These paintings and their products have the ability to decompose within a relatively short period of time. 5 C. and 12 C.p. f-crystals, 1 tab., 8 Il.

The invention relates to heat-sealable biodegradable fabrics, designed for packaging and disposable products, such as sanitary napkins, tampons, diapers, surgical dressings, dressings for wounds, and for other applications in which a component of the product is permeable or impermeable plastic film and in which preferably the film is able to decompose biologically or at least reduced, when the product is thrown away after use. In particular, the present invention from the periods of time, comparable to the transition process or processing waste treatment technologies commonly used for end products and packages, including such films.

Heat-sealable plastic film or fabric are widely used as packaging for products outer wrapper for packaging and as components products. For example, the permeable and impermeable components of disposable products such as diapers, sanitary napkins, products for those who suffer from incontinence, surgical gowns and hospital bedding, are mainly to be made entirely or partially of heat-sealable films or paintings.

From U.S. patent 4020228 (CL 09 J 7/02, publ. 26.04.77) known heat-sealable biodegradable fabric, including the basis of decaying flexible sheet material and thermoplastic coating placed on the basis for the ability of foundations to thermoclean.

From the publication of the international application WO 93/00116 (class a 61 L 15/00, publ. 07.01.93) known absorbent article containing the absorbent inner layer and a layer basis, in which the layer of the framework consists of a heat-sealable biodegradable films containing the basis of Ionova, to ensure the ability of the framework to thermoclean.

From the same publication, the known absorbent article containing top layer and bottom layer, between which is absorbent inner layer that includes a heat-sealable biodegradable film containing the basis of the heat-sealable biodegradable flexible sheet material and thermoplastic coating placed on the canvas, for the ability of foundations to thermoclean.

From the United Kingdom patent GB 2272916 (class a 61 L 13/15, publ. 01.06.94) known tampon containing the inner layer of absorbent material and permeable coating layer is located around the inner layer, surrounding it.

From the United Kingdom patent GB 1108291 (class a 61 F 13/20, publ. 03.04.68) known applicator for a tampon containing an outer tube, in which the tampon thread to pull the tampon and the inner tube, with the inner and outer tubes are made of cellulose material of the group consisting of paper, cardboard, plastic or composite material, in which the inner layer is cardboard and the outer layer is a thermoplastic coating.

However, the known films, including heat-sealable p is Biologicheskie degradable or degradable by other mechanisms within the time, comparable to the duration of the transient processes that have product removal systems of sewage sludge and industrial waste composting. For example, although future developments in this area and will reduce these ranges, the system anaerobic wastewater treatment are exposed to loads of waste, including materials and products, and process them within a time period of approximately 30 days; aerobic wastewater treatment systems are exposed to loads of waste within 7-10 days; in modern industrial systems, composting wastes are transitional processes in length from a few to 24 weeks. The time when burying waste in the ground is measured in decades and centuries, although measures for disposal and their possible correction can reduce the time waste and recycling.

Except for certain types of coated paper, among the commonly used packaging materials, only the cellophane without coating degrades over time transients, which typically exposed to sewage sludge. However, cellophane, being neuroplasticity, not vitasti, torsion or the application of cold glue, hot melt glue or glue, effective under pressure in those applications that require bonding. If such adhesives or other coatings to be applied to the entire surface of the cellophane (to ensure uniform bonding or modification of properties such as sensitivity to moisture in the water vapor permeability), it would be harmful to affect the ability of the plastic to biodegradable during wastewater treatment and composting, and the time required for decomposition of the waste disposal in the ground, will be unpredictable to increase. Similar observations can be made in reducing the rate of biological decomposition, gidralizovanny, fragmentation and the ability to wash any thermoplastic film coated or neuroplasticity decaying film, for example, polycaprolactone, preparationsand, polylactide, polyhydroxybutyrate, polyhydroxyvalerate, their copolymers, modified starches, etc., When such films are coated, accessed degrading agents, such as microorganisms, enzymes, water, or other solvent medium, is blocked, or at least essentially obstructed.

These technical problems are solved due to the fact that heat-sealable biodegradable canvas, including the basis of decaying flexible sheet material and thermoplastic coating placed on the canvas, for the ability of foundations to thermoclean according to the invention the coating is discontinuous, which is available for decomposing agents and decomposes through the mechanism from the group consisting of biodegradation and gidrolizuet.

Fig. 8 is a perspective view of conventional products, applicator pad, apply a heat-sealable by heating the sheet for formation of a smooth outer surface.

Now carefully examine the drawings, in which similar elements have the same designation in Fig.1 and 2 the film in the form of a cloth marked in position 10. The film 10 includes a base 12 and a coating 14 of a thermoplastic adhesive, on her broken figure.

The base 12 may take the form of a film or, as will be explained further, non-woven material. The basis of 12 RA Instances of films, demonstrate the ability to decomposition and can be used as the base 12 in accordance with the present invention, include cellophane, cellulose acetate, cellulose nitrate, collagen, chitin, chitosan, polycaprolactone, polylactide, polylactic acid, polyglycolide, preparationsand, polyhydroxybutyrate, polyoxometalate, copolymers of polyoxometalate and polyoxometalate, polyvinyl alcohol, polyvinyl acetate, nylon 2,6, polyvinylpyrrolidone, carboximetilzellulozu, hydroxyethyl cellulose, polyethylene glycol, methoxypolyethyleneglycol, oxides and carboximetilzellulozu, oxyalkylation, for example, acetylsalicylate, oxypropylation and oxypropylation, methylcellulose, plasticized starch and polymer films with a high dosage of starch and/or plasticizer, where the starch content above 50% by weight. Specialists in the art will know that other appropriate materials.

Examples of additives that can be included in the material, forming a film used as the base 12, are substances that prevent adhesion, to reduce unwanted samozlepny and unwanted lipincott, antioxidants and other stabilizers to control degradation prior to and during application, additives reduce friction, antistatic agents, fillers and pigments.

Also suitable materials for use as the base 12 are biodegradable non-woven materials made, for example, cotton/synthetic fibers or blends of cotton of artificial fibres, of different fabrics and paper or other biodegradable fibers and mixtures of fibers, such as wood fiber, flax, jute, ramps, chitin and chitosan. Such non-woven materials, when they are connected from lap with combed fibres or with a random arrangement of fibres ways without using a binder, for example, by hydropyridine, they are not able to stick together when heated. Therefore, they benefit from the use of discontinuous thermoplastic coatings in accordance with the present invention.

In the currently preferred as films and nonwoven materials for the base 12 are the foundations that before decomposition are sufficiently strong and durable to serve their intended purposes, they are readily available and can easily cause Ter is assumed within the time of transient processes in conventional and proposed waste management for the product, element of which it should be. For these reasons, the examples of preferred bases are cellophane and specific tissue based on wood fibers and paper. However, the most preferred is cellophane, thanks to its great usefulness and ubiquity as a barrier packaging material, its flexibility and good strength and high performance release film. Will also be preferred other films that may be readily available and which meet the requirements for the ability to decompose, certain traditional ways of processing products, in which they must be included.

The coating 14 can contain regular and recurring figures of random geometric shapes, abstract shapes, natural forms, etc. Shapes can be connected or disconnected, because it is made by a significant number of gaps in the figure to open the decaying foundations without coating. The coating 14 must be thermoplastic as it passes through a sticky phase during heating allowing it to stick to itself, to decompose the base 12 or to another material or element to which it is desirable to attach the base of abny to provide the desired intermittent coating 14 to 12. The preferred methods of coating 14, which will be described further, are basically ways of printing, for example, gravure printing and screen printing. You can also apply unaccented ways, for example, the fountain and laser ink jet printing.

Many of the cover 14, is suitable for the present invention is applied in the form of a suspension or solution in a volatile liquid, which is then removed, dried or utverjdayut on the spot. Most of these compositions consist of three components: a binder which is a polymer material that forms the coating; the pigment, when it is required, opacity or color; and a volatile carrier liquid, which is removed after coating. Examples of appropriate binders are polyvinyl alcohol, grades, polyvinyl chloride, polivinilhlorid, polyvinyl acetate, polyacrylates, polyalkylacrylate (for example, polymethylmethacrylate), nitrocellulose, ethylcellulose, cellulose-acetotrophic, cellulose-acetylbutyrate, methylcellulose, oxypropylation, ethoxyethylacetate, copolymers of ethylene and acrylic acid ionomer copolymers of ethylene and salts of methacrylic acid and nylony and other polyamides. Specialists in this Eaglehawks.

However, the preferred methods of coating are those that use dry binder or toners together with the required additives and modifiers. Such methods allow to use high dosage of thermoplastic components that are required for bonding under heating, to avoid dilution of the binder solvent (and the need for solvent removal and drying or curing the remaining binder) and create a clear picture without migration, which will not be wrapped in areas that should remain uncovered.

Examples of ways in which applied mostly dry thermoplastic binder are way gravure from the melt, a method of coating a dispersion of the melt or the method of applying a fibrous coating from the melt. The method of gravure printing from the melt can produce accurate and reproducible geometric or pictorial drawings coverage with the finest details, like pictures, and with the exact thickness. Specialists in the art will understand that the drawings of the coating depend on the details, the quality and depth of the engraved roller or plate for gravure printing and method of manufacturing it, the e clearly defined images of the cover, which can consist of any one or a mixture of the following: small particles, large particles, short fibers, long fibers, and continuous or discontinuous filaments. The drawings can be arbitrarily arranged or ordered: spirals, swirls and lines.

Additional methods of coating with dry binders are those methods that use thermal melting is obtained by electrostatic method drawings of carbon-containing thermoplastics or received by xerography drawings thermoplastic coatings containing a photoconductive dyes. Components of thermoplastic polymer of these electrostatically transferred toners are epoxy, hydrocarbon, acrylic, or polyamide resin. Examples of polymers used in these ways, using dry binders are copolymers of ethylene and vinyl acetate, polyamides, for example, various nylony, polycaprolacton, polyhexamethylenediamine, copolymers of styrene and isoprene, copolymers of styrene and butadiene, polyethylene, polypropylene, polyesters, e.g. polyethylene terephthalate, various poliefirami polyurethanes. Specialists in the art will understand that you can primewest, caking to reduce unwanted samozlepny and undesirable adhesion to other surfaces, stabilizers for regulating degradation during and after coating, additives reduce friction, to reduce friction, additives that reduce static charges, fillers and pigments.

Examples of pigments suitable for use in the present invention are titanium dioxide and zinc oxide. You can also use fillers, such as calcium carbonate and silicon dioxide. If you need color, you can use white pigments.

The usefulness of the present invention was demonstrated by the following examples:

1. Test methods

A. Aerobic cooking. Used twelve desktop devices for aerobic boiling with stirring. Mixing was carried out using two paddle mixers, each of which had six blades. Each device for cooking contained 2000 ml of a mixture consisting of 1800 ml "culture" fresh sludge from aerobic cooking and 200 ml of "raw material" return activated sludge (community schools). The cooking device was kept in a thermostat at 35oC. each device filed 200 ml obratnoystorone is whether rectangular pressed slices of thickness 0.010 " (0,254 mm), weighing approximately 1 g For tests used two instances of the samples. Each sample was placed in a nylon mesh bag tied to one of the blades, and rotated at a moderate speed. In each reactor were introduced additional air from an aquarium pump through the stone diffuser. Regulate the pH value. To maintain pH 7 was added acid or base. Was measured by the following weight: for samples original samples and the extracted residues; and for sludge total solids and volatile solids (flammable organic solids).

b. Anaerobic cooking. In one incubator was established sixteen outdoor devices for cooking at a temperature of 35oC. Each device for cooking contained 3650 ml of a mixture consisting of 2100 ml cooked slurry, 1500 ml of raw sludge and 50 ml acclimatized sludge. The test samples were rectangular pressed slices of thickness 0.010 " (0,254 mm) weighing approximately 1, two instances of samples for testing. Each sample was placed in a nylon mesh bag that has been inserted into the device for cooking, where he held a glass tube. Two cooking devices are kept similarly empty Naylor. The cooking device was shaken manually every day before to measure the volume of gas formed. 10, 20 and 30 days each device was opened for weighing samples and measurements next to slurry-pH, total solids and volatile solids (flammable organic solids).
