The purpose of this utility model is exactly can discharge because of body fluid is a large amount of suddenly for the product that overcomes the absorption human secretion that existing fit skin-material makes to cause along fit surperficial overflow, pollute medicated clothing or cause local imbibition saturated and shortcoming such as overflow because of having little time to expand to ooze, and designs a kind of porous membrane cloth with guiding gutter with unique water conservancy diversion and liquid permeability energy.
This utility model is realized by following structure technology scheme: have guiding gutter porous membrane cloth structural representation as shown in Figure 1, it is shaped as cuboid, it is made of jointly thin film cloth 1, guiding gutter 2, through hole 3, its interconnected relationship is: the single or double of thin film cloth 1 has the ripple guiding gutter 2 of crooked shape or vertical bar shaped, the depth D of guiding gutter should be 0.15＜D/W＜2.5 with the ratio of width of rebate W, has a plurality of tiny through holes simultaneously at guiding gutter bottom land or bottom land, groove body.Wherein, thin film cloth can be high molecular polymer thin film, non-woven fabrics or stationery, also can be the complex or the dipping body of metal forming, metal coating and mentioned kind material.Its action principle is: the ripple guiding gutter is used for the moving direction of limitative aspect liquid stream, promptly play the water conservancy diversion humoral effect, to prevent that body fluid is along fit surperficial overflow, and body fluid is distributed as far as possible by the direction that guiding gutter limited, thereby avoid the body fluid can excessive certain position that concentrates on the absorb body fluids product, cause the saturated and seepage of this position suction wicking liquid.Through hole plays the infiltration humoral effect, so that body fluid arrives the suction core, thereby is held by the absorbent material suction.
1., during with the product of this thin film cloth manufacturing absorption human secretion this utility model---porous membrane cloth with guiding gutter is used to make the fit skin-material of product that absorbs human secretion and compares and have following advantage and beneficial effect with existing:, because body fluid can be directed into this product two ends length direction, just can make full use of imbibition material to greatest extent, therefore can reduce the consumption of imbibition material, not only can reduce cost, and can make product thinner, the user uses more convenient; 2., make to absorb the human secretion product with this thin film cloth---as sanitary towel etc., because body fluid is drawn towards the product end positions, can prevent the local supersaturation imbibition in stage casing and cause the side seepage, simultaneously owing to do fit top layer with this thin film cloth, body fluid horizontal mobility resistance is increased, thereby overcome the shortcoming that the side overflow often takes place in existing sanitary towel: 3., because this utility model particular structure characteristics, make product with this thin film cloth---as sanitary towel etc., because fit top layer and human body skin are actual contacted to be the seamed edge of this utility model guiding gutter, make between skin and the thin film cloth more space is arranged, more help flowing of air and body fluid, thereby can keep skin that dry and comfortable sensation is arranged.Because it is it is less with the contact skin area, few from the heat that skin spreads out of in addition in the moment that just contacts, touch the creeping chill that thin film brings thereby avoided generally skin to rigidly connect; 4., this utility model is of many uses, can be in order to make sanitary towel, diaper, wound dressing bag, Operating sheet, sickbed sheet, crash helmet inwall cushion or the like.When being used to make the fit cushion of inwall of crash helmet or rigid protection cover, the effect of its guiding gutter and through hole is the mediation air, quickens the volatilization of human body skin perspiration, can reduce and wear the sultry sensation that the helmet or protective cover bring; 5., this utility model processing simple in structure, easy, making.
Below Figure of description is further specified as follows: Fig. 1 is the structural representation with porous membrane cloth of guiding gutter.Among the figure: 1 for thin film cloth, 2 is that guiding gutter, 3 is that through hole, D are the guiding gutter degree of depth, and W is the guiding gutter width of rebate.
This utility model can be implemented by following manner: 1., with the method for existing manufacturing thin film, non-woven fabrics and technology production, make thin film, non-woven fabrics, perhaps buy thin film, non-woven fabrics finished product after, carry out the stretching of at least one direction then; 2., by the hot-forming guiding gutter of a pair of grooved bowl, wherein grooved bowl has the hard roll surface of with groove, another grooved bowl has the soft roll surface of rubber, after a pair of grooved bowl is hot-forming, just can extrude guiding gutter to thin film or non-woven fabrics; 3., wear the pressure through hole, wherein press the hole roller to have the prominent hard roll surface of point for one, and another press hole roller to have slick hard roll surface by a pair of pressure hole roller.Thin film or non-woven fabrics just can be made into the porous membrane cloth with guiding gutter behind a pair of grooved bowl and roller continuous hot-press molding of a pair of pressure hole and horse back cooling and shaping.If add man-hour, only need hot-forming guiding gutter, need not to wear again the pressure through hole with class thin film cloth such as the non-woven fabrics that self has through hole, impregnated papers.The inventor once just be made into by above-mentioned embodiment have slot opening W=1.5mm, the multi-through hole thin film cloth of groove depth and the two-sided straight trough of the ratio D/W=0.8 of slot opening.And utilize this porous membrane cloth with guiding gutter to be made into sanitary towel's sample as the fit top layer of sanltary towel, the length direction of this sanitary towel is consistent with the bearing of trend of guiding gutter.By " 3.5 permeance property " test method among the standard GB 8939-88 " sanitary towel " this sanitary towel sample is compared test with the sanitary towel that does fit top layer with polypropylene (PP) non-woven fabrics of no guiding gutter or polyethylene (PE) porous membrane that do not have a guiding gutter then, and the absorbent material of three samples, shape, size are in full accord, and test method is to inject fresh porcine blood with pipet to each sanitary towel center.Result of the test is as shown in the table:
