Abstract

The invention discloses a fiber deeper emulsion, which includes (according to weight): 20-40% vinyl monomer, 0.2-4% hydroxyl silicone oil, 0.001-2% reactive functional monomer, 0.5-5% emulsifier, 0.05-1% initiator, 50-80% de-ionized water and is prepared by a semi-continuous seeding emulsion polymerization technology. The invention is characterized in that the particle size of the fiber deeper emulsion is small, the amount of the emulsifier used is small, and the reaction process is easy to control and not to pollute the environment. The fiber fabric processed by the deeper emulsion has the advantages of deep color, wash durability, bearing dry cleaning, inhibiting whitening and smooth feeling, etc.

Description

technical field [0001] The invention relates to a fiber darkening agent emulsion and a preparation method thereof, belonging to the field of textile auxiliaries. Background technique [0002] Synthetic fibers have been widely used in recent years because of their high strength and mass production. Among them, polyester fiber is often used to replace natural fibers such as silk due to its cost advantage. [0003] Fiber products such as clothes are often required to have a high-quality sense of color depth as high-value-added products. But for polyester fiber, it is difficult to achieve the desired color depth through dyeing. Because polyester fiber (refractive index 1.71) has a unique specular luster, compared with natural fibers such as silk (refractive index 1.58) dyed with the same dye, when light hits the surface of polyester fiber, a large amount of incident light Reflected on the surface of the fiber, only part of the light is refracted into the fiber and absorbed by...
