1 Scope This part of FZ/T 01057 specifies the test method for identification of textile fibers, i.e., density gradient column method. This part is applicable to the identification of various textile fibers, but not applicable to hollow fibers. 2 Normative references The following normative document contains provisions which, through reference in this part of FZ/T 01057, constitute provisions of this part. For dated references, subsequent amendments (excluding corrections), or revisions, of any of these publications do not apply to this part. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest editions apply to this part. FZ/T 01057.1 Test method for identification of textile fibers—Part 1: General introduction 3 Principles Since different fibers vary in density, the type of an unknown fiber may be determined by measuring its density and comparing it with those of the known fibers. If the mixture of two kinds of liquid with different densities but miscible with each other was injected into a gradient tube at a certain flow rate, the liquid will finally form a gradient density liquid column with the density increasing continuously from the top to the bottom, due to the diffusion of liquid molecules. Calibrate the density gradient of the liquid column by using glass balls with standard density, draw the relation curve of the ball density and the liquid column height (which shall conform to linear distribution), put the fiber balls to be measured into the density gradient tube, and after the balls remain stationary, the height where the balls stay may be used to determine the density of the fiber by checking the density-height curve.
