According to the invention, the long polyester silks are directly coated; wire-drawing processes with high energy consumption in the existing technology are removed; prepared 20*20-mesh polyester plastic-coated window gauzes with high fabric definition and weight per square meter lower than 85 g/sq.m. have the advantages of low energy consumption and difficulty for breaking off, and can replace glass fiber plastic-coated window gauzes which are high in energy consumption and can be broken off easily.
Description
Technical field
The invention belongs to terylene plastic-coated window screening and weave the field, especially relate to a kind of high-resolution (fabric definition high), (the square meter grammes per square metre is lower than 85g/m to little grammes per square metre
2) 20 * 20 order terylene plastic-coated window screening production technologies.
Background technology
Produce the terylene window screening and mainly contain two kinds of technologies, a kind of is to weave the production technology that afterwards sprays earlier, and another kind is that the terylene window screening of these two kinds of explained hereafter does not all possess the characteristics of high-resolution, little grammes per square metre to woven production technology behind the first extrusion molding of rove employing.
High-resolution, little grammes per square metre 20 * 20 Muchuang yarns only have glass 20 * 20 order plastic-coated window screenings at present; It need adopt the production technology of the wire drawing → twisted filament → monofilament → warping of highly energy-consuming → weave cotton cloth → finalize the design → perching; And exist not folding of product; Shortcomings such as production technology is long, and the production of high-resolution, little grammes per square metre 20 * 20 order terylene plastic-coated window screenings still belongs to blank in the industry.
Summary of the invention
The problem that the present invention will solve is through optimizing the main process control parameters of band made of plastics-coated glass fibre window screening production technology; Obtain a kind of high-resolution, little grammes per square metre 20 * 20 order terylene plastic-coated window screenings; The window screening that is prepared by the present invention has low, the advantage such as frangible not of energy consumption, can substitute not folding and highly energy-consuming band made of plastics-coated glass fibre window screening.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of 20 * 20 order terylene plastic-coated window screening production technologies comprise the steps: that polyester filament directly twists → monofilament plastic-coated → warping → weave cotton cloth → finalize the design → perching.
In the monofilament plastic-coated step of the existing technology (following abbreviation has technology now) of glass 20 * 20 order plastic-coated window screenings; Fiberglass filament after the twisting is through behind the creel; Delivering to first earlier applies in the device limit and carries out spray-painting coating; First baking oven through applying the line footpath size of long filament behind the first road plastic-coated mould and the second road plastic-coated mould control plastic-coated on the device, is sent to the paint solidification that applies on the fiberglass filament successively then in the limit; Getting into second behind the paint solidification applies in the device; Carry out spray-painting second time coating and big or small through the 3rd road plastic-coated mould and plastic-coated mould control line footpath, the 4th road successively; Then be sent to second baking oven with paint solidification; And, get into next production process through the up-coiler number of obtaining number and the required band made of plastics-coated glass fibre yarn of line footpath accords with production.
Directly with existing explained hereafter polyester filament plastic-coated screen window, it is low to exist the polyester filament brute force, is prone to the problem of broken end during the monofilament plastic-coated, and the inventor in monofilament plastic-coated step, has solved the problems referred to above through following method through a large amount of tests:
(1) reduces tension force
Creel tension force is reduced to 18N by the 28N of existing technology; Up-coiler tension force is reduced to 80N by the 110N of existing technology; Roller reduction of speed on the up-coiler, frequency conversion transfers to 30 hertz by 34 hertz that have technology now;
(2) through reducing frictional resistance and filtering out suitable plastic-coated mould:
In the monofilament plastic-coated step of existing technology, the fiberglass filament during plastic-coated needs two and applies device, altogether through the different plastic-coated mould in aperture, four roads; Just can reach the line footpath requirement that production needs, frictional resistance is big, and in the monofilament plastic-coated step of the present invention; Only need one and apply device; And only need select the aperture for use is that 0.356mm and aperture are 0.30mm plastic-coated mould, promptly only needs just can reach through twice plastic-coated mould successively to produce required yarn wire size number and line footpath requirement, has effectively reduced frictional resistance.
In addition, in the monofilament plastic-coated step of existing technology, fiberglass filament is every through twice plastic-coated mould; Get into a baking oven with regard to needs and carry out the paint solidification oven dry, four road plastic-coated moulds need be provided with two baking ovens altogether, and in the monofilament plastic-coated step of the present invention; Only need carry out the coating baking and curing and can satisfy the production demand in that the polyester filament of 200 ℃ of baking ovens after to plastic-coated is set behind the twice plastic-coated mould; And the temperature setting is lower, sees table 1, saves energy consumption more.

| The twist | The fabric definition | |
| Technology of the present invention | 45 ± 5 twist with the fingers | Good |
| Existing technology | 33 ± 5 twist with the fingers | Bad |
Advantage and good effect that the present invention has are:
1, energy-saving and cost-reducing, reduce and pollute
The band made of plastics-coated glass fibre window screening of existing technology is produced line length, energy consumption is high; The drawing plant power consumption of particularly producing fiberglass filament is high; The present invention adopts polyester filament directly to apply; Not only struck off the wire-drawing process of high energy consumption, and based on the performance characteristics of polyester filament, also reduced significantly in the energy consumption of monofilament and shaping process.In addition, because fiberglass filament is crisp, hard, a lot of capillary glasses can swim in the workshop; Cause dust pollution; And polyester filament quality of the present invention is soft, and capillary fiber is not easy fracture, therefore can slow down dust pollution and the working strength of workers in the workshop;
2, improve product specification, satisfy the high-end market demand
The high-resolution that the present invention prepares, little grammes per square metre 20 * 20 order terylene plastic-coated window screening square meter grammes per square metres are 82.55g/m
2, the plastic-coated yarn directly is 0.228mm, and is as shown in table 4 with the contrast of common window screening.Window screening of the present invention is on the basis that is suitable for, and improves comfort level and the aesthetic feeling of client when using emphatically, compare with common window screening have ultra-thin, light weight, the distinct advantages of high-resolution, satisfied the high-end market demand.
Table 4
3, reduced production cost
Can find out that from table 5 polyester filament that the present invention selected for use is compared with fiberglass filament, production cost is lower, and every km has been saved 0.03 yuan.
Table 5
