When using water adsorption balancing a survey under 80% relative humidity, substrate fabric 102 can absorb the about 0- of their weight in moisture
2.0%, for example, about 0.25-1.5%, about 0.5-1.0%, or about 0.8%.On the contrary, in each embodiment, when at 30 DEG C
When with using water adsorption balancing a survey under 80% relative humidity, superabsorbent polymer element 104 can absorb them in moisture
Weight about 3.0-20%, for example, about 3.3%, about 5.0%, or about 10%.In some embodiments, high-absorbable is poly-
Close construction element 104 more moisture can be absorbed, such as the weight in water about 50% or even 100%.
In each embodiment, superabsorbent polymer element 104 can have high several times of suction than substrate fabric 102
The property received, such as absorbability is about 2 times of substrate fabric 102,3 times, 4 times, 5 times, 10 times, 20 times, 50 times, 100 times, 200 times, or

The moisture of about 3.3 weight % can be absorbed when measuring under above-mentioned condition, and only about 0.8 weight % can be absorbed in substrate fabric 102
Moisture so that there is about four times of difference in absorptivity between substrate fabric 102 and superabsorbent polymer element 104.
It is without being bound by theory, it is believed that absorptivity difference between substrate fabric 102 and superabsorbent polymer element 104 by moisture from
Substrate fabric 102 sucks in superabsorbent polymer element 104, to enhance evaporation cooling and generate in substrate fabric 102
Dry sensation.
In each embodiment, superabsorbent polymer element 104 can be with substantially discontinuous array or pattern side
Formula setting, some substrate fabrics 102 can be exposed in adjacent superabsorbent polymer element 104 whereby or adjacent high-selenium corn

The discontinuous pattern of part 104 can take the form of grid, grid or other interconnection patterns.
As shown in Figure 1A and 1B, superabsorbent polymer element 104 be located at substrate fabric 102 towards wearer skin
On surface, and as moisture 106 contacts substrate fabric 102 (Figure 1A) (for example, in the form of sweat of the skin of wearer), by
Divide diffusivity in the high moisture wicking rate of substrate fabric and low water resistant, begins through 102 horizontal proliferation of substrate fabric
With dispersion (Figure 1B).In some embodiments, substrate fabric 102 can be handled with hydrophilic compounds to increase its moisture core
It inhales rate or is handled with hydrophobic compound to help moisture mobile with desired orientation.The low absorptivity of substrate fabric is (with height
The absorptivity of absorbable polymer element 104 is compared) also moisture is allowed freely to advance in coolant 100.
As shown in Figure 1 C, then moisture can contact superabsorbent polymer element 104 and can start to be absorbed, from
And enhances the evaporation cooling by substrate fabric 102 and generate dry sensation for user.For example, in some embodiments, it is high
Absorbable polymer element 104 absorbs moisture from the substrate fabric 102 of surrounding, causes evaporation to accelerate and allows substrate fabric
102 rapid draings, for example, than no superabsorbent polymer element 104 substrate fabric 102 dryly faster.In the process
In, superabsorbent polymer element 104 absorbs moisture from substrate fabric 102, and this redistribution of moisture passes through following two
A factor and be promoted: the absorbent properties of superabsorbent polymer element 104 and the low water resistant point diffusivity of substrate fabric
With absorptivity lower compared with superabsorbent polymer element 104.Moisture is first from substrate fabric 102 to superabsorbent polymer
It is cooling that the redistribution of part 104 accelerates the evaporation from substrate fabric 102 (thus skin from user), and also prepares
The coolant 100 cooling for the longer time.
In each embodiment, moisture can have than it in superabsorbent polymer element 104 in substrate fabric
Higher equilibrium concentration in 102.Without being bound by theory thinking when superabsorbent polymer element 104 is from substrate fabric 102
When absorbing moisture, this species diversity of absorbency level can generate concentration gradient in coolant 100.In each embodiment
In, moisture is displaced substrate fabric 102 and enters superabsorbent polymer element 104 by moisture concentration gradient.When high-absorbable is poly-
When conjunction construction element 104 absorbs moisture from substrate fabric 102, substrate fabric 102 can absorb more moisture, such as come itself
The sweat of body.
As shown in figure iD, according to each embodiment, the moisture being retained in superabsorbent polymer element 104 causes to prolong
Long evaporation displaces moisture along the direction (referring to arrow) far from wearer skin, until coolant 100 returns to dry shape
State.During the cooling stage, substrate fabric 102 can be largely drying, and the major part of coolant 100 is cooling
Function can be provided by the evaporation from superabsorbent polymer element 104 during extended cooling stage.Each
In embodiment, superabsorbent polymer element 104, which is arranged against on the skin of wearer (or side), can help to wear
Wearer experiences extended transpiration-cooled feeling.For example, the evaporation from superabsorbent polymer element 104 leads to cooling member
The temperature of part 104 reduces, and mode is roughly the same with the cooling mode of skin is evaporated from skin surface.Therefore, in each implementation
In mode, colder superabsorbent polymer element 104, which is arranged on the surface towards body of substrate fabric 102, to be allowed to wear
This cooling feeling of wearer's perception, and if superabsorbent polymer element 104 is located at the surface of substrate fabric 102 faced out
On, this cooling feeling may be less obvious.In some embodiments, cooling fabric disclosed herein can provide cooling rank
Section is defined as caused by liquid/sweat evaporation of specific quantity the cooling period, as long as the cooling stage is only by substrate fabric list
It solely provides, can continue for 110%, 120%, 150%, 200% (or even longer time).
Before the present invention discloses, it is widely believed that and cooling element is arranged on the surface of substrate fabric 102 faced out
Excellent cooling effect will be generated, because this set allows the evaporation from superabsorbent polymer element 104 not by substrate
Fabric 102 hinders ground to carry out.However, as disclosed herein, it has now been found that set superabsorbent polymer element 104
It sets and enhances the cooling feeling of wearer's perception on the surface towards body of substrate fabric 102, while also moisture being allowed to steam
Hair and the steady rate for passing through substrate fabric 102.
As described in more detail below, superabsorbent polymer element 104 may include one or more hygroscopic polymers,
Such as polymer that is absorbable and retaining liquid, and in some instances, it can be relative to the extremely large amount of liquid of its mass absorption.
The hygroscopic polymer for absorbing big quantity of fluid is referred to as super absorbent polymer.The water suction of hydrogel is classified as when this crosslinking
Polymer is bonded by the hydrogen with hydrone absorbs aqueous solution.The ability that super absorbent polymer absorbs water is usually aqueous solution
The factor of ion concentration.For example, 500 times of its weight can be absorbed in super absorbent polymer in deionized water and distilled water
(for example, 30-60 times of its own volume), and up to 99.9% liquid can be become, but it is water-soluble when being put into 0.9% salt
When in liquid, absorbability is down to about 50 times of its weight.
In each embodiment, total absorptivity and Swelling Capacity can be by being used to prepare the type of the crosslinking agent of gel
It is controlled with degree.The super absorbent polymer of low-density crosslinking usually has higher absorption capacity and is expanded into larger journey
Degree.The super absorbent polymer of these types also has more soft more tacky gel form.High crosslink density polymer is shown
Lower absorbability and swelling, but gel strength is firmer, and is able to maintain granulated under moderate pressure
Shape.
