[Prior art and problems to be solved by the invention]

Flame-retardant fabric foils are used in domestic applications such as upholstery, curtains, pine upholstery, and nightstands, as well as in research institutions, hospitals, or other commercial facilities where the safety elements associated with such fabric foils are desired. Desirable for manufacturing. In some countries, the use of flame retardant bedding fabrics in facilities such as hospitals, nursing homes, psychiatric institutes, prisons, universities, etc. is required by law.

Flame retardancy has been achieved in cotton-heavy fabrics, such as A, C, A, striped tomato tresscover fabrics, by treating the cotton-heavy fabrics with hydrated sodium borate compounds. This sodium borate treatment is
In addition to reducing the speed of flame travel through the fabric foil, removing the external flame source also imparts self-extinguishing properties to the fabric such that the treated fabric foil itself cannot substantially support the flame. It serves the function of a second person, which is to attach a person.

In addition to being flame retardant, in many applications it is desirable for the fabric foil to be bacteriostatic and/or removable and water resistant. Treated fabric foils that combine these properties are highly suitable for use in the production of pine tress coverings for use in institutions such as hospitals and prisons. of course,
Fabric foils used as institutional pine tress coverings must also be highly resistant to the abrasions associated with institutional use. The A, C, A striped cover fabric described above has acceptable abrasion resistance. However, the chemical resistance of this fabric is poor and therefore its flame retardant properties decrease as a result of exposure to common cleaning.

The cloth foil disclosed therein is a flexible sheet of polyvinyl chloride containing about 0.10 to 0.60% bis(tri-n-alkyltin) sulfosaline sylate fungicidal compound coated or laminated on both sides with nylon. Consists of scrim. However, because of the relatively large amount of polyvinyl chloride present in the polymeric vinyl layer of this product, when exposed to direct flame, the vinyl layer chars and releases a relatively large amount of toxic fumes.

Fiberglass fabric and wool have been used in the manufacture of waterproof pine tress pads.

The prior art discloses coated fabric foils that are flame retardant, bacteriostatic, bacteriostatic, impermeable to liquids such as water and urine, resistant to chemical attack, and It does not provide chemically coated fiberglass fabric foils that do not release dangerous amounts of toxic fumes upon combustion.

Accordingly, one object of the present invention is to provide a coated fiberglass fabric having each of the above-mentioned properties.

It is also a further object of the invention to provide applications for commercial use in hotels, in institutions such as hospitals and prisons, and in other settings where extreme conditions of use prevail. The object of the present invention is to provide a fiberglass-based pine tress covering that is particularly suitable for use on pine mats used in the industry.

[Means for solving the problem, action and effects of the invention]

According to the invention, in accordance with the above object, it is composed of a woven or non-woven fabric of glass fibers, a first coating layer of a coating composition based on a polymer, and a second surface coating layer on the first coating layer; The coating composition comprises a polymer selected from the group consisting of polyvinyl chloride, polytetrafluoroethylene, neoprene, vinyl chloride vinyl acetate copolymer, ethylene vinylidene chloride copolymer, chlorosulfonated polyether, acrylic homopolymer or copolymer, and silicone rubber. wherein the polymeric carrier contains an effective amount of a flame retardant and an effective amount of a disinfectant and a bactericidal agent, and the amount of the coating composition constituting the first coating layer is such that the glass fiber cloth is said second coating layer contains an effective amount of a disinfectant and a disinfectant in an amount suitable to render the coating substantially impermeable to liquids and resistant to bacteria and fungi.

A developing, non-abrasive and chemically resistant pine tress covering is provided.

The present invention also comprises a woven or non-woven fabric of glass fibers and a coating layer of a coating composition based on a polymer, said coating composition comprising a plasticizer, an effective amount of a flame retardant, and an effective amount of a flame retardant. and a bactericidal agent, and the amount of the coating composition constituting the coating layer is to render the glass fiber cloth impermeable to liquids and resistant to bacteria and fungi. upholstery, drapery, pine tress upholstery, characterized by matching quantities;
A coated fabric foil suitable for use in the manufacture of pine tress covers, pine tress covering fabrics, etc.
provided.

The chemically coated fabric foil of the present invention consists of a woven or nonwoven base of glass fibers to which one or more thin layers of a polymeric coating have been applied. The base of the glass fiber cloth foil is
It is inherently flame retardant. Additionally, the coating is flame retardant and renders the base of the glass fiber cloth impermeable to liquids such as urine, and bacteriostatic and/or bacteriostatic. Also, the coating layer is chemically resistant, so the coating does not deteriorate when exposed to normal cleaning.

The base of the fabric foil can be comprised of any conventional glass fiber woven or non-woven fabric. However, the particular fiberglass fabric selected will depend on the intended end use for the coated fiberglass fabric product. For example, for manufacturing the pine tress cover fabric of the present invention,
A fiberglass cloth foil having a tensile strength in the range of about 150 psi to about 292 psi (about 10.5-20.5 Kg/cm ² ) is used. Preferably, the glass fiber woven or non-woven fabric used to make the pine tress covering fabric of the present invention has a tensile strength of about 250 psi (17.6 Kg/cm ² ).
Fiberglass fabric foils having tensile strengths in the indicated ranges exhibit a degree of resiliency and tear resistance that is considered desirable for commercial pine tress coverings.

A particularly suitable glass fiber cloth foil for use in the manufacture of pine tress coverings is a glass fiber cloth woven in a jacquard weave. Jacquard weaving has been found to increase the strength of fiberglass fabrics. The glass fiber yarn capable of jacquard weaving is a single-ply C-fiber yarn that is one turn out-of-twist and has a denier value of 75. During weaving, one 42 inch (107 cm) warp thread is wrapped around four beans of 2 x 523 and 2 x 524 and a 12-harness weave is used to form the jiyaqat pattern. . The cloth is approx.
Weight of 8.71 oz/yd (270g/m) and approx.
It has yards/pounds (3.14m/Kg). This type of fiberglass cloth has style designation number 487/242/

The coating layer applied to the fabric foil base consists of a polymeric carrier containing one or more components that contribute to the flame retardant properties of the coating, such as antimony pentoxide and/or antimony trioxide. The coating formulation also contains effective amounts of plasticizers, and fillers,
and one or more types of bacteriostatic and/or bacteriostatic agents. Preferably, the filler functions as a flame retardant.

Examples of suitable polymeric carriers are chlorine-containing polymers such as polyvinyl chloride, vinyl chloride vinyl acetate copolymers, acrylic vinyl chloride latex or ethylene vinylidene chloride copolymers. A suitable ethylene vinylidene chloride copolymer carrier is available from Air Products Corp. under the trade name Air Flex 45-14.
Commercially available from. Alternatively, the polymeric carrier may be polychloroprene (i.e., neoprene); a chlorosulfonated polyether, e.g.
Dow Chemical Company
Hypalon, or silicone rubber, commercially available from Co., Ltd.). The polymeric carrier can also consist of vinyl chloride acrylic copolymers, or acrylic homopolymers or copolymers, or polytetrafluoroethylene. However, preferred polymeric carriers are
An acrylic vinyl chloride latex composed of a carboxylated copolymer of vinyl chloride and a soft acrylic that crosslinks itself upon curing. This type of polymer is manufactured by BF Gudryutsch Company (BF
Goodrich Co. of Akron, Ohio).

Common plasticizers that are compatible with the other components of the coating formulation can be used. For example, examples of suitable plasticizers are phosphate plasticizers such as paratricresyl phosphate or octyl diphenyl phosphate. Paratricresyl phosphate is a colorless liquid, and in addition to functioning as a plasticizer, it also contributes to the water resistance and flame retardancy of the coating.

Plasticizers can also consist of chlorinated or brominated paraffin compounds which, in addition to improving the "feel" of the coating, function to promote flame retardancy of the polymeric carrier. . Preferred plasticizers of this type are chlorinated paraffins with a chlorine content of about 50%.

The coating formulation can include components such as aluminum trihydrate that contribute to the flame retardancy of the coating. When exposed to heat, aluminum trihydrate releases water vapor and therefore functions as a flame retardant.

The main flame retardant ingredients used in the coating are antimony trioxide and/or antimony pentoxide. These compounds, when used in combination with chlorine- or bromine-containing compounds in the coating formulation, in the proportions described, impart flame retardancy to the coating.

Antimicrobial and/or antifungal properties of the coating are provided by the inclusion of bacteriostatic and/or bacteriostatic agents in the coating formulation. Any conventional disinfectant and/or fungicide compatible with the polymeric carrier and other ingredients of this formulation, such as bis(tri-n-alkyltin) sulfosalicylate as disclosed in U.S. Pat. No. 3,279,986. can be used. However, a preferred disinfectant and disinfectant is N-trichloromethylthio-4-cyclohexene-1,2-dicarboximide. The bactericidal and deodorizing properties of N-trichloromethylthio-4-cyclohexene-1,2-dicarboximide also have the ability to prevent coating stiffening caused by plasticizer depletion caused by bacterial and fungal activity. I can do it. This compound has the trade name

In order to function effectively as a disinfectant, in particular to prevent unsightly mildew and bacterial growth, the disinfectant and/or bactericidal component must migrate to the surface of the coating layer. The rate of migration of the sterilizing and/or bactericidal component is determined by its compatibility in the coating formulation. If this component does not move at the appropriate speed, no effective concentration of active component will be present at the surface of the coating layer. On the other hand, if the disinfectant and/or disinfectant moves too quickly, unsightly blooming of that component of the coating layer will occur. According to the coating formulation of the present invention, about 0.5 to 2 parts, preferably about 1 part of the disinfectant and fungicide) polymeric carrier.
(based on 100 parts) using, for example, N-trichloromethylthio-4-cyclohexene-1,2-dicarboximide. At this concentration level, the disinfectant and disinfectant are compatible with the other ingredients of the formulation and provide a concentration of ingredients on the surface of the coating that is effective against fungi and bacteria.

Preferably, the coating formulation comprises a polymeric carrier.
Based on 100 parts, about 25 to 75 parts of filler (e.g., aluminum trihydrate), about 5 to 25 parts of plasticizer, about 3 to 10 parts of antimony trioxide or antimony pentoxide, and about 0.5 parts. Contains ~2 parts of disinfectant and/or disinfectant. Preferably, the polymeric carrier is an acrylic vinyl chloride latex, the filler is aluminum trihydrate, and the plasticizer is a chlorinated paraffin with a chlorine content of about 50%;
The fungicide and disinfectant is N-trichloromethylthio-4-cyclohexene-1,2-dicarboximide. For example, the coating formulation is
Based on dry weight, about 140 parts acrylic vinyl chloride latex, about 56 parts aluminum trihydrate, about 6 parts antimony pentoxide, about 30 parts chlorinated paraffin (50% chlorine) and about 1 , 7th part N
-Trichloromethylthio-4-cyclohexene-
It can consist of 1,2-dicarboximide.

The coating formulation is prepared by first mixing together the polymeric carrier, antimony pentoxide, and aluminum trihydrate in the form of an approximately 50% dispersion of each component in water. Although aqueous solvent systems are preferred because they do not pose the environmental hazards associated with more volatile solvent systems, other compatible solvent systems can be used. Additionally, polyvinyl chloride or vinyl chloride vinyl acetate plastisols can be used.

Preferably, prior to dispersion in water, the aluminum trihydrate is ground in a mill to reduce the average particle size of the aluminum trihydrate to less than about 10 microns. Aluminum trihydrate is then added in water to about 1
% by weight (based on the dry weight of aluminum trihydrate) in the presence of the dispersion. Examples of suitable dispersants are nonionic dispersants, or trisodium phosphate or other compatible dispersants.

A plasticizer and a bactericide and/or a disinfectant are then added to the aqueous dispersion of polymeric carrier, flame retardant and aluminum trihydrate. Before coating the formulation onto the textile base, the viscosity of the formulation is adjusted by addition of suitable thickeners. The viscosity of the formulation to be adjusted is determined by the particular coating method used. Examples of suitable thickeners are methylcellulose,
High molecular weight acrylic acid or preferably non-ionic thickeners such as union carbide.

It is.

After adjusting the viscosity of the formulation, adjust the pH of the formulation to approximately
Adjust with acid or base as necessary to less than 7.0, preferably within the range of about 5.5 to 6.5. Preferably
The acid used to adjust the pH is acetic acid and the preferred base is ammonia.

The coating formulation can be applied onto the fabric foil base using conventional coating techniques. For example, the floating knife method,
A roll knife method or a reverse roll coating method can be used. For use in the floating knife coating method, the viscosity of the formulation should be adjusted to about 4000 to 16000 centipoise, preferably about 16000 centipoise, preferably by the addition of thickeners. When using the roll knife coating method, the viscosity of the formulation is preferably adjusted to about 50,000 to 60,000 centipoise. For use in reverse roll coating methods, the viscosity of the formulation is preferably adjusted to about 4000 to about 5000 centipoise. The preferred coating method for applying the coating formulation to the glass fiber cloth base is the floating knife method, in which the viscosity of the coating composition is approximately
With the addition of 1.6 parts of thickener (on a dry weight basis) approx.
Adjust to 16000 centipoise.

When applied to a cloth foil base, the coating is cured by passing the coated cloth foil through an oven at a temperature of about 325°C (163°C).

The coating can be applied to one or both sides of the fiberglass cloth foil base. The weight of the applied coating is
There should be no more than about 6 ounces (170 g) per square yard (0.84 m ² ) of fabric, and no less than about 1 ounce (28.4 g) per square yard (0.84 m 2 ). Preferably, the applied weight of the covering layer is from about 2 ounces (56.7 g) to about 3 ounces per square yard (0.84 m ² ) of fabric base.
oz (85.1g).

The coating layer adheres well to the fiberglass cloth foil base and requires no auxiliary adhesion promoters. However, adhesion promoters can be included in the coating composition, the use of which may be desirable, especially when using adhesion resistant fiberglass foils. An example of a useful adhesion promoter is N-(β-aminoethyl-γ-aminopropyl)-trimethoxysilane. This type of adhesion promoter is
Commercially available from Union Carbide Corp. as A1120.

When the polymeric carrier of the coating composition is a latex-type carrier, such as the acrylic vinyl chloride latex described above, the surface texture of the cured fabric coating may be tacky. The surface of the cured fabric coating is finished by applying an additional coating layer of polymeric material to the cured coating layer. The outer coating layer provides a smooth, abrasion resistant surface to the fabric surface. For example, a thin finish layer of vinyl chloride acrylic compound can be applied to the fabric by any of the coating methods described above. An effective amount of disinfectant and/or disinfectant is included in the composition used as the surface coating layer to ensure that an effective amount of disinfectant and/or disinfectant is present on the surface of the fabric coating. You can also do that. For example, about 1 part by weight of N-trichloromethylthio-4-cyclohexene-1,2-dicarboximide can be included in the formulation used as a surface coating layer.

The surface coating layer preferably contains about 0.1 to about 0.5 ounces per square yard (0.84 m ² ) of fabric.
