Description
Technical field
The present invention relates to a kind of method preparing coloured multifunctional woolen fabric, belong to functions of textile fabrics finishing technique field.
Background technology
At present, adopt colloidal sol to carry out functionalization to textiles to arrange and mainly realized by following approach: first prepare Nano sol by sol-gel process, then its gelation is made, then by gel drying with remove the inside organic principle, under the high temperature of 300 ~ 800 DEG C, ultra-fine nano-powder is made in roasting again, and the functional modification finally nano-powder being applied to textiles arranges.
Wool spinning fabric is the important fabric with making high-grade business shirt, and wool spinning fabric good hand touch is comfortable and easy to wear, dark liking by consumers in general.But, at present environment-friendly function arrangement is carried out to it, thus meet people, to it, there is polyfunctional demand, also there is a certain distance.
Summary of the invention
The object of this invention is to provide one can give wool spinning fabric color simultaneously, improve fastness to rubbing, color fastness to washing, and the preparation method with the wool spinning fabric of good antistatic behaviour, fire resistance and gas permeability.
The technical scheme realizing the object of the invention is to provide a kind of method preparing coloured multifunctional woolen 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 leachings two in coloured Nano silica sol rolled, pressure is 1 ~ 3kg/cm
2, pick-up is 70 ~ 90%, preliminary drying under the temperature conditions of 60 ~ 80 DEG C, then under the temperature conditions of 100 ~ 160 DEG C, bake 1 ~ 4 minute, through washing, after naturally drying, obtains a kind of coloured multifunctional woolen fabric.
Coloured Nano silica sol of the present invention adopts sol-gel process preparation, step comprises: by even to ethyl orthosilicate, ethanol and mixed in hydrochloric acid, slowly drip the iron ion aqueous solution under agitation, 60 ~ 80 DEG C are warming up to again after dropwising, stir 1 ~ 2 hour, namely obtain a kind of coloured Nano silica sol.
Principle of the present invention is: ethyl orthosilicate first in alcohol solvent, poly-condensation and hydrolysis occurs, and generates sol particles; Mix iron ion, form the coloured Nano silica sol of tool.Be adsorbed onto fully on fabric by this colloidal sol by the mode of padding, bake in process in follow-up, colloidal sol changes xerogel into and at the surface filming of fabric, and this film can firmly cover at web surface, to realize arranging the functional modification of fabric.
Compared with prior art, advantage of the present invention is: select ethyl orthosilicate to be the sol solutions of precursor power containing iron ion, sol solutions is coloured, nontoxic, and sol particles is uniformly dispersed and stablizes; Adopt and roll the method for sorting curing this applicable textiles, only need carry out the heat treatment of 100 ~ 160 DEG C to fabric, can be formed at fabric face and adsorb firmly gel film.Fabric after arrangement not only has the color compared with high color fastness, have also obtained excellent antistatic behaviour, anti-flammability and gas permeability simultaneously.

See accompanying drawing 3, it is the surperficial power spectrum comparison diagram of silica sol modified rear wool spinning fabric prepared by the present embodiment and unmodified fabric, and in figure, a figure is unfinished fabric, and b figure is the fabric after silica sol modified process.As can be seen from b figure in Fig. 3, after arranging, significantly increase Si element and Fe element two peaks, and a schemes the peak of not these two elements in unfinished fabric, the Ludox again demonstrating coated iron ion has respectively been organized on wool spinning fabric.
Fabric after arranging 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 Part I of textiles antistatic property: electrostatic pressure and half-life ".
Table 1 lists the color fastness to washing and the fastness to rubbing that arrange rear wool spinning fabric by the embodiment of the present invention 1 ~ 3 technical scheme.
Table 1
| Fabric sample | Staining | Variable color | Unlubricated friction | Wet and rub |
| Embodiment 1 processes | 4 | 3～4 | 4 | 3～4 |
| 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 arrangement has good dry fastness and fastness to wet rubbing, variable color fastness and staining fastness general.After explanation coloured silicasol arranges, define film on the surface of fabric, anchor at web surface, make it have good color fastness to washing and fastness to rubbing.
Table 2 is permeability contrasts of wool spinning fabric before and after arranging.
Table 2
As can be seen from Table 2, the gas permeability that arrangement is expected below obviously increases.This is mixing due to iron ion, makes Ludox form the film of loose structure at web surface, thus the gas permeability of fabric is improved.
Table 3 is antistatic behaviour contrasts of wool spinning fabric before and after arranging.
Table 3
| Fabric sample | Half-life/s | Electrostatic pressure/kv | Partly decline voltage/kv |
| Untreated | 6.57 | 1.76 | 0.83 |
| Embodiment 1 processes | 0 | 0.08 | 0.04 |
| Embodiment 2 processes | 0 | 0.06 | 0.03 |
| Embodiment 3 processes | 0 | 0.04 | 0.01 |
As can be seen from Table 3, the antistatic behaviour that arrangement is expected below is significantly improved than unmodified fabric.This is because employing sol-gel technique, to colloidal sol carry out physics or and chemical modification after, can be used for the dyeing of fabric, and fabric several functions can be given.The surface that arrangement is expected below defines the film of complicated tridimensional network, imparts the antistatic behaviour that fabric is good.
Table 4 is limited oxygen index contrasts of wool spinning fabric before and after arranging.
Table 4
| Fabric sample | LOI/% |
| 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, be all improved through modified fabric limited oxygen index, this index is higher, gets over difficult to burn under normality.Illustrate that this method of modifying can give fabric certain fire resistance.
The present invention adopts directly pads coloured Nano silica sol of preparation on wool spinning fabric, again fabric is baked, in the process baked, coloured Nano silica sol can form the strong porous three-dimensional network thin-film of adhesion on fabric, fabric is while being given color by colloidal sol, also possess good fastness to rubbing and color fastness to washing, good antistatic behaviour, anti-flammability and gas permeability.The present invention's coloured silicasol of iron-doped iron that adopted sol-gel process to prepare, to dye to wool spinning fabric with it and functionalization arranges, and meets the demand of people to environment-friendly function wool spinning fabric.
