At the same time silk thread simply increases in size, and good air circulation promotes rapid evaporation of excessive moisture. So silk fabric absorbs perspiration while letting the skin breathe.

What fabric absorbs water best?

Moisture Absorbing Fabrics

The most common absorbent fibre used is cotton, but other fabrics have recently been designed that are more absorbent, such as modal, micro-modal, Tencel®, and other viscose-based fibres. All of these are made from the same base material – plant cellulose – which loves water.

Does silk deteriorate?

However, silk is susceptible to ageing, and the preservation of such artefacts is of significant concern. The deterioration of silk causes embrittlement of the textile leading to splits and tears, and eventually a powdery and very friable fabric.
