Abstract

The invention relates to a color-deepening finishing agent for dyed polyester textiles. Nano-titanium dioxide particles serving as solids and an amino modified polyorganosiloxane microemulsion serving as a film-forming material are compounded to form the color-deepening finishing agent for the polyester textiles. Due to the small grain size effect and the large specific surface area of the nanoparticles, the contact of the nanoparticles with fibers is increased and a relatively high adsorption rate can be formed; due to the flexibility and the film-forming property of the organic silicon junction fragment of the film-forming material covering the nanoparticles, the color-deepening finishing agent is capable of forming an uneven thin film capable of generating scattering reflection on the surface of the treated fabric, and consequently, the absorptive amount of the fabric to the incident light can be greatly increased, the reflected light can be reduced and the effect of enhancing the color depth of the fabric can be achieved. The dyed polyester textiles treated by use of the color-deepening finishing agent are deepened in color under the circumstance that the inherent characteristics of the dyed fiber products are not damaged; besides, the treated dyed polyester textiles have good color fastness and also have antibacterial property.

Description

technical field [0001] The invention belongs to the field of textile dyeing and finishing auxiliaries, in particular to a darkening finishing agent for dyeing polyester fabrics. Background technique [0002] As a traditional pillar industry of our country, the textile industry is widely used in industry, agriculture, aquatic products, medicine, national defense industry, etc., and plays a great role in promoting the development of the national economy. Synthetic fibers have been widely used in recent years because they are strong and can be mass-produced. Especially polyester fiber (that is, polyester), has the advantages of high strength, good elasticity, good dimensional stability, and wear resistance. Durable, it is a variety of synthetic fiber textiles with many varieties, large output and fast development. However, since there are basically no active groups in the polyester structure, there are few dyeing positions, high crystallinity, tight fiber structure, and smoot...
