And the areas with the longer fibers resonate with lower-frequency waves.

纤维较长的区域与低频波共振。

But suffice to say that carded fabrics are brushed and retain both long and short fibers giving them a softer feel.

但足以说明，梳理织物经过拉绒处理并保留了长纤维和短纤维，从而使它们手感更柔软。

Long, fine fibers can wrap around one another better than shorter, less fine fibers, which means those long, fine fibers make stronger threads that hang together better as fabric.

细长且高品质的纤维相较于短且质量较次的纤维，能更好地缠绕彼此。这表示那些细长且高品质的纤维能够制造出更坚韧的棉线，编织成更好的面料。
