A wound dressing containing a multi-ply knit fabric, where the fabric contains a first and a second knit ply. The first knit ply contains a plurality of first yarns and forms the upper surface of the fabric. The second knit ply contains a plurality of polytetrafluoroethylene (PTFE) yarns, where the PTFE yarns have a transmission in the IR region of 8-10 μm at least about 40%, and a thermal conductivity of at least about 0.2 W/(m.Math.K) forms the lower surface of the fabric. The first ply and the second ply are integrated through combined portions formed by interlacing first yarns among the PTFE yarns of the second knit ply, interlacing PTFE yarns among the first yarns of the first knit ply, or interlacing a plurality of third yarns among the first yarns and the PTFE. The multi-ply knit fabric also contains a composition containing at least one silver ion-containing compound.

Provided is a water-absorbent resin which is capable of giving an absorbent material improved gel-shape stability and which has excellent water-absorption capacity. A water-absorbent resin of the present invention is a polymer of a water-soluble ethylenically unsaturated monomer, and has the following properties (1) and (2): (1) A disintegration amount at 20-fold swelling is 30% by mass or less; and (2) a solubility in physiological saline is 25% by mass or less. (Determination Method for Disintegration Amount at 20-Fold Swelling) 5 g of the water-absorbent resin is added to 100 g of physiological saline to allow the water-absorbent resin to absorb the physiological saline, thereby obtaining a gel. The obtained gel is divided approximately equally into five portions, and these portions are introduced respectively into cylindrical molds having a length of 3.6 cm and a radius of 2.8 cm and molded. The masses of the five molded cylindrical gels are measured. The heaviest and the lightest of the five gels are removed, and the remaining three gels are used as samples. A mass Wa (g) of each sample is measured. Each weighed sample is placed on the uppermost sieve of a combination of JIS standard sieves having a mesh size of 5.6 mm and a receptacle in this order and shaken for 10 minutes using a Ro-Tap shaker (rotation speed, 290 rpm; number of taps, 165 rpm). A mass Wb (g) of the gel which has passed through the sieves is measured. The disintegration amount of each sample is calculated using the following equation: Disintegration amount of sample (%)=Wb (g)/Wa (g)×100. An average of the disintegration amounts for three samples to be measured is regarded as the disintegration amount at 20-fold swelling of the water-absorbent resin.
