Abstract
The utility model relates to a completely-biodegradable sanitary napkin, belonging to the field of hygienic products. The completely-biodegradable sanitary napkin comprises a surface layer, a diversion layer, a water absorbing layer, a basal membrane layer, a release paper layer and an outer envelope layer, wherein the surface layer made of degradable nonwovens is an uppermost layer, and the lower surface of the surface layer is glued with the diversion layer made of the degradable nonwovens; the lower surface of the diversion layer is glued with the water absorbing layer made of high-polymer absorbent paper or wood pulp with a super absorbent high-polymer material, and the lower surface of the water absorbing layer is glued with the basal membrane layer made of PBAT biodegradable plastics; the lower surface of the basal membrane layer is glued with the release paper layer made of a degradable paper material; and the outer envelope layer made of the PBAT biodegradable plastic is arranged at the lower surface of the release paper layer. The completely-biodegradable sanitary napkin has the advantages of convenience in use and simple structure, all structural layers can be degraded, and white pollution cannot be generated. The completely-biodegradable sanitary napkin is a green product and is a substiture of the sanitary napkin.
Description
Technical field
This utility model relates to a kind of disposable personal hygiene article, relates in particular to a kind of complete biodegradable sanitary towel, belongs to hygiene article sector.
Background technology
The 1980s, China begins production and sales gynecologic menstrual sanitary towel, and most gynecologic menstruals that are through with use the history of sanitary pad (or toilet paper).Gynecologic menstrual sanitary towel comprises that also baby diaper, adult diaper, mattress etc. defend the year sales volume of article and enhance year by year, and China gynecologic menstrual sanitary towel sales volume in 2010 is 26,000,000,000 of 54,000,000,000, sanitary pad according to the statistics made by the departments concerned.Common sanitary towel has solved comrade's women menstrual hygiene problem, and uses and handle inconvenience.Through nearly 30 years development, the materials used of China sanitary towel is plastics such as PE, PP and other composites, all is to use non-degradable material, thereby brings great white pollution to natural environment simultaneously.Therefore; The international and domestic manufacturer that defends the article industry; Actively drop into the material that article are defended in the lot of manpower and material resources research and development, wherein degradable or Wholly-degradable material be current environmental protection the most, the green material that has development prospect most, but also form the degradable napkin of producing in batches at present.
The utility model content
This utility model provides a kind of complete biodegradable sanitary towel easy to use simple in structure.
The technical scheme that this utility model adopts is: this complete biodegradable sanitary towel comprises surface layer, water conservancy diversion layer, water accepting layer, basal membrane layer, off-style paper layer and outsourcing rete; Surface layer is the superiors, gluing water accepting layer below the gluing water conservancy diversion layer below the surface layer, water conservancy diversion layer; Gluing basal membrane layer below the water accepting layer; Be provided with the outsourcing rete below the gluing off-style paper layer below the basal membrane layer, off-style paper layer, it is simple in structure easy to use.
Further; Surface layer and water conservancy diversion layer are processed by degradable nonwoven fabrics; Water accepting layer adds the super absorbent polymer material by macromolecule water uptake paper or wood pulp to be processed, and off-style paper layer is processed by the degradable paper material, and basal membrane layer and outsourcing rete are processed by the PBAT biodegradable plastics.Because each structure sheaf all adopts the material of fully biodegradable to process, so its environmental protection does not produce white pollution.
The utlity model has and common PE, PP, the equal water absorbent rate of SPA composite sanitary napkin; Easy to use; Hygiene and health; And make with completely biodegradable material, not only can not cause any harm, international and domesticly want for many years to solve and unsolved white pollution problems and efficiently solve to environment.
Description of drawings
Fig. 1 is a complete biodegradable SANITARY NAPKIN CONSTRUCTION sketch map.
Labelling is following among the figure: the 1-surface layer; 2-water conservancy diversion layer; The 3-water accepting layer; The 4-basal membrane layer; The 5-off-style paper layer; 6-outsourcing rete.
The specific embodiment
In order to understand the technical characterstic of this utility model better, this utility model is done explanation further below in conjunction with accompanying drawing.
As shown in Figure 1, surface layer 1 is the superiors, and surface layer 1 directly contacts with human body, and mostly the surface material that is now adopted on the market is the PE production of articles, does not have degradability, and the surface layer 1 of this utility model adopts degradable nonwoven fabrics to process; The gluing water conservancy diversion layer of processing by degradable nonwoven fabrics 2 below the surface layer 1, water conservancy diversion layer 2 is in order to prevent the liquid reverse osmosis and to promote that liquid better absorbs; Gluingly below the water conservancy diversion layer 2 add the water accepting layer 3 that the super absorbent polymer material is processed by macromolecule water uptake paper or wood pulp; This high molecular material of high water absorption can be selected SAP for use; It is hydroscopic high-molecular resin; The gluing basal membrane layer of processing by PBAT (gathering adipic acid/butylene terephthalate) biodegradable plastics 4 below the water accepting layer 3, basal membrane layer 4 is in order to prevent fluid seepage; The gluing off-style paper layer of processing by the degradable paper material 5 below the basal membrane layer 4; After the release paper of peeling off on the off-style paper layer 5; Stay the glue on the basal membrane layer and can be used to locate product; Make product be bonded on the clothes and can not move, be provided with the outsourcing rete of processing by degradable nonwoven fabrics 6 below the off-style paper layer 5.Outsourcing rete 6 wraps up other layer, thereby serves as outer package.Wherein basal membrane layer and outsourcing rete form through film-blowing process.
