Abstract:

The wicking property of fabric can be controled by changing weave structure because of the effect of weave structure and fiber content on capillary size and its distribution. Employing the weight classification method, the pore size distribution of five woven cotton and polyester/cotton fabrics with different weaves was determined respectively. The effect of yarn density, warp density，weft density and fiber content on pore size distribution curve was investigated. The results showed that all the pore size distribution curves consist of four regions. With the decreas of the yarn density, the pore size region is extended with slight increase in the small pore size, significant increase in the big one, and considerable decrease in the amount of the maximum ratio pore size. Decreasing the warp density and weft density, the compression and merger of some typical regions occur, and pore size distribution tends to be more simple and uniform. Fiber content has little effect on the characteristic shape of the pore size distribution curve, except that slight compressed-extended deformation exhibits in some different regions.
