Description

It is adapted to the footwear of foot

The application is entitled " footwear for being adapted to foot ", Application No. " 201410160424.4 ", the applying date For the divisional application of the application of " on 04 21st, 2014 ".

1st, technical field

The present invention relates to a kind of footwear, especially sport footwear.

2nd, prior art

Normally, footwear include sole and are fixed to the vamp of the sole.Sole and vamp are by leather in traditional footwear Into, it is typically what is be made up of synthetic material in sport footwear.

Footwear are that the vamp of footwear provides bigger stability than socks to foot with socks difference.Vamp is to foot Fixation is tighter than socks.In addition, the sole protection foot of footwear is from injury and provides buffering, i.e. the impact of sole absorbability, example Such as, during running.By using suitable material, such as rubber and/or die mould, the soles of footwear further provide for ground must Want static friction.Socks can not realize the above-mentioned functions of footwear.

In common footwear, the foot of the wearer of footwear is surround by vamp and sole completely, i.e. each toe of foot that This is adjacent.In addition, toe is placed on sole, so each toe contacts the sole as an entirety respectively.Single toe Individual contacts can not possibly be carried out by sole and ground.Toe can be moved to the inside of footwear simultaneously, and these toes are only as whole Body applying power on sole.

Such case is considered as adversely and unusual.Foot medical treatment viewpoint think to walk barefoot be it is preferable, its Middle toe can be free to move to maximum magnitude, and each toe directly contacts with ground and can experience ground.

However, only could comfortably be walked barefoot on the soft floor for not having danger.Even small stone It is recognized as uncomfortable and carrys out injured harm to foot strip, just as glass fragment.In addition, especially in winter, outdoor surfaces It is typically too cold for cosily walking barefoot.

On the one hand, when walking in order to which the wearer to footwear more naturally feels, similar to walking barefoot, the opposing party Face, protection foot is from injured and suffer from cold, it is known that footwear include especially part to accommodate toe.Each toe can move the portion Divide, herein part, toe is placed independently of other parts.This causes each toe individually to be contacted with ground and feels ground.From And, the comfortableness walked is similar to the sensation walked barefoot, but simultaneously, the sole protection foot of footwear is prevented injured and suffered from cold.

For example, US2007/0144039A1 is related to one piece of footwear, it is allowed to which one piece of wearer's toe of footwear is individually moved While provide comfortableness, protection and improve tactile feedback.

But, it has proved that the defect of this footwear is that the connection between different piece is considered as toe being not Comfortably.The part is typically to be stitched together or glued together, so, has between toe thick and is easy to experience Seam.This is considered as uncomfortable, it might even be possible to cause the space between toe to be worn.

The 154A1 of DE10 2,011 055 are related to a kind of socks for being used to cover foot, and use firm and cut-resistant yarn Line is used for socks.One piece of socks is set in the way of similar socks, around each toe and by the material of at least part cut resistant Composition.

The 165U1 of DE20 2,007 011 are related to one piece of a kind of footwear, are especially designed with socks or above-knee socks, substantially by least The above-knee socks element and sole element composition of part covering foot formation, above-knee socks and sole element are connected to each other to one Individual entirety.

The solution that the 154A1 of DE10 2,011 055 and the 165U1 of DE20 2,007 011 are provided be totally different from footwear or Vamp.As having already explained above, socks can not provide necessary stability to foot, especially in Sports Field.In addition, carrying The solution of confession lacks any buffering, and this is especially indispensable during running, with Saving cortilage from power Knotting influences.

Therefore it is an object of the invention to provide a kind of footwear, particularly sport footwear, assign a kind of similar with walking barefoot Feel on foot, while not causing between toe uncomfortable in space to feel.

3rd, the content of the invention

According to the first aspect of the invention, this problem is solved by the vamp of footwear, particularly the vamp of sport footwear, passes through footwear Comprising solving for accommodating multiple Part I of foot at least one toe, wherein Part I can be substantially independent each other Ground is moved, and wherein Part I includes braid.

Include the Part I for being used to accommodate each at least one toe of foot according to the vamp of the present invention.The Part I Can substantially independently it be moved to each other so that toe is free to move to particular range, i.e. pin in the case of as city shoe The movement of toe is unrestricted.So as to which in the case of being moved in the part, its adjacent part is due to rubbing on vamp and/or sole The transmission of power or power is wiped, can slightly be moved.

Because Part I can be moved essentially independently, toe can also be largely independent mobile each other.This production Give birth to similar to the sensation of walking naturally walked barefoot.Toe can be moved freely, and individually be contacted with ground, can be felt Ground.In addition, the grasping movement of toe is also possibly realized, this is indispensable in some type of sports of such as climbing.

5th, embodiment

Hereinafter, embodiments of the present invention and deformation by the vamp for footwear, particularly sport footwear specifically Ground is described.

The applicable product of the use of braid has：Such as vamp or sole, such as interior bottom, suture bottom, midsole and/or outer bottom It is equipped with the region that there is low production work with different qualities offer difference in functionality.These performances include such as bendability, drawn Stretching property (being for example expressed as Young's modulus), gas permeability and water penetration, pyroconductivity, thermal capacity, hygroscopicity, static friction, wearability, Hardness and thickness.

Using various technologies to reach this characteristic or function, this will be described hereinafter.This includes when manufacturing braid Appropriate technology, such as knitting skill, the selection of fiber and yarn, by fiber, yarn or braid be coated with polymer or its The application of his material, the use of monofilament, monofilament and combination of polymers coating, melting/fusing yarn and multi-layer braided material.It is logical Often, it can configure and (that is, correspondingly cover) yarn for being used for manufacturing braid.Additionally or alternatively, can correspondingly it configure Finished product braid.

The another aspect for the function that can be provided, is related to the tool of the braid of product specific region (such as vamp or sole) Body is used, and the connection by appropriate interconnection technique to different parts.Described aspect and technology and other aspects and technology It is explained below.

Described technology can be used alone, and can also be applied in combination in any way.

Braid

On the one hand the braid that the present invention is used is divided into weft-knitted fabric and single line knitted fabric, is on the other hand multi-thread warp knit Fabric.The distinguishing characteristics of braid is that it is formed by yarn or coil all linked with one another.These coils are also referred to as stitch, It can be made up of one or more yarns or line.

Yarn or line are the terms of one or more fibre structures, are elongated relative to its diameter.Fiber is elastic knot Structure is very thin relative to its length.Very long fiber, using hardly limited length, is referred to as filament with regard to it.Monofilament yarn is by one Individual single filament, i.e., be made up of Single Fiber.

In weft-knitted fabric and single line knitted fabric, the formation of stitch needs at least one line or yarn, and line is vertical in product Upwardly extended to side, i.e. the manufacture direction substantially with product in the fabrication process is at a right angle.In multi-thread knitted fabric, stitch Formation need at least one through piece, i.e. multiple so-called warp thread.These lines for forming stitch extend in longitudinal direction, i.e. big Cause the manufacture direction in manufacture course of products.

Fig. 1 a show substantially different between woven fabric 10, weft-knitted fabric 11 and 12 and knitted fabric 13.It is woven to knit Thing 10 has at least two line pieces, generally at right angles sets relative to each other.In this regard, line be located at over each other or under, do not have To form stitch.Weft-knitted fabric 11 and 12 is by the way that single line is woven from left to right by stitch all linked with one another. View 11 shows the front view (also referred to as front ring fabric side) and rearview 12 (enclosing fabric side after also referred to as) of weft-knitted fabric.Before The cabling enclosed with rear circle product side at leg 14 is different.In rear circle fabric side 12 covered with the leg opposite with front ring fabric side 14。

Fig. 1 b show an optional mode of the weft-knitted fabric that can be used for the present invention with so-called filling yarn 15. Filling yarn 15 is the length for the line placed between two stringers of longitudinal direction, is the x wire guarantor by other textile elements Hold.Filling yarn 15 and other textile elements are combined, the characteristic of weft-knitted fabric is have impact on and reaches multiple patterns effect. The draftability of weft-knitted fabric on stringer direction for example can be reduced by filling yarn 15.

As shown in Figure 1a, multi-thread knitted fabric 13 is by being produced with multi-thread warp knit from top to bottom.So, line The stitch stitch all linked with one another for having an adjacent lines.According to pattern, the stitch of adjacent lines is all linked with one another, produces seven kinds of basic connections One of (also referred to as multi-thread warp knit in " braiding "), such as cylindricality, tiltedly knit, 2x1 plain weaves, satin are knitted, velvet, figure are knitted (atlas) And twill.

By way of example, 21,2x1 plain weaves 22 tiltedly are knitted figure 2 illustrates braiding and figure knits 23.Different results all linked with one another How the stitch for being determined by the line 24 of emphasis citing is buckled in the stitch of adjacent lines.In braiding 21 is tiltedly knitted, pin is formed The line of pin passes through braid in longitudinal direction complications and constrains/bundle (binding) between two adjacent stringers.2x1 plain weaves are compiled 22 are knitted in the way of similar to braiding 21 is tiltedly knitted by binding/constraint, but each warp thread for forming stitch skips stringer.Volume is knitted in figure Knit in 23, each warp thread for forming stitch runs to turning point formation stair shape, then changes direction.

The stitch that set has connection binding/constraint site (binding sites) on top of each other is referred to as stringer.Figure 3 show stringer as the example of weft-knitted fabric 31.Term stringer is similarly used for knitted fabric.Therefore, stringer passes through mesh The vertical cabling of fabric.The row of stitch is disposed adjacent one another, and weft-knitted fabric 32 is shown as example in figure 3, is referred to as row.Art Language row is also similarly used for knitted fabric.Correspondingly, row passes through mesh fabric in lateral.

Known three kinds of basic Weft-knitted Structures in weft-knitted fabric, it can be known by the cabling of the stitch along stringer Not.For plain weave, single JERSEY (jersey), only have back side circle to know along the stringer on the side of fabric Not, and along the opposite side of the product back side circle recognizes.This structure is produced on row's pin of seam loop, That is, the arrangement of adjacent crochet needle, is also known as single JERSEY.For rib fabric, front and back circle is in horizontal stroke It is alternately present in row, i.e. can see that it is considered as vertical that this, which is depended on, along stringer or only front or only back side circle The sidepiece of capable product.This structure is resulted from two row's pins, and pin is relative two-by-two to offset.For purl knitting fabric, front A stringer is appeared alternatively in back side circle.The both sides of product look the same.This structure is logical by latch needles as shown in Figure 4 Cross stitch conversion manufacture.If using double latch needles, stitch conversion can be avoided, and it all includes hook and tongue in every one end (latch)。

The important advantage that braid exceedes textile is its changeable structure, and the table that can be created with structure Face.Can manufacture very heavy and/or hard braid with essentially identical manufacturing technology, and it is sufficiently flexible, transparent and/or Stretchable braid.The parameter that can be substantially influenceed by the characteristic of material has weft-knitted or warp-knit pattern, use yarn, The size of pin or the distance of pin, and the tensile stress under the influence of the yarn on pin.

The advantage of weft knitting is that some yarns can be weft-knitted in the position of unrestricted choice.By this way, it is selected Region can provide some performances.For example, the vamp for football boot can set the region being made up of rubber yarn to reach Higher stiction, hence in so that sportsman can preferably control ball.For in selected local weft-knitted some yarns, without The element for needing addition additional.

In the environment of plant, braid is manufactured by machine.These machines generally include multiple pins.In weft knitting, generally make With latch needles 41, each includes removable tongue 42, such asFig. 4It is shown.The hook 43 of the anesthesia needle 41 of flap 42, so that line 44 can be worn Stitch 45 is crossed to be drawn out, and pin 41 will not be blocked by stitch 45.In weft knitting, latch needles can generally be individually moved, so can be with Each single pin is individually controlled, so as to catch the line to form stitch.

Difference is formd between flat pattern braiding and circular knitting machine.In flat pattern seam loop, yarn feeder is along one Pin is arranged by supply pin before and after line.In circular knitting machine, pin is set in a circular manner and line is along one or more circles Pin is arranged to be supplied in the way of circus movement.

It can also include two row's parallel pins to replace single faller gill for seam loop.When viewed from the side, two row's faller gill Pin for example can be relative two-by-two at a right angle.This can manufacture more fine and closely woven structure or weaving.The use of two row's pins allows system Make individual layer weft-knitted fabric or double-layer weft knitted fabric.It is entangled in when producing the stitch in first row pin with generation in the stitch of second row pin When together, individual layer weft-knitted fabric has been made.Therefore, when produce first row pin stitch with or only with generation the The stitch of two row's pins selectively tangle up when, and/or only end tangle up with weft-knitted fabric when, double-deck latitude is made Braid.If producing the stitch in the first row of pin by additional yarn selectively with producing stitch on second row pin Loosely during tangle up, this is referred to as being spaced weft-knitted fabric.Additional yarn, such as monofilament, thus it is front and rear between the two layers Guiding, so produces spacing between the two layers.This two layers can for example by it is so-called processing be joined together.

Generally, therefore following weft-knitted fabrics can manufacture on weft-knitted machine：As soon as if only need to, with row's pin, be made Individual layer weft-knitted fabric.Can as one man it be connected with each other when using the stitch of two row's pins, two row's pins, so resulting braid Include individual layer.When using two row's pins, if the stitch of two row's pins is not connected or only connected at edge, that is just produced two layers. If the stitch of two row's pins is alternatively connected in turn by additional wire, interval weft-knitted fabric is just produced.Between additional wire is also referred to as Every line, by single yarn line machine can be supplied to supply line.

What single line knitted fabric was manufactured by moving pin jointly.Alternatively, pin is fixed, and fabric is moved.With weft knitting On the contrary, pin can not possibly be individually moved.Similar to weft knitting, with flat pattern single line warp knit and circle through braided wire warp knitting machine.

In multi-thread warp knit, coiled each other using one or more wire windings, i.e. line are adjacent.In stitch is formed, individually Warp is located at around pin, and pin is moved jointly.

Technology described here and other aspects of braid manufacture can be in " clothes knowledge ", the 6th edition, author H.Eberle etc. (open with English Title " garment technology "), " weaving and clothes vocabulary ", the 6th edition, author Alfons Hofer And " weaving dictionary ", the 11st edition, find in author Walter Holthaus.

Three-dimensional braid

Three-dimensional (3D) braid can also be produced in weft-knitted machine and warp knitting machine, raw especially in flat pattern seam loop Production.Although it is weft knitting or warp knit in single process, it still falls within the braid including space structure.Three-dimensional latitude Compile or warp knitting allows the making space braid in single process to be manufactured without suture, shearing or single-piece.

Three-dimensional braid for example can change the quantity of stitch by forming partial courses on the direction of stringer and manufacture. Corresponding mechanical process is referred to as " stopping pin ".As needed, change that can be with structure change and/or stitch quantity on row direction Change is combined.When forming partial courses, the formation of stitch is interim only along the part width of weft-knitted fabric or knitted fabric Produce.Pin is not involved in the formation of stitch, and half stitch (" stopping pin ") is maintained until weft knitting again appears at the position.So It can realize for example raised.

For example, by three-dimensional weft knitting or warp knit, vamp may finally be adjusted to the shoe tree or foot of shoe maker, and can be with shape Into sole.Flap can be for example by weft knitting into appropriate shape.Profile, structure, handle, bending, groove, opening, fastener, circle and Bag can be combined with braid in single process.

Three-dimensional braid can be used for the present invention in an advantageous manner.

Feature braid

Braid particularly weft-knitted fabric can have a series of functional characteristics and be used for the present invention in an advantageous manner.

Braid can be manufactured by weft knitting technology, the braid has difference in functionality region and while keeps it to take turns It is wide.According to pattern of stitches, yarn, the size of pin, needle gage or tensile stress, yarn is set to be located on the pin accordingly selected so as to compile The structure of fabric can be adjusted to reach functional requirements in some regions.

For example, the structure with big stitch or opening can be included in the region divulged information the need for the braid.On the contrary, The region of support and stability is needed, pore pattern of stitches, harder yarn or even multilayer Weft-knitted Structure can be used, these It is described below.In the same way, the thickness of braid is variable.

There is provided a large amount of possible for basketwork structure with more than one layer of braid, these structures provide many excellent Point.Braid with more than one layer (for example, two layers), can be with multiple rows of pin (for example, two rows) in the single stage It is weft-knitted or warp-knit on weft-knitted machine or on warp knitting machine, as above save " braid " described.Alternatively, multiple layers are (for example, two It is individual) can also be weft-knitted or warp-knit in different phase, top, and being connected to each other each other is then placed within, for example, passing through seam Thread, weld or be coupled.

Multiple layers fundamentally improve the hardness and stability of braid.In this respect, resulting hardness is depended on Which kind of which kind of layer is connected to each other by technology in degree.Same yarn or different yarns are used for each layer.For example, with Formed in the weft-knitted fabric of individual layer by multi-filament yarn weft knitting, individual layer is formed by monofilament weft knitting, its stitch is wound around 's.The draftability of particularly weft-knitted layer is because the combination of different yarns is lowered.This structure it is favourable optionally by many The layer being made up of monofilament is set between thread two layers of silvalin, to reduce draftability and increase the hardness of braid.This makes Obtain has the comfort surface that multi-filament yarn is made in every side of braid.

As saved and explained in " braid " one, another optional mode of two layers of braid is referred to as being spaced weft-knitted fabric Or interval knitted fabric.In this regard, alternating yarns are weft knitting or warp knit, are more or less loosely located at two layers of weft knitting or two layers Between warp knit, make two layers of interconnection and simultaneously as filler.Alternating yarns can include with layer identical material itself, for example, poly- Ester or other materials.Alternating yarns can also be monofilament there is provided the interval weft-knitted fabric with stability or be spaced woven Thing.

This interval weft-knitted fabric or interval knitted fabric refer respectively to three-dimensional weft-knitted fabric, but must with above-mentioned The 3D weft-knitted fabrics of formation described in the section of " three-dimensional braid " one or the 3D knitted fabrics of formation are distinguished, for any required Additional cushion or protection, for example, some regions of the flap or sole in vamp or vamp.Three-dimensional structure can be used in phase Interval is created between adjacent textle layers or between textle layers and foot, thereby, it is ensured that ventilation.In addition, interval weft-knitted fabric or interval The layer of knitted fabric can include different yarns, and this depends on positioning of the interval weft-knitted fabric on foot.

Being spaced the thickness of weft-knitted fabric or interval knitted fabric can be set according to function or wearer in different zones.Example Such as, different degrees of buffering can be realized by the region of different-thickness.For example, thin region increase bendability, therefore realize Joint or the function of muscular definition.

In addition, the layer of interval weft-knitted fabric can include different yarns, this depends on the position of foot interval weft-knitted fabric. By this way, braid for example can set two kinds of different colors in front and back.The footwear being made of this braid Face includes different colours in outside and inner side.

Another alternative embodiment of sandwich construction is bag or passage, wherein on two row's pins it is weft-knitted or it is warp-knit two spinning Tissue layer or braid are only connected to each other in some regions, and which produces hollow space.Alternatively, during two single The object of weft-knitted or warp-knit braid is connected to each other, for example, by suture, glued, welding or being coupled, therefore generates sky Gap.Padded coaming can be introduced, such as, in flap, vamp, heel, sole or other regions, such as foam is introduced by opening Material, eTPU (foamed thermoplastic polyurethane), ePP (expanded polypropylene), foaming EVA (ethylene vinyl acetate) or foam Grain, air or gel buffer pad.Alternatively, or in addition, bag can be full of filler line or interval braid.In addition, line can lead to Passage pulling is crossed, such as reinforcing, to prevent the tension loading in some regions of vamp.In addition, shoestring can also pass through This passage is directed.In addition, the line of pine can be arranged in passage or bag for pad, such as the region in ankle.So And, it is also possible to for harder fastening element, such as in cap, fin or bone insertion passage or bag.These all can be by plastics system Into such as polyethylene, TPU, polyethylene or polypropylene.

Further, the functional design for braid can also be some modifications used of weaving substantially.In weft knitting In, such as can be weft-knitted in some regions projection, rib or ripple, to realize the reinforcing in these positions.For example ripple can With by braid layer the accumulation of stitch formed.This means on one layer weft knitting or warp knit stitch to be more than it is another Layer.Alternatively, stitch is weft-knitted fabric than another layer difference on one layer, for example, with tighter, the wider or different yarns of use The weft-knitted fabric of line.All produce and thicken in two schemes.

Such as rib, ripple or similar pattern can be used for the bottom of the weft-knitted outer bottom of footwear, to provide sole line and be provided to footwear More preferable non-skid property.In order to obtain relatively thicker weft-knitted fabric, it is, for example, possible to use weft knitting technology " pleat ravine " or " half-open Shirt ", this 6th edition, is described in " clothes knowledge " in author H.Eberle etc..

Ripple can be weft knitting or warp-knit, and connection, Huo Zhe are produced so between two layers of two layers of braid Do not connected between two layers.Ripple can be weft-knitted, be used as the left and right ripple of the both sides with or without two layers of connection. Structure in braid is reached by the uneven ratio of stitch in braid front or the back side.

In the framework of the present invention, the alternatively possible of the braid of functional design is in weft knitting or warp knit Opening is set in the braid of period.It can refer to an embodiment in the present invention text that other embodiment is combined Be to include the interior bottom of braid.However, this embodiment can also be applied to suture bottom.Embodiment can also be answered equally For outer bottom.Interior bottom, suture bottom or outer bottom are generally arranged in midsole.Midsole has shock-absorbing capacity.Midsole can for example including Thus foamed material constitutes.Other suitable materials have eTPU (foamed thermoplastic polyurethane), ePP (expanded polypropylene), hair Steep EVA (ethylene vinyl acetate) or foam beads.

The braid at interior bottom, suture bottom or outer bottom includes at least one opening, divides during the weft knitting of braid or warp knit It is not weft-knitted or warp-knit.This at least one opening enables the foot of the wearer of footwear directly to contact midsole.Which improve footwear Overall shock-absorbing capacity, the thickness of such midsole can be reduced.

Preferably, this at least one opening is arranged on calcaneus bone region.Setting in this position has spy for shock-absorbing capacity Other active influence.Another position of at least one opening is possible.

However, functional design braid another possibility is that whole in the braid of vamp in framework of the present invention Body formation shoestring.In this embodiment, vamp includes braid, when the braid of vamp is weft knitting or warp knit, shoestring It is integral with braid warp knit or weft knitting.In this regard, the first end of shoestring is connected to braid, while the second end is certainly By holding.

Preferably, first end is connected to the braid of vamp in flap to the transition region in vamp half sole region.Enter one Preferably, the first end of the first shoestring is connected to the braid of vamp, the first of the second shoestring in the intermediate side of flap to step End is connected to the braid of vamp in the sidepiece of flap.The second end respectively of two shoestrings is pulled by lace hole to be used for It is footwear.

Accelerate that shoestring is integrally weft-knitted or warp-knit possibility is that have to be used for from flap to the transition region in vamp half sole region The weft knitting in domain or all yarns of warp knit braid end.Yarn preferably ends in the vamp on the intermediate side of flap Between sidepiece, and formed and be connected to the shoestring of flap intermediate side.Yarn preferably ends at the sidepiece of the vamp of the sidepiece of flap, And form the shoestring for being connected to flap sidepiece.Preferably, to be sufficiently used for being formed the length cutting continuous strand of shoestring.Yarn for example may be used Be distortion or winding.The respective the second end of shoestring is preferably provided with shoelace holder.Alternatively, the second end is melted Or it is provided with coating.

Braid due to its construction especially on stitch direction (longitudinal direction) it is scalable.This stretch can for example pass through The polymer coating of later braid is reduced.However, this stretch can also be reduced in braid manufacturing process.It is a kind of Possibility is to reduce mesh opening, i.e. use smaller pin.Smaller stitch typically results in the smaller retractility of braid.Carefully Mesh braid can for example be used for vamp (the also referred to as vamps of footwear).In addition, the stretching of braid can pass through weft knitting reinforcing To reduce, for example, three-dimensional structure.This structure can be arranged on the inner or outer side of vamp.In addition, non-stretching property yarn, example Such as, manufactured, can be laid on along braid in passage by nylon, to limit the stretching of non-stretching property length of yarn.

Colored region with multiple color can use not collinear and/or extra play to create.In transitional region, use Smaller mesh opening (size of smaller pin) is so that pigment passes through glibly.

Further effect can be realized by weft knitting insertion (inlaying works) or loop selection.Works are inlayed only to set The region of some yarns, for example, some colors.Adjacent area includes different yarns, for example, different colors, then passes through So-called processing is connected to each other.

In loop selection, for example, use two row's pins yarn different with two kinds in all regions.However, in some regions Only a kind of yarn appears in the visible side of product, and other corresponding yarns are invisible in the opposite side of product.

The product of braid manufacture one integral piece can be manufactured on weft-knitted machine or warp knitting machine.It may then pass through above-mentioned phase Technology is answered to manufacture functional area during weft knitting or warp knit.

Alternatively, product can be combined with several parts of braid, and it is not the part manufactured by braid that can also include. In this regard, each braid part can be respectively designed with different functions, for example, passed on thickness, isolation moisture, moisture The function of defeated grade.

Vamp and/or sole for example generally can be manufactured integrally by braid, or can be by different braid parts Put together.Overall vamp or part vamp can for example be separated, for example, being perforated from relatively large braid.It is larger The braid of block may, for example, be circular weft-knitted fabric or circular knitted fabric or flat pattern weft-knitted fabric or flat pattern knitted fabric.

For example, flap can be made continuous blocks and is then connected with vamp, or the single-piece with vamp can be made.For Functional design, the ridge in inner side can for example improve the elasticity of flap and ensure to produce distance between flap and foot, this Individual distance provides additional vent.Shoestring can be directed by one or more weft-knitted passages of flap.Flap can be by poly- Compound is strengthened realizing the stability of flap and for example preventing the winding of very thin flap.In addition, flap also coordinates shoe maker footwear The shape of last carving or foot.

On vamp, for example, only it can be made up of braid front portion.The remainder of vamp can include different knit Thing and/or material, such as woven fabric.Front portion can for example be located only within the region of toe, extend forwardly to toe joint or Extend to midfoot area.Alternatively, the rear portion of vamp can be made up of braid in heel area, for example additionally can be with Strengthened by polymer coating.Generally, vamp desired zone or heel can be made into braid.

Can be then braid coating such as polyurethane (PU) printing, thermoplastic polyurethane (TPU) colour band, weaving enhancing Material, leather etc..Therefore, the vamp of braid is being included in whole or in part, such as sewing as described below, splicing can be passed through Or welding, using plastic shoes with or as reinforcing member or mark toe box and for the hole of wear shoes band, vamp is set On.

For example sew, be glued or weld, constitute appropriate interconnection technique, for connect single braid and other fabrics or Other braids.Connection is the alternatively possible method for connecting two panels braid.Wherein, two edges of braid are according to stitch (being typically the pin of a pin one) is connected to each other.

A kind of possible way for solderable fabric, is particularly manufactured by thermoplastic yarn or line, is ultrasonic bonding. Therefore, the mechanical oscillation in ultrasonic frequency range are transferred on the instrument for being referred to as supersonic generator.This vibration quilt It is transferred on the fabric for passing under pressure through supersonic generator connection.Because produced friction, fabric is heated, softened simultaneously Finally supersonic generator is connected in textile area.Ultrasonic bonding allows quick and economically connected especially with plastics yarn The fabric of line or line.For example by being glued or by solder design colour band, extraly strengthening weld seam, this is optically more beautiful See.Further, since avoiding skin sensitivity (especially in the transition of flap) adds snugness of fit.

Connection to different fabric extents can occur in entirely different position.For exampleFig. 5 a and 5bIt is shown, connection shoes The seam of face difference fabric extent can be arranged on diverse location.Fig. 5 aShown vamp 51 includes two Hes of fabric extent 52 53.They are sutured to each other.The seam 54 for being connected to two fabric extents 52 and 53 is obliquely extended to from the instep region of vamp From mesopodium to the sole region of the transitional region of heel.In figure 5b, seam be also it is oblique run through, but oblique toe is more Anterior direction.Other settings of seam and link position are typically can be thinkable.The seam shown in figs. 5 a and 5 b can To be linear slit, splicing seam, soldered or be coupled seam.Two seams 54 and 55 can be installed in side or the vamp of vamp 51 Both sides.

The use of adhesive tape constitutes the further possible mode of connection fabric extent.Existing company can also be additionally implemented for Connect, for example, cross on seam or soldered.Adhesive tape can further realize the function in addition to linkage function, for example Dust protection or waterproof.Adhesive tape can include the characteristic changed according to its length.

A kind of embodiment is shown in Fig. 6 a, 6b and 6c, vamp 51 is connected to the sole 61 of footwear by adhesive tape.Each figure 6a, 6b and 6c show the cross section of the footwear of foot diverse location and the thus deformation of caused footwear.For example, tensile force applies On on the right side of footwear in Fig. 6 a, and compress and be applied to left side.

The sole 61 of footwear can be outer bottom or midsole.Vamp 51 and sole 61 are connected to each other by the adhesive tape 62 of surrounding. Adhesive tape 62 can be the elasticity of change along its length.For example, adhesive tape 62 especially can be rigid and in the heel of footwear Region is not very flexible, to provide necessary stability to footwear in heel area.This can be by adhesive tape 62 for example The change of width and/or thickness is realized.Adhesive tape 62 may be generally configured to receive certain in some regions along band Power.So, vamp is not only connected to sole by adhesive tape 62, also realizes structure-reinforced function simultaneously.

Fiber

Yarn or line for the braid of the present invention include fiber respectively.It is very thin as discussed previously with respect to its length Elastic construction be referred to as fiber.Fiber growing very much, on its use hardly limited length is referred to as filament.Fiber quilt Spin into or wind inlet wire or yarn.However, fiber can also be very long, and rotate into yarn.Fiber can be by natural or people's producing material Material is made.Natural fiber is environmentally friendly, because they are degradable.Natural fiber include for example cotton, wool, alpaca fibre, fiber crops, Cocoanut fiber or silk.Wherein synthetic fibers are polymer-based fibers, for example, respectively nylon (Nylon^TM), polyester, spandex or Elastic polyurethane fiber fiber, or Fypro (Kevlar^TM), as classical fiber production or high-performance fiber or science and technology can be used as Fiber is produced.

It is contemplated that footwear are assembled by some, with weft knitting or warp knit part, weft knitting or warp knit part include by Natural yarn and such as removable portion including plastics that natural fiber is made, for example, interior bottom.In this approach, two parts can To be separately configured.In this instance, weft knitting part can perform degraded waste, and the recovery that interior bottom can perform such as material is repeated Utilize.

As shown in fig. 7, the machinery and physical property of fiber and the yarn being produced from it are determined also by the cross section of fiber. Different cross sections are described below, the example of their performance and the material with this cross section.

Fiber with circular cross section 710 can be solid or hollow.Solid fibre is most common type, it It is flexible, soft-touch.A kind of hollow cylindrical fibre is identical with the weight/length of solid fibre, and with bigger cross section, and And more resistant to bending.Example with circular cross section fiber is nylon (Nylon^TM), polyester fiber and Lyocell fibers.

Fiber with bone-shaped cross section 730 has the characteristic of moisture absorbing and sweat releasing.The example of material with this fiber is Acrylic acid and spandex fibre (Spandex).Concave regions between in the fibre support moisture to transmit in a longitudinal direction, moisture quilt Quickly take away and scatter from specific place.

Following cross sections are further shown in Fig. 7：

Yarn

Available for a variety of different yarns of manufacture braid, available for the present invention.Limited according to us, relatively It is referred to as yarn in the structure that diameter is long one or more fibers.

Functional yarn can transmit moisture and therefore absorption sweat and moisture.They are conductive, self-cleaning, hot adjust Save and heat-insulated, anti-flammability and absorption ultraviolet, can be with infra-red radiation.They touch very comfortable.Antimicrobial yarn, example Such as silver yarn, prevent from forming peculiar smell.

Stainless steel yarn contains the fiber being mixed by nylon or polyester fiber and steel.Its characteristic include high-wearing feature, High cutting resistance, high Hot wear, high-termal conductivity and high conductivity, higher tensile strength and high weight.

In the fabric being made up of braid, conductive yarn can be used for the integrated of electronic equipment.These yarns for example to The pulse that equipment transmission comes from sensor is used to handle pulse, or yarn can have sensor function in itself, and for example Measure the electric current on skin or physiology magnetic field.Can be in european patent application EP1916323 using the example of fabric base electrode Find.

Fusing yarn can be the mixture of thermoplastic yarn and non-thermal plasticity yarn.There is the fusing yarn of substantially three types Line：By the thermoplastic yarn of non-thermal plasticity yarns loop；By the circular non-thermal plasticity yarn of thermoplastic yarn；With the heat of pure fusing Plastic material yarn.After fusion temperature is heated to, thermoplastic yarn is with non-thermal plasticity yarn (for example, polyester or nylon^TM) Melting, hardens braid.It is thus determined that the melting temperature of thermoplastic yarn, and melting temperature is usually less than blended yarns Non-thermal plasticity yarn melting temperature.

It is dual-element yarn to shrink yarn.Outer member is shrink-down material, is shunk when more than limiting temperature.Inner member It is non-contraction yarn, such as polyester or nylon.Shrink the hardness for adding textile material.

Another yarn for braid is luminous or reflective yarn and so-called " intelligence " yarn.Intelligent yarn Example be to wet air and heat or it is cold and therefore change the aitiogenic yarn of characteristic, for example, shrink and therefore make stitch diminish or Change volume and therefore increase the permeability of air.The yarn being made by piezoelectric fabric or covered with piezoelectricity isoelectric substance can be converted Kinetic energy or under stress change turn to electric energy, so as to provide energy for such as sensor, conveyer or battery.

Yarn is further generally done over again, for example, upper coating, to maintain certain characteristic, such as stretching, color or resistance to It is moist.

Polymer coating

Due to its structure, weft knitting or warp knit braid is more more flexible than woven fabric material and draftability.For some Using and require, for example, according to the present invention vamp or sole certain area, it is therefore necessary to reduce elasticity and draftability with Reach enough stability.

For this purpose, polymeric layer may apply to the one or both sides of braid (weft knitting or warp knit article), but logical Often it is applied to other textile materials.This polymeric layer causes the reinforcing and/or hardening of braid., can be such as on vamp Support and/or harden in toe area, heel area, along lace hole, side and/or intermediate surface or in other regions And/or reduce elasticity.In addition, reducing the elasticity of braid, particularly draftability.In addition, polymeric layer protection braid is prevented Only wear and tear.Furthermore, it is possible to which the method for the polymer coating for passing through compression molding makes braid have 3D shape.

In the first step of polymer coating, polymeric material is applied to the side of braid.However, it is also possible to be applied to two Side.Material can coat, lay, print, sinter, press or apply by spraying, using scraper to apply.If film shape The polymeric material of formula, film is located on braid and is connected for example, by the mode for heating and pressurizeing with braid.Application side Method is above all sprayed.It can be applied by the instrument similar to hot glue gun.Spraying make it that polymeric material is uniformly applied On thin layer.In addition, spraying is fast method.Effect pigment, such as coloured pigment, may be mixed in polymer coating.

Polymer is applied at least one layer that thickness is preferably 0.2-1mm.One or more layers can be applied, therefore, it is possible to make Each layer has different thickness and/or color.Between the adjacent area with polymer coating of various thickness, from poly- The region of compound coating can have continuous transformation to the polymer areas with thick coating.In the same way, different polymerizations Thing material can be used for different regions, and this will be described below.

During applying, on the one hand polymeric material is attached respectively to contact point or the crosspoint of braid yarn, another Aspect, is attached between the interval of yarn, forms closure polymer surfaces on braid after following process steps.So And, in the larger mesh opening of fabric construction or hole, this closure polymer surfaces can also be interruption, for example, being easy to Ventilation.This also depends on the thickness for applying material：The polymeric material of application is thinner, and closure polymer surfaces are more easily interruptions 's.In addition, polymeric material is also through yarn and infiltrates yarn, therefore it is contributed to harden.

After polymeric material is applied, braid is suppressed at high temperature and pressure.Polymeric material dissolves in this step And melted together with the yarn of textile material.

In further optional step, braid can be compressed to 3D shape in the machine of compression forming.For example The heel area of vamp or toe area can be three-dimensionally shaped by the shoe tree of shoe maker.Alternatively, braid can also directly with Foot engagement.

After compacting and shaping, until the reaction time for completing hardening can be one to two day, this depends on what is used Polymeric material.

Following polymeric materials can be used：Polyester；Polyester-urethane prepolymer；Acrylates；Vinegar ester is fine Dimension；Reactive polyolefin；Copolyesters；Fypro；Copolyamide fibre；Reactive system is (with H₂O or O₂The poly- ammonia of reaction Ester system)；Polyurethane resin；TPU；And polymeric dispersant.

Proper range of the polymeric material viscosity at 90-150 DEG C is 50-80Pa s (pascal second).It is particularly preferred that Proper range at 110-150 DEG C is 15-50Pa s.

The hardness preferred scope of hardening polymer material is 40-60 Shore Ds.According to application, it is also contemplated that hardness Other scopes.

Described polymer coating can be reasonably used for any desired support function, hardening, increase wearability, stretching The elimination of property, increase comfortableness and/or be engaged to specified three-dimensional shape in the case of.It is contemplated that for example by vamp and dress The unique shape of person's foot coordinates, and is applied to vamp using polymeric material, foot is then adapted at high temperature.

Monofilament for reinforcing

As we have limited, monofilament is the yarn being made up of single filament, i.e. single fiber.Therefore, the drawing of monofilament Stretching property is more much lower than the yarn being made up of many fibers.This reduces the draftability of braid, the braid is by monofilament system Into or including monofilament and for the present invention.Monofilament is especially made up of Fypro.However, it is also possible to expect other materials, example Such as polyester or thermoplastic.

But the braid being made up of monofilament is fairly hard not too much with draftability, this braid is without desired Surface characteristic, such as smoothness, color, moisture transmission, outward appearance and the various fabric constructions having such as conventional braid.

This defect can be overcome by following braids.

Fig. 8 is depicted with the weft-knitted layer being made up of the first yarn (such as multi-filament yarn) and the weft knitting being made up of monofilament The weft-knitted fabric of layer.Layer of filaments is incorporated into the first thread layers by weft knitting.Two layers obtained of braid is than by the separately made layer of yarn It is more firm and with smaller draftability.If monofilament starts to be melted slightly, monofilament melts even better with the first yarn.

Fig. 8 specifically depict the front view 81 and rearview 82 of two layers of braid 80.Two views are shown by the first yarn Thread first weft-knitted layer 83 and the second weft-knitted layer 84 being made up of monofilament.Led to by thread first tissue layer 83 of the first yarn Cross stitch 85 and be connected to the second layer 84.Therefore, the bigger hardness for the second tissue layer 84 being made up of monofilament and smaller stretching Property is transferred to by thread first tissue layer 83 of the first yarn.

Monofilament can also slightly melt to be connected to the first thread layers and limit bigger stretching.Monofilament is in tie point and first Yarn is melted, and the first yarn is fixed relative to the layer being made up of monofilament.

The combination of monofilament and polymer coating

As described in previous sections, strengthen with two layers of weft-knitted fabric additionally by polymer coating, as " poly- The section of compound coating " one is described.Polymeric material is applied on the weft-knitted layer being made up of monofilament.So do, polymeric material not with Monofilament material (such as polyamide material) is connected, because monofilament has very smooth and round shape surface, but substantially penetrates first First layer below yarn (for example, PE yarn).In subsequent compacting, the yarn of polymeric material therefore with first layer Melt and strengthen first layer.So do, polymeric material has lower than the first yarn of first layer and the monofilament of the second layer melt Change point.Selected temperature causes only polymeric material melts during pressing, and monofilament or the first yarn are non-fusible.

Melt yarn

In order to strengthen and reduce stretching, additionally or alternatively, the yarn of braid used according to the invention can be Yarn is melted, braid is fixed to after pressing.There is the fusing yarn of substantially three types：By the heat of non-thermal plasticity yarns loop Plasticity yarn；By the circular non-thermal plasticity yarn of thermoplastic yarn；The pure fusing yarn of thermoplastic.In order to improve thermoplasticity Combination between yarn and non-thermal plasticity yarn, can have texture on the surface of non-thermal plasticity yarn.

Compacting preferably occur in 110 to 150 DEG C of scope, especially advantageously at 130 DEG C.Thermoplastic yarn is in processing Middle at least part fusing, and melted with non-thermal plasticity yarn.After pressing, braid cools, and so combines and is hardened and consolidates It is fixed.Fusing yarn can be arranged on vamp and/or sole.

In one embodiment, fusing yarn enters braid by weft knitting.In the case of multiple layers, fusing yarn can be by One layer, multilayer or all braid layers are entered in weft knitting.

In this second embodiment, fusing yarn can be arranged between two layers of braid.So do, fusing yarn can To be simply provided between layer.Had the advantage that in the setting of interlayer, during compacting and shaping, mould is not tinted, because Not contacted directly between fusing yarn and mould.

Thermoplastic fabric for reinforcing

It is to use thermoplastic to strengthen for another possible mode of the braid of (such as in vamp and/or sole) of the invention Property fabric.This is thermoplasticity woven fabric or thermoplasticity braid.Thermoplastic fabric is at least partly melted by heating, and is worked as It is hardened when cooling.Thermoplastic fabric (can for example be wrapped by applying pressure and the hot surface for being for example applied to vamp or sole Include braid).When its cooling, thermoplastic fabric's hardening and especially for example in the region reinforcing vamp or sole of its arrangement.

Thermoplastic fabric is especially in the manufacture of its shape, thickness and structure for reinforcing.In addition, its characteristic is in some areas Domain can change.Pin structure, braiding stitch and/or the yarn used can change, to realize different spies in different zones Property.

The embodiment of thermoplastic fabric is the thread weft-knitted fabric of thermoplastic yarn or knitted fabric.Additionally, Thermoplastic fabric can include non-thermal plasticity yarn.Thermoplastic fabric can for example be applied in the vamp of footwear by pressure and heat Or sole.

The parallel and/or warp of woven fabric are thermoplastic, and this is another embodiment of thermoplastic fabric.Can be The weft direction and warp direction of thermoplasticity woven fabric use different yarns, to realize different qualities, such as in weft direction With the draftability of warp direction.

The interval weft-knitted fabric or interval knitted fabric that are made up of thermoplastic are another embodiment party of thermoplastic fabric Formula.In this regard, such as only one layer is thermoplastic, so as to for example be attached to vamp or sole.Alternatively, two layers is all heat Plasticity, sole is connected to vamp.

It can use and save the process technology of the braid of description to manufacture thermoplasticity weft-knitted fabric or warp in " braid " one Braid.

Thermoplastic fabric can be connected to the surface for staying in point reinforcing of pressure and high-temperature lower part, so only have some regions or Some regions of only thermoplastic fabric are connected to surface.Other regions or other region are not connected, such gas permeability and/ Or moisture is for example kept.The function and/or design of such as vamp or sole can be changed accordingly.

Vamp

Fig. 9 shows the schematic top plan view of the first embodiment according to vamp 51 of the present invention.Vamp 51 includes multiple the A part 91, the plurality of Part I is applied to accommodate at least one toe of each foot.When be provided with according to the present invention When the footwear of vamp 51 are worn by wearer, the toe of wearer is located at Part I 72.

Vamp 51 in Fig. 9 includes five Part I 91, it is meant that for each toe, all with some 91 Independent Part I.However, it is also contemplated that two or more toes are assigned into an independent Part I.

For example, big toe can be assigned to independent Part I, while remaining toe is assigned to common first Part.Therefore, vamp 51 can include two Part I altogether.

Toe can be not assigned to Part I.Such as opening of vamp 51 can cause one or more toes from outside Visually.

Vamp 51, which is arranged to Part I 91, essentially independently to be moved each other so that toe be free to move to it is some Scope, i.e. toe is moved without restriction in the case of the footwear that it is common.Toe is produced with ground by sole and independently connect Touch.In this regard, in the case where a part is mobile, its adjacent part is due to the frictional force or power on vamp 51 and/or sole Transmission, can slightly move.

Essentially independent due to Part I 91 is moved freely, and toe largely independent can also be moved relative to each other It is dynamic.This generates similar to the sensation of walking naturally walked barefoot.Toe can be moved freely and individually contacted with ground, and energy Enough experience ground.The grasping movement of single toe is also possibly realized.

The formation braid of Part I 91 in Fig. 9, can be manufactured by the explanation in the section of " braid " one.Fig. 9's In example, including the forefoot region 92 of Part I 91 forms braid.Unnecessary formed of the remaining area 93 of vamp 51 is compiled Fabric, because the seam connecting belt in this region carrys out less worry.Knitted it is contemplated that region 93 for example forms thicker, flexible woven Thing or the material for forming another traditional footwear.

However, it is also possible to expect be：Only the formation braid of Part I 91 of vamp 51, and other areas of vamp 51 Domain does not form braid.Alternatively, whole vamp 51 can form braid.For example, forefoot region 92 can be Weft knitting, and remaining region 93 is warp-knit, vice versa.

It is contemplated that vamp 51 is formed by single-piece braid.For example, vamp 51 can be continuous weft knitting or continuous warp knit 's.In the case, in the absence of the different region 92 and 93 of braiding purposes.But in the case, the weft knitting in region 92 and 93 Or warp knit structure or used yarn can be different.More open pin structures can be used for the toe in forefoot region 92 Ventilation, but more close weft-knitted fabric is used for side to increase stability.Reinforcer, can be with such as rib, passage, bag Be weft knitting or through being incorporated into region 92 or 93 to accommodate reinforcer or similarity piece.Colour band can be by weft knitting.

Then Part I 91 can be linked together with separately fabricated for braid by being coupled.During being coupled, braiding The edge of thing part links together in the way of row is oriented to, i.e. stitch connects stitch connection, will not so produce thick seam. These for example can be coupled completion on machine.

Part I 91 can alternatively be made up of single-piece braid.For example, part 91 can be on circular knitting machine Weft knitting.However, the manufacture on flat pattern seam loop or weft-knitted machine is also possible.On flat-type weft knitting machine device, braid Vamp upper layer and bottom can be saved such as " braid " one it is described, every two layers respectively using row's pin weft knitting simultaneously.Two layers can It is connected to each other with the profile along footwear and therefore forms the cavity for foot.Two layers can not exclusively flat pattern weft knitting but three-dimensional latitude Compile, such net shape is corresponding with foot, such as section of " three-dimensional braid " one is described.

Part I 91 is manufactured by connection or single-piece, without generation seam between Part I 91.This means pin The connection of Part I 91 is seamless completion between toe.Braid can be wrapped in other regions between being not located at toe Include seam.
