Abstract

The invention belongs to the technical field of textiles, and particularly relates to a preparation method of a light energy self-disinfection formaldehyde-free and non-ironing fabric. The fabric is firstly padded with a formaldehyde-free and non-ironing finishing agent, then padded with a light energy self-disinfection auxiliary agent and baked to obtain the light energy self-disinfection formaldehyde-free and non-ironing fabric, wherein the formaldehyde-free and non-ironing finishing agent comprises formaldehyde-free and non-ironing resin and a catalyst, and the light energy self-disinfection auxiliary agent is an amino acid zinc phthalocyanine compound. Aiming at the problems that a traditional antibacterial and non-ironing fabric is poor in antibacterial property, not washable, high in formaldehyde content and the like in the use process, the functional fabric with the formaldehyde-free and non-ironing property and the antibacterial property is prepared, the antibacterial property and non-ironing property of the fabric are improved, and meanwhile, the risk of formaldehyde release of the conventional non-ironing fabric is avoided.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a method for preparing light-energy self-sterilizing formaldehyde-free non-ironing fabrics. Background technique [0002] Cotton fabrics are hygroscopic, breathable, and comfortable to wear, and are deeply loved by people. However, cotton fabrics have a large specific surface area and strong moisture absorption capacity, and are easily attached by microorganisms. The growth and reproduction of microorganisms on textiles not only affects the cleanliness of textiles, but also the wearability. Comfort, but also because of the reproduction of microorganisms, the cotton fiber will be discolored or damaged, produce a special smell, and even cause the spread of diseases, affecting the health of users. In order to reduce the invasion of bacteria on the human body, it is very necessary to carry out waterproof and antibacterial finishing on cotton fabrics. [0003] Common ant...
