Abstract

The invention provides an environmentally-friendly Setaria viridis softening agent preparation method, which comprises: washing Setaria viridis, drying, crushing, and screening; adding petroleum ether, and extracting; filtering, and distilling to remove the petroleum ether to obtain an extract A and filtering residue; adding the extract A to a NaOH solution in a dropwise manner, and carrying out areaction; cooling, adding hydrochloric acid in a dropwise manner, carrying out thermal insulation, carrying out standing layering, taking the upper layer liquid, washing, and carrying out rotary evaporation to obtain a component B; carrying out a stirring heating reaction on the component B, stannous oxide and oxalyl chloride; carrying out cooling pressure reducing thermal insulation, and coolingto obtain a component C; taking the filtering residue, adding an ethanol aqueous solution, and carrying out water bath heating reflux; filtering to obtain an extraction liquid, carrying out adsorption decoloration, and carrying out pressure reducing distillation to obtain a component D; and mixing and stirring the component C and the component D to obtain the product. According to the present invention, the prepared environmentally-friendly Setaria viridis softening agent has good softness to the cloth, does not irritate to the skin, and further has characteristics of soft hand feeling, strong smoothness, good wettability and good softening effect.

Description

technical field [0001] The invention relates to a preparation method of an environment-friendly foxtail softener. Background technique [0002] Textile auxiliaries are very important to increase the added value of textiles. Among them, soft finishing, as an important finishing process in printing and dyeing, plays a very important role. During the processing of textiles, the handle will become rough after repeated treatments, and the synthetic fiber fabrics are generally worse, especially the microfiber fabrics. In order to make the fabric have a soft, smooth and comfortable feel, it needs to be finished. At present, it is widely used to finish with a softener. In addition, a large amount of softeners are used in the process of chemical fiber spinning, spinning and weaving of various fibers. The friction between them increases, which is prone to scratches, streaks and other phenomena. The use of softener can make the fiber itself have softness and smoothness suitable for ...
