The effect of quarantine-level gamma irradiation on cotton fiber and its subsequent textile processing performance

Abstract

Quarantine treatments of raw cotton fiber with gamma irradiation are known to have an adverse effect on fiber properties and thus could have an effect on processing into textile products. In this study, the effects of such irradiation treatments on two different cottons, cultivars of Upland and Extra Long Staple, were studied. Even at low dosages, gamma irradiation affects the physical properties of the fiber, with these effects becoming more apparent and significant as the dosage increased. While the affect on moisture regain was marginal, dye affinity was adversely affected. From a textile processing performance and quality point of view, the irradiation dosages did not have a significant impact on the yarn evenness and imperfection values, but did have a significant effect on yarn strength and elongation, as well as fabric strength and abrasion resistance. The degradation of these properties could have a significant to catastrophic effect on product durability.

Potential effects of ionizing radiation on the evidentiary value of DNA, latent fingerprints, hair, and fibers: A comprehensive review and new results

“…Takács et al [78] ascribed observed increasing absorbance in the spectral regions that are representative of OÀ ÀH stretching [88] to increased intermolecular hydrogen bonding at the expense of intramolecular hydrogen bridges. Molecular degradation is further supported by reports of radiation-induced depolymerization and lower molecular weight [78,81,83] and decreased paracrystalline regularity [81,82]. For neutron exposure of cotton, onset of fibrillation has been reported at a dose of 10 11 neutrons cm À2 [89].…”

“…Beginning at 25 kGy gamma irradiation, and steadily increasing with dose, there were significant changes in the FTIR absorbance spectra of cotton-cellulose fibers, with a notable increase in the characteristic carbonyl region, 1730-1750 cm À1 [78]. Contrastingly, Van der Sluijs and Church [81] saw no change in FTIR carbonyl absorbance with 74 kGy gamma. Takács et al [78] ascribed observed increasing absorbance in the spectral regions that are representative of OÀ ÀH stretching [88] to increased intermolecular hydrogen bonding at the expense of intramolecular hydrogen bridges.…”

“…Depolymerization and oxidation of cotton-cellulose begins at a 15 kGy gamma dose [78]. Weakening of natural fibers begins to be noticeable above 15 kGy gamma, increasing progressively with dose [79][80][81]. Surface damage of cotton fibers, including cracks attributed to loss of interfibrillar bonding, was reported after a gamma dose of 100 kGy, becoming more severe with increasing dose [78,81,82].…”

In terms of mechanical properties, however, the effects of gamma irradiation of 25 and 50 kGy on cotton product durability "may be somewhere between significant and catastrophic" [81,p.…”

Synthesis of 2-methylacrylamide/high-molecular-weight Cellulose for Removing Anionic Dyes from Water by Irradiation with Gamma Rays

“…Recently, cellulosic biomass has been irradiated with 60 Co gamma rays to modify its physicochemical properties and extend its usefulness (Le Moigne et al 2017;Misra et al 2020). The physicochemical properties of the irradiated materials differ greatly from those of the virgin cellulosic biomass (Sluijs and Church, 2013;Le Moigne et al 2017). Various functional groups have been grafted onto the molecular chains of cellulose via irradiation to promote its mechanical, optical, and antibacterial properties (Tataru et al 2020;Söylemez et al 2018; Barsbay and Güven, 2019).…”
