Background of invention
The gloves that constitute for non-water-tight leather or fabric are made the Handcovering of waterproof, and people are always in effort.Provide the lining or the plug-in unit of waterproof in the gloves housings, can make gloves have water proofing property.For comfortableness is provided, waterproof liner is wanted porous steam usually, can breathe freely.This waterproof plug-in unit is called functional layer or functional material sometimes.Can constitute by following material: an a) one functional layer only, or b) comprise the material that the two-layer laminate thing of functional layer material and cloth lining or fabric liner constitutes, or c) trilaminate material that constitutes of functional layer material, inner textile layer and fabric liner.Comfortable for reaching dermal sensation, in the plug-in unit the inside the coherent cloth lining of one deck is arranged, perhaps the interior tissue layer of sandwich is made by lining material.For easily manufactured and cost is low, these plug-in units usually by two relatively and the functional layer of same shape size or sandwich plain film along the edge sealing and constitute.The figure of plain film has the two-dimensional shape above the hand size.
Known have gloves that comprise shell and contain the functional layer plug-in unit.Its two-dimensional shape of described plug-in unit want to pack into 3D shape of gloves shell will certainly produce some folds.Under the thermal glove situation, this only is a problem of smaller, because increased heat insulating material formedly between functional plug-in unit and thick cloth lining in this case, can make the imperceptible fold of glove people.
Under thin non-thermal glove situation, because gloves are made very near the shape of hand, the fold of plug-in unit can produce very big shortcoming.Wearer can feel that these make us uncomfortable fold.Again can not be fixed to one another between the fold, therefore, hand has sliding phenomenon in gloves, may cause the harm to wearer in the activity that needs good grip.And fold has increased thickness thereby has reduced sense of touch, and sense of touch is very important to the activity of the trickle sensation of needs.Fold has also increased the resistance to heat transmission and moisture transfer, and this is bad under warm environmental condition.The example of gloves has work gloves, motorcycle gloves and glove for golf like this.
Many effort have been paid for overcoming these defectives people.An example is US 5,4442,818, and inside is that the plug-in unit that bidimensional that lining and the sandwich of three-dimensional constitutes is folded into sticks with glue agent and combines with " anti-skidding " form, therefore obtains inner gloves for three-dimensional.The fold of the bidimensional plug-in unit between cloth lining and the shell can be tolerated owing to be coated over the stitching lining back of three-dimensional.Yet it is huge and to the high-drag problem of heat transmission and moisture transfer that this system fails to solve gloves.This is because the result of the multilayer that the plug-in unit fold that still exists causes.
US 5,255, and 716 is another patent, and this patent has been described a kind of two layers of material, promptly are bonded in second wrinkle functional layer or the barrier layer that can expand on the tissue layer, and this two layers of material sticks with glue agent then and is fixed on and can expands on the outer tissue layer.At US 5,255, in 617, this kind tissue layer is stretchable, and its bonding mode can cause the gathering of functional layer.This causes the unnecessary thickness of composite bed that forms.Therefore, the resistance of heat transmission and moisture transfer is failed to reduce to minimum.Increased warming value as its advantage even address in this patent, this advantage also only just needs (the 13rd page, 28 row) when requiring gloves to need thermal property.The thickness of plicated layer adds that the elasticity of fold has significantly reduced sense of touch.
US 5,255, and 617 have proposed the non-resilient gloves shell made by for example leather.Yet, can not make such gloves according to described method, because its shell must be on a flat bidimensional template tractive, forming mode requires shell to have great elasticity, can cooperate the finger part (the 47th page of the 3rd row) that is broad because the opening of gloves must be able to be stretched to.This is the problem that this method is difficult to avoid itself, variation by flat bidimensional template can not solve, because the periphery that finger increases is than the Zhou Bianchang of palm area hand, so template is wider than palm area all the time at finger part, so that stretch whole gloves fully, this is essential in described method, can be on full surface bonding gloves.
US 5,740,551 disclose a kind of multilayer gloves, comprise the shell that constitutes by the knit materials that allows fully to stretch, cotton internal layer plug-in unit that its size is matched with the wearer's hand size and be clipped in the bigger intermediate barrier plug-in unit of size between aforementioned two, this plug-in unit has gas-permeable, the impermeable functional layer of liquid.Use an artificial hand to be used for the assembling of gloves.At first, plug-in part is placed on the artificial hand, next with the block interposer lies on the plug-in part on the artificial hand.The shell that stretches at last, before it is enclosed within two-layer on.Take off this gloves that are assembled into from the artificial hand then and carry out hot pressing.The heat of compacting usefulness and pressure make and are provided at the lip-deep sandwich material fusing that can melt again of block plug-in unit and bonding with the shell and the plug-in part of gloves.Because the over dimensioning of block plug-in unit, shell are stretched on the block plug-in unit on the artificial hand and during the gloves of compacting assembling, fold and clustering phenomena take place probably.
Summary of the invention
The present invention has overcome the defective of prior art, especially in order to make complete assembled glove thickness reach minimum, thereby the sense of touch of making, grasping, ventilative, heat transmission and flexibility the best, and the Handcovering of broad sense is provided, it comprises: inelastic substantially cladding material partly is that shell (as being made of leather or woven fabric) and the inner layer material that is bonded on the shell partly are the gloves plug-in part.The gloves plug-in part comprises that can make water vapor permeable but the functional layer of waterproof, and this plug-in part can not produce fold substantially on whole gloves, its functional layer substantially not can, better be the phenomenon that does not have gathering fully.
The invention provides a kind of Handcovering that cladding material part and inner layer material part are arranged, inner layer material part wherein is made of stretchable sandwich, and this sandwich comprises the water-proof function layer and the tissue layer of porous steam, and comprises outer surface; Cladding material partly has 3D shape and the corresponding three-dimensional inner surface that accords with hand; The inner layer material part is stretched to the three-dimensional inner surface of cladding material part in this manner, and basic all outer surfaces of inner layer material part are fitted on the inner surface of cladding material part; Almost whole outer surfaces of inner layer material part are adhered on whole inner surfaces of cladding material part basically; Cladding material part is made of essentially no flexible cladding material, and this material can absorb because of partly the stretch restoring force of the sandwich that causes of inner layer material.
The present invention also provides the method that cladding material part and inner layer material Handcovering are partly arranged of making, and this method comprises the following steps: to make has the 3D shape that accords with hand and the cladding material part of corresponding three-dimensional inner surface; Manufacturing is can the stretch inner layer material part of sandwich of bidimensional, and described sandwich has the water-proof function layer and the tissue layer of permeable steam, and has outer surface; The inner layer material part is stretched to the three-dimensional inner surface of cladding material part in this manner, and basic all outer surfaces of inner layer material part are fitted on the inner surface of cladding material part; Almost whole outer surfaces of inner layer material part are adhered on whole inner surfaces of cladding material part basically; Cladding material part is made of essentially no flexible cladding material, and this material can absorb because of partly the stretch restoring force of the sandwich that causes of inner layer material.
Provide functional layer such as porous PTEF film and the sandwich that is layered in the cloth lining on this film to make Handcovering, should handle with polyurethane non-porous but that allow hydrone to pass through on the surface of functional layer.This sandwich can also have the textile protection backing.Sandwich is stretchable to a greater size.Cloth lining and protectiveness backing can be any fabric or the expanded material that constitutes as polyurethane or polyester.Cloth lining and protectiveness backing better are layer knitted fabrics.Cloth lining and fabric liner can be made of PET, polyamide, viscose glue, cotton or these mixtures of material.
For forming plug-in unit, two described sandwich are stacked, press then boxing glove or ordinary glove the appearance profile linear sealing it, along this outline line periphery cutting, formation Handcovering plug-in unit.It is littler that its shape can size in some zone of hand.
On two outer surfaces of this plug-in unit, apply adhesive.The mode that adhesive can be put, netted mode or apply continuously.Also can before the good seal plug-in unit, on sandwich, apply adhesive.
Then, interposer lies applies heat in the inside of shell by the thumb template of heating and four finger fingerprint plates of heating, makes adhesive plug-in unit is bonded in the inside of shell.Generally, preferably at first heat the thumb part, plug-in unit and shell are fixed on correct each other position, the slip when preventing to carry out this step.Because the 3D shape of shell, plug-in unit is stretched in some zone, meets with the 3D shape of shell, then the plug-in unit of bidimensional is shaped as again the 3D shape of shell, and do not form fold this moment substantially, and then, plug-in unit is adhered on the shell of gloves with such shape.Reach on the total inner surface initial bonding after, to the inner bubbling air of plug-in unit, purpose is a) plug-in unit to be pressed on the shell securely, b) the cooling adhesive c) takes off gloves from the hand shape template of heating, does not have much frictions this moment.
In the embodiment of the present invention, Handcovering is that the hand wear is the form of ordinary glove or boxing glove.
In the embodiment of the present invention, Handcovering is that the hand wear is warming ordinary glove or boxing glove form, perhaps Bao non-warming ordinary glove form.
The detailed description of embodiment of the present invention
As mentioned above, the cladding material shell of hand wear is directly bonding in this manner with the plug-in unit that comprises functional layer, promptly this moment the plug-in unit stretching of bidimensional is shaped as the 3D shape of shell again, so has avoided fold and clustering phenomena.A kind of Handcovering that can overcome above-mentioned prior art defective so just is provided.
Direct bonding formation ordinary glove of the outer surface of described shell and functional layer plug-in unit or boxing glove prevented the existence of air layer, and air layer can play water vapor barrier between shell and the functional layer plug-in unit.And the number of plies can be guaranteed the thermal insulation and the maximum dexterity of hand wear minimum as far as possible less.For this reason and better draftability is promptly extended, and functional layer can be directly bonded on the shell material and the fabric liner that need not protect.The composite bed of the whole gloves of the present invention comprises common outer shell, adhesive and functional plug-in unit sandwich layer, and the steam penetration resistance Ret of whole composite bed is less than 35 (m
2* Pa)/and W, in embodiment preferably even less than 15 (m
2* Pa)/and W, look the selection of cladding material and lining material and different.
The bonding of shell and plug-in unit can promptly apply adhesive with conitnuous forms on entire area, perhaps applying promptly with discontinuous form does not have adhesive on>50% surface area.In this respect, adhesive can be applied on the outer surface of plug-in unit easily.Adopting the situation that applies adhesive layer continuously, use can be permeated the adhesive of steam.If use discrete adhesive layer, for example the form with powder, point, grid or net applies adhesive, can use the adhesive of impermeable steam.Be the permeability that keeps steam by the plug-in area of rubber cover stick not at this moment.
The shell that is suitable for ordinary glove of the present invention or boxing glove can be for example leather or textile material.Fabric can be for example woven fabric, knitted fabric, supatex fabric or felted terxture.These fabrics can by natural fiber for example cotton or viscose glue form, or form by synthetic fibers such as polyester, polyamide, polypropylene or polyolefin, perhaps the mixture by at least two kinds of above-mentioned materials forms.Such cladding material is water and water vapor permeable normally.The water proofing property of cladding material is provided, can makes it become repellency, make the hole of cladding material keep opening wide transmitting steam with the hydrophobic material shell.
Adhesive should be thermal activation, adhesive is selected from the adhesive of copolyamide, copolyester, PAUR, polyolefin, polyamide or polyurethane preferably, for example reactive polyurethane adhesive, also can be the mixture of polyester-type urethanes and polyurethane.The adhesive fusing point can be 50-130 ℃ of scope.
Functional material can be material such as porous polyethylene, the polyurethane etc. that can breathe freely of any waterproof.Being preferably the porous Teflon layer is adhered at the sandwich of feeling on the skin on the comfortable cloth lining.Porous Teflon better is according to US 3,953, and the expanded polytetrafluoroethyl(ne of 566 described preparations is though better have the non-porous polyurethane coating that can transfer vapour molecule by the molecule transmission.Such bond is described in US4, and 194,041.This bond is bonded in the suitable fabric layer that is used to protect the porous Teflon layer.
Plug-in unit is packed in the shell can prevent that functional layer from contracting wrinkle and the mode of assembling is carried out.The sandwich that makes must have at least one direction at least 30%, is preferably 40% tensility, so that sandwich is stretched to the 3D shape that accords with hand.On both direction, all have tensility and be advisable greater than 40%.Sandwich must still keep its water proofing property and water vapor permeable by the state after stretching.For keeping plug-in unit stretched and to be adhered to the deformation force of shell little, the stress-strain diagram of sandwich must be smooth (to the 30% elongation<30N/5cm (is the sample of 5cm for width) of at least one direction).Sandwich is preferably low restorative.Figure 11 shows that from the GORE-TEX of length (point direction longitudinally perpendicular to plug-in unit) 20cm and wide 5cm
The stress-strain characteristics of the sample that plug-in unit cuts out, this plug-in unit comprise the tissue layer of ePTFE (polytetrafluoroethylene (PTFE) of expansion) layer and multifilament polyester knitted.The weight of insert material is 100g/m
2, its tissue layer weight is 70g/m
2This sample is a stress application in the vertical.
As previously described, shell is made of inelastic substantially cladding material, and this material can absorb the restoring force of the sandwich that causes because of the plug-in unit stretching.Whether the cladding material that is easy to test Handcovering of the present invention has absorbed restoring force, and method is: the Handcovering of making is heated to the adhesive liquefaction that plug-in unit is adhered to shell.If plug-in unit separates with shell when adhesive liquefies, shell has just absorbed restoring force.Finger root at Handcovering is awared this separation especially easily with dorsal surface of thumb, because the most different with the two-dimensional shape of the plug-in unit that do not stretch in the 3D shape of these regional Handcoverings.
As shown in Figure 1, actual way is that two sandwich 11 are stacked together, and draws figure 10 by the shape of hand then so that form plug-in unit.These two figures along periphery shown in Figure 2 20 sealings, stay the opening 21 that is used to insert staff then.By applying adhesive, heat and exerting pressure, seal at the graph outline edge.Press the part that the figure on the sandwich downcuts good seal afterwards.Suitable adhesive comprises IPATHERM adhesive, ETANE, TEXIN, PELLETHANE or the MORTHANE adhesive that derives from H.B.Fuller.Representational adhesive comprises co-polyethylene terephthalate, copolyamide or polyurethane.
According to top described, the plug-in unit of formation sticks with glue agent and handles on two outer surface, plug-in unit is inserted in the shell treating.As shown in Figure 3, adhesive is to apply on plug-in unit 31 surfaces, is the point 30 of many projectioies.Then, plug-in unit is moved in the shell 32 according to the direction of arrow.
Adhesive is heat-activatable, can directly heat, or activate with microwave or infrared ray.
Figure 4 shows that the profile of the Handcovering of making that comprises shell 40 and plug-in unit 41, promptly shell 40 and plug-in unit 41 illustrate with " profile ".Certainly, plug-in unit is actually and is bonded in shell.Among Fig. 4, shown in plug-in unit 41 comprise functional layer 42, tissue layer 43 and seam 44, seam mouth 44 is connected by suture 45 by two adjacent shell sheets (being designated as 44) and forms.Shown in the figure 46 is for being used for the dots of adhesive of bonding shell and plug-in unit.In fact, in final products, the inner surface of plug-in unit outer surface next-door neighbour shell, very close to each other between shell and the plug-in unit.In other words, the dots of adhesive of protruding among Fig. 4 will become smooth in final products.
Figure 5 shows that shell 50 and plug-in unit 52.Plug-in unit 52 is in the state that will insert in the shell 50.In this embodiment, adhesive is applied on the outer surface of plug-in unit 52 with grid form.
Shell 50 comprises the long body 54 of shell, the thumb 56 of shell and the finger 58 of shell.Shell 50 has 3D shape.Plug-in unit 52 comprises the long body 60 of plug-in unit, the thumb 62 of plug-in unit and the finger 64 of plug-in unit.Insert before the shell 50, plug-in unit 52 is a two-dimensional shape.
There is not adhesive on the long body 60 of plug-in unit, therefore not combination of long body 54 and 60 by adhesive.
The present invention in embodiment, is by three-dimensional heated die plate preferably, better is rigidity, and preferably metal template applies the heat of activation adhesive.First template 66 shown in Figure 6 has the thumb part 68 of thumb shape, and second template 70 shown in Figure 7 has the finger part 71 of four finger hand shapes except that thumb.In the boxing glove situation, the finger-type shape of selling needn't be shaped.The gloves that template 66 and 70 size must and be made match.Template must be divided into thumb part and these two parts of remainder, only in this way the shell of gloves could be enclosed within on the close-fitting like this template, because the gloves shell does not have elasticity or elasticity very poor.
In first number of assembling steps, plug-in unit 52 is placed in the gloves shell 50, makes all fingers 64 of plug-in unit be in the respective finger 58 of shell 50.Shell 50 and plug-in unit 52 are pulled in two templates 66 and 70 together in regular turn, promptly on thumb template 66 and the four fingerprint plates 70 that refer to.Should be at first bonding and the fixing zone of thumb, so that plug-in unit 52 and shell 50 are an integral body in later step.Remainder to this assembly applies heat then, and plug-in unit 52 entirely is adhered on the shell 50.By the slightly little but stretchable plug-in unit 52 of size is moved on template 66 and 70, the plug-in unit 52 of bidimensional just stretches and becomes the 3D shape of template 66 and 70, and is adhered on the gloves shell 50 with this shape.Because gloves shell 50 closely is enclosed within on template 66 and 70, plug-in unit 52 just is the basic configuration of gloves at this moment and is fixed therein.
But the air supply pipe 75 and 77 that switch is arranged respectively on these two templates.After adhesive 53 had activated, the adhesive 53 of bubbling air cooling activation forced plug-in unit 52 to be close to shell 50 and makes its shape that accurately is shell 50, and friction is not taken off gloves 72 from template 66 and 70 in ground down.Use has the sandwich of smooth stress-strain diagram, specially designed plug-in unit figure and up to the pressure of 0.3 crust, can reach the distortion of plug-in unit 52, makes plug-in unit 52 fixing and substantially wrinkle-free generation gloves shell 50 in.Final owing to the restoring force that plug-in unit 52 can be withdrawn into its original form is absorbed by gloves shell 50, plug-in unit 52 just can keep the 3D shape of gloves 72 always.
In one embodiment of the invention, template 66 and 70 comprises electric connection 78 and 80 respectively, and for electrical heating elements 82 and 84 is carried heating-supplied electric energy, they are contained on template 66 and 70 or wherein separately.
In this way, just can make the incorporate Handcovering that its plug-in unit 52 or functional layer substantially wrinkle-free do not have clustering phenomena yet.
Figure 8 shows that the gloves of making, wherein a part is a profile, exposes the inside of gloves 72, i.e. the finger part 64 of plug-in unit, the discontinuous adhesive 53 on plug-in unit 52 outer surfaces and the shell 50 of gloves 72 of being applied to.Can clearly be seen that by Fig. 8, the adhesive that applies by point-like in the embodiment illustrated, the finger part of shell 50 and plug-in unit 52 and the part of hand all are bonded together securely, and the long body 54 of shell and the long body 60 of plug-in unit are then loose each other to be contacted.
Figure 9 shows that along the sectional view of the finger of glove part 73 of IX-IX line among Fig. 8.The shell of finger of glove 73 finger 58 is connected to form by seam 75 by four sheathing materials 74.The plug-in unit of finger of glove 73 finger 64 is made of two sandwich 11 (Fig. 1), and sandwich 11 comprises functional layer 42 and tissue layer 43, by abutment joint 76 (among Fig. 2 20) along the sealing of finger periphery.The sandwich material extending that is originally bidimensional with plug-in unit finger 64 becomes three-dimensional shell to point 58 shape then, and be adhered on the inner surface of shell finger 58 by the outer surface of adhesive 53 with plug-in unit finger 64, plug-in unit finger 64 just keeps the 3D shape of shell finger 58, therefore, plug-in unit finger 64 just can keep substantially wrinkle-free.
Show that with regard to gloves finger 73 content of also above-mentioned explanation also is applicable to all parts of gloves 72 in Fig. 9, wherein plug-in unit 52 has stretched and has been adhered to three-dimensional case 50.
Figure 10 is the layer structure by the gloves of making 72 shown in the cross section amplifier section of circle X among Fig. 9.As shown in figure 10, the plug-in unit 52 that comprises functional layer 42 and tissue layer 43 is adhered on the shell 50 by adhesive 53.
