Abstract
The invention discloses a dyeing method, and particularly relates to an organic alkali dyeing method for a wool yarn. The method comprises the following steps: a pretreatment technology, a dyeing technology, a fixation technology, a soaping technology, a hot washing technology, a neutralizing technology, and a baking technology. According to the dyeing method disclosed by the invention, traditional inorganic bases, such as caustic soda and sodium carbonate, are replaced by organic bases, so that the safety coefficient of an active dye is effectively improved, the dyeing defect is not easily generated, the pH value in the dyeing process is stable, the possibility of chromatic aberration caused by pH value fluctuation of a dye bath is lowered, the wool yarn is good in hand feeling and vivid in color and luster, the dyeing defects of white spots, whiting and the like caused by incomplete cleaning are overcome, the dyeing quality is greatly improved, the chemical oxygen demand (COD) discharge of wastewater is further reduced, and the environmental pollution is small.
Description
Technical field
The invention discloses a kind of colouring method, especially relate to a kind of wool yarn organic base colouring method.
Background technology
At present in dyeing and printing products cellulose dyeing, mostly application of active dyestuff, and cellulose is inactive in general neutral medium, only, in alkaline medium, could play covalent bond and fixation with dyestuff generation nucleophilic displacement of fluorine or addition reaction.In traditional handicraft, the normal fixation alkaline agent using mainly contains caustic soda, tertiary sodium phosphate, sodium metasilicate, soda ash etc.Wherein use in factory with soda ash at most.But in actual production, soda ash consumption is very large, poorly water-soluble, easily caking stops up charge pipe, makes troubles to operation.If material thoroughly can not cause band, alkali is irregular, makes yarn produce look flower, and often because containing and produce hickie compared with multi-carbonate in dye bath, affects dyeing quality.
For preventing in dyeing course, because soda ash consumption makes greatly the too high generation hickie of carbonate content in dye bath, adding the post processing washing step after having dyeed, cause like this consumption of water, electricity, gas large.And soda ash dyeing COD discharge capacity in waste water after dyeing is high, and contaminated environment is serious.
Summary of the invention
The object of the invention is the deficiency in order to solve above-mentioned technology, adopt organic base to replace traditional inorganic base such as caustic soda, soda ash, effectively raise the safety coefficient of REACTIVE DYES, be difficult for producing look flower, in dyeing course, pH value is more stable, reduce the possibility that produces aberration due to the fluctuation of dye bath pH value, make wool yarn feel better, color and luster is more bright-coloured, solve because of the cleaning dirty dyeing defect such as hickie, white powder causing, dyeing quality improves greatly, further reduces waste water COD discharge capacity, and environmental pollution is little.
In order to achieve the above object, the designed colouring method of the present invention is as follows:
(1) pretreating process: under normal temperature, wool yarn is placed in to dye vat, and puts into REACTIVE DYES, auxiliary agent etc. soak 15-30min;
(2) dyeing: pretreated wool yarn is warming up to 60-70 DEG C of left and right by normal temperature, and heating rate remains on 0.5-1 DEG C/min, dyeing 40-80min;
(3) color fixing process: add organic base fixation, the concentration of organic base is remained in the scope of 1.5-3g/L, want slowly evenly in organic base adition process, the time is controlled at 30min left and right, insulation 60-80min;
(4) technique of soaping: temperature drops to after room temperature, and draining liq adds soaping agent to clean 10-15min;
(5) hot water wash technique: be to clean 15-20min at 80-90 DEG C in water temperature;
(6) in and technique: slowly add acid neutralization in the liquid of step (5), process temperature is controlled at 50 DEG C of left and right;
(7) dry: the wool yarn after above-mentioned treatment step is dried.
Described organic base is triethanolamine.
The present invention has effectively reduced the discharge capacity of dyeing waste water COD, has met the demand of modern production and environmental protection, meets the demand for development of national energy-saving, reduction of discharging, environmental protection, will increase new vitality to dyeing, has reduced the processing cost of dyeing and printing products.
