Description
2~0~33 The present invention relates to a fleece material made of natural fibers and to uses thereof.
There is presently an increasing requirement or even a demand to use ecologically safe materials in all sorts of fields. Moreover, commercial recycling programs are now in place so that the recyclability of materials is an important factor.
For example, the new packaging regulations are forcing trade and industry to employ returnable shipping packages of all types. The packaging ma~erial must then be recycled, burned or brought to a dump at a substantial cost. Of particular concern is waste removal and recycling of packaging materials consisting, in whole or in part, of a synthetic material such as polyvinyl chloride, polyethylene or polystyrene. For example, the burning of polypropylene or polyethylene to produce long-distance heat is not economical since the combustion plants must be equipped with expensive waste gas filters. Moreover, about 100 kg filter ash is produced per ton of waste material.
The filter ash is contaminated with a variety of potentially harmful substances and must usual~y be disposed of separately in the form of compressed cakes.
The above-mentioned problems cannot be overcome by simply using packaging made of cardboard and the like.
Fragile goods, such as glass, and complex electronic equipment, such as computers or televisions, require packaging which offers sufficient shock absorbency.
Furthermore, some goods must be protected by the packaging against climatic conditions including moisture and temperature.
While returnable packages are being used more frequently, the packages are subject to wear and the problem of disposal ultimately continues to exist.
There is a trend towards the use of natural materials ~or insulation in buildings and, in particular, in residential dwellings. However, adequate insulation against heat, cold and noise should preferably not be sacrificed in order to save energy and a~oid noise pollution. Examples of natural materials include mineral 210~3~
wool felt and felt laminated with aluminum foil, glass fiber fleece (particularly for insulating panels), fleece webs made of sheep's wool, shredded newspaper (protected with boric salts against rotting, pest infestation and fire and inserted as flocks in partitions) and cork mats.
Mineral wool fibers and glass fibers are very brittle and tend to break during processing into fiber fragments having a diameter of less than 2 ~m and a length of less than 5 ~m. These small particles can lodge in the lungs where they can neither be discharged nor broken down.
The occurrence of these small particles led, for example, to the ban of asbestos.
Another disadvantage of these natural insulating materials is that they are usually available only in limited quantities and can be too expensive.
It is an object of the present invention to provide a material that can be easily disposed of or composted after one or more uses, while meeting the current requirements with respect to stability in packaging material, insulating properties, and the like.
According to one aspect of the present invention, there is provided a fleece material made of natural material, comprising cotton or cellulose fibers which are pinned together to stabilize and form a fleece mat.
The invention will be more readily understood from the following description of preferred embodiments thereof given, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a sectional view of a first embodiment of a fleece material according to the present invention;
Figure 2 is a sectional view of a second embodiment of a fleece material according to the present invention;
Figure 3 is a sectional view of a third embodiment of a fleece material according to the present invention;
and ~ 0~33 Figure ~ i5 a sectional view of a fourth embodiment of a fleece material according to the present invention.
The fleece material of the present invention consists of cotton fibers or cellulose fibers which are pinned together to stabilize the fleece. A fleece material of this type can be broken down completely in a biological process and has sufficient rigidity for use in the packaging of electric appliances, machine parts, computers, household appliances, furniture, bottles, etc., and as a filler or insulating material in conventional packaging.
Moreover, the fleece material is odourless.
Preferably, the fleece material, has a weight in the range of about 300 to 3000 g/m2. The material can be supplied in rolls or can be adapted to the specific packaging requirements.
The fleece material shown in Figure 1 consists of a fleece mat 1 made of cotton fibers or cellulose fibers which are sewn together to form an irregular felt. The fleece material is suitable for use in the form of a mat 1 or additional measures may be implemented to maximize its properties for the intended purpose.
In a preferred embodiment, the fleece material is provided, on at least one outer side, with a layer of a biologically decomposable agent, such as potato starch and/or alginate and/or the like, which is applied by wetting and subsequently drying the decomposable agent on the surface of the fleece. The surface of the fleece is sealed after the drying process so that no fibers can escape from the fleece material composite. In addition, the fleece material becomes very elastic and fle~ible as a result of the coating. In particular, the fleece material has good damping and insulating properties. The fleece material composite is particularly resistant to penetration by sharp objects, corners and edges of objects acting on the materialO

According to one aspect of the present invention, there is provided a fleece material made of natural material, comprising cotton or cellulose fibers which are pinned together to stabilize and form a fleece mat.
The invention will be more readily understood from the following description of preferred embodiments thereof given, by way of example, with reference to the accompanying drawings, in which:
Figure 1 is a sectional view of a first embodiment of a fleece material according to the present invention;
Figure 2 is a sectional view of a second embodiment of a fleece material according to the present invention;
Figure 3 is a sectional view of a third embodiment of a fleece material according to the present invention;
and ~ 0~33 Figure ~ i5 a sectional view of a fourth embodiment of a fleece material according to the present invention.
The fleece material of the present invention consists of cotton fibers or cellulose fibers which are pinned together to stabilize the fleece. A fleece material of this type can be broken down completely in a biological process and has sufficient rigidity for use in the packaging of electric appliances, machine parts, computers, household appliances, furniture, bottles, etc., and as a filler or insulating material in conventional packaging.
Moreover, the fleece material is odourless.
Preferably, the fleece material, has a weight in the range of about 300 to 3000 g/m2. The material can be supplied in rolls or can be adapted to the specific packaging requirements.
The fleece material shown in Figure 1 consists of a fleece mat 1 made of cotton fibers or cellulose fibers which are sewn together to form an irregular felt. The fleece material is suitable for use in the form of a mat 1 or additional measures may be implemented to maximize its properties for the intended purpose.
In a preferred embodiment, the fleece material is provided, on at least one outer side, with a layer of a biologically decomposable agent, such as potato starch and/or alginate and/or the like, which is applied by wetting and subsequently drying the decomposable agent on the surface of the fleece. The surface of the fleece is sealed after the drying process so that no fibers can escape from the fleece material composite. In addition, the fleece material becomes very elastic and fle~ible as a result of the coating. In particular, the fleece material has good damping and insulating properties. The fleece material composite is particularly resistant to penetration by sharp objects, corners and edges of objects acting on the materialO
3~33 In the embodiment shown in Figure 1, the upper side and the underside of the fleece mat 1 are provided with layers 2,3 of potato starch, alginates or the like which seal the fleece while forming a smooth surface.
Accordingly, panels with smooth outer surfaces are created.
In particular, the fibers near the surface of the fleece mat 1 end below or within the respective layers 2,3 so that they do not protrude beyond the layers 2,3.
In the embodiment depicted in Figure 2, a fleece mat 1 is provided with a surface-sealing layer 3 on the underside of the fleece mat 1. A reinforcing layer 4 of very dense fleece, reinforcing web, fabric or bundle of biologically decomposable fihers, impregnated with a hydrophobic coatinq 5 on the side remote from the fleece mat 1 is applied to the upper side of the fleece mat 1.
The coating 5 can be provided substantially on the surface of the layer 4 or can completely or partially penetrate the reinforcing 4. The reinforcing layer 4 can be attached to the surface of the fleece mat 1 by gluing, pinning or any other suitable joining technique. The layer 3 of the embodiment of Figure 2 can be replaced by a reinforcing layer 4 with or without a coating 5. The fleece material provided with a reinforcing layer 4 is particularly suitable as a reusable packaging material. The hydrophobic coating 5 provides protection against moisture.
Referring now to Figure 3, a reinforcing web, fabric or bundle of fibers 7 is embedded between two fleece layers 6,8. There is no surface treatment in this example of an embodiment.
The fleece layers 6,8 can be connected to the reinforcing web 7 by pins, gluing with a biologically decomposable adhesive, such as potato starch, sewing, weaving and/or stitch-weaving.
The fleece material shown in Figure 4 is particularly suitable in building applications. The fibers of the fleece mat 1 are treated with a hydrophobic agent, an anti-rotting agent, a fungi and/or pest control agent, 21Q~ 33 and/or a fire-resistant agent. Preferably, the fire-resistant agent provides a fireproofing level ~1 or B2 according to DIN 4102. The surface of the treated fleece mat 1 is covered on one side with aluminum foil 9 which can be glued, sewed or fastened by another suitable method to the fleece mat 1.
The fleece material o~ the present invention has been found to provide heat and/or noîse insulation and is useful in roof and wall insulations in the building industry, impact noise and floor heat insulation as well as pipe, fitting and air duct insulations.
Vapour barriers are not required in cotton fiber insulation systems according to the present invention.
Cotton protects against damage to buildings because of its ability to absorb and release moisture.
Thermal conductivity values of about 0.35 to 0.40 can be achieved with the fleece material of the present invention. The insulating qualities are similar to those of other insulating materials.
For certain applications, it is advantageous to bleach the cotton or cellulose fibers. The bleaching can be done prior to or after forming the fleece material into a mat 1.
The fleece material of the present invention has a very high absorbency. Accordingly, the fleece material is particularly suitable as packaging for breakable liquid containers, whereby any liguid flowing out of a container is immediately absorbed by the packaging material.
Moreover, the fleece material is useful as a polishing or cleaning cloth, in particular, after it has already been used as packaging material.
A fleece mater.ial for applications of this type is preferably made lightweight with a weight in the range of about 50 to 500 g/m2.
The fleece materials of the present invention can be used, in most cases, as a suitable replacement for plastic foil, air-bubble cushioning film, corrugated board, .

21~13~
wrapping paper and similar packaging materials. The fleece materials can be supplied as rolls or can be cut to size.
Many combinations, with respect to reinforcements and coatings or impregnations, are possible.
When the fleece material is impregnated with a biologically decomposable agent such as starch or alginate and then dried, relatively hard molded pieces are obtained which can also be precisely cut to shape. They are preferably used as cushioning material for fragile goods and can replace molded polystyrene foam packaging material.
If required, two or more fleece mats or panels can be glued together, depending on the thickness required for the molded article. The desired shape can then be cut out of the glued mats by punching. The cut out shapes can then be treated, if required.
The fleece material, in particular when it has already been used once or more as packaging, can be shredded or cut to form a filler. The fleece material filler is a suitable substitute for materials such as chips, cubes, granulated material or the like made of a synthetic material, such as polystyrene foam or other materials usually used for packaging goods.
The fleece material of the present invention has a variety of uses, is recyclable and can be disposed of without difficulty as it can be biologically decomposed without harmful residues. The material can, if required, be used as a substitute for peat after it has been reduced or cut.
It is also advantageous to use the fleece material as a water ~torage mat, in particular, for horticulture applications. For example, potted plants or plant bulbs can be placed on water-soaked mats, thereby eliminating the requirement for constant watering of the plants.
The fleece material is also suitable as a mat for absorbing oil.

Accordingly, panels with smooth outer surfaces are created.
In particular, the fibers near the surface of the fleece mat 1 end below or within the respective layers 2,3 so that they do not protrude beyond the layers 2,3.
In the embodiment depicted in Figure 2, a fleece mat 1 is provided with a surface-sealing layer 3 on the underside of the fleece mat 1. A reinforcing layer 4 of very dense fleece, reinforcing web, fabric or bundle of biologically decomposable fihers, impregnated with a hydrophobic coatinq 5 on the side remote from the fleece mat 1 is applied to the upper side of the fleece mat 1.
The coating 5 can be provided substantially on the surface of the layer 4 or can completely or partially penetrate the reinforcing 4. The reinforcing layer 4 can be attached to the surface of the fleece mat 1 by gluing, pinning or any other suitable joining technique. The layer 3 of the embodiment of Figure 2 can be replaced by a reinforcing layer 4 with or without a coating 5. The fleece material provided with a reinforcing layer 4 is particularly suitable as a reusable packaging material. The hydrophobic coating 5 provides protection against moisture.
Referring now to Figure 3, a reinforcing web, fabric or bundle of fibers 7 is embedded between two fleece layers 6,8. There is no surface treatment in this example of an embodiment.
The fleece layers 6,8 can be connected to the reinforcing web 7 by pins, gluing with a biologically decomposable adhesive, such as potato starch, sewing, weaving and/or stitch-weaving.
The fleece material shown in Figure 4 is particularly suitable in building applications. The fibers of the fleece mat 1 are treated with a hydrophobic agent, an anti-rotting agent, a fungi and/or pest control agent, 21Q~ 33 and/or a fire-resistant agent. Preferably, the fire-resistant agent provides a fireproofing level ~1 or B2 according to DIN 4102. The surface of the treated fleece mat 1 is covered on one side with aluminum foil 9 which can be glued, sewed or fastened by another suitable method to the fleece mat 1.
The fleece material o~ the present invention has been found to provide heat and/or noîse insulation and is useful in roof and wall insulations in the building industry, impact noise and floor heat insulation as well as pipe, fitting and air duct insulations.
