Abstract
Disclosed is a water-repellent non-woven fabric with a hydrophobic region. A hydrophobic region 2 is arranged on a water-repellent surface 1 of the water-repellent non-woven fabric. The hydrophobic region 2 can be strip-shaped, round-shaped or non-round-closing-shaped. The utility model has the characteristics of both the hydrophobic non-woven fabric and the water-repellent non-woven fabric, so that the water gathered on one side of the water-repellent non-woven fabric can be guided to the hydrophobic region to gather up and flow directionally to the other side. The water-repellent non-woven fabric can be used as the point-oriented gathering or filtering appliance for the water just like a hopper, or as the agricultural-trickle-irrigation or leakage-use fabric, or as the permeable packaging material, in particular as the sanitary fabrics including anti-side-leakage women-use sanitary towel fabric, baby-use diaper fabric and paper diaper fabric. The utility model expands the non-woven fabric application area and is lower in cost, so that the processing technique of the finished product can be greatly reduced and the production cost can also be reduced.
Description
Technical field
The utility model relates to a kind of nonwoven fabric, relates in particular to a kind ofly to refuse the water nonwoven fabric with hydrophobic region.
Background technology
Because better performances such as nonwoven fabric stretch-proof distortion, anti-fracture strength and percentage elongation and production cost are low, so be widely used in fields such as medical protection, clothes, industrial cloth, building, agriculturals, particularly at personal hygiene article such as sanltary towel, baby diaper, the large usage quantity of nonwoven fabric in the articles for use such as urine trousers.Nonwoven is furnished with hydrophobic type and refuses two kinds on water type, refuse water type nonwoven fabric and can intercept passing through of water, so can be used as the base fabric of sanitary napkin or diaper uses, the surface layer of sanitary napkin adopts material making such as hydrophobic type nonwoven fabric usually, sometimes for preventing side leakage, dual-side at the sanitary napkin surface layer also needs to have the performance of refusing water, this just requires on the sanitary napkin surface layer hydrophobic region to be arranged, also the zone of refusing water to be arranged, make combination if adopt two kinds of materials, often cause the ride comfort of its surface layer poor, and complex manufacturing technology.
Summary of the invention
The purpose of this utility model is to refuse that water type nonwoven fabric can only whole block water and can not the local permeable inconvenience that brings at existing, proposes a kind ofly to refuse the water nonwoven fabric with hydrophobic region.
The purpose of this utility model realizes in the following manner: the band hydrophobic region refuse the water nonwoven fabric, the water surface of refusing of refusing the water nonwoven fabric is provided with hydrophobic region.
Hydrophobic region described in the utility model is bar shaped, and it is parallel or perpendicular to the length direction of refusing the water nonwoven fabric.
Hydrophobic region described in the utility model is circular or non-circular close-shaped.
Hydrophobic region five equilibrium described in the utility model is distributed on to be refused on the water nonwoven fabric.
Compared with prior art, the utlity model has following tangible advantage:
1. hydrophobic region is set refusing the water nonwoven fabric, is equivalent on its lining, be provided with specific water-in and water-out passage.Applicable to the occasion that requires to specify aquaporin, be particularly suitable for as anti-side leakage sanltary towel, baby's diaper the lining of health such as urine trousers.
2. the utility model has the hydrophobic nonwoven and the characteristics of refusing the water nonwoven fabric concurrently, can guide to hydrophobic region and concentrates oriented flow to opposite side refusing water that water nonwoven fabric one side compiles.Can compile as the fixed point of water or filter articles for use as funnel, or as agricultural drop irrigation or infiltrating irrigation cloth, or as the packing timber of gas permeability, make and refuse the water nonwoven fabric and had new function, expand the field that nonwoven fabric is used.
3. the utility model cost of manufacture is lower, and is easy to use, can significantly simplify the processing technology of its manufactured goods, reduces its production cost.
Description of drawings

Fig. 2 is the vertical view of Fig. 1
Fig. 3 is the schematic diagram of the another kind of structure of the utility model
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Referring to Fig. 1, Fig. 2, first kind of structure of the present utility model designs at the used nonwoven fabric lining of amenities such as sanitary napkin or diaper, diaper, urine trousers, the band hydrophobic region refuse the water nonwoven fabric, the water surface 1 of refusing of nonwoven fabric is provided with hydrophobic region 2.Hydrophobic region 2 can adopt intensive syringe needle to form in the mode of refusing the specific region punching on the water surface 1, also can adopt to spray or modes such as immersion make material adhesion multifunctional assistant in the hydrophobic region 2, makes its possess hydrophilic property energy.Refuse the water nonwoven fabric for what paste on hydrophilic nonwoven fabrics that the curtain coating face constitutes, also can adopt as the mode of hot melt etc. and remove casting films in its setting regions, thereby constitute hydrophobic region 2.Hydrophobic region 2 is bar shaped, and the length direction of its parallel nonwoven fabric determine the bar number of its width and layout by sanitary napkin or the required size of diaper materials, and five equilibrium is distributed on the lining.This hydrophobic region 2 also can be provided with perpendicular to the length direction of nonwoven fabric.When the surface material as side leakage preventing sanitary towel or diaper uses, can directly cut out blanking by the position of hydrophobic region 2.Reduced the technology of in the side leakage preventing sanitary towel surface layer manufacturing process water wetted material being refused water treatment.The sanitary napkin surface layer is more smooth-going, makes more convenient and production cost decline.
Referring to Fig. 3, first kind of structure of the present utility model designs at air-permeable packaging material,, also can make as square ellipse, polygon or other is non-circular close-shaped refusing hydrophobic region 2 on the water nonwoven fabric for circular close-shaped.The quantity of its circular hydrophobic region 2 is the amount doesn't matter.Hydrophobic region 2 five equilibriums are distributed on refusing on the water surface 1 of nonwoven fabric in Fig. 1 and Fig. 3.Also other arrangement.All the other all with embodiment 1 roughly the same, this paper does not give unnecessary details.
The utility model can also compile or filters articles for use as the fixed point of water, and as agricultural drop irrigation or infiltrating irrigation cloth, as packing timber or other purposes of gas permeability, cost of manufacture is lower, and is extremely easy to use.
