Abstract
The present invention relates to an ultraviolet fluorescent fibre for textile and a manufacturing method of the ultraviolet fluorescent fibre for textile. In the present invention, ultraviolet fluorescent mother particles are made by using the mixture of europium which is a rare earth element and strontium aluminate as ultraviolet fluorescent materials; then, the ultraviolet fluorescent mother particles are made into sheath core type composite yarns with round cross sections, fluorescent mother particles are formed into core wires, and conventional polyester is formed into sheaths; the composite ratio of the fluorescent mother particles to conventional PET is 50/50 to 30/70, the monofilament fineness of the composite yarns is 2.8 to 6.2D, and the thickness of the sheaths is 2.4 to 6.6 mu m. In the fluorescent composite yarns of the present invention, because the content of rare earth light emitting powder in the filaments is high, the filaments have high degree of glowing, and the intensity of the filaments can meet general weaving requirements, the present invention can be applied to anti-counterfeiting textile marks or noctilucent safe mark fabrics, and can be used for dress products. The present invention has good performance of washability and abrasion resistance.
Description
The present invention relates to a kind of weaving ultraviolet fluorescent fibre and manufacture method thereof.
Up to now, the application of luminescent material on textiles is mainly with COAT PRINTING or dyeing, and the coating processing method.Its shortcoming is a poor durability, rub resistance not, and wash resistant not, purposes is restricted.Existing fluorescent fiber generally adds in the fiber in the chemical fibre manufacture process with fluorescent dye, pigment or luminescent material, Chinese invention patent prospectus (CN1092119A for example, safety fibre in the used anti-forge papers such as a kind of marketable securities application number 93102550.8), certificate, this fiber with mixed with polymers such as fluorescent material (content is 0.3%-6.0%) and polyvinyl alcohol after spinning, the fiber of making like this is generally staple fibre.Produce fluorescent fiber with prior art, luminescent material content can not be too high in the fiber, as not surpassing 6%, produces insoluble difficulty otherwise understand in spinning.But this concentration is not enough to obtain higher aura degree, even and luminescent material concentration be no more than 6%, this fiber also is difficult to make and can be directly used in woven long filament, and the intensity of this fiber and processing characteristics are relatively poor, can not be used as textile raw material.
The object of the invention provides a kind of woven fluorescent fiber that is directly used in, and its processing characteristics is applicable to general fabric manufacture equipment, and its purposes on textiles is wider than luminous paint.
The mixture that the used ultraviolet fluorescent material of the present invention is a kind of rare earth elements europium and strontium aluminate, it can absorb ultraviolet ray, and produces long after-glow light, and the aura color depends on luminescent powder surface bag shoe pigment.For luminescent material can be dispersed in the polyester master particle, cohesion does not take place and influence spinning, at first containing rare earth luminous powder, make the luminescent powder particle diameter reach 0.3-0.8 μ m with the pulverizing of supersonic airstream reducing mechanism.Adopt conventional Granulation Equipments to prepare the ultraviolet fluorescent master batch, used prescription following (weight ratio):
Carrier: PET 100
Contain rare earth ultraviolet fluorescent powder: SrAl: Eu 20-40
Dispersant: Tissuemat E 15-25
Lubricant: calcium stearate 1-3
Antioxidant: 1010 0.1-0.4
Coupling agent: titanate ester 1-3
Above-mentioned batching is after high-speed stirred is mixed, and with twin-screw or single screw pelletizer group extruder grain, processing temperature is 265-300 ℃.Use through vacuum drying conventional PET section then and often press dry dry ultraviolet fluorescent master batch and on the twin-screw spinning equipment, be spun into cross section, garden core-skin type compound silk.Compositely proportional is ultraviolet fluorescent master batch/conventional PET section=50/50-30/70, and wherein the ultraviolet fluorescent master batch forms the core silk, is positioned at garden shape section compound silk central authorities, is similarly the garden tee section, and conventional PET forms the cortex silk.One of the technology of the present invention key is: the ultra-fine grinding of luminescent powder.Test shows that the luminescent powder particle diameter reaches Subnano-class (0.3-0.8 μ m) evenly to be disperseed in polymer melt than general particle diameter (10-50 μ m) luminescent powder is easier, does not influence the fluorescence property of rare earth luminous powder again.Therefore can increase luminescent powder content (percentage by weight reaches as high as 23%) in the ultraviolet fluorescent master batch, and the unlikely silk that influences into.Another key problem in technology of the present invention is: fiber adopts cross section, garden core-skin compound silk structure, the compound silk core is for containing the high concentration rare earth luminescent powder polyester of (being up to 23%), thereby guarantee that fiber has higher aura degree, the compound silk cortex is a normal polyester, it can guarantee that fiber reaches certain intensity, as long as its thickness is suitable, influence not quite gets final product to printing opacity.Therefore, the core/sheath ratio of compound silk of the present invention needs rationally to arrange in pairs or groups and balance according to the different works of fiber applications with core master batch middle rare earth luminescent powder content, to require to determine luminescent powder content in the fluorescence master batch according to fiber aura degree, according to different purposes fibre strength and fiber number are required to determine the core-skin proportion of composing again simultaneously, should satisfy the skin thickness that makes fiber can reach requirement of strength, and reduce the core ratio as far as possible, to reduce the luminescent powder consumption, reduce cost, can not influence the cortex light transmittance again simultaneously.
The embodiment of the invention is as follows:
1. disintegrating process:
Reducing mechanism: JGM-H type airslide disintegrating mill
Working media: compressed air
Feed pressure: 0.2-0.4Mpa
Operating pressure: 0.8-1.0Mpa
Charging particle diameter: 10-50 μ m
Discharging particle diameter: 0.8 μ m
2. master batch preparation:
Prescription (weight ratio)
Carrier: PET 100
Rare earth luminous powder: 20
Dispersant: Tissuemat E 15
Lubricant: calcium stearate 1
Antioxidant: 1,010 0.1
Coupling agent: titanate ester 1
Above-mentioned batching is used the dual-screw pelletizer extruder grain after high-speed stirred.
3. spinning technique:
Drying condition: PET section vacuum drying: 8 hours, 180 ℃ of temperature,
Moisture content≤100ppm
Fluorescence master batch normal pressure drying: 3 hours, 110 ℃ of temperature, moisture content≤0.1%
Spinning temperature: main region temperature: 285-295 ℃ of first screw rod (using) for the cortex silk
Main region temperature: 280-290 ℃ of second screw rod (using) for the core silk
Spin manifold temperature: 285-290 ℃
