Abstract
The utility model relates to a surface fabric and medical protective clothing of anti blood and alcohol infiltration, the surface fabric includes the base cloth, forms protective film on the base cloth, form and be in crosslinked membrane on the protective film, the part of crosslinked membrane is passed the protective film just inserts the base cloth. The utility model discloses the effect laminating of base cloth and protecting film through the crosslinked membrane is firm in the surface fabric to make the water of surface fabric to refuse the oily performance improvement, and then improved the ability of anti blood and alcohol infiltration, thereby make the virus propagation that the isolation patient body fluid splash that the protective clothing that the surface fabric made from this produced that can be better produced, reach higher safety protection rank.
Description
Technical Field
The utility model belongs to the technical field of medical protection product, concretely relates to surface fabric and medical protective clothing of anti blood and alcohol infiltration.
Background
Under the situation of a big outbreak of epidemic diseases, the safety protection problem of medical care personnel is particularly remarkable, the protective personnel can contact body fluid, blood, liquid medicine and the like of a patient at any time in the process of closely contacting the patient, the protective clothing needs to have extremely strong permeability resistance, the permeability resistance needs to be improved simultaneously when the permeability resistance is improved, the water resistance, oil resistance, blood resistance and alcohol resistance of the fabric needs to be improved, fluorine-based water and oil repellent finishing agents need to be used for finishing the fabric, a protective film is formed on the surface of the fabric, and the film needs to reach a very high water and oil repellent level. However, two technical problems exist at present, on one hand, the most commonly used non-woven fabric material is polypropylene, the glass transition temperature of the material is low, the water-repellent and oil-repellent finishing agent cannot be efficiently and orderly arranged through high-temperature baking to form a compact protective film, so that a good water-repellent and oil-repellent effect is achieved, in addition, the water-repellent and oil-repellent performance of C8 series in the general market is high, but the C8 waterproof agent contains PFOA and PFOS which have potential harm to human bodies, so that the industry standard of the European and American markets is limited, textiles with the PFOA and PFOS content exceeding 0.05% are forbidden to be sold, so the C6 fluorine-containing finishing agent is mostly adopted to carry out water-repellent and oil-repellent finishing on the textiles in the market, but the water-repellent and oil-repellent function of C6 series finishing is lower than that of C8 series finishing agents.
Disclosure of Invention
The utility model aims at providing a fastness that can improve protecting film and base cloth laminating to improve the surface fabric and the medical protective clothing of the anti blood and the alcohol permeability performance of surface fabric.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
an aspect of the utility model is to provide a surface fabric of anti blood and alcohol infiltration, the surface fabric includes the base cloth, forms protective film on the base cloth, forms crosslinked membrane on the protective film, the part of crosslinked membrane is passed the protective film just inserts the base cloth.
The utility model discloses a make the partial molecule branch of crosslinked membrane insert the protecting film like the root and form firm fixed point in inserting the base cloth, improved the fastness of protecting film with the base cloth laminating to improve the refuse oil repellency performance of surface fabric, and then improve the anti blood and the alcohol permeability of surface fabric.
Preferably, a plurality of fixing points formed by partially inserting the cross-linked film into the base cloth are distributed on the whole plane of the base cloth, so that the firmness of the fit between the protective film and the base cloth is further improved.
According to a particular and preferred embodiment, said base fabric is a non-woven fabric.
Further, the non-woven fabric is a polypropylene non-woven fabric.
Further, the non-woven fabric has an areal density of 40-60 g/m2。
According to a particular and preferred embodiment, the material of the protective film is a C6 three-proofing finish.
The utility model discloses an use polymer and fluorine-containing finishing agent that contain hydroxymethyl and/or epoxy simultaneously, fluorine-containing finishing agent at first forms the protective film that the water oil repellent is refused to the one deck on base cloth surface, and the polymer then forms the one deck crosslinked membrane again at the skin of protective film, and the protective film is inserted like the root to the partial molecular branch of crosslinked membrane, and inserts so that the protective film is firm with the base cloth laminating in the base cloth. Wherein the polymer containing methylol and/or epoxy groups may be modified chitosan or the like.
The utility model discloses the second aspect provides a medical protective clothing, medical protective clothing is made by above-mentioned surface fabric.
The utility model discloses a protective clothing adopts the surface fabric that has excellent anti blood and alcohol permeability to make for the virus that isolation patient's body fluid that protective clothing can be better spatters the production propagates, reaches higher safety protection rank.
Because of the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
the utility model discloses the effect laminating of base cloth and protecting film through the crosslinked membrane is firm in the surface fabric to make the water of surface fabric to refuse the oily performance improvement, and then improved the ability of anti blood and alcohol infiltration, thereby make the virus propagation that the isolation patient body fluid splash that the protective clothing that the surface fabric made from this produced that can be better produced, reach higher safety protection rank.
Drawings
FIG. 1 is a schematic structural diagram of a fabric according to a specific embodiment;
in the above drawings: 1. a base cloth; 2. a protective film; 3. a crosslinked film; 31. a portion of the membrane is crosslinked.
Detailed Description
The invention will be further described with reference to examples of embodiments shown in the drawings.
The fabric shown in figure 1 comprises a base cloth 1, a protective film 2 formed on the base cloth 1 and a cross-linked film 3 formed on the protective film 2, wherein a part 31 of the cross-linked film 3 penetrates through the protective film 2 and is inserted into the base cloth 1, and a plurality of fixing points formed by inserting the part 31 of the cross-linked film 3 into the base cloth 1 are distributed on the whole plane of the base cloth 1, so that the firmness of the attachment of the protective film 2 and the base cloth 1 is further improved.
