Abstract

The invention belongs to the technical field of functional fabrics, and particularly relates to a composite structure comprising a fabric layer and a spherical activated carbon layer and a preparationmethod thereof. The composite structure comprising the fabric layer and the spherical activated carbon layer is characterized in that the surface of the fabric layer facing spherical activated carbonis provided with a depression extending from the surface to the inside of the fabric layer; at least part of the outer surface of the spherical activated carbon is bonded to at least part of the inner surface of the depression. By adopting the composite structure, clogging of fabric and difficulty in breathing of skin caused by excessive adhesives can be avoided, and the human body comfort is improved remarkably. Moreover, the composite structure can significantly improve the bonding area of the fabric and the activated carbon, and greatly improve the washing fastness of protective clothing.Moreover, the preparation method of the composite structure and clothing is convenient, and has a broad prospect for large-scale production.

Description

technical field [0001] The invention belongs to the technical field of functional fabrics, in particular to a composite structure comprising a fabric layer and a spherical activated carbon layer and a preparation method thereof. Background technique [0002] With the development of the chemical industry, many highly toxic chemicals have emerged, and the current chemical industry uses a large amount of highly dangerous chemicals. During the production, storage and handling of these toxic chemicals, people's lives will be endangered due to leakage or accidents. In addition, people also face the threat of chemical weapons, biological weapons and terrorism. In 1995, the Japanese cult organization "Akumo Shinrikyo" released sarin gas in the Tokyo subway, which was the first time in human history that chemical warfare agents were used to launch terrorist attacks against civilians. In 2001, the anthrax mail terrorist incident in the United States shocked the world. In the event ...
