Description
Technical field
The invention belongs to stock-dye technical field, be specifically related to the method for a kind of calcium alginate fibre dyeing.
Background technology
Calcium alginate fibre is the novel biodegradable synthetic fiber of a class.The natural sea mosanom contained by algae in the raw material sources Yu Haiyang of this fibrid, then be prepared from by wet spinning technology.The type fiber not only has moisture absorption that traditional natural fabric has, softness, the feature such as insulation and biocompatibility, also there is because of its special structure and preparation technology excellent fire-retardant, antistatic and antibacterial characteristics, thus there is commercial application prospect widely.
But the main application of calcium alginate fibre present stage still concentrates on the industry such as medical dressing, mouth mask of non-garment industry, be mainly difficult to carry out dyeing and finishing by the type fiber and process caused by process.Prepared by the calcium ion in calcium chloride solidification liquid and the sodium ion generation ion-exchange in sodium alginate in calcium alginate fibre preparation process.Normal containing a large amount of sodium ions in tradition dyeing and finishing solution, if accelerant sodium sulphate, color-fixing agent sodium carbonate and all kinds of activity and direct dyes etc. are all containing sodium ion, the type fiber is caused usually again ion-exchange to occur, recover the gel state of its original sodium alginate, completely lose its every characteristic as fiber.In order to accelerate to realize the commercial application of calcium alginate fibre at garment industry, make great efforts to solve focus and the difficult point that this bottleneck problem of calcium alginate Colour Difference becomes research.
The method of existing solution calcium alginate fibre dyeing can be divided into following three classes substantially.
The first kind is the method adopting dope dyeing.Chinese patent CN104264280A discloses a kind of lake colours that adopt to the method for alginate fibre original liquid coloring, this application adds lake colours in alginate fibre spinning solution, after being uniformly mixed, obtain lake colours coloring spinning stoste after filtration after deaeration, prepare lake colours dyeing alginate fibre further.King's equality people adopts fluorescent pigment to carry out painted to alginic acid fibre stoste, and have studied its filming performance (fluorescent pigment on the impact of alginate fibre spinning solution and film properties thereof, textile journal, the fifth phase in 2015,48-53 page).
Equations of The Second Kind is the method for fibre modification.Chinese patent CN161736440A discloses a kind of manufacture method of stainable alginate fibers, and water-soluble dendrimer adds in alginate fiber spinning solution by this application, is obtained the alginate fibre with good dyeability by wet spinning.
3rd class for adopt existing directly and REACTIVE DYES alginic acid fibre is dyeed.Chinese patent CN101413207A discloses a kind of dyeing and finishing technology of alginate fibre fabric, describes the traditional dyeing process directly using REACTIVE DYES, realizes alginic acid fibre painted by the short dye of sodium sulphate and soda ash and tint retention; The people such as Kong Baoyun have studied and adopt calcium chloride to replace traditional sodium sulphate as the accelerant of reactive dyeing alginic acid fibre, to avoid sodium ion to the destruction of fiber, (the calcium alginate fibre reactive dyeing process that dyes has been carried out to alginic acid fibre, printing and dyeing, 8th phase in 2013,22-24).The people such as Lv Fangbing then adopt cerous nitrate to replace the method for sodium sulphate, adopt a few class REACTIVE DYES to complete dyeing (alginate fibre REACTIVE DYES rare-earths dyeing, the 24th phase in 2009,11-14) to alginic acid fibre.Chinese patent CN103981744A discloses a kind of salt-free dyeing technique of calcium alginate fibre, after this application adopts and first uses aluminum sulfate solution process to alginic acid fibre, re-use three kinds of direct dyes to its direct dyeing, the method finally adopting calcium chloride water to carry out fixation treatment dyes to alginic acid fibre.
Although the above-mentioned dyeing to calcium alginate fibre has been made and having been attempted valuably, many problems are still there is.Particularly in use conventional dyes dyeing course, still there is dye uptake not high, dye species is few and fiber is caused to the defect of damage etc.Dyeing course is more complicated relative to traditional dyeing, and causes using and wasting of a large amount of auxiliary agent.Therefore, the dyestuff being more suitable for calcium alginate fibre dyeing and dyeing is found to be still problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide that a kind of dye-uptake is high, strength loss is little and possess the colouring method of the calcium alginate fibre of higher soaping fastness after dye.
The colouring method of calcium alginate fibre of the present invention adopts the dyestuff containing polyethylene polyamine skeleton structure to dye to calcium alginate fibre.
Wherein,
The described dyestuff containing polyethylene polyamine skeleton structure is the one in following dyestuff, n=2 ~ 8.
Dyeing course is first dissolved in the water by the dyestuff containing polyethylene polyamine skeleton structure, then regulates its pH value to 3 ~ 5 to obtain dye liquor, finally added in dye liquor by calcium alginate fibre and dye.
The consumption of described polyethylene polyamine skeleton structure dyestuff is 1 ~ 5% of calcium alginate fibre quality, and the consumption of water is 10 ~ 30 times of calcium alginate fibre quality.
Acid is adopted to carry out pH value adjustment, preferred hydrochloric acid or sulfuric acid.
Described dyeing temperature is 30 ~ 60 DEG C, and dyeing time is 30 ~ 80min.
Adopt neutral soap lye soap boiling 10 ~ 15min at 90 ~ 95 DEG C of 1 ~ 4 ‰ after dyeing, fully wash, dry.
Beneficial effect of the present invention is as follows:
Dyestuff of the present invention and dyeing be deeply and on the comprehensive architecture basics analyzing calcium alginate fibre preferably and find out.Due to the hydroxyl of a large amount of negatively charged that contains in calcium alginate fibre and carboxyl, the fiber therefore in dye liquor is with a large amount of negative electrical charges.Based on this, the dyestuff that a class that the present invention is preferred contains polyethylene polyamine skeleton structure dyes to it.This dyestuff is owing to containing more primary amino radical and secondary amino group in the structure, and it can be converted into positively charged ammonium salts under mildly acidic conditions, thus makes dye molecule with more positive charge.Dyestuff can realize upper dye to fiber, infiltration and set by the effect of electrostatic attraction in dye bath, thus fundamentally avoid in conventional dyes dyeing course and need to add inorganic salts and urge to contaminate and this disadvantage of fibre damage of causing, after stock-dye, strength loss is little; Simultaneously, relative to the effect of intermolecular force more weak between general direct dyes and fiber and hydrogen bond, active force between this dye molecule and fiber is stronger, thus make it have the advantages such as higher dye-uptake and soaping fastness, fiber color after dyeing is even, bright-coloured, meets calcium alginate fibre coloration requirements.In addition, this dyeing is simple, convenient, mild condition, and does not need to add other metal ion and auxiliary agent, and with low cost, can realize the recycling of dye liquor easily, be a kind of colouring method of energy-conserving and environment-protective.
