Abstract
The utility model relates to a kind of nonwoven fabric veil, especially a kind of double-deck nonwoven fabric veil, comprise the surface layer and the bottom that are mutually bonded together, orderly the arranging towards assigned direction of fiber of described surface layer, the unordered mixed and disorderly arrangement of fiber of described bottom, the smooth surface of bottom described in the surface ratio of described surface layer.Orderly the arranging towards assigned direction of surface layer fiber due to veil, for example, towards longitudinal arrangement, can flow away along the direction of fiber body fluid fast, and with respect to existing veil, its water conservancy diversion, water suction and osmotic effect are better, dryer and comfortableer during use.Due to the unordered mixed and disorderly sequence of the bottom fiber of veil, there is good obstruct and reverse osmosis effect again.
Description
Technical field
The utility model relates to a kind of nonwoven fabric veil, especially a kind of double-deck nonwoven fabric veil.
Background technology
At present, commonly on the market for making the nonwoven fabric veil of the products such as sanitary napkin, paper diaper, mainly adopt hot rolling, hot blast, spunbond, punching or use the techniques such as PE film to make, the fiber orientation of these fabrics is normally mixed and disorderly, or the orientation of fiber is not obvious, easily fluffing and gap are larger, in use, feature due to itself structure, ventilative general with dry and comfortable performance, liquid diffusion is bad, easily cause fash, the bad reaction such as allergic, and comfortableness is also not satisfactory.
Chinese invention patent ZL201310473717.3 discloses a kind of pearl type dimensional diversion trepanning dual layer nonwoven sanitary upper material, and at the three-dimensional salient point of the uniform pearl type of upper strata fabric fabricbase upper side, fabric fabricbase bottom, upper strata is provided with guide layer.By the groove between pearl shape protrusion, carry out receiving body fluids, then allow body fluid by pearl shape, protrude combination bore infiltration downside guide layer fast, the contact area of minimizing and human body skin, while making to use, surface dry is comfortable.But its salient point contacting with human body skin is still general veil structure, and the fiber orientation of its veil is mixed and disorderly, at contacting points position, still likely causes the bad reaction of skin.
Chinese utility model patent ZL20120646501.3 discloses a kind of fabric with diversion function, comprise fabric body, the first guide layer that the use face setting of fabric body is mixed into by ES fiber and fluffy fiber, the non-use face of fabric body also arranges the second guide layer being mixed into by ES fiber and fluffy fiber.By adopting the fabric being mixed into by ES fiber and fluffy fiber as guide layer, the bulkiness of product, diffusivity, crushing resistance excellence, liquid storage ability is largely increased, but the fiber orientation of its each layer remains mixed and disorderly, still has further improved space.
Utility model content
Dryer and comfortableer two-layer nonwoven veil when the purpose of this utility model is to provide a kind of water conservancy diversion, water suction and osmotic effect better and uses.
To achieve these goals, the utility model adopts following technical scheme:
A two-layer nonwoven veil, comprises the surface layer and the bottom that are mutually bonded together, and what the fiber of described surface layer was orderly arranges towards assigned direction, the unordered mixed and disorderly arrangement of fiber of described bottom, the smooth surface of bottom described in the surface ratio of described surface layer.
As of the present utility model a kind of preferred, described surface layer and described bottom are all strip, the fiber longitudinal arrangement of described surface layer.
As of the present utility model a kind of preferred, described surface layer and described bottom are interweaved and are bonded together by the fiber on each layer.
Adopt such scheme, the utlity model has following beneficial effect:
1, due to orderly the arranging towards assigned direction of surface layer fiber of veil, for example, towards longitudinal arrangement, body fluid can be flowed away fast along the direction of fiber, with respect to existing veil, its water conservancy diversion, water suction and osmotic effect are better, dryer and comfortableer during use.
2, due to the unordered mixed and disorderly sequence of the bottom fiber of veil, there is good obstruct and reverse osmosis effect.
3, due to surface layer fiber ordered arrangement, the horizontal stretching resistance of veil is on the low side, and the fiber lack of alignment of bottom has preferably laterally resistance to tension, by bottom and surface layer are bonded together, effectively raises the resistance to tension of whole veil.
4, the smooth surface of the surface ratio bottom of surface layer, surface layer is difficult for fluffing, more can obtain better pro-skin sense with skin contact, and Diazolidinyl Urea, can not play the effect of identification veil positive and negative simultaneously yet.
figure of description
Fig. 1 is the structural representation of the utility model two-layer nonwoven.
In figure, indicate corresponding as follows:
1-surface layer; 2-bottom.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the two-layer nonwoven veil of the present embodiment, comprises the surface layer 1 and the bottom 2 that are mutually bonded together, and surface layer 1 and bottom 2 are all strip, can be also other shapes.Orderly the arranging towards assigned direction of fiber of surface layer 1, in the present embodiment, the longitudinal arrangement that the fiber of surface layer 1 is orderly, i.e. the orientation of fiber is identical with the length direction of veil.It should be noted that, fiber orderly towards assigned direction arrange not require to form all fibres of surface layer 1 strict towards assigned direction, as long as its most of fiber is all towards assigned direction, and during visual detection, the fiber of surface layer is significantly arranged towards assigned direction, arranges lines clear.The unordered mixed and disorderly arrangement of fiber of bottom 2, surface layer 1 and bottom 2 are interweaved and are bonded together by the fiber on each layer.The smooth surface of the surface ratio bottom 2 of surface layer 1.
The utility model is to the not restriction of the concrete material of veil, its material can be also ES fiber and/or fluffy fiber, its fibrous material there is no different from the fibrous material that existing veil is used, just by change the arrangement mode of fiber in technique as methods such as combing operations, wherein, the bottom 2 of the unordered mixed and disorderly arrangement of fiber is the conventional material of this area, surface layer 1 is by change the arrangement mode of fiber in technique as methods such as combing operations, its be on the basis of conventional material change structure and, fiber alignment on it rule is visual visible.The physics and chemistry character of fiber is all the same with the fiber using in prior art, and the thickness of veil also can design according to actual needs in addition, more Bao Yuehao.
By reference to the accompanying drawings the utility model has been done to detailed explanation above; but embodiment of the present utility model is not limited in above-mentioned embodiment; those skilled in the art can make various distortion to the utility model according to prior art; as by the fiber direction of surface layer 1 by longitudinally changing to laterally etc., these all belong to protection domain of the present utility model.
Claims (3)
1. a two-layer nonwoven veil, comprise the surface layer and the bottom that are mutually bonded together, it is characterized in that, orderly the arranging towards assigned direction of fiber of described surface layer, the unordered mixed and disorderly arrangement of fiber of described bottom, the smooth surface of bottom described in the surface ratio of described surface layer.
2. two-layer nonwoven veil as claimed in claim 1, is characterized in that, described surface layer and described bottom are all strip, the fiber longitudinal arrangement of described surface layer.
3. two-layer nonwoven veil as claimed in claim 1 or 2, is characterized in that, described surface layer and described bottom are interweaved and are bonded together by the fiber on each layer.
