Abstract
The present invention relates to a dyeing process of viscose cheese. Said dyeing process includes the following several steps successively: washing before dyeing, dyeing and circularly adding salt, washing, adding acid to make neutralization, washing by using hot water, soaping, washing by using hot water, washing, dye-fixing, mellowing, dewatering and drying.
Description
Technical field
The present invention relates to a kind of dyeing of viscose cheese, belong to the staining technique field of textile fiber material.
Background technology
Viscose is to be raw material with the natural fabric, form through certain chemical process manufacturing, so the basic composition material and the cotton fiber of viscose is similar, all belong to cellulose.
At present, the technological process that industry adopts the dyeing of viscose cheese had two (roads) to dye preceding water-washing step before staining procedure, and have the high temperature pre-treatment step before the water-washing step before two is dyed as shown in Figure 5; Be divided in the staining procedure interim normal temperature once, secondary, three times be with the salt link.
Above-mentioned high temperature pre-treatment step is to adopt the pre-treatment be similar to when dying cotton dark kind, adds soda ash, scouring agent and chelated dispersants in order to further removal impurity, uses to eliminate reducing substances REACTIVE DYES is impacted.The addition of scouring agent is that the addition of 2g/L, soda ash is that the addition of 2g/L, chelated dispersants is 0.5g/L, and bath raio is about 1: 8, and temperature is that 90-100 ℃, time are 20-30min.Adopt the high temperature pre-treatment step to be based on: viscose has adopted CS in spinning is produced
2Carry out yellow and handle,, cause fiber in view of desulfurized effect shortcoming (owing thorough) and have certain reducibility, cause the look of REACTIVE DYES to wither, problems such as look flower, cylinder difference though passed through desulfurization.Therefore as if the high temperature pre-treatment has certain positive effect, but have the following deficiency of attending to one thing and lose sight of another.That is: owing to be subjected to the influence of traditional custom thinking, think that carrying out the high temperature pre-treatment before dyeing is absolutely necessary, yet but ignored viscose and in spinning process, passed through alkali treatment and bleaching, natural impurity is removed substantially, and has whiteness preferably, residual impurity such as sulphur do not need to handle by aforesaid traditional approach, cause the dye process of whole viscose cheese tediously long just because of the existence of this high temperature pre-treatment step, energy consumption increases, water resource waste big (need two roads and dye preceding water-washing step), quantity of wastewater effluent is many, thereby constitutes serious restraining factors for the reduction of entreprise cost.Therefore, the high temperature pre-treatment step is a kind of ceremony that there is no essential meaning that is caused by technology prejudice or the step that claims formality.
The normal temperature that staining procedure (seeing Fig. 5 for details) before more particularly the dying behind above-mentioned high temperature pre-treatment step after the washing has a property stage by stage once, secondary, three times be with salt, three times the amount with salt is generally 1/10,3/10 and 6/10, as seen this traditional with the salt mode can cause technological process prolongation, energy consumption height equally, quantity of wastewater effluent is big and the yam surface filoplume can increase, and influences yarn evenness and fracture strength.In addition, divide three times with salt, operate very loaded down with trivial detailsly, the Artificial Control process repeats, and heavy (again) existing property is poor.
In view of the dyeing of the viscose cheese in the prior art existing above-mentioned two is short of greatly, so the applicant thinks and is necessary to be explored and improved.
Summary of the invention
Task of the present invention be to provide a kind of technological process brief and use shorten the production cycle, help energy savings and reduce sewage discharge and use the dyeing that embodies the desirable viscose cheese of energy-conservation and environmental protection, yarn evenness, filoplume, fracture strength.
Task of the present invention is finished like this, and a kind of dyeing of viscose cheese comprises and dyes preceding washing, dyeing, is characterised in that: washing is will to wash in normal-temperature water behind base yarn metal, the dress cage earlier before described the dying, and draining then obtains treating the dye bobbin yarn; Described dyeing is that unlatching circulation limit, dye vat working barrel back adds chelated dispersants, levelling agent, dyestuff successively inject the water yield of regulation bath raio in dye vat after, treat that dyestuffization will treat that dye bobbin puts into dye vat after even, the normal temperature insulation, in dye vat, circulate then with salt, and Control Circulation is with the heating rate in the salt process, be incubated, cooling then, be incubated again after the cooling, thereafter add alkali, and control add-subtract time, add alkali and finish the back and be incubated, discharge opeing obtains treating the dyed yarn of post processing.
In one embodiment of the invention, the time of washing is 2-5min before described the dying.
In another embodiment of the present invention, described metal is meant down yarn, and described yarn is meant the yarn on the paper twine pipe is fallen around to dyeing bobbin; Described dress cage is meant that the dyeing bobbin that will be wound with yarn is nested with on the sarong, and locks the top lock.
In another embodiment of the present invention, the weight part ratio that described regulation bath raio is yarn and water is 1: 6-10; The time of described normal temperature insulation is 10-25min, and works in the cycle alternation mode of positive pump 3min, anti-pump 4min.
In another embodiment of the present invention, described circulation is meant earlier with salt the dye liquor in the dye vat is introduced in the charging bucket by reflux pump, by charge pump the salt that stirs in the charging bucket is introduced in the dye vat, through circulating repeatedly until the salt in the charging bucket is all introduced in the dye vat again.
In yet another embodiment of the present invention, described heating rate is for to be warming up to 80 ℃ with 1-2 ℃/min, and the described temperature retention time that is incubated is 18-30min.
More of the present invention and among embodiment, described cooling is cooled to 60 ℃ for the rate of temperature fall with 2-3 ℃/min, the described time that is incubated again is 7-15min.
Of the present invention again also among embodiment, the described alkali that adds is to add alkali with 50% or 70% or 80% the alkali curve that adds, and the time that adds alkali is controlled to be in the 20-40min and adds.
In another embodiment again of the present invention, described to add the time that is incubated behind the alkali be 20-70min.
In again of the present invention and then embodiment, the pump power of described positive pump is 85%, and the pump power of described anti-pump is 90%.
The advantage of technical scheme disclosed in this invention:, saved the energy effectively and reduced sewage emissions, therefore both energy-conservation and environmental protection owing to saved to the high temperature pre-treatment step before the washing before dying; Since become in the prior art stage by stage with salt for circulation with salt, so shortened technological process and further saved the energy, and more can reduce the sewage emissions amount significantly; The resulting filoplume for the treatment of the post processing dyed yarn, bar are done, still can be consistent before fracture strength and the dyeing, and the COLOR FASTNESS ideal after dyeing.
