Description
Technical Field
The invention belongs to the technical field of fabric, and particularly relates to an anti-static flame-retardant double-layer fabric made of fluorescent orange and a preparation method of the fabric.
Background
The flame-retardant clothes are pet clothes, are flame-retardant, fluorescent and antistatic, and have a wide market if the flame-retardant clothes are treated by water and acid and alkali resistance. However, the flame-retardant cloth with yellow fluorescence is more popular in the market. Because many textile fibers can be dyed to reach fluorescent yellow and have the function of flame retardance. However, the single color variety makes the market popular, and the design and production of fluorescent orange flame-retardant cloth are very difficult, so the market is almost blank. The reason is that only polyester fibers (namely polyester fibers) are used as dyed fiber materials which can reach the standard of fluorescent orange European Union EN20471, and only disperse fluorescent orange (beta value brightness is 0.4) dyed by fluorescent disperse dye can reach the standard of EN20471, but because the polyester is inflammable, the combustion temperature is very high and reaches more than 800 ℃. The fused terylene colloid remains on other fiber skeletons to be continuously combusted, which is enough to melt, carbonize and cut textile fibers. If the flame-retardant materials such as phosphorus and the like are added into the polyester fiber used alone before melt slicing and spinning to prepare the flame-retardant polyester, molten holes and molten drops can be generated at very low temperature (more than 300 ℃) during combustion, so that the damage to human bodies is caused, and the purpose of protection cannot be achieved.
The present invention has been made in view of the above circumstances.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides the fluorescent orange antistatic flame-retardant double-layer fabric and the preparation method thereof, the fabric has bright fluorescent orange color through the comprehensive action of all raw materials, has good flame-retardant effect and better antistatic effect, and meets the EN20471 standard of European Union.
The invention provides a fluorescent orange antistatic flame-retardant double-layer fabric, which comprises a surface layer and an inner layer, wherein the surface layer comprises surface layer warp yarns and surface layer weft yarns, the inner layer comprises inner layer warp yarns and inner layer weft yarns, the surface layer warp yarns and the surface layer weft yarns are manufactured through a three-over-one-under weaving method, the inner layer warp yarns and the inner layer weft yarns are manufactured through a two-over-one-under weaving method, the surface layer and the inner layer are connected through warp and weft yarns in a vertically jumping mode, and a plurality of conductive fibers are arranged on the surface layer along the directions of the surface layer warp yarns and the surface layer weft yarns.
The surface layer warp yarns and the inner layer warp yarns respectively have a group which does not move according to the movement rule, the surface layer warp yarns are hooked with the inner layer weft yarns, and the inner layer warp yarns are hooked with the surface layer weft yarns to enable the whole cloth to be connected into a whole. Five warp yarns or weft yarns are in a circulation, namely every four warp yarns or weft yarns have a yarn jumping up and down, and the warp yarns or weft yarns are covered by other normal weave yarns due to small weave points and cannot be basically seen, so that the whole fabric looks like a piece of cloth.
Further, the surface layer warp yarn is 100D polyester yarn, and the surface layer weft yarn is 30s/2 strand modacrylic.
Furthermore, according to the mass percentage, the polyester yarn in the surface layer is 28-32%, and the modacrylic is 68-72%.
Furthermore, the polyester yarn in the surface layer is 30 percent, and the modacrylic is 70 percent.
The surface layer warp yarns are made of the material because the bright fluorescent orange color can be achieved by dyeing and dispersing the polyester yarns, the fluorescent orange standard of European Union EN20471 can be achieved, and a satisfactory color effect can be achieved by placing the polyester yarns on a surface layer.
The polyester filament is also called polyester fiber, is totally called poly (ethylene terephthaloyl) and is spun out through a plurality of spinneret holes (such as 92F or 76F) at a high-temperature melting spinneret, and the tortuosity is increased after the polyester filament is drafted, thermally bent and shaped. The bending degree reaches 10-15%, and the polyester yarn is low stretch yarn. If a high-temperature is given every 1cm, the polyester yarns are bundled, and the polyester yarns have a knot at the position to become interlaced yarns. The method has great convenience for the subsequent dyeing and weaving, and the polyester yarns are not broken by fluffy single yarns any more and are easy to dye and weave.
The polyester yarn is made to a fixed length, namely the gram weight of 1000 m of the polyester yarn is used as the number (TEX), and 100D means that the polyester yarn has the mass of 100 g when the length is 1000 m.
Based on the characteristics of bending and fluffiness of the terylene threo, the cloth cover has a plump fluorescent color covering effect, and the brightness of the whole cloth is up to the standard.
The surface weft yarn is Japanese nylon which is pure modacrylic and has the thickness of 1000 meters and about 39 grams, and the modacrylic is also called modified acrylic fiber and is formed by copolymerizing acrylonitrile monomer and vinyl chlorine-containing compound containing flame retardant elements. Chlorine is a key element for flame retardance (vinyl chloride is a difficult-to-burn product, and the oxygen limit index reaches 65%), and the compound and acrylonitrile are subjected to graft copolymerization to form modified modacrylic, and the oxygen limit index of the synthesized series modacrylic is 30-34%.

When the material is used alone for flame-retardant clothes, the viscous state temperature is too low, and the temperature is too low, so that the melting shrinkage is easily generated, and the flame-retardant clothes with high quality are not favorably made. However, due to the characteristics of high flame retardance and low melting point of the material, the material can be melted in advance before the melting point of the polyester, the melted flame-retardant silk colloid is tightly attached to the warp polyester yarns, the polyester fibers can be tightly adhered and surrounded before the polyester yarns are ignited at 500 ℃, and finally the flame-retardant silk colloid is co-melted with the polyester fibers to form a non-combustible colloid, wherein when the designed 18.5 # doubled yarn of the modacrylic yarn is the thickness of the # 39 polyester yarn. The mass of the modacrylic per square meter of area is far greater than that of the polyester yarns, and if the polyester yarns cannot be burnt and have the thickness of 100D according to the density of 32 warp threads/cm, the weight of the polyester yarns per square meter is 33 g; if a 18.5 gauge doubled yarn, i.e., a 37 gauge yarn, is used in the design of the modacrylic weft yarn, the modacrylic yarn has a square meter weight of 92 grams per square centimeter.
The flame-retardant modacrylic molten colloid of 92 grams per square meter wraps 33 grams of polyester burning colloid to achieve the purpose of later-stage colloid mixed melting into an adhesive film, the adhesive film is coated on a burning point of the second base fabric, the flame-retardant modacrylic molten colloid and the second base fabric slowly vaporize along with the increase of burning time, the burning time is also finished, the burning flame is temporarily blocked by the thick flame-retardant tissue of the base fabric, the safety of a human body is protected within a certain time, the purpose of flame retardance is achieved, and the standard of flame-retardant protective clothing is also met.
The surface layer fluorescence effect and the flame retardant effect are a pair of contradictory integers and are mutually restricted, and when the proportion of the polyester yarns is large, the fluorescence effect is good, and the beta value is high; when the proportion of the polyester yarns is small, the fluorescent effect is not good, but the flame retardant effect is good, and the inventor determines that the flame retardant property and the fluorescent effect of the fabric prepared according to the proportion of the surface layer warp yarns and the surface layer weft yarns are optimal through a large number of tests.

Test example 1 relationship between the ratio of the surface layer warp raw material and the performance of the produced fabric
The double-layer fabric is prepared in the same way as in example 2 except that the proportion of the polyester yarns and the modacrylic in the surface layer warp yarns is changed, and the properties are shown in table 1.
TABLE 1
As can be seen from the table 1, the surface layer fluorescence effect and the flame retardant effect are a pair of contradictory integers and are mutually restrictive, and when the proportion of the polyester yarns is large, the fluorescence effect is good, and the beta value is high; when the proportion of the polyester fibers is small, the fluorescent effect is not good, but the flame retardant effect is good, and through a large number of experiments, the inventor finds that when the proportion of the polyester fibers and the modacrylic is 30 percent and 70 percent, the flame retardant effect is best, but the fluorescence beta value is slightly low. But the fluorescence just meets the standard: the beta value is more than or equal to 0.4, therefore, the optimal ratio of the terylene to the modacrylic is 30 percent and 70 percent.
Test example 2 flame retardant relationship between thickness and square gram weight of surface layer warp yarns, surface layer weft yarns, inner layer warp yarns and inner layer weft yarns and prepared fabric
The fabrics were prepared in the same manner as in example 2 except that the thicknesses and the square gram weights of the surface layer warp yarns (surface warps), the surface layer weft yarns (surface wefts), the inner layer warp yarns (inner warps) and the inner layer weft yarns (inner wefts) were changed, and the performance of the tested fabrics is shown in table 2.

X1 0.535Y1 0.376； X2 0.594Y2 0.315
X3 0.510Y3 0.391； X4 0.690Y4 0.311

As can be seen from Table 3, the orange fluorescence test of the fabric prepared by the dye formula disclosed by the invention meets the EN2041 standard, the formula 1 is better, the beta value after exposure to the sun is still on a brighter coordinate, and the formula 2 can be selected but is dangerous. After the colored light of the yarn is prepared into cloth, the cloth is influenced by darker surface wefts, and the integral fluorescence degree is slightly reduced, so the No. 1 formula is the best.

The fabric is prepared in the same way as in example 2 except that the proportion of the surface layer weft yarn dye is changed, the performance of the fabric is examined and shown in table 4, and the fluorescence performance test is the same as in test example 3.
