[technical field]
The present invention relates to a kind of underwear and cup bra, more specifically a kind of high ventilative foamed silica gel underwear and cup bra.
[background technology]
Underwear and cup bra conventional currently on the market is use polyurethane foam material (PU sponge) to manufacture mostly; but the main raw material(s) TDI (toluene di-isocyanate(TDI)) inside sponge is but toxic chemical; and sponge foaming process also to add a lot of not environmentally chemical substance such as foaming agent, antioxidant; other non-environmental protection chemicals of the trace TDI volatile matter that sponge cup dissipates out and residual; easily absorbed through mammary gland, skin pore by breast; so PU sponge cup life-time service, the health of the serious threat mankind.
Present underwear industry is all finding a kind of environmental protection underwear and cup bra that can substitute sponge, existing producer uses the Polyester Fibers of environment-protecting asepsis to manufacture underwear and cup bra, because polyester fiber has environment-protecting asepsis, and the features such as good permeability, such polyester fiber cup is being started selling at present on the market.But use the underwear and cup bra that polyester fiber is suppressed to be easily deformed after washing, can cause that cup sizes change and supporting force decline, it is impossible to long-term normal use.In order to reach the defect covering cup deformation and supporting force decline, it is very thick that the cup of polyester fiber compacting does, general thickness reaches more than 12mm, deformation and the deficiency of supporting force decline is covered by the thickness of cup, but blocked up underwear and cup bra weight is big, wearing comfort reduces, and cost is also higher, therefore promoting the use of of polyester fiber underwear and cup bra exists great limitation.Currently also have tried to make cup by the foamed silica gel of environment-protecting asepsis, but foamed silica gel breathability is very poor, use the produced foamed silica gel cup poor air permeability of material and technology of existing underwear and cup bra, it is not easy heat radiation, particularly in hot summer or after exercise, can cause that women cover cup temperature is also higher 2~5 degree than existing sponge cover cup temperature, and sweat cannot discharge in time, cause cup inner product antiperspirant, moist, it is difficult to dry and comfortable.
Therefore, the present invention is based on above deficiency and produces.

[detailed description of the invention]
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the radiating mode schematic diagram of general sponge cup in prior art, and what in figure, arrow illustrated heat distributes direction.The ventilative heat radiation of existing conventional sponges cup is all the breathability by cup material, allows heat that female chest the produces inner layer cloth by cup, through cup inner support material, finally inside and outside ventilative with heat radiation then through the carrying out of outer layer cloth.But health is had harm by other non-environmental protection chemicals of the trace TDI volatile matter that sponge cup dissipates out and residual.Therefore, sponge cup needs to be eliminated.
Fig. 2 is the radiating mode schematic diagram of foamed silica gel cup in prior art, and what in figure, arrow illustrated heat distributes direction.Foamed silica gel possesses good flexibility and resilience, and environment-protecting asepsis, it it is extraordinary cup inner support material, but it is bad that its distinct disadvantage is breathability, the direction of arrow from figure is it can be seen that partial heat is through foamed silica gel cup, but partial heat is returned and can not distribute, so the breathability of foamed silica gel is very poor, yet suffer from very big deficiency as underwear and cup bra.Even if foamed silica gel being used the method punching of physics punching, also because female breast is soft, hole is easy to be covered by breast, and physics punching number is limited after all, ventilative radiating effect is inconspicuous, comfortableness declines a lot compared with general sponge underwear and cup bra, and foamed silica gel cup cannot be esthetically acceptable to the consumers at present.
Fig. 3 is the ventilative foamed silica gel underwear and cup bra schematic diagram of one height of the present invention, and what in figure, arrow illustrated heat distributes direction.A kind of high ventilative foamed silica gel underwear and cup bra of the present invention includes the cup body 1 being made up of foamed silica gel, described cup body 1 is included clothing the cup medial surface 11 near skin of breast and the lateral surface 12 away from skin of breast when wearing, described medial surface 11 is provided with air-permeable layer 2, and the Ventilate cloth that described air-permeable layer 2 is thick for 1.5mm to 7mm is constituted.Described cup body 1 is provided with multiple ventilative through hole 6.Owing to being provided with air-permeable layer 2 between foamed silica gel cup body 1 and skin of breast, so through hole 6 will not be blocked by skin of breast, heat can pass through air-permeable layer 2, excretes rapidly then through through hole 6, and the breathability making underwear and cup bra to a certain extent is better.Although foamed silica gel cup body 1 breathability providing support force and resilience force is poor, but the Ventilate cloth of 1.5mm to the 7mm thickness inside cup body 1 so that the heat of breast distributes along air-permeable layer 2 towards surrounding more, can greatly strengthen breathability.And the thickness of Ventilate cloth is 1.5mm to 7mm, also the more excellent performance of underwear and cup bra is made, if the thickness of Ventilate cloth is less than 1.5mm, skin of breast and underwear and cup bra still can paste very tight, the effect that heat distributes along Ventilate cloth towards surrounding is excessively poor, if cup body 1 is provided with through hole, and Ventilate cloth thickness is then still likely to the through hole that closure is ventilative less than 1.5mm, do not have good air permeable effect, so only Ventilate cloth thickness more than 1.5mm time could allow heat flow, the hole then passing through Ventilate cloth sheds, therefore, the advantage that underwear and cup bra of the present invention had both embodied foamed silica gel, the perfect foamed silica gel cup that solves is breathed freely the problem of heat radiation again.If additionally the thickness of Ventilate cloth is more than 7mm, the comfortableness of underwear and cup bra reduces, owing to Ventilate cloth is softer, if Ventilate cloth is very thick, passive foamed silica gel cup body 1 is farther apart with breast, and the support support effect that cup body 1 is played will be had a greatly reduced quality, say, that when thicker with the Ventilate cloth of breast contact, Ventilate cloth is difficult to breast is provided bigger support force, long periods of wear can cause the deformation of breast, thus not having the due function of underwear and cup bra.
As shown in Figure 3, Figure 4, described air-permeable layer 2 is by the sandwich fabric of Polyester Fibers braiding.Described air-permeable layer 2 thickness is 1.5mm to 5mm.The sandwich fabric of Polyester Fibers braiding is made up of upper strata 71, intermediate layer 72,73 3 layers of lower floor.Upper strata 71 is generally mesh design, and intermediate layer 72 is the supporting layer erectting braiding, and lower floor 73 is generally the close lithographic plate face knitted.Therefore, the sandwich fabric of Polyester Fibers braiding is three-layer stereo ventilating structure, and the heat of breast enters into the intermediate layer 72 erectting braiding by the upper strata 71 of mesh, then distributes from intermediate layer 72 to surrounding, and permeability is excellent.And sandwich fabric thickness is 1.5mm to 5mm, because sandwich fabric possesses well very property, when whole underwear and cup bra pressurized, what first deform is that the cup body 1 that foamed silica gel is made produces deformation, and the integral thickness of sandwich fabric will not be subject to compression thinning, therefore, the breathability of air-permeable layer 2 entirety remains unchanged, but when the thickness of sandwich fabric is lower than 1.5mm, sandwich fabric is too thin, although heat can distribute along the surrounding of sandwich fabric, but the effect distributed is still undesirable, breathability is still poor, but when the thickness of sandwich fabric is more than 5mm, the braiding supporting layer erect because of sandwich fabric intermediate layer 72 is too high, sensation of significantly tumbling is had when pressing, sense of touch is bad, affect the comfortableness that underwear and cup bra is worn.So sandwich fabric thickness is set to 1.5mm to 5mm optimum.
As it is shown on figure 3, be provided with solvent-free additional organosilicon binding agent between described air-permeable layer 2 and cup body 1 and the two the first tack coat 3 bonding.The bonding of current conventional underwear cup cloth and supporter is generally adopted the liquid silica gel binding agent etc. of PUR hot pressing laminating, condensed type organic silicon binding agent and peroxide cure, these bonding modes or easily delamination and cannot bond, efficiency is low, there are obvious tart flavour or alcohol taste, not environmentally.And adopting solvent-free additional organosilicon binding agent between air-permeable layer 2 of the present invention and cup body 1, high temperature speed is fast, and efficiency is high, is firmly bonded, and bond effect is good, nonpoisonous and tasteless environmental protection.
As it is shown on figure 3, be additionally provided with outer layer cloth 4 on described lateral surface 12, cup body 1 is coated with by described air-permeable layer 2 and outer layer cloth 4.
As it is shown on figure 3, be provided with solvent-free additional organosilicon binding agent between described outer layer cloth 4 and cup body 1 and the two the second tack coat 5 bonding.
(breathability test philosophy: air is vertically through fabric is tested by breathability, positive and negative at fabric forms certain pressure reduction, measure the air capacity through fabric in a certain pressure reduction lower unit interval, it is the air penetrability of this fabric), the performance comparison such as following table of underwear and cup bra in underwear and cup bra of the present invention and prior art:
As can be seen from the above table, underwear and cup bra of the present invention selects polyester fiber sandwich fabric thick for 1.5mm to 5mm in air-permeable layer 2, and combination property when cup body 1 gets through hole 6 is classic.
