Abstract
The invention relates to an inverted reflecting optical fiber manufacturing technology and belongs to the technical field of heteromorphous compound fiber spinning. A two-component heteromorphous compound fiber spinning technology is adopted, namely the section of the first fiber component is encircled by more than three cat eye shaped sections which are tangent with one another; the second heteromorphous fiber component is filled in the hollow part encircled by the first component; the first component of the fiber requires higher transparency, and the radius of the semicircle of each cat eye shaped section is in accordance with the relation: the radius of the large semicircle=the radius of the small semicircle/(component-refractive index-1); and the second component has higher reflecting performance. The inverted reflecting silk can be made of common spinning high polymer. Due to reduction of material cost and manufacturing cost of the inverted reflecting silk, the use range of the inverted reflecting material can be expanded greatly; the inverted reflecting silk can be directly used as the inverted reflecting material and formed by tatting, knitting, weaving and the like so that the inverted reflecting silk can be really combined with fabric or adornments; the performance is consistent; and the product exploitation is facilitated.
Description
Technical field
The present invention relates to a kind of fiber, belong to special-shaped complex fiber spining technology field with converse light effect.
Background technology
Converse light is also referred to as regression reflecting, no matter it is meant how the incidence angle of light changes, always the catoptrical direction of illuminated object is pointed to light source.This material belongs to the high-visibility reflectorized material, as contrary reflective membrane, converse smooth fabric etc.Contrary refractive body is the core of converse luminescent material.At present commonly used have two kinds of contrary refractive bodies: the glass microballoon of high index of refraction and microprism are against refractive body.The contrary refractive body of microprism is mainly used in makes reflecting piece, version etc., as bicycle, the extensive reflecting piece that adopts of motorcycle afterbody.A large amount of contrary reflective membranes that use, converse smooth fabric is made with glass microballoon.This glass microballoon particle diameter is little, and out-of-roundness, the transparency all have high requirement, and especially the refractive index requirement is very high, and manufacture difficulty is big, and yield rate is low, and processing cost is very high.In addition, in converse luminescent material, glass microballoon is one of them member, must add reflector layer at privileged site, just has the converse optical property of real meaning.In the manufacturing of converse luminescent material, glass microballoon need adopt plants pearl or mixes attached to the method on the base material with coating, causes big difficulty for the processing of converse luminescent material, and performance and purposes are restricted.
Rainbow is to be formed by the inner surface reverberation chromatic dispersion of a large amount of droplets behind the rain.This mechanism is successfully discussed by geometric optical theory at first by the flute card, is called flute card line so will produce this bundle light of rainbow.Flute card line is the catoptrical a kind of unique phenomenon of transparent ball inner surface, and its maximum characteristics are that luminous intensity height, directionality are good, and when refractive index equaled 2, flute card line pointed to light source, and converse photosensitiveness is promptly arranged.Just be based on these characteristics, extensively adopting the clear glass microballon of high index of refraction in the converse luminescent material as refractive body.The transparent column fiber during perpendicular to fiber axis incident, also has the condition that produces Descartes's line at light, and this gives and makes converse fiber optics condition is provided.But spinning at present reaches 2 with the refractive index of high polymer and is difficult to accomplish, and this makes and utilizes flute card line principle to make converse fiber optics to be difficult to realization.
Summary of the invention
The contrary refractive body of opal shape is to utilize two sizes to have the transparent hemisphere of certain relation to make up to realize converse smooth function.Hemisphere before and after two hemispheres divide, the centre of sphere overlaps, and preceding hemisphere is little, and rear quarter is big, and the rear quarter sphere is coated with reflector layer, and light hemisphere is in the past injected.If front and back hemisphere refractive index is identical, when the large and small hemispheres radius satisfies relation: the more than half radius of a ball=smaller part radius of a ball/(two hemispheres refractive index-1), the reverberation of opal refractive body has retro-reflective properties.In essence, refractive index equals the special case that 2 o'clock transparent ball is the contrary refractive body of opal shape.Both differences are that the refractive index of the contrary refractive body of opal shape can be less than 2.Technical scheme of the present invention is utilized this principle just.Adopt bi-component special-shaped complex fiber spining technology spinning fibre, promptly the cross sectional shape of special-shaped complex fiber component one is by three tangent surrounding of above opal tee section, and component one is surrounded the component two of the hollow space filling special-shaped complex fiber of formation.Require to have higher transparency and the big small semicircle radius of each opal tee section to satisfy relation by the tangent component that surrounds of a plurality of opal tee sections in this special-shaped complex fiber: large semicircle radius=small semicircle radius/(component one refractive index-1); Fill the component two that a plurality of tangent opal tee sections surround the hollow space of formation and require to have higher reflective function.During light irradiation fiber, light converges, reflects at the large semicircle inner surface of opal tee section, produces reflex reflection light.The component two adjacent with opal tee section large semicircle has higher reflective function, transmitted light can be converted into the inner surface reverberation, the wide big reinforcement of reflex reflection that fibre fractionation one opal tee section is formed.
The invention has the beneficial effects as follows: avoided the requirement of spinning, used common spinning to make feasible that converse chevilled silk becomes with high polymer with the high polymer high index of refraction.Make converse chevilled silk with special-shaped composite spinning method, can increase the scope of application of converse luminescent material because of the reduction of material cost and processing cost greatly.Converse chevilled silk is a complete contrary refractive body, need not reprocess, and can directly use as converse luminescent material.Converse chevilled silk has linear character, can adopt tatting, and is knitting, and weaving method such as braiding make its real and fabric or jewelry fusion, and performance is more consistent, is convenient to product development.This reflecting thread also can be used for making all kinds of textile decoration materials except that can manufacturing reflective protection uniforms for worker and sportswear.
Description of drawings
The present invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is a special-shaped complex fiber cross section structure schematic diagram of the present invention.
1. components one among the figure, 2. component two.
The specific embodiment
Adopt special-shaped composite spinning method, the special-shaped complex fiber cross section structure as shown in the figure, in the drawings, component one is selected polyester (PET) for use, component two is selected the polyester that adds aluminium powder or copper powder for use.Component one makes it have higher transparency by control process.Component two makes it have higher reflective function by adding aluminium powder or copper powder.
