Embodiment 1

[0053] Add 0.02mol aliphatic amine polyoxyethylene ether 1815 into a three-necked flask equipped with an electric stirrer and a condensing reflux tube, start stirring, heat up to 90°C, and slowly add (3-chloro-2-hydroxypropyl ) an aqueous solution of trimethylammonium chloride (wherein, the mass fraction of (3-chloro-2-hydroxypropyl) trimethylammonium chloride is 65%, and the molar weight is 0.04mol), after the dropwise addition is completed, the reaction Cool the system naturally to room temperature, filter the reaction product with suction, wash the resulting filter residue with ethanol for 3 to 5 times, dry at 50 to 70°C to constant weight, and crush it into powder to obtain a white powdery antifouling agent product. Anti-stain agent and anionic surfactant SDS, non-ionic surfactant Pingping plus O-25 are compounded according to the ratio of 28%: 2.5%: 22% (the rest is water) to prepare acid dye anti-stain soaping agent .

Abstract

The invention provides a biquaternary ammonium salt type acid dye anti-staining agent and a biquaternary ammonium salt type acid dye anti-staining soaping agent prepared from the same, and further discloses a preparation method of the anti-staining agent and a preparation method of the anti-staining soaping agent. The preparation method comprises the following steps: heating fatty amine polyoxyethylene ether, adding (3-chloro-2-hydroxypropyl)trimethyl ammonium chloride into the fatty amine polyoxyethylene ether, then cooling a reaction system, carrying out aftertreatment to obtain the anti-staining agent, and further compounding the anti-staining agent with a surfactant to obtain the anti-staining soaping agent. According to the invention, fatty amine polyoxyethylene ether is quaternized by a quaternization reagent (3-chloro-2-hydroxypropyl) trimethyl ammonium chloride to prepare the acid dye anti-staining agent with a biquaternary ammonium salt structure, wherein the reaction conditions are mild, the process is simple and easy to control, the conversion rate is high, and the acid dye anti-staining agent is suitable for industrial production; and raw materials are low in price, no extra organic solvent is needed in the preparation process, aftertreatment is simple, the preparation cost is low, and safety and no pollution are achieved.

Description

technical field [0001] The invention belongs to the technical field of synthesis of textile printing and dyeing auxiliaries, and in particular relates to a biquaternary ammonium salt type acid dye anti-fouling agent, an anti-stain soaping agent and a preparation method thereof. Background technique [0002] Wool fiber is an important raw material for the textile industry. It has the advantages of good elasticity, good warmth retention and strong hygroscopicity, and has made important contributions to the development of my country's textile economy. However, the staining phenomenon in the washing process after dyeing wool fabrics with acid dyes will cause problems such as non-white ground, pattern shade change or color fastness decrease, which seriously affects the quality of products. In order to effectively improve the quality and market competitiveness of wool fabrics, and reduce the consumption and discharge of washing water, people need to develop acid dye anti-stain soa...
