Effect of plasma treatment on the structure and allied textile properties of mulberry silk

Abstract

SynopsisStudies on the effect of nitrogen plasma on morphology and textile properties of mulberry silk fibers and fabrics have been conducted. The changes in the morphological structure have been monitored by transmission electron microscopy, X-ray diffraction, and internal reflection infrared spectroscopy. The changes in some of textile properties such as wettability, drying rate, and crease recovery owing to plasma treatment have also been investigated. It has been found that the surface of mulberry silk gets etched away, even affecting the crystalline region.This behavior is opposite to our findings on tassar'silk. Therefore, a n explanation of this differential behavior of mulberry with tasar on the basis of amino acid linkages vis-a-vis bonding, wettability, drying rate, and water retention capacity has been-attempted. These results have been used to arrive at an understanding of internal structure of mulberry.

Nanoscale surface roughening of mulberry silk by monochromatic VUV excimer lamp

“…As the change on exposure to excimer irradiation is restricted only to the surface of the fiber, the decrease in crystallinity is probably on account of decrease in the surface crystallinity. Similar results have also been reported by Nadiger and Bhat 16 when they treated mulberry silk with plasma.…”

Effect of plasma treatment on surface of protein fabrics

“…Part of the macromolecules on the surface and in the inner part of silk fibers being in the ion field oxidized during air plasma treatment. So the crystalline part became looser and crystallinity slightly decreased [22]. The same results were found in wool fabrics, which are shown in figure 6c &d. The X-ray diffraction patterns of untreated and air plasma treated wool were similar and that there was a broad peak at 2 =21.43° and 21.41 respectively, which were approximately the same.…”

“…Figure 7b &8b, shows surface roughness, which is used to increase wettability, printability, dyeability and adhesion properties of the fabrics. Many researchers have published their work on this aspect [22]. …”
