Description

A kind of vamp material and manufacture method thereof and application
Technical field
Advantageous applications of the present invention is on sport footwear and described the method that is used to improve vamp outer surface gripping power.
Background technology
The performance of a plurality of factor affecting sport footwears.Also there is concrete many groups service condition in different application for footwear.For example, cross-country trainer has visibly different consideration than making the footwear that is used in the ball game, and wherein these footwear can be used to play football or touch ball.The consideration that manufacturing is used in the footwear in the ball game is that the present invention itself relates generally to.Yet this does not get rid of the manufacturing that the present invention can be used for the footwear of other types in succession.
Also exist and influence the different piece of footwear and many groups of different considerations of manufacturing thereof.Although these considerations are not exclusively separate, the present invention mainly concentrates on the structure of the vamp of footwear.The character of vamp not only influence with the ball contact process in the performance of the footwear experienced, and influence the overall performance of footwear, for example global stiffness, pliability or the like.For this reason, mostly make be used for ball game footwear always according to quite traditional method, for example, although many other fabrics and material are used on the vamp of sport footwear of other types, the leather of sport rank is preferred building material.
Is that not only the performance with overall footwear is relevant to the preferred of leather to small part, and sensation and the performance to footwear experienced with the sportsman are relevant.Most change to vamp material comprises adopting to have different physical characteristics (for example thickness, texture etc.) or dissimilar leathers (for example from different animals).Often on high-quality footwear, do not adopt synthetic leather.
Yet, although there be a large amount of the change by manufacturing like this so that also there is significantly restriction in the parameter of the performance of footwear and characteristic variations.In these restrictions one comprises " contact gripping power (contactgrip) "-grabbing degree between them when footwear and ball contact.This is the key factor that performance is experienced in decision.Exist when well grabbing, the essence of contact is with the two is more consistent as a result.This is converted into the sportsman usually and improves their technical ability more quickly because the ball reaction (with process that ball contacts in) uniformity and predictability the sportsman is reduced concentrate on the erratic behavior of proofreading and correct.And ball slips over the vamp surface and the time causes being difficult to precision of prediction and behavior, and requires the sportsman to make correction by the light of nature according to they self technical ability with to the maneuvering performance of footwear.
Most existing ball game footwear (for example football boots) from standard movement are being provided by the suitable predictable behavior that provides on the ground.However, it is all undesirable and seldom produce desirable behavior outcome to contact in the situation gripping power in all possible (with ball).This a big chunk is relevant with the degree of grabbing between ball and the footwear.In the place that has very little gripping power, might between ball and footwear, produce sideslip, slide and other undesirable interactions.Cause like this undesirable behavior on footwear, occurring and experiencing performance issue.
A quite considerable problem is proposed like this.Although the footwear of standard provide suitable but unfavorable performance in dried ground, the competition and training time carries out under wet or damp condition mostly.This is the obvious place of losing efficacy of standard movement leather of current footwear.Even only there is a contact surface to wet, coefficient of friction also significantly descends.In the standard testing of Miao Shuing, the coefficient of friction of doing the motion leather is 0.8 later, and wet motion leather is 0.3.This provides the influence indication of humidity on the typical leather.Even it is also relatively low to do motion leather coefficient of friction, and makes the tissue textureization of leather only this coefficient can be brought up to about 1.7.Therefore there are some tangible restrictions in the performance of leather that is used as on the ball game shoe construction, and this is converted into the significant limitation to the optimum performance of described footwear again.
Therefore, need provide the performance of the sport footwear that a kind of raising is used for ball game and experience performance (at the sportsman's) method.
The inventor is not unique people who recognizes with these kinds of athletic footwear relevant issues.The method that was applied in the past on the footwear concentrates on the veining method always, so that the material surface that is adopted becomes coarse or introduce that protruding features improves drainability and as the stronger physics convex surfaces of desirable gripping power.Example comprises the rubber projections (US 3,191,321) of Brutting and the shaping (US5,437,112) of Johnson.Also put down in writing for example sharkskin (WO0307745) of exotic material.Yet these improve the wet raising of grabbing performance that the qualified and inadequate acceptance in edge only is provided, and be cost to make difficulty or ease, cost and pliability.The most important thing is that they have often reduced athletic feedback in ball contact process.This reason that perhaps to be leather take advantage in the structure to the vamps of sport shoes of ball game.So the direction that prior art is studied can not produce the quality that satisfies any outstanding of sportsman and the same needs of producer or significantly improve.
Thereby, to go back actual needs a kind of method that is used for producing the sport footwear that uses in ball game is provided, this method provides grabbing performance but can being not cost to reduce sportsman's feedback or complicated vamp manufacture method of raising.Can adopt the manufacture method of the standard basically that is used to produce leather-instep ideally and produce machine.
Therefore the objective of the invention is to solve these misgivings.
Another object of the present invention provides a kind of method that has the footwear of grabbing performance of raising or be used to improve the footwear with described performance on wet vamp at least a portion.
At least the objective of the invention is provides effective alternative to the public.
Describe to various aspects of the present invention with the mode by example only and with reference to subsequently description.

The present invention relates to material, improves the method for material, to improve the surface property of their outer surfaces in first example.Usually, in the context of the present invention, this means ideally to improve and grabbing performance or coefficient of friction under wet and the dried condition.Under wet and dried condition, obtain potential especially very favourable of suitable coefficient of friction to sports goods and sport footwear manufacturing.Will know the method for recognizing material and being used to handle material from specification, book mainly concentrates on sport footwear and relative consideration for the purpose of simplifying the description.Yet should expect that material of the present invention can also be applied in the occasion except that sport footwear, and can be applied in the gloves kimonos and load onto.
The invention still further relates to footwear, preferably the sport footwear in ball game for example.Described common sport footwear for example the common problem of football boots be that they become when humidity and easily skid and lose gripping power.This has obviously reduced the accuracy that the sportsman plays football according to concrete impact power when sliding or scud in the boots surface or rotates at ball.
The present invention has introduced the wet at least method of grabbing performance of the part of the whole vamp that is used to improve footwear or vamp.This method comprises at least and to improve about the standard leather that is used for sport footwear and the wet performance of grabbing of dermatine material in the text.The invention allows for the improvement (if the user has a preference for this material) of the leather of sport rank, it is applicable to the most manufacture method to the leather vamps of sport shoes.
The present invention includes to the material of structure vamp or to the material (for example sticking patch vide infra) that can be coated on the vamp and apply the coating that suitable gripping power improves.Preferably before the assembling of vamp, carry out coating process, for example the material of making vamp is carried out precoated shet.Yet this is not precluded within the vamp construction process or after the vamp structure and carries out coating process, perhaps carries out coating process in the different time.
The present invention utilizes special coating scope.These preferably include the butylene type coating, and this coating has the PIB polymer.The PIB polymer is one that is selected from down in the group in the context of the present specification: polyisobutene (is also referred to as butyl rubber, 2-methyl isophthalic acid-Noblen, isobutene polymer, polymerization 2-metering system, isobutylene resin, and has molecular formula: [C 4H 8] n), and polyisobutene-isoprene copolymer.A kind of special existing product is the product TPC1105 from Texas Petrochemicals, and it is the PIB with 1000RMM.
Usually butylene-isoprene copolymer comprises 0.01%～5% the isoprene and the isoprene of nominal 1% ± 0.5%.These can be " enhancing " copolymers, and wherein isoprene is distributed on the whole polymer with going up homology substantially, however can also be the copolymers of " highly reaction ", and wherein the non-homology of isoprene ground distributes.Two kinds preferred in, the present invention adopts " enhancing " copolymer.
Butylene-isoprene copolymer can also be crosslinked, and is although this crosslinked coating also within the scope of the invention, preferably noncrosslinking copolymer coated.
In order to be used for the present invention, require the butylene type coating can be easy to be applied to substrate for example on the leather, however do not get rid of constructional other materials of the vamp that is used in footwear and fabric.Particularly importantly, should be able under especially wet or damp condition, improve the coefficient of friction of substrate.As criterion, the material ranges that comprises the preferred embodiment for the present invention is implemented some tests.
When adopting the improvement IUP51 test step (vide infra) of leather technology teacher and chemist international federation (International Union ofLeather Technologists and Chemists) appointment, the value of coefficient of friction surpasses 2.0 ideally.More preferably coefficient of friction should surpass 3.5.In ideal material, the coefficient of friction when wet is substantially equal to or is higher than coefficient of friction when doing.Coefficient of friction also should surpass 2.0 during described ideally material or coating wet, preferably surpasses 3.5.Improved test is according to the standard testing of adopting PTFE benchmark bed, but improved at this be the leather that is used for football boots production with polyurethane coating.
By way of example, below list some representative datas of the different materials of testing by the inventor:
Figure C20058001774600121
According to leather technology teacher and the IUP51 of chemist international federation test.
Like this can to preferred polyisobutene class material of the present invention and standard material and inventor in his other inventions for example in PCT/AU 2004/001545 development or the various dried material of grabbing that adopts compare.
Can see that butylene type coating of the present invention has a plurality of attainable advantages when being coated on the leather at least.An advantage is the coefficient of friction that significantly improves base material under wet and dried condition.Another advantage is that to compare maintenance under gripping power and the dried condition under the wet condition relative consistent.This uniformity competition and training condition especially in use is effective especially when changing.
The inventor has determined one group of butylene type coating that is used to make the preferred feature of vamp.For example, the preferred RMM (relative molecular weight) of PIB polymer (comprises end points) between 600～1500, however, is more preferably between 850～1200 and (comprises end points).This is viscous liquid normally.Should have transparent definition fully ideally.Back one RMM scope especially can form and be described to discrete film, and the PIB polymer can be stored in the internal fiber matrix of substrate, and it will constantly ooze out to replace the PIB polymer of wearing and tearing/use on the leather surface.
The PIB polymer of (comprising end points) is feasible in the present invention in the wideer RMM scope 500～1800, but always unfavorable at the RMM of the boundary of this scope.For this reason, determined above preferred scope.Requirement obtains to be detained but is not adhesion surface.To adsorb too many dust and dirt if adhere very much in the surface, unless be not clean enough, otherwise these dust and dirt will be smeared the surface, and for example the transparent wrapper bag is similar with only using once or twice adhesive tape for this.If it is softer PIB that continuous film is designed to, then its durability is restricted." have discrete film " and have some attainable advantages.
Desirable target is to have to provide grabbing the performance raising but coating durable simultaneously and that performance is consistent.Inventor's research has obtained above-mentioned preferred PIB polymer features.
The butylene type coating generally includes solvent, especially under the situation that adopts painting method.Carrier that is adopted or solvent can change, and however preferably include in the following material one or more: paraffin, mineral oil, benzene, toluene, thiacyclohexane, dimethylbenzene, carbon disulfide, chlorobenzene, hydrocarbon, halogenated hydrocarbons and compatible organic solvent.Paraffin oil has still less dangerous problem than multiple other solvents, and can be preferred.Yet, can improve coating method of coating by adopting multiple volatile solvent.The user can have selected and selection to a certain degree.
The butylene type coating is coated in does not need subbing usually in the substrate.Yet, should guarantee fibre structure " enough open " thus can be easy to see through arrives substrate.For example, if the surface is sealed very much, then the PIB polymer will be difficult to infiltrate enough degree of depth.For example, on leather, can/softening action soft by drawing with sudden force overcome this defective to break texture, however this method can be used for for example he-goat leather of some leathers modestly.It is desirable to the veining leather, the some of them texture is eliminated, roughening or improve to obtain permanent surface design effect, perhaps velvet leather or kid leather.Height waterproof or resistant to pollution leather can cause the slight resistance of PIB mixture, and need to consider the accurate shaping and the painting method thereof of butylene type coating.Can expect according to the present invention, wish that the user who optimizes butylene type coating or its painting method needs certain test.It is believed that this is just in the skilled worker's who obtains this specification information limit of power.
Can apply the butylene type coating in several ways.For leather, can consider for example roller coat of standard coated machine or method.Require the one-sided of coating leather only or substrate for typical sport footwear structure.
Both sides all apply can be uncomfortable, and be difficult to pin is inserted in the footwear, unless be added with liner in footwear.Two-sided coatings is also wasted coating material, and can increase manufacturing cost.
The butylene type coating can be coated in the substrate of making vamp at least in part, perhaps is coated on half vamp of constructing or constructing fully, perhaps is coated on the whole footwear.Can also apply more than a coating, and these coatings can apply in the identical or different fabrication stage.
The coating amount that applies also can change, and can be used to change other physical characteristics of substrate in some cases.For example, the amount of the PIB polymer of increase introducing can make leather feel heavier and more tacky.Can this requirement be proposed to sticking patch on the vamp (vide infra) or specific region.Therefore, exist available user's range of choice with further raising practicality of the present invention and validity.
Preferably, for the constructional motion leather of sport footwear, we may be with reference to butylene type coating method, makes PIB density polymer on the final leather in the scope that comprises end points 1～70g/sq.ft, however is more preferably in 14～32g/sq.ft scope.
Coating can apply along substrate basically continuously.In these cases, the vamp part that can for example be had coating by the different piece of the material with different qualities and not have a coating is made.Yet some are handled and painting method itself brings multiple choices can for them.For example, for example coated in a different manner or processing of leather (in the present embodiment) meeting of sheet material for example provides the part that has coating or do not have coating.Different piece (if comprising fuel or pigment) can comprise visual material for example literal, figure, sign or other marketing materials.Another variation is the part with pattern that improves the performance of footwear or improve some performance of sportsman.These feasible programs provide some other potential attainable advantages for the producer of sportsman and footwear.
For example adopt the butylene type coating that the characteristic of other raisings can be provided the structure of footwear on the leather in substrate.The important organoleptic attribute of common football player is comprised robustness, pattern and the shape of footwear and compliance factor for example soft feel and shape.Usually contain rubber toe insert so that some in these characteristics to be provided, but increase to cost to pay some other characteristic and weight.Have been found that the leather that adopts the butylene type coating makes footwear that good aesthetic quality be arranged but need not the toe insert.Significantly weight saving is an advantage point to the sportsman, is an advantage point and there is not optional feature to the producer.Therefore aspects more of the present invention can provide the attendant advantages that only improves outside the gripping power.
The present invention's another potential attainable advantage relevant with leather is the often internal fiber of coating leather structure of PIB polymer.Make fiber that the sweat (lactic component of more specifically saying so) that is easy to damage leather is had repellence like this, chrome tanning system leather and the chromium of particularly removing tanning material cover the waterproof leather.The normal erosion that is subjected to lactic acid can cause the leather hardening, can reduce intensity so again, impels real area to shrink, and allows variable color and provides bacterial growth and the suitable environment of existence.The present invention adopts butylene type coating material can avoid these problems on the leather of vamp.
Should be noted that according to the present invention and improved the water proofing property of leather substrate by applying the butylene type coating.Test shows adopt static state suction in water and deflection test (percentage of measurement infiltration time and suction) for example The Maeser Flex Test (by SATRA-Britain Kettering footwear and the specified test STM106/106D of research association of business alliance) water proofing property on average improve 30%.So increased the water resistance of footwear, meaned that finally footwear keep lighter in whole wet environment match.This is another potential attainable advantage of the present invention.
Test shows to be found by the tensile strength of the processing leather that utilizes the butylene type coating and shear strength and is improved.Studies show that and obtained 10%～15% raising.It is believed that this is because the PIB polymer has auxiliary fat liquoring effect to the leather fiber structure, finally cause giving lubricated being improved of internal fiber matrix of additional strength.
Research shows that also simple veining performance of leather has had raising.This point can illustrate by following basic principle, and promptly just because the veining leather can be to reduce the water layer effect in the raceway groove between peak and the highland by the embossed area that makes water drop on leather surface, so it has improved to wet and is grabbing performance.Yet, ignore the possible distortion in these peaks and highland in ball contact process, only there is the summit on these peaks and highland in fact can contact ball, this is littler than total surface area.When on the surface area that only reducing of contact effectively the time, the improvement of butylene type coating gripping power of the present invention will improve conspicuous gripping power.Therefore our vent channels that is used for surface water has improved the gripping power of leather.
Simultaneously can apply the wet gripping power of sticking patch to footwear within the scope of the present invention to provide some advantage of the present invention for example to increase.Usually these sticking patch will provide substrate and outer surface.Outer surface has applied the butylene type coating at least in part so that the performance of grabbing of raising to be provided according to the above.Therefore substrate and outer surface can comprise a leather substance after the processing, perhaps any other material.
The bottom surface can comprise adhesive coatings.Can be permanent or impermanent adhesive, make sticking patch can temporarily use or be placed in again the appropriate location.Detachable over cap can be provided in the adhesive reverse.
The bottom surface can not comprise adhesive, but can be suitable for adhesive material.Can select to adopt different adhesives like this, and can in manufacture process or by the person of mending shoes or other suitably competent people, be applied on the sticking patch that applies.The bottom surface can be absorbefacient, have keyway or other and improve to improve adhesiveness.
Can be provided for connecting other fastening forms of sticking patch.For example, can consider hook and for example pile up securing member
Can recognize that the present invention has many variations, and the present invention can there be many embodiments.To concrete embodiment be described by the mode of embodiment below.
