Characterization of the conventional and organic cotton fibres

Abstract

The characterization of the conventional and organic cotton fibres to understand the differences present between them is presented. The cotton fibres were characterized for their fibre properties such as the surface morphology, surface chemical composition, surface elemental composition and internal fibre structure. The results show that the surface morphology and surface chemical composition of both the cotton fibres are similar. The surface elemental composition of both the cotton fibres shows that organic cotton fibres have higher percentage of metals than the conventional cotton fibres. Based on the FTIR spectrum analysis, it is observed that the organic cotton fibres may have a higher proportion of representative groups compared to that of the conventional cotton fibres. The fraction of I α and I β cellulose shows that I β cellulose dominates in both cotton fibres. The crystallinity of both the cotton fibres was determined using the wide angle X-ray diffraction data. The results show that crystallinity of both fibres is similar.

Characterization of new cellulosic fiber derived from Lasia spinosa (L.) thwaites rhizome and its potential use as biodegradable textile material

“…Similar peaks are recorded in the literature for several natural fibers such as Bamboo, Hemp, Jute, and Kenaf fibers at 321 °C, 308.2 °C, 298.2 °C and 307.2 °C respectively [ 11 ]. The third stage of the TG spectrum indicates the degradation of wax and lignin in the fiber within the temperature range of 340 °C - 540 °C [ 11 , 48 ], and [ 5 ]. According to the FTIR analysis, it is found that the LS rhizome fiber consists of small quantities of lignin and waxes.…”

Type-effects of multiple waste-sourced biochar feedstocks on methylene blue adsorption

“…Similarly, the source of PKPB has a relatively large number of stomata, so the tissue is more fragmented, similar to CRPB, CMPB, CMNB and ALSB, showing broken flakes with unevenly attached particles (small fragments or larger inorganic salt particles) on its surface, showing limited channel space similar to biochar made from coconut coir, and its overall structural clarity was not obvious. 24 Therefore, waste-derived biochar has a clear and complete carbon skeleton structure and has uniform morphological distribution, which can be porous, fibrous or lamellar structures, all of which are favorable for adsorption. It is inferred that the different morphologies of biochar are not only due to microstructural differences between the various organs of various plants, 25 but also due to the external force on pyrolysis products caused by differences in the composition of bound water and volatile organic compounds in plant feedstocks.…”

Organic cotton network in Brazil addressing textile and clothing sector

“…A large number of literatures is available about cotton characterization and properties (MURUGESH et al, 2013). Nearly 90% of the cotton fibers are cellulose (Table 1).…”

“…When the presence of metals such as Fe, Ca, K, Al, Mg and P commonly found in cotton was analyzed, and the organic cotton fibers has higher percentage of metals than the conventional cotton fibers (except Ca). Based on MALDI-TOF (Matrix Assisted Laser Desorption/Ionization -Time of Flight) mass spectrum analysis, it is observed that surface chemical composition of the conventional and organic cotton fibers is similar (MURUGESH BABU et al, 2013).…”

“…As a more sustainable option, organic cotton is produced without the use of synthetically compounded chemicals and transgenic seeds and in the case of Brazil also without irrigation (MURUGESH et al, 2013). A system of production that seeks to maintain and replenish soil fertility and the ecological environment of the crop.…”
