One-way easily-tearable water-absorbing composite material

The utility model relates to the technical field of textile, and discloses a one-way easily-tearable water-absorbing composite material which comprises a non-woven fabric composite layer, the non-woven fabric composite layer comprises a first spunlace layer, spun-bonded long fibers, a water-absorbing layer, an elastic net and a second spunlace layer from top to bottom, the elastic net is of an orthogonal fiber structure, and the second spunlace layer is of a non-woven fabric structure. The transverse first fiber strength is higher than the longitudinal second fiber strength. According to the scheme, due to the design that the strength of the first fibers of the elastic net fibers is higher than that of the second fibers in the longitudinal direction, the non-woven fabric composite layer can be broken by silk more easily in the transverse direction, and therefore the non-woven fabric composite layer can be torn off in an oriented mode more easily and can be torn off in an oriented mode according to the using l
