Problems solved by technology

However, the fibers of fluorescent dyes and nylon / ammonia blended fabrics are mainly combined by ionic bonds and van der Waals forces. Due to the weak bonding force, the color fastness is poor, and it is easy to fade, and often the wet fastness is poor.

Abstract

The invention relates to a method for improving the fluorescence dye color fastness of brocade / spandex blended fabrics, and belongs to the technical field of fabric printing and dyeing. The method for improving the fluorescence dye color fastness of brocade / spandex blended fabrics comprises the following steps: preprocessing the brocade / spandex blended fabrics by using mixed plasma including O2 and NH3 in a vacuum chamber; carrying out fluorescence dyeing treatment on the preprocessed brocade / spandex blended fabrics; and post-processing the fluorescence dyed brocade / spandex blended fabrics. The fluorescence dyeing method can substantially improve the dyeing effect of disperse fluorescence dyes in brocade, spandex and brocade / spandex blended fabrics, allows the dyes to be closely combined with the fabrics, and can substantially improve the water washability, the color fastness to rubbing and the color fastness to light of the brocade / spandex blended fabrics.

Description

technical field [0001] The invention relates to the technical field of fabric printing and dyeing, more specifically, the invention relates to a method for improving the dyeing fastness of fluorescent dyes of nylon / ammonia blended fabrics. Background technique [0002] Nylon, also known as polyamide fiber or nylon, has many amide groups in its molecular structure. Spandex is also called polyurethane fiber, and there are many carbamate groups in its molecular structure. Nylon / spandex blends have many excellent physical and mechanical properties and are widely used in the textile field, such as sportswear and professional clothing. Fluorescent dyes are often used on textiles such as traffic police and sanitation workers' professional attire, school uniforms, sportswear, shoes and hats for warning, decoration or aesthetic effect. The so-called fluorescent dye refers to a substance that absorbs a light wave of a certain wavelength and emits another wavelength greater than the ...
