Problems solved by technology

[0003] The technical problem to be solved by the present invention is to aim at the disadvantages that current acrylic fabrics are easy to generate static electricity, the light fastness of cationic fluorescent dyes commonly used in fluorescent dyeing is not good, and the fiber itself has poor anti-ultraviolet performance and antibacterial performance. The acrylic fiber is modified to improve its antistatic performance, and the modified acrylic fiber is treated in the same bath by anionic acid fluorescent yellow dye, natural cationic dye berberine and anionic ultraviolet absorber, so that the acrylic fiber fabric can obtain good fluorescence performance, antistatic performance, antistatic UV properties, antimicrobial properties and high light fastness

Abstract

The invention discloses a fluorescein dyeing and multifunctional finishing method for acrylic fabric. The fluorescein dyeing and multifunctional finishing method includes the steps that acrylic is modified, and the modified acrylic is treated with acid fluorescein dye, natural cationic dye berberine and an anionic ultraviolet absorbent. According to the fluorescein dyeing and multifunctional finishing method, as the acrylic is modified, cationic groups are given, anionic groups of the acrylic are also retained, the acid fluorescein dye and the anionic ultraviolet absorbent can be combined with the cationic groups of the acrylic, and the natural cationic dye can be combined with the anionic groups of the acrylic. According to the method, the prepared acrylic fabric has static resistance, bacterium resistance, ultraviolet resistance and the fluorescence performance, and the light fastness of the acrylic fabric is also improved.

Description

technical field [0001] The invention belongs to the technical field of dyeing and finishing, and relates to a one-bath treatment method for dyeing and finishing modified acrylic fibers by using fluorescent dyes, natural dyes and ultraviolet absorbers, especially capable of realizing antibacterial, anti-ultraviolet, fluorescent dyeing and improving daily life of acrylic fiber fabrics. Light fastness. Background technique [0002] Acrylic fabric has become one of the main choices of textile fabrics because of its good warmth retention and bulkiness, and its price and cost advantages. Due to the disadvantages of poor UV performance and antibacterial performance, how to develop fluorescent dyes with antistatic, anti-ultraviolet and antibacterial functions and excellent light fastness is the goal pursued by dyeing and finishing workers. At present, if acrylic fabrics want to realize the above functions, they need to carry out various processing, the process flow is long, and it ...
