Study on Downproofness of Down Home Textile Fabrics

In order to study the downproofness of down home textile fabrics, there are 10 kinds of fabrics which belong to A and B two series were woven. They were interwoven with different yarns e.g. cotton and DTY. Air permeability and downproofness of the fabrics were tested and analyzed. The relationship between the weft density, tightness, air permeability and downproofness was achieved. From the test results, following conclusions can be gotten. 1) Within a certain range, the air permeability is enhanced as weft density and tightness of fabrics are decreased; 2) The downproofness is good for fabrics with higher weft density; 3) The downproofness is good for fabrics with larger tightness; 4) From the analysis of linear regression, the downproofness and air permeability of the fabrics are negatively related, which means that good air permeability indicates poor downproofness of the fabrics.
