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

从衬布在寒冷气候条件下的有效利用角度出发，进行了该项研究。研究了以机织物和衬布为组成成分的双层织物的R。并对衬布的最终用途特性进行了研究。结果表明：(1)表面较粗糙、结构较松散的机织物的R和外阻R_2较大。(2)层压织物的粘合作用必然降低两层织物的R和R_2。假设机织物与衬布之间的夹持空气层对内阻R_1和R_2的取值都有重要影响。层状织物的R的增加与分隔组分的额外空气层厚度5mm有关，必然小于5mm。使用结构更紧密的面织物，R_1的增加幅度更大。对20种机织物在0.9 m/sec湍流中的R与0.3 m/sec湍流中的R进行了比较。0.9米/秒的R必然小于0.3米/秒的R。此外，风速为0.9 m/s时，R对织物遮盖系数的依赖性较小。在0.9m/sec时，R随透气性的增加而显著降低(5)。比较了27种商用衬布经10次重复家庭洗涤后与单纯浸水处理后的最终使用性能变化。结果表明，经水处理后发生的性能变化程度较大。

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.
