Description
technical field [0001] The invention relates to a textile testing instrument, in particular to a fiber density testing instrument. Background technique [0002] Density is an important parameter to characterize the physical properties of fiber polymer materials. Fiber density is of great significance to the study of fiber structure and physical indicators, and is also an important factor affecting the processing technology and application performance of fiber products. [0003] At present, the commonly used methods for measuring fiber density include density gradient method, liquid displacement method, floating and sinking method, pycnometer method and gas volume method, etc. [0004] (1) Density gradient method [0005] The principle of measuring fiber density by density gradient method is to mix two liquids with different densities but miscible with each other in a certain proportion and method, and use molecular diffusion to make the density of the mixed liquid gradually...
