Description
Technical field
The present invention relates to a kind of manufacture method of functional fibre, especially a kind of with the poor manufacture method that is converted into the conductive fiber of voltage difference of luminous energy.
Background technology
The common fault of chemical fibre is that hygroscopicity is poor, insulation patience is good, electrostatic phenomenon is serious.Chemical fibre in use static constantly accumulates, and is very unfavorable to person health, and produces danger under Code in Hazardous Special Locations and operating position, can produce electric shock to human body such as higher electrostatic pressure, and cause component wear; Static discharge can cause the accidental explosion of gunpowder and chemicals in addition; The electromagnetic radiation meeting that static discharge produces causes electromagnetic interference to various electronic equipments, information system.In view of the significant damage that static causes, the Japanese labour safety and hygiene regulation of enforcement just required all working clothes must have antistatic property from 1996, and also there is similar regulation in many developed countries.Therefore make as when chemical fibre has the important topic that anti-static function is current chemical fibre area research.
The consumption maximum mainly is polymer/conductive black composite at present, studies show that in order in polymeric matrix, to form conductive network, need to add a large amount of carbon black pellet (weight ratio〉20%), destroyed the rheological characteristic of polymer, the processing and forming and the mechanical property variation that cause material are badly in need of seeking the novel conductive filler with the conductive fiber of preparation high comprehensive performance.
Titanium dioxide can become the titanium dioxide with electric conductivity through after the surface chemical modification, makes like this titanium dioxide not only keep pigment characteristics but also had electric conductivity.Conductive titanate dioxide is as a kind of conducting powder, for its preparation and application, domesticly just has been in the starting stage, but abroad taken much count of, and particularly in Japan, realized industrialization.This mainly is because compare with anti-static material with traditional conduction, the titanium dioxide conducting powder has obvious advantage, particularly along with the develop rapidly of information industry, the demand that antistatic and electromagnetic shielding are coated with increases severely, thereby makes conductive titanate dioxide have wide market prospects.Compare with anti-static material with traditional conduction, the titanium dioxide conducting powder has the following advantages: the volume resistance of conductive titanate dioxide powder only has 1 ~ 10 Ω cm, and therefore a small amount of titanium dioxide conducting powder just can make plastics, coating, fiber etc. have anti-static function; Under many application conditions, product has certain requirement to the color of conductive filler, and the conventional conductive materials such as graphite and metal be because color can have influence on the outward appearance of product deeply inevitably, and the titanium dioxide conducting powder has then remedied this defective because whiteness is high; Compare with existing organic antistatic additive, the titanium dioxide conducting powder has the aging-resistant advantage, not the restriction of climate and environment for use; Surface treated titanium dioxide powder has good dispersiveness, and it can be evenly dispersed in the various materials as antisatic additive, improves antistatic property.
Lanthanide series has the 4f shell of underfill and the characteristic that the 4f electronics is shielded by outer-shell electron, lanthanide series matrix is transplanted in the polymeric matrix, generation has the light accumulation type spinning solution, and the spun fiber of institute is being subjected to the light time to capture the excitation state electronics, stops the luminescent transition that continues after the illumination.The distribution of lanthanide series content of material changes in gradient, so the electron amount that goes out of transition also is corresponding graded throughout, thereby make fiber radially have voltage difference, and then with the poor voltage difference that is converted into of luminous energy, be distributed with a certain proportion of conductive materials in the fiber, possess the required condition of circuit, thereby can prepare the poor conductive fiber that is converted into voltage difference of luminous energy.
How many its auxiliary material mouth chargings of traditional double extruder type spinning machine is to control by the rotating speed of gear, although how much can regulate inlet amount, this amount can only be several definite values, and inlet amount cannot change in the cycle.
In the scientific research, sensor has outstanding status.The development of modern science and technology has entered many frontiers: for example will observe boundless and indistinct universe on macroscopic view, will observe Particle World on the microcosmic, vertically upper will the observation reaches the cosmogony in hundreds thousand of years, and the moment that is short to s reacts.In addition, the various extreme technical research of important function has also appearred in-depth material understanding, developing new forms of energy, new material etc. are had, such as superhigh temperature, ultralow temperature, super-pressure, ultrahigh vacuum, ultrastrong magnetic field, superweak magnetic field etc.Obviously, obtain the information that a large amount of human sense organs can't directly obtain, the sensor that does not adapt is impossible.The obstacle of many scientific researches at first just is that obtaining of object information has difficulties, and the appearance of some new mechanism and highly sensitive detecting sensor, tends to cause the breakthrough in this field.Existing sensor exists service life short, because the problems such as more loaded down with trivial details are changed in the restriction of some sensor application condition.
