Problems solved by technology

However, the modification effect of common cationic modifiers is poor, the dye uptake rate is not ideal, and the effect of dyeing dark colors is very poor, and basically cannot be used for dyeing dark colors. Therefore, it is necessary to develop cationic modifiers with higher performance to improve Dye uptake rate of dyes, improvement of soaping fastness of dyed fibers and fabrics, important theoretical and practical significance

Abstract

The invention relates to the fields of textile chemistry and dyeing and finishing engineering, and especially relates to a novel cationic modifier, a preparation method thereof, and a cotton fiber using the modifier. The modifier comprises, by volume, 100 parts of water, 5 parts of ammonia water with the mass concentration being 25%, 15 parts of an aqueous formaldehyde solution with the mass concentration being 40%, 27 parts of an aqueous dimethylamine solution with the mass concentration being 33%, 21 parts of epichlorohydrin and an aqueous solution of ammonium aminotrimethylene tris(N,N-dimethyl)tetrakis(2,3-epoxypropyl)chloride (XF) prepared through adding 0.5 g of tetrabutylammonium bromide as a phase transfer catalyst into per 100 ml of the water. The modifier can realize multi-time flame retardation, and endows the cotton fiber with a good dyeing property.

Description

technical field [0001] The invention relates to the fields of textile chemistry and dyeing and finishing engineering, in particular to a novel cationic modifier, a preparation method and cotton fibers using the modifier. Background technique [0002] Cotton fabric has good moisture absorption, breathability, warmth retention, antistatic and other properties. It is one of the most widely used fibers in natural fibers. It is mainly used in the field of clothing, and is also used in the preparation of sofa fabrics, curtain fabrics, other decorative fabrics and bedding. [0003] Traditional cotton fabric dyeing is mainly dyed with direct dyes, and the soaping fastness of the dyed cotton fabric is low. Therefore, in recent years, in order to improve the soaping fastness of cotton fabrics, reactive dyes are generally used for dyeing. Reactive dyes can chemically react with cotton fabrics and graft on fabrics with covalent bonds, so the soaping fastness is relatively high. Howe...
