Definitions

• the present invention relates to funeral articles made of biodegradable materials and their use for burial.
• body bags made of particularly strong material, such as e.g. made of high-strength polyester filaments.
• the polyester is composed of a polyol and of an aromatic polycarboxylic acid and additionally composed of an aliphatic polycarboxylic acid.
• DE 10 2005 024 791 A1 describes a shaped body that can be used as a burial urn or as an ash capsule.
• This consists of a fiber composite material with a reinforcement and a binder, which are each constructed of biodegradable material.
• polylactic acid is proposed as a binder.
• DE 197 44 331 A1 discloses a coffin or urn, which are formed as a molded part of a biologically residue-free degradable natural material-based plastic. A surface portion thereof is preferably transparent, and polylactic acid is proposed as the plastic therefor.
• Thermoplastic polyesters derived from ⁇ -caprolactone are described in U.S. Pat DE 600 25 619 T2 disclosed. These are suitable, among other things, for shrouds.
• the layer construction is composed of a film-like plastic layer and of a textile layer, of which the textile layer is preferably made of biodegradable fibers and / or biodegradable secondary fibers and the film is also preferably constructed of biodegradable materials.
• the layer construction can be used, inter alia, in funeral services.
• Object of the present invention is to provide funeral articles, on the one hand to the funeral are visually handsome and have sufficient strength, and on the other hand biodegrade without residue after burial within a short time.
• the invention relates to funeral articles containing at least one textile surface containing threads of aliphatic polyester.
• the funeral articles according to the invention contain textile surfaces which are constructed from threads.
• the term "textile surface” is to be understood as meaning a fabric made up of threads that has been produced by a textile surface-forming technique. Examples of this are fabrics, scrims, knits, knitted fabrics or nonwoven fabrics (non-wovens).
• Filaments in the sense of this description may be filament yarns, spun yarns, threads or preferably monofilaments.
• the filaments building up the burial article typically have titers in the range of 550 dtex to 80,000 dtex.
• the cross-sectional shape of the threads used according to the invention may be arbitrary, for example round, oval or n-cornered, where n is greater than or equal to 3.
• Non-round monofilaments whose cross-sectional area is a regular or irregular n-corner with n ⁇ 3 are particularly preferably used.
• the funeral articles according to the invention are particularly suitable as death shirts, coffin linings or body bags. In these applications, in addition to a sufficient strength before funeral a good degradability of the material after burial desired.
• aliphatic polyesters or mixtures thereof are used as thread-forming materials for producing the threads which make up the burial articles according to the invention. These are known to be biodegradable polymers. In addition, other biodegradable threads may be present in the funeral article according to the invention, for example threads of cotton or of cellulose. There are also combinations of the texile surface with others Elements possible, for example, with films of biodegradable material.
• Aliphatic polyesters are polymers derived from an aliphatic monomer having a carboxyl group or a polyester-forming derivative such as a carboxylic acid ester group, and a hydroxyl group or a polyester-forming derivative such as an ether group; or they are polymers derived from a combination of an aliphatic monomer having two carboxyl groups or polyester-forming derivatives thereof with an aliphatic diol or polyester-forming derivatives thereof.
• aliphatic polyester includes in addition to exclusively composed of aliphatic and / or cycloaliphatic monomers polyesters and those polyesters, in addition to aliphatic and / or cylcoaliphatic structural units small proportions of aromatic structural units, as long as the biodegradability of these polyesters is not adversely affected.
• Polymers derived from aliphatic monomers having a carboxyl group and a hydroxyl group are also referred to as polyhydroxyalkanoates.
• polyesters of this type are polyhydroxybutyrate, poly (hydroxybutyrate-co-hydroxyvalerate), poly (hydroxybutyrate-copolyhydroxyhexanoate), polyglycolic acid, poly (epsilon-caprolactone), and most preferably polylactic acid.
• Examples of preferred aliphatic polyesters derived from a combination of aliphatic dicarboxylic acids with an aliphatic dialcohol are poly (butylene succinate), poly (ethylene succinate), poly (butylene adipate), poly (ethylene adipate), poly (tetramethylene adipate / terephthalate) ,
• the aliphatic polyesters used according to the invention may be of different types. Such polymers are thermoplastic and known to those skilled in the art as biodegradable polymers.
• Particularly preferably used aliphatic polyesters are homopolymers or copolymers derived from lactic acid and optionally copolymerizable with aliphatic comonomers.
• polyester threads used according to the invention for constructing the textile surface of the funeral article may optionally contain further additives in addition to the polymer or polymer mixture.
• hydrolysis stabilizers examples include hydrolysis stabilizers, processing aids, antioxidants, UV stabilizers, plasticizers, lubricants, pigments, dyes, electrical conductivity-imparting additives, viscosity modifiers, crystallization accelerators or biocides.
• polyester threads used according to the invention consist mainly of the aliphatic polyester.
• the level of additives typically ranges from less than 10% by weight, preferably less than 5% by weight.
• the funeral articles according to the invention are distinguished not only by sufficient strength but also by outstanding biodegradability, in particular excellent biodegradability.
• the textile surfaces and the funeral articles made therefrom can be produced in a manner known to those skilled in the art and in the usual way to process. Examples of the manufacture and use of the funeral articles can be found in the above mentioned documents.
• cremation funeral articles of the invention are excellent, as they burn easily and without residue.
• an aliphatic polyester (Nature Works Polylactide Resin 6400D, Fa. Nature Works LLC, Minnetonka, MN 55345 USA) was used in Schnitzel form. After drying of the raw material, it was melted in the extruder, fed to a spinning pack via a spinning pump, spun through fine bores into monofilaments, quenched in a water bath, then stretched in three stages under the action of heat, treated with preparation as a processing aid and wound up.
