In recent years, new technologies for microcapsules in the field of textiles have emerged, such as microcapsule fabric softeners and detergents; thermochromic dyes using microcapsules, photochromic dyes can be used to make color-changing fabrics and sensor fibers; Special microcapsules for high-tech smart textiles such as self-cleaning and self-healing materials.
The core of microcapsule dyeing technology is to make the microcapsules as the core material. When dyeing, the dye microcapsules can be directly put into the dyebath, and the dyes are dyed, dyed and the difference in the concentration of the dyes in the dyebath, so that the dyes are continuously released, adsorbed and Dye the fibers and finish the dyeing.
General microcapsule finishing includes the softness, wrinkle resistance, water and oil repellent finishing of the fabric. At present, many softeners, anti-wrinkle finishing agents, water- and oil-repellent finishing agents are mostly emulsifiers, and the dispersion stability is not high. It is often caused by the addition of other components to break or precipitate, and if they are made into microcapsules It can improve the dispersion stability and the compatibility of each component, and improve the finishing effect.
The microcapsule aroma finishing of the fabric is to use the fragrance as the core of the capsule, and the core material is isolated from the external environment, so that its properties are basically unchanged. At the beginning, the fragrance of the outer layer of the microcapsules is fragrant. During the wearing process, due to the external force such as friction and heat, the fragrance inside the microcapsule slowly releases the fragrance, which has a long-lasting effect, so that the textile has considerable Long lasting aroma. Chuanhua Zhilian has launched a silky towel.
A color-changing textile refers to a textile that exhibits different colors depending on external stimuli (such as light, heat, electricity, magnetism, etc.). The color-changing materials used in textiles are mainly photochromic and thermochromic materials. The micro-encapsulation treatment of the reversible thermo- or photochromic compound is carried out, and the photochromic microcapsules are arranged on the fabric by padding and coating methods, thereby realizing the light and heat stimulation of the fabric. Inverted color.
