For to the method for dyeing textiles and arrangement and corresponding intrument
Technical field
The present invention relates to for use the dye solution that is dissolved in liquefied ammonia to carry out to dye and method that arrangement is processed and Corresponding intrument.
The present invention is applied on fabric, supatex fabric, knitwear and yarn, is used for dyeing and substantially improving product Characteristic.
Background of invention
For a long time, in being intended to the arrangement of product performance of the textile that improvement is made up process of cellulose fibre, Study and apply the technique using liquefied ammonia bath.In this process, the temperature in the temperature of-34 DEG C, i.e. under atmospheric pressure ammoniacal liquor Under degree, with the liquefied ammonia dipping fabric persistently usual time being changed to 30 seconds from 1 second.
Due to ammonia to cellulose fibre apply swelling effect, there is the crystalline orientation of cellulose and fibre structure do not made Becoming the fact that destroy, the quality of fabric is improved.
When cellulose fibre is impregnated, the little molecule of liquefied ammonia not only penetrates and also penetrates through to knot to the amorphous area of cellulose In crystalline region, fracture hydrogen bond is so that fiber can complete swelling.It in the subsequent evaporation stage, with the generation of new hydrogen bond, was I type originally Cellulose be transformed into type III cellulose with certain percentage.
Specifically, with in liquefied ammonia dip time increase, cellulose from I type to the conversion of type III with progressive bigger Percentage proportionally occur.
The principal benefits being processed imparting cellulosic fabric by this arrangement is:
-silkiness gloss;
-more preferable dimensional stability;
-mechanical resistance increases;
The significant improvement of-non-ironing character;
-outward appearance is improved;
-fabric seems " newly ", is also even such after repeated washing;
-soft-touch;
-compatibility of dyestuff is improved;
-level dyeing.
Having shown that in textile industry, liquefied ammonia can use without any problem and recycle.On the other hand, environment is protected Regulations just becoming increasingly stricter, and this is to consider the good reason that liquefied ammonia is also used as solvent in dyeing is processed.
The dyestuff of textile dyeing is dissolved in liquefied ammonia in aqueous medium by many being used for, and therefore described method can be used Many fibers are dyeed.
It is related to water quality, water consumption and subsequent purification that the method utilizing the dyestuff being dissolved in liquefied ammonia to dye has eliminating Advantage of all the problems.Described method also eliminated such as wetting agent, electrolyte, softening agent, carrier, delayed-action activator and poising agent Numerous auxiliary products and chemical products.
File US 3 824 076 describes colouring method, it is mentioned that carry out the Minimum Sample of fabric in the lab Test.Within this document, textile material utilizes the ammonia solution being mainly made up of liquefied ammonia, dyestuff, caustic soda and water to dye.Literary composition Dyeing recipe described in part can in the test carrying out the small sample of fabric or knitwear effectively, but can not be industrially It is applied to a large amount of textile dyeings.
This is because, in usual commercial Application process fabric have uneven distribution humidity and can be at textile Various regions have irregular contraction, thus uneven and dyestuff also will be adequately secured to fiber by gained color.
It is an object of the invention to obtain for the commercial run of dyeing textiles and corresponding intrument, wherein dyeing is The ammonia solution containing dyestuff is utilized to carry out;The fixing benefit that described Combination of Methods is ensured by liquefied ammonia and dyeing The significantly saving of dyestuff, auxiliary agent, water and steam.
Applicant designs, tests and embodies the present invention to overcome the weak point of the state of the art and to obtain these With other objects and advantages.
Content of the invention
The present invention illustrates in the independent claim and characterizes, and dependent claims describe the present invention other characteristics or The variant of main inventive idea.
According to the present invention, come to dyeing textiles containing the ammonia solution being dissolved in dyestuff therein and simultaneously for utilizing The method arranging provides following steps:
-prepare the ammonia solution containing dyestuff and described solution is delivered to the machine for processing spinning material;Advantageously, The step preparing ammonia solution also includes controlling the percentage of the gross weight for the solution containing liquefied ammonia and water for the aqueous phase;
-before described textile material enters in processing machine, present in adjustment textile material, aqueous phase is for weaving material The percentage of material dry weight;
-make textile material enter in described machine through safety seal;
-utilize ammonia solution impregnation of textile materials at least several seconds, make textile material keep mechanical constraint unwanted to prevent Shrink;
-from the textile material still keeping mechanical constraint, extrude excess ammonia solution, in order to obtain and do relative to textile material Weigh about the adjustable pick up (pick-up) of 80%-100%;
-in processing machine, from the textile material still keeping mechanical constraint, evaporate ammonia completely;
-make dyed and dry textile material leave from processing machine through safety seal.
In a form of embodiment, after leaving from processing machine, textile material stands decatize circulation.
If carried out decatize can utilize saturated or overheated steam to enter in rolling steaming steam engine at atmospheric pressure, or at elevated pressure OK, it is used for being fixed to dyestuff fatefully textile fabric.
In a form of embodiment, when leaving from processing machine, textile material utilizes water and possibly also with soap Wash and stand the dyestuff that wash cycle removes the minimum percent being not fixed to fiber.
According to variant, the ammonia solution with dyestuff also comprises a certain amount of caustic alkali, and described caustic alkali is selected from such as hydrogen-oxygen Change sodium, potassium hydroxide or lithium hydroxide.
According to another variant, the ammonia solution with dyestuff also comprises a certain amount of sodium carbonate.
According to another variant, the ammonia solution with dyestuff also comprises a certain amount of distilled water.
In a form of embodiment, advantageously remain the ammonia solution of cooling in one or more grooves with add Work machine separates preparation.
Utilize said method, therefore may utilize the selected dyestuff being dissolved in liquefied ammonia and dye simultaneously and arrange all fibres Cellulose fiber (cotton, flax, hemp, jute, ramie and other), the mixture of described fiber, described fiber and synthetic fibers mixed Compound, staple fibre (viscose rayon, koplon (polynosic), Modal fibre, acetate fiber, triacetate Fiber, CUP and other), the mixture of staple fibre, the mixture of staple fibre and cellulose fibre, staple fibre with The mixture of synthetic fibers, animal derived fiber (wool, cashmere, mohair yarn, mohair, goats hair, silk and its It) and the mixture of animal derived fiber and all above-mentioned fibers.
Some synthetic fibers of such as polyamide are used as the present invention and dye.
Described technique is available to be kept under atmospheric pressure or under subatmospheric adjustable pressure or is being higher than Medium under the adjustable pressure of atmospheric pressure is continuously or non-continuously applied.
Used dyestuff is selected from the classification of reactive dye, direct dyes, disperse dyes, and sulfuration dye in lesser degree If material, acid dyes, metallization acid dyes and the previous classification through the reducing dye (vat dye) in the case of reduction.
Used dyestuff can be in powder type or the liquid form that has been dissolved in the water.
Known following humidity ratio:In wool 18.25%, cotton in 8.5%, in hemp 12%, in jute 13.75%, flax In 12%, in viscose rayon 13%, in acetate fiber 9% and triacetate in 7%.
The visual fiber source of humidity, the count of yarn, the weight of goods and type and other parameters and change.
Humidity also can change between the center of fabric and side or between the initial and end of same fabric.Humidity Also can in fabric non-uniform Distribution.
If there is identical weight and form, there is identical pick up but there is the various bafta profit of different humidity rate Impregnate with the dyestuff being dissolved in liquefied ammonia, then these fabrics in dyeing and will have different colours intensity after being dried.
The amino molecule penetrating to cellulose fibre makes cellulose fibre swelling and therefore also shortens.
For example, weight 120g/m2, combed yarn Ne the 80th, not by mechanical constraint, utilize relative to 150% liquid of bafta dry weight Almost shrink completely (about through upwards 10% with in broadwise 7%) of the bafta of ammonia pick up dipping occurs less than 4 seconds In.
Almost receiving completely of the same goods not impregnated relative to the pick up of its dry weight 100% by mechanical constraint, utilization Contracting occurs less than in 6 seconds.
Almost shrinking completely of the same goods not impregnated relative to the pick up of its dry weight 60% by mechanical constraint, utilization Occur less than in 12 seconds.
Determine pick up if had and do not utilized the dyestuff being dissolved in liquefied ammonia to impregnate by the fabric of mechanical constraint, then Dyed fabric can be between center and selvedge or to have different colours between the initial of goods and end strong after drying Degree, this phenomenon is because the material irregular thickening being produced by non-uniform shrinkage in each point at fabric.
In the method according to the invention, humidity is adjusted and is uniformly distributed in whole textile material, because with Each change of humidity during staining procedure, the concentration of the dyestuff being dissolved in liquefied ammonia directly will change on fiber, thus then There is corresponding different colours intensity in the zones of different of textile.
Due to this reason, according to the present invention, before with ammonia solution dipping, textile material drying is to have uniformly The humidity of the predetermined percentage of distribution.
Textile material can use the drier that relative overflow dyeing machine installs or alternatively by using stenter (rameuse) It is dried.It is adjustable and can be because of goods by moisture detector monitoring, the percentage by the water staying on textile material And it is different.By and large, in the animal derived fiber of cellulose fiber peacekeeping, it has been found that wet relative to fiber dry weight about 4%-5% Degree is favourable.
Remove water from the cellulosic textile materials not uniformly distributed containing a large amount of water or water, in order to obtain relative to spinning Knit the percentage of the residual humidity of material dry weight 4%-5%, be rapid and relatively simple process:On the contrary, evaporation is still being spun Present in textured fiber core, the water of last percentage is to spend time taking technique.
Due to this reason, for purposes of the present invention, stopping at the percentage showing referred to above is easily, described Percentage is also uniformly distributed in whole fabric or knitwear.In the case of synthetic fibers, residual humidity is about 0.5%- 1%, the dry weight relative to textile material again.
As described in us, in favourable solution, ammonia staining solution can be at one or many of service processing machine Prepared by individual groove;If under atmospheric pressure worked, then the solution temperature being ready for introduction in textile impregnation zone in the machine must Must remain very low, the condensing temperature of about-30 DEG C/-36 DEG C.
Can include based on the ammonia staining solution of dyestuff:
-mainly, liquefied ammonia;
-in terms of g/ rises the powdered dye being dissolved in solution of certain percentage, or in terms of cc/ rises a certain amount of containing The aqueous solution of dyestuff;
-possibly, the distilled water of minimum percent;In the case of dark color, wherein must increase in terms of grams per liter to be dissolved The weight of dyestuff, some powdered dye can have solubility issues in independent liquefied ammonia, and therefore must add certain percentage The water of ratio makes these dyestuffs solvable;The percentage of water can be relative to the gross weight of the solution containing liquefied ammonia and water from 3% change To 10%;
-possibly, the percentage of 2%, the causticity being concentrated into 50 Baumes can be changed to relative to the overall of solution from 0.5% Alkali;Described caustic alkali can be NaOH, potassium hydroxide or lithium hydroxide;
-possibly, the sodium carbonate of minimum percent or potassium carbonate.
In order to not suppress to be converted into the liquefied ammonia of type III cellulose and the reaction of cellulose fibre from I fiber type element, according to this Invention, preferably water, the water in i.e. intrastitial moisture and ammonia staining solution (adds to the possible distilled water of solution, possible dyestuff In water and the water in caustic alkali) all percentages, should be less than relative to the gross weight of the solution containing liquefied ammonia and water The maximum of 20%;Made a reservation for and during processing cycle described value monitored as fiber and to be dissolved in solution The function of dyestuff and select.In solution, the percentage of water can for example be monitored by electronic densitometer;Under atmospheric pressure, for example, 1 Rise water and weigh 1 kilogram, and 1 liter of liquefied ammonia weighs 0.682 kilogram.
In the solution substituting, before utilizing ammonia solution dyeing, textile material stand to utilize containing caustic alkali and The process of the aqueous solution of possible carbonate, afterwards by follow-up drying, thus stays containing of preset percentage upper on the textile State the moisture of salt.
For the characteristic improving dyeing amount and improve cellulose fibre, under 50 Baumes, the percentage of caustic alkali can improve About 5%-10% to total solution.
In fact, by improving percentage, define containing the ammonia solution selecting dyestuff and caustic alkali, it is therefore an objective to individually Carry out processing with liquefied ammonia and compare the mercerization effect increasing in cellulose fibre.
Process wool product if, with ammonia solution described above, then obtain the optimal fixing of all fibres.
Utilization present invention obtains multiple advantage, such as:
-cellulose fibre is collated;
-on the fiber surface with the level dyeing of fiber depths;
-bright;
-dyeing amount is high;In the case of reactive dye, reactive dye only with cellulose hydroxyl group and not anti-with water hydroxyl Should, in the case of as dyeed in aqueous medium;
-color fastness is very high;
-get rid of nearly all in aqueous medium dyeing present in chemical assistant;
-almost get rid of water completely;
-significantly save heat energy;
-do not have unwanted textile material to shrink;
-because ammonia be can recycle continuously with reusable, so dyeing with almost no pollution.

Dyeing and collating unit for textile generally and integrally to indicate by reference 10 in the accompanying drawings.
Dyeing and collating unit 10 include processing machine 11, wherein in this case, there is urn 12, and urn 12 is containing by 13 The dye solution being dissolved in liquefied ammonia of instruction.
Make to introduce in processing machine 11 through safety seal 15 with textile material 14 prepared by predetermined moisture, be ready to pass through The solution being immersed in dyestuff and liquefied ammonia dyes.
Before being introduced, textile material 14 is dried by two heating cylinder 16a and 16b, and then by cooling cylinder 17 cool down, and it reduce the temperature of textile material 14.
When leaving from cooling cylinder 17, still the percentage of the moisture on textile material 14 is supervised by moisture detector 18 Survey;In the case of cellulose fibre or animal derived fiber, residual humidity is advantageously maintained at relative to textile dry weight 4%-5%.
It is appreciated that for belonging to different types of fiber, and/or according to processing conditions, when leaving from drying unit Residual humidity value can be different from value illustrated above.
Then, make textile material 14 be immersed in urn 12, impregnate with the solution of dyestuff and liquefied ammonia.
In submergence and impregnation steps, and during the whole path in processing machine 11, textile material 14 is at first Tight holding mechanical constraint between roller 19 and the second idler roller 23, the first idler roller 19 is arranged in processing machine 11, enters close to it Mouthful, the second idler roller 23 is arranged in processing machine 11, close to its outlet.
Therefore, textile material 14 keeps under tension with required tensioning degree between roller 19 and roller 23.
In the case of shown here, the second roller 20 is partially immersed in the solution of dyestuff and liquefied ammonia and determines material of weaving Material 14 paths in urn 12, and be arranged on the outlet of urn 12, the 3rd electronic roller 21 coordinate with compression roller 22 carry out from Textile material 14 is removed excessive staining solution for the first time.
During impregnation steps, the little molecule of ammonia carries dyestuff and hydrate, the amorphous area of quick penetration to cellulose and Crystal region;Still suffer from moisture due in fiber, penetrated by swelling the promotion further of fiber.Textile material 14 roller 19 with In the case of keeping mechanical constraint between roller 23 and be in tension-adjustable, dipping occurs to continue generally about 2-in urn 12 The time of 3 seconds.
In order to ensure to stay in whole fiber equally distributed ammonia solution 13 relative to textile material 14 dry weight about 80%- The adjustable pick up of 100%, the goods leaving from dipping urn 12 are squeezed immediately between roller 21 and roller 22.
The adjustable pick up of the about 80%-100% of ammonia solution to be distributed is the optimum value preventing fibre deformation, Described fiber is under the swelling and condition of palsticity during extruding.
In solution shown here, when leaving from squeeze unit, textile material 14 stands drying cycles, wherein The ammonia of all existence is all evaporated, in order to only leave the water of dyestuff, caustic alkali and minimum on fiber.
Directly contacted the evaporation completely obtaining ammonia by the surface making textile material 14 lean against a series of heating cylinder 24, Heating cylinder 24 is under preset temperature and arranges one by one, advantageously all heating cylinders 24 all contact with each other.
In this step, the same with evaporation ammonia, present in fiber, the water of certain percentage is also heated at the temperature of about 100 DEG C Degree, so that the dyestuff of deposition is chemically pre-fixed or is fixed to fiber on textile material 14.
In fact, in the presence of hydrate, reactive dye to cellulose fibre fixing is due to water present in fiber Temperature raise and dyestuff and fiber self temperature raise.
Ammonia and possible steam are absorbed from drier by multiple pump units 25, are then transported to precooling Condenser is to be condensed subsequently to liquid by cooling unit.
In preferred solution, ammonia can condense to liquid subsequently in a known way again:Therefore gained liquefied ammonia will Again prepare to use for another.
After the drying step, make be dried and dyeing textile material 14 through safety seal 115 from processing machine from Open.
Operating pressure in processing machine 11 preferably remain in slightly under lower pressure to prevent NH_3 leakage in job site; In the solution of change, pressure is also positively retained under atmospheric pressure, or under keeping the discontinuous case of machines completely closing Under conditions of being in the adjustable pressure of superatmospheric.
In order to ensure or complete dyestuff fixing to fiber, after leaving from processing machine, textile material 14 can be at vapour Stand the decatize circulation carrying out by shown solution in steaming machine 26.
Decatizing machine 26 can utilize saturated steam or superheated steam for rolling steaming type.
Decatize circulation can be at atmospheric pressure or be under stress defined the time possibly.
Substituting in dyeing, after leaving from the arid region of processing machine 11, dyed textile material 14 is with containing Having caustic alkali and the aqueous impregnation of possible carbonate, and then decatize in steam engine, in described steam engine, dyestuff is solid Fixed to fiber.
At the end of decatize, reduce the dyestuff being not fixed to fiber of percentage by washing of carrying out in washing machine 27 Washing circulation preferably to remove, washing machine 27 includes the first washing machine utilizing hot water He may soaping in this case 28, being then followed by is the final washing in the second washing machine 29.
Wash time is of short duration and water consumption is extremely limited, even in the feelings with the cellulose fibre of reactive dyeing It is also such under condition, because the percentage being not fixed to the dyestuff of fiber is minimum.
The dyeing utilizing the ammonia solution of dyestuff to carry out yarn must be carried out from warp beam to warp beam, i.e. from untiing setting In the warp beam of the textile of processing machine 11 entrance, to the warp beam being wound around the dyed textiles being arranged on processing machine 11 outlet: In other words, yarn remains adjacent to and is wrapped in around sizeable warp beam.
It is evident that in the case of without departing from the field of the invention and scope, can be to method as described above and dress Put and modify and/or part interpolation.
