Non-Cellulosic Polysaccharides from Cotton Fibre Are Differently Impacted by Textile Processing

Abstract

Cotton fibre is mainly composed of cellulose, although non-cellulosic polysaccharides play key roles during fibre development and are still present in the harvested fibre. This study aimed at determining the fate of non-cellulosic polysaccharides during cotton textile processing. We analyzed non-cellulosic cotton fibre polysaccharides during different steps of cotton textile processing using GC-MS, HPLC and comprehensive microarray polymer profiling to obtain monosaccharide and polysaccharide amounts and linkage compositions. Additionally, in situ detection was used to obtain information on polysaccharide localization and accessibility. We show that pectic and hemicellulosic polysaccharide levels decrease during cotton textile processing and that some processing steps have more impact than others. Pectins and arabinose-containing polysaccharides are strongly impacted by the chemical treatments, with most being removed during bleaching and scouring. However, some forms of pectin are more resistant than others. Xylan and xyloglucan are affected in later processing steps and to a lesser extent, whereas callose showed a strong resistance to the chemical processing steps. This study shows that non-cellulosic polysaccharides are differently impacted by the treatments used in cotton textile processing with some hemicelluloses and callose being resistant to these harsh treatments.

Heteromannan and Heteroxylan Cell Wall Polysaccharides Display Different Dynamics During the Elongation and Secondary Cell Wall Deposition Phases of Cotton Fiber Cell Development

“…Monosaccharide derivatization and partial methylation were carried out as described in Runavot et al (2014) . Cellulose, being a very resistant polysaccharide, is only partly analyzed by the methods used in this study; this particularly affects the results for older days post-anthesis.…”

Glycan Arrays: From Basic Biochemical Research to Bioanalytical and Biomedical Applications

“…Applications of potential commercial interest include the tracking of polysaccharide fates during grape ripening and fermentation (147,148). Investigations into the stability of noncellulose compounds during textile processing of cotton fiber showed that Arabinoxylan: major polysaccharide component of plant cell walls some polysaccharides are largely unaffected and might be used for functionalization procedures for the final cotton product (149). However, CoMPP is restricted by our limited knowledge of mAb epitopes: A change of polysaccharide composition can be detected, but the alterations on the molecular level remain unclear.…”

Preparation and characterization of cotton fiber fragments from model textile waste via mechanical milling and enzyme degradation

“…Typical raw cotton contains 94% cellulose (McCall and Jurgens 1951). Scouring and bleaching remove the non-cellulosic materials to the extent that processed cotton is almost pure cellulose, however, trace amounts of certain hemicelluloses and callose are still detectable (Runavot et al 2014). During chemical recycling, cotton is converted into regenerated or solvent spun cellulosic bers, such as rayon or lyocell, respectively.…”
