Balancing the decomposable behavior and wet tensile mechanical property of cellulose-based wet wipe substrates by the aqueous adhesive

Abstract

With the current global outbreak of novel coronaviruses, the fabrication of decomposable wet wipe with sufficient wet strength to meet daily use is promising but still challenging, especially when renewable cellulose was employed. In this work, a decomposable cellulose-based wet wipe substrate is demonstrated by introducing a synthetic N-vinyl pyrrolidone-glycidyl methacrylate (NVP-GMA) adhesive on the cellulose surface. Experimental results reveal that the NVP-GMA adhesive not only significantly facilitates the chemical bonding between cellulose fibers in the wet state, but also increase the surface wettability and water retention. The as-fabricated cellulose-based wet wipe substrate displays a superb water retention capacity of 1.9 times, an excellent water absorption capacity (completely wetted with 0° water contact angle), and a perfect wet tensile index of 3.32 N.m.g −1 . It is far better than state-of-the-art wet toilet wipe on the market (non-woven). The prepared renewable and degradable cellulose-based substrate with excellent mechanical strength has potential application prospects in diverse commercially available products such as sanitary and medical wet wipes.

Preparation of cellulose-based wipes treated with antimicrobial and antiviral silver nanoparticles as novel effective high-performance coronavirus fighter

“…With the recent outbreak of COVID-19 pandemic worldwide, the fear of infection has increased dramatically, and therefore the demands for medical nonwoven masks and disinfection wipes have rapidly increased too [ 1 ]. The severity of coronavirus infection can cause pneumonia, sever acute respiratory syndrome (SARS), and even can leads to death.…”

“…So, this pandemic had resulted in a crucial socio-economic impact globally [ 2 ]. It was stated that in 2019, the global medical nonwovens market value will reach 1.28 billion dollars and will continue to grow at an annual rate of 1.28 billion dollars and will continue to grow at annual rate of 4.6% and it is estimated to reach a market size of 1.61 size of billion dollars by 2024 [ 1 ]. Disinfection wipes known also as pre-impregnated disinfecting wipes, they are widely used for various applications particularly in critical areas in hospitals and healthcare centers for the decontamination of medical devices and high-touch environmental surfaces due to their effective performance [ 3 ].…”

Study of Antimicrobial Potency of Synthesized Cellulose-Based Nanocomposite Films Incorporating Bi-Fe-Sn Trimetallic Microcrystalline Using Terminalia arjuna Leaf Extract for Packaging and Medicinal Applications

“…Potential outcomes of this work indicated that cellulose based thin flms can be a suitable alternative for plastic packaging if processed further [60]. Along with that, they can be used in herbal medicine related to skin diseases due to their antimicrobial efcacy, as wet wipes [61], edible packaging [62], and wound healing tendency [47], because they are obtained from natural resources [63], such as fruit peels [64], leaves [65,66], and biodegradable in nature [67]. So, they can have various potential applications in various healthcare systems [68], energy storage devices [69], and wastewater treatment [70].…”

Enhancing Cross-Linking Network for Superior Wet Strength of Paper by Sustainable Hyperbranched Polyimines

“…22,23 In order to address the aforementioned challenges, researchers have made significant efforts to find alternatives to traditional wet strength resin PAE. Both synthetic 24 and natural polymers 9 with linear or less branched structures have been developed as wet strength agents. Synthetic wet strength agents, primarily polymer-based, include polyacrylamide and polyethylenimine.…”
