Abstract
The production method of fluorescent-whitened viscose rayon includes the following steps: adding 0.5-3 portions of fluorescent whitening agent powder whose average diameter is 50-100 micrometers and 5-7 portions of water and small quantity of dispersing agent in a container, making fluorescent whitening agent powder be uniformly dispersed in water solution, pulverizing the fluorescent whitening agent by using colloid mill to make its average grain size be 0.01-3 micrometers, before spinning injecting the pulverized fluorescent whitening agent into fiber, adding 1-6 portions of fluorescent whitening agent into 100 portions of viscose fiber, uniformly mixing them to make the fluorescent whitening agent be uniformly dispersed in the cellulose sulfonate solution, then spinning and post-treatment to form bobbin.
Description
One, technical field: the present invention relates to a kind of fluorescent whitening agent, a kind of organic optical brightener that particularly in viscose rayon, adds.
Two, background technology: viscose rayon generally has slight absorption to the blue light of visible light intermediate waves one side, so having little yellow influences its whiteness, give people's outmoded unclean sense, for the method for eliminating the viscose yellowing has the chemical bleaching method, its shortcoming is that viscose yellowing place of process chemical bleaching can not all cover, and does not reach desirable whitening effect.
Three, summary of the invention: task of the present invention is to propose a kind of physics method of whitening, and whiteness is improved greatly, gives people's pure white bright-coloured sense.Technical scheme of the present invention is finished as follows, it comprises organic optical brightener, it is characterized in that: average diameter is fluorescent whitening agent powder 0.5-3 part of 50-100 micron, adding 5-7 part water and micro-dispersant is evenly dispersed in the aqueous solution fluorescent whitening agent powder, with colloid mill the fluorescent whitening agent pulverizing is made average grain 0.01-3 micron, spinning preceding injection with injector adds in the fiber, the addition control umber of fluorescent whitening agent is to add 1-6 part fluorescent whitening agent in 100 parts of viscoses, injection realizes mixing before spinning machine, fluorescent whitening agent is dispersed in the cellulose xanthate solution, is processed into tube by conventional viscose spinning process spinning post processing then.The present invention has following effect: add a certain amount of fluorescent brightening toner in fiber after, the ultraviolet ray of its energy absorbing wavelength 300-400 nanometer, with the power conversion that absorbs and give off purple or the blue-fluorescence that wavelength is the 400-500 nanometer, can remedy the blue light that is absorbed like this, improve whiteness, given people's pure white bright-coloured sense.The fluorescent brightening fibre whiteness can reach more than 90% among the present invention.
Four, the specific embodiment:
Embodiment 1: average diameter is 50 microns 1 part in a fluorescent brightening powder, add 5 parts of water and micro-dispersant, fluorescent whitening agent is evenly dispersed in the aqueous solution, with colloid mill the fluorescent whitening agent powder is made 0.05 micron of average grain, spinning preceding injection with injector adds in the viscose, by static mixing method fluorescent whitening agent is evenly dispersed in the viscose, add 2 parts of fluorescent whitening agents in 100 parts of viscoses, ultrafine dust is evenly dispersed in the cellulose xanthate solution, by the spinning of conventional viscose spinning process, be processed into tube through post processing.
Embodiment 2: average diameter is 80 microns 2 parts in a fluorescent brightening powder, add 6 parts of water and micro-dispersant, fluorescent whitening agent is evenly dispersed in the aqueous solution, with colloid mill the fluorescent whitening agent powder is made 1 micron of average grain, spinning preceding injection with injector adds in the viscose, by static mixing method fluorescent whitening agent is evenly dispersed in the viscose, add 3 parts of fluorescent whitening agents in 100 parts of viscoses, ultrafine dust is evenly dispersed in the cellulose xanthate solution, by the spinning of conventional viscose spinning process, become tube through processing.
Embodiment 3: average diameter is 100 microns 3 parts in a fluorescent brightening powder, add 7 parts of water and micro-dispersant, fluorescent whitening agent is evenly dispersed in the aqueous solution, with colloid mill the fluorescent whitening agent powder is made 2 microns of average grains, spinning preceding injection with injector adds in the viscose, by static mixing method fluorescent whitening agent is evenly dispersed in the viscose, add 5 parts of fluorescent whitening agents in 100 parts of viscoses, ultrafine dust is evenly dispersed in the cellulose xanthate solution, by the spinning of conventional viscose spinning process, become tube through processing.
