Textile fibers scanning electron microscopy

Graft and block copolymers of cotton cellulose, in fiber, yam, and fabric forms, were prepared by free-radical initiated copolymerization reactions of vinyl monomers with cellulose. The properties of the fibrous cellulose-polyvinyl copolymers were evaluated by solubility, ESR, and infrared spectroscopy, light, electron, and scanning electron microscopy, fractional separation, thermal analysis, and physical properties, including textile properties. Generally, the textile properties of the fibrous copolymers were improved as compared with the properties of cotton products.

Studying the Cause and Type of Fiber Damage in Textile Materials by Scanning Electron Microscopy... 

Pseudomorphs on a bronze Shang Dynasty halberd (ca. 1300 b.c.) were subjected to mineralogical analysis to determine their structure and composition. X-Ray diffraction, scanning electron microscopy, and energy dispersive analysis of x-rays were used in these analyses. Photomicrographs of pseudomorphs also were studied for fiber, yam, and fabric formations that give evidence of textiles. A model describing the process of silk pseudomorph formation was proposed.

Reports of textiles recovered from marine sites are uncommon. Wool and flax fibers from the Mary Rose and the Wasa have been identified employing optical and scanning electron microscopy (/5). The fiber content of the sails of the Wasa were identified as "vegetable but the method for fiber identification was not described 14). Morris and Seifert (75) describe treatment of textiles from the Defence with oxalic acid but do not indicate how they identified the linen, hemp, and silk fibers that they report are present. Conservation treatment of a silk cocade from the Michault was described 16). 

In an attempt to document the effect of the deep ocean environment on textile materials, modem materials were immersed at the site on the ocean floor for subsequent retrieval. While one set of samples was recovered after a three month period, additional samples have remained on the ocean floor since 1991 and are yet to be retrieved. The morphology of cellulosic fibers immersed for a three-month period has been investigated (S), The physical and chemical structure of dyed and undyed cotton fibers from the site compared with those of modem cotton and of cotton immersed on the ocean floor for three months were reported (70,77). Results of preliminary analyses on silk fibers using differential scanning calorimetry, energy dispersive x-ray spectoscopy, and scanning electron microscopy, have been reported (72).
