It is the effect of noctilucence.
A kind of preparation method of luminous screen cloth, specially following steps：
First, the preparation of surface modification rare earth light-accumulation fluorescent powder
The method for first using wet ball grinding, the rare earth light-accumulation fluorescent powder of silicate types and silane coupler are mixed
Close, be prepared into pasty slurry, then using the method for wet ball grinding, first cryogrinding high temperature grinding work again is carried out to rare-earth fluorescent
Skill, makes silane coupler surface modified in rare earth light-accumulation fluorescent powder, prepares surface modification rare earth while grinding
Light-accumulation fluorescent powder；
The rare earth light-accumulation fluorescent powder selection trade mark of described silicate types is a kind of or mixing in 207101,207102
Thing；
Described silane coupler is glycidoxy-propyltrimethoxy silane；
The described mass ratio in blending process middle rare earth light-accumulation fluorescent powder and silane coupler is 1: 0.55~0.85；
Packing volume is 60~70% during described wet ball grinding, the grinding zirconium a diameter of 3mm of strain, rotating speed is 1000~
1500 revs/min, cryogrinding temperature control is 15~25 DEG C, and milling time is 30~45 minutes, high temperature grinding temperature control
For 60~70 DEG C, milling time is 45~60 minutes；
Described surface modification rare earth light-accumulation fluorescent powder average grain diameter is 0.5~1.5 micron；
Rare earth light-accumulation fluorescent powder has excellent extinction storage light performance, can especially absorb sunshine and then spontaneous again
Light, is widely used as fluorescence labeling and noctilucence colour development material；Using the method for similar wet grinding, pass through surface modification
Agent prepares the pastes with certain viscosity with rare earth light-accumulation fluorescent powder powder and is ground, and not only increases grinding effect
Rate, while reduce the consumption of coating material, while surface modification effect caused by the introducings of other solvents can also be avoided
The situation of difference, and surface modification is carried out in process of lapping, have to grinding with surface modification and cooperate with stiffening effect, after being beneficial to
Phase fluorescent RE powder it is scattered, while its smaller luminous efficiency of particle diameter is higher；Using silicates rare earth light-accumulation fluorescent powder and
Silane coupler is compounded, because material belongs to siliceous class material, and silane coupler is glimmering to inorganic rare earth storage light in itself
The influence of light powder is small, while also having reached the effect of surface modification, it is to avoid pure organic coating material is to rare earth storage light fluorescence
The influence of powder, reduces the luminous especially storage light efficiency of material；Using the segmented grinding side of first cryogrinding high temperature grinding again
Formula, is ensureing the situation of grinding efficiency, reduction silane coupler volatilizees in process of lapping, it is ensured that the progress of hydrolytic condensation, by
During silane coupler its hydrolytic condensation, heat release is hydrolyzed, and is condensed heat absorption, there could be higher percent hydrolysis at low temperature
Complete hydrolysis is reached, it is to avoid the siloxanes residual of non-complete hydrolysis, while condensation needs heat absorption at high temperature, it is ensured that certain contracting
Temperature is closed, fluorescent powder surface is sufficiently modified；
2nd, the preparation of rare earth storage light section
The surface modification rare earth light-accumulation fluorescent powder and polyester slice with high viscosity that above-mentioned steps one are prepared are using double spiral shells
Bar extruder carries out melt blending granulation, prepares the section of rare earth storage light；
The inherent viscosity of described polyester slice with high viscosity is 0.75~0.80dL/g,
Mass fraction of the rare earth light-accumulation fluorescent powder body in the section of rare earth storage light is 14~21%,
Melt blending melting temperature is 285~290 DEG C；
3rd, the preparation of the visual polyester monofilament of the height of skin-core structure
With the section of rare earth storage light for sandwich layer, using normal polyester section as cortex, using double groups of composite spinning technologies, melted
Melt spinning, through ring wind quenching, oil, first time drawing-off, winding shaping obtains high visual polyester monofilament fibril, through fibril second
Secondary drawing-off obtains high visual polyester monofilament；
Described cortex and the ratio of sandwich layer are 1.0: 0.3~0.5, the inherent viscosity of normal polyester section for 0.67~
0.68dL/g；
Described ring wind quenching temperature is 25~28 DEG C, and the first drawing temperature is 160~180 DEG C, and drafting multiple is 1.8
~2.0 times, winding speed is 1500~2000 ms/min, and second of drawing temperature is 135~145 DEG C, and drafting multiple is 3.0
~3.5 times；
Using the method for core-sheath spinning, using the component with storage light performance as sandwich layer, storage light structure sheaf is protected, it is to avoid
Because extraneous pollution causes the reduction of the luminous efficiency of rare earth storage light fluorescence, while skin-core structure can be dilute with maximally effective reduction
The migration of native storage light fluorescent components, lifts the luminescent lifetime of monofilament；Multiple draft process is used simultaneously, with low power high-temperature once
Drawing-off, makes powder disperse in the core, and low temperature high drafting, the effect with phase separation spinning, reaches that sandwich layer middle rare earth stores
Light powder is dispersed between sandwich layer and cortex, realizes the addition of low-function component and has high performance purpose.
4th, the preparation of luminous screen cloth
It is raw material using high visual polyester monofilament and conventional polyester monofilament, warp knit is carried out through double rib warp loom, it is high visual
Polyester monofilament is after warping, and it is 15~25g to control tension in Warping, and setting warp run-in is 1500~7500mm/ng, and light screen cloth
Mesh figure is surface pentalpha, triangle, one kind in rhombus；
Yarn threading main technique is during its warp knit：
Compared with prior art, the positive effect of the present invention is：
It has excellent storage light performance and luminosity for a kind of luminous screen cloth of the present invention and its application in children's footwear, and
Using the spinning of skin-core structure, it is to avoid in conventional co-blended spinning, cause light in fibre because being uniformly distributed monofilament ray structure
Dimension is internal without effect is penetrated, and luminous efficiency is low；While skin-core structure component, the structure using rare earth storage light fluorescence is sandwich layer, not only
The migration and precipitation of rare earth light-accumulation fluorescent powder body are avoided, it is ensured that illumination effect and service life, while reducing contaminated
May, improving luminous efficiency；Simultaneously when modifying fluorescent powder, using the segmented grinding side of first cryogrinding high temperature grinding again
Formula, is ensureing the situation of grinding efficiency, reduction dressing agent silane coupler volatilizees in process of lapping, it is ensured that silane coupler exists
There could be higher percent hydrolysis to reach complete hydrolysis under low temperature, it is to avoid the siloxanes residual of non-complete hydrolysis, while ensureing high
The lower condensation of temperature needs heat absorption, fluorescent powder surface is sufficiently modified；The visual polyester monofilament of height prepared by the present invention exists
Warp knit screen cloth, is especially with a wide range of applications to the attractive vamp screen cloth field of children.
