Effect of rf cold plasmas on polysaccharides

Biopolymer-based Stimuli-Responsive Polymeric Systems for Functional Finishing of Textiles

“…Depending on the nature of the plasma gas used, different modification is expected. Ward et al (1978) reported that air, nitrogen and argon as plasma gases produce cotton surface with physical and chemical characteristics that differ significantly from untreated cotton. These three most commonly used plasma gases (air, nitrogen and argon) have been used for the activation of cotton surface ).…”

Modification of Cotton by Radiofrequency Plasma of Ammonia

“…Pavlath and Slater [9] found that exposure of wool to low-temperature plasmas increased strength and abrasion resistance while reducing felting shrinkage. We have previously reported [7,13,14] studies of the effect of rf plasmas of argon, nitrogen, or I air on a group of polysaccharides that in~luded cotton and purified cellulose. This report concerns the effects of ammonia cold plasma on cotton printcloth.…”

“…Low-temperature, low-pressure plasmas are especially suited for modification of natural polymers [7,9,10,[12][13][14]. These &dquo;cold&dquo; plasmas are generated by gaseous electric discharge, provide a source of highenergy electrons without excessive heating, and are highly reactive chemically.…”

Effects of plasma treatment and metal‐ion chelation on lightfastness of dyed polyester/cotton fabric

“…Earlier work in this laboratory has been carried out for imparting soil resistance by plasma treatment. 8 The action of plasma is confined only to the surface regions without penetrating the bulk 9,10 ; hence in the present investigation, an attempt was made to study the effect of plasma modification and chelation of dye with metal ions on the lightfastness. The sample (polyester/cotton blend) was entered in a dye bath (material to liquor ratio 1:50) containing dye for a 2% shade.…”
