Smelly-removing white carbon powder with high whiteness and method for producing the same and use thereof

Abstract

The present invention provides a high whiteness deodorant white charcoal powder and a manufacturing method and application thereof. A mesoporous material powder with a high whiteness and a large pore space is used as a mesoporous mother plate. The outer layer of the mesoporous mother plate is covered by a thin uniform macromolecule film, and then a surface-carbonized macromolecule film layer is formed by high temperature carbonization. Since the carbonized macromolecule thin film layer is comparatively thin, the excessive reduction of the whiteness of the mother plate can be avoided, and the high porosity white nanometer powder with a carbon layer surface is formed, which is distinguished as the white charcoal powder. White charcoal fibres are manufactured by putting the white charcoal powder into the fusion spinning process of fibrous raw material. The whiteness of the conventional carbon fibres can be largely improved, while the carbon layer on the surface can maintain the functionality of the conventional carbon fibres, such as far infrared ray and deodorization, etc. The material characteristics of the large pore space mesoporous material enable the white charcoal fibres to maintain most of the functional effects after a dyeing program. The color variation characteristic of the white charcoal fibres and yarns is largely improved by the enhancement of the whiteness. The white charcoal fibres and yarns are better in the color application than that of the conventional carbon fibres.

Description

technical field [0001] The invention relates to a method for manufacturing white carbon powder, in particular to a method for manufacturing deodorizing white carbon powder. Background technique [0002] Traditional carbon-containing fibers are mainly made by grinding carbon blocks into powder, adding them in the spinning process or coating the fiber surface with a binder; in order to maintain the functional properties of the fibers such as far-infrared rays and deodorization, the addition rate must reach a certain level. However, regardless of the addition rate, the addition of carbon to the fiber will reduce the whiteness of the finished fiber, that is, black gray, and then the processing and dyeing will also affect the original function, making the application of carbon fiber greatly reduced; [0003] For another example, generally, the carbon powder is directly added to the fiber raw material and drawn into fiber filaments, and the combination of the carbon powder and the...

Problems solved by technology

[0007] However, the current carbon fiber-containing method is to use the carbon powder after miniaturization, continue to use the existing fiber technology, and make the carbon powder in the form of an additive; due to the low whiteness of the carbon powder, the If the mixing of carbon powder and fiber raw materials is uneven, color difference is likely to occur. Although it can be improved by adding dispersants and dyeing, in order to maintain the original characteristics of carbon materials such as far infrared rays and odor absorption, it is necessary to add The content of bamboo charcoal powder in the fiber cannot be reduced, so the space for improving the whiteness after treatment is quite limited;
