Description

A kind of have infrared management characteristic fabric and preparation method thereof
Technical field
The present invention relates to a kind of Design & preparation method of functional textile.The method, by fabric specifically being arranged or selects to have the yarn of specific function or yarn being carried out to specific finishing functions, designs different fabric structures simultaneously and has different infrared signatures to reach the fabric two sides of making.
Technical background
No matter directly or indirectly, the sun provides the needed energy for tellurian all life.The high sun being suspended in sky, its surface temperature, up to 6000 ℃, is launched the electromagnetic wave of a plurality of frequency ranges incessantly, comprising ultraviolet, visible ray and infrared ray.Correspond to the gross energy that the sun arrives the earth, ultraviolet band accounts for 6.8% gross energy (0.5%UVB, 6.3%UVA); 38.9% Energy distribution is at visible light wave range; About 54.3% Energy distribution is at infrared band.
Clothes in wearing process ceaselessly the skin of human body contact, affect the wet exchange of heat between human body and environment.In the past few decades, consumer sees by dressing well the requirement of clothes, and being transformed into not only will dress well sees also will wear comfortable.Therefore for physiological effect just being become to considerably important after all clothes dressings.The research first having has shown that the multi-direction transmission characteristic (the aqueous water management characteristic of fabric) of aqueous water in clothes has significant impact to the comfortableness of dressing.The most basic function of clothes is exactly the changes in temperature that regulate us, resists extraneous variations in temperature.
Because behaving, be a homeothermal animal, our body temperature need to maintain in a very narrow region, if surpass this scope, will feel uncomfortable, even dead.The research first having shows, when our skin surface mean temperature is at 33 ℃ to 35 ℃ and while there is no sweat on its surface, we can feel comfortably cool conventionally.Human body and environment carry out heat exchange and conventionally in following three kinds of modes, carry out: convection current, conduction and radiation.Conduction mode is to realize by the interaction in short distance between molecule or electronics; Also there is certain conduction with mixing in the mechanical flow that convection current combines fluid simultaneously; When heat energy transmits in the mode of radiation, be to realize at infrared spectrum with electromagnetic form.First there is research to point out the infrared transmission characteristic of fabric and the overall comfort of dressing to have certain relation, and affect the mean temperature of skin.
Therefore being just necessary to develop a kind ofly novel can have to skin surface temperature the functional fabric of certain regulating power.For example, under summer burning sun hot weather, main thermal source comes from the sun that includes outside line frequency range, wants to make people to have nice and cool sensation, and garment material need to can be reflected back the infrared radiation of arrival in environment as much as possible.The sweat of human body surface is delivered to as much as possible to the outer surface of fabric simultaneously, and carries out that volatile zone is walked heat so that wearer's skin keeps nice and cool at outer surface.On the other hand, outdoor main thermal source is human body self in the winter time.Clothes need to be reflected back the infra-red radiation that comes from human body human body to retain heat.For certain some specific purposes, routine military use need to will all be covered the infrared-ray shielding as far as possible of object.
Energy can be with electromagnetic wave, convection current, and these three kinds of modes of radiation are carried out.The radiation mode transmitting with electromagnetic mode is that one group of atom is transmitted in space in the mode of fluctuation, so heat energy just can be propagated and not need medium at vacuum state as solar energy.Infrared ray is to propagate with linear fashion, and its wavelength ratio is wide as seen.
What infrared ray represented is the electromagnetic wave within the scope of certain frequency, starts from the upper limit of visible red, terminates in the emblem ripple that is generally used for communication, wave-length coverage at 1 millimeter to 750 nanometers.Whole infrared band can further be divided into near-infrared again, in infrared, three wave bands of far infrared.
0.076-1.5microns=near-infrared (NIR);
1.5-5.6microns=in infrared (MIR); With
5.6-1000microns=far infrared (FIR).
All objects more than absolute zero all can be continuously outside emitting electromagnetic wave, its wavelength is relevant with the temperature of body surface.The radiation of object is all to exist with ultrared form at ambient temperature, and seldom the form with visible ray occurs.The infra-red radiation dominant wavelength ranges of human body self is at 9 to 10 microns under normal circumstances.
Work as infrared radiation source, for example sunshine includes whole frequency spectrum, and when it arrives fabric face, energy not only comprises the energy IR (I of infrared band ir) also comprise the energy (I of other wave band other) (Fig. 1).On the other hand, after cloth specimen absorbs energy, its temperature by continuing, rise and again its two surface emitting go out extra infrared energy.Therefore the infrared light intensity of transmission can be expressed as:
I t=I dt+I et (1)
Infrared light intensity on reflecting surface can be expressed as simultaneously:
I r=I dr+I er (2)
In formula: I dtand I drthe direct reflection and transmission intensity (W/m of material performance 2).What Iet and Ier represented specimen surface launches light intensity (W/m again 2).
Retrieval according to us to United States Patent (USP) storehouse, relevant heat retention of the fabric can conduct extensive research.Some patented technology, for example, 5,150,476,6,662,389 improve warmth retention property by increasing still air layer to realize. patent 6,662, and 389 have applied for a kind of side that realizes variable thermal property; Patent 6,312,784 more point out to utilize shape-memory material to regulate the warming characteristic of fabric.Patent 6,583,074,5,534,335 instructed a kind of by fabric with metal fibre or change the warming characteristic of fabric by the method for coating; Patent application 20030057750, introduced one make automotive seat nice and cool realize technique; Patent 5,787,525 instructed a kind of with multiply cloth structure and add therein the method for tourmaline to change the infrared signature of fabric.Patent 5,787,525 have instructed at a kind of ceramic powder that adds in shoe-pad to strengthen the product processes of its infrared signature.

Summary of the invention
Core of the present invention is to have proposed a kind of new function fabric method for designing, thereby it is the design of fabric face structure at all and utilizes functional material to modify and knit the thermal property that surperficial infrared signature is realized adjusting fabric.This concept of the infrared management characteristic of fabric has been proposed.This concept definition is as follows:
Infra-red radiation management fabric
Fabric two surfaces have specially designed infrared signature, because thereby these specially designed infrared signatures make infrared external reflection and the different transmission characteristic that makes fabric have the ability to make heat energy of transmission capacity on fabric two sides, the particularly radiation capacity of heat transmission is controlled, thereby has influence on the overall heat transfer characteristic of fabric.Such fabric is referred to as infrared management fabric.
This kind fabric is by the characteristic being achieved as follows:
(1) the two different infrared signature in surface
(2) super nice and cool, or
(3) super warm, or
(4) high insulation
For realizing above-mentioned target, in the present invention, infrared management characteristic surface material is mainly divided into two large classes: cool fabric (SCF) and Calefaction type fabric (SWF).
Affect the wear the clothes infrared radiation source of thermal comfort of people and mainly contain two kinds, a kind of is to come from the external high temperature sources such as the sun; Not a kind of is to come from self (Fig. 2).Solar radiation I 0be included in the energy I of infrared band irwith its wave band energy I others. under identical air penetrability condition, when radiation luminous energy (comprising visible ray and non-visible light) arrives fabric face, a part will be reflected back toward (I in atmosphere fre), part energy will be absorbed by fabric and again emit, and strive and will directly penetrate fabric (I for one simultaneously fte). simultaneously when fabric is through with it, the infrared ray (I that human body self emits se) partly will be reflected back health (I by fabric ser), (I partly set) will be through in fabric entered environment.
In order to make there is nice and cool sensation in the process of dress, fabric is near the side of skin, and being defined as inner surface should have lower transmissivity, and has higher reflectivity at its another side (being defined by outer surface).In this case, the infrared energy that mainly comes from the sun will be reflected back toward environment and makes the temperature rise of fabric inner surface relatively low.
On the other hand, in wearing process, keep warm sensation, its infrared characteristic of fabric is with above-mentioned contrary.Main infrared radiation source is from human body.Therefore the inner surface of fabric need to have higher reflectivity, human-body emitting infrared energy is out reflected back, and have outer surface also to have lower reflection characteristic so that fabric absorbs more infrared energy (Fig. 3).
Therefore by following method, realize the infrared signature of two, fabric modified in the present invention:
1, cool fabric has bright and clean outer surface and soft coarse inner surface;
2, warm-keeping type shell fabric has soft coarse outer surface and bright and clean inner surface;
3, utilize specific technique and auxiliary agent to carry out infrared finishing functions to fabric, yarn or fiber;
4, by given institutional framework, carry out fabric preparation.

The specific embodiment
The object of this invention is to provide a kind of feasible technique and ordering plan and there are two different infrared signatures to realize fabric, to reach different infrared management functions.This comprises the following steps or flow process:
1, by yarn, set out: the infrared enhancing processing → fabric texture of part yarn, fiber and bake → fabric of weaving → fabric wash water → final products;
2, by fabric, set out: fabric two is flushing bake → fabric of the differential arrangement → fabric of external radiation wash water → final products.
Preliminary finish to yarn or fiber, its objective is its infra-red radiation ability of improving, thereby the organizational structure design that coordinates fabric with the yarn that does not have to process and fiber reaches two masks of fabric, has maximized infrared signature difference.
The Main Ingredients and Appearance of knitting infrared signature enhancing formula for fiber, yarn comprises:
(1) infrared reinforcing material 1-300g/L
(2) fiber surface can be modified auxiliary agent 0-100g/L

(4) crosslinking agent 0-50g/L
(5) thickener 0-50g/L
(6) dispersant 0-50g/L
(7) other (water)
In this formula, material used can be any known substance meeting the demands, concrete example is as follows: for infrared enhancing functional material, can be any known but be not limited to known infrared enhancing nano material, can be for example Nano Silver, Zr02, Zn0 and A1203 etc.Conventionally this type of metal inorganic nano material can also provide extra function as anti-ultraviolet or antibacterial.
Dispersant can be fat alcohol ethoxyl compound or fatty acid ethoxy compound or Ethanol Ethoxylation compound etc.Crosslinking agent can be the organic chemistry goods with two or more free hydroxyl groups, such as polyethylene glycol etc.; Adhesive, thickener can be any known chemical productss.It can be hydrophilic finishing auxiliaries that fiber surface can be modified auxiliary agent, also can be hydrophobic type finishing auxiliaries, they can be, but be for example not limited to water imbibition quaternaries cation softener, organosilicon hydrophilic finishing agent, anionic hydrophilic silicone fabric finishing agent, fluorinated polymer, paraffin-slaine water repellent, contains the metal coordination valence solvay-type water repellent of LCFA etc.
Traditional fiber yarn finishing technique is all applicable to this processing.
It is mainly to form different infrared signatures owing to causing unique heat energy transmission characteristic for two surfaces at fabric that fabric of the present invention carries out its object of organizational structure design.Further develop this concept, rear finishing technique also can be applied in the present invention to realize single-sided fabric finishing, thereby realizes the inconsistent of two infrared signatures.The method conventional to single-sided fabric finishing can be, but be not limited to serigraphy, spraying, coating etc.
The fabric that further, multilayer can be had to a Different Red external characteristics is fit together and is formed different infrared management characteristics by compound method.For example smooth fine and closely woven light woven fabric and dark fluffy knit fabric can be carried out compound, thereby form different infra-red radiation heat transfer characteristics.
Further develop this concept, more single-sided fabric finishing technology also may be served new differential function for webbing again.For example such arrangement can be in the inventor's US Patent No. 6806,214, US6, and 454,814B1 and US6,499,338B2 finds detailed explanation and application, and has realized the difference transmission of aqueous water between fabric two surfaces.
