A1
Abstract:
Disclosed are a buffering agent for balancing a pH value of fabric and a preparation method therefor. The buffering agent consists of a mixed aqueous solution of a carboxylic acid polymer and salt thereof, inorganic salt, and a penetrating agent, and the solvent is water; the weight ratio of the mixed aqueous solution of the carboxylic acid polymer and the salt thereof, the inorganic salt, and the penetrating agent is 35-45:5-8:8-10, and the solid content is 30-40%. The preparation method comprises: adding the mixed aqueous solution of the carboxylic acid and the salt thereof into deionized water, and uniformly stirring; then, adding the penetrating agent, and uniformly stirring; and finally, adding the inorganic salt, and uniformly stirring; additionally adding deionized water until the solid content is 30-40%, and standing for 24 hours. By means of the buffering agent, the pH value of a cloth cover can be neutralized and adjusted in the textile dyeing and finishing process, the pH value of finished product fabric in the storage process is maintained, the colored light of processed fabric does not change, and the cloth cover is also free of peculiar smell.
