Abstract

The problem to be solved by the invention is to provide an infrared-absorbing fibrous structure capable of realizing a quick-drying property without depending on a single filament cross-sectional shape of a fiber constituting a fibrous structure, and a garment comprising the same. The present invention is an infrared-absorbing fibrous structure formed by processing an infrared-absorbing fiber comprising infrared-absorbing material fine particles selected from tungsten oxide fine particles represented by a general formula WO<X> (W is tungsten, O is oxygen, 2.45 ≤ X ≤ 2.999) or composite tungsten oxide fine particles represented by a general formula M<Y>WO<Z> (element M is an element selected from Cs, Rb, K, Tl, In, etc., 0.001 ≤ Y ≤ 1.0, 2.2 ≤ Z ≤ 3.0) on a surface and/or in an interior thereof, characterized in that a particle size of the fine particles is 1 nm or more and 200 nm or less, and a content of the fine particles per unit area of the structure is 0.05 g/m<2> or more and 8.0 g/m<2> or less; the infrared-absorbing material fine particles having absorbed solar energy generate heat, whereby drying of moisture contained in the structure can be promoted.
