Description

15 20 25 30 microbiostatic material. Such material may be in the form of fibers or films, or as a wood product treated in order to achieve anti-rot properties.
Thus CCA has been claimed to have certain antimicrobial properties, whereas the effects are not clear; as set out above in CNlOl87ll67A and WOO7l35245Al, respectively. It must be pointed out, that in most cases either the carbamate group is washed away during regeneration or then easily removed from the cellulose during the processing step. In the present invention, we have found that it is preferable that high amounts of urea is remaining in the product and that the amount of carbamate group should be high (thus meaning less washing).
In WO20080529l3Al it is also disclosed a method and device for protecting crop plants wherein also carbamate compounds are disclosed. The meshed fabric disclosed therein may further contain cellulose.
In WO20l2lOl329 it is also disclosed a ground-cover mulch, which includes a web-formed vegetable fibre-bearing pulp, and wood distillate. The wood distillate includes birch-wood distillate. In addition, the disclosure also relates to a method for manufacturing a ground-cover mulch and the use of birch-wood distillate in ground-cover-mulch applications.
To summarize the background art shows that paper mulches has been investigated and used to a large extent.
However, industrial use of paper or cellulose films is usually limited by costs and by limited biodegradability.
Various components may be added to paper surface to adjust and control its properties, but it usually adds a lot of costs. There is therefore a need to solve one or more of the above problems. 10 15 20 25 30 The present invention addresses the problems of degradable paper based mulches. Due to wet conditions and high microbe contents in the soil, bio-based mulches such as paper needs to be treated in order to provide controlled rate of degradation. At the same time, the paper mulch or biofilm must be eco-friendly and have certain physical properties and be durable against water and wind. There is thus a need for an improved mulch. It has now surprisingly been found, that by using cellulose carbamate, preferably in fiber form and/or in film form, a mulch can be provided with such properties that solves one or more of the problems connected with cellulose based mulches.
Summary of Invention The present invention thus solves one or more of the above problems, by providing according to a first aspect a ground cover mulch which includes a paper substrate originating from vegetable fibre-bearing pulp which has been web-formed, wherein it also comprises a cellulose carbamate.
Also provided according to a second aspect of the invention is a method for manufacturing a mulch according to the first aspect comprising the following steps: a)providing a paper substrate originating from vegetable fibre-bearing pulp which has been web-formed, and b) applying on said paper substrate cellulose carbamate, optionally preceded by a filler addition step, which may already be in the web-forming process.
Also provided according to a third aspect of the invention is a method for manufacturing a mulch according to the first aspect comprising the following steps: c)providing a never-dried pulp or dried pulp, and 10 15 20 25 30 d)adding cellulose carbamate either at the wet end of a paper/board production line, or through surface sizing, or through coating, or through spraying, or through dusting in said line, optionally combined by adding one or more fillers, and optionally other functional chemicals such as strength additives, UV absorbents, hydrophobic agents, retention chemicals, biocides and nutrients.
Also provided according to a fourth aspect of the invention is the use of cellulose carbamate in a mulch, preferably according to the first aspect.
Also provided according to a fifth aspect of the invention is use of a mulch according to the first aspect in cultivation.
Detailed description of the invention It is intended throughout the present description that the expression "cellulose carbamate" embraces any cellulose carbamate that could be useful in a mulch context. The term CCA is also used interchangeably with said expression in the present disclosure.
The pulp mentioned in the present description, may be chemical pulp, mechanical pulp, thermomechanical pulp or chemi(thermo)mechanical pulp (CMP or CTMP). Said chemical pulp is preferably a sulphite pulp or a kraft pulp.
The pulp may consist of pulp from hardwood, softwood or both types. The pulp may e.g. contain a mixture of pine and spruce or a mixture of birch and spruce. The chemical pulps that may be used in the present invention include all types of chemical wood-based pulps, such as bleached, half- bleached and unbleached sulphite, kraft and soda pulps, and 10 15 20 25 30 mixtures of these. The pulp may be of dissolved type. The pulp may also comprise textile fibers. The pulp may also come from agriculture (e.g. potato, bamboo or carrot). The pulp may also be nanopulp (MFC). Also combinations of said pulp types are possible in the context of the present invention. The pulp may also contain synthetic fibers or biofibers such as PLA (Poly-lactic acid).
According to a further preferred embodiment of the product, i.e. the mulch, according to the first aspect of the invention contains additionally one or more fillers, such as a black filler, preferably carbon black, most preferred combined with a filler selected from the group comprising calcium carbonate, fly ash, talc, kaolin, precipitated carbonate, silica and aluminium oxides.
According to a further preferred embodiment of the first aspect of the invention the cellulose carbamate is present in the form of a continuous or discontinuous film, particles or a fiber, preferably when in fiber form with a fiber length less than about 100 mm, most preferred less than about 50 mm. When the cellulose carbamate is present in the form of a film or a fiber, preferably when in fiber form, the fiber length may also be less than about 10 mm, most preferred less than about 5 mm.
According to a further preferred embodiment of the first aspect of the invention the cellulose carbamate also may be fibrillated.
According to a further preferred embodiment of the first aspect of the invention the carbon black emanates from a non-fossil source, preferably from biomass or organic waste residues of non-fossil origin.
According to a further preferred embodiment of the method according to the second aspect the fibre-bearing pulp 10 15 20 25 30 which has been web-formed, has been made with a dry or wet laid process, preferably a wet laid process in which the cellulose carbamate has been added.
According to a further preferred embodiment of the method according to the third aspect the cellulose carbamate is added in the form of cellulose carbamate fibers, preferably with a fiber length less than about 100 mm, most preferred less than about 50 mm.
According to a further preferred embodiment of the method according to the third aspect the cellulose carbamate is added in the form of a film.
According to a further preferred embodiment of the method according to the third aspect spun fibers of regenerated cellulose carbamate are added as a reinforcement fiber or thread in the mulch.
Other techniques for obtaining a mulch according to the present invention could be e.g. through spinning. The CCA may be dosed in a paper machine (at the wet end) together with other chemicals, which may be normal fibers, process chemicals, etc. Most preferable, the CCA contains N- molecules and thus bears a higher bioactivity. It may in addition be possible to have low and high amounts of the filler(s). The CCA may further be present in other shapes/forms such as hollow fibers, fibrillated fibers, nanofibers, flat fibers and micronized fiber (with low aspect ratio).
The mulch according to the present invention may be regenerated product and the CCA may be in form of fibers or films or as a composite on top on e.g. bioplastics or paper.
The final product may as set out earlier preferably contain a filler, e.g. a dark filler which provides a colored version. The regenerated substrate may also, which is 10 15 20 preferred, have sufficient wet strength and mechanical properties which is sufficient for industrial agriculture.
It should also be mentioned that CCA has bioactive characteristics and thus provides the mulch with features that it becomes less prune to degradation and can also better stand firm against an attack from microorganisms.
Preferred features of each aspect of the invention are as for each of the other aspects mutatis mutandis. The prior art documents mentioned herein are incorporated to the fullest extent permitted by law. The invention is further described in the following examples the only purpose of which is to illustrate the invention and are in no way intended to limit the scope of the invention in any way.
In view of the above detailed description of the present invention, other modifications and variations will become apparent to those skilled in the art. However, it should be apparent that such other modifications and variations may be effected without departing from the spirit and scope of the invention.
