Abstract
The invention relates to a method for producing a polarizing film having local polarization effect. The PVA undergones the processes of washing, swelling, stretching, dying crosslinking, stretching again, washing and stoving. The method is characterized in that: the liquid feed control system automatically controls the dying bumps (4) to dye. A device for producing the polarizing film having the local polarization effect has a completely transparent lens and does not polarize light. Only the exterior viewing position of human eye pupils on the middle upper part of the lens has polarized light discoloration effect in small areas. A polarizer is combined with a liquid crystal light valve to realize depth change of colors in the process of electronic control so as to achieve the effects of making drivers clearly see pavements during driving at night, shielding highlight and reducing dazzling.
Description
Technical field
The present invention relates to light polarizing film and make the field, especially about a kind of device and working method with polarization film of local polarization effect.This part polarization type light polarizing film is exclusively used in the eyeglass of the shading eyeglasses that prevents when meeting at night to dazzle the eyes and makes.
Background technology
The eyeglass of polaroid glasses such as commercially available polarized sunglasses, polarisation fishing mirror, polarisation driver mirror all is to use the consistent polaroid manufacturing of the whole degree of polarization of eyeglass; The polarizing film that this polarized lenses intermediate course uses is evenly to contaminate absorption two-phase look property iodine or dyestuff is made through conventional stretching dyeing at whole PVA film surface; The integral light-transmitting degree is between 25%～45%; Be cut into Sunglasses lenses sun clips on the folder behind the protective seam; Utilize the polarisation effect, block reflected light strong under the sunlight on daytime and have good result of use.But at night; Because polarized lenses is the degree of polarization of uniformity on the whole; Transmittance is the highest to be no more than 45%; The light polarizing film eyeglass that uses this technology to make reaches 75% pressure standard even adopt the reduction degree of polarization also can't make transmittance meet national driver penetrability at night on the whole, so can't well use at night with the method that improves penetrability.Adopt local polarization type polarized light film can solve above-mentioned limitation; It is the eyeglass whole clearing; Polarisation not, the position of only outside the human eye pupil of eyeglass middle and upper part, looking has the polarisation discoloration effect of small size, but up to now; Do not have the appearance and the sale of this series products on the market, do not found the production technology and relevant patent documentation and report of manufacturing local polarization type polarized light film yet.
Summary of the invention
In order to obtain having the light polarizing film of above-mentioned local polarization effect; The object of the present invention is to provide a kind of production to have the method for the light polarizing film of local polarization effect; Be in the dyeing of producing polarized light film; Do not continue to use the whole staining trough that immerses of traditional raw material film and carry out dyeing way, taked the raw material film in the drawing process is carried out the method for the local dyeing of drum-type multiple spot stepping dropping liquid, the polaring film color with local polarization effect is achieved.
Another object of the present invention provides makes above-mentioned device with polarized light film of local polarization effect.
Technical scheme of the present invention realizes in the following manner: a kind of working method with light polarizing film of local polarization effect is characterized in that: described dyeing is realized by following steps:
1), small size dyeing: guide to when moving forward in the dyeing apparatus internal pore by rubber roll through the stretched PVA film of swelling drill traverse bubble; When the dyeing salient point of going up the dyeing cylinder that rotates goes downwards to the mutual upright position of dyeing cylinder down; Under the pressure effect of the cylinder that dyes up and down; The iodine property dyeing liquor of last dyeing cylinder internal memory is contaminated on PVA film surface, has formed the polarized regions of small size;
2), uninterrupted dyeing: on the cylinder rotation of dyeing whenever turn left 90 °; The liquid control system that adds in the dyeing apparatus just replenishes an iodine property dyeing liquor for the corresponding dyeing salient point of going up the dyeing cylinder; Constantly repeat above process, realized having the uninterrupted dyeing production of the light polarizing film of local polarization effect.
Describedly adding the top that liquid control system is located at the dyeing cylinder, is the automatic liquid supply system of photoelectricity or magnetoelectricity control, gives dyeing salient point complementary stain liquid with drum-type multiple spot stepping dropping liquid mode.
A kind of production has the device of local polarization effect light polarizing film; Comprise the PVA film, down dye cylinder, on dye cylinder, dyeing salient point, automatically controlled liquid droping head, surge drum, dyeing liquor, filling opening and add liquid control system; Last dyeing cylinder is located at down the top of dyeing cylinder; But the relative motion of upper and lower dyeing cylinder, described top of going up the dyeing cylinder is provided with surge drum, and the top of surge drum has filling opening; The bottom is connected with and adds liquid control system; The outer wall of last dyeing cylinder is every to be provided with a dyeing salient point at a distance from 90 ° on circumference, in radial array the dyeing salient point of a plurality of parallel interval is arranged, and it is characterized in that: the described liquid control system that adds is controlled the dyeing salient point automatically and is dyeed.
Described add liquid control system by the induction control head, add fluid controller and automatically controlled liquid droping head is formed.
The described dyeing cylinder of going up uses stainless steel to make, and the dyeing salient point uses high-density sponge body material.
The described cylinder of dyeing down uses whippy rubber or plastic material.
The present invention; The eyeglass whole clearing; Polarisation not, the position of only outside the human eye pupil of eyeglass middle and upper part, looking has the polarisation discoloration effect of small size, and this polaroid and liquid crystal light valve combination back have been realized in automatically controlled process that the depth of color changes so as to reaching and have been seen the road surface when making driver's driving at night clearly; Block high light, alleviate the effect of dazzling the eyes.
