“…Therefore, the net effect of softening agent on wool fibres is an initial decrease in fabric stiffness and improvement in the handle of the treated fabrics. The results of a subjective evaluation of the effects of fabric softness and harshness were consistent with the bending stiffness evaluation (Naebe et al, 2011b). The mechanism for the reduction in prickliness of silicone-treated fabrics appears to be reduced fibre-fibre friction rather than a modification in fibre modulus (Naylor, Veitch, Mayfield, & Kettlewell, 1992).…”

“…The existing knowledge on the effect of silicone polymer on the surface of the wool fabrics confirms a reduction of both bending modulus (Kim & Kang, 2002) and friction coefficient (Kim & Kang, 2002;Naylor, Phillips, Veitch, Dolling, & Marland, 1997) of wool fibres. Earlier work has shown that the plasma treatment resulted in a higher bending modulus (Kan & Yuen, 2009;Naebe et al, 2011b) and a higher friction coefficient (Kim & Kang, 2002;Thomas, 2007) on wool fabrics compared with UT fabrics.…”

“…It is also possible that the lower WCM values occurring after silicone treatment are a result of less fibre on the fabric surface interacting with the recording head of the WCM. It has been known for many years that the application of silicone polymers can glue protruding fibres together or cause them to adhere to the surface of the yarn and therefore not protrude (figure 1, Makinson, 1975;Naebe et al, 2011b).…”

“…Previous studies (Kim & Kang, 2002;Naebe, Cookson, Denning, & Wang, 2011b) have shown that plasma treatment increased the stiffness of the fabric with increasing treatment time and plasma power. Handle evaluation of treated fabrics has shown that plasma treatment made the fabric harsher and longer plasma treatment times resulted in a serious impairment of fabric handle.…”

The comfort properties of the pique and single jersey knitted wool fabrics were investigated using the Wool ComfortMeter (WCM). The fabrics were knitted in three cover factors and treated with either plasma or a silicone softening agent and were compared with untreated fabrics. Plasma treatment did not show significant effects on the comfort value. However, silicone polymer significantly reduced WCM values suggesting that the silicone coating reduced the number of protruding fibres on the fabric surface. Regardless of treatment used, pique fabrics showed a lower WCM value, and therefore were perceived to be more comfortable than the single jersey structure. While the effect of cover factor was not significant, in fitted model to predict the WCM value of fabrics, mass/unit area and fabric thickness were significant predictors along with fabric structure and finishing treatment.

“…Vertical wicking test results shown in Table 1 are consistent with the drop test results. An earlier study [30] found that exposure of a similar fabric to helium plasma for just 1 second was sufficient to make the wool surface hydrophilic. It was established that this was primarily due to surface modification only and did not involve removal of the fatty acid layer.…”

Plasma treatment is an emerging surface modification technique that alters dye uptake of wool without using chemicals or water for pre-treatment. Padding is an established continuous dyeing technique known for its efficient use of water, time and energy. This study combined these two techniques for colouration of wool fabric using two natural dyes derived from the Acacia plant family. The investigation focused on the effects of plasma treatment and obtaining unique patterning effects. Helium (100%) and a mixture of helium and nitrogen (95%/5%) were used as the plasma gases under atmospheric conditions. Plasma treated wool fabric was padded with the above natural dyes. Copper sulphate and ferrous sulphate were applied on the dyed fabric as mordant yielding neutral shades of beige and grey respectively. Up to a 30% enhancement of dye adsorption on plasma treated wool substrate was observed as compared to untreated sample for both gases used. This higher adsorption indicates the hydrophilic character of the natural dyes used. Key performance parameters such as fastness to washing, rubbing and light were tested and found to be satisfactory. A single process tone-on-tone pattern was achieved by controlling the plasma exposure of treated area. This study concluded that a merger of natural dyes with modern plasma treatment and padding techniques for wool colouration was feasible.
