研究了纱线加捻和去捻对织物舒适性的影响。已生产出23支、669转/米的棉纱和15支、827转/米的棉纱。又生产出866转/米、945转/米的特克斯纱23支，捻度1024转/米、1103转/米的特克斯纱15支，比标称纱线多捻度197转/米、多捻度276转/米。将23tex和15tex纱线中的多余捻度进行去捻处理，得到捻度分别为669转/米和827转/米的改性纱线。平纹针织物由改性纱线和标称纱线制成，然后漂白。测量了标称织物和改性织物的尺寸性能、透气性、透气性、排汗性和织物压缩性。最后，对标称材料和改性材料的舒适性进行了比较。加捻和去捻工艺使改性纱线的纱线直径增大，纱线柔软度提高，抗弯刚度降低，纱线强度与公称纱线相比没有变化。改性可增加织物厚度、密闭性、排汗高度和可压缩性。但织物的针脚密度、透气性和透气性均有所降低。
Effect of yarn twisting and de-twisting on fabric comfort has been studied. Cotton yarns of 23 tex with 669 turns/m and 15 tex with 827 turns/m have been produced as nominal yarns. Another 23 tex yarn has been produced with 866 turns/m and 945 turns/m along with 15 tex yarns with twist of 1024 turns/m and 1103 turns/m, with excess twist of 197 turns/m and 276 turns/m than the nominal yarn. The excess twists in the 23 tex and 15 tex yarns are then removed by de-twisting process which results in yarns with twists of 669 turns/m and 827 turns/m respectively, called modified yarns. Plain knitted fabrics are produced from both modified and nominal yarns and then bleached. The dimensional properties, air permeability, water vapor permeability, wicking and fabric compressibility are measured for nominal and modified fabrics. Finally, comparison of comfort characteristics is made between the nominal and the modified materials. The twisting and de-twisting process made the modified yarns to have higher yarn diameter, softness and less flexural rigidity without any change in yarn strength as compared to nominal yarns. Modification increases fabric thickness, tightness factor, wicking height and compressibility. However, stitch density, air permeability and water vapor permeability of the modified fabrics are found to be reduced.
