The influence of conventional and plasma treatments on the handle and related properties of fabrics

Research output: ThesisDoctoral Thesis

Abstract

This study has investigated the handle and related properties affected by the aqueous conventional finishing and plasma treatment of cotton and wool fabrics, and the influence of plasma treatment in conventional finishing processes.
Fabric handle depends not only on the process condition, but also on the condition of the material input. Both the pre-finishing and post-finishing processes changed fabric mechanical properties and handle. Not only do the finishing agents categorized as hand modifiers (external finishes) caused changes in the mechanical properties and handle of fabrics, the internal fabric modifiers could also modify the fabric mechanical properties and made changes in fabric handle.
Apart from conventional finishing which affected fabric mechanical properties, LTP (Low Temperature Plasma) treatment also could modify fabric surface, in turn it affected the treated fabric mechanical properties. Plasma modification caused changes of the treated fabric surface both morphologically and chemically. The results on the scourability and dyability revealed that LTP treatment has increased the scouring and dyeing rate of wool and cotton fabrics. A shorter time may be chosen in scouring and dyeing, the process was more environmental friendly and it reduced energy consumption by needing less time to reach the desirable state of dyeing and scouring. The study of LTP treatment on fabric mechanical properties and handle indicates that choosing a shorter scouring and dyeing processing time by using plasma pre-treatment on conventional fabric scouring and dyeing will obtain the desirable effect of scouring and dyeing, and this will not affect the finished fabric total hand value.
The mechanical properties most sensitive to fabric handle are outlined as well. Among all the mechanical parameters, the high correlation among the mechanical properties and fabric handle to various finishing processes was analyzed, and it is exhibited by bending and shear properties.
The research work also indicates that material properties are affected by fabric processing and particularly by the finishing processes. It is suggested that we may be able to engineer desirable handle attributes in fabrics now that we know more about the effect of properly finishing relationship.
