Description
The application requires the priority of on October 11st, 2007 at the patent application No.2007-265677 of Japan's submission, and its full content is incorporated herein with for referencial use.
Technical field
The fibre that the present invention relates to a kind of three-dimensional warp-knitted fabric and form by this three-dimensional warp-knitted fabric.The invention particularly relates to a kind of three-dimensional warp-knitted fabric that has better gas permeability and sense of touch and can keep its outstanding damping characteristics, thickness retention performance and shape stability, and the fibre of forming by this three-dimensional warp-knitted fabric.
Background technology
Polyurethane foam, non-woven fiber and analog have been used as the material that is used for brassiere cup and analog.
Though polyurethane foam have outstanding for washing durability and for the recovery and the durability of compression, the polyurethane foam air permeability is lower.Therefore, when the user dressed the brassiere made by polyurethane foam or analog, polyurethane foam can cause because perspiration produces phenomenon soaked with sweat.The light resistance of polyurethane foam is relatively poor.Therefore, brassiere cup or the analog made by polyurethane foam damage easily, that is to say, because of being exposed to flavescence in the ultraviolet ray.
On the other hand, though non-woven fiber has outstanding gas permeability, thereby it is at the recovery in when compression with durability is poorer loses shape easily.
In recent years, have and organize two-layerly and make the three-dimensional warp-knitted fabric of organizing interconnected connecting line to begin to be used for various fields two-layerly owing to its outstanding resistance to compression and damping characteristics.Three-dimensional warp-knitted fabric is widely used in business suit, sportswear, underwear etc. at garment industry, and is widely used in interior decoration material etc. in the material field.Three-dimensional warp-knitted fabric is because its outstanding shape stability and the durability when washing attract people used as the brassiere cup material.
Figure 9 shows that the schematic cross-section of three-dimensional warp-knitted fabric 1 along its warp-wise, each ring of connecting line 4 and the first ground tissue 2 and second ground organize 3 corresponding rings to link to each other.That is, the first ground tissue and the second ground tissue are made up of with the weaving thread that the knitting needle number equates quantity, and link to each other with all ring of the first ground tissue 2 with the second ground tissue 3 corresponding to the connecting line 4 of knitting needle.By the angle (referring to Figure 10) between change connecting line 4 and the first ground tissue 2 and the second ground tissue 3 and the fineness of connecting line 4, can improve the thickness retention performance and the buffering characteristic of three-dimensional warp-knitted fabric 1.
Three-dimensional its sense of touch of warp-knitted fabric is harder relatively.In order to improve its damping characteristics, in known technology, used individual filament as connecting line.But, expose in gap that individual filament can exist from the ground tissue of three-dimensional warp-knitted fabric and the sutured portion in this case, when when three-dimensional warp-knitted fabric is exerted pressure.Therefore, when three-dimensional warp-knitted fabric is used as the material that is used for underskirt, Diazolidinyl Urea, thus the user is felt under the weather.Use therein in the three-dimensional warp-knitted fabric of individual filament, can't fully circulate at itself and user's the contacted position of skin air.Therefore can't fully solve problem soaked with sweat.
In order to prevent from wherein to have used the three-dimensional warp-knitted fabric chafe of individual filament, as described in Japanese patent application No.2000-160459 (patent documentation 1), a kind of three-dimensional warp-knitted fabric that has wherein used many filaments has been proposed.
But individual filament is softer.Therefore, the damping characteristics of three-dimensional warp-knitted fabric and thickness retention performance worsen easily.In order to keep its damping characteristics and thickness retention performance, the method for having taked to increase the fineness of connecting line and increase connecting line quantity is to increase the hardness of connecting line.But organize interconnected connecting line owing to used with making in a large number, these methods can cause the quality of three-dimensional warp-knitted fabric of per unit area heavier, and the gap between the connecting line is less, therefore can make the gas permeability variation of three-dimensional warp-knitted fabric, and make fabric harder.
As described in Japanese patent application No.11-200106 (patent documentation 2), the brassiere cup of being made up of three-dimensional warp-knitted fabric has been proposed.Cellulosic long fiber is used as the line of a face (upper surface or lower surface) of fabric of a side that is used for three-dimensional warp-knitted fabric contact skin to suppress sensation soaked with sweat.
But when the amount of dressing this brassiere perspiration was big, this structure can not suppress sensation soaked with sweat.Another problem of this brassiere is the increase along with washing times, and the sense of touch of brassiere changes.

Summary of the invention
Consider that the problems referred to above have carried out the present invention.Therefore, first purpose of the present invention is to provide a kind of three-dimensional warp-knitted fabric, this three-dimensional warp-knitted fabric has higher air permeability suppressing sensation soaked with sweat, and can not reduce its outstanding damping characteristics, thickness retention performance and shape stability, and has better sense of touch.
Second purpose of the present invention is to provide a kind of fibre of being made by this three-dimensional warp-knitted fabric, for example contacts the brassiere cup and the analog of skin, so this cup and analog are felt well the user when dressing this fibre.
In order to address the above problem, first invention provides a kind of three-dimensional warp-knitted fabric, and its structure is along in the cross section of broadwise, and the connecting line that tilts with the surface of the first ground tissue and the second ground tissue is connected to each other the first ground tissue and the second ground tissue.In this structure, the first ground tissue has the ring that is not connected with connecting line with predetermined interval, and each ring of the second ground tissue all links to each other with a connecting line respectively.
As mentioned above, because connecting line is connected with each ring of the second ground tissue, so its linking number is identical with traditional three-dimensional warp-knitted fabric in the quantity of connecting line and the second ground tissue.But the first ground tissue has the ring that does not link to each other with connecting line.Therefore, in the first ground tissue, each ring that will be connected with connecting line has all connected and has been no less than two connecting lines.That is, connecting line is organized into first ground along its broadwise with different angles and organizes braiding obliquely from second ground.For example, when the first ground tissue is constructed such that its ring that links to each other with connecting line distributes with the central spacer that do not link to each other with connecting line, respectively with the second ground tissue in one encircle two connecting lines that are connected and link to each other with a ring of the first ground tissue.Therefore, connecting line links to each other with the ring of the first ground tissue and the ring of the second ground tissue, thereby formed subtriangularly betwixt, this triangle has the approximate inverted triangle space that the connecting line that be arranged in parallel along broadwise and the position with the ring that is not connected with connecting line in the first ground tissue form.
By foregoing description as can be seen, in the structure of first invention, the first ground tissue has the ring that does not link to each other with connecting line.Therefore, the structure of first invention can make the air permeability of the air permeability second ground tissue of the first ground tissue compare and be improved, and make between the adjacent connecting line the gap greater than all rings of all rings of the first ground tissue wherein and the second ground tissue respectively with traditional structure that connecting line is connected in adjacent connecting line between the gap, be improved thereby air permeability between the connecting line in air permeability and the traditional structure between the connecting line is compared.Therefore, the structure of first invention can make the gas permeability of whole three-dimensional warp-knitted fabric compare with the gas permeability of the three-dimensional warp-knitted fabric of traditional structure to be improved.Therefore, can be the rapidly dry moisture of perspiring and being produced of the three-dimensional warp-knitted fabric of first invention, thus alleviate sensation soaked with sweat and that adhere to.
Connecting line links to each other with the ring of the first ground tissue and the ring of the second ground tissue, between the first ground tissue and the second ground tissue, to form subtriangular space, and the space of the approximate trapezoid between adjacent triangle space, thereby make the first ground tissue and the second ground tissue be difficult to move, thereby make three-dimensional warp-knitted fabric keep its outstanding shape stability, thickness retention performance and buffering characteristic along broadwise.Therefore, gas permeability is used to brassiere cup and analog, sportswear, footwear, indoor decoration, reaches analog with the material that cushions characteristic three-dimensional warp-knitted fabric as having preferably.
In the first ground tissue, the ring that links to each other with connecting line is not less than the ring that links to each other with connecting line.Therefore, first ground with big or small ring organizes its gas permeability to be higher than the gas permeability of the second ground tissue.
Quantity with the ring that links to each other with connecting line organizes its sense of touch to organize softer than second ground less than first ground of the second ground tissue.
When the three-dimensional warp-knitted fabric that uses its first ground tissue to be arranged on skin one side is made fibre, can prevent to produce and swelter and make the user when this fibre of wearing, feel more comfortable.
Thereby weaving at all stitch places along its broadwise, the first ground tissue that preferably links to each other with connecting line and the second ground tissue have above-mentioned ring.Suppose that on the broadwise of the second ground tissue ring of the second ground tissue and the ratio of the braiding between the connecting line were set as at 100% o'clock, on the broadwise of the first ground tissue, the ring of the first ground tissue and the braiding between the connecting line are than preferably being set as 30～75%.The transverse width of the connecting line in the preferred first ground tissue is set as 1～6 stitch, and on the broadwise of the first ground tissue, the preferred first ground tissue links to each other with connecting line with the interval of 1～6 ring.
That is, preferably the Connection Density of the connecting line in the first ground tissue is made as 30～75%.If its Connection Density is less than 30%, so three-dimensional warp-knitted fabric may not have sufficient shape stability and buffering characteristic.On the other hand, if its Connection Density greater than 75%, its density is higher so.So, between adjacent connecting line, can't form sufficient enough big gaps, so three-dimensional warp-knitted fabric may have relatively poor gas permeability.
Preferably in the first ground tissue, the transverse width of connecting line is made as 1～6 stitch, and settles connecting line that connecting line is linked to each other with the first ground tissue with the interval of 1～6 ring by broadwise along the first ground tissue.
Transverse width be meant when warp knitting machine knit reed along a row through compiling pin (between knitting needle) when mobile, warp knitting machine knit reed to its knitting needle number that moves or warp knitting machine knit reed to its move through the number of turns.A stitch in the transverse width is meant that connecting line is organized into the second ground tissue along first ground direction organizes straight line (non-inclination) to be connected with the first ground tissue and second ground, as shown in Figure 2.
The transverse width of connecting line is set as 1～6 stitch, and this is because if transverse width greater than 6 stitch, then is difficult to weave three-dimensional warp-knitted fabric, and the quality of the fabric of per unit area can become big.
As for transverse width, preferably the interval between the ring of the first ground tissue that will link to each other with connecting line is set as 1～6.By the interval between the ring of widening the first ground tissue, can strengthen the gas permeability of three-dimensional warp-knitted fabric.If but the interval between the ring is not less than 6, then is difficult to weave this three-dimensional warp-knitted fabric, and be difficult to make this three-dimensional warp-knitted fabric to have sufficient shape stability and buffering characteristic.
As for being used to the fiber that is used to form three-dimensional warp-knitted fabric of the present invention, what can exemplify has for example polyethylene terephthalate, polyamide fiber nylon, regenerated fiber cellulose, a natural fabric blended fiber of cotton, silk and wool, these fibers for example for example for example of polyester fiber.Consider to the plasticity that heats and compress, resistance to compression, washing resistance, elasticity etc., preferably by containing the fibrous three-dimensional warp-knitted fabric of polyester fiber as its key component.
When three-dimensional warp-knitted fabric was used as the cup material that is used for underwear, as connecting line, the preferred use by fineness was that the fineness that the individual filament of 3～6dtex is formed is the multiply filament of 33～110dtex.
The reason that the fineness of individual filament preferably is set as 3～6dtex is as follows: if the fineness of individual filament less than 3dtex, so three-dimensional warp-knitted fabric has lower intensity and elastic force, thereby has than the shape stability of low degree and shaky.On the other hand, if the fineness of individual filament greater than 6dtex, connecting line is harder so.So connecting line can stretch out from the surface of three-dimensional warp-knitted fabric.The result is that the user may feel under the weather when the user dresses the fibre of being made by this three-dimensional warp-knitted fabric, and in addition, thereby fabric has relatively poor sense of touch firmly.
The reason that the fineness of multiply filament preferably is set as 33～110dtex is as follows: if the fineness of multiply filament less than 33dtex, then three-dimensional warp-knitted fabric has lower elastic force, thereby has the shape stability than low degree.On the other hand, if the fineness of multiply filament greater than 110dtex, thereby then fabric may firmly have relatively poor sense of touch.
By using the multiply filament as connecting line, even mold under high pressure, connecting line also is connected to each other ground, upper strata tissue and lower floor's ground tissue with different angles.Therefore, pressure can be disperseed.Therefore, connecting line can damage hardly, so three-dimensional warp-knitted fabric has outstanding resistance to compression.When the multiply filament was heated, the individual filament that equals multiply filament fineness with fineness was compared, and the degree of multiply filament sclerosis is lower.Therefore fabric can lose its elasticity hardly, and can guarantee thickness sufficient retention performance, shape stability and resistance to compression.
When using individual filament as connecting line, the high temperature and high pressure hardening of fabric during because of mold, and its elasticity can be destroyed.Therefore the shape stability of fabric and resistance to compression thereof may variation, and because connecting line stretches out from the surface of ground tissue, the user can feel under the weather.
The three-dimensional warp-knitted fabric that the present invention uses can form by the warp knitting machine that use has the Double-Russell braiding machine of two rows needle-bar respect to one another or has a V-type bed.In order to make three-dimensional warp-knitted fabric, preferably use the Double-Russell braiding machine with better space stability.Also preferred needle gage with the Double-Russell braiding machine is made as 9～28.
When three-dimensional warp-knitted fabric is used as the material that is used for underwear and sportswear, do not form opening portion in its surface by the surface of the smooth first ground tissue and the second ground tissue, can prevent that connecting line is by stretching out in the opening portion.Therefore, when the user dresses this underwear and sportswear, can make the user feel comfortable, and can prevent that user's skin from being seen through this underwear and sportswear.By using this three-dimensional warp-knitted fabric as upholstery material and analog, when the user was sitting on the chair, this three-dimensional warp-knitted fabric can make the user that comfortable sensation and sense of touch are preferably arranged.In addition, the ground tissue by being used in combination skin one side that is positioned at fibre and have concaveconvex structure or the three-dimensional warp-knitted fabric that is positioned at the structural tissue braiding in ground of eyed structure can be alleviated the sensation that swelters and adhere to better.
When using KES-F8 air permeability tester mensuration to be used for the gas permeability of three-dimensional warp-knitted fabric of the present invention, its gas permeability is preferably and is not more than 0.02KPas/m.
The air permeability of three-dimensional warp-knitted fabric preferably is set as the reason that is not more than 0.02KPas/m and is when using the KES-F8 air permeability tester to measure: if the air permeability of three-dimensional warp-knitted fabric greater than 0.02KPas/m, may have the sensation that swelters when brassiere of being made up of this three-dimensional warp-knitted fabric when user's wearing and analog so.
At three-dimensional warp-knitted fabric, fabric preferably is set as 80～120mm along the hardness of its warp-wise or broadwise.Reason is as follows: if the hardness of fabric greater than 120mm, then the sense of touch of fabric may be harder.On the other hand, if the hardness of fabric less than 80mm, then the DE of fabric is too high, thereby makes fabric may lack shape stability.When the hardness of fabric wherein is used as the material that is used for brassiere cup less than the three-dimensional warp-knitted fabric of 80mm, the shape that can not proofread and correct breast rightly.
In the present invention, the hardness of fabric is measured by the cantilever method of JIS L 1018.
In three-dimensional warp-knitted fabric, the thickness of fabric is preferably 2～12mm, more preferably 2.5～8mm.
If the thickness of fabric is less than 2mm, then fabric can lack shape stability and resistance to compression.On the other hand, if the thickness of fabric greater than 12mm, then fabric is heavier, and the sense of touch of fabric is not good.
The quality (quality of per unit area) of three-dimensional warp-knitted fabric preferably is set as 250～370g/m
2, 280～350g/m more preferably
2
The quality optimization of three-dimensional warp-knitted fabric is set as 250～370g/m
2Reason as described below.If its quality is less than 250g/m
2, then fabric lacks resistance to compression and shape stability.On the other hand, if its quality greater than 370g/m
2, then fabric may lack flexibility.
Second invention provides a kind of fibre of being made up of this three-dimensional warp-knitted fabric.
As mentioned above, the fibre of being made up of this three-dimensional warp-knitted fabric has outstanding shape stability, thickness retention performance, damping characteristics and gas permeability.Therefore, this fibre can be preferably used as the ornament that is used for brassiere cup and analog, sportswear, footwear and chair and the material of analog.Further preferably this fibre is used for the brassiere that clothes for example have cup.
For above-mentioned reasons, the first ground tissue that preferably should the three-dimensional warp-knitted fabric places a side of contact user skin.
This fibre preferably is used to have the clothes of the cup of being made up of this three-dimensional warp-knitted fabric.
Preferably should on cup, form projection by the three-dimensional warp-knitted fabric by hot pressing.
Even hot pressing should the three-dimensional warp-knitted fabric with the projection that forms cup after, cup also has outstanding damping characteristics, thickness retention performance and shape stability, and can keep original gas permeability preferably and sense of touch for a long time.Therefore, clothes with cup can keep suitable degree ground to proofread and correct the performance of udder shape for a long time, and the sensation that swelters and adhere to that the user is produced cause and, thereby make the user feel comfortable to uncomfortable stimulation of skin because of perspiration.
About should the three-dimensional warp-knitted fabric by the hot pressing mold with the condition of the projection that forms cup, the mold temperature preferably is set as 200～240 ℃, more preferably 230 ℃, and the mold time preferably be set as more preferably 45 seconds 30～60 seconds.
The thickness of the cup that should the three-dimensional warp-knitted fabric obtains by mold preferably is set as half that is about the thickness of three-dimensional warp-knitted fabric before mold.
About the air permeability of mold cup, preferably the air permeability that is recorded by the KES-F8 air permeability tester is for being not more than 0.025KPas/m.
When three-dimensional warp-knitted fabric was used as the material that is used for brassiere cup, the thickness of fabric preferably was set as 2～6mm, more preferably 2～4mm.
If the thickness of fabric is less than 2mm, then fabric lacks shape stability and resistance to compression, and can see skin through fabric.On the other hand, if the thickness of fabric greater than 6mm, then fabric is heavier and have a relatively poor sense of touch.
The thickness of fabric is measured by the method for using in an embodiment of the present invention.
This three-dimensional warp-knitted fabric not only can be used to the cup of clothes, and can be used for clothes the covering cup the zone and near the part of the armpit of cup.
Cup can not form by hot pressing, and forms by sewing up this three-dimensional warp-knitted fabric.
This three-dimensional warp-knitted fabric can be used to the cup of following clothes: coat for example has shirt, underwear vest for example next to the shin, brassiere sheet, Lingerie, leotard, swimming suit and the analog of brassiere.
As mentioned above, in first invention, the first ground tissue and the second ground tissue are connected the interconnected three-dimensional warp-knitted fabric of line along in the cross section of broadwise therein, and the first ground tissue has the ring that does not link to each other with connecting line with predetermined interval.Therefore, the first ground tissue has better gas permeability than the second ground tissue.As mentioned above, the first ground tissue has the ring that does not link to each other with connecting line with predetermined interval.On the other hand, because all rings of the second ground tissue are all linked to each other with the ring of the first ground tissue by a connecting line respectively, so thereby the gap that forms between the adjacent connecting line has gas permeability preferably greatly.Therefore, the first ground tissue has higher gas permeability, and simultaneously, the gap between the adjacent connecting line has better gas permeability.Therefore can improve the gas permeability of whole three-dimensional warp-knitted fabric, and the dry rapidly moisture that causes by perspiration.Therefore can alleviate the sensation that swelters and adhere to.
As mentioned above, because connecting line extends and do not change the number of connection of the connecting line that traditionally adopt from the first ground tissue to the second ground tissue with different angles,, the first ground tissue and second ground can depart from hardly so being organized on its broadwise.Therefore should have outstanding shape stability, thickness retention performance and damping characteristics by the three-dimensional warp-knitted fabric.
As mentioned above, because the ring that links to each other with connecting line that the first ground tissue has smaller amounts than the second ground tissue, so its sense of touch is organized softer than second ground.Therefore contact user's skin by the surface that makes the first ground tissue of forming the clothes cup, can make the user when dressing this brassiere, feel comfortable.
As mentioned above, the ring that does not link to each other with connecting line in the first ground tissue has higher gas permeability.Therefore, contact user's skin by making the surface with the ring that does not link to each other with connecting line in the first ground tissue of forming the clothes cup, drying is by the moisture of perspiration generation rapidly.Therefore can alleviate the sensation that swelters and adhere to.
The fibre of being made up of this three-dimensional warp-knitted fabric has outstanding damping characteristics, thickness retention performance and shape stability, and can keep original gas permeability preferably and sense of touch for a long time.This fibre can keep its shape, and the sensation of the sensation that the user is produced swelter, adhesion and to uncomfortable stimulation of user's skin.Therefore the user can feel comfortable when dressing or using it.
Even after this three-dimensional warp-knitted fabric was by the projection of hot pressing with the cup of formation clothes, cup also had outstanding damping characteristics, thickness retention performance and shape stability, and can keep original gas permeability preferably and sense of touch for a long time.Therefore, the clothes with cup can keep suitable degree ground to proofread and correct the performance of udder shape, and the sensation of the sensation that the user is produced swelter, adhesion and to uncomfortable stimulation of user's skin, therefore make the user feel comfortable.

The specific embodiment
Below in conjunction with accompanying drawing first embodiment of the present invention is described.
Fig. 1～4 are depicted as first embodiment of the present invention.Brassiere cup is formed by the three-dimensional warp-knitted fabric 10 shown in Fig. 1 and 2.
Weave three-dimensional warp-knitted fabric 10 in first embodiment by the Double-Russell braiding machine.As illustrated in fig. 1 and 2, three-dimensional warp-knitted fabric 10 is by organize promptly the first ground tissue 11 and the second ground tissue 12 and make the first ground tissue 11 and second ground organize 12 interconnected connecting lines 13 to be formed two-layerly.
The structure of Double-Russell braiding machine as shown in Figure 3.By using the Double-Russell braiding machine, weave the second ground tissue 12 with being incorporated into the wire gauze A1 and the A2 that knit among reed L-1 and the L-2 respectively, and weave the first ground tissue 11 with being incorporated into the wire gauze A5 and the A6 that knit among reed L-5 and the L-6 respectively.With being incorporated into the connecting line 13 of knitting reed L-3 and L-4 respectively the first ground tissue 11 and the second ground tissue 12 are connected to each other.
In particular, by using Double-Russell braiding machine " RD6DPLM-77E-22G " (available from Meyer company), the polyester fine filaments of 56dtex/24f by being used to knit reed L-1 and L-2 weaves the second ground tissue 12, and the polyester fine filaments that the polyester fine filaments of the 56dtex/24f by being used to knit reed L-5 and being used to is knitted the 84dtex/36f of reed L-6 weaves the first ground tissue 11.The connecting line 13 that is made of the polyester fine filaments of 110dtex/12f is used to knit reed L-3 and L-4.Thereby the first ground tissue 11 and the second ground tissue 12 be connected to each other make three-dimensional warp-knitted fabric 10.
As illustrated in fig. 1 and 2, along three-dimensional warp-knitted fabric 10 its broadwise (widths of knitted fabric, direction shown in the arrow A among Fig. 1) in the cross section (Fig. 2), in the first ground tissue 11, connecting line 13 connects every a ring, wherein encircles 11a-1 and links to each other with connecting line 13 and do not link to each other with connecting line 13 with its ring 11a-2 that replaces.On the other hand, in the second ground tissue 12, all ring 12a link to each other with connecting line 13, and wherein two connecting lines 13 link to each other with a ring 11a-1 in the first ground tissue 11 with different angles.
In first embodiment, the Connection Density of the connecting line 13 in the first ground tissue 11 is set as 50%, and the transverse width of connecting line 13 is set as 1～2 stitch.
In the three-dimensional warp-knitted fabric that makes, the thickness of fabric is set as 2～6mm.The air permeability of the fabric that is recorded by the KES-F8 air permeability tester is for being not more than 0.02KPas/m.The quality of fabric (quality of per unit area) is set as 250～370g/m.
As mentioned above, therein in the first ground tissue 11 and the second ground tissue 12 cross section by the broadwise (direction shown in the arrow A among Fig. 1) of the three-dimensional warp-knitted fabric 10 of connecting line 13 interconnected first embodiments, the first ground tissue 11 has the ring 11a-2 that do not link to each other with connecting line 13 and the ring 11a-1 that links to each other with connecting line 13 with interval respectively.Therefore the ring 11a-2 that does not link to each other with connecting line 13 has better gas permeability.On the other hand, because ring 12a all in the second ground tissue 12 link to each other with the ring 11a-1 of a connecting line 13 with the first ground tissue 11 respectively, so the number of connection between the connecting line 13 and the first ground tissue 11 is different with the number of connection between the connecting line 13 and the second ground tissue 12.Therefore each gap 14 that forms between adjacent connecting line 13 is all bigger, thereby has better gas permeability.
Because the gas permeability in the gap between the gas permeability of the ring 11a-2 that does not link to each other with connecting line 13 and the adjacent connecting line 13 is better, so can improve the gas permeability of whole three-dimensional warp-knitted fabric 10.
As mentioned above, because connecting line 13 extends to the second ground tissue 12 from the first ground tissue 11 with different angles, and do not change the number of connection of the connecting line 13 that tradition adopts, the first ground tissue 11 and the second ground tissue 12 can depart from its broadwise hardly.Therefore should have outstanding shape stability, thickness retention performance and damping characteristics by three-dimensional warp-knitted fabric 10.
As mentioned above, organize the surface of the first ground tissue still less to be positioned at a side of fibre and user's contact skin by the quantity that makes the ring that links to each other with connecting line than second ground, the user can feel comfortable when dressing this fibre.
As mentioned above, the ring 11a-2 that does not link to each other with connecting line 13 has higher gas permeability.Therefore be positioned at a side of fibre and user's contact skin by the surface that makes the first ground tissue 11, can alleviate the sensation that swelters and adhere to thereby the moisture that produces by perspiring is dried rapidly with the ring 11a-2 that does not link to each other with connecting line 13.
As shown in Figure 4, the cup 21 of brassiere 20 is made by this three-dimensional warp-knitted fabric 10.
In order to make cup 21, with three-dimensional warp-knitted fabric 10 cuttings and under 230 ℃ mold temperature 45 seconds the mold time of hot pressing to form projection.
The surface that has the first ground tissue 11 of the ring 11a-2 that does not link to each other with connecting line 13 with predetermined interval is positioned at a side of cup 21 and user's contact skin, and the surface of the second ground tissue 12 that all rings all link to each other with connecting line 13 respectively is positioned at the outer surface of cup 21.
The thickness of the fabric of the cup 21 that makes is set as 2～4mm.The air permeability of the cup 21 that is recorded by the KES-F8 air permeability tester is for being not more than 0.025KPas/m.
