Description
Technical field
The present invention relates to textile dyeing and finishing technical field, more particularly to a kind of electrostatic self-assembled biomimetic features that improve add lustre to spinning
The method of review of fabric color durability.
Background technology
The main path for making textile generation color at present is by applying coloring matter (dyestuff or face on the textile
Material) realize, it is the result that coloring matter produces selective absorbing effect to light, is referred to as pigmentary color.And in nature
Blue sky, rainbow, butterfly's wing, peacock feather, shell and all kinds of jewelly jewels etc., are the physical arrangements with particular organization
The effects such as scattering, dispersion, interference or diffraction to light produce color, are referred to as schemochrome.Schemochrome generally has highlighted
Degree, high saturation, iris phenomenon, it is will never fade the advantages that, as long as the Stability Analysis of Structures of material, its color will not cut down.Simulation is certainly
Micro-structural in right boundary, the biomimetic features for being applied to textile add lustre to, and can prepare that (color is with observation with rainbow effect
The change of angle and the effect changed), it is agile such as raw novel ecological textile, it will have boundless market prospects.
Add lustre to the preparation of textile on biomimetic features, the A of Chinese invention patent CN 102991048 of Donghua University's application
Disclose a kind of method that fabric construction color is prepared using electrostatic self-assembled method.The patent proposes to exist using electrostatic self-assembled technology
The laminated film that polymer is formed with inorganic nano colloidal particle is prepared on PET (PET) films and fabric,
The biomimetic features for realizing textile add lustre to.Though the laminated film referred in the patent has preferable stability, not to imitative
The add lustre to color fastness of fabric of raw structure has a detailed description and objective examination's evaluation.
This seminar utilizes electrostatic self-assembled method, passes through the water-soluble of the positively charged polyethyleneimine of alternating impregnating (PEI)
Liquid and negatively charged SiO2Nanoparticle sol liquid, changeable SiO lucuriant in design is successfully prepared on dacron2/PEI
Schemochrome film, pass through the morphosis and optical characteristics of analysed film, it is determined that the chromogenic mechanism of schemochrome film, and establish
The self assembling process model of film, to develop the ecological dye technology of textile, to provide certain theory and practice basic, but
The add lustre to color fastness of textile of this structure also fails to the requirement for reaching commercial Application.
For the textile of pigment colored, investigate its color fastness and typically utilize color fastness metrics evaluation, including antifriction
Wipe color fastness, washing color fastness, colour fasteness to sunlight, colour fastness to perspiration etc., wherein colour fastness to rubbing and water-fastness color
Fastness is to evaluate the important indicator of textile color stability height.The electrostatic self-assembled biomimetic features textile that adds lustre to mainly utilizes nanometer
Electrostatic force between particle and macromolecule forms laminated film in fabric face and makes textile that color be presented, this compound
The structural stability of film itself and directly affect structure with the binding strength of fabric and add lustre to the rub resistance of textile and water-fastness
Color fastness.It can be divided into cationic polymer type color fixing agent, resin type color fixing agent for improving the add lustre to color fixing agent of textile of pigment
With cross-linking reaction type color fixing agent three major types, its mechanism of action is mainly：1) cationic fixing agent closing anionic dye is water-soluble
Property group；2) macromolecular solid toner film forming cladding dyestuff；3) color fixing agent with reactivity is reacted with dyestuff.Above-mentioned principle is all
Worked for dye property, thus be applied to pigment colored textile, be not suitable for structure and add lustre to textile.At present
Rarely have on improve electrostatic self-assembled biomimetic features add lustre to textile color fastness research and report.
Silane coupler is a kind of organo-silicon compound simultaneously containing two kinds of different chemical property groups in the molecule, both
It can be reacted with inorganic matter, and can interacts with organic molecule.It can be carried using this bridge linking effect of silane coupler
Compatibility between high inorganic matter and organic matter, so as to substantially improve the application performance of material.SiO2/ PEI schemochrome films are
A kind of inorganic nano-particle SiO by oppositely charged2The laminated film formed with organic polymer PEI.Work as silane coupler
When acting on the inorganic/organic hybrid films that electrostatic self-assembled forms, one end of its molecule can be with the SiO in film2Nanoparticle
Son reaction forms silicon oxygen bond, and the other end can interact with PEI macromolecules, more firm so as to be internally formed combination in laminated film
Solid inorganic/organic hybrid system, coupling agent can also itself film forming in addition.It is bionical using silane coupler processing electrostatic self-assembled
The structure textile that adds lustre to can effectively improve the structural stability of laminated film and its binding strength with fabric, resistance to so as to improve its
Friction and washing color fastness, the durability of its color finally can be achieved.
