Abstract
Provided is a sanitary pad capable of complete degradation, comprising a surface layer, a liquid-isolating layer, a flow-guiding layer, an absorbing body, a bonding end, a small wrapping film and an outer packing bag. The surface layer and the liquid-isolating layer are fused by heat pressing or glued. The middle part of the upper end of a closing area of the surface layer and the liquid-isolating layer is provided with the flow-guiding layer, and the absorbing body is filled in the lower end of the flow-guiding layer. The sanitary pad capable of complete degradation is advantageous in that natural degradation of sanitary pads can be realized; pollution to natural environment can be reduced.
Description
[technical field]
This utility model relates to a kind of physiology nursing absorbent item, is specifically related to be applied to the gynecologic menstrual absorbent item, like sanitary towel, protective pad etc.; Adult and baby paper diaper; Nursing pad; A kind of physiology nursing of can degrading fully of pet pads etc. absorbs protective pad.
[background technology]
Physiology nursing absorbent item application is extensively like the gynecologic menstrual absorbent item, like sanitary towel, protective pad etc.; Adult and baby paper diaper; Nursing pad; Pet pads etc.This series products mainly is made up of top layer, absorber, separated liquid layer, independent packaging, outer bag etc.This series products belongs to the disposable product of promptly abandoning mostly; Because its top layer (non-woven fabrics commonly used and making hole film), separated liquid layer (being commonly called as notacoria or counterdie), independent packaging film and outer bag bag/film; All adopt the TPO processing of high molecular material to form at present, as: polyethylene (PE), polypropylene (PP) or its mixture are processed.Because it all derives from fossil feedstock, and be not easy to degrade under field conditions (factors), therefore, the source is more and more deficienter, simultaneously, very big to the injury of environment on the one hand.
[utility model content]
For solving above deficiency; This utility model provides a kind of physiology nursing of can degrading fully to absorb protective pad; It carries out comprehensively substituting to the unfriendly material of environment main in the existing product such as skin-material, separated alburnum material, individual packets dress and outer bag consumptive material; Make that being degraded to environmentally friendly rate under the natural conditions of product reaches more than 90%, becomes the product of environment-friendly type fully.
The technical scheme that this utility model adopted is: a kind of physiology nursing of can degrading fully absorbs protective pad and it is characterized in that; It comprises the top layer, forms at a distance from liquid layer, water conservancy diversion layer, absorber, bonding end, little peplos and outer bag; Top layer and separated liquid layer merge or gummed in bonding end hot pressing; Is the water conservancy diversion layer on the top layer with at a distance from liquid layer closed area upper end for the middle part, and absorber is filled in water conservancy diversion layer lower end.
Described a kind of physiology nursing of can degrading fully absorbs protective pad and it is characterized in that, described top layer is polylactic acid non-woven fabrics (comprising hot rolling, hot blast, water thorn, antiseized), polylactic acid making hole film and and the non-woven fabric compounded making hole film of polylactic acid (containing repeatedly punching).
Described a kind of physiology nursing of can degrading fully absorbs protective pad and it is characterized in that, described at a distance from liquid layer be the polylactic acid counterdie or with the composite membrane of polylactic acid non-woven fabrics, polylactic acid ventilated membrane or with the compound breath film of polylactic acid non-woven fabrics.
Described a kind of physiology nursing of can degrading fully absorbs protective pad and it is characterized in that described little peplos is polylactic acid film or the laminated film non-woven fabric compounded with polylactic acid.
Described a kind of physiology nursing of can degrading fully absorbs protective pad and it is characterized in that described outer bag is a polylactic acid film.
Described a kind of physiology nursing of can degrading fully absorbs protective pad and it is characterized in that described water conservancy diversion layer is polylactic acid non-woven fabrics or polylactic acid making hole film.
Described a kind of physiology nursing of can degrading fully absorbs protective pad and it is characterized in that described absorber is Time of Fluff Slurry and SAP (Super Absorbent Polymer High hydrophilous resin).
Described a kind of physiology nursing of can degrading fully absorbs protective pad and it is characterized in that the combination between described each functional layer adopts hot pressing to merge or gummed.
As everyone knows, polylactic acid (PLA) is a kind of novel biodegradation material, and it uses the starch material that reproducible plant resources (like corn and millet bar) is contained to process.Starch material is processed lactic acid via sweat, converts polylactic acid to through chemosynthesis again.It has good biodegradability, can be degraded fully by the occurring in nature microorganism after the use, finally generates carbon dioxide and water; Directly get into the soil organism or, can not enter in the air, can not cause greenhouse effect by plant absorbing; Simultaneously, also be reproducible recycled material.Simultaneously, polylactic acid has extraordinary biocompatibility, also is a macromolecular material as safe as a house.
Poly-lactic acid material is applied to hindered in the disposable physiological absorption articles for use always, on the one hand, polyphosphoric acid is processed embossed film, non-woven fabrics, making hole film and even the ventilated membrane that sanitary goods industry can be suitable for, technical elements lacks research always or is difficult to maturation.Simultaneously, since inter-trade, information each other and the also difficult application that realizes truly of technology.
Present technique; Utilize the technology of being grasped fully at aspects such as system film, making hole film and final products; The unfriendly material of environment main in the existing product such as skin-material, separated alburnum material, individual packets dress and outer bag consumptive material are carried out comprehensively substituting; Make that being degraded to environmentally friendly rate under the natural conditions of product reaches more than 90%, becomes the product of environment-friendly type fully.
This utility model beneficial effect: adopt the physiology nursing absorbent item of present technique can realize degrading under the natural conditions, reduce natural environment is endangered.
For making characteristic and the technology contents of further understanding this utility model, see this utility model accompanying drawing and embodiment for details, yet appended graphic only for reference and explanation usefulness is not to be that this utility model is limited.
[description of drawings]
Fig. 1 is this utility model structural representation;
Fig. 2 is a sketch map behind this utility model assembly packaging:
1-top layer among the figure; 2-water conservancy diversion layer; 3-is at a distance from liquid layer; The 4-absorber; The bonding end of 5-; The little peplos of 6-; The outer bag of 7-.
[specific embodiment]
Below in conjunction with accompanying drawing and specific embodiment this utility model is elaborated:
A kind of physiology nursing of can degrading fully as shown in the figure absorb protective pad its by top layer 1; Water conservancy diversion layer 2; At a distance from liquid layer 3; Absorber 4; Bonding end 5; Parcel film 6; 7 compositions of outer bag, top layer 1 and merge or gummed in bonding end 5 hot pressing at a distance from liquid layer 3, on the top layer 1 and be water conservancy diversion layer 2 at a distance from liquid layer 3 closed areas upper end for the middle part, absorber 4 is filled in water conservancy diversion layer 2 lower end.Above cellular construction overcoat parcel film 6, the outer bag 7 of several cellular construction assembling back overcoats.
