摘要：

为开发优质防羽面料,探明孔径及其分布特征对防羽面料性能的影响机制,借助多功能孔径测定仪、透气量仪和防钻绒性能测试仪获取10种不同规格防羽面料的孔径、透气率和钻绒根数,分析了孔径及其分布特征与透气性和防钻绒性之间的关系。结果表明:防羽面料的孔径分布符合正态分布的规律,且孔径均值和标准差的相关系数为0.99;在原料和组织结构相同的情况下,防羽面料透气率随着孔径均值的减小而减小;钻绒根数与孔径均值拟合方程的判定系数为0.94,当孔径均值小于8 μm时,面料的钻绒根数低于23根;提出采用透钻比(透气率和钻绒根数的比值)综合评价防羽面料的防钻绒性和透气性发现,透钻比与孔径变异系数呈显著负相关,即孔径变异系数越小,透钻比越大,面料的综合性能越好。

Abstract:

In order to develop high-quality down-proof fabrics, and explore the impact mechanism of pore size and distribution characteristics on down-proof fabric, the pore size, permeability and down-proof performance of 10 types of different down-proof fabrics were tested by capillary flow porometer, permeability meter and anti-drilling property tester. The relations between the pore size and distribution characteristics and the breathability and anti-drilling property of the down-proof fabrics were analyzed. The results show that the pore size distribution follows well the normal distribution, and the correlation coefficient between the mean aperture and standard deviation is 0.99. For the down-proof fabrics with the same material and structure, the permeability decreases when the mean pore size gets smaller. The determination coefficient of the fitting equation between the number of pile bored and the mean pore size is 0.94. When the mean pore size is less than 8 μm, the number of drill down penetrating fabric is less than 23. The breathability to drilling ratio (the ratio of permeability and the number of drilled down) is proposed to evaluate comprehensive the anti-drilling property and breathability. It is found that the less the pore size variation coefficient is, the larger the breathability to drilling ratio becomes, and the better comprehensive performance the fabrics have.

Key words: down-proof fabric, pore size distribution, breathability, anti-drilling property, breathability to drilling ratio
