Abstract
The utility model relates to a degradable sanitary towel with an organic cotton core, which comprises a surface layer formed by organic cotton non-woven fabrics, a bottom membrane formed by polylactic acid materials and an absorption layer positioned between the surface layer and the bottom membrane; the absorption layer is an organic cotton core. Through the absorbent layer core only contain the organic cotton, do not contain the polymer, basement membrane and outer envelope are degradable polylactic acid material, and the surface course also adopts the organic cotton material for can degrade naturally in soil after the sanitary towel is abandoned, can not bring the pollution for the environment, and be more healthy to the human body.
Description
Technical Field
The utility model relates to a sanitary towel field, more specifically say, relate to a degradable sanitary towel with organic cotton core.
Background
The absorption cores of the sanitary napkins on the market at present are generally of two types, one is a core of dust-free paper coated with fluff pulp and macromolecular water-absorbent resin; the other is a composite core body consisting of fluffy non-woven fabric, high polymer water-absorbent resin and dust-free paper.
Because the two cores contain macromolecules, the two cores cannot be naturally degraded after being abandoned, and great harm is caused to the environment.
Therefore, there is a need to develop a degradable absorbent core for solving the problem of environmental pollution caused by the non-degradable sanitary napkin in the prior art.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a degradable sanitary towel with organic cotton core.
The utility model provides a technical scheme that its technical problem adopted is: the degradable sanitary towel with the organic cotton core body is constructed, and comprises a surface layer formed by organic cotton non-woven fabric, a bottom film formed by polylactic acid material and an absorption layer positioned between the surface layer and the bottom film;
the absorption layer is an organic cotton core.
Preferably, the organic cotton nonwoven fabric is an organic pure cotton spunlace nonwoven fabric.
Preferably, the surface layer and the absorption layer and the bottom film are bonded through hot melt adhesives.
Preferably, the side of the bottom film, which faces away from the absorbing layer, is bonded with release paper through hot melt adhesive.
Preferably, one side of the release paper, which is far away from the bottom film, is provided with a degradable outer wrapping film.
Preferably, the outer coating is made of degradable polylactic acid.
Preferably, the release paper and the outer wrapping film are bonded through hot melt adhesive.
Implement the utility model discloses a degradable sanitary towel with organic cotton core has following beneficial effect: through the absorbent layer core only contain the organic cotton, do not contain the polymer, basement membrane and outer envelope are degradable polylactic acid material, and the surface course also adopts the organic cotton material for can degrade naturally in soil after the sanitary towel is abandoned, can not bring the pollution for the environment, and be more healthy to the human body.
Drawings
The invention will be further explained with reference to the drawings and examples, wherein:
fig. 1 is a schematic sectional view of a degradable sanitary napkin with an organic cotton core according to an embodiment of the present invention.
Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the degradable sanitary napkin with an organic cotton core in a preferred embodiment of the present invention comprises a surface layer 1 formed of organic cotton non-woven fabric, a bottom film 2 formed of polylactic acid material, and an absorbing layer 3 located between the surface layer 1 and the bottom film 2, wherein the absorbing layer 3 is an organic cotton core.
The organic cotton is pure natural pollution-free cotton, chemical products are not allowed to be used in agricultural production, and the spunlace non-woven fabric produced by the organic cotton has good air permeability, comfortableness and no sensitization, is beneficial to human health, has no pollution to the environment and can be naturally degraded; the absorbent core body prepared from the organic cotton does not contain water-absorbent resin and can be naturally degraded.
Polylactic acid (P L A) is a novel biodegradable material, and is prepared from starch extracted from non-grain crops (such as cassava, sugarcane, corn, etc.) by saccharifying starch to obtain glucose, fermenting with glucose and certain strains to obtain high-purity lactic acid, and synthesizing polylactic acid with certain molecular weight by chemical synthesis method.
Through 3 cores of absorbed layer only contain organic cotton, do not contain the polymer, basement membrane 2 and outer envelope 5 are degradable polylactic acid material, and surface course 1 also adopts organic cotton material for can degrade naturally in soil after the sanitary towel is abandoned, can not bring the pollution for the environment, and be more healthy to the human body.
The organic cotton non-woven fabric is organic pure cotton spunlace non-woven fabric, wherein high-pressure micro water flow is sprayed on one or more layers of fiber nets to enable the fibers to be mutually entangled, so that the fiber nets are reinforced and have certain strength, and the obtained fabric is the spunlace non-woven fabric.
The surface layer 1 and the absorption layer 3, and the absorption layer 3 and the bottom film 2 are bonded by hot melt adhesive, so that the bonding mode is stable, the environment-friendly requirement is met, and the skin is not irritated.
One side that basement membrane 2 deviates from absorbed layer 3 has from type paper 4 through the hot melt adhesive bonding, and one side that deviates from basement membrane 2 from type paper 4 is equipped with degradable outer envelope 5.
The outer wrapping film 5 is made of degradable polylactic acid, and the release paper 4 and the outer wrapping film 5 are bonded through hot melt adhesive.
It is to be understood that the above-described respective technical features may be used in any combination without limitation.
The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
