Abstract
The invention relates to light storage silk and a production process thereof. The light storage silk is mixture of a polybutylece terephthalate (PBT) slice and fluorescent powder; and the light storage silk comprises 90 to 95 weight percent of PBT slice and 5 to 10 weight percent of the fluorescent powder. The production process comprises the following steps of: pre-crystallizing; extruding; filtering; and spinning and winding to form. A product can continuously emit light for 6 to 8 hours, can be recycled infinitely, is good in handfeel, high in luminescence property, stable in performance, is not influenced by washing; and in the production process, the discharge of three wastes (waste gas, waste water and industrial residues) can be avoided, and pollution-free production is realized.
Description
Technical field
The present invention relates to a kind of Functional Chemical Fibers product and production technology thereof, relate in particular to a kind of chevilled silk and production technology thereof held.
Background technology
Polybutylene terephthalate(is called for short PBT), belong to polyester series, be to be formed by 1.4-pbt butanediol (1.4-Butylene glycol) and terephthalic acid (TPA) (PTA) or terephthalate (DMT) polycondensation, and the oyster white of making via mixing program is translucent to opaque, crystalline thermoplastic polyester's resin.Be referred to as thermoplastic polyester with PET, or saturated polyester, PBT is that oyster white is translucent to opaque, crystalline thermoplastic polyester, have high-fire resistance, toughness, fatigue durability, self-lubricating, low-friction coefficient, weatherability, water absorption rate are low, only be 0.1%, in wet environment, still keep various physical property (comprising electrical property), electrical insulating property, but volume resistance, dielectric loss are large.Heat-resisting water, bases, acids, oils but be subject to halogenated hydrocarbon and corrode, hydrolytic resistance is poor, rapidly crystallization under the low temperature, good forming ability.Shortcoming is that notched Izod impact strength is low, and molding shrinkage is large.Therefore most of glass fibre that adopts strengthens or the inorganic fill modification, its TENSILE STRENGTH, bending strength can be enhanced about more than once, and heat distortion temperature also significantly improves.
Fluorescent material is a kind ofly to cause luminous material under ultraviolet ray, visible radiation and electric field action.20 beginning of the century people find fluorescent material in research electric discharge phenomena process, multiple color is arranged, and are mainly used in weak illumination light source and luminescent material.
There is no at present and add fluorescent material among the PBT product and production method thereof.
Summary of the invention
The present invention for overcome the above problems provide a kind of easy to process, product good heat conduction effect, production cost low hold chevilled silk and production technology thereof.
The technical scheme of product of the present invention is: described to hold chevilled silk be PBT section and the mixture of fluorescent material, and the percentage that described PBT section accounts for the material gross weight is 90%-95%, and the percentage that described fluorescent material accounts for the material gross weight is 5%-10%.
The technical scheme of technique of the present invention is: mainly may further comprise the steps:
1) mixture is pre-crystallized: with the mixture of above-mentioned PBT section with fluorescent material, at first by heated drying air material is carried out hot-working, pre-crystallized temperature is 110 ℃, the heated drying air temperature is 150 ℃, air dew point is-80 ℃, material moisture 35PPM, and be 10 hours drying time;
2) material is carried out the screw rod feeding: will push in the above-mentioned dried material feeding pressure ram by special feeding machine;
3) the above-mentioned material after will pushing filters, by filter the above-mentioned material after entering extruding through melting is filtered, during filtration before pressure be 12MPA, the constant pressure in the filter process is 9MPA, the screen pack of filter device therefor is 30 microns during filtration;
4) spinning: above-mentioned material enters in the filament spinning component after filtering, after the ejection, carries out at last coiling and molding from spinnerets.
The advantage of product of the present invention is:
(1) product of the present invention just can be stored in luminous energy among the fiber absorbing visible light after 5 ~ 30 minutes, under the darker environment of light, and sustainable luminous 6-8 hours and can unlimitedly recycle;
(2) because this luminous fiber is to utilize synthetic technology to make, the fabric of therefore making with it has fundamentally overcome the shortcoming that the product surface luminescent material comes off, hand feel performance is poor, luminescent properties is low that traditional coating is made;
(3) stable performance, be not subjected to the washing affect.
The advantage of technique of the present invention is: the major advantage of technique of the present invention is to discharge without " three wastes " in the course of reaction, has realized cleaning production.
