Abstract:

In view of the method to investigate the dry state of textile material awaiting measurement by testing the air humidity of oven and the fact that the non-linear regression equation model established on textile material quality difference between pre-and post-weighing and the frequency difference between the two leads to greater error, this paper proposed to establish a gray system GM(1,2) based on the air humidity of oven and the moisture regain of textile material being dried. The fitting error of which has been proven to be much smaller than that of the regression equation model, and it can satisfy the requirement of engineering calculating. Thus, it provides a necessary solution in measuring the air humidity of oven showing dry state of textile material awaiting measurement.
