Abstract
The utility model relates to a kind of water-proof composite nonwoven fabrics, comprises stack connects successively nonwoven layer, reinforcement layer and watertight composition; The surface of described nonwoven layer is rectangle male and fomale(M&F) or circular male and fomale(M&F); Described reinforcement layer is the chemical fiber layer after sizing; Described watertight composition is to be made up of polystyrene resin film.The utility model, by watertight composition is set, makes nonwoven have water-proof function; By adopting reinforcement layer, not only effectively improve tension, resistance to compression, the tear strength of nonwoven, and under the prerequisite of guaranteeing product quality, reduced to greatest extent the requirement to nonwoven material, save material cost.
Description
Technical field
The utility model relates to nonwoven articles for use and makes field, particularly a kind of water-proof composite nonwoven fabrics.
Background technology
Nonwoven is a kind of fabric that does not need to spin cotton and weave cloth and form, and it is that textile staple or long filament are carried out to orientation or random support row, forms fibre net structure, then adopts the method reinforcing such as mechanical, hot sticky or chemical to form.
The base stock of nonwoven is mainly polypropylene, light because it is thin, good hand touch; Have porous, good permeability, easily keeps cloth cover dry and comfortable; Acid, alkali are had to excellent durability; And because polyacrylic chemical constitution is insecure, easily degraded, is also a kind of environmental friendliness shaped material, therefore, is widely used.But, in some particular application, except general performance, also require nonwoven to there is good fire retardant performance, and due to the raw material of nonwoven as polypropylene etc. be hydrocarbon class material, easily burning, current nonwoven only comprises the nonwoven surface layer of single or multiple lift.Structurally, net muscle is not all set.
Realizing in process of the present utility model, inventor finds that prior art at least exists following problem:
Do not have water-proof function, the scope of application is restricted;
The pull resistance of nonwoven, tear resistance, crushing resistance are all subject to the restriction of its material itself, cannot meet the demand of particular market.
Summary of the invention
In order to solve the problem of prior art, the utility model embodiment provides a kind of water-proof composite nonwoven fabrics.Described technical scheme is as follows:
The utility model embodiment provides a kind of water-proof composite nonwoven fabrics,
Described nonwoven comprises nonwoven layer, reinforcement layer and the watertight composition that stack connects successively;
The surface of described nonwoven layer is rectangle male and fomale(M&F) or circular male and fomale(M&F);
Described reinforcement layer is the chemical fiber layer after sizing;
Described watertight composition is to be made up of polystyrene resin film.
Particularly, described watertight composition fits in described reinforcement layer outer surface.
Particularly, described nonwoven layer is individual layer or more than individual layer.
Preferably, described nonwoven layer is polypropylene spun-bonded non-woven fabrics.
Particularly, described nonwoven layer and described reinforcement layer acupuncture combination, then bond with described watertight composition.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By watertight composition is set, make nonwoven there is water-proof function; By adopting reinforcement layer, not only effectively improve tension, resistance to compression, the tear strength of nonwoven, and under the prerequisite of guaranteeing product quality, reduced to greatest extent the requirement to nonwoven material, save material cost.
Brief description of the drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the water-proof composite nonwoven fabrics that provides of the utility model embodiment.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
The utility model embodiment provides a kind of water-proof composite nonwoven fabrics, and referring to Fig. 1, described water-proof composite nonwoven fabrics comprises nonwoven layer 1, reinforcement layer 2 and the watertight composition 3 that stack connects successively.
Particularly, nonwoven layer 1 is individual layer or more than individual layer.
Preferably, nonwoven layer 1 is polypropylene spun-bonded non-woven fabrics.
Further, the surface of nonwoven layer 1 is rectangle male and fomale(M&F) or circular male and fomale(M&F).
Preferably, reinforcement layer 2 is the chemical fiber layer after shaping.
Particularly, watertight composition 3 is to be made up of polystyrene resin film, fits in reinforcement layer 2 outer surface.
Wherein, between the nonwoven layer l on reinforcement layer 2, upper strata, adopt needling process, between the watertight composition 3 of bottom, reinforcement layer 2, adopt bonding process, not only make three layers to be mutually bonded together, also increased thickness and the globality of product.Its production process is by superimposed the nonwoven layer l on reinforcement layer 2, upper strata, then upper and lower while acupuncture, and roll, after rolling, is more evenly bonded in the watertight composition of bottom 3 on reinforcement layer 2, makes this water-proof composite nonwoven fabrics.Even by its interlayer fibre matting of the compound nonwoven cloth after acupuncture, intensity is consistent, and cortex sense is strong; Between the nonwoven layer l on reinforcement layer 2, upper strata, adopt needling process combination, between the watertight composition 3 of bottom, reinforcement layer 2, adopt bonding process combination.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By watertight composition is set, make nonwoven there is water-proof function; By adopting reinforcement layer, not only effectively improve tension, resistance to compression, the tear strength of nonwoven, and under the prerequisite of guaranteeing product quality, reduced to greatest extent the requirement to nonwoven material, save material cost.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
