Definitions
- the invention relates to a touch-and-close fastener part, consisting of at least one plastic material with a plurality of hooking means integrally connected to a carrier, each in the form of a stem part provided with a head part, which protrudes over the carrier.
- the invention further relates to a diaper with at least one such touch-and-close fastener part.
- Diapers such as baby diapers or incontinence diapers, as they are used on the global market, are regularly designed as disposable diapers, which leads to considerable amounts of waste whose environmentally friendly disposal is regarded as problematic. It is true that disposable diapers are now available on the market as so-called eco-diapers in environmentally friendly variants that have a higher proportion of biodegradable components that are at least partially obtained from sustainable resources; alone, these eco-nappies, even if their manufacturing material is about 85% biodegradable, are not disposed of with organic waste, but with the residual waste that is usually intended for incineration in thermal power plants, which cannot exactly be described as environmentally friendly.
- a baby diaper or incontinence diaper consisting of an outer cover and an absorbent body connected to this cover, with a mechanical closure system acting between the outer cover and the absorbent body regularly in the form of correspondingly interacting adhesive closure parts of the absorbent body can be separated from the cover, which helps to protect the environment, especially if the absorption body is made from biodegradable cellulose materials, which can be mechanically separated from the other components, such as the outer cover of the diaper, and disposed of with organic waste.
- the respective outer shell of the diaper especially if it is made of decomposable plastic materials, can then be returned directly to the recycling cycle.
- Such baby or incontinence nappies regularly have laterally arranged closure tabs with which the respective nappy can be closed in a user-friendly manner after use.
- So-called hook and loop fasteners are regularly used for this purpose, consisting of a hook material on one side and loops or fibers on the other side which can be hooked on again in a detachable manner and which can also be formed by the surface material of the diaper itself.
- Such a closure system along with a method for producing the same is known from DE 196 46 318 A1 of the property right holder.
- High-quality, temperature-resistant plastic materials are used for the above-mentioned adhesive closure parts, which are regularly sewn or glued onto the closure flaps of a baby diaper, preferably polyamide, in particular polyamide granulate or polyamide-containing mixtures of thermoplastics.
- plastics although they are functionally reliable and proven in use, have the disadvantage that they are difficult to recycle precisely because of the plastic material mentioned. In particular, these cannot be done without Biodegrade more. Accordingly, their use in diapers also makes it more difficult to dispose of or process the diaper as a whole in an environmentally friendly manner, even if the other manufacturing or input material should be completely biodegradable.
- the invention is therefore based on the object of further improving the known touch-and-close fastener parts in such a way that they can be disposed of in an environmentally friendly manner if necessary, which also includes areas of application for such a touch-and-close fastener part, such as use in the field of diapers of any kind .
- an essential special feature of the touch-and-close fastener part according to the invention is that at least part of the plastic material used for it is biodegradable and/or bio-based.
- Such touch-and-close fastener parts are preferably used in a diaper whose manufacturing or input material is at least about 85% biodegradable and/or made up of bio-based materials.
- the biodegradable plastic material is preferably polycaprolactone, polybutyrate or polybutylene succinate. Even if the material polycaprolactone is based on petroleum products, this plastic can be readily biodegraded through the action of microorganisms such as fungi or bacteria. Furthermore, the degradation can be accelerated through the use of enzymes, with the biological degradation essentially by Oxidation and hydrolysis processes to the fission products water, carbon dioxide or methane and biomass takes place.
- Another biodegradable plastic material is polybutyrate; more precisely polybutyrate adipate terephthalate. This plastic can contain more than 30% bio-based carbon and has similar technical properties to LDPE (Low Density Polyethylene).
- polybutylene succinate which, based on fossil raw materials, belongs to the chemical compounds from the group of linear aliphatic polyesters; but can also be constructed from renewable raw materials. Its technical properties are in turn comparable to those of LDPE or polypropylene.
- Cellulose acetate can be used as the bio-based plastic material for the touch-and-close fastener part, which is one of the thermoplastics and can be composed of semi-synthetic fibers.
- Bio-based polyethylene can also be used, which can be produced petrochemically or from an alcohol such as bioethanol. If polyethylene furanoate is used, it is a 100% recyclable plastic material. All of the bio-based plastics mentioned above can be produced at least in part on the basis of renewable raw materials, which makes their use particularly environmentally friendly.
- the touch-and-close fastener part from a biodegradable plastic material that is bio-based.
- polyactides which are also known under the term polylactic acids, can be used as plastic materials for this purpose.
- Other representatives are polyhydroxyalkanoate and thermoplastic elastomers including thermoplastic styrene block copolymers (TPE-S). All of the plastic materials used make it possible to form the carrier of the touch-and-close fastener part in the manner of a plastic film which has a low melting point has, which enables an adhesive-free connection with third-party components by thermal joining, such as components of a diaper, in particular in the form of its closure tabs.
- the film thickness of the carrier is between 0.30 and 0.36 mm with a melting temperature of the material of 70°C.
- Such a touch-and-close fastener part can then have an average value of 2.34 N/cm 2 with a peel adhesion to a loop or loop material as a further touch-and-close fastener part of a removable touch-and-close fastener.
- Fig. 1 is a perspective view of a detail of a fastener part
- the touch-and-close fastener part shown in part in Fig. 1 has a large number of symmetrically constructed hooking means which are connected in one piece to a film-like carrier 10 and are each in the form of a stem part 14 connected to a head part 12.
- This touch-and-close fastener part is produced using a method in which a mouldable plastic material in a forming zone is fed between a roller-type pressure die and a roller-type forming die.
- the roller-like tools mentioned are driven in such a way that the carrier is formed in the shaping zone and conveyed in a definable transport direction.
- a sieve with individual mold cavities is fixed on the mold as the shaping zone, with the boundary walls lying opposite one another being continuously provided with a convex path for the stem part shaping of the respective stem part 14, seen at least in a longitudinal section of the respective mold cavity.
- the outwardly protruding head parts 12 can be post-calendered to form a common head plane after leaving the mold. Furthermore, for a resistant handle part 14, this is designed to be rotationally symmetrical, as is the head part 12.
- thermoplastically processable, biodegradable molding compositions containing fully biodegradable polyesteramides and thermoplastically processed cellulose derivatives as described in EP 0780439 A2.
- FIG. 2 shows a flat development of the outer cover 16 of a disposable diaper in the form of a baby diaper or incontinence diaper for adults.
- the outer shell 16 is tapered along its two opposite longitudinal edges 18 so that leg openings are formed for a user.
- the two longitudinal areas 20 forming a kind of cuffs are formed from an elastic material that is customary in diapers, which increases the wearing comfort for the user.
- Two tab-like closures or closure tabs 22 are attached in the usual way to the upper end of the outer shell 16 as viewed in the direction of FIG. 1, with which the diaper can be fixed to a user and rolled up and closed after use.
- the two closure flaps 22 have, in the direction of their two free ends, touch-and-close fastener parts 24 with a closure material, as exemplified in detail in FIG. 1 .
- a suitable absorber material for the absorbent body 22 is a fluid-permeable gauze cover, which comprises cellulose flakes inside the absorbent body 30, which are used to absorb fluid, regularly formed from the excretions of the diaper user. Further details on the construction of such a diaper can be found in the subsequently published DE 10 2019 006 683 A1.
- the carrier 10 which is formed from the respective plastic material in the manner of a film, has a low melting point, which enables an adhesive-free connection to third-party components by thermal joining, such as parts of a diaper in the form of the two closure flaps 22.
- the melting temperature is preferably here of the third component in the form of the respective closure tab 22 on the diaper is greater than the melting temperature of the carrier 10 of the touch-and-close fastener part made of the film material.
- the film thickness of the carrier 10 is selected to be between 0.30 mm and 0.36 mm with a melting temperature of approximately 70.degree.
- a peel adhesion to a loop or loop material as a further adhesive fastener part (not shown) of a removable adhesive fastener or a diaper top of an average of 2.34 N/cm 2 .
- the fastener system can also be formed by the looped or looped material of the surface material of the diaper. Overall, with a diaper constructed in this way, it can be largely biodegraded after use and/or constructed from bio-based materials.
- a polar component of > 0.01 mj/m results for Inzea 2 with a disperse content > 39 mj/m 2 .
- the polar component is > 6 mj/m 2 with a disperse component > 39 mj/m 2 .
