Description
Technical field
Present invention relates particularly to the colouring method of a kind of luminescence generated by light fiber.
Background technology
Luminescence generated by light fiber is a kind of with spinning materials such as terylene, chinlon or polypropylene as base material, more than interpolation rare earth length
Brightness luminescent material and function additive, through the photic light accumulation type luminescent fibre that special spinning technique is made.This fiber only need to absorb appoints
What visible ray 10 minutes, gets final product continuous illumination more than ten hours, and unlimited recycling.It is this fiber green, environmental protection, energy-conservation,
Can be widely applied to the necks such as rescue, night work, fire-fighting emergent, transportation, building decoration, aviation and navigation and dress and personal adornment
Territory.
In recent years, develop multiple rare earth luminous active material both at home and abroad, owing to having original intensity height, persistence
The advantages such as long, "dead" harm are accepted, and luminescent material sends the emission spectrum that peak value is 450～580nm, can be in
The existing color such as blue, bluish-green, green, greenish-yellow, the most yellow long-persistence luminous.But the expansion of the application along with luminescent fibre, above-mentioned face
Color limitednumber, can not meet far away luminescent fibre when being used in combination with other fibrous materials, the problem of color matching.Therefore,
Being badly in need of developing the luminescent fibre that various colors is colorful, the best way is to make luminescent fibre be similar to common textile fabric one
Sample, can realize the variation of color by dyeing.
The luminescent fibre commercially produced at present is mainly rare earth aluminate luminescent fibre, and this fibrid has good length
Afterglow property, chemical property is more stable, but shortcoming is it is also obvious that poor water resistance and glow color are more single.Because of luminescent material
In containing more alkaline earth oxide, in water, easily hydrolysis, in strong basicity, easily rises in acid medium and neutralizes reaction, send out
Luminescent material is destroyed.This makes luminescent fibre after traditional dyeing process processes, and brightness is greatly reduced, and strongly limit luminous fine
Tie up the popularization and application of this excellent functional material.
In order to improve the serviceability of luminescent fibre, luminescent material need to be carried out resistant to hydrolysis process, as use Surface coating,
The technology such as surface modification improve the water resistance of luminescent material, but these processing methods are to solving the hydrolytic resistance of luminescent material not
Being very thorough, use conventional colouring method dyeing luminescent fibre, the luminescent material in fiber still can hydrolyze, and dyeing
Auxiliary agent can destroy the performance of luminescent material, thus after dyeing, the luminescent fibre brightness range of decrease is the most obvious.
