Abstract

The invention discloses an environment-friendly soaping agent for dyeing cotton fabrics with reactive dyes, a preparation method and application thereof, and belongs to the technical field of textiles. The technical problem to be solved in the present invention is to provide a low-toxicity, environmentally friendly biosurfactant sophorolipid in the use technology of reactive dye dyed cotton fabric soaping, to slow down or reduce the impact of cotton fabric soaping waste liquid on the environment. Pollution. Its technical scheme of the present invention is: a kind of soaping agent, and described soaping agent comprises following raw material according to parts by weight: 1-9 parts of sophorolipids, 1-9 parts of anionic surfactant, 1 part of soaping auxiliary agent ‑9 parts, the anionic surfactant is one of sodium dodecylbenzenesulfonate or rhamnolipid. The present invention utilizes the combination of sophorolipids, anionic surfactants, and soaping aids to further effectively improve the soaping fastness and rubbing fastness of plants, and at the same time, the soaping agent is environmentally friendly, biodegradable, and has a wide range of properties. Application prospects.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a soaping agent for cotton fabric dyed with reactive dyes, a preparation method and application thereof. Background technique [0002] Reactive dyes are widely used because of their bright color, complete color spectrum and low price. However, it is easy to form floating color when reactive dyes are used to dye cellulose fibers. The reasons may be as follows: ① When reactive dyes are used to dye cellulose fibers, some dyes are dyed on the fabric and combined with it by van der Waals force, and the other part of the dyes are in the alkali Under mild conditions, hydrolysis occurs to form hydrolyzed dyes; ②If the dye is used too much, it will accumulate on the surface of the fabric in the form of multi-layer associations, so that only the bottom dye molecules can react with the cellulose fiber to dye; ③ When the carbon atoms and active chlorine atoms in the dye molecules undergo d...
