Abstract
The purpose of the study was to evaluate the surface and pore characteristics of the wool fabrics. The fabrics used for the study were 100fo wool fabrics woven with variation of weft density, weaving structure, and linear density. Their surface characteristics and mean pore diameter were measured. The results of the study were as follows: 1) Mean Pore diameter (MPD) of the samples increased with decreasing cover factor and weft density, and increasing surface roughness (SMD). It showed that MPD of 30's, single yarn, and plain fabrics were lam or 2) MPD of the samples increased with water vapor transmission rate and air permeability of the samples. 3) Coefficient of friction (MIU) of the samples decreased with increasing bulk dencity and weft density. It showed that MIU of 40's, folded yarn, and satin fabrics were lower In addition, MIU of the samples increased with keeping warmth ratio. 4) SMD of the samples decreased with increasing cover factor and weft density. It showed that SMD of 40's, folded yarn, and satin fabrics were lower. 5) As SMD of the samples increased, there were lots of larger pore in the structure, and thus water vapor transmission rate and air permeability of the samples increased.
