Description
Technical field
Patent of the present invention is related to a kind of dyeing and finishing technology, and in particular to a kind of cotton black cheese dyeing and finishing technology.
Background technology
Cotton black cheese dyeing and finishing traditional handicraft is as follows：Preceding winder → dress cage → pre-treatment → hot water wash → removal dioxygen
Water → dyeing → cold water is washed, and → cold water is washed → neutralizes → soaping for the first time → soaps for the second time → and hot water wash → cold water washes → fixation
Cage → centrifugal dehydration → drying → inspection → packaging is examined → unloaded to → softness →.Concrete technology flow process figure is as shown in Figure 2：
The technique weak point shows following several respects：Firstth, pre-treatment and dyeing, neutralize and soap and fixation and soft
Soft technology is separately carried out.So, the consumption for water, electricity, vapour can accordingly increase, according to above-mentioned traditional handicraft, 13 cylinder water altogether,
By current method equipment 1 is totally submerged using most:7 bath raio is calculated, and 91 tons useless need to be discharged by completing the dyeing and finishing of 1 ton of cotton yarn
Water, technological process length, is unfavorable for energy-conservation, emission reduction, consumption reduction；Secondth, the production technology time is grown.Do not considering cheese, dye material
Enter cylinder, go out cylinder and water inlet, drainage situation under, complete traditional dyeing and finishing technology time be 444 minutes, add up to 7.4 hours；The
3rd, in fixation treatment and soft finish, the layer difference of cotton black cheese can aggravate.
The content of the invention
The purpose of the present invention is for problem present in above-mentioned, there is provided a kind of black cheese dyeing and finishing technology comprehensively.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following proposal：A kind of cotton black bobbin is yarn-dyed
Whole technique, concrete technology comprise the following steps：Preceding winder → dress cage → pre-treatment, the same to bath → hot water wash → of dyeing neutralize, soaped
With bathe → soap for the second time → hot water wash → cold water wash → fixation, soft softening one-bath → examine → unload cage → centrifugal dehydration → drying →
Inspection → packaging；
Wherein the first cylinder water：Pre-treatment, dyeing are with bath process using 60 DEG C of constant temperature, the same bath of all-in method, and wherein cheese is set
Standby variable-frequency motor operation uses positive three anti-four：Cheese is first hung in tube cylinder, intake, after adding 90~120g/L glauber salt,
1~2g/L chelated dispersants, 1~2g/L cottons levelling agent and 2~4g/L scouring and dyeing scouring agents are added, three circulations are kept
21min, i.e., after each circulation is 7min, 25g/L soda ash is added, after keeping four circulation 28min, be eventually adding reactive black dye
With light modulation reactive dye, then 6~8 circulations are incubated, 42~56min of holding；
Second cylinder water：Hot water wash technique, temperature 60 C, time 21min, with half cylinder water, positive pump operation, i.e. 1 ton of yarn exist entirely
Produced in 1000kg cheese, be totally submerged method by bath raio 1:7 adjust, it is necessary to 7 tons of water, and use half cylinder water, then are 3.5 tons
Water；
3rd cylinder water：Neutralize, soap merges technique for the first time, under normal temperature condition, add 1g/L 99% glacial acetic acid with
And 2g/L soaping agent, using half cylinder water positive pump operation entirely, 95 DEG C are warming up to 1.5 DEG C/min, and 21min is incubated, draining；
4th cylinder water：Soap for the second time, under normal temperature condition, add 2g/L soaping agents, using half cylinder water positive pump operation entirely, with
1.5 DEG C/min is warming up to 95 DEG C, and is incubated 21min, draining；
5th cylinder water：80 DEG C of hot water wash, under normal temperature condition, using half cylinder water positive pump operation entirely, it is warming up to 1.5 DEG C/min
95 DEG C, and 21min is incubated, draining；6th cylinder water：Normal temperature is washed, using half cylinder water positive pump operation 14min entirely, draining；
7th cylinder water：Fixation, soft softening one-bath, under normal temperature condition, 0.1~0.2g/L soda ash is added, adjusts the pH for the treatment of fluid
For value to 7.5~8.0, using half cylinder water, positive pump transports 14min entirely, 1~3% smooth agent, 3~6% softening agents is then added, with 1.5
DEG C/min is warming up to 50 DEG C~55 DEG C, complete positive pump operation 14min, add 0.1~0.3 g/L 99% glacial acetic acid, 1~
3% aldehyde-free colour stabilizer, complete positive pump operation 14min, draining.
It is above-mentioned for cotton black cheese, be using purpose sour after first alkali：Reduce fixation, it is soft when caused cylinder
Sub- yarn layer is poor, and its mechanism is：Because smooth agent, softening agent are mostly weak cation surfactant, the work of upper dye cellulose fibre
Property dyestuff be anion, ionic bond combine it is very fast, thus, cheese internal layer can be caused deeper, it is poor finally to produce certain layer.
Before soft finish, add soda ash, adjust the pH value for the treatment of fluid to 7.5~8.0, smooth agent, softening agent on this condition, and without
There is positive charge, thus in hand feel finishing, smooth agent, the softening agent adsorbed in fiber surface is relatively uniform, runs one section
After time, glacial acetic acid and aldehyde-free colour stabilizer are added, the purpose for adding color fixing agent is to adjust the pH value for the treatment of fluid again to weak acid
Property, smooth agent, the softening agent for making to remain in treatment fluid are positively charged, increase its adsorption rate to fiber, with augmentor fiber
Feel, the purpose for adding aldehyde-free colour stabilizer are to improve the washing color fastness of cotton black cheese.
Preferably, the pre-treatment, dyeing are more than or equal to the reactive black dye Z% (o.w.f) added in bath process
5% (o.w.f).
Existing technology is compared, and advantages of the present invention is as follows：Firstth, the dyeing of cotton black cheese, 60 DEG C are employed
Constant temperature, all-in method dyeing；Secondth, neutralization and first time are soaped and be combined into one；3rd：9 cylinder water are saved, i.e., cotton per ton is black
63 tons of waste water of color cheese emission reduction, meanwhile, give up pretreatment process completely, reduce the consumption of steam, electricity, after optimization
In technique, scouring and dyeing scouring agent is employed, after being processed, the capillary effect of all cotton fibers cellulose fiber can meet active dye completely
Expect the requirement of dyeing；4th, reduce the production time, save for nearly 45% time, improve production efficiency, do not consider cylinder
Sub- yarn, dye material enter cylinder, go out cylinder and water inlet, drainage situation under, the time for completing dyeing and finishing technology after the optimization is 245 minutes,
It is total 4.08 hours；5th, for cotton black cheese, using sour after first alkali, reduce fixation, it is soft when caused bobbin
Yarn layer is poor.
