Problems solved by technology

[0002] Commonly used UV absorbers include salicylic acid, benzophenones, benzotriazoles and triazine compounds, but there are many shortcomings in the application of cotton fabrics for UV protection dyeing and finishing, such as can only be used as additive anti-UV The production of ultraviolet fiber, but can not be used for the post-finishing of fabric, dyeing efficiency is low, the problem that dyeing efficiency is low and dyeing stability is unsatisfactory is serious, and the fabric color that the existing triazine compound cotton fabric dyeing method dyes is relatively poor. The anti-ultraviolet function is easy to fade, the anti-ultraviolet protection effect is not uniform, and the dyeing stability is poor. Therefore, the existing ultraviolet cotton fabric dyeing methods have insufficient dyeing, poor uniformity, low dyeing efficiency and poor dyeing stability. Ideal problem, so that the anti-ultraviolet cotton fabric cannot achieve better anti-ultraviolet effect

Abstract

The invention discloses an ultraviolet-proof cotton fabric dyeing method with high stability. An existing ultraviolet-proof cotton fabric dyeing method is improved. The ultraviolet-proof cotton fabricdyeing method comprises the steps of firstly soaking woven fabric in an ultraviolet-proof finishing agent, and simultaneously carrying out stirring and ultrasonic oscillation treatment, so that the ultraviolet-proof finishing agent is rapidly and uniformly dispersed on the woven fabric for dip dyeing for a proper time; then adding a dyeing auxiliary agent for ultrasonic oscillation treatment, andperforming sufficient impregnation, so that the active group of the ultraviolet-proof finishing agent can be more sufficiently chemically reacted with the hydroxyl group of the cotton fiber under thefinishing process condition; therefore, the ultraviolet-proof finishing agent is firmly combined with the cotton fiber, so that the finished cotton fabric keeps excellent ultraviolet-proof stability,the dyeing efficiency, the dyeing uniformity and the dyeing stability are improved, the cotton fabric can keep a good ultraviolet-proof function in the long-term use process and the washing process,and the cotton fabric prepared through the method has a good ultraviolet-proof effect.
