Abstract
The invention discloses a kind of application of new ultra-violet absorbent in the arrangement of fabric UV resistance, belong to function additive technical field.Ultraviolet absorber is made into finishing fluid first and individually carries out UV resistance arrangement to cotton fabric by the present invention.Cotton fabric UV resistance effect after arrangement is preferable, fastness to washing is preferable, still can reach UPF > 40 washing 30 times or more, and UV resistance fabric other performance such as ultimate strength, elongation at break, recovering of folds angle have not significant impact.The present invention is also by ultraviolet absorber and nano-titanium dioxide composite finishing fabric, by the way that by the method for physical shielding and chemical absorbing combination, the UV resistance effect of the fabric after arrangement becomes more preferable.
Description
Technical field
The present invention relates to a kind of application of ultraviolet absorber in textile finishing, belong to function additive technical field.
Background technique
Since industrial expansion brings environmental pollution, the discharge of a large amount of freon class solvents, so that atmosphere ozone layer
It is constantly destroyed by loss, the ability of Ultraviolet radiation absorbing weakens significantly, and tellurian ultraviolet radiation increases sharply, and gives the earth
The health care belt of biology carrys out various injuries.In face of increasingly severe environmental problem, people start to pay attention to the protection of environment,
More pay attention to spontaneous protection.
The features such as cotton fabric is because of its excellent wearing comfort, sucting wet air permeability, it is welcomed by the people, it is that demand is bigger
A kind fabric, but phenyl ring is free of in the structure of cotton fiber, and there is the rough form of Longitudinal Warping, ultraviolet light is easy to penetrate
Cotton fabric, so carrying out UV resistance arrangement to cotton fabric is particularly important.
The ultraviolet light of strong, the selective absorption high-energy of ultraviolet absorber the energy, (wavelength in the form of other low energy
Longer light or heat) release, to avoid injury of the ultraviolet light to human skin.Domestic common ultraviolet absorber master at present
It to be salicylic acid esters, benzophenone, benzotriazole etc., but salicylic acid esters finishing agent fusing point is low, Yi Shenghua, absorption
Coefficient is low, the easy yellowing of fabric after arrangement；Benzophenone is expensive, sometimes easy yellowing；Benzotriazole absorbs 300-400nm
Light, it is small to cotton fiber affinity, be not easy fixation, easily spread, fastness to washing is low.
Summary of the invention
The problems such as in order to solve low above-mentioned fastness to washing, yellowing, the present invention provides a kind of ultraviolet absorbers to knit in cotton
Application in object anti UV finishing, for structure such as shown in (1), which has preferable UV resistance effect, it absorbs ultraviolet
It, can be by being converted back to ground state in ultrafast photoisomerization mode, effectively by the energy of ultraviolet light after line reaches excited electronic state
Amount is transmitted in environment, has preferable UVResistant effect and washability through its cotton fabric after arranging, moreover it is possible to effectively prevent fabric
Yellowing.Meanwhile the present invention also provides a kind of compound method for covering with paint, lacquer, colour wash, etc. material finish fabric of ultraviolet absorber and nano-titanium dioxide,
The UV resistance better effect of fabric after being arranged by way of combining physical shielding and chemical absorbing ultraviolet light.
The present invention provides a kind of fabric finishing method, the method utilizes the ultraviolet absorber of chemical formula (I).

Into finishing fluid, salt is added, is slowly ramped to 90 DEG C, keeps the temperature 60min, takes out fabric, washes, drying.In the method, it surveys
Determine ultraviolet absorption effect, UPF value is 65 ± 5；The performance of fabric after arranging is determined simultaneously, the results showed that UV resistance is arranged to knitting
Breaking strength (N), elongation at break (%) and the recovering of folds angle (°) of object have no significant effect.
In another embodiment, the method is that compound covering with paint is made in ultraviolet absorber and nano-titanium dioxide
Material expects finish fabric using compound covering with paint.
In one embodiment, the compound preparation for covering with paint, lacquer, colour wash, etc. material: by nano-titanium dioxide ultrasonic disperse in ultraviolet suction
It receives in agent aqueous solution, is then added into polyacrylate dispersion, after mixing in 70-80 DEG C of stirring 5-10h, obtains anti-purple
The compound covering with paint material of external form；Wherein, the mass ratio of nano-titanium dioxide and polyacrylate dispersion is (0.15-0.40g): (20-
30g)。
In one embodiment, ultrasonic disperse power is 100-500W, time 50-20min.
In one embodiment, the speed of 70-80 DEG C of stirring is 300-600rpm.
In one embodiment, described to expect finish fabric using compound covering with paint, specifically: padding (30-100%) → baking
Dry (80-110 DEG C, 3-10min) → bake (150-180 DEG C, 1-3min).
Beneficial effects of the present invention:
(1) ultraviolet absorber finish fabric of the present invention using formula (1), fast response time under the ultraviolet absorber illumination,
Fabric UV resistance effect after arrangement is good, is not easy yellowing.
(2) method for sorting of the invention, fastness to washing is preferable, according to national standards the anti-purple of GB/T18830-2009 textile
The UV resistance effect of outside line performance test finish fabric, UPF > 50 of fabric after arrangement still are able to after 30 washings
Reach UPF > 40, reaches the requirement of antiultraviolet product.
(3) present invention also expects finish fabric using the compound covering with paint of ultraviolet absorber and nano-titanium dioxide of formula (1), has
Better uvioresistant and anti-yellowing effect.
