Abstract
The invention relates to a preparation method of functional ultraviolet-proof fiber. The preparation method specially comprises the steps of adding of an ultraviolet screening agent, crosslinking, linking and mixing, spinning, stretching, fiber forming, operation of a carding machine, operation of a predrawing frame, fiber predrawing, roving forming, spun yarn forming and spooling in sequence. According to the fiber, molecules of the screening agent and large molecules of the fiber are linked to the fiber through a crosslinking agent, so that ultraviolet light is reflected or can be strongly and selectively absorbed, energy conversion can be carried out, radiation is carried out through heat energy or other harmless low energy, the energy is consumed or released, and the fabric is not discolored after absorbing ultraviolet light, has no simulation to skin, and is safe and nontoxic.
Description
[technical field]
The present invention relates to a kind of preparation method of functional ultraviolet prevention fiber, belong to textile yarn technical field.
[background technology]
Because the halide such as freon are discharged in a large number, being trapped in earth overhead, there is chain chemical reaction in the active chlorine formed by ultraviolet light degradation and ozone, makes ozone layer in air suffer to destroy formation cavity, cause Ultraviolet radiation on ground, thus the skin of people is damaged.In the face of more and more serious environmental problem, people focus on self protection more, and ultraviolet resistant textiles is equally subject to people with other shieldings and pays close attention to.Current fabric uvioresistant effect evaluation method has spectrophotometer method, uitraviolet intensity cumulative method, variable color Fading Spectrophotometic Method and direct-vision method etc., and wherein spectrophotometer method is more excellent; Spectrophotometer can detect the transmittance under each different wave length, is method popular and the most general in the world at present; Direct-vision method due to ultraviolet excessive exposure harmful, should be adopted as suitable less.Current primary evaluation standard both domestic and external has: GB/T18830-2002 of China, and adopt the ultraviolet ray transmissivity of integrating sphere type ultraviolet specrophotometer test fabric, ultraviolet ray transmissivity is less, shows that fabric cutting off ultra-violet ray effect is better; Or utilize the Ji Bu that light-sensitive coloring agent dyes, under being placed on standard ultraviolet source, cover fabric to be measured above, open light source, illumination one timing is asked, then observe the change color situation of photosensitive dyeing base cloth below covering, change color is less, illustrates that fabric to be measured intercepts ultraviolet effect better; Or utilize UV-irradiation to be placed on fabric on uitraviolet intensity accumulation meter, irradiate by preset time, determine and then calculated by the ultraviolet cumulative amount of fabric.; Or use Uvr Protective Fabric to cover skin with the non-Uvr Protective Fabric of identical material respectively, carry out direct paired observation by irradiation ultraviolet radiation.
Current fabric or fiber are very low on antiultraviolet shielding rate, between 30-50%, existing fiber can not effectively shielding of ultraviolet to the radiation injury of human body.
[summary of the invention]
The object of the invention is to: for defect and the deficiency of prior art, the preparation method of a kind of functional ultraviolet prevention fiber providing a kind of rate of ultraviolet shield high, the fiber prepared through this kind of method makes ultraviolet screener performance greatly improve, simultaneously fiber or fabric its absorb nondiscolouring after ultraviolet, non-stimulated to skin, safety non-toxic.
For achieving the above object, the technical solution used in the present invention is:
The preparation method of a kind of functional ultraviolet prevention fiber of the present invention, comprises the following steps:
(1) in the fiber selected, add antiultraviolet hide screen agent;
(2), be cross-linked and link mixing, by crosslinking agent, the macromolecular chain in the molecule of antiultraviolet screening screen agent and fiber be connected on fiber;
(3), enter spinning machine, to be added by spinning machine by the product after drawing-off and be twisted silk;
And become fiber by carrying out drawing-off after stretching after spinning (4);
(5), enter carding machine, the chemical fibre sent here is rolled up the chemical fiber layer supplied by automatic flower feeding machine and carry out shredding and divide comb removal of impurities;
(6), by pre-drawing machine, fiber pre-drawing is made, by drawing-off and the synergy of also closing, fortifying fibre mixed effect;
(7), enter Speed frames, twist slivering by the product after drawing-off by Speed frames;
(8), enter fine spining machine, become yarn by the drawing-off of fine spining machine product;
(9), by the yarn after drawing-off import automatic winder, bobbin winder checks and filters yarn;
(10), enter two-for-one twister, evenly twisted by two-for-one twister;
(11), reeled yarn, and control grammes per square metre by reeling frame.
After adopting said method, beneficial effect of the present invention is:
(1), soft, bulkiness is good, prevented from caking; Have very strong ultraviolet screener performance, its rate of ultraviolet shield generally can reach more than 90%;
(2), by crosslinking agent, the molecule of smoke agent for shielding and the macromolecular chain of fiber are connected on fiber, thus applying one can reflect or have strong selective absorbing ultraviolet, and can power conversion be carried out, with heat energy or other harmless low-energy radiations, thus by energy ezpenditure or release, nondiscolouring after its absorption ultraviolet of fabric, non-stimulated to skin, safety non-toxic.
