Abstract
The present invention provides a powdery fluorescent whitening agent composition with easy dispersion for textile industry. The composition comprises fluorescent dye, non-ionic surface active agent, anion surface active agent, naphthalene sulfosalt, lignosulphonate anion dispersing agent, preservative, dust-proofing agent and inorganic salt. The composition can be stored for a long time, has excellent dispersivity in water, and does not have phenomena such as vat sticking, roll sticking, uneven dyeing, etc., in the dyeing process.
Description
The present invention relates to a kind of powdered fluorescent composition as whitening agent and its preparation method that industrial textile is used.
Usually the commercially available white dyes that is used for textiles is aqueous prescription, water content even high wherein to 90%, and these prescriptions exist in the standing storage process inevitably to be afraid of to freeze, takes place to precipitate and defective such as peculiar smell may occur.Particularly in use, this liquid fluorescent whitening agent product easily produces sticking cylinder and look flower.In order to make aqueous liquid fluorescent whitening agent stable, these prescriptions usually are transferred to slightly acidic, pH=4-7, but this brings etching problem simultaneously, even like this, and its validity period also only 6 months.In addition, also disadvantageously wherein the concentration of actives is lower for aqueous liquid brightener formulations, generally is lower than 25%, and the thickness otherwise these prescriptions can become is difficult to processing.Moreover the liquid fluorescent whitening agent product also is difficult for transportation, packing cost height.
Most fluorescence dye is water-fast, and therefore when being mixed with aqueous fluorescent dye dispersion, dispersion agent is indispensable necessary component.Aqueous fluorescent liquid dye dispersion liquid all has report in many patent documentations.Having reported a kind of in the European patent EP 321393 is the fluorescent liquid dye dispersion liquid of dispersion system with anion surfactant, cats product or nonionogenic tenside and N-vinyl pyrrolidone and 3-vinyl propionic acid multipolymer.German patent DE 2734204 discloses fluorescent dye dispersion, and it adopts vinylformic acid and styrol copolymer or vinylformic acid and copolymer-maleic anhydride as dispersion agent and the dispersion system formed with ethylene glycol, trolamine etc.The common drawback of above-mentioned dye dispersion liquid is the influence that is subject to soda acid, and causes quality product to descend.The method that does not wherein openly prepare powdered fluorescent composition as whitening agent.
Disclose a kind of liquid brightener formulations of shelf-stable among the CN96111498.3, wherein mainly contained white dyes, inert proton-organic solvent and water.The method that does not wherein openly prepare powdered fluorescent composition as whitening agent.
In existing liquid, aqueous dye dispersion liquid, be difficult to will dissimilar fluorescence dyes for example the fluorescence dye of non-ionic type and anionic be mixed and be in the same place precipitate because they easily form when being mixed.Once the someone attempted to study preparation powdered fluorescence dye product, but because of the dispersion problem of not resolving in water, and succeed.
Along with the development of industrial textile, press for a kind of stable easy dispersive powdery fluorescent whitening dyes product.
The object of the invention is exactly the defective that overcomes existing liquid, aqueous white dyes product, and a kind of powdered fluorescent composition as whitening agent of easy dispersive stable storing is provided.
Another object of the present invention provides a kind of powdered fluorescent composition as whitening agent that does not have the dyeing homogeneous of sticking cylinder, roll banding and look flower phenomenon.
