Evaluation on the measurement uncertainty of dimensional change of fabrics induced by free stream
Based on JJF 1059.1-2012,Evaluation and Expression of Uncertainty in Measurement,relevant mathematical model was established,the sources and components of the measurement uncertainty of dimensional change of fabrics induced by free stream were evaluated.The results showed that the synthetic uncertainty were 0.16％in warp direction,and 0.12％in weft direc-tion;its expanded uncertainty were 0.32％in warp direction and 0.24％in weft direction.Meanwhile,the results showed that the measurement uncertainty caused by random effect was the main factor of dimensional change of fabrics induced by free stream,which provided the basis for improving the accuracy of the measurement results.
