Abstract
The invention relates to the dye printing process field, concretely relating to a soyabean protein fiber dyeing process, comprising the steps of: bleaching --> dyeing --> cooking with soap --> fixing color --> smoothly spinning, and thus improving the dyeing quality of the soyabean protein fiber, where the color is fresh and uniform, and the strength of the soyabean protein fiber is high. And it is applied to weaving and dye printing industries.
Description
Technical field
The present invention relates to the dyeing and printing process technical field, be specifically related to the dyeing of soybean fiber.
Background technology
Soybean fiber is a kind of aftergrowth azelon, mainly is made up of three parts.Outermost layer is a modified protein, the centre is the polyvinyl alcohol of part acetal, interior stamen is the polyacrylonitrile that contains the sulfonic group monomer, structurally contain amino, carboxyl and itrile group, similar wool of its physical and chemical performance and silk, but because that soybean fiber itself has is natural light yellow, if want to dye bright-coloured color and luster must improve soybean fiber white ℃.The sources of color that it is similar to tussah silk in the pigment of beans Hectometer and twain-aldehyde compound cross linking agent and acid polyethylene and soybean protein reactant color development institute such as amino acid extremely, the indyls of tryptophan especially wherein etc. are for its dyeing brings difficulty.
Soybean fiber is different to alkaline agent, oxidant, reductant, sensitivity such as damp and hot and xeothermic, not anti-concentrated acid, but in cold diluted acid, have only minimal amounts of dissolved, and alkali resistance is better, even in highly basic, also have only small loss, and antioxidant and reductant.But because the intensity of soybean fiber is low, the opposing higher temperature ability a little less than, changes of properties can take place under damp and hot state of temperature, and hard silk and doubling phenomenon appear in the spinning process afterwards, general soybean bleaching employing oxygen floats-reduces and floats two bleaching process and can obtain good effect in conjunction with brightening processing, but owing to can have fluorescent material in the whitening, so generally do not brighten processing.
The bleaching of soybean fiber is bigger than other fiber difficulty, weak effect.Traditional caustic soda hydrogen peroxide bleaching method is at high temperature to carry out, and the pH value of alkali lye should be between 10.5-11, but the pH value of soybean fiber is high more, and the high more intensity so of intensity can descend, and reduces the content of soybean protein.
Succeeding in developing of soybean fiber to textile industry has found a kind of new environmental protection fiber with good characteristic, but require dyed yarn to enter wherein along with market.Therefore, the dyeing of soybean fiber is to become an important link.But because soybean fiber is different with the composition of other fiber.Batch difference of raw material own and the doubling problem uniformity and its vividness official post product are affected on stream, utilize the traditional handicraft dyeing quality poor, and color is inhomogeneous, and can not guarantee the intensity of soybean fiber.
Summary of the invention
It is better that purpose of the present invention just provides a kind of soybean fiber whiteness, fibrous zero damage, the colouring processing method of the soybean fiber of the powerful and raising dyeing quality of raising fabric.
To achieve these goals, technical scheme of the present invention is: a kind of colouring processing method of soybean fiber is characterized in that: the technological process of soybean fiber dyeing according to the following steps: at first bleaching, dyeing then, soap boiling again is again along spinning.
The technological process of described soybean fiber dyeing is according to the following steps: bleaching → dyeing → soap boiling → fixation → suitable spinning.
Described bleaching is at first soybean fiber to be adorned cage, put into dye vat, by bath raio 1: 7-1: 15 to add pH values be the demineralized water of 8.5-10.5, presses 0.5-2 ℃ of/minute heating, in heating process, add defoamer and the 12--18 kilogram hydrogen peroxide that 10-15 kilogram oxygen floats auxiliary agent, 2-4 kilogram stabilizing agent, 0.5--3 kilogram by every double centner soybean fiber, be heated to 50-70 ℃, be incubated 20-60 minute, be heated to 75-80 ℃ again, be incubated 100-160 minute, bleed off pin water, change water and clean.
Described dyeing is: at first make dye liquor: add levelling agent, add dyestuff again, will stir when changing dyestuff, and dye liquor is filtered, make dye liquor; Under bath raio is no less than 1: 8 condition, add dye liquor then, heating, programming rate is with 0.5-2 ℃/minute, and temperature is not higher than 80 ℃, and gradation is slowly with salt, and behind the insulation certain hour, gradation adds alkali and carries out fixation again, is incubated fixation, cooling discharge opeing again.
Described dyestuff is a REACTIVE DYES.
Described soap boiling: at first want massive laundering before soap boiling, after striving for most of loose colour removed, the soap boiling temperature can not be higher than 80 ℃, adds the fine purifiation agent after the dilution, pH value greater than 7 condition under, further soap boiling again.
Described fixation is in some dark especially dyeing, carry out fixation treatment, after the color-fixing agent dilution, carries out fixation treatment under temperature 45-60 ℃ condition during fixation.
Described along spinning: as to be along after spinning agent and wanting dilute with water evenly to melt, add in the jar again, and temperature should be at 30-50 ℃.
The present invention adopts above-mentioned technology, at first utilizes oxygen to float auxiliary agent and has replaced highly basic, and pH value is 8.5-10.5, has reduced the pH value of the body lotion of soybean fiber, has improved the intensity of soybean fiber, and has kept the content of soybean protein; Press 0.5-2 ℃ of/minute heating simultaneously, add defoamer simultaneously, prevent that decomposing hydrogen dioxide solution is too fast, improved the utilization rate of hydrogen peroxide, make soybean fiber epidermis micro-structural obtain changing by above-mentioned technology, obviously improve dyeing speed and diffusivity, thereby improve Color, tinctorial yield also can improve 10%-15%; Next is to utilize suitable dyestuff, owing to contain certain hydroxyl in the soybean fiber, the amino acid of amino and carboxyl isopolarity gene, also have the hydroxyl on the uncrosslinked polyvinyl alcohol molecule of small part different to the affinity of dyestuff of the same race, the way key that solves is to select dyestuff, generally to select molecule little, the rate of just dying is low, the dyestuff that even dyeing and through-dyeing are good meets the dyestuff of this condition can be acid, neutral dye, the dyeing of proper soybean fiber, but consider that the fastness REACTIVE DYES is first-selected, to be the higher and dyestuff that contains reactive stronger active group of a kind of substantivity have very pile-on properties to soybean fiber for it, the dyeing of proper soybean fiber, its lifting performance on soybean fiber and to dye dark color all better, and soybean fiber is had higher substantivity for less salt type REACTIVE DYES.Suitable process conditions improves the dyeing quality of soybean fiber, and is bright in luster, even.
