Description
Technical field
The invention belongs to textile technology field, particularly to a kind of photochromic viscose rayon and preparation method thereof.
Background technology
The mankind find the photochromism history of existing more than 100 year.Photochromic material, refers to the class material by color can be occurred after light source activation to change.Photochromic some compound molecular structure under the light action of certain wavelength and intensity that refers to can change, thus causes its corresponding change to the i.e. color of absorption peak of light, and this change is usually reversible.
Photochromic material has the advantages that variable color is sensitive, bright in colour, but easily affected by environmental factorss such as temperature, illumination, pH value and oxygen, thus cause aoxidizing deterioration, fatigue durability variation, and part photochromic material does not has affinity to fiber, have impact on its application in textile processing.Photochromic material is combined with fabric, the earliest and the easiest method is stamp and staining technique.With the color-changeable fabric of this technological development, photochromic material is easy to be directly exposed in external environment, causes discoloration to lose efficacy, and the variable color life-span is the shortest.Along with the fast development of microcapsule technology, photochromic material is made microcapsule so that it is separate with chemical environments such as acid, alkali, air and impurity, substantially increase the fatigue durability of photochromic material, extend service life.
In recent years, a lot of research has been carried out both at home and abroad at photochromic material and application aspect thereof, such as, CN201310746498.1 patent discloses a kind of method that directly interpolation micro encapsulation photochromic powder prepares light-induced variable colo(u)r streak in viscose glue: in the viscose glue after refined, the ratio according to weight ratio 8%-20% adds micro encapsulation photochromic powder, directly preparing can be with photochromic line, re-use this line and make photochromic Clothes decoration articles, make product category pattern the most various, and technique is greatly simplified.Light-induced variable colo(u)r streak its color fastness to washing and water permeability resistance etc. of utilizing this scheme to obtain are improved, but the problem not accounting for causing light-induced variable colo(u)r streak strength to reduce after micro encapsulation photochromic powder adds viscose rayon to, it is impossible to ensure the spinnability of viscose rayon.
Viscose rayon belongs to regenerated celulose fibre, its good hygroscopicity, easily dyeing, antistatic, the softness that is of close texture, be smooth to the touch, good permeability, comfortable and easy to wear, after dyeing or stamp, bright in colour, color fastness is good, it is prone to make underwear, coat and various drapery, is also the common used material making wire rod.Because of the molecular configuration of himself determine its dry state, hygrometric state strength ratio relatively low, some inserts (photochromic micro-encapsulation material) are added again such as inside, fibre structure is impaired, thus causes the dry state of fibrous material, hygrometric state strength lower, it is difficult to meets fabric manufacture and uses requirement.
Summary of the invention
It is an object of the invention to provide a kind of component photochromic viscose rayon simple, rational, additionally provide its corresponding preparation method simultaneously.
For reaching above-mentioned purpose, the technical solution used in the present invention is: a kind of photochromic viscose rayon, is made up of viscose glue, photochromic micro-encapsulation and fiber enhancer.
In described viscose rayon, photochromic micro-encapsulation content is 1～20wt%, and fiber reinforcement agent content is 0.1～10wt%.
Mean diameter≤2.0 μm of described photochromic micro-encapsulation.
Described fiber enhancer is water-soluble cellulose derivative, polyacrylamide or polycarboxylate.
Described cellulose derivative is cellulose esters or cellulose ether, and described polycarboxylate is polyacrylate.
Described cellulose esters is selected from cellulose ethanoate and cellulose acetate butyrate.
Described cellulose ether is selected from methylcellulose, carboxymethyl cellulose, hydroxyethyl cellulose, cyanethyl cellulose, hydroxypropyl cellulose and hydroxypropyl methyl cellulose.
Described polyacrylate is selected from polymethyl acrylate, polyethyl acrylate, poly-2-methyl methacrylate and poly-ethyl 2-methacrylate.
The preparation method of described photochromic viscose rayon, comprises the following steps: 1) by formation dispersion agent emulsion soluble in water to photochromic micro-encapsulation and fiber enhancer；2) dispersion agent emulsion is added in viscose and mix；3) acid bath spinning moulding, obtains photochromic viscose rayon product.
In described step 1), the concrete preparation method of dispersion agent emulsion is: first that fiber enhancer is soluble in water, adds photochromic micro-encapsulation mixing.
The present invention uses photochromic micro-encapsulation, colour-changing agent can be protected well not contact with the highly basic in viscose rayon manufacturing process, strong acid, it is to avoid chemical reaction occurs.
Owing to the intensity of viscose rayon is relatively low, after adding photochromic micro-encapsulation, its intensity can be lower, the present invention adds fiber enhancer and is contemplated to effectively overcome this defect, improves the intensity of viscose rayon, makes the photochromic viscose rayon of the product prepared disclosure satisfy that the requirement of spinning.The mechanism strengthened is: viscose rayon is each other with 1 by D-glucopyranosyl, a kind of homogeneous macromolecule that 4-β glycosidic bond is formed by connecting, cellulosic molecule is in addition to two end groups, each glucosyl group has three hydroxyls, cellulose reinforcing agent can participate in the hydrogen bonded of cellulose, the hydrogen bond number of self-assembling formation between supplement fiber element molecule, this is the one " chemical hydration effect " of cellulose fibre system, chemical hydration effect can be effectively increased the internal stress of fiber.
During photochromic micro-encapsulation adds spinning viscose to, fiber enhancer is added in viscose glue together as photochromic micro-encapsulation suspension dispersive agent in spinning liquid, after mixing, spinning, the fiber of molding is made up of prezenta/photochromic micro-encapsulation/fiber enhancer trielement composite material, this fiber entirety variable color is uniform, strength can meet or exceed conventional viscose rayon, meets the demand that fabric manufactures.
Photochromic capsule can effectively eliminate the reaction environment harmful effect to photochromic material, refers to be coated on by photochromic material inside the microcapsule that cyst wall is transparent, and preparation has the variable color microcapsule of photochromic characteristic under ultraviolet and daylight.
The invention have the benefit that
1, the photochromic viscose rayon of the present invention not only has photochromic sensitive effect, and product is soft smooth, outward appearance is beautiful affable, there is extraordinary easing characteristic and good photochromic properties, be the ideal material making the products such as fashion curtain, stage curtain, art clothing, anti-false trademark pattern, outdoor mini variable color gaudy attire.Owing to this fiber optically variable effect is sensitive, the clothing of making have the stealthy effect of chameleon, it is also possible to as army's field operations protection dress fabric.
2, the fiber of molding is made up of prezenta, photochromic micro-encapsulation, fiber enhancer trielement composite material, and this fiber entirety variable color is uniform, and strength can meet or exceed conventional viscose rayon, is fully able to meet the manufacture of fabric and use demand.Additionally, due to such chameleon fibre be not required to again through after dyeing and finishing process, the fabric of different purposes can be manufactured directly to, so being also not required to consider the problem of shade fabric uniformity in dyeing course.
3, the present invention is by adding fiber enhancer in viscose rayon, can be effectively improved fibrous material dry state, the hygrometric state the lowest shortcoming of strength, enhance the stability of viscose rayon, it is ensured that the spinnability of fiber, reach the requirement needed for fabric.
4, the preparation method of the present invention is simple, workable, it is simple to large-scale industrial production.
