Description
Technical field：
The present invention belongs to textile industry printing technology field, the environmentally protective rare-earths dyeing side of a kind of low energy used
Method.
Background technology：
In back to nature, focus on environmental protection, the today for the 19 big new era for advocating the pursuit personalization of green and low energy,
The tint applications of natural value object dyestuff have long history, but most of natural plant dyes are low to the affinity of textile fabric
Under, it is necessary to it can just be anchored on fiber by mordant, complete the dyeing to textile fabric.And in traditional mordant dyeing technique, it commonly uses
Mordant be mostly heavy metal ion copper, iron, chromium, aluminium etc..But as synthetic dyestuffs middle part graded kind is disabled and is spun
Heavy metal ion content is restricted in fabric, is made that new mordant is urgently selected to replace traditional heavy metal ion, is become mesh
The important urgent task of preceding development textile ecological dyeing processing.With the promotion of dyeing environmental consciousness, high resource consumption,
The traditional dyeing technology of high-energy source consumption is gradually eliminated, and because of the dyed textile object of traditional technology, bright-colored degree is poor；Dyeing
Fastness is low；It is big to contaminate the consumption of auxiliary material amount；Waste strength is high；Chrome content is more；It is serious to directly contribute environmental pollution；Endanger human health.
Traditional dyeing process will pass through long-time high-temperature boiling and dye, this performance to fiber, such as strength, gloss, feel all damage
Wound, consequence is that spinning performance is poor, and row yielding is low, increases energy consumption.
Invention content
To solve the above problems, the present invention is by the way that re chloride is added, has adjusted the parent of dyestuff and fabric fibre
And power, form the process of stable comple.Rare earth element and its compound have higher catalytic activity, rare earth ion and carboxylic
Base, amino have integration, after it enters fibroin fiber polypeptide chain, can change the former spread pattern of fiber molecule, rare earth from
The ligand of ion and the group containing lone pair electrons has very strong complexing centered on son, therefore it can improve fabric
Strongly, improve Dye up-take and color fastness.
Rare-earths dyeing formula：Mixed chlorinated rare earth solution, acid mordant dye, sulfuric acid, acetic acid, arsenic are received, mothproofing agent.It adopts
With matchmaker's method technique after first contaminating, bath raio 1: 15 dyes 100 kilogram/pot of quantity, 0 10 points of overall process time 4 hours.Traditional each
In kind, assorted number scattered dye formula, the rare earth of 0.2-4% is added, subtracts the dye auxiliary material of 2%-8%, measured with acid, subtract anhydrous sodium sulphate entirely
And pull open powder.
Mixed chlorinated rare earth solution additive amount：General more suitable ratio be fiber or dry fabric weight 0.1% to
4%, it is also not quite similar to the additive amount ratio of each kind fabric certainly.Such as：Cashmere, wool product 0.2%-0.35%；Silk
Silk fabric fabric is 2%-4%；Polyamide fibre product is 0.2%-0.4%；Acrylic product is 0.2%-0.35%；Terylene product is 0.2%-
0.3%；The rabbit hair, mat articles 0.2%-0.35%.
Mixed chlorinated rare earth is configured to earth solution by the present invention, in dyeing course, is added in the form of earth solution
Mixed chlorinated rare earth, to enhance its mordant dyeing effect.Specifically preparation method is：By in every liter of dye liquor be added 0.5g-1.0g it is mixed chlorinated
Rare earth calculates, and accurately weighs a certain amount of mixed chlorinated rare earth, and 50% (v/v) hydrochloric acid solution is added, and dissolves by heating, water is added to be made into
Earth solution.
Water resistance through the processed textile of rare earth chloride saline solution improves, i.e., machine washing hand washing weathering color fastness improves
It 0.5-1 grades, does not fade；And with performances such as anti-corrosion, mothproof, acid-proof, fire-retardant, antibacterials.

Specific implementation mode
Rare-earths dyeing dyes 100kg/ pots of quantity, bath raio 1 using matchmaker's method technique after first contaminating, 10 points of overall process time 4 hours
∶15。
Embodiment 1：Dyeing is for goats hair, local hair.By weight, if with 100kg local hairs to be contaminated
Incarnadine, green, then heat 30 DEG C of bath foam, be added sequentially 1. rare earth chloride 0.2-0.8kg, 0.2-0.8kg, 2. acetic acid 2.8kg,
0.9kg, 3. acid mordant dye 2.96kg, 1.48kg, then rises to 90 DEG C of constant temperature bath liquid status by 1 DEG C/min of temperature；It protects
It holds and is added sequentially 4. sulfuric acid 0.24kg, 1kg after ten minutes, continue that 90 DEG C of constant temperature bath foams is kept to go liquid 1/3 plus water drop after forty minutes
Temperature sequentially adds 5. sulfuric acid 0.24kg, 0.4kg, 6. sodium dichromate 1.25kg, 0.76kg to 80 DEG C, 7. mothproofing agent 0.6kg,
0.6kg, then rise to 90 DEG C of constant temperature bath liquid status with 1 DEG C/min and keep contaminating 50 minutes, last clear water, which rinses three times, goes out machine.
Embodiment 2：If being incarnadined with 100kg goats hairs to be contaminated, green, brown, bath foam is heated to 30 DEG C, is added sequentially 1.
Rare earth chloride 0.2-0.8kg, 0.2-0.8kg, 0.2-0.8kg, 2. acetic acid 1.9kg, 0.9kg, 1.9kg, 3. acid mordant dye
Then 2.09kg, 1.71kg, 2.38kg rise to 90 DEG C of constant temperature bath liquid status by 1 DEG C/min of temperature and keep sequentially adding for 10 minutes
Enter 4. sulfuric acid 0.48kg, 1kg, 0.5kg, continues to keep 90 DEG C of constant temperature bath foams that liquid 1/3 plus water is gone to be cooled to 80 DEG C after forty minutes；It is suitable
It is secondary to add 5. sulfuric acid 0.47kg, 1.4kg, 0.45kg, 6. sodium dichromate 1kg, 0.85kg, 1.14kg, 7. mothproofing agent 0.6kg,
0.6kg, 0.6kg, then rise to 90 DEG C of constant temperature bath liquid status with 1 DEG C/min and keep contaminating 50 minutes, last clear water rinses three times
Go out machine.
Rare earth dyeing process is the rare earth resources in order to make full use of my area to account for national reserves 90%, using what cashmere, sheep
Hair, non-woven fabrics carpet, woollen blanket, the rabbit hair, silk, polyamide fibre, acrylic, terylene, silk etc. are dyed.New rare earth dye is opened up in innovation
Color technique and formula increase high added value.The technical energy saving, innovation, low consumption, green, environmental protection are greatly improved and dissipate dye product matter
Amount, the ratio of first-grade products and qualification rate raising+5%-+10% of dyeing product.Conscientiously dyestuff dye-uptake is improved up to 95% or more.It is energy saving
Low consumption contaminates the pollutants such as 100 tons of wools, cashmere and measures ten thousand yuan of 1-1.5 than traditional dyeing saving dye auxiliary material, with acid.
Rare-earths dyeing makes resources advantage become product advantage.Rare-earths dyeing makes dye object pure color, bright in colour, soft light
Bright, good level-dyeing property, machine washing hand washing weathering color fastness improves 0.5-1 grades, and production run, physical index are stablized.Product surcharge
Height increases and dissipates dye designs and varieties, and low energy saving contaminates auxiliary material, reduces dyeing cost, rare-earths dyeing is than traditional dyeing dye-uptake
It improves, dye utilization rate is high and foot water is dense is lower, and dye liquor sewage smelting material amount containing dye significantly reduces, and sewage chrome content is arranged less than country
Index is put, it, can direct emission without sewage disposal.Greatly mitigate and improve mankind's harm and environmental pollution, has apparent
Mixed economy, social benefit.Meet national energy conservation and emission reduction, environmentally protective and sustainable development principle.
