Flame-retardant treatment method for wool fibers

Abstract

The invention relates to a flame-retardant treatment method for wool fibers. The flame-retardant treatment method includes aiming at flammability of the wool fibers, microwave irradiating the wool fibers in the microwave reactor, impregnating the postirradiation wool fibers into carbon-ball suspension made of deionized water, gamma-mercaptopropyl triethoxysilane and nitric acid modified carbon balls serving as a flame retardant, and performing flame-retardant treatment in a supersonic disperser. The flame-retardant treatment method is short in process procedure and accurate and real in data, the wool fibers are flame-retardant and fine in resistance to washing, the limit oxygen index of the wool fibers after being washed for 30 times is 34%, and the flame retardancy of the wool fibers can be improved by 36%. Besides, the flame-retardant treatment method for the wool fibers is high in efficiency.

Description

technical field [0001] The invention relates to a flame retardant treatment method of wool fiber, which belongs to the technical field of the flame retardant method of wool fiber and its application. Background technique [0002] Wool is one of the earliest natural fibers used by humans in textiles. It is soft and elastic, with naturally formed wavy curls. The high nitrogen content in the chemical structure of wool fiber has certain flame retardant properties, but it still cannot meet the needs of some high-efficiency flame retardant products, and it is easy to cause fires and cause great harm to the human body. Therefore, wool fibers must be treated efficiently. Flame retardant treatment can ensure personal safety and expand the use range of wool fiber. [0003] At present, the flame retardant treatment technology of wool fiber is relatively backward, and it is difficult to meet the flame retardant needs of high-grade wool products. 25.4%, failed to meet the flame retarda...

[0002] Wool is one of the earliest natural fibers used by humans in textiles. It is soft and elastic, with naturally formed wavy curls. The high nitrogen content in the chemical structure of wool fiber has certain flame retardant properties, but it still cannot meet the needs of some high-efficiency flame retardant products, and it is easy to cause fires and cause great harm to the human body. Therefore, wool fibers must be treated efficiently. Flame retardant treatment can ensure personal safety and expand the use range of wool fiber

[0003] At present, the flame retardant treatment technology of wool fiber is relatively backward, and it is difficult to meet the flame retardant needs of high-grade wool products. 25.4%, failed to meet the flame retardant standard; some use copolymerization to improve the flame retardant performance of wool fiber, but to achieve a higher flame retardant effect requires a large amount of flame retardant, which greatly increases the production cost; some use sol to The wool fiber is treated with flame retardant, but the washing resistance becomes poor, and the permanent flame retardant effect cannot be achieved
