Description
Technical field
The present invention relates to a kind of method for preparing coloured Multifunctional fur textile fabric, belong to functions of textile fabrics finishing technique field.
Background technology
At present, adopting colloidal sol that textiles is carried out the functionalization arrangement mainly realizes by following approach: prepare Nano sol with sol-gel process first, then make its gelation, then with the organic principle of gel drying with the removal the inside, ultra-fine nano-powder is made in roasting under 300～800 ℃ high temperature again, at last nano-powder is applied to the functional modification arrangement of textiles.
Wool spinning fabric is with the important fabric of making high-grade business shirt, and the wool spinning fabric good hand touch is comfortable and easy to wear, deeply is subjected to liking of consumers in general.Yet, at present it is carried out the environment-friendly function arrangement, thereby satisfy people it is had polyfunctional demand, also exist a certain distance.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can give simultaneously the wool spinning fabric color, improve fastness to rubbing, color fastness to washing, and have the preparation method of the wool spinning fabric of good antistatic behaviour, fire resistance and gas permeability.
The technical scheme that realizes the object of the invention provides a kind of method for preparing coloured Multifunctional fur textile fabric, comprises the steps:
1, in molar ratio, ethanol: ethyl orthosilicate is 3～13:1, water: ethyl orthosilicate is 2～16:1, FeCl
36H
2O: ethyl orthosilicate is 0.1～0.5:1, prepares coloured Nano silica sol;
2, wool spinning fabric two is soaked two and rolls in coloured Nano silica sol, pressure is 1～3kg/cm
2, pick-up is 70～90%, preliminary drying under 60～80 ℃ temperature conditions bakes 1～4 minute again under 100～160 ℃ temperature conditions, through washing, after naturally drying, obtain a kind of coloured Multifunctional fur textile fabric.
Coloured Nano silica sol of the present invention adopts the sol-gel process preparation, step comprises: ethyl orthosilicate, ethanol and mixed in hydrochloric acid is even, under stirring condition, slowly drip the iron ion aqueous solution, be warming up to again 60～80 ℃ after dropwising, stirred 1～2 hour, and namely obtained a kind of coloured Nano silica sol.
Principle of the present invention is: hydrolysis and polycondensation reaction occur first in ethyl orthosilicate in alcohol solvent, generate sol particles; Mix iron ion, form the coloured Nano silica sol of tool.By the mode of padding this colloidal sol is adsorbed onto on the fabric fully, follow-up baking in the process, colloidal sol changes xerogel into and at the surface filming of fabric, this film can firmly cover on the fabric surface, to realize the functional modification arrangement to fabric.
Compared with prior art, advantage of the present invention is: selecting ethyl orthosilicate is that presoma has prepared the sol solutions that contains iron ion, and sol solutions is coloured, nontoxic, and sol particles is uniformly dispersed and is stable; The method for sorting that cures this suitable textiles is rolled in employing, only needs fabric is carried out 100～160 ℃ heat treatment, can form at fabric face and adsorb firmly gel film.Fabric after the arrangement not only has the color than high color fastness, has also obtained simultaneously good antistatic behaviour, anti-flammability and gas permeability.

Referring to accompanying drawing 3, it is the silica sol modified rear wool spinning fabric of the present embodiment preparation and the surperficial power spectrum comparison diagram of unmodified fabric, and among the figure, a figure is unfinished fabric, and b figure is the fabric after the silica sol modified processing.Can be found out by b figure among Fig. 3, after arrangement, obviously increase Si element and two peaks of Fe element, and a schemes in the unfinished fabric the not peak of these two elements, proving again coat respectively iron ion Ludox be organized on the wool spinning fabric.
Fabric after arrangement is tested with reference to following standard:
1, color fastness to washing is according to GB/T3921-2008 " textile color stability experiment fastness to soaping " standard testing;
2, fastness to rubbing is according to GB/T3920-2008 " textile color stability experiment colour fastness to rubbing " standard testing;
3, gas permeability is tested according to GB/T5453-1997 " mensuration of textile fabric gas permeability ";
4, antistatic property is tested according to GB/T 12703.1-2008 " the evaluation first of textiles antistatic property: electrostatic pressure and half-life ".
Table 1 has been listed color fastness to washing and the fastness to rubbing by wool spinning fabric after the arrangement of the embodiment of the invention 1～3 technical scheme.
Table 1

| Embodiment 2 processes | 4 | 3～4 | 4 | 3～4 |
| Embodiment 3 processes | 4～5 | 4 | 4～5 | 4 |
As shown in Table 1, the fabric after the arrangement has preferably dry fastness and fastness to wet rubbing, and variable color fastness and staining fastness are general.Explanation has formed film on the surface of fabric after putting in order with coloured silicasol, anchors at the fabric surface, makes it have good color fastness to washing and fastness to rubbing.
Table 2 is permeability contrasts of wool spinning fabric before and after the arrangement.
Table 2
As can be seen from Table 2, the gas permeability of fabric obviously increases after the arrangement.This is because mixing of iron ion makes Ludox form the film of loose structure on the fabric surface, thereby the gas permeability of fabric is improved.
Table 3 is antistatic behaviour contrasts of wool spinning fabric before and after the arrangement.

0 | 0.06 | 0.03 |
| Embodiment 3 |
0 | 0.04 | 0.01 |
As can be seen from Table 3, the antistatic behaviour of fabric is significantly improved than unmodified fabric after the arrangement.This is because adopt sol-gel technique, to colloidal sol carry out physics or and chemical modification after, can be used for the dyeing of fabric, and can give the fabric several functions.The surface of fabric has formed the film of complicated tridimensional network after the arrangement, has given fabric good antistatic behaviour.
Table 4 is limited oxygen index contrasts of wool spinning fabric before and after the arrangement.
Table 4
| The fabric sample | LOI/% |
| Be untreated | 25.2 |
| Embodiment 1 processes | 27.2 |
| Embodiment 2 processes | 26.8 |
| Embodiment 3 processes | 28.5 |
As can be seen from Table 4, the fabric limited oxygen index after modification all is improved, and this index is higher, gets over difficult to burn under the normality.Illustrate that this method of modifying can give fabric certain fire resistance.
The present invention adopts coloured Nano silica sol that will prepare directly to pad on the wool spinning fabric, again fabric is baked, coloured Nano silica sol can form the strong porous three-dimensional network thin-film of adhesion on fabric in the process that bakes, fabric is when being given color by colloidal sol, also possessed preferably fastness to rubbing and color fastness to washing, good antistatic behaviour, anti-flammability and gas permeability.The present invention adopts sol-gel process to prepare the coloured silicasol of iron-doped iron, wool spinning fabric is dyeed and the functionalization arrangement with it, has satisfied the demand of people to the environment-friendly function wool spinning fabric.
