Definitions
- the invention relates to a method for producing a fiber mat that promotes cult plant growth by assembling natural fibers and additives, for which binder and / or elevated temperatures and / or increased pressure can be used with any technique.
- binder and / or elevated temperatures and / or increased pressure can be used with any technique.
- the object of the invention is therefore to provide a technical solution by means of which the shortcomings of the known prior art are overcome.
- additives such as plant nutrient-containing and moisture-storing agents or plant seeds
- the task is to develop procedural requirements for the acceleration or deceleration of the effect of individual components of the fiber mat that promotes the growth of crops.
- Biodegradable nonwovens preferably in the form of needled nonwovens, random fiber nonwovens, felts, carded or carded nonwovens made of natural fibers, and / or papers or foils are used. If necessary, pre-consolidation is already carried out by using binders, by pressing or upsetting, tempering, needling, felting.
- Biodegradable materials for example aqueous emulsions of natural rubber, are preferably used as binders. It is also possible to use mixtures of different binders as binders.
- Agents which contain plant nutrients for example organic, mineral or chemical fertilizers with different levels of nitrogen, phosphorus and potassium, can be used as further additives.
- plant nutrients for example organic, mineral or chemical fertilizers with different levels of nitrogen, phosphorus and potassium
- additives can be used as additives which equally contribute to the manure nutrition and the pH value regulation and at the same time influence the conversion of the other plant nutrients into a form available to the plants and their absorption by the plant roots.
- such substances can be used as additives which promote ion exchange and, if necessary, can also mobilize available micronutrients such as sulfur, iron, copper and the like.
- water-storing materials can also be used, for example copolymers and superabsorbents, or natural or artificial mineral material with a pronounced pore volume, such as expanded perlite, expanded clay, expanded slate, pumice stone and the like.
- the seeds of desired crop plants can also be introduced into or fixed to the fiber mat as additives.
- binders are applied after the additives have been applied.
- An embodiment of the invention provides that the additional nonwoven fabric to be used to cover the additives is previously prepared with binders. However, these binders can also be applied to the additives already applied immediately before the additional nonwoven is applied. For the sufficiently stable connection of the nonwoven fabric absorbing the additives with the nonwoven fabric covering the additives, it is provided that the additional nonwoven fabric after application to the additives by mechanical means such as needles, sewing, felting and / or pressing, and / or by means of thermal treatment with which the non-woven fabric containing the additives is connected.
- the steps for forming a fiber mat which promotes cultivation are used several times, so that a fiber mat in sandwich construction is obtained.
- the outer layers can either be the pre-compressed fiber mats or the sides of the fiber mats prepared with binders.
- natural fibers and additives can be joined together using binders and / or elevated temperatures and / or increased pressure in such a way that the binders to be used are foamed in a first step in order to produce a kid mat that promotes the growth of kid plants.
- the additives are then intimately combined with the foamed binder.
- the binder foam containing the additives and the nonwoven fabric are brought together, whereupon in a final work step at least one of the aftertreatment techniques, such as stripping, drying at suitable ambient temperatures, pressing or compressing, laying on another nonwoven fabric, laying on a biodegradable perforated film, thermal aftertreatment on increased Temperatures.
- the additives used in the density and grain size determined as optimal as a separate layer in the bevel mat or to be deposited thereon it can be helpful to coat at least one of the additives used with hydrophobicizing agents, for example by biodegradable wax emulsions or by emaciated emulsions of the biodegradable binder to be used. It is also possible to use moisture-inhibiting agents between the components of the chamfer mat and at least one additive to be used with a delay in action.
- the moisture-inhibiting agent can be used, for example, between the additive to be used to slow down the action and the remaining part of the fiber mat become.
- Biodegradable perforated films can also be used as a moisture-inhibiting agent.
- hygroscopic agents for example as a separate material layer, are also introduced to accelerate the action between components of the fiber mat and at least one of the additives to be brought into effect in an accelerated manner. In this way, it is achieved that moisture to be taken up by the liquid or the moisture stored in parts of the additives is primarily absorbed by the hygroscopic agents and brought into direct contact with the additives to be used in an accelerated manner.
- the advantages of the invention are summarized in the now available fiber mat which promotes the growth of cultivated plants and which can already be tailored during production to the needs of the particular soil to be revitalized on the one hand and to the requirements of the developing crop plants on the other hand.
- This ensures that after the single application of the appropriately equipped fiber mat with simultaneous suppression of harmful plant growth while largely dispensing with the use of crop protection agents, the essential requirements for the germination and growth of the desired kidtur plants are guaranteed.
- the advantage of the technical solution created also lies in the fact that it is now possible to dispense with subsequent processing steps to ensure the growth of crops in the decisive growth phases. This concerns, for example, the suppression of harmful plants that is no longer required, or the supply of nutrients and moisture for the crop plants to be developed, in each case through separate work processes.
- Fig. 7 the schematic sectional view of a chamfer mat in
- Sandwich design consisting of two fiber mat layers, two additive layers at least partially dispersed in the fiber layers and three binder layers;
- a raw fiber mat made of natural fiber fleece is pre-consolidated by a rolling process and compressed to about 40% of its original thickness.
- a binder in the form of an aqueous emulsion of natural rubber is then sprayed onto the top of the consolidated nonwoven. After the binder has set or has set, the pre-consolidated raw fiber mat is turned over.
- various additives in the form of finely divided plant nutrients, in the form of finely divided expanded perlite as a water-storing medium and in the form of finely divided dolomite as a pH value regulator are mixed in a mixture on the binder and then dispersed by mechanical shaking in the upper layer wetted by the binder .
- the additives are then fixed in the fiber mat by reapplying binder.
- an additional raw fiber mat is applied to the fiber mat prepared with additives before the binding agent is applied, this additional mat being able to be subjected to a pre-compression beforehand.
- this additional mat can also be a paper layer, for example.
- the two fibrous layers of the fiber mat are connected to one another by needling or by sewing before the fiber mat is cut and made into wrapping bales.
- a fiber mat which promotes growth of the plant is produced by first coating a raw fiber mat 2 on one side with binder 1 and then turning it over. This is followed by the application of the selected additive mixture 3, if appropriate with the seeds of the crop to be developed, onto the turned raw fiber mat 2. Then the top of the raw fiber mat 2 is again provided with the additives 3 dispersed therein with a binder layer 1. Even before the binder 1 used has set, another layer of the pre-compressed nonwoven fabric 2 is placed on top of which an optionally varied mixture of additives 3 is again applied and dispersed. Finally, the chamfer mat produced is protected against loss of additives 3 in that a final application of binder 1 is carried out, and if necessary the production can be accelerated by applying pressing forces and elevated temperature.
- Example 3 Example 3:
- a fiber mat which promotes cultivation of plants is produced by first providing the prepared raw fiber mat, the binder to be used and the prepared mixture of additives separately from one another.
- the binder is foamed to increase the volume and processed into an additive-containing binder foam by using the selected quantity of additives.
- This prepared foam is then brought together with the raw fiber mat and subjected to a mechanical and / or thermal aftertreatment before trimmed stacks or wrapped bales are produced by means of finishing processes.
- the mechanical aftertreatment provides for the wiping off of the foam which has not been taken up and for the return of these excess amounts to the corresponding storage container.
- the desired impregnation of the raw fiber mat with the prepared binder foam can be supported with mechanical means, such as shaking, compressing or evacuating, for the purpose of the pore volume of the fiber mat failing. Hardening can be accelerated by using higher temperatures.
- a fiber mat is produced by first applying binder to the raw fiber mat provided in accordance with exemplary embodiments 1 and 3. Additives are then applied to this binder layer, it being possible to use an additive-containing binder foam instead of the additive mixture. Before further processing of the fiber mat, a homogeneous layer of finely divided calcium compounds is now applied as a pH-regulating component before the fiber mat is completed by applying a further fibrous layer or a further binder layer.
- Example 5 Example 5:
- a nitrogenous fertilizer is used as an additive in a separate layer, analogous to embodiment 4.
- the nitrogenous additive is prepared beforehand with a wax emulsion and thus made hydrophobic for a certain period of time.
- an anti-moisture agent is first applied as a separate layer.
- this layer consists of a bentonite-containing earth-moist clay layer, to which the nitrogen-containing additive is applied.
- a nitrogenous fertilizer is used as an additive in a separate layer, analogous to embodiment 4.
- the nitrogenous additive is prepared beforehand with a hygroscopic agent and thus prepared for the accelerated effect.
- a moisture-promoting agent is first applied as a separate layer. After the completion of the fiber mat in the form already described, its application is carried out in the reverse position, so that even if the entry of surface moisture is deficient, the mobilization of nitrogen is initially promoted. It is therefore available at an early stage of development of the crop to be promoted.
