Abstract
The utility model relates to a degradable sanitary towel with a alginate fiber core, which comprises a surface layer formed by organic cotton non-woven fabrics, a bottom film formed by polylactic acid materials and an absorption layer positioned between the surface layer and the bottom film; the absorption layer is a alginate fiber core. The alginate fiber is mainly used for preparing wound covering materials, and has excellent affinity to skin, so that the alginate fiber can help the wound to coagulate blood, absorb excessive secretion of the wound, keep the wound at a certain humidity and further improve the healing effect. Another characteristic of alginate fibres is their absorbency, which allows them to absorb 20 times their own volume of liquid, and their high absorbency allows them to absorb wound exudate, thus reducing microbial growth and possible off-flavours in the wound.
Description
Technical Field
The utility model relates to a sanitary towel field, more specifically say, relate to a degradable sanitary towel with alginate fiber 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 have poor adsorbability, bacteria are easy to breed, and healing is not facilitated.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a degradable sanitary towel with alginate fiber core.
The utility model provides a technical scheme that its technical problem adopted is: the degradable sanitary towel with the alginate fiber 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 a alginate fiber 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 alginate fiber core has following beneficial effect: the alginate fiber is mainly used for preparing wound covering materials, and the alginate fiber core body can help the wound to coagulate blood, absorb excessive secretion of the wound, keep the wound at a certain humidity and further improve the healing effect due to the excellent affinity of the alginate fiber core body to the skin.
Drawings
The invention will be further explained with reference to the drawings and examples, wherein:
fig. 1 is a schematic sectional structure diagram of a degradable sanitary napkin with an alginate fiber core in 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 alginate fiber 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 alginate fiber core.
The main application of the alginate fiber is to prepare a wound covering material. Because the alginate fiber core has excellent affinity to skin, the alginate fiber core can help the wound to coagulate blood, absorb excessive secretion of the wound, keep the wound at a certain humidity and further improve the healing effect.
After the alginate fiber covering material is contacted with the body fluid of a wound, calcium ions in the material can exchange with sodium ions in the body fluid, so that the alginate fiber material is changed into hydrogel from fiber, and the gel has hydrophilicity, so that oxygen can pass through and bacteria can be blocked, and further the growth of new tissues can be promoted, therefore, the alginate fiber material is comfortable to use on the wound, and the discomfort of the wound of a patient can be reduced when the dressing material is removed or replaced.
Another characteristic of alginate fibres is their absorbency, which allows them to absorb 20 times their own volume of liquid, and their high absorbency allows them to absorb wound exudate, thus reducing microbial growth and possible off-flavours in the wound.
The wound covering material made of the non-woven fabric made of all the alginate fibers combines high absorptivity and gelling property, so that a better wound healing environment can be provided, and therefore, the alginate fiber material can be used as a good medical material for clinical wound treatment.
Polylactic acid (PLA) is a novel biodegradable material, and takes starch extracted from non-grain crops (such as cassava, sugarcane, corn and the like) as a raw material. The starch raw material is saccharified to obtain glucose, the glucose and certain strains are fermented to prepare high-purity lactic acid, the polylactic acid with certain molecular weight is synthesized by a chemical synthesis method, and the polylactic acid can be completely degraded by microorganisms in nature after being used, so that carbon dioxide and water are finally generated, and the environment is not polluted.
Through 3 cores of absorbed layer only contain alginate fiber, do not contain the polymer, basement membrane 2 and outer envelope 5 are degradable polylactic acid material, and surface course 1 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 it is 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.
