Description

1. Technical Field of the Invention

The present invention relates to a double knitted element, in particular a sports article, and a method for the production of such a double knitted element.

2. State of the art

There are various manufacturing processes to provide a mesh element with desired functional properties such as rigidity, extensibility, resilience or compression properties.

Stiffness in particular is typically achieved by plating a melted yarn together with a base yarn (e.g. polyester) or simply by blending melted yarns with the base yarn in the same yarn guide. Another way to achieve stiffness is provided by knitting thermoplastic polyurethane (TPU) yarns or knitting hybrid yarns that are a blend of polyester and fused yarns. In addition, stretchability, resilience, or compression properties are usually obtained by inserting covered elastic yarns, by plating or blending elastane yarns together with the base yarn (e.g. natural fiber, synthetic fiber, synthetic) directly into the yarn guide, or by knitting covered elastic yarns elastic yarns.

Tucked yarns are typically used on a single layer knit base, e.g. B. with fleece fabric. With these fabrics, the yarns are too thick for regular knitting and are therefore tucked into the fabric. Furthermore, an elastic yarn can be used as an interlining or even in a tuck float structure for knitting socks, but this use is only known for a single jersey or knit layer.

Thus, the present invention addresses various problems to be solved.

When using plating or blending to achieve stiffness, the melted yarn follows the same knitting sequence as the ground yarn. In addition, the amount of melted yarn is difficult to control because it depends on the knitting structure. Furthermore, if the fusible yarn is only needed on one side of the fabric, the knitting sequence must be altered accordingly, resulting in a different visual appearance or property of the fabric. When the fusible yarn is mixed with the ground yarn, it is impossible to control which of the two yarns appears on the surface of the fabric. Plating the fusible yarn can improve this shortcoming, but it is usually difficult or time consuming to set up on the knitting machine. In particular, plating tends to be difficult to adjust on the knitting machine.

When using elastic yarns to create stretch, recovery or compression as laid-in yarns, there is always a risk of the elastic yarn being pulled out as it is not bonded to the fabric. In particular, the laid-in yarn is just a long floating yarn within the double layer knit fabric.

It is therefore the object of the present invention to provide a knitted fabric and a corresponding production method in order to achieve improved functional properties of the knitted fabric. In particular, there is a need to create functional properties in the knitted fabric regardless of the knitting sequence, to avoid the possibility of the inserted threads being pulled out, to retain the appearance of the knitted fabric but to provide it with additional functional properties, and/or to add the melted yarn to targeted locations of the knitted fabric to activate.

US 2017/0029989 A1 refers to textile constructions formed with fusible filaments. In particular, the document is directed to a textile construct in which thermoplastic yarns or fibers are fused to form a fused film on one side or layer of the construct while maintaining another side or layer in a discrete knitted structure. The fused film can provide a membrane face or sheet that has desired properties, such as B. one or more of waterproofness, water resistance, wind resistance and breathability.

3. Summary of the Invention

The invention is defined by the independent claims.

According to a first aspect, the above object is achieved by a double-layer mesh element, in particular for a sporting item. The double layer mesh element includes a first layer comprising a first yarn, a second layer comprising a second yarn, and a third yarn at least partially disposed between the first and second layers, the third yarn being interlaced by a plurality of Fangstitch is attached to at least one of the first and second layer, wherein between two consecutive Fangsti There is at least one skipped stitch in the third yarn.

Generally, the third yarn is connected to the fabric through the darts. Compared to the tucked third yarn of the present invention, plier strands are free floating within the double layer fabric and could be removed from the knit by pulling.

The third yarn is independent of the main knit structure and does not affect it, but also improves the properties of the knitted fabric. In fact, the tuck stitches visible on the surface of one of the knitted layers are minimalistic so that they do not significantly affect the surface finish of that knitted layer. Furthermore, since the third yarn is sandwiched between the two layers, additional protection of the third yarn is also provided. This means that yarns that would fail tests (abrasion, color migration, etc.) can still be tucked in and add function to a double layered mesh element.

The third yarn of the double knit element may comprise a functional yarn. The use of a functional yarn as the third yarn makes it possible to create functional properties in the knitted fabric independently of the knitting sequence.

The first yarn of the first layer and the second yarn of the second layer can be one and the same type of yarn, but they can also be two different types of yarn.

The functional yarn can be at least one of the following yarns: melted yarn, thermoplastic polyurethane (TPU) yarn, water-repellent yarn, bulky/bulky yarn, natural fiber yarn (e.g. wool and cotton), cellulose yarn, hybrid yarn, antimicrobial (antibacterial) yarn such as copper, zinc, silver, elastic yarn, conductive yarn, or at least one yarn with at least one of heat resistance, UV protection, heat retention, moisture absorption, water resistance, chemical resistance, flame resistance, moisture wicking, or at least one yarn with a compression, shrinkability , Damping, conductivity, insulation, durability property.

Advantageously, by using a functional yarn as the third yarn, the double-layer mesh element can be provided with different properties, depending on the functionality of the yarn. So e.g. B. the stretch, recovery or compression properties of the double-layer mesh element can be influenced by using an elastic yarn as a functional yarn. On the other hand, the rigidity can be achieved by using melted yarn, TPU yarn or hybrid yarn as functional yarn. So e.g. For example, melting or TPU functional yarns can be used to stiffen the heel and toe cap area of an upper, while elastic functional yarns can be used to stretch or reset the instep area or the collar of a fabric. In general, the use of elastomeric material creates reinforced areas after exposure to heat.

Another advantage is that the use of plating or blending of the functional yarn with the ground yarn in the yarn guide or the use of laid-in functional yarns is not necessary.

The third yarn can only be attached to one of the two layers by means of tuck stitches in the respective layer.

If the third yarn is only attached to one of the first or second layers by tuck stitches, the third yarn will not be visible on the other layer. This preserves the appearance of the top of one layer while providing the desired performance characteristics through the third yarn. In addition, the tuck stitches visible on the surface of one of the knitted layers are minimal so that they do not significantly affect the surface finish of that knitted layer. In fact, the third yarn is more or less independent of and does not affect the main knit structure. Rather, the tuck stitches visible on the surface of one of the knit layers are minimal in that they do not significantly affect the finish of that knit layer while at the same time leaving the finish of the other knit layer completely unaffected.

In addition, if a melted yarn is provided between the first and second layers and attached to only one layer, it is possible to activate the melted yarn only on the inside of one of the two layers. For example, when the fusible yarn is bonded (tucked) to the backsheet, after thermal activation, the fusible yarn is mainly absorbed by the backsheet, however, the outside of the front sheet may not show traces of the fusible yarn. This allows further post-processing to be carried out on the upper side of the fabric without using or reactivating the melted yarn.

The third yarn may be attached to at least one of the first and second layers by back-to-back tuck stitches.

A ratio between the number of tuck stitches and the number of missed stitches can be variable within a course or a row.

In particular, the support in a certain area of the double-layered stitch element can be determined by the ratio of tuck to skipped stitches. The more darts are close together, the more yarn is fed into that area. By varying the tuck-to-skip ratio of the third yarn in different areas, different stretch or stiffness properties can be achieved. In contrast, a liner strand would have the same property along its width.

The ratio between the number of tuck stitches and the number of skipped stitches can be at least one of 1:1, 1:2 or 1:3. A skipped stitch means that a needle in the needle bed is skipped and the third yarn is free-floating between two tuck stitches over this one needle. A catch to skipped stitch ratio of e.g. B. 1:2 means that two needles are skipped and the third yarn is free-floating between two tuck stitches over those two needles.

In general, the support of a double-layered stitch element can be influenced by the catch-to-skip ratio. The more darts are close together, the higher the proportion of the third yarn. For example, a catch-to-skip ratio of 1:1 provides more support than 1:2, with 1:2 providing more support than 1:3, and so on.

The distance between two consecutive tuck stitches can be less than 1 inch.

In general, 2.54 cm of the needle bed of a knitting machine corresponds to 14 needles on a 14 gauge machine or 7 needles on a 7 gauge machine, where the gauge of a knitting machine corresponds to the number of needles in 2.54 cm (one inch). For safety reasons, the floating yarns are usually kept shorter than 2.54 cm. If the floating yarns are longer, there is a risk that the needles will not catch the yarn.

The first yarn of the first layer can be attached to the second layer and/or the second yarn of the second layer can be attached to the first layer by tuck or loop stitches.

The third yarn can be knit at least twice between two rows of stitches. In other words, at least two courses of the third yarn are knit between two courses.

In this way, increased support can be achieved by maintaining the same tuck-to-skip ratio, but knitting the third yarn multiple times between two rows. Multiple knitting of the third yarn between two rows of stitches can e.g. B. can be used to increase the stiffness in a certain area of a fabric (e.g. in the heel of an upper).

The third yarn can be knit partially between two rows of stitches.

Partial knitting allows the third yarn to be provided in different amounts in different areas of the double-layer stitch element. Especially when the third yarn is partially knitted multiple times between two rows of stitches. Thus, depending on the amount of third yarn, different levels of support can be provided in different areas. In this way support of a particular area or zone can be developed by maintaining the same tuck-to-skip ratio but by partially knitting the third yarn one or more times in a particular area.

Also, partial knitting of the third yarn is technically simpler than an inlaid strand. This is because the third yarn is tucked into the fabric and does not pop out when the knitting direction is changed.

The thickness of the third yarn can vary within the knitted element.

Varying the thickness of the third yarn can also affect the support of the double layer mesh element.

The third yarn can be provided in repeating structures, jacquard structures, or in spacer-based structures.

Thus, structures such as repeating structures, jacquard structures or structures based on spacers can be developed using a functional yarn, with the appearance of at least one layer of the structures remaining the same.

The element can be made by inlay, interlock, plating, reverse plating, and/or inlaid techniques.

Thus, various double-layer elements with different structures and functional properties can be provided by the present invention.

A further aspect of the present invention relates to an upper for a shoe, in particular a sports shoe, comprising a double-layer mesh element as described herein.

A further aspect of the present invention relates to a shoe, in particular a sports shoe, comprising an upper as described herein, i.e. with a knitted element according to the invention, and a sole attached to the upper.

Thus, an upper or a shoe is provided that includes the advantageous properties of the double-layered mesh element described above.

According to a further aspect of the invention there is provided a method of making a double layer mesh element according to any of the preceding aspects. In particular, the method comprises the steps of providing a first layer comprising a first yarn, providing a second layer comprising a second yarn, and arranging a third yarn at least partially between the first and second layers, the third yarn being separated by a plurality of tuck stitches is attached to at least one of the first and second layers, there being at least one skipped stitch between two consecutive tuck stitches of the third yarn.

5. Detailed Description of Preferred Embodiments

Embodiments and variants of the present invention are described in more detail below using a double-layered mesh element, in particular for a sports item. However, the present invention can also be used in other ways, e.g.

The use of a third tuck-in yarn allows a double knitted element to have the desired performance characteristics without sacrificing the outward appearance. The various functional properties include e.g. B. stiffness, elasticity, extensibility, resilience or compression. The techniques used to achieve such properties or functions are described below.

The techniques described include appropriate knitting techniques that are different Combinations of the number of tucks and skipped stitches of the third yarn as well as the selection of fibers and yarns. These and other techniques are explained below before describing embodiments of shoe uppers using these techniques.

1A-C show knitting schemes of a double-layer stitch structure, with the dots representing the needle positions of a knitting machine in a knitting course. In particular, the knitting schemes of the 1A-C two rows of needles provided within a row.

1A Figure 1 shows a first layer 100 (e.g. the front layer) comprising a first yarn 110, a second layer 200 (e.g. the back layer) comprising a second yarn 210, and a third yarn 310 at least partially sandwiched between the first layer 100 and the second layer 200, the third yarn 310 being attached to the second layer 200 by a plurality of tuck stitches 311. In alternative embodiments, the third yarn 310 may be attached to the first layer 100 by a plurality of tuck stitches. As in 1A shown, there is at least one skipped stitch 312 between two consecutive tuck stitches 311 of the third yarn. In this embodiment, the ratio between the number of tuck stitches and the number of skipped stitches, which corresponds to the catch to skipped stitch ratio, is 1:1.

In general, the main double-layer knit structure is independent of the tuck-in yarn. The tuck-in yarn is an addition to the existing structure and is inserted between the two layers.

Furthermore shows 1A that the third yarn 310 is attached to the second layer 200 only by consecutive tuck stitches 311, the third yarn 310 not being attached to the first layer 100.

In a specific embodiment, when using fusible or TPU yarns as the third yarn 310, the stiffness can only be transferred to one of the two layers.

In another embodiment, the stiffness is achieved within the fabric without detracting from its external appearance.

In one embodiment of the invention, the first 110 and second 210 yarns may be different.

In another embodiment, the first 110 and second 210 yarns may be the same.

in the in 1A illustrated embodiment, the first layer 100 is connected to the second layer 200 by tuck stitches.

1B FIG. 12 shows a portion of a front layer 100 of an exemplary double-layer stitch element comprising a first yarn 110, wherein 1C shows a detail of a rear layer 200 comprising a second yarn 210. FIG. In the 1B and 1C a melted yarn 310 is bonded (tucked) to the back sheet 200 . In particular, after thermal activation, the fusible yarn 310 is largely absorbed by the backsheet 200 (a little also by the inside of the frontsheet 100). There is no melted yarn 310 on the outside of the front layer 100, as in FIG 1B shown. Thus, further post-processing can be done on the face of the fabric without using or reactivating the fusible yarn 310 underneath the front layer 100 . As in the example of 1C As shown, the first yarn 110 of the front layer 100 may be attached to the back layer 200 by tuck stitches or loop stitches.

Generally, the third yarn is connected to the fabric through the darts. Compared to the tucked third yarn of the present invention, liner strands would float freely within the double layer fabric and could be removed from the knit by pulling.

Furthermore, in various embodiments of the present invention, the third yarn may comprise a functional yarn.

In some embodiments, the functional yarn can be at least one of the following: melted yarn, thermoplastic polyurethane (TPU) yarn, water-repellent yarn, bulky / bulky yarn, natural fiber yarn (e.g., wool and cotton), cellulosic yarn, hybrid yarn, antimicrobial (antibacterial) yarn such as copper, zinc , silver, elastic yarn, conductive yarn, or at least one yarn with at least one of the properties of heat resistance, UV protection, heat retention, moisture absorption, water resistance, chemical resistance, flame resistance, moisture wicking, or at least one yarn with a compression, shrinkage, cushioning , Conductivity, insulation, durability property.

Applications for knitting a conductive yarn could be, in particular, to heat certain parts of the upper or to transfer electricity to LED lights in the upper or tool, with wool yarns heating the upper and cotton yarns can absorb moisture.

2 shows an exemplary embodiment, in which the third yarn 310a can be inserted into the first layer 100, i.e. onto the front stitches of the row 110, in a first knitting step, and the third yarn 310b can be inserted into the second layer 200 in a second knitting step by means of immediately consecutive tuck stitches , ie can be inserted into the back stitches of the preceding row 210, not shown here.

3A and 3B show knitting schemes with different ratios between the number of tuck stitches and the number of skipped stitches of the third yarn 310.

As in 3A shown, there are two skipped stitches 312 between two consecutive tuck stitches 311 of the third yarn 310, the ratio between the number of tuck stitches 311 and the number of skipped stitches 312 being 1:2. 3B shows a knitting scheme with three missed stitches 312 between two consecutive tuck stitches 311 of the third yarn 310, the ratio between the number of tuck stitches 311 and the number of missed stitches 312 being 1:3.

In general, the support (in terms of stiffness or stretch properties) of a double-layered stitch element can be engineered by the tuck-to-skip ratio. The more darts are close together, the higher the proportion of the third yarn 310. For example, a catch-to-skip ratio of 1:1 provides more support than 1:2, with 1:2 providing more support compared to 1 :3 offers and so on.

In a specific embodiment, not shown herein, the distance between two consecutive tuck stitches can be less than 2.54 cm (one inch). In particular, 2.54 cm of a needle bed of a knitting machine corresponds to 14 needles on a 14 gauge machine or 7 needles on a 7 gauge machine, where the gauge of a knitting machine corresponds to the number of needles in 2.54 cm, which corresponds to 1 inch. For safety reasons, the floating yarns are usually kept shorter than 2.54 cm. If the floating yarns are longer, there is a risk that the needles will not catch the yarn.

Furthermore, the 3A and 3B Examples where the first layer 100 is connected to the second layer 200 by loop stitches. In the embodiments of 3A and 3B the third yarn 310 is attached to the second layer 200 only by directly consecutive tuck stitches 311, i.e. there are no tuck stitches of the third yarn 310 in the first layer 100.

In other embodiments, the third yarn is attached to at least one of the first and second layers by tuck stitches. For example, the third yarn 310 can be tucked in on the first layer 100 and the second layer 200 . In other embodiments, the third yarn may be tucked in only on the first layer by back-to-back tuck stitches.

4 Figure 12 shows another embodiment where the third yarn 310 is knitted at least twice between two courses. In this embodiment, at least two courses of the third yarn 310 are knit between two courses. In particular, the third yarn 310 is knitted in a first knitting sequence 301 (eg, right yarn over) and in a second knitting sequence 302 (left yarn over), thereby increasing the support of the third yarn 310 on the double layer stitch element.

Repeated knitting of the third yarn 310 between two courses can z. B. be used to increase the stiffness of a substance.

The level of support can also be engineered by using finer or thicker yarns (150 denier to 900 denier). Even 2,000 deniers are possible for a melted yarn and even more for knitted socks. Above all, higher deniers mean thicker yarns.

4 12 shows an example where the first sheet 100 is attached to the second sheet 200 by loop stitches.

In the embodiment of 4 the third yarn 310 is only attached to the second layer 200 by consecutive tuck stitches 311 and not to the first layer.

In another embodiment that is not explicitly shown here, the third yarn 310 can only be tucked in on the first layer 100 or can be tucked in with tuck stitches on the first layer 100 and the second layer 200 .

In general, the third yarn is independent of and can be combined with all double knit structures. This means the structure can remain the same, but the function (stretch/stiffness/conductive yarn) is applied at different points on the bodice.

In some embodiments, the third yarn can be in repeating structures, such as in 1-4 shown, or in jacquard structures, as in 5 shown to be used.

In other embodiments, the laid-in third yarn may be combined with knitting techniques such as partial knitting, intarsia (zone knitting), plating, reverse plating, devore, inlay, and so on.

Some additional knit structures using a functional yarn 310 are shown in FIGS 6A-C shown. 6C shows e.g. B. an interlock structure with a third yarn.

In other embodiments, the third yarn can also be used in spacer-based structures, as in 7 shown. In 7 a spacer layer 400 and the third yarn 310 are knitted alternately between two rows of stitches of the first layer 100 and the second layer 200.

8th FIG. 12 shows an embodiment of the invention in which the ratio between the number of tuck stitches and the number of skipped stitches is variable within a course or a row. In particular, the degree of support in different sections (510, 520) within the same course of the stitch element can be developed by the tuck-to-skip ratio. In particular, the example shows 8th a first section (510) with a tuck-to-skip ratio of 1:3 and a second section (520) with a tuck-to-skip ratio of 1:1. The more darts that are close together, the more yarn will be added in that particular section.

Varying the tuck-to-skip ratio of the third yarn in different areas can provide different stretch or stiffness properties in the respective areas. In contrast, a lay-in strand has the same property along its width.

In some embodiments, the ratio between the number of tuck stitches and the number of missed stitches can be at least one of 1:1, 1:2, or 1:3.

9 Fig. 12 shows an embodiment wherein the third yarn 310 is partially knitted in a certain portion of a course. In 9 the third yarn 310 is provided once in a first section 530, with the third yarn being provided multiple times (eg three times) in another section 540.

Partial knitting of the third yarn, as in 9 As shown, can provide different support by maintaining the same tuck-to-skip ratio, but knitting different amounts of the third yarn 310 in a particular portion of the knit course or region of the double layer stitch element.

In addition, partial knitting of the third yarn is technically easier compared to an inlaid strand. The reason for this is that the third yarn is connected to the fabric and it doesn't pop out when the knitting direction is changed.

10A-B Figure 12 shows an embodiment with efficient placement of a third yarn 310 in a double knit element using intarsia knits. In general, intarsia can be used to develop special zones on the knitted element that have special properties. In the specific embodiment of 10A For example, in a portion of the knitted element between the front 100 and back layers 200, the third yarn 310 is knitted multiple times in consecutive courses in a double jersey knit. In addition, the third yarn 310 is attached to the first 100 and second 200 plies by alternate tuck stitches.

In a specific embodiment, a third yarn 310 can be used with an elastomeric material to create reinforced areas after heat exposure. In addition to elastomer, other polymer-based yarns can also be used that produce a reinforcing effect when heat, pressure or other treatments are applied.

Furthermore, due to the knitting method, no pre-twisting of the materials is required and manual labor is reduced, and high-performance bodice materials can be produced.

10B Figure 12 shows a detail of a double knit element using intarsia knits in a double jersey knit with the third yarn 310 attached to the first 100 and second layer 200 by alternate tuck and miss stitches. By using tuck stitches of the third yarn 310 on both layers, the third yarn 310 is visible in both layers (e.g. first layer 100 of 10B) .

In a further embodiment, an upper for a shoe, in particular a sports shoe, can be provided which comprises a double-layer mesh element according to the present invention.

Furthermore, a shoe, in particular a sports shoe, can comprise an upper comprising a double-layered mesh element according to the present invention and a sole attached to the upper.

11 Figure 13 is a flow chart illustrating a method of making a double layer mesh element in accordance with the present invention and as described in more detail above. In step 1110, a first layer comprising a first yarn is provided. In step 1120, a second layer comprising a second yarn is provided. In step 1130, a third yarn is placed at least partially between the first and second layers, the third yarn being attached to at least one of the first and second layers by a plurality of tuck stitches, there being at least one skipped stitch between two consecutive tuck stitches of the third yarn gives.
