Abstract

The invention relates to a black inorganic fiber and a plasma preparation method thereof, and particularly discloses a black inorganic fiber. The black inorganic fiber comprises a fiber matrix and carbonized sugar attached to the fiber matrix, wherein the fiber matrix is an inorganic fiber capable of tolerating heat at the temperature of 500 DEG C, such as a basalt fiber, a ceramic fiber, a quartzfiber and a sepiolite fiber. The carbonized sugar attached to the fiber matrix is obtained by the following method: 1) pretreatment: carrying out surface modification on the fiber matrix by using wetplasma to obtain activated fibers, and soaking the activated fibers in a sugar aqueous solution under the action of tension; and 2) carbonization dyeing: carbonizing the soaked fibers obtained in thestep (1) at a high temperature to obtain the inorganic fibers with carbonized sugar attached to the fiber matrix after dyeing. The black inorganic fiber is novel and unique, simple in preparation method, environment-friendly and pollution-free.

Description

technical field

[0001] The invention belongs to the field of fiber materials, and in particular relates to a black inorganic fiber and a plasma preparation method thereof. Background technique

[0002] As we all know, fiber post-treatment dyeing is a common dyeing method. In particular, plasma technology is used to treat fibers to increase fiber surface roughness and chemically active groups, so that dyes are more easily adsorbed to the fiber surface. Chinese patent documents 200810059897.X and 201811577679.5 both disclose related methods for dyeing aramid fiber using inert gas plasma, and achieved good results.

[0003] However, unlike organic fibers such as aramid fibers, inorganic fibers have a denser structure and stronger surface inertness. Existing technologies often fail to achieve excellent results, and there are few reports on dyeing methods for such inorganic fibers. In recent years, inorganic fibers represented by basalt fibers have developed rapidly. If basalt ...
