Abstract
The invention discloses buffering type substitution alkali and a preparation method thereof. The buffering type substitution alkali is prepared from the following components in percentage by weight: 65% of potassium hydroxide, 17% of potassium carbonate, 10% of potassium citrate and 8% of acrylate. According to the buffering type substitution alkali, the color fixation rate is increased, an ingredient having the buffering property is added, so that process of color fixation of reactive dyes is slow, the color fixation uniformity is ensured in the state and the dyeing defect cannot be caused easily.
Description
Technical field
The present invention relates to a kind of substitute alkali and manufacture method thereof, particularly relate to a kind of buffer-type substitute alkali and manufacture method thereof.
Background technology
Substitute alkali can be called dyeing alkali, when substitute alkali is based on textile printing and dyeing reactive dyeing, substitute industrial soda fixation, use amount is 1/10th of soda ash, reduces COD of sewage (COD) value, production cost can be saved, reduce labor strength, substitute alkali Color is not good in the early time, is embodied in: color is too shallow, dyeing coloured light is out unstable, causes uneven color (look flower, two tone colour) than being easier to.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of buffer-type substitute alkali and manufacture method thereof, it is except promoting degree of fixation, slow fixation when adding acrylates with the composition of buffering property to ensure reactive dye color fixing, fixation can ensure that fixation is even in this state, not easily look flower.
The present invention solves above-mentioned technical problem by following technical proposals: a kind of buffer-type substitute alkali, is characterized in that, it comprises following component, by weight percentage:
The present invention also provides a kind of manufacture method of buffer-type substitute alkali, it is characterized in that, it comprises the following steps: add potassium hydroxide, potash, potassium citrate and acrylates successively to reactor, stirs 60 minutes, puts into 2KG plastic bag or 25KG plastic bag packaging.
Positive progressive effect of the present invention is: the present invention is except substituting traditional sodium carbonate, under the prerequisite that degree of fixation is close, ensure that reactive dye color fixing uniformity, product is originally with it with PH buffering property, fixation uniformity has exceeded sodium carbonate, can reduce product defect rate.
Detailed description of the invention
Buffer-type substitute alkali of the present invention comprises following component, by weight percentage:
Reactive dyeing sodium carbonate and substitute alkali fixation PH change contrast as shown in table 1.
Table 1
Note: 1. add alkali number of times three times, adds in 1/10,3/10,6/10 ratio respectively.
2. sodium sulphate plays short dye (colouring) effect when vital staining, alkali (sodium carbonate, a substitute alkali) tint retention, thus the colouring principle of REACTIVE DYES be first on contaminate fixation again.
By above-mentioned pH value change contrast, the initial pH value ascensional range of substitute alkali is little, and now the change of pH value has certain influence to fixation uniformity.PH value initially rises too fast, the quick set of dyestuff.Be unfavorable for even dyeing.From dyeing theory, when the pH value change of substitute alkali is favourable dye fixing, continue even look, to reach maximum even dyeing effect.
Fixation formula of liquid is as shown in table 2 below.
Table 2
The manufacture method of buffer-type substitute alkali of the present invention comprises the following steps: add potassium hydroxide, potash, potassium citrate and acrylates successively to reactor, stirs 60 minutes, puts into 2KG plastic bag or 25KG plastic bag packaging.
The present invention is except substituting traditional sodium carbonate, and under the prerequisite that degree of fixation is close, ensure that reactive dye color fixing uniformity, product is originally with it with PH buffering property, and fixation uniformity has exceeded sodium carbonate, can reduce product defect rate.
Those skilled in the art can carry out various remodeling and change to the present invention.Therefore, present invention covers the various remodeling in the scope falling into appending claims and equivalent thereof and change.
