Polyester fabric is treated with DCDMS solution by two methods: dipping the fabric directly in DCDMS solution for different
intervals and dipping the fabric in DCDMS solution after its exposure into RF plasma chamber for different durations at optimized
exposure power conditions. The physical properties of polyester fabric treated with DCDMS in the presence or absence of air
plasma have been compared with control fabric. Different characterization techniques like scanning electron microscope, attenuated
total reflectance-IR and Dataflash 100 colour measurement spectrophotometer are used to assess the surface morphology, composition
and change in colour parameters. Water repellency property of both untreated and modified polyester fabric is studied using
AATCC test method 39 (1971). The effectiveness of the water repellency property of modified polyester fabric is checked by
repeated washing up to ten cycles.

The preparation of PDMS microemulsions was carried out by adding at controlled rate dichlorodimethylsilane (DCMS) in a solution of sodium dodecylpolyoxyethylene(8) sulphate. The instantaneous hydrolysis of DCMS and subsequent condensation of the corresponding dihydroxysilane generate dispersions of cyclosiloxanes of small lengths (4 to 6 D units). The high load of chloride ions released during the hydrolysis step requires the presence of the above-mentioned electrosteric surfactant to avoid rapid coagulation of the dispersion. In addition, its sulphate end-group captures a proton that catalyses the ring-opening polymerization of cyclosiloxane as well as the polycondensation of disilanol PDMS chains. Final particles exhibit a diameter of about 50 nm for a polydispersity index of less than 1.1. They are constituted of PDMS chains exclusively linear (

Cotton fabric was treated with dichlorodimethylsilane (DCDMS) solution by two methods. In the first method, the fabrics were
directly dipped into DCDMS solution for different time intervals and in the second method, the fabric was first subjected
to radiofrequency (RF) plasma treatment for different durations and optimized exposure power condition and then immersed in
DCDMS solution. The physical properties of cotton fabrics, treated with DCDMS in the presence/absence of air plasma have been
compared with those of the control fabrics. Changes in the surface morphology structure and composition were observed through
scanning electron microscopy and attenuated total reflectance-IR. The change in colour parameters of the fabric due to the
treatment was assessed by Dataflash 100 colour measurement spectrophotometer with colourtools QC 1.3 colour quality software.
The water repellent property of untreated and modified fabrics was studied using AATCC test method 39 (1971). The effectiveness
of the water repellent property was checked by washing the treated fabrics up to ten cycles.
