Accompanying drawings and embodiments will be combined, and the invention will be further described:
By Fig. 1, we can clearly show that the principle of the present invention.Known woven fabric is by warp thread and weft yarn root in the industry
The continuous flexible porous material formed according to certain institutional framework.Fabric itself heat and moisture transmission characteristic exists during taking
Crucial effect is played in terms of human thermal comfort, needs to be balanced according to the different motion state of wearer (metabolic rate)
The effect of preserving heat and radiating heat of clothes.How to reach the dynamic in larger range corresponding to changeable environment and human motion state
Balance is one of the emphasis that each researcher is concerned about, in particular how reaches the water balance of skin skin surface.Fabric
Permeability is one of them key index, and related to the close structure of fabric, depending on the gap between yarn.It gets in gap
Greatly, gas permeability is better and warmth retention property is poorer.Based on above-mentioned consideration, Fig. 1 (a) basic unit illustrates fabric in non-dominant perspiration
Under the conditions of state, only moisture absorption is swollen rises for J2 tool in warp thread (J1, J2, J3), and J1 is foundation structure yarn, and J3 is foundation structure yarn
Or elastomeric yarn；Weft yarn (W1, W2, W3) fabric W1, W3 after moving perspiration are foundation structure yarns, and the geometric dimension of yarn is protected
It holds and is basically unchanged, W2 is linear deformation yarn, significantly attenuates and extends after moisture absorption.Therefore the architectural characteristic of fabric will will form two
Kind result of variations:
1. the gap between yarn significantly increases, this will lead to increasing for gas permeability；
2. exist simultaneously foundation structure yarn and longitudinally, laterally textured yarn in fabric, thus fabric will in thickness direction and
Part occurs after length-width direction moisture absorption simultaneously to deform, this will cause original smooth fabric surface formation and rises and falls and out-of-flatness.Into
And the area of fabric and skin contact can be efficiently reduced when wearing and perspiring.
Can increase the gap in fabric construction after moisture absorption is thicker or elongated in relation to fabric yarn, we can use substantially
Geometrical principle verified.Fig. 2 and Fig. 3 show respectively yarn possible structure in shuttle-woven fabric.
The basic theory of the present invention is shown in Fig. 2, i.e., two circle internal common tangent length computation models.Envelope in relation to circle
Line and length of base tangent calculating have had deep discussion just not do deep explanation and discussion herein in geometry, only
It is simply to list corresponding calculated result.To two circles, (with C1 for the first round heart, R1 is radius；It is second round with C2
The heart, R2 are radius；The internal common tangent P1P2 length of two circle center distance d) can be converted to the calculating to triangle C1C2C.Therefore
Available following formula
Cos a=(R1+R2)/d
∠ a+ ∠ b=90
Similarly for the calculating of two circle outside common tangent P1P2 also available following formula
Sin a=(R2-R1)/d
∠ a+ ∠ b=90
It is hereby achieved that granddad cuts in either two circles, the length of common tangent can be all calculated, in conjunction with
The variation of fabric in a thickness direction and Fig. 1's (b) shows that we exist at available designed fabric in the present inventive method
The increase (increase of open space) of fabric breathability can be reached under conditions of absorption moisture.
Specific embodiment
Example one
A kind of fabric yarn is proposed in the invention patent utilizes different materials (yarn) moisture absorption to react after absorbing water
Difference enables fabric Unclosing structure after moisture absorption to increase vapor permeation area, reduces the flatness of fabric surface, improve after perspiring
The comfort of dress.
It is the schematic diagram of this example shown in Fig. 4.This is a kind of typical plain weave structure.In this element:
● warp thread C1 is foundation structure yarn, selected material be common terylene (100% Polyester Yarns, 40S, strand: 1,
Zhuji City people's livelihood Textile Co., Ltd., Zhejiang Province) its regain is 1.5%；
● C2 is moisture absorption transversely deforming yarn, and selected material is viscose rayon (ingredient and content: 100% viscose glue, yarn
Branch: 40s, strand: the Guangdong 1, Dongguan City great Lang hero country textile trade row).Its regain is 12% or so.It is situated between according to Baidupedia
It continues
(http://baike.baidu.com/item/%E7%B2%98%E8%83%B6%E7%BA%A 4%
E7%BB%B4) viscose rayon has good hygroscopicity, and under the conditions of general atmosphere, regain is 13% or so.After moisture absorption
Significant expansion, diameter increase up to 50%.
● C3 is identical as C1
● weft yarn with VENTCOOL and ordinary polyester 1:1 order enter latitude (VENTCOOL,
MITSUBISHI RAYON Japan, http://mrtx.co.jp/en/sozai/ventcool.html)；Commonly
Polyester Yarns parameter is consistent with C1 yarn.
Fig. 4 is that the present invention shows a basic woven computing unit model
Available by Fig. 4, after fabric moisture, the diameter of C2 yarn becomes R2 by R3, and foundation structure yarn at this time
C1 does not change with the diameter of C3.At the same time, become in weft yarn linear deformation yarn due to using moisture absorption elongation yarn, diameter
Carefully, while length.Theory introductory section according to the present invention, the gap between fabric yarn are increased, and gas permeability obtains
To raising；The presence of foundation structure yarn simultaneously, due to its relatively low regain, then almost without change in terms of geometric dimension
Change.Therefore the out-of-flatness of fabric surface is also resulted in.Simultaneously because the presence of foundation structure yarn, after the elongation of linear deformation yarn,
The external force being applied on fabric is nearly all undertaken by foundation structure yarn, therefore problem also low to viscose glue kind fabric wet strength
It improves to some extent.
Example two
On the basis of example one, twill structure that can also be following in construction.Warp thread increases by one in this structure
C4, material are identical as C1 characteristic.The design of weft yarn is identical as example one as the arrangement for entering latitude order.Main change is exactly
Such as the plain weave construction of example one, yarn is one on the other, to be changed to oblique spinning structure once on two.It can be with by Fig. 5
After obtaining fabric moisture, transversely deforming yarn it is thicker, driven the rising of linear deformation yarn, transversely deforming yarn position is knitted
The thickness of object also accordingly thickens, and drives the gap of linear deformation yarn and adjacent yarn arrays, while linear deformation yarn was extending
Attenuating in journey further enhances the trend of this gap increase.Therefore, Fig. 5 clearly reveals fabric of the invention and sets
Meter method can realize in various fabrics structure, meanwhile, insider can realize a variety of under the guidance of the principle of the invention
The combination of different structure and material.
Fig. 5 twill shuttle-woven fabric calculated examples
The weft-knitted single-side fabric of example three
(a) schematic diagram changed after the basic unit moisture absorption of the basic unit (b) of plain cloth example of the present invention
The basic unit and deformation signal of Fig. 6 example of the present invention
Fig. 6 is with weft-knitted one of structure and yarn combination, is equally to utilize the principle of the invention.In the process taken
Itself heat and moisture transmission characteristic of middle fabric plays crucial effect in terms of human thermal comfort, needs different according to wearer
Motion state (metabolic rate) balances the effect of preserving heat and radiating heat of clothes.
Fig. 6 (a) basic unit illustrates fabric state under the conditions of non-dominant perspiration, L1 black (the identical expression of warp knit)
For transversely deforming yarn, L2 grey (the identical expression of warp knit) be linear deformation yarn, L3 white (the identical expression of warp knit) is basic structure
Yarn.(b) fabric linear deformation yarn after moving perspiration, significantly attenuates and extends after moisture absorption, such as H ' > H.L3 foundation structure yarn base
The original shape of this holding, to guarantee that fabric still has compared with stiff stability after movement is perspired.Therefore the architectural characteristic of fabric
Three kinds of result of variations will be will form:
1. from Fig. 6 fabric top view, linear deformation yarn attenuates elongation after moisture absorption.Because of foundation structure yarn geometric dimension
Stability, the size for enclosing arc can remain unchanged, and loop pillar is elongated is also equivalent to H ' > H.The area of so coil also can
Become larger, the heat dissipation stomatal size provided also accordingly increases.
2. the same with the principle of tatting, cross-sectional direction has the diameter of section of transversely deforming yarn to become larger after movement is perspired.
Due to transversely deforming yarn moisture absorption diameter become larger cause fabric cross section product become larger perspire after fabric provide air hole become larger.
3. exist simultaneously foundation structure yarn and longitudinally, laterally textured yarn in fabric, thus fabric will in thickness direction and
Part occurs after length-width direction moisture absorption simultaneously to deform, this will cause original smooth fabric surface formation and rises and falls and out-of-flatness.Into
And the area of fabric and skin contact can be efficiently reduced when wearing and perspiring.
Can increase the gap in fabric construction after moisture absorption is thicker or elongated in relation to fabric yarn, we can use substantially
Geometrical principle verified, Computing Principle and method refer to Fig. 3
In the above inventive principle reversible cloth and its fancy fabric are also included in
Four knitted fabric of example

Fig. 7, Fig. 8 are with warp knit one of which structure and yarn combination, are equally to utilize the principle of the invention.What is taken
Fabric itself heat and moisture transmission characteristic plays crucial effect in terms of human thermal comfort in the process, needs according to wearer not
The effect of preserving heat and radiating heat of same motion state (metabolic rate) balance clothes.
Fig. 7 (a) basic unit illustrates fabric state under the conditions of non-dominant perspiration, and black is transversely deforming yarn, grey
It is basic structure yarn for linear deformation yarn, white.(b) when move perspire after fabric linear deformation yarn, significantly attenuate after moisture absorption with
Elongation, such as H ' > H.Foundation structure yarn keeps original shape substantially, so that it is relatively strong to guarantee that fabric still has after movement is perspired
Stability, longitudinal loop density do not change substantially.Therefore the architectural characteristic of fabric will will form three kinds of result of variations:
1. from Fig. 7 fabric top view, linear deformation yarn attenuates elongation after moisture absorption.Because of foundation structure yarn geometric dimension
Stability, the size of coil, which can remain unchanged, is also equivalent to D=D ', and underlap be the moisture absorption of linear deformation yarn it is elongated
Also it is equivalent to H ' > H.So the area of coil can also become larger, and the heat dissipation stomatal size provided also accordingly increases.
2. the same with the principle of tatting, cross-sectional direction has lateral change after movement is perspired from Fig. 8 fabric side view
The diameter of section of shape yarn becomes larger.The transversal height of fabric is caused to become larger since transversely deforming yarn moisture absorption diameter becomes larger, and linear deformation
Yarn keeps underlap elongated, the distance between two wales H ' > H.Calculating cross-sectional area according to geometrical principle can become larger, from
And the air hole that fabric provides after perspiring is become larger.
3. exist simultaneously foundation structure yarn and longitudinally, laterally textured yarn in fabric, thus fabric will in thickness direction and
Part occurs after length-width direction moisture absorption simultaneously to deform, this will cause original smooth fabric surface formation and rises and falls and out-of-flatness.Into
And the area of fabric and skin contact can be efficiently reduced when wearing and perspiring.
Can increase the gap in fabric construction after moisture absorption is thicker or elongated in relation to fabric yarn, we can use substantially
Geometrical principle verified, Computing Principle and method refer to Fig. 3.
In the above inventive principle warp knit reversible cloth is also included in.
