The Efficient Usages of the Interlinings for the Clothing in the Cold Districts

为了在寒冷的气候条件下有效地利用衬布，进行了这项研究。研究了以机织面料和衬布为组成成分的双层织物。对衬布的最终使用性能进行了研究，结果表明：(1)织物表面较粗糙、结构较疏松的织物，其R和外阻R_2较大；(2)双层织物的R和R_2必须通过层压织物的粘合降低。推测机织物与衬里之间的夹气层对内阻R_1和R_2的大小起着重要作用。分层织物的R与分隔组成成分的5 mm厚度的附加空气层相关的增加必然小于5 mm。结构越紧凑的面料，R_1的增加幅度越大。比较了20种机织物在0.9m/s和0.3m/s湍流条件下的R值。在0.9米/秒中的R不可避免地小于在0.3米/秒中。当风速为0.9m/s时，R对织物覆盖系数的依赖性较小。R显著降低，透气性增加0.9m/s。比较了27种商品衬布经十次家居洗涤与单纯水浸处理后最终使用性能的变化。结果表明，水处理对材料性能的影响较大。

For the standpoint of the efficient usage of the interlinings in the cold climate, this study was performed. R for two-layered fabrics using a woven fabric and a interlining as constituent components was studied. Also, the end-uses properties of the interlining were studies.The results obtained were as follows:(1) R and the external resistance R_2 of the woven fabrics having the rougher surface and the looser structure were larger for the woven fabrics.(2) R and R_2 of the two-layered fabrics were necesarily decreased by means of adhesion for the laminated fabrics. It was assumed that the entrapped air layer between the woven fabric and the interlining played an important role in the values of both the internal resistance R_1 and R_2.(3). The increase in R of the layered fabrics associated with a thickness of 5mm of additional air layer separating the constituent components was necessarily smaller than 5mm. The increase in R_1 was larger using the face fabrics having the tighter structure.(4). R of the 20 Kinds of the woven fabrics in turbulunt flow of 0.9 m/sec was compared with that of 0.3 m/sec. R in 0.9 m/sec is inevitably smaller than in 0.3 m/sec. Also, the wind velocity of 0.9 m/sec gave the smaller depencence of R on the cover factor of the fabrics. R remarkably decreased woth an increase in air permeability in 0.9m/sec.(5). The changes in the end-uses properties of the 27 kinds of commercial interlinings by ten times repeated home laundry were compared with those by the simple water-immersion treatment. It was noted that the water-treatment occured the larger extent of the change in the properties.
