Abstract
The utility model relates to a polyurethane environment purification fabric with a porous structure. The polyurethane environment purification fabric comprises a fabric layer and a coating layer on the surface of the fabric, a polyurethane layer is composited on the surface of the fabric, the surface of the polyurethane layer is provided with a punctuate projecting structure, and the network structure of polyurethane is directly connected into the gap between a horizontal fiber and a vertical fiber of the fabric. The fabric is simple in structure, only one coating layer is composited on the surface of the fabric, environments can be purified owing to adsorption of the coating layer, and the fabric is a simple and effective environment cleaning product.
Description
Technical field
The utility model relates to field of textiles, is specifically related to a kind of fabric with environmental purification function.
Background technology
Multiaspect oligomeric silsesquioxanes (POSS) is a kind of compound of nanostructured; Comprise inorganic and organic 2 parts; Silicon and oxygen constitute the inorganic structure center, and this structure centre is covered by organic substituent, so POSS and derivative thereof have been gathered organic and inorganic many characteristics.Each POSS particle all contains one or more organic active functional group, and these functional groups can carry out polymerization, grafting, surface bond or other reactions, forms the POSS-polymeric material.
At present, market increases the demand of clothes hygienic finishing.In public places with life in, people meet with inevitably the greasy smell that comes out in the tail gas, kitchen of cigarette flavor, automobile, lavatory peculiar smell, stink that sweat causes, to add age smelly etc.And textiles has the ability that from surrounding air, absorbs these smells significantly, becomes the adsorbent of volatile materials.Therefore, when fabric passes through desorption, will make troubles to the people when discharging the smell that makes us unhappy.Existing textiles is carried out deodorizing or mostly purified treatment is the subsidiary effect through its antibacterial functions, its deodorization or clean-up effect are not satisfactory.
The utility model content
The technical problem that the utility model will solve is that a kind of fabric with environmental purification function is provided.
The technical scheme of the utility model is, a kind of polyurethane environment of loose structure purifies fabric, comprises tissue layer and coating surfaces, and the face of said tissue layer is compounded with layer of polyurethane, the raised structures that said layer of polyurethane surface has point-like; The network-like structure of said polyurethane directly is connected in the transverse and longitudinal fibre gap of fabric.
Polyurethane environment according to the loose structure of the utility model purifies fabric, preferably, is embedded with the small porous particle structure in the network-like structure of said polyurethane.
Further, also be embedded with compound of polysaccharide in the network-like structure of said polyurethane.Described compound of polysaccharide is selected from starch, Arabic gum, pectin, cellulose, hemicellulose, hyaluronic acid, shitosan, cyclodextrin a kind of or more than one.Said cyclodextrin preferred alpha-cyclodextrin, beta-schardinger dextrin-and gamma-cyclodextrin.
In a preferred embodiment, the raised structures of said point-like is spherical in shape or square.
Polyurethane environment according to the loose structure of the utility model purifies fabric, and preferably, the thickness of said layer of polyurethane is 10-100 μ m.
In a preferred embodiment, the density of said layer of polyurethane is 0.1-5g/cm
3..
The fabric of the utility model has adopted the method for compound PU coating, can form porous film on the inside and outside surface of fiber.And in the network structure of PU, be embedded with POSS or compound of polysaccharide.POSS is the polyhedron oligomeric silsesquioxanes, is that the hydrolysis through organosiloxane prepares.Exist two kinds of apertures in the formed mesoporous material of POSS in fact, i.e. hole in the POSS cube and the space between cube utilize the cooperative effect of formed loose structure of POSS and saccharide compound hydrophobic cavity, fabric are played the effect that purifies air.
Cyclodextrin is starch hydrolysis and the cyclic oligosaccharide (cyclodextrin) that produces has natural sex and mildness under the effect of enzyme, and is biodegradable, satisfies environmental requirement.Cyclodextrin has void structure, can accept " posting body " molecule as " place body ".The stink control effect is based on physics seizure effect: promptly volatile materials is produced " place body-post body " complex effect, thereby cause postponing desorb or release, reach the purpose of deodorization deodorizing.The inside, hole of cyclodextrin is hydrophobic, and most of smell substances also are hydrophobic, is caught by cyclodextrin easily and makes textiles keep pure and fresh, reaches the purpose that its ambient air purifies.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1-layer of polyurethane, 2-tissue layer, the raised structures of 3-point-like.
The specific embodiment
Describe in further detail below in conjunction with the specific embodiment of accompanying drawing the utility model.
Like Fig. 1, the polyurethane environment of the loose structure of the utility model purifies fabric and comprises layer of polyurethane 1 and tissue layer 2, and the one side of tissue layer 2 is compounded with layer of polyurethane 1, and layer of polyurethane 1 surface has the raised structures 3 of point-like; The network-like structure of said polyurethane directly is connected in the transverse and longitudinal fibre gap of fabric.
In another embodiment, be embedded with the POSS group in the network-like structure of said polyurethane.
In another embodiment, also be embedded with compound of polysaccharide in the network-like structure of said polyurethane.Also can in the network-like structure of polyurethane, be embedded with POSS group and compound of polysaccharide simultaneously.Hole in the POSS cube and the space between cube utilize the cooperative effect of formed loose structure of POSS and saccharide compound hydrophobic cavity, fabric are played the effect that purifies air.
In one embodiment, the raised structures 3 of above-mentioned point-like is spherical in shape or square.
The thickness of layer of polyurethane is 10 μ m.
The weight of said layer of polyurethane is 70g/m
2.
In all the other embodiments, can be at the weight 60-120g/m of the thickness 10-100 of layer of polyurethane μ m and layer of polyurethane
2Select other numerical value in the scope.
The fabric construction of the utility model is simple, only gets final product in the compound coating of fabric face, but because the suction-operated of coating can be played catharsis to environment, is a kind of simple, effective environmental cleaning products.
