Patent Application
20180132487
This application is related to and claims priority benefits from German Patent Application No. DE 10 2016 222 480.8, filed on Nov. 16, 2016, entitled APPAREL OR SHOE COMPRISING SPIDER SILK (“the '480.8 application”). The '480.8 application is hereby incorporated herein in its entirety by this reference.
The present invention relates to an article of wear, which may be an apparel or shoe, comprising spider silk.
Apparel or shoes tend to develop smells because of the development of skin fungi. This is especially true for apparel or shoes made to a large extent from synthetic materials due to the structure of the fibers used. The problem is aggravated with sports apparel or shoes which are subject to sweat when wearing the apparel or shoe during sports activities.
Antibacterial materials such as silver may mitigate the above-mentioned problem. However, some bacteria are beneficial to the human body and even necessary to maintain a healthy skin flora. Therefore, such antibacterial materials may cause more harm than benefit because they tend to kill useful bacteria as well.
According to U.S. Pat. No. 7,587,841 B2, a shoe is provided with an ankle support member to reduce the risk of ankle injury. The ankle support member is a stiff resilient piece of bendable sheet material including a base portion, and a plurality of lateral and medial strips which are inclined upwards and backwards. The ankle support member is bound together with artificial spider web silk for additional strength and flexibility. However, this document neither mentions the technical problem mentioned above nor provides a solution.
It is therefore the objective of the present invention to provide an article of wear, which overcomes or at least reduces the problem of odor formation, in particular with an apparel or shoe for sports applications.
The terms “invention,” “the invention,” “this invention” and “the present invention” used in this patent are intended to refer broadly to all of the subject matter of this patent and the patent claims below.

According to certain embodiments of the present invention, a method of manufacturing a article of wear comprising: forming an inner surface of the article of wear; and forming an area of the inner surface with spider silk.
In the following detailed description, embodiments of the invention are described referring to the following figures:
The objective mentioned above is met by an article of wear, which may be apparel or shoes, comprising an inner surface, wherein the inner surface comprises an area comprising spider silk.
An inner surface in the context of the present invention is understood as a surface adapted to face a wearer's skin.
Spider silk in the context of the present invention is understood as any natural or synthetic material comprising spider silk or spider silk-like proteins. Thus, spider silk in the context of the present invention may either be produced by spiders or synthetic processes which aim to synthesize the properties of natural spider silk. Suitable methods to obtain synthetic spider silk yarns or threads are, for example, described in WO2014037453 A1, U.S. Pat. No. 7,868,146, U.S. Pat. No. 8,097,583, U.S. Pat. No. 8,372,436 and EP2547810 A1.
The inventors of the present invention have found that providing an inner surface of an article of wear with spider silk may reduce the formation of odor, especially for sports apparel or shoes. This is due to the antibacterial effect of spider silk. At the same time, spider silk does not kill all bacteria which populates human skin and helps to maintain a base population of those bacteria which are beneficial to the skin flora. Furthermore, due to its excellent tensile strength, spider silk is able to withstand the forces which are caused by movements of the wearer. This aspect is especially important for sports apparel or shoes. Furthermore, spider silk has a high degree of abrasion resistance. Such resistance may be explained by its filaments having a high tensile strength, such that more force is required to break the filaments. Hence, spider silk is able to fulfill its odor reducing effect over a long period of time.
According to the invention, the spider silk is located in an area of an inner surface of an article of wear. An inner surface of the article of wear is understood as a surface that is adapted to face a wearer's skin when the article of wear is worn in contrast to an outer surface, which would not face a wearer's skin, when the article of wear is worn. This does not necessarily mean that the spider silk directly contacts a wearer's skin. For example, in the case of an apparel such as a tracksuit, sports jacket, shorts, etc. the wearer may wear underwear or another garment, such that the spider silk comes into contact with the underwear or the other garment. In the case of a shoe, the wearer may wear socks, such that the spider silk comes into contact with the socks.
In certain embodiments of the present invention, the spider silk comes in direct contact with the wearer's skin. For example, in case of an apparel, such as underwear, a jersey, a swim suit, a t-shirt, etc., the spider silk may be located at an inner surface of such apparel and may directly contact the wearer's skin. In the case of shoes, the shoes may be worn without socks, which is the case with sprinting shoes, and the spider silk may directly contact the wearer's skin. Thus, the spider silk may be arranged in the article of wear according to the invention to contact the skin of a wearer when the article of wear is worn.
Furthermore, in the case of shoes, the area of the inner surface comprising spider silk may be located at the shoe upper, the insole or both. Generally, the area comprising spider silk may be located at specific locations and may be used to locally increase the strength while having a high resistance (high elongation before break).
Furthermore, spider silk is a material which is strong and has a high elongation before breakage but is also easy to color because it is protein-based. Additionally, spider silk has a high UV-resistance. Other elastic fibers in the industry are not easy to color, such as the Dyneema® fibers, and/or are not resistant to UV, such as Kevlar®.
Furthermore, spider silk is highly moisture absorbent. It can therefore be used in applications where sweat management and/or a cooling effect is sought, be it in apparel or shoes. The spider silk may provide such functions in combination with its other characteristics described herein.
A second area of the shoe or textile may be water repellent. Thus, the area with the spider silk could provide a bacteriostatic and moisture absorbent effect, while the second area could prevent or at least reduce moisture from entering the shoe or apparel. Thus the moisture of the article of wear, and more particularly the sweat of the wearer, may be better managed. In some embodiments it may help to guide and better evaporate sweat. The second water repellent area may overlap at least partially the first area comprising spider silk. Thus, different functions would form in different layers of the article of wear. Besides, a first yarn comprising spider silk may be woven or knit together with a water repellent yarn. In this way, the moisture absorption level may be varied in different areas of the article of wear, for example by varying a proportion of the first yarn.
The mentioned area may comprise a first yarn comprising spider silk. For example, this yarn may be embroidered on a base layer such as leather. In other embodiments, the first yarn may be used to form a textile placed in said area.
At least a portion of the inner surface of the article of wear according to the invention may be formed by a first textile comprising the area. The first textile may comprise a first yarn comprising spider silk. The textile may be formed of 100% spider silk yarn, or may only contain a percentage inferior to 100% and be combined with yarns of different material, whether natural, synthetic or biomimetic. For example spider silk yarns may be used in a knit textile in combination with polyester yarns.
In particular, the textile may be formed of 30% to 100% spider silk, more particularly of 40% to 100% spider silk. Generally, the amount of spider silk may depend on the particular application and may be 50% to 100% when close to a wearer's skin and 10% to 75% for tenacity purposes when farther away from the skin, for example between 10% and 65% for an outer layer of an article of wear.
The spider silk textile may be formed by weaving, knitting, embroidering yarns of spider silk together or with other yarns of different materials, or forming a non-woven textile with fibers of spider silk.
The spider silk yarn may also be embroidered on a base layer. A base layer may be of any material, for example textile, leather, non-woven, polymer sheet, etc. In some embodiments of the invention, the spider silk yarn may be embroidered in specific locations of the article of wear.
The spider silk yarn may be used in a conventional knitting machine with no or very few adjustments and be knitted together with yarns of other materials. In particular, there is no need to change the parameters of the machine to account for the high strength/elasticity of the material. Thus, only small adjustments to the machine are needed, such as speed of the machine and yarn tension. This is different from other fibers such as Kevlar® or Dyneema® that cannot be knit. Due to the high elongation before breakage, a knitting pattern may be used that puts a high tension on the yarn. This allows creating stiff knit textiles that may be integrated in shoe uppers to provide good support such as in lateral support in lateral sports. Also, a textile comprising spider silk according to the invention may comprise spider silk yarns of different deniers and/or thickness (diameter). The yarns may also have different cross-section shapes.
Generally, a spider silk yarn or thread may be used in a textile in particular for a piece of apparel or a shoe, with an increased elasticity and a high strength. In particular, it has a very high elongation at breakage while maintaining its strength. Spider silk is very strong and very elastic compared to Dyneema® and Kevlar®.
The first textile may have been shrunk by exposing it to water before it has been incorporated into the article of wear. A spider silk textile (in particular knit) may shrink with a high shrinkage ratio when first exposed to water. Thereby a very stiff knit textile may be obtained whereby the spider silk is first knitted into a knit textile which is then made to shrink.
The invention also envisions a method of manufacturing an article of wear, which may be a piece of apparel or shoe, in which: (a.) a textile is knitted with at least one yarn comprising spider silk, and (b.) the textile is shrunk. The textile may be shrunk by contact with liquid water or steam. The result is a very stiff knit textile with very small sizes of knit loops. The knit loops “lock” to form a high stiffness knit. That can, for example, be beneficial in a sprinting shoe which needs to be stiff and tight on the foot, while being worn with bare feet. Due to the usage of spider silk according to the invention, the inner surface of the sprinting shoe is both bacteriostatic and provides for a comfortable skin feel.
The textile may be shrunk and then used to create the piece of apparel or shoe (in particular a shoe upper). Thus, according to this first alternative, spider silk yarn (e.g. the first yarn) is used to form a textile (e.g. the first textile), for example by knitting. Then, the textile is shrunk before using it to form the finished product (e.g. an apparel or shoe). For example, in the case of a shoe, the shoe upper is cut in the textile and then used to form the shoe. Alternatively or additionally, at least one layer of the insole may be cut from the spider silk textile with this layer being placed on the top portion of the insole (facing the inside of the shoe).
Alternatively or in combination to the above option, the first yarn may be exposed to water before being used to form a textile. In some embodiments, the yarn may have been shrunk before it is used to form the first textile. In this case, the pre-shrunk spider silk yarn is used to form the first textile which results in a very stiff and durable textile. This technique may be combined with the above technique, i.e. the finished textile may additionally be exposed to water before it is used to manufacture the article of wear. The first yarn may have been shrunk by having it run through a water bath.
Alternatively or in combination the textile may be used to create the piece of apparel or shoe and then shrunk to size—for example a shoe upper may be formed and then shrunk while placed on a last. In some embodiments, a textile may be partially shrunk before being used to form a piece of apparel or shoe, and then be subjected to an additional shrinkage after the piece of apparel or shoe is formed.
In some embodiments however, neither the spider silk yarn nor the textile is shrunk before it is incorporated into the article of wear, but the semi-finished article of wear is exposed to steam and/or water. In this case, the final size (after shrinkage) must of course be considered to obtain an apparel or shoe with the desired size. By this technique, a (partially) stiff and durable article of wear may be obtained.
Since spider silk shrinks mainly when first subjected to steam and/or water, the mentioned options of pre-shrinking the spider silk guarantee that the spider silk in the final product (e.g. an apparel or shoe) will not shrink anymore. In particular, the article of wear comprising spider silk may be exposed to steam. More particularly, a shoe upper may be exposed to steam while on a last. The inventors have found that the shrinking process may be better controlled when using steam instead of water.
The first yarn may comprise essentially only spider silk. Thus, the first textile may comprise essentially only spider silk as well if entirely made from the first yarn. However, in some embodiments, the first textile is manufactured from the first yarn and a second yarn comprising a different material than spider silk. Thus, by mixing spider silk with at least one different material either in the first yarn or by using two different yarns, the properties of the first textile may be tuned. Furthermore, less spider silk is needed compared to forming a textile with pure spider silk yarns.
Generally, a spider silk yarn and a yarn of a different material may be used together to form the area (for example they cross each other in a woven or knit textile). However, in other embodiments, a first area of the textile may comprise the spider silk yarn and a second area of the textile may comprise the yarn of a different material.
When mixing spider silk in the first yarn with another material, the other material may be a natural, synthetic or biomimetic component. Mixing may be achieved by co-extruding or coating for example. Alternatively, fibers may be twisted or mingled, or staple fibers of multiple materials may be combined in a blended staple yarn. A spider silk may for example be applied as a coating on a yarn of a different material, or as wrapping yarns around a yarn of a different material. In an example, the first yarn may comprise spider silk and at least one plastic material. The plastic material may provide an additional function to the yarn and, thus, to the first textile. Examples of such functions are insulation, moisture wicking, water-repellency, additional abrasion resistance, additional stiffness and stability, meltability, color, etc.
The first textile may comprise a second yarn made from a different material than spider silk. In this way, the textile may be provided with an additional function. While the spider silk yarn provides for a bacteriostatic effect, the second yarn may, for example, be moisture wicking to transport sweat away from the skin. The second yarn may, for example, be made from plastic, such as polyester.
The first yarn may be texturized. In this way, the yarn may, for example, be “bulked”. This improves the haptic of the yarn by making it softer. Also, such process gives the yarn different mechanical properties. It may in particular improve the yam's heat resistance, specifically heat created by abrasion or friction with another textile. Also, such yarn may be more insulating as it encloses more air pockets. Such bulking may be obtained by submitting the yarn to air-jet while being formed.
The first textile may be a knit, woven or non-woven. These types of textiles can cost-efficiently be manufactured on appropriate machines. Due to the properties of spider silk, only very few adjustments are needed to process the spider silk.
Also, the spider silk may be added afterwards to the textile, through embroidery or coating for example. The area of the inner surface may comprise a coating comprising spider silk. Thus, the apparel or shoe (such as the shoe upper or insole) may be coated with spider silk proteins so as to benefit from the characteristics of the spider silk, in particular the bacteriostatic effect and comfortable skin feel, at a low cost of production because less spider silk is needed compared to forming a textile with spider silk yarns. Examples of coating may be found in WO 2011069643, which relates to a method for coating an inert or naturally occurring material with a silk polypeptide.
The coating may be a foam, a gel or a non-woven. Examples of how to apply a coating as a foam, gel or non-woven may be found in EP 2615102.
The inner surface may be a portion of an inner lining of the article of wear. In particular, the article of wear (such as the shoe upper and/or the insole) according to the invention may comprise at least one layer comprising spider silk. The benefits of using spider silk for a lining of an apparel or of a shoe upper or insole are that the spider silk is very comfortable and offers a particularly good skin feeling. It is also biocompatible and therefore is non-allergenic, such that the skin is not irritated when the lining comes into direct contact with the skin. It may also be desirable in recovery shoes or apparel as it is a material that is particularly respectful and soft on the skin and the wounds.
As already mentioned, bacteria develop less in textiles including spider silk than in other textiles as spider silk is anti-fouling (bacteriostatic). Therefore, the use of a lining including spider silk in a piece of apparel or in a shoe is particularly beneficial to limit the development of smells due to bacteria or the development of skin fungi. That could reduce in particular the bad odor that is absorbed by clothes when sweating. The spider silk could be used in shoes to be worn with bare foot, insoles, and particular areas of a piece of apparel such as e.g. the arm pits.
The article of wear may further comprise an outer surface comprising spider silk. Spider silk has a very high strength and abrasion resistance and can therefore form the outer layer of a shoe or of a piece of apparel. It may in particular be used in combination with a comfort inner layer as described above.
In some embodiments, at least one area of the piece of apparel or shoe upper comprises only one layer comprising spider silk. Thereby this sole layer forms both the inner surface and outer surface of the piece of apparel or shoe upper.
Alternatively, at least a portion of the outer surface may be formed by a second textile comprising spider silk. The second textile may comprise a third yarn comprising spider silk. In each case, the desirable properties of spider silk would be present on both sides of the article of wear. While on the inside, the bacteriostatic effect would be most important, spider silk on the outside would add to the stiffness, stability and abrasion resistance.
The second textile may comprise a different knit structure and/or yarn structure compared to the first textile. While the knit and/or yarn structure on the inner surface could provide for a comfortable feel, the knit and/or yarn structure on the outer surface could provide for stability, abrasion resistance, etc. In some embodiments, the first yarn used for the first textile on the inner surface is textured as described above. In some embodiments the first textile comprises small knit stitches and the second textile comprises large openings (for example obtained by miss stitches when knitted). The first textile may be placed on the inner surface and the second textile may be placed on the outer surface.
The article of wear may further comprise a plurality of layers comprising spider silk. Besides, at least one layer may be successively peelable. This could provide the possibility to change the aesthetics of a wearable article. It could also avoid having to clean the wearable article when it is dirty. It could also be desirable to have an article looking as if new when the outer layer is removed. It may also improve the hygiene, for example when an internal layer is dirty. Peelable layers may be used for internal surfaces of a piece of apparel or shoe upper, such as a lining for example. It may also be used for external surfaces of a piece of apparel or shoe upper. If it is realized with peelable layers made of biodegradable layers for example including spider silk, the environmental footprint of such products would also remain very low. Such peelable layers may be cut by the wearer or torn along lines of engineered weaknesses in the layer.
The shoe described so far may comprise a shoe upper, wherein the inner surface is a portion of the shoe upper. This can prevent or at least decrease the formation of odor in the shoe thanks to the bacteriostatic properties of spider silk.
The shoe may further comprise a sole structure, wherein the sole structure is separable from the shoe upper. Thus, the area comprising spider silk may be arranged at an inner surface of the shoe upper and the shoe upper may be removed from the sole structure and is biodegradable due to the spider silk. The sole is usually durable and may be used with different or new shoe uppers comprising spider silk. Thereby, the lifetime of the sole may be increased. Indeed, nowadays some wearers often change their shoes because they want to change its aesthetics, and/or because the upper is deteriorated and/or because it is dirty. Since the spider silk is fully biodegradable (it is protein-based) a textile upper made of spider silk has a very low ecological foot print. This applies to a shoe with interchangeable uppers comprising spider silk yarns as well. In the same way, a piece of apparel could comprise an interchangeable layer comprising spider silk yarns. This would make a very sustainable shoe and/or piece of apparel since the durable portions are kept, and the renewed portions are biodegradable.
In case of a piece of apparel the area comprising spider silk may be arranged in an armpit region of the apparel. In this region strength and flexibility is required, as well as moisture absorption and bacteriostatic properties, in particular in some sports such as tennis (service movement). It may also be used in gloves to ensure good protection, and at the same time flexibility and moisture management.
A further aspect of the present invention relates to a method of manufacturing an article of wear as described above, comprising the steps of providing an inner surface of the article of wear, such that it is adapted to face a wearer's skin, and of providing an area of the inner surface with spider silk.
The spider silk used in the context of the present invention may be made sensitive to some specific chemical agent in order to react in a given way to this chemical agent. For example, it may be made to be dissolvable in this specific chemical agent or chemical family. A product containing such spider silk could thus be easily recycled or disposed of in an ecological manner since the spider silk is protein based.
Spider silk in the context of the present invention may be used in a non-woven yarn to form a non-woven textile that may be used in pieces of apparels or shoes in replacement of textiles, or as cushioning pads. Electrospinning may be used to prepare a non-woven yarn comprising spider silk. Such non-woven yarn may also be used as a coating.
The spider silk's properties may be adjusted by modifying the properties of the proteins it is made of, in order to customize its physical and/or chemical properties. For example, it may be reactive to a specific chemical or chemicals family and be programmed to be dissolvable in such chemical, etc.
Generally, spider silk is a material which has a perfect balance between all these different technical functions required in the clothing and shoe industries, and in particular in the sports clothing and sports shoe industry. It is the only material which combines the different features described herein together. Therefore, a shoe upper or a piece of apparel may be formed with only one layer including spider silk, and at the same time exhibiting many functional features simultaneously.
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.
The sole structure 11 comprises an outsole 11a and spikes attached thereto. Three of those spikes are exemplarily denoted with the reference numeral 11b. Attached to the sole 11 is a shoe upper 12. In the example of

In the example of
The textile 13 was knitted in a 20% larger size and then lasted on a production last. In a next step, the upper was steamed in order to let the yarn shrink in a controlled way so that the shoe upper 12 will then ultimately conform to the size of the last. It should be noted that soaking the shoe upper 12 into water does not always allow sufficient control of the shrinkage.
Alternatively, the knitted textile 13 may be shrunk by exposing it to steam or water before it is incorporated into the shoe 10. Alternatively, the spider silk yarn of the textile 13 may have been shrunk by exposing it to steam or water such as having it run through a water bath before it is used to form the textile 13.
In the example of
Instead of mixing spider silk with another material in a yarn, the textile 13 may be created, for example, by weaving or knitting with some yarns made of spider silk, and some others made of other materials such as natural fiber based yarns (e.g. cotton, linen, etc.) and/or synthetic fibers (e.g. polyester, nylon, etc.).
In some embodiments, the spider silk yarn may be texturized to add bulk or prepare the yarn for further spinning processing and post processing as will be described with respect to
In the example of
The shoe 10 in the example of
In the example of
If an inner and outer textile is used for a shoe upper, the outer textile may comprise a different knit structure and/or yarn structure compared to the inner textile. Generally, an article of wear according to the invention may further comprise a plurality of layers comprising spider silk.
The textile 13 comprises a second area or portion 32 comprising the tongue and collar which does not comprise spider silk. However, in a variation of the embodiments, this second area 32 could comprise some amount of spider silk. It is important to note that the percentage of spider silk in the first area 31 is different than in the second area 32.
The second area 32 may comprise a mix of different yarns like for example polyester and elastane. The first portion 31 and the second portion 32 are knitted together.
Besides, as may be seen in
Furthermore, the shoe upper 12 comprises a webbing 34 to modify locally the elasticity of the shoe upper 12.
Then, the shoe upper 12 is put on a last 51 which is shown in
As mentioned above, the last 51 is shown in more detail in
It should be noted that the step of pre-shrinking the shoe upper 12 as described above is important because otherwise, the shoe upper 12 would be too big to be placed on the last.
The shrinking process as described above can also be applied to two-dimensional knitted shoe uppers. The difference is that no last is used as illustrated in
