本文研究了15种棉、粘胶、醋粘、尼龙针织物在洗涤过程中尺寸变化与织物结构变化的关系。织物包括每英寸24、28、32、36、40和44横列的平纹和罗纹针织物，以及每英寸24、28和32横列的联锁针织物。将整理织物和坯布在洗涤前后的几何形状与已经接受手动再洗涤处理的相同织物的几何形状进行比较。对纵行和横列间距的测量表明，洗涤使未松弛的织物结构发生了相当大的重排。纵行与横列间距的数据遵循抛物线的洗涤织物和所有松弛织物。经松弛处理后的织物，洗涤前后的横列间距和纵行间距均呈线性关系。松弛织物的长度、宽度和面积的尺寸变化通常不大于10%，并且经常小于5%。整理后织物的面积变化随针织硬挺度的变化而变化，但经松弛处理后，面积变化较小，不受针织硬挺度的影响。
The dimensional changes in laundering of 15 fabrics knit from cotton, viscose, acetate- viscose, and nylon yarns were investigated in relation to changes in fabric structure. The fab rics included plain and rib knit of 24, 28, 32, 36, 40, and 44 courses per inch, and interlock knit of 24, 28, and 32 courses per inch. The geometry of both finished and gray fabrics before and after laundering was compared to the geometry of the same fabrics which had received a manual re laxation treatment. Measurements of wale and course spacings showed that laundering brought about considerable rearrangement in the structure of the fabrics which had not been relaxed. The data for wale versus course spacings followed parabolic curves for the laundered fabrics and for all relaxed fabrics. The relation of the course spacings before and after laundering and of the wale spacings before and after laundering was linear for the fabrics given the relaxation treatment. Dimensional change in length, width, and area of the relaxed fabrics was usually not greater than 10%, and often less than 5%. Changes in area varied markedly with the knitting stiffness of the finished fabrics, but after relaxation treatment, the changes were small and were not influenced by the knitting stiffness.
