Summary of the invention
The invention provides a kind of cool-down garments of avoiding heat, it comprises outer fabric, internal layer fabric and makes nonwoven flocculus between outer fabric and internal layer fabric, it is characterized in that described nonwoven flocculus made by the fiber of high water absorbing capacity.
In a specific embodiments of the present invention, described internal layer fabric is the hydrophobic one-way moisture-guiding fabric of inner surface.This internal layer fabric can be the form of common employed any fabric in this area, as woven fabric, knitted fabric or nonwoven form.When the internal layer fabric of described one-way wet-guide touches the sweat on human body skin surface, sweat can be conducted to outer surface and entered the nonwoven flocculus by the hydrophobic inner surface orientation, form differential capillary effect, and can avoid the moisture adverse current, thereby make the inner surface of skin to keep dry and comfortable.
In a specific embodiments of the present invention, described outer fabric is hydrophobic one-way moisture-guiding fabric of outer surface or proofed breathable fabric.
Nonwoven flocculus between internal layer of the present invention and the outer fabric is made by the fiber with high water absorbing capacity.In a specific embodiments of the present invention, the fiber of described high water absorbing capacity is a calcium alginate fibre.Calcium alginate fibre known in the art has the high-hydroscopicity energy, can absorb own wt 20-30 aqueous water doubly.Yet although the nonwoven of being made by pure calcium alginate fibre has high water absorbing capacity, it once can harden into block after the suction, and feel is firm.Therefore, in other specific embodiments of the present invention, the fiber of described high water absorbing capacity is the composite fibre of calcium alginate fibre and nylon fibre or is the composite fibre of calcium alginate fibre and polyster fibre, perhaps is the composite fibre of calcium alginate fibre, nylon fibre and polyster fibre.In the composite fibre of calcium alginate fibre and nylon fibre, the content of nylon fibre is counted 10-30 weight % with the gross weight of composite fibre; In the composite fibre of calcium alginate fibre and polyster fibre, the content of polyster fibre is counted 10-30 weight % with the gross weight of composite fibre; In the composite fibre of calcium alginate fibre, nylon fibre and polyster fibre, in the gross weight of composite fibre, the content of calcium alginate fibre is 40-80 weight %, and the content of nylon fibre is 10-30 weight %, and the content of polyster fibre is 10-30 weight %.
Preferably, the nylon fibre in the nonwoven flocculus of the present invention is through silver-plated processing, thereby is provided at the antibacterial deodourizing effect after the human sweat infiltrates.
Preferably, the polyster fibre in the nonwoven flocculus of the present invention is the groove polyster fibre, thereby has improved the capillary effect of fiber, and the aqueous water that helps nonwoven inside is guide surface and being dispersed in the air swimmingly, to promote scattering and disappearing of heat.Those skilled in the art can regulate the ratio of nylon fibre and polyster fibre as required, thereby obtain suitable antibacterial deodourizing and water guide effect.
Nonwoven flocculus of the present invention can effectively suck aqueous water owing to its high water absorbing capacity, because the inner surface of internal layer fabric and the outer surface of outer fabric are hydrophobic, therefore the aqueous water that sucked of nonwoven flocculus can adverse current to skin, can not be extruded yet, can remain in effectively in this nonwoven flocculus.And when skin was perspired, the one-way wet-guide effect of internal layer fabric also can make sweat spread and to absorb to the nonwoven flocculus.Aqueous water in the described nonwoven flocculus (comprise absorption add water and sweat) can further diffuse to the outer fabric surface evaporation, thereby reduces the surface temperature with the clothing of Body contact, brings the wearer dry cooling feeling.Because nonwoven flocculus lining of the present invention has high water absorbing capacity, its aqueous water that sufficient quantity can be provided is to carry out evaporative heat loss, thereby can reduce wearer's skin surface temperature within a certain period of time, be specially adapted to the staff of continuous firing under hot conditions.
The cool-down garments of avoiding heat of the present invention is easy to use, and cost of use is cheap, need not other refrigeration plants, only needs simple water-filling can carry out recycling of water-filling-evaporation.Its water-filling method is with in the cool-down garments steep water of avoiding heat of the present invention, but by craft or mechanical presses water is entered in the nonwoven flocculus through the internal layer and the outer fabric of the one-way wet-guide on about surface, and the outward appearance of this cool-down garments of avoiding heat does not change before and after the water-filling.Behind a water-filling, the cool-down garments of avoiding heat of the present invention can continue cooling about 120 minutes under 40 ℃ the environment temperature.And the cool-down garments of avoiding heat of the present invention is very light, and outward appearance is succinct, is applicable to as the staff who waits particular job post on duty that stands guard.
