Detailed Description
The embodiments of the present utility model will be described more fully hereinafter with reference to the accompanying drawings, in which the structures described in the following embodiments are shown by way of illustration only, and the structures according to the present utility model are not limited to the structures described in the following embodiments, but all other embodiments obtained by one skilled in the art without making any inventive effort are within the scope of the present utility model.
Referring to fig. 1-2, the utility model provides a unidirectional easy-tearing water-absorbing composite material, which comprises a non-woven fabric composite layer, and is characterized in that: the non-woven fabric composite layer comprises a first spunlaced non-woven layer 1, spunbonded long fibers 2, a water absorption layer 3, an elastic net 4 and a second spunlaced non-woven layer 5 from top to bottom, wherein the elastic net 4 is of an orthogonal fiber structure, and the strength of the first fibers 31 in the transverse direction is higher than that of the second fibers 32 in the longitudinal direction.
Specifically, the elastic net is a combination of POE and TPV, and the strength of the first fiber 31 in the transverse direction is higher than that of the second fiber 32 in the longitudinal direction, i.e. the second fiber arranged in the longitudinal direction is easier to break, so that the material is easy to tear in the transverse direction, and the first fiber in the transverse direction of the orthogonal elastic net plays a more guiding role, so that the material has better unidirectional easy-to-tear performance.
In the water-absorbing design, the water-absorbing layer 3 is arranged on one side or two sides of the elastic net 4, in this embodiment, on one side, and the water-absorbing layer is one or more of wood pulp fiber, cotton fiber, PLA and PVA.
The water-absorbing layer is made of wood pulp fiber, cotton fiber, PLA and PVA, and has the characteristics of strong water absorption, so that the composite material has better water absorption effect.
Wherein, PLA (polylactic acid) is a novel biodegradable material and is prepared from starch raw materials proposed by renewable plant resources (such as corn). The starch material is saccharified to obtain glucose, and glucose and certain strain are fermented to prepare high purity lactic acid, and the polylactic acid with certain molecular weight is synthesized through chemical synthesis. The material has good biodegradability, can be completely degraded by microorganisms in the nature after being used, finally generates carbon dioxide and water, does not pollute the environment, is very beneficial to protecting the environment, and is a recognized environment-friendly material
PVA (polyvinyl alcohol) is a better water-absorbing material, has extremely strong water-absorbing capacity and water-supplying capacity, and does not drip after absorbing water.
In the structure compounding, the first spunlaced nonwoven layer 1 and the second spunlaced nonwoven layer 5 are soft microfibers, and GP velvet is particularly preferred.
In addition, in the process of hydroentanglement, the antibacterial agent is blended into the material, so that the material has better antibacterial performance.
