无纺布没有经纬线，剪裁和缝纫都非常方便，而且质轻容易定型。非织造布突破了传统的纺织原理，并具有工艺流程短、生产速率快，产量高、成本低、用途广、原料来源多等特点。
There are no warp and weft threads in non-woven fabrics. They are very convenient for cutting and sewing. They are light and easy to set. Nonwovens break through the traditional textile principle, and have the characteristics of short process flow, fast production rate, high yield, low cost, wide use, and many sources of raw materials.
与纺织布相比强度和耐久性较差，而且不能像其他布料一样清洗。因为纤维按一定方向排列，所以容易从直角方向裂开等等，因此生产方法的改善主要放在防止分裂的改良上。
Compared with textile cloth, strength and durability are poor, and can not be washed like other fabrics. Because the fibers are arranged in a certain direction, it is easy to split from the right angle and so on. Therefore, the improvement of production methods mainly focuses on the improvement of preventing splitting.
