In order to overcome the defects of the prior art, the utility model provides a seepage-proofing sanitary material infantees, seepage-proofing sanitary material infantees wet attitude powerful is greater than 10N 5cm, wet attitude elongation is greater than 20%, seepage-proofing sanitary material infantees toughness is good, the wet attitude is difficult damaged, the anti-infiltration volume is less than 2g, seepage-proofing sanitary material infantees frivolous gas permeability is good, seepage-proofing sanitary material infantees thickness is less than 0.35mm, the gas permeability is greater than 40mm/s, can be applied to the sanitary products such as production menstrual period safety trousers, infant pull-up trousers, adult incontinence trousers.

The above object of the present invention is achieved by the following technical solutions:

an impermeable sanitary material wrapping cloth comprises a cellulose fiber layer and a chemical fiber layer, wherein the top layer is the cellulose fiber layer, and the bottom layer is the chemical fiber layer; the impermeable sanitary material wrapping cloth is a non-woven cloth with a double-layer structure formed by sequentially laying a cellulose fiber layer and a chemical fiber layer from top to bottom;

the gram weight of the impermeable sanitary material wrapping cloth is 15-55 g/m²。

The cellulose fiber layer mainly plays a role in quickly absorbing and locking liquid, and the gram weight of the cellulose fiber layer is 7.5-27.5 g/m²。

The chemical fiber layer mainly plays a role in increasing strength and preventing liquid reverse osmosis, and the gram weight is 7.5-27.5 g/m²。

The cellulose fiber layer is made of 65-99% of pulp fibers and 1-35% of ultrashort-cut fibers containing high liquid absorption factors, the length range of the pulp fibers is 1-6 mm, and the length range of the ultrashort-cut fibers containing high liquid absorption factors is 2.5-19.5 mm.

The chemical fiber layer is made of one or a combination of multiple chemical fibers such as polyester fibers, polypropylene fibers, polyethylene fibers, polyamide fibers, vinylon fibers, polylactic acid fibers and animal and plant polyester fibers, and the length range of the chemical fibers is 6-76 mm.

The utility model provides a pair of anti-seepage sanitary material wrapping cloth which is applied to sanitary products, such as menstrual safety pants, infant pull-ups, adult incontinence pants and the like.

Compared with the prior art, the utility model beneficial effect be: the utility model provides a cellulose fiber layer of the impermeable sanitary material wrapping cloth, which consists of pulp fiber and ultrashort cut fiber containing high liquid absorption factor, the wrapping cloth has good liquid absorption and locking effects, the liquid absorption amount is higher than that of the product with the same specification in the market, but the reverse osmosis amount is lower than 2 g; compared with products with the same specification in the market, the chemical fiber layer has the advantages that the strength can be obviously increased, the reverse osmosis of liquid can be prevented, the wet strength is greater than 10N/5cm, the wet elongation is greater than 20%, the toughness is good, and the wet fiber layer is not easy to damage; the coated fabric has a gram weight of 7.5 to 27.5g/m²The thickness is less than 0.35mm, the air permeability is more than 40mm/s, and compared with products with the same specification in the market, the product is light, thin and better in air permeability, and can be applied to producing sanitary products such as menstrual safety pants, infant pull-ups, adult incontinence pants and the like.
