Hydrophilic fibre
WebBiologically, the human hair is a complex fibre with various morphological components. Hair essentially consists of keratin, a fibrous structural protein, which is a member of the superfamily of intermediate filament proteins, containing 18% cysteine as calculated from the overall amino acid composition. 19,20 The hair fibre is divided into three main … WebIn terms of particle retention, filters fall into two categories: surface filters and depth filters. Surface filters, generally referred to as membranes, trap particles exclusively on the top surface. These filters are well suited to samples with low particulate content. However, high particulate content tends to rapidly clog the filter surface.

Webby the rate at which moisture can diffuse into and out of the fibres, due to the lower moisture diffusivity of the textile material [2]. In the case of hydrophilic fibre assemblies, vapour diffusion does not obey Fick’s law. It is governed by a non-Fickian, anomalous diffusion [12,13]. This is a two stage diffusion process.
