Its steps are: To use surface treatment nano-powder and disperser mix in remove-ion water, stir them evently to produce nano-surface-treatment solution; to mix lip idol into nano-meeker and stir them to produce nano-meek solution: To use benzophenone mix acetic ethylene lipid to produce nano-photosensitive solution. To put pre-treated fibre in the nano-pholosensitive solution, and irradiate them with ultra violet ray; put these fibres into the nano-treatment solution, adjust pH value after soak them. Then irradiate them with ultraviolet ray again; to treat them with nano-meek solution, washing, drying, produce the surface has nano-crystallization function fibre.
Description
Technical field
The present invention relates to a kind of fiber surface treatment process method, especially a kind of fiber surface nano-crystallization treatment process.
Background technology
Conventional fiber (cotton, numb, thread, mao) surface treatment, the various treatment fluids of general employing, finish with traditional rear finishing duplex technology, fiber with this method processing, exist the processing raffinate to have pollution, quality of fiber and performance can not adapt to deficiencies such as modern fabrics requirement, as antibiotic, antistatic, anti-flaming function.In order to change these defectives, satisfy the requirement of fabric, the method for various fiber post processings is arisen at the historic moment.Especially nanometer technology has played positive facilitation in the application of fiber post processing to improving quality of fiber and performance.Old net for catching beasts is bright to wait " a kind of nanostructured high-specific surface area chemical fibre and preparation method thereof and the application " of invention (open/notification number: CN1316553), its principal character is that the chemical fibre surface has nano level micropore, and by in chemical fibre raw material, adding nano particle, decompose with chemical solution again after the shaping and form, this invention only is confined to make cigaratte filter, the industrial products of nonwoven fabric; Japan Patent Laid-ope sho-52/92000 and Hei-07/343169 are to have the post-processing approach of the particle of antibacterial action attached to fiber surface.
Above-mentioned patent only is attached to fiber surface with nano particle or material after-treatment, the fiber that this method is handled is along with the variation of environmental condition, the technogenic influence of weaving operation and wearing and tearing and the washing in the use, and its surperficial anchorage, physics, mechanical property all will be affected.
Summary of the invention
The objective of the invention is to utilize UV-irradiation, make fiber in containing photosensitizer and Nanosurface Treatment Solution, carry out the photo-grafting reaction, solve the problem of the functionalization functional group of fiber surface generation, thereby a kind of fiber surface nano-crystallization treatment process is provided with chemical bond form strong bonded.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is to add deionized water with nano functional surface conditioning agent and dispersant to carry out the dispersion and emulsion stirring, makes the nano functional surface processing solution; With nanometer softener and fatty alcohol, put in the stirred tank and stir, make the submissive solution of nanometer; Add vinylacetate with nanometer photosensitizer benzophenone, put in the stirred tank and stir, make nanometer photoactivate solution; To introduce the optical processing chamber through pretreated fiber, and place the nanometer photoactivate solution of treatment trough, handle, and the fiber behind the ultraviolet radiation will be placed the nano functional surface processing solution of treatment trough, flood with fatty acid for adjusting pH value with UV-irradiation; Then the fiber after the impregnation process is carried out UV-irradiation once more, and by the treatment trough of the submissive solution of nanometer is housed; With the fiber wash after the submissive processing, oven dry, make the functional fibre that the nano surface crystallization is handled again.
Wherein said nano functional surface conditioning agent is antiseptic nano powder or nano-anti static powder or nano flame retardant powder; Described fiber is cotton or fiber crops or silk or hair.
Above-mentioned fiber surface nano-crystallization treatment process, this technology in turn include the following steps (weight portion):
(1) get 1～10 part of nano functional surface conditioning agent, 0.5～2 part of dispersant adds deionized water again, be mixed with concentration and be 3～8% solution, stir 10min with high-shearing dispersion emulsifying machine down at 60 ℃～75 ℃, speed 8000～10000rpm, it is stand-by to make the Nanosurface Treatment Solution;
(2) get 50～70 parts of nanometer softeners, add 5～10 parts of fatty alcohols, put in the stirred tank, under 50～100rpm, stir 20～30min, make the submissive solution for later use of nanometer;
(3) get 1～10 part of nanometer photosensitizer benzophenone, add 0.5～2 part of vinylacetate, put in the stirred tank, under 50～100rpm, stir 20～30min, make nanometer photoactivate solution for later use;
(4) will introduce in the treatment trough of the nanometer photoactivate solution that above-mentioned (3) are housed through pretreated fiber, by UV curing apparatus, ultraviolet wavelength 180～190nm, light radiation 1～10min;
(5) the Nanosurface Treatment Solution treatment trough that will place above-mentioned (1) to make through the fiber of light radiation, with fatty acid for adjusting pH value to 6～8, under 20 ℃～50 ℃, dipping 1～8min;
(6) carry out UV-irradiation, 1～8min once more;
(7) in the solution-treated groove with the nanometer softener of illumination fiber above-mentioned by being equipped with (2) later, temperature is 30 ℃～40 ℃, keeps 1～5min;
(8) with the fiber wash after the submissive processing, import drying unit at last, bake out temperature is 40 ℃～120 ℃, drying time is 10～20min.
The innovation part of the invention process technique scheme is to make nano particle to be uniformly distributed in fiber surface, because UV-irradiation, make the crystal boundary on fibrous material surface produce staggered two-dimentional phase region, the interface that each phase region and two-phase make up is nano-scale, and because light radiation forms the nanometer crystal layer; Nanocrystal combines with the chemical bond form with the two-dimentional phase region of fibrous material surface crystal boundary, but not simple physical absorption.The fiber of the textile auxiliary post processing that the fiber after therefore nano-crystallization is handled is different and traditional has effects such as unconventional lasting, wash resistant.Simultaneously, whole technical process is pollution-free, nuisanceless, helps environmental protection and human health.By the SEM photo of Fig. 1, Fig. 2 as seen, a kind of nano surface crystallization layer of silk fiber is evenly distributed, in conjunction with good.
Description of drawings
Fig. 1 is the SEM photo on untreated silk fiber surface, its smooth surface, and the Nanosurface handled thing is difficult at surface formation crystal layer.
Fig. 2 is the SEM photo on the silk fiber surface after handling, and radiation energy makes the cracking of fiber surface strand, oxidation, crosslinked, makes the crystal boundary generation of fiber surface be staggered to form firm crystal layer.
