Abstract

A reactive fiber, a method of manufacturing the reactive fiber, and an outer shell of chemical, biological and radiological (CBR) protective clothing including the reactive fiber are provided. The reactive fiber includes a fiber, a plurality of reactive projections formed on a surface of the fiber, and a plurality of hydrophobic projections formed on the fiber and surfaces of the reactive projections.

First claim

What is claimed is:

1. A reactive fiber comprising:
a fiber;
a plurality of reactive projections formed on a surface of the fiber; and
a plurality of hydrophobic projections formed on the fiber and surfaces of the reactive projections,
wherein each of the hydrophobic projections has a diameter of 5 nm to 10 μm,
wherein the hydrophobic projections are hydrophobic, and
wherein each of the hydrophobic projections comprises a compound including Al particles to which a hydrocarbon or alkyl group is attached.

2. The reactive fiber of claim 1 , wherein each of the reactive projections has a diameter of 100 nanometers (nm) to 100 micrometers (μm).

3. The reactive fiber of claim 1 , wherein a distance between the reactive projections is in a range of 10 nm to 10 μm.

4. The reactive fiber of claim 1 , wherein the fiber comprises at least one selected from the group consisting of cotton, polyester, polyethylene terephthalate and rayon.

5. The reactive fiber of claim 1 , wherein the reactive projections have decomposition reactivity of at least one selected from the group consisting of a nerve agent, a blister agent, an industrial toxic substance and a toxic gas.

6. The reactive fiber of claim 1 , wherein each of the reactive projections comprises at least one selected from the group consisting of a metal oxide, a metal hydroxide and a metal-organic complex.

7. The reactive fiber of claim 1 , wherein each of the reactive projections comprises at least one selected from the group consisting of Zr(OH) 4 , ZrO, MOF-808, UiO-66-NH 2 , TiO 2 and Mg(OH) 2 .

8. The reactive fiber of claim 2 , wherein a distance between the reactive projections is in a range of 10 nm to 10 μm.

9. The reactive fiber of claim 1 , wherein each of the hydrophobic projections comprises a compound including Al particles to which a hydrocarbon group is attached.

10. The reactive fiber of claim 1 , wherein each of the hydrophobic projections comprises a compound including Al particles to which an alkyl group is attached.

11. An outer shell of chemical, biological and radiological (CBR) protective clothing, the outer shell being woven from the reactive fiber of claim 1 .

12. Chemical, biological and radiological (CBR) protective clothing comprising the outer shell of claim 11 .
