Benefits of technology

This patented technology allows for improved fabrics that have good color fastness when dyed on them without losing their effectiveness over time due to factors like water washing or sunlight exposure.

Problems solved by technology

This patented technical problem addressed in this patents relates to finding ways for reducing the amount of expensive chemicals needed during dye production without sacrificing quality control standards (QC) compliance requirements. Specifically, there was an issue where certain types of chemistry were added that could affect how well dyestuff bindings onto fibers while also causing damage from excessive heat treatment processes such as steam-heater bleaching steps.

[0026] Fabric: Pure cotton bleached cloth

[0027] Dye: reactive red X-3B

[0028] Configuration of cationic modification solution and cationic modification of cotton fabric:

[0029] Dissolve 80 parts of cationic modifier in 1000 parts of water, add 34 parts of NaOH (or potassium hydroxide) after the solution is clarified, stir to dissolve and clarify. Put in 33 parts of fabric, set the temperature, keep warm at 60°C-90°C for 1-1.5h, take out the fabric, wash it with water, dry it, and set it aside.

[0030] Dyeing of modified cotton fabrics:

[0031] Dissolve 0.67 parts of reactive red X-3B in 1000 parts of water, put it into the modified cotton fabric, set the temperature, keep it warm at 60℃~90℃ for 0.5~1h, take out the fabric, soap and dry it.

Embodiment 4

[0040] Add 67 to 73 parts of concentrated hydrochloric acid with a mass fraction of 37% in a reactor equipped with an electric stirrer, dropping funnel, condenser and thermometer, and add 110 parts of a mass fraction of 33% trimethylamine aqueous solution dropwise under stirring conditions, and control The reaction temperature does not exceed 30°C, the dripping is completed in 1-1.5 hours, and the reaction is continued for 0.5-1 hour. After the reaction is completed, evaporate, crystallize and dry to obtain the intermediate trimethylamine hydrochloride.

[0041] Put 57 parts of the intermediate into the reactor, add 170-280 parts of absolute ethanol as a solvent, add 53-56 parts of epichlorohydrin into the dropping funnel, start the stirrer, and heat in a water bath. When the temperature rises to 40°C, start to add epichlorohydrin dropwise, finish dropping in 0.5 to 1 hour, and continue the reaction for 0.5 to 1 hour. After the reaction was completed, it was vacuum filtered a...

Abstract

The invention discloses a cellulose fiber cation modifier, a preparing method and a usage thereof. The preparing method comprises the following steps of: generating intermediate trimethylamine hydrochloride from the reaction between concentrated hydrochloric acid and trimethylamine aqueous solution, and reacting trimethylamine hydrochloride with epichlorohydrin under the condition of using ethanol as solvent in order to obtain the products. The cellulose fiber cation modifier prepared with the method has good textile dyeing property and has a percent conversion of between 87 and 90%. The cation modifier is used for reacting with natural polymer compound, such as starch, cellulose, lignin, chitosan, and the like, so as to generate cation type biodegradable macromolecule which is widely applied to the fields of paper making, spinning, oil industry, sewage treatment, and the like.
