This application is related to and claims priority benefits from German Patent Application No. DE 10 2016 209 046.1, filed on May 24, 2016 and entitled METHOD FOR THE MANUFACTURE OF A SHOE SOLE, SHOE SOLE, SHOE AND PRE-MANUFACTURED TPU ARTICLE, the content of which is hereby incorporated herein in its entirety by this reference.
The present invention relates to a method for the manufacture of a shoe sole, a corresponding manufactured sole, and a shoe comprising such sole. The invention further relates to a pre-manufactured article comprising thermoplastic polyurethane (TPU), in particular an outsole.
The conventional manufacture of shoe soles, in particular of sport shoes, generally involves processing various plastic components. Recently, it has become known to produce shoe soles or parts thereof such as midsoles from particles of expanded thermoplastic polyurethane (eTPU). Such particle midsoles can be bonded to standard outsoles made of rubber or any other material using adhesives. However, the use of adhesives is disadvantageous for the environment and can be harmful for workers due to solvents or other substances contained in such adhesives. Moreover, it also involves a considerable amount of manual labor.
One option to avoid or at least reduce the use of adhesives is to provide shoe soles from plastic components, which can be molded together by applying steam or other energy transferring media. Such techniques are for example disclosed in EP 2 649 896 A2, WO 2005/066250 A1, WO 2012/065926 A1, DE 10 2011 108 744 A1, and EP 2 984 956 A1. Further prior art in this regard is disclosed in EP 2 767 181 A1, WO 2007/082838 A1, WO 2008/087078 A1.
However, at present it is extremely difficult, if not almost impossible, to bond a midsole made from expanded TPU particles to a rubber outsole without involving adhesives. Therefore, one approach is to use a different outsole material that is more compatible with the material of the expanded TPU particles of the midsole, such as (non-expanded) TPU. When trying to connect a TPU outsole during molding with the expanded TPU particles, the TPU of the outsole may, however, start to melt, deform and/or bleed, which leads to unsatisfactory products.
It is therefore a problem underlying the present invention to overcome the above disadvantages when manufacturing a shoe sole.

Possible embodiments of the present invention are further described in the following detailed description, with reference to the following figures:
The above problem is at least partly solved by the subject matter of the independent claims of the present invention.
In one embodiment, the invention provides a method for the manufacture of a shoe sole, comprising the following steps:
In another embodiment, the invention provides a method for the manufacture of a shoe sole, comprising the following steps:
In a further embodiment, the invention provides a method for the manufacture of a shoe sole, comprising the following steps:
The inventors of the present invention have surprisingly found that an outsole material that comprises, in addition to TPU, an additive, which increases the viscosity, may lead to an increase of the viscosity of the TPU material of the article. The inventors of the present invention have surprisingly further found that an outsole material that has been subjected to an annealing step may lead to an increase of the melting onset temperature. As a result, there is less or even no melting/deforming/bleeding during or after molding the TPU article to a midsole made from expanded TPU (eTPU) particles.
It will be apparent to the skilled person that whilst the terms melting/deforming/bleeding are distinct terms they are being interchangeably used in the context of this application to describe an effect that could be attributable, wholly or in part, to each of the mechanisms.
The pre-manufactured article can be an outsole but also other articles such as reinforcing TPU components for the midsole are possible.
The additive can be provided during injection molding of the pre-manufactured TPU article.
The pre-manufactured TPU article can comprise the additive in an amount of 1 to 15% by weight, in particular 1 to 10% by weight, preferably 1 to 5% by weight, more preferably 2 to 3% by weight, based on 100% by weight of the TPU material of the pre-manufactured TPU article.
The additive can increase the viscosity to such an extent that a deformation of the pre-manufactured TPU article is avoided, when the particles and the pre-manufactured article are connected in step c. In particular, when the particles and the pre-manufactured article are connected in step c, a processing temperature is provided by the interconnecting medium. If the melting onset temperature of the pre-manufactured TPU article is low enough, relative to the provided processing temperature, then undesirable deformation of the pre-manufactured TPU article will occur. Thus, when the processing temperature is sufficient to cause melting of the pre manufactured TPU article the additive increases the viscosity to such an extent that undesirable deformation of the pre-manufactured TPU article is avoided, when the particles and the pre-manufactured article are connected in step c.
In a preferred embodiment, the annealing step has been carried out to increase the melting onset temperature to such an extent that an undesirable deformation of the pre-manufactured TPU article is avoided, when the particles and the pre-manufactured article are connected in step c. Preferably, the melting onset temperature is increased by 5 to 50° C., in particular 10 to 30° C., or by 5 to 20° C.
In an exemplary embodiment, the annealing step has been carried out at a temperature in the range of from 100 to 150° C., in particular from 120 to 140° C. In another exemplary embodiment, the annealing step has carried out for a time period of from 2 to 20 hours, in particular from 5 to 17 hours.
It is possible that the interconnecting medium comprises one or more of the following: pressurized steam, an electromagnetic radiation, and a gaseous bonding agent. In exemplary embodiments, during step c. the particles of the expanded TPU material are heated by the interconnecting medium to a temperature between the melting onset temperature and the peak melting point of the expanded TPU material. For example, during step c. the particles of the expanded TPU are heated up to a range of from 100° C. to 5° C. below the melting point of the expanded TPU material, in particular from 80° C. to 5° C. below the melting point of the expanded TPU material, preferably from 60° C. to 5° C. below the melting point of the expanded TPU material, more preferably from 40° C. to 5° C. below the melting point of the expanded TPU material.
The additive may comprise an isocyanate group.
A further aspect of the invention concerns a sole obtainable or produced by any of the methods described above. Another aspect of the invention concerns a shoe, in particular a sports shoe, with a sole as described above. Finally, the invention concerns a pre-manufactured article, for example, an outsole, comprising TPU material and an additive increasing the viscosity of the TPU material. Furthermore, the invention concerns a pre-manufactured article, for example, an outsole, comprising TPU material, wherein the TPU material has been subjected to at least one annealing step at a temperature in the range of from 100 to 150° C. and for a time period of from 2 to 20 hours.
The invention is further described in the following description, the embodiments, examples, the figures, and the claims.
The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described.
In the following detailed description, preferred examples and embodiments of the invention are described. However, this is not to be construed as limiting the scope of the present invention, which is defined in the attached claims. Moreover, while various aspects of the examples and embodiments are described below, it is apparent for the skilled person that other combinations thereof, even if not explicitly mentioned, are also to be encompassed.
The polymer used for the production of both, of the pre-manufactured article and the expanded polymer particles, comprises a TPU. Generally, polyurethanes are produced by reaction of multifunctional isocyanates with polyols. TPUs are specific polyurethanes, which are thermoplastic and contain linear segmented block copolymers including hard and soft segments. TPU can contain the reaction products of a polyester polyol or polyether polyol with an isocyanate component. TPUs are well known in the art and commercially available on the market. TPU can be, for example, injection-molded to produce manufactured articles. TPUs are also known and available on the market in form of expanded or foamed TPU particles, which can be further processed by, for example, molded to produce manufactured articles.
The pre-manufactured article used in the methods of the invention can be produced from any TPU material by any method known in the art. Preferably, the article is produced by melting TPU, for example, melting TPU, within the plasticizing unit of an injection molding machine, and then injecting the material into a mold to form the pre-manufactured article. However, other molding techniques are possible.
The particles of expanded TPU (eTPU) used in the methods of the invention can be produced from any TPU material by any method known in the art for producing expanded polymer particles.
According to one embodiment of the invention, an additive increasing the viscosity is added to the material of the TPU article. This may be done before or during melting of the TPU. Other additives may be added as well to the TPU, either before or during melting. The additive increasing the viscosity can be mixed with the TPU before injection molding, for example, by a dry blended masterbatch. Even the additive manufacture of the TPU article is also conceivable.
The additive increasing the viscosity can be a TPU, which contains in an embodiment isocyanate groups. The additive increasing the viscosity can be a crosslinking additive, one such example being X-Flex® V2909. Further examples for a suitable additive are Elastollan X-Flex®, X-Flex® V2905, all being obtainable from BASF. In further embodiments, the additive comprises an organosilicon compound or group.
The additive can be used in amounts of, for example, 1 to 15% by weight, 1 to 10% by weight, or 1 to 5% by weight, based on 100% by weight of the TPU material. In exemplary embodiments, the additive is used in amounts from 1 to 4% by weight, in particular 2 to 3% by weight, for example, 1% by weight, 2% by weight, 3% by weight, 4% by weight or 5% by weight, based on 100% by weight of the TPU material.
In another embodiment, the TPU material of the pre-manufactured article has been annealed. The annealing can be carried out in at least one annealing step, for example, one or two annealing steps. It is also possible, and in some cases advantages, to perform a multi-stage annealing process, wherein multiple annealing steps are performed and the temperature is increased with each annealing step. The annealing step(s) increase the melting onset temperature, in particular to such an extent that a deformation of the pre-manufactured TPU article is avoided, when the particles of the expanded TPU material and the pre-manufactured article are connected in step c.
The annealing can be carried out by techniques known in the art. For example, the pre-manufactured article can be annealed in a circulation oven, which permits adjusting of the desired temperatures and time periods. Preferably, the annealing increases the melting onset temperature to such an extent that undesirable deformation of the pre-manufactured TPU article is avoided or that there is essentially no deformation of the pre-manufactured TPU article. The annealing step can be carried out at a temperature in the range of from 100 to 150° C., in particular from 110 to 140° C., preferably from 120 to 140° C., more preferably from 120 to 130° C., or from 130 to 140° C. The annealing step can be carried out for a time period of from 2 to 20 hours, in particular from 3 to 19 hours, preferably from 5 to 17 hours, more preferably from 10 to 17 hours, most preferably from 15 to 17 hours.
As mentioned above, the present invention is particularly applicable for the manufacture of shoe soles and further outsoles or outsole elements, which are to be connected to a midsole made from particles of expanded eTPU. Such a shoe sole with an outsole element is exemplary shown in
