<application of composite material>
The composite material of the utility model can satisfy the needs that particular surroundings uses, and be suitble to prepare down-proof fabric, swimming
Fill fabric or outdoor sport fabric.
Down-proof fabric
Natural feather is a kind of heat insulating material that natural lightweight is excellent, and insulation garment and bedding field have extensively in winter
Application, but it is very light and easily flows and moves with air, and is very easy to gap from fabric yarn or tissue
Or it is slowly drilled out in the pinprick micropore of sewing.The natural feather worn out, which is liable to stick on other clothings, influences beauty, also may be used
Can cause sensitive group respiratory tract not just as asthma the problems such as.In addition, be also easy to breed the microorganisms such as acarid inside natural feather, it
The smell that generates and certain sensitive materials, human allergy's problem is easily caused, especially to sensitive groups such as old man and children
For.
As natural feather covering material it may first have to solve the problems, such as to bore suede very well.Traditional down-proof fabric has a two major classes: one
Class is terylene or nylon high-count and high-density woven fabric, very small to cannot bore suede by warp and weft gap.In addition one kind is fabric back
Either compound one layer of non-porous or micropore the film in two shell fabrics centre carrys out anti-chiseling down to seal suede with the channel that air leaks.
Traditional anti-chiseling down theory is that hole on fabric is accomplished to very little as far as possible, and the small micro-pore diameter that arrives is than suede branch diameter (8-
30 μm) it is also small or at all substantially non-porous.For example, highly dense fully drawn yarn (FDY) DOWNPROOF FABRIC of conventional monolayers be exactly pass through it is very high
Weft density the hole on fabric is enclosed in 2-5 μm and its hereinafter, still this smooth FDY yarn is in sewing thread by masterpiece
Under, longitude and latitude intertwined point easy glide is by Kong Bian great herein, and when air is gone out from hole high speed in suede packet, natural feather also flies out therewith
Bore suede.Either two layers of non-porous overlay film down-proof fabric or three layers of joint product, if there is what is generated under external force
Micropore (micropore that such as sewing needle thorn generates), when no external force squeezes air in suede packet, the convergent force of elastic membrane can closed porosity
Do not run suede.But when relatively large external force is when airtight suede packet (when such as strenuous exercise or external pressure act on suddenly), wink
Between the power that is collected on micropore be it is very big, the micropore of original very little may also be swollen by moment in elastic membrane, including original film
At upper sewing thread by the closed micropore of elastic force can also with moment by spreading, suede piece with air quickly from being run out of by the micropore of spreading and
Bore suede.In short, high-density fabric and elastic overlay film fabric, the inner wall smooth of suede envelope material and the coefficient of friction of suede to conventional structure
Small, suede moves about in suede packet with air everywhere, weak link of the moment in the easy expansion micropore for finding suede packet inner wall, anti-chiseling down
Mechanism be micropore is controlled as far as possible to be less than suede branch diameter (8~30 μm) hereinafter, on overlay film down-proof fabric film micropore one
As need to be less than 2 μm and just have enough anti-chiseling down effects.
Other than anti-chiseling down effect is difficult to ensure, two traditional class down-proof fabric gas permeabilities are all very poor, influence human body skin
Skin is had a breath of fresh air, and hydrofuge is unsmooth, it appears very bored.If moisture is unable to Quick diffusing, natural feather easily mouldy growth bacterium and mite
Worm generates peculiar smell, allows people's allergy (the especially children and old man of constitution sensitivity).The highly dense woven fabric of fine denier FDY and overlay film are anti-drilling
Pile fabric can also generate abnormal sound in human motion.It is all these, it is all that the anti-drilling pile fabric of tradition is insoluble.
The composite material of the utility model, frivolous anti-chiseling down itself can be patted by least 5 times envelope suedes and 20 times machine-washed
Test, air-moisture-permeable, then antibiosis anti-acarien can be increased substantially by appropriate functional topical finishing, mould proof anti-smell etc. takes physiology
Comfort can effectively overcome the problems, such as that above-mentioned common packet velvet fabric encounters.The utility model is also found a kind of completely new simultaneously
Anti-chiseling down mechanism, use thermoplastic polyurethane meltblown elastomeric non-woven fabrics as anti-drilling down material, anti-suede mechanism and traditional
Anti- suede mechanism is entirely different.TPU meltblown fibers are very thin (diameter range is at 8-40 μm), and meltblown fiber web porosity is very high, most
Macrovoid is at 20-80 μm, and because the multilayered structure that meltblown fibers are accumulated, hole is also straight and smooth unlike fenestra, hole
Spatially netted connection state between gap, strainability is good, and for gas permeability considerably beyond general highly dense down-proof fabric, hole is total
Number is far longer than overlay film down-proof fabric and highly dense woven fabric, therefore the expansionary force that air pressure generates will not be in part
(at micropore) is concentrated, and can uniformly be discharged.In addition, TPU meltblown fibers surface area is big more than TPU film, adsorption capacity is strong, TPU material
Material and the coefficient of friction of suede piece are much higher than polyester filament or Tynex, and adhesion strength is strong, near the suede piece of TPU fiber internal layer
It easily is adsorbed on fiber sheath surface, the suede piece layer of these absorption itself also plays filtering and resistance to air flowing bring distal end suede piece
Hinder effect, and because porosity is very high, breathes freely uniformly and quick, so that the flow velocity that air-flow is squeezed out when suede packet is pressurized is slow, gas
Stream flows to complexity in micropore everywhere, and not single vertical cloth faces outwardly, so, the direction of motion slow with the excessive suede piece speed of air-flow
Complexity, it is whole to be parallel to cloth cover movement in opposite, up to the suede piece of mm rank be cannot pass through maximum 80 μm crowd it is microporous.
Air and suede piece can be uniformly mobile to each micropore when stress squeezes, air discharge but suede core because not no high-speed flow drive, and
No image of Buddha sub warhead equally drives entire suede piece to be pierced by TPU meltblown nonwoven layers.Here it is a kind of completely new viscous filtering anti-chiseling downs
Mechanism.
The utility model further provides for a kind of down-proof fabric, and the down-proof fabric includes that the utility model is above-mentioned
Obtained by the preparation method preparation of composite material or the down-proof fabric using the utility model composite material above-mentioned.
