Description
Technical field
The utility model relates to air conditioner filter screen.
Background technology
Pursue green, energy-conservation and environmental protection is modern's a life idea, the domestic air conditioning decapacitation is regulated outside the changes in temperature function of air, and people need the function of air-conditioning degerming cleaning certainly, yet there is following deficiency in the conventional domestic air conditioner filter screen:
1, easily is sticky with dust, uses easy breed bacteria over a long time, and peculiar smell is arranged, bring harm for the health of human body.
2, dust impurity stops up mesh, influences the air-conditioning service efficiency, increases energy consumption.
3, remove the troublesome poeration that cleans filter screen.
In view of above-mentioned condition, air-conditioning research and development institution has researched and developed that a kind of air-conditioning just can be cleaned with water automatically before start, degerming and discharge outdoor device, and the air conditioner filter screen material has been proposed also that matter is thin, Air permenbility is big, high temperature resistant, adapted to brand-new functional requirements such as subsequent chemistry processing.
At first, owing to will realize the optimal air regulating effect, reach purpose of energy saving, it is maximum that the Air permenbility of degerming clean air conditioner filter screen will reach.Secondly, clean with water in the process at filter screen, the intertwined point of screen cloth can not produce displacement, and the fabric big concerning mesh, that the silk footpath is thin, easier generation displacement.Moreover, to guarantee that also deformation does not take place filter screen in preparation process.Yet traditional domestic air conditioning filter screen can not satisfy above-mentioned requirements.
The utility model content
The purpose of this utility model overcomes the problems of the prior art exactly, and a kind of air conditioner filter screen is provided.
For solving the problems of the technologies described above, the utility model provides following technical proposals:
A kind of air conditioner filter screen, for polyester fiber is weaved the filter screen that forms through the projectile shuttle weaving process, the fabric tissue of filter screen is a plain weave, and the aperture of filter screen is the 297-311 micron, and the silk footpath is the 51-57 micron, and the intertwined point of filter screen screen cloth is fixedly connected.
Further, the warp-wise density of filter screen be the 27.44-28.56 root/centimetre, latitudinal density be the 26.6-29.4 root/centimetre.
The aperture of the utility model filter screen and the configuration design of silk footpath break through tradition, fabric tissue is a plain weave, the warp-wise density of filter screen be the 27.44-28.56 root/centimetre, latitudinal density be the 26.6-29.4 root/centimetre, this design is ensureing that its wire side is flat very, the robust while, can improve its effective sieving area, its sieving area is increased to more than 70% on original 44.4% basis, increase by 60%.
Screen material of the present utility model is selected polyester fiber for use, and this material mainly is that main component is poly terephthalic acid second two fat by organic binary acid and the dihydroxylic alcohols high polymer through polycondensation reaction.This fiber initial modulus is higher, and not yielding under little load effect, the recovery capacity of distortion is good.The big molecule of polyester fiber is firm linear molecule, and the degree of crystallinity height does not have hydrophilic group in the inner big molecule, and air conditioner filter screen is selected polyester fiber for use, utilizes these characteristics of this fiber just.Because the silk footpath is thinner, after obtaining repeatedly cleaning, the filter screen consistency requires the intensity of material will reach 4.0～5.2CN/dtex, percentage elongation 18～25%, and boiling water shrinkage 8～12%, and bar is done evenly.
Further, the utility model adopts the polyester fiber with ad hoc structure, and this polyester fiber comprises top layer and nexine, is lower than the polyester fiber of nexine fusing point for the top layer fusing point.Preferable, the top layer fusing point of described polyester fiber is 256-265 ℃, the nexine fusing point is 150-160 ℃.Because the air conditioner filter screen mesh is big, and in order to increase the sieving area, the utility model has been selected the filament footpath, and clean with water in the process at filter screen, the fabric that mesh is big, the silk footpath is thin can easier generation displacement, the top layer fusing point of the polyester fiber sectional area that the utility model adopts is lower than nexine, when fabric thermal finalization, when reaching uniform temperature, melt on the top layer, the cooling after coagulation is in the intertwined point, this can overcome common coat binding material fixedly the mode of the intertwined point screen surface layer performance that can produce change, still keep the characteristics of polyester fiber.The commercially available acquisition of this kind polyester fiber.
Air conditioner filter screen of the present utility model adopts following method to make:
1. polyester fiber is adopted the projectile shuttle weaving process to make filter screen;
2. thermal finalization: under the tension force condition with 1.5-2.5 centimetre of filter screen broadwise increase, under 190-200 ℃ the temperature, handle 4-6 second;
3. clean.
Because the material mesh is big, the silk footpath is thin, and the later stage also need heat treatment, this just must increase its woven difficulty, mesh is even, the aperture is accurate in order to obtain, wire side is flatly endured, robust filter screen, and the projectile shuttle weaving process is carried out following improvement:
During the warp let-off, adopt double end or bull worm and gear, to be fit to weaving of low-density, large-mesh filter screen.And adopt single through axle, to overcome the situation of double ends beam warp thread tension difference.
When beating up, 4 degree are selected at the angle of beating up for use, and this design can increase the length that fabric forms the district, improve the even of silk thread arrangement.The preferred reed wire that adopts 7mm.
Preferable, select little opening process, adopt little opening process can reduce the loss of organizine intensity.
Preferably, 5 pieces/centimetre of the organizine density of heald frame, heald frame number of pages are 6 pages.
The purpose of thermal finalization is for fixing intertwined point, before fabric fibre enters vitrification point, under certain tension force condition, through 4-6 high-temperature process second, can make the molecules align of fiber reach stable state.During thermal finalization, adopt fixing the moving ahead of broadwise can guarantee that deformation does not take place filter screen with warp-wise.Preferable, thermal finalization filter screen gait of march is 30 meters/minute.
Air conditioner filter screen of the present utility model, the sieving area is compared traditional air conditioner filter screen has increased about 60%.The filter screen mesh that makes is even, the aperture is accurate, wire side is flat very, sturdy and durable, is used for the air-conditioning preparation and can save energy environmental protection.
