Description
Technical field
The present invention relates to a kind of production method of ultraviolet prevention fiber.
Background technology
In general, suitable ultraviolet ray is useful to human body, and it can promote the synthetic of vitamin D, rickets is had inhibitory action, and have sterilization.But in recent years; because the chlorofluorination hydrocarbon compound in fluorine Lyons and so on is discharged in human being's production and life in large quantities; the umbrella that makes the earth is that atmosphere is destroyed day by day; at terrestrial pole and the sky, China Qinghai-Tibet Platean the ozone cavity has appearred particularly; the guard circle of the earth is that the ozone layer attenuation is thinning; the amount of ultraviolet irradiation that arrives ground increases, and the disease that causes because of excessive ultraviolet ray irradiation gets more and more.Generally speaking, human body skin can be accepted ultraviolet safe amount of radiation every day should be in 20kJ/m2, and the amount of radiation that ultraviolet ray arrives ground about 40～60kJ/m2 during the cloudy day, about 80～100kJ/m2 when fine, can reach 100～200kJ/m2 during scorching sun in hot summer days, common dress material generally about 50%, does not reach requirement of shelter to ultraviolet screening rate far away.In addition, long-term ultraviolet ray irradiation also can cause fading of textiles and aging.Therefore, be necessary textiles is carried out anti-ultraviolet finishing.
When illumination was mapped on the object, a part was reflected by body surface; Part is absorbed by object; Other then see through object.Fiber and goods with ultraviolet protection function, when UV-irradiation, except wherein the hole of a part from fabric sees through (its transit dose tissue of looking fabric with thickness etc. different), not not reflected by ultra-violet protecting agent of other, selectively absorbed exactly, and become heat energy to discharge its power conversion, to reach the ultraviolet purpose of minimizing.Strictly say, can be with the material of ultraviolet reflection ultraviolet light screener, to ultraviolet ray have strong selective absorb and can carry out power conversion and the material of transit dose that reduces it ultra-violet absorber.But in fact shielding exists simultaneously with absorption, and they have improved the ultraviolet protection function of fiber and textiles from different approach.
Kinds of fibers is different, and its ultraviolet ray transmissivity is also different.The natural fabrics such as cotton, real silk are low to ultraviolet absorbability, thereby antiultraviolet line poor performance, and wherein COTTON FABRIC is the most meable fabric of ultraviolet ray.
Uvioresistant finishing agent commonly used divides inorganic and organic two large classes at present.Uvioresistant finishing agent commonly used is metal, metal oxide and its esters, for example TiO mostly
2, ZnO, Al
2O
3, kaolin, talcum powder, carbon black, iron oxide, lead monoxide and CaCO
3Deng.Inorganic uvioresistant finishing agent and fabric fibre binding ability are relatively poor.Organic uvioresistant finishing agent mainly is to absorb ultraviolet ray and carry out power conversion, ultraviolet ray is become low-energy heat energy or the shorter electromagnetic wave of wavelength, thereby reach the purpose of ultraviolet radiation preventing.Generally have conjugated structure or hydrogen bond.Such uvioresistant finishing agent has certain toxicity.
Develop a kind of ultraviolet prevention fiber that is non-toxic and safe, has an excellent durability again and become important research topic.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of production method of ultraviolet prevention fiber, the defects that exists to overcome prior art.
For solving the problems of the technologies described above, the production method of ultraviolet prevention fiber of the present invention comprises the steps:
1) antiultraviolet master batch preparation: with anti-ultraviolet finishing agent and vector resin blending, drying, enter the extruser melt blending and extrude, granulation obtains the antiultraviolet master batch;
2) ultraviolet prevention fiber production: after antiultraviolet master batch and fibre section blend, after spinning, coiling, stretching, form ultraviolet prevention fiber.
Described anti-ultraviolet finishing agent is comprised of the component of following weight portion:
25～35 parts in zinc oxide;
5～8 parts in zeolite;
2-(2 '-hydroxyl-5 '-aminomethyl phenyl) 20～23 parts of benzotriazole;
15～25 parts of two (3,5-di-t-butyl-4-hydroxyl) benzylphosphonic acid mono ethyl esters;
0.5～0.7 part of Sodium Polyacrylate dispersant.
Anti-ultraviolet finishing agent content is 5～20wt% in the antiultraviolet master batch.
Antiultraviolet master batch and fibre section 1: 10 in mass ratio～20 mixes.
The ultraviolet prevention fiber production technology is identical with similar conventional fibre production technology.For example, the production of antiultraviolet terylene, gram adds a certain proportion of antiultraviolet polyester master particle in the polyester slice, fully mixes in rotary drum dryer, drying, to reach homodisperse purpose.Process conditions and process are pressed the drying process of polyester slice and are implemented.During spinning, spinning machine winding speed 3200m/min, draw false twist texturing machine draft speed 150～800m/min; 282～288 ℃ of spinning temperatures.
Anti-ultraviolet finishing agent can adopt general mixed method, preferably adopts following method preparation:
With 2-(2 '-hydroxyl-5 '-aminomethyl phenyl) benzotriazole, two (3,5-di-t-butyl-4-hydroxyl) benzylphosphonic acid mono ethyl ester and zeolite mix, then slowly add simultaneously zinc oxide and Sodium Polyacrylate dispersant, feed intake in 1～2 hour complete, continue to mix 20～30 minutes.
As a kind of preferred version, preferred average grain diameter 300～1500 nanometers of described zinc oxide;
Described Sodium Polyacrylate dispersant preferred viscosities 300～350mPas.
The present invention organically combines inorganic and organic anti-ultraviolet finishing agent, and selected specific auxiliary agent is composited, and has the advantage of two kinds of anti-ultraviolet finishing agents concurrently, can with the fibr tissue strong bonded, durability is strong, and fabric is had good anti-ultraviolet effect, non-toxic and safe.
