Problems solved by technology

The traditional process of pretreatment is desizing, scouring and bleaching three-step method. This three-step method has the problems of long process route, low efficiency, large equipment occupation, and large energy consumption. With the continuous rise of energy prices, pretreatment The process is developed into one-step deboiling or one-step deboiling and bleaching. In order to meet the production needs, it is usually necessary to add a penetrating agent while adding a refining agent to the working fluid.

Embodiment 1

[0017] A preparation method of unsymmetrical bisamide sulfonic acid phosphate, comprising the following steps:

[0018] 1. Add 1.0 mol ricinoleic acid and catalyst potassium hydroxide (according to 1.5% of the mass of ricinoleic acid) into the reactor equipped with condenser, thermometer and stirrer, start stirring, and raise the temperature to 90°C under the protection of nitrogen. Slowly add 1.1mol triethylenetetramine dropwise to the reactor, and the dropwise addition is completed within 1 hour, then react at a constant temperature of 150-160°C for 6 hours, cool to room temperature, and obtain an intermediate monoamide, and then add 1mol dehydroabietic acid, start stirring, heat up to 90°C under nitrogen protection, then react at a constant temperature of 150-160°C for 6h, cool to room temperature, use 150# solvent oil and butanone mixed solvent (volume ratio 1:1) Recrystallize 3 times, remove by-products, dry in a vacuum drying oven at 60°C to constant weight, and obtain a...

Abstract

The invention discloses a high-efficiency environment-friendly penetrant for fabric pretreatment (asymmetric Gemini surfactant) and a preparation method thereof. The asymmetric Gemini surfactant is particularly an asymmetric bisamide sulfonate phosphate of which the structural formula is disclosed in the specification, wherein R is phosphate, and M is Na or K.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a fabric penetrating agent and a preparation method thereof. Background technique [0002] The penetrating agent can promote the rapid wetting of the fiber or fabric surface by water and penetrate into the fiber interior. Therefore, penetrating agents and wetting agents are not only mainly used in pretreatment processes such as desizing, scouring, mercerizing or bleaching, but also widely used in printing and dyeing and finishing processes. With the development of production, high efficiency, energy saving, time saving, shortening process and stable quality have become the common goals pursued by printing and dyeing factories. The traditional process of pretreatment is desizing, scouring and bleaching three-step method. This three-step method has the problems of long process route, low efficiency, large equipment occupation, and large energy consumption. With the continuous ri...
