Description
Technical field
The present invention relates to natural dye dying technical field more particularly to a kind of promotion natural dye dying cellulose fibres
The method of dye-uptake.
Background technique
The problems such as natural dye dying cellulose fibre is low in the prevalence of dyestuff dye-uptake, mainly due to natural dye
It is difficult to adsorb and anchor on cellulose fibre.Then, in order to promote dye-uptake of the natural dye on cellulose fibre, can lead to
Cross preceding matchmaker, with the staining technique of matchmaker or rear matchmaker, i.e. introducing metal ion, improve dyestuff dye-uptake and product dyed thereby it is water-fastness
Color fastness.It is mainly to be determined due to its molecular structure that natural dye, which is generally difficult to dye cellulose fibre,.Natural dye is to fibre
The affinity of cellulose fiber is poor, causes it on dyeing course, and dye is less to the amount of dye on fiber on dyestuff, needs to be added
Metal ion is complexed, so that on more dyestuff in dye to fiber, and there is preferable washing color fastness.But it is golden
Belong to the use of ion, such as chromium ion, nickel ion etc. will cause certain environmental pollution.It is, thus, sought for another is green
Staining technique.
In order to promote the dye-uptake of natural dye dying cellulose fibre, then needs in dyeing phase, make natural dye
It is adsorbed on fiber as much as possible, fixation treatment then is carried out to the natural dye of upper dye, it is ensured that in upper dye to fiber
Dyestuff is not got off in subsequent soap washing by washout.It, can in order to make cellulose fibre adsorb natural dye as much as possible
The natural dye solution of compounding high concentration, and be dispersed in the medium of decamethylcyclopentaandoxane (D5), to cellulose fiber
Dimension is dyed.
According to hydrophilic dye aqueous solution the alternate distribution of cellulose fiber peacekeeping decamethylcyclopentaandoxane two greatly
The rule for being conducive to cellulose fibre, in decamethylcyclopentaandoxane dye liquor, dyestuff is distributed in dye with high concentration dye liquor droplet
It in color medium, and constantly runs with dyeing medium, contact cellulose fibre repeatedly and fully, make constantly have list in dye liquor droplet
Molecular dye is captured by cotton fiber and spreads over fiber surface.Since the affinity of dyestuff and water and cellulose fibre is much higher than it
With the affinity of decamethylcyclopentaandoxane, this transfer process is unidirectional, therefore in decamethylcyclopentaandoxane dye liquor
It repeated with the continuous circulation of medium, until all dyestuffs are transferred completely into fiber surface namely dye-uptake can be with
Reach 100%.
After completing natural dye absorption, in order to enable having gone up the dyestuff of dye can anchor on fiber, consolidate
Color processing.Existing laking procedure be will complete fiber on contaminate after, empty dye liquor, reinject containing in color fixing agent aqueous solution into
Row fixation treatment.According to traditional color fixing agent aqueous solution laking procedure and technique, then the natural dye that had previously been adsorbed on fiber
Material can reduce the fixed amount of dyestuff from shifting and being dissolved in color fixing agent aqueous solution on coloured fibre.Therefore, through decamethyl ring
After the dyeing of five siloxanes dye liquors, it should be consolidated using the decamethylcyclopentaandoxane fixation system containing high concentration color fixing agent droplet
Color improves natural dye dying cellulose fiber to reach so that the natural dye being adsorbed on fiber is retained on fiber
The dye-uptake of dimension.

Degree of fixation and dye-uptake promoted it is obvious.After fixation treatment, degree of fixation and dye-uptake the increasing with color fixing temperature of dyestuff
First in the trend risen.When color fixing temperature is 80 DEG C, degree of fixation and dye-uptake reach maximum value, respectively 93.79% He
92.20%, then decline.So optimal color fixing temperature is 80 DEG C.
Influence of 7. color fixing temperature of table to Cacao pigment degree of fixation and dye-uptake
| Color fixing temperature (DEG C) | Non- fixation | 40 | 50 | 60 | 70 | 80 | 90 |
| Degree of fixation (%) | 49.17 | 92.00 | 92.50 | 92.84 | 93.49 | 93.79 | 93.68 |

Embodiment 8:
Decamethylcyclopentaandoxane fixation liquid carries out fixation to dyeing cellulosic fibre.
The surfactant A EO-3 and cosurfactant n-octyl alcohol for respectively taking 5g, are stirred until homogeneous, it is molten to be configured to auxiliary agent
Liquid.The compounding agent solution for taking 2.5g to prepare is added decamethylcyclopentaandoxane solution to 100mL, is stirred until homogeneous, be configured to containing
The decamethylcyclopentaandoxane solution of auxiliary agent.It takes 0.02g (1%o.m.f), 0.04g (2%o.m.f), 0.06g (3%o.m.f),
The color fixing agent of 0.08g (4%o.m.f) and 0.10g (5%o.m.f) are dissolved in 2mL (100%o.m.f) water respectively, are configured to
The fixation solution of high concentration containing different color fixing agent dosages is then separately added into the prepared decamethyl ring five containing auxiliary agent
Siloxane solution is stirred until homogeneous to 40mL, completes the preparation of decamethylcyclopentaandoxane fixation liquid.
It dyes, contaminates under optimum condition of the Cacao pigment dye liquor to cotton fiber dyeing of decamethylcyclopentaandoxane
Product dyed thereby, washing, drying are taken out after color, and surveys the K/S value of product dyed thereby, are denoted as (K/S) 0.
The product dyed thereby for taking 2g is immersed in 40mL (bath raio 1:20) decamethylcyclopentaandoxane fixation liquid of preparation, in 80
Fixation 30min at DEG C then takes out, washes, dries, soaping washes away loose colour, and surveys the K/S value of product dyed thereby, is denoted as (K/S) 1.
Foundation degree of fixation formula F %=[(K/S) 1/ (K/S) 0] * 100%, dye-uptake formula T%=E%*F%*100,
The degree of fixation and dye-uptake for calculating dyestuff, are listed in table 8.Without the product dyed thereby of fixation treatment after dyeing, degree of fixation and upper
Dye rate is respectively that 49.17% and 48.33% far below the degree of fixation and dye-uptake of fixation treatment show dyestuff after fixation treatment
Degree of fixation and dye-uptake promoted it is obvious.After fixation treatment, the degree of fixation and dye-uptake of dyestuff with color fixing agent dosage increasing
The trend that Gao Xiancheng rises.When color fixing agent dosage is 0.08g, i.e. 4%o.m.f, degree of fixation and dye-uptake reach maximum value, point
Not Wei 94.75% and 93.14, then keep stablize.So optimal color fixing agent dosage is 0.08g, i.e. 4%o.m.f.
Influence of the 8. color fixing agent dosage of table to Cacao pigment degree of fixation and dye-uptake
Therefore, the optimum condition that decamethylcyclopentaandoxane fixation liquid carries out fixation to dyeing processes is water content 10%
O.m.f, fixation time 30min, 80 DEG C of color fixing temperature, color fixing agent dosage 4%o.m.f.
So being contaminated under conditions of the Cacao pigment dye liquor dyeing processes of optimal decamethylcyclopentaandoxane
Color and fixation, cocoa are carried out under conditions of the color fixing agent fixation liquid fixation dyeing processes of optimal decamethylcyclopentaandoxane
The dye-uptake of shell pigment dyeing processes can reach maximum value, be 93.14%.
The above shows and describes the basic principle, main features and advantages of the invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
