Description
Technical field
The present invention relates to field of textiles, the pretreating process before more particularly to a kind of yarn dyeing.
Background technology
With industrial expansion, environmental problem is increasingly severe, and energy-saving and environmental protection, cost-effective technique are increasingly obtained
The favor of the producer.
In field of textiles, yarn is before pulp before being dyed, it is necessary to pre-processed, it is main such as bleaching, it is concise, with
Improve the glossiness of yarn.And conventional pretreatment technique need to use higher temperature (generally 105~110 DEG C) and pretreatment
Dye-uptake is poor afterwards, causes follow-up yarn dyeing step to waste more dyestuff, and higher temperature consumes energy, unnecessary dyestuff
Processing to sewage also brings burden.
At present, to increase the dye-uptake of yarn, some cation-modified methods can be used, although this method can be in dyeing
It is helpful in depth, but the fastness after dyeing, especially dry fastness and fastness to wet rubbing, and do not improve can be reduced
The problem of pre-treatment step high temperature consumes energy.In addition, cation-modified step and remaining pre-treatment step of yarn are in view of technique bar
The difference of part, to avoid the influence to treatment effect, is generally carried out separately, i.e., first carry out it is cation-modified after, dry yarn
Line, then carry out remaining pre-treatment step.The time is so not only wasted, source chemicals, water, energy etc. is also further wasted,
Increase production cost.
The content of the invention
Based on this, it is necessary to which providing one kind can be while carries out a variety of yarn pretreatments, and raising yarn dye-uptake, color are firm
The qualities such as degree, glossiness, and power consumption is few, the pretreating process before the low yarn dyeing of cost.
A kind of pretreating process before yarn dyeing, comprises the following steps:
(1) yarn is taken, chelated dispersants, refining agent, alkali, graft modification agent and water, stirring mixing is added;Wherein, it is described
Graft modification agent is quaternary ammonium salt polymer composite, and consumption is the 2%~5% of the yarn weight;
(2) bleaching agent is added, 70 DEG C~90 DEG C are warming up to, 30min~60min is incubated;
(3) clean, you can.
Pretreating process before the yarn dyeing of the present invention:
First, graft modification technique is added before dyeing:Table is carried out to yarn using the specific graft modification agent
Face handle, in yarn fibers, add colouring functional group, allow yarn can more effectively in follow-up dyeing course with dyestuff
Molecule is combined, reaction, is improved dye-uptake, is reduced the waste of dyestuff, and the color fastness of yarn can be also obviously improved;Meanwhile, because
Preferably to adsorb dyestuff by the yarn after above-mentioned graft modification, so needed for during follow-up yarn dyeing can be reduced
Raw material dosage, such as glauber salt, soda ash, have both saved cost, and environmentally friendly.
Secondly, the pretreatment such as modification and bleaching of yarn is carried out with process:By substantial amounts of experimental exploring, by reasonable
The temperature and time of pretreating process is controlled, being modified to yarn for the graft modification agent used can be promoted, is contaminated in raising
While rate, additionally it is possible to the synchronous bleaching for carrying out yarn, and dye and the effect of bleaching in guarantee, pretreatment institute has been saved again
The time of cost and source chemicals.And compared with traditional handicraft, pretreating process temperature is reduced 15~40 DEG C by the present invention,
Pretreatment can be completed at 70~90 DEG C, energy consumption is reduced.
Again, the alkali and bleaching agent needed for bleaching are added separately to, it is to avoid high concentration directly mixing causes bleaching
The possibility that agent is decomposed, further optimizes the bleaching effect to yarn.
To sum up, the pretreating process before yarn dyeing of the invention, by using specific graft modification agent and combination spy
Fixed pretreating process, can be synchronous that dye and bleaching pretreatment are carried out to yarn under relatively low temperature conditionss, improves yarn
