To investigate the contribution of yarn pore size distribution to fabric pores structure, in this paper, based on the balance relationship between the capillary height and the hydrostatic pressure of the liquid in the yarn, we designed and assembled a device for measurement of μm scale pore size distribution of the cotton yarn. Through comparison and analysis of data and considering the very low water content in the yarn, we increased the number of yarn, designed a special cutting device and improved the measurement accuracy of weight. Finaly, we obtained histograms and curves with highly accurate (0.0001g) and good reproducibility. The results show that the yarn pore size is in tens-hundreds μm and displays a concave-like distribution, while the fabric pore size change is much more complex, suggesting that the pore in the fabric is not a simple summation of the pore in the yarn.
