Description
Technical field
The present invention relates to the preparing technical field of high-substitution carboxymethyl Cassia bean gum printing paste with active dye, relate in particular to the carboxymethyl Cassia bean gum of a kind of solvent method preparation height replacement and for printing paste with active dye.
Background technology
Printing paste with active dye is all the time main based on sodium alginate thickener, along with the increase of thickener materials, sodium alginate price constantly rises, simultaneously undue exploitation Sargassum, the problem that also result in environmental protection aspect, this promotes us to develop new printing gum to replace sodium alginate.In recent years, construction features according to sodium alginate develops carboxymethyl cellulose, carboxymethyl starch, carboxymethyl guar gum, alleviate the demand pressure to sodium alginate to a certain extent, but these thickeners have applied defect mostly, carboxymethyl starch salt stability is poor, and the molecular weight of carboxymethyl cellulose and carboxymethyl guar gum is relatively big, big with cellulose affinity, the feel of PRINTED FABRIC is poor, and sodium alginate there is also the problem that tinctorial yield is not high.The thickener developing new printing quality good is necessary.
Semen Cassiae housing quality is 27%, endosperm 32%, plumule 41%, taking in the powder made by its endosperm after removing shell, main component is the mixture of polysaccharide, and relative molecular mass is about 210,000, wherein cold water solubles is 22.8%, and hot water soluble is 50.8%(80 DEG C), water-insoluble 27.93%.Cassia seeds polysaccharides have water insoluble matter content height, can not Fast-swelling and hydration, dissolution velocity slow, and viscosity is wayward, electrolyte-resistant, endurance of cutting are more weak, be easily biodegradable, be difficult to the shortcomings such as long-term preservation, aqueous solution color be deeper, limits the further application of cassia seeds polysaccharides.Therefore, cassia seeds polysaccharides is carried out chemical modification, improve its water solublity and easily biological-degradable is very important.
The research of conventional Semen Cassiae focuses primarily upon the aspects such as its composition, pharmacology, structure, extraction process and food applications, and Semen Cassiae polysaccharide chemistry study on the modification is less.At present, only having a small amount of several sections of papers and carry out the carboxymethyl-modification of cassia seeds polysaccharides using isobutanol as disperse medium, substitution value is all less, and cold water insoluble matter is more, and saturating net is poor.Research is concentrated mainly in the structure of modified technique and modified sample and the analysis of solution property, and its introducing in practical application performance is less.The present invention mainly adopts solvent method using ethanol water as disperse medium, and Cassia bean gum is carried out carboxymethyl-modification, improves its cold water soluble, saturating net and rheological property so that it is meet the requirement of printing paste with active dye.
Summary of the invention
The preparation method that it is an object of the invention to provide a kind of novel environment friendly printing paste with active dye, to alleviate the demand pressure of sodium alginate, improves the effect of printing with reactive dye product simultaneously.The saturating net of carboxymethyl Cassia bean gum of prepared high substituted degree is good, and the color strength of Printing is high, is a Green environmental protection, resourceful modification of polysaccharides thickener, it is possible to replace sodium alginate as printing paste with active dye.
A kind of preparation method of carboxymethyl Cassia bean gum printing paste with active dye, this preparation method comprises the following steps:
(1) sodium hydroxide solution that mass fraction is 45% is cooled to room temperature, join the alcoholic solution being in the ethanol of stirring to obtain sodium hydroxide, under stirring, Semen Cassiae rubber powder, quaternization 30min ~ 60min when 28 ~ 32 DEG C is added in the alcoholic solution of sodium hydroxide；
(2) quaternization adds monoxone after terminating, and is warming up to 65 DEG C ~ 75 DEG C, carries out etherification reaction 3 ~ 3.5h after stirring；
(3) after etherification reaction terminates, it is cooled to 28 ~ 32 DEG C, regulates the pH of reaction system to neutral with hydrochloric acid, after washing, sucking filtration, drying, pulverizing, obtain carboxymethyl Cassia bean gum printing paste with active dye.
With the quality of Semen Cassiae rubber powder for benchmark in described step (1), 1g Semen Cassiae rubber powder needs the volume of ethanol to be 2 ~ 2.5mL.
With the quality of Semen Cassiae rubber powder for benchmark in described step (1), 1g Semen Cassiae rubber powder needs monoxone 0.006mol ~ 0.009mol.
The ratio of described sodium hydroxide and chloroacetic amount of substance is 2 ~ 2.2:1.
In described step (1), concentration of alcohol is 95%.
The substitution value of the carboxymethyl Cassia bean gum printing paste with active dye that described step (3) obtains is 0.8 ~ 1.1.
Drying temperature in described step (3) is 80 DEG C.
Beneficial effects of the present invention: the main component of Cassia bean gum is the mixed system of polysaccharide, wherein contain more cold water insoluble matter, acid and alkali-resistance less stable, saturating net also extreme difference, do not meet the requirement of printing paste with active dye, its application performance must be improved by chemical modification.By carrying out carboxymethyl modified to Cassia bean gum, its saturating net, rheological property and solubility property have bigger improvement.Along with the increase of degree of substitution by carboxymethyl, cold water insoluble matter gradually decreases, and the saturating net performance of thickener has greatly improved, and substitution value thickener solution more than 0.9 can easily through the screen cloth of 300 orders；Along with the increase of carboxymethyl Cassia bean gum substitution value, water solublity increases, and the stamp Viscosity Index of thickener becomes big, and the change of Viscosity Index is conducive to greatly improving the speed of ROTARY SCREAM PRINTING；Due to the hydrophilic carboxymethyl functional group introduced in macromole, the crystal region of Cassia bean gum is also destroyed to a certain extent simultaneously, and enhanced dissolution rate, the uniformity of serosity is preferably；The introducing of more carboxymethyl functional group so that it is water solublity improves, and is easily washed with water removing after stamp fixation, de-paste rate is high, and the feel of fabric is better.By the printing with reactive dye Experimental comparison with sodium alginate, it has been found that the general relatively sodium alginate of the surface tinctorial yield of its stamp product is high, it is possible to substitute sodium alginate for printing trial.And Cassia bean gum abundant raw material, price are relatively cheap, can biodegradation, when environmental problem is increasingly subject to pay attention to, this invention meets the requirement of ecological, environmental protective, and this result of study has also expanded the purposes of Cassia bean gum, and industrial value is high.
