Film-forming softener containing natural conjugated unsaturated fatty acid and preparation method of softener

Abstract

The invention relates to the field of research, development and application of natural dyeing and finishing auxiliaries, in particular to a film-forming softener containing natural conjugated unsaturated fatty acid. The film-forming softener is composed of the following substances in percentage by weight of 0.5%-12% of conjugated octadecatrienoic acid such as trichosanic acid, punicic acid, calendic acid, jacoumaric acid and conjugated linolenic acid or octadecadienoic acid such as conjugated linoleic acid or esters thereof extracted from trichosanthes kirilowii seeds, 12-1% of fatty acid ester quaternary ammonium salt, 1-10% of a hibiscus leaf water extract solution, 0.01-0.5% of litsea cubeba oil, 0.2-1% of moringa oleifera oil, 0.5-8% of a chitosan aqueous solution, 0.01-0.05% of konjac glucomannan, and 85.78-67.45% of purified water. Compared with the prior art, the film-forming softener has the beneficial effects that a plant dyed fabric can be soft and plump in hand feeling, the weather resistance is improved, and the color fastness to light is higher than the grade of 0.5-1. The film-forming softener is suitable for natural textiles such as cotton, hemp, silk, wool and the like, and regenerated cellulose fiber textiles such as tencel, modal, viscose and the like, and is particularly suitable for softening processing of plant dyed textiles containing the raw materials.

Description

technical field [0001] The invention relates to the field of research and development and application of natural dyeing and finishing auxiliaries, in particular to a film-forming softener made of natural conjugated unsaturated fatty acids, such as trichosanthenic acid extracted from trichosanthes seeds or punicic acid extracted from pomegranate seeds. Background technique [0002] Although plant dye dyeing technology has made some progress in recent years, a large part of the color of plant dye textiles has not been applied in large quantities, mainly because the natural colors of plant dye dyed textiles are easily affected by nitrogen oxides, ozone, etc. in the air. Oxidative damage is also easily decomposed by ultraviolet light. Commonly used petrochemical softeners will also aggravate this process, so that the weather resistance and light fastness of textiles dyed with vegetable dyes cannot meet the standards for industrial applications.
