The invention discloses non-woven cloth. The non-woven cloth is prepared from hot melt adhesive short fibers and super absorbent short fibers with crimpiness and thermoplasticity as materials in manners of carding, wet forming and drying by hot air. According to the weight percentage of the non-woven cloth, the content of the super absorbent short fibers with crimpiness and thermoplasticity is 2-75wt%; the content of the hot melt adhesive short fibers is 25-98wt%; the multiplying power of the non-woven cloth for absorbing distilled water is 12.5-40.2g/g; the multiplying power of absorbing normal saline is 8.7-31.9g/g; the grams per square meter of the non-woven cloth is 10-30g/m<2>; and the breaking strength of the non-woven cloth which is 50mm in width is 8-26N. The non-woven cloth is used for an absorbed layer or a moisture absorption core body of a one-time hygroscopic material. The invention also discloses a preparing method of the non-woven cloth.
