the uniformity of the product is further improved, and the additional value of the product is greatly improved.
