“…Even cotton, which is often projected to dry slower than synthetics, has drying rates close to those of the polyester fibres, as observed from Table 1. These observations are consistent with the results of drying of porous solids (Pan & Zhong, 2006) as well as specific results on fabrics (Steele, 1958b). Established theories relate the early part of drying to evaporation of water from a pool of water at the interphase of fabric and atmosphere, which at high water contents would be maintained irrespective of the substrate.…”

“…In case of higher saturation levels, which correspond to constant-rate periods of drying, the drying rates do not change with water concentration. This is happening due to reasons described previously (Steele, 1958b). At the lower saturation levels, on the other hand, which corresponds to falling-rate period of drying, a clear trend of increased drying rate at higher water concentration is observed.…”

“…In recent works, extent to which rate of fabric drying might depend upon, the following factors are examined: (a) fiber moisture regain, and (b) speed of capillary migration (Haghi, 2004). However, equations for drying rates in constant-rate and falling-rate periods of drying are defined in earlier work (Steele, 1958a).…”

Gravimetric absorption test system (GATS) is used to measure the absorption capacity, absorption rate and drying rate of knit hoses, prepared from different fibres. The fibres studied are cotton, polyester and variety of modified polyesters. The study has shown that desorption or drying rate is at least two orders of magnitude lower than absorption rate. This finding implies that drying is the limiting process in moisture management. Further experiments on knit fabrics made from polyester and cotton, show that the drying rates are independent of fibre type in the constant-rate period, while the drying rates in the falling-rate period are dependent on fibre type. Subsequently, it is shown on the polyester fabric that drying rate in the falling-rate period depends on water concentration. Based on this understanding, an approach for enhancing drying rate in the falling-rate period is defined. The approach is demonstrated on knit hoses prepared from cotton and polyester yarns in alternating stripe form. The drying rate in the falling-rate period is found to be higher in the polyester-cotton stripe knit hose. A hypothesis for the observed enhancement in drying rate by wicking is put forth in terms of the internal movement of water from polyester to cotton portion. Experimentally, it is shown that 16% improvement in drying time is achieved in the case of the polyester-cotton stripe samples. Further, indications of internal water movement from polyester to cotton portion have been obtained by tracking the surface temperatures of the knit hoses during drying by infrared (IR) thermography.

“…The current investigation was not intended solely as a basic study of spreading via the capillaries in a textile assembly, but also as a practical investigation into the behavior of water solutions of reagents commonly employed in low wet pickup finishing of cotton-containing textiles via lick roller. Data in the area are lacking since much of the early research into spreading and sorption into textiles was aimed at imparting water resistance or fast drying properties to fabrics rather than enhancing spreading and penetration [1,18].…”

Incomplete spreading and penetration of durable press reagents during low pickup finishing of cotton textiles result in poor distribution of reagent residues, which adversely affects textile performance. To assess those properties of fabric and solution that affect spreading and penetration, drop absorbancy time (DAT), vertical wicking distance (VWD), and saturation value (SV) were determined. The solution-holding capacity of the fibers in the fabrics was assessed via solution of imbibition (SI). The durable press reagent systems studied contained DMDHEU, MgCl 2 · 6H 2 O, and the wetting agent Silagen MA alone and in combination. The fabrics included a series of all-cotton Osnaburg-type fabrics, in which the fill thread count was increased incrementally, and a series of intimate blend sheetings with a range of cotton/ polyester ratios. Enhanced spreading, as indicated by decreasing DAT and SV and increasing VWD, was associated with increasing fill thread count in the all-cotton Osnaburgs, decreasing cotton content in the blend sheetings, and the inclusion of the wetting agent Silagen MA in the test liquor. Depressed spreading was associated with increasing solids concentration, which increases solution viscosity, and with inclusion of the MgCl 2 · 6H 2 O catalyst. The SI of the fabric was increased by increasing the cotton content and by increasing the DMDHEU content of the liquor. The latter is attributed to an increase in solution density.Low wet pickup techniques for applying durable press reagents to cotton fabrics consume less energy ' One of the facilities of the Southern Region, Agricultural

“…Today's trend for searching alternative renewable and biodegradable fibre sources has attracted considerable interest in hemp as eco-friendly and healthy fibres [24]. Acrylic yarn was chosen for combining with the hemp one due to a low moisture regain of acrylic fibres (1.5 -2.5 %) [25] and fast drying ability [26]. There are other synthetic fibres with the ability to dry faster than acrylic ones, but acrylic fibres were confirmed to offer some good comfort performance to textile materials due to their porosity, softness and good liquid management properties [27][28].…”

Liquid transport in textile fabrics determines thermal comfort during high physical activity of a person when liquid perspiration is produced and needs to be transferred away from the skin to keep the thermal balance. In this investigation, an attempt was made to get some indications of how the combination of the fabric composition, geometry and dimensional stability, and the moisture content influences liquid transfer properties of plain weft knitted fabrics. Therefore, the knitted fabrics made from pure hydrophilic (hemp fibres), pure hydrophobic (acrylic fibres) and a hydrophilic/hydrophobic (hemp/acrylic) fibre blend underwent a trial wear and care period. The Malden Mills water distribution test was performed for the knitted fabrics with different moisture contents (0-30 %) in order to evaluate the effect on liquid transfer properties. Water transfer ability and water holding capacity of the knitted fabrics were also determined after undergoing the wear trial test. The obtained results were analysed with respect to macro and micro scales of porosity of knitted fabrics. It has been shown that the geometric configuration of the complex porous network in knitted fabrics influenced their liquid transfer properties in the whole moisture content range regardless of the composition. Despite the reconfiguration of the pore system in the knits during the trial period, their liquid transfer properties were still dependent on the pore size and distribution.
