Abstract

The invention discloses a surface treatment method for a flatting agent for a chinlon chemical fiber. The method comprises the following steps of: performing ultrafine smashing treatment on a TiO2 raw material to obtain ultrafine TiO2 powder of which the particle diameter is distributed in the range of 100-400 nanometers; precipitating an inorganic film by adopting a precipitation method to precipitate a layer of amorphous TiO2 on the surface of the TiO2; and modifying the surface of the TiO2 by adopting a coupling agent method to enable amorphous TiO2 which is rich in hydroxyl and has a large specific surface area and a titanic acid ester coupling agent to form more chemical bonds. The finally obtained TiO2 digestant has the characteristics of small particle diameter, high flatting property, high color fastness to light, and high weather resistance color fastness, and high dispersivity, high compatibility and high stability in fibers.

Description

technical field [0001] The invention relates to a surface treatment method, in particular to a surface treatment method of a matting agent for nylon chemical fiber. Background technique [0002] In the production of synthetic fibers, under the premise of not affecting the strength and tensile properties of the fibers, in order to improve the wearability of the fibers, obtain an opacity similar to that of natural fibers, and obtain bright colors after printing and dyeing, it is usually necessary to follow a certain standard in synthetic fibers. The ratio of adding matting agent. In synthetic fibers, TiO is usually selected 2 The powder is used as a matting agent. TiO 2 Powder is an inorganic compound whose molecular formula is TiO 2 , Its advantages are: abundant sources, stable properties, a large difference in refractive index from chemical fibers, and excellent extinction effect. At present, anatase-type titanium oxide is mostly used as a matting agent, mainly because...
