Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
As shown in FIG. 1, a water-washable, dirt-repellent wiping nonwoven fabric comprises a nonwoven fabric base fabric 1; the microporous dirt repellent layer 3 covers two sides of the non-woven fabric base cloth 1; a polytetrafluoroethylene membrane 2 is arranged between the microporous dirt-repellent layer 3 and the non-woven fabric base cloth 1.
Specifically, the microporous dirt repellent layer 3 is a polyurethane microporous film. Specifically, the flexible chain segments and the rigid chain segments inside the polyurethane molecules are alternately composed of: the flexible chain segment is a low molecular weight polyester chain segment without crystallinity and is easy to deform under the action of force; the rigid segment is a segment which has crystallinity and can generate transverse cross-linking, does not deform under the action of force, can prevent transverse slippage and enables the polyurethane to have enough resilience. When wiping is carried out, the rebound resilience of the microporous dirt-repellent layer 3 increases the wiping area, the wiping capacity is improved, and the good rebound resilience avoids the separation of the microporous dirt-repellent layer 3 and the polytetrafluoroethylene membrane 2.
Furthermore, the aperture of the micropores of the microporous dirt-repellent layer 2 is 0.2-10 μm, and the aperture of the micropores is small, so that the function of preliminarily blocking large dust can be achieved. Further, the arrangement of the micro-porous dirt-repellent layer 2 is completed by adopting a wet polyurethane coating process. The wet coating process is mature in technology and can be used for manufacturing the utility model as soon as possible.
Still further, the polytetrafluoroethylene membrane 2 is a garment membrane. The polytetrafluoroethylene clothing film is made by a biaxial stretching method, and each square centimeter of the surface of the film can reach more than billion micropores. Further, the aperture of the polytetrafluoroethylene membrane 2 is 0.02-15 μm, and the porosity is 85% -90%. The diameter of each micropore is hundreds of times smaller than that of a water molecule and is tens of thousands of times larger than that of a water vapor molecule, so that water vapor can pass through the micropore, and water drops cannot pass through the micropore, and the micropore structure can achieve excellent waterproof and moisture permeable functions and washing resistance. In addition, a polytetrafluoroethylene filmThe 2 is arranged between the micro-porous dirt-repellent layer 3 and the non-woven fabric base cloth 1, so that dust and other pollution can be further isolated, and the purpose of dirt repellency is achieved. Specifically, the polytetrafluoroethylene membrane 2 and the microporous dirt-repellent layer 3 are bonded through a hot melt adhesive. The gram weight of the hot melt adhesive is 10-15g/m2The PA hot melt adhesive net film facilitates the adhesion of the polytetrafluoroethylene film 2 and the microporous dirt-repellent layer 3, and the trace is not obvious. Furthermore, the non-woven base fabric 1 is made of the viscose cotton, the gram weight of the non-woven base fabric is 40-600, and the thickness of the non-woven base fabric is 0.5-3 cm.
The polytetrafluoroethylene membrane 2 for the clothes is compounded with the fabric of the non-woven fabric base cloth 1 by virtue of the waterproof and air permeability, so that the non-woven fabric base cloth 1 has the washing resistance similar to that of a textile. The diameter of the micropores is smaller than that of water molecules and larger than that of water vapor molecules, so that water vapor can pass through but water drops cannot pass through, and the micropore structure can achieve excellent waterproof, moisture permeable and water washing resistant functions. More preferably, the polytetrafluoroethylene film 2 is bonded with a polyurethane microporous dirt-repellent layer 3 by hot melt adhesive, and can bear most of the stress during wiping. And the resilience of the microporous dirt-repellent layer 3 can avoid the separation of the microporous dirt-repellent layer from the polytetrafluoroethylene membrane 2. The pore size of the microporous dirt-repellent layer 3 can block most of dust and other pollutants, and the purpose of primary dirt repellency can be achieved.
The utility model discloses a concrete operation does: the polytetrafluoroethylene membrane 2 and the non-woven fabric base cloth 1 are compounded, and then the polyurethane microporous dirt-repellent layer 3 is arranged on the polytetrafluoroethylene membrane 2 by a wet polyurethane coating process. The utility model discloses rational in infrastructure, easy operation.
Example two
As shown in fig. 2, unlike the above-mentioned embodiment, the non-woven fabric base fabric 1 has an antibacterial coating layer 11 having antibacterial properties on one side and a flame retardant coating layer 12 having flame retardant effect on the other side.
The utility model discloses a concrete operation does: the polytetrafluoroethylene membrane 2 is compounded with the non-woven fabric base cloth 1 fabric with the antibacterial coating 11 and the flame-retardant coating 12, and then the polyurethane microporous dirt-repellent layer 3 is arranged on the polytetrafluoroethylene membrane 2 by a wet polyurethane coating process. The utility model discloses rational in infrastructure, easy operation.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
