Abstract

In the present work, sheets of Papyrus ( L.), manufactured by lamination from strips pre-treated with different treatments, were evaluated for their technological and fungal infestation properties ( AFl375, Ani245 and Cgl311). The results showed that the highest values of tensile strength, tear strength, burst index and double-fold number were observed in papyrus sheets produced from strips treated with nano-cellulose (0.25%), dimethyl sulfoxide (DMSO 10%), Tylose (0.25%) and nano-cellulose (0.5%), with values of 98.90 N·m/g, 2343.67 mN·m²/g, 1162 kpa·m²/g and 8.33, respectively. The percentage of brightness ranged from 49.7% (strips treated with KOH 2% + 100 mL NaClO) to 9.6% (strips treated with bark extract 2%), while the percentage of darkness ranged from 99.86% (strips treated with leaf extract 2% or bark extract 0.5%) to 67.26% (strips treated with NaOH (2%) + 100 mL NaClO). From the SEM examination, sheets produced from treated strips with extracts from and or showed no growths of and . Additionally, other pre-treatments, such as Nano-cellulose+Tylose 0.5% (1:1 /) and Tylose 0.5%, were also found to have no growth of . In conclusion, strips pre-treated with nanomaterials and extracts were enhanced in terms of the technological and antifungal properties of produced Papyrus sheets, respectively.

摘要

在本研究中，对通过层压由经过不同处理的纸条制成的纸莎草纸（L.）片材的工艺性能和真菌侵染特性（AFl375、Ani245和Cgl311）进行了评估。结果表明，在用纳米纤维素（0.25%）、二甲基亚砜（DMSO 10%）、泰勒（0.25%）和纳米纤维素（0.5%）处理的纸条制成的纸莎草纸片中，观察到拉伸强度、撕裂强度、破裂指数和双折次数的最高值，分别为98.90 N·m/g、2343.67 mN·m²/g、1162 kpa·m²/g和8.33。亮度百分比范围为49.7%（用2% KOH + 100 mL NaClO处理的纸条）至9.6%（用2%树皮提取物处理的纸条），而暗度百分比范围为99.86%（用2%叶提取物或0.5%树皮提取物处理的纸条）至67.26%（用2% NaOH + 100 mL NaClO处理的纸条）。通过扫描电子显微镜检查，用[具体植物]提取物处理的纸条制成的片材未显示出[具体真菌]的生长。此外，还发现其他预处理，如纳米纤维素+泰勒0.5%（1:1 /）和泰勒0.5%，也没有[具体真菌]的生长。总之，用纳米材料和提取物预处理的纸条分别在制成的纸莎草纸片的工艺性能和抗真菌性能方面得到了增强。
