“…The prepared Ag NPs solution was diluted with deionized water to keep the Ag content range from 50 to 200mg/L. To keep the gram weight of wetlace fabric around 60g/m 2 and the strength of the wetlace fabric around 10N, 7g wood pulp and viscose fibers (70/30 in weight) were immersed in Ag NPs solutions for 30min at a water tank which contained a 0.1m 2 net curtain with the bath ratio of 1:50 [1,2].…”

To prepare antibacterial fabrics with simple approach, wood pulp/viscose fibers and amino-capped silver nanoparticles (Ag NPs) solution were utilized to form Ag Nps-coated wetlace nonwove fabric. Characterization of the Ag Nps and prepared wetlace nonwoven fabric was performed in virtue of TEM, UV-vis, XRD, ICP-AES, FESEM, EDS mapping and antibacterial test. FESEM and EDS characterizations demonstrated the hierarchical and uniform coating of high-density Ag NPs on wood pulp fibers, and antibacterial test indicated the excellent antibacterial activity of prepared wetlace nonwoven fabric.

“…The wetlace nonwoven fabric was formed by wet-laid and spunlace reinforcement process [1,2]. Compared with traditional fabrics, wetlace nonwoven fabric exhibits high generation speed and possess sufficient softness, flexibility and conformability, making it widely applied in moist wipes and biomedical field [3][4][5][6].…”

“…The combination of wet-laid and hydroentanglement techniques offers possibilities to produce dispersible wipes with sufficient wet strength [11,12]. The wet-laid technique is similar to conventional papermaking processes, which uses stapled or chopped synthetic fibers (up to 35 mm), rather than pure pulp fibers.…”

Tensile Strength and Dispersibility of Pulp/Danufil Wet-Laid Hydroentangled Nonwovens

et al. 2019

Wet-laid hydroentangled nonwovens are widely used for disposable products, but these products generally do not have good dispersibility and can block sewage systems after being discarded into toilets. In this study, both pulp fibers and Danufil fibers are selected as we hypothesize that the high wet strength and striated surface of Danufil fibers would allow us to produce nonwovens with better dispersibility while having enough mechanical properties. The wet strength and dispersibility of nonwovens are systematically studied by investigating the influence of the fiber blend ratio, fiber length, and water jet pressure. The results indicate that the percent dispersion could be as high as 81.3% when the wet strength is higher than 4.8 N, which has been improved greatly comparing the percent dispersion of 67.6% reported before.

“…Currently, a growing number of disposable nonwovens are consumed, leading to almost 1,200,000 tons of discarded medical-hygiene nonwovens being produced from medical and household waste per year. 1 Among them, adhesives share around 25–30 wt.%. 1 However, the adhesives contained in disposable medical and hygiene nonwovens are mainly polyacrylate, polyvinyl acetate, polyvinyl alcohol, and butadiene-styrene copolymer latexes.…”

Biodegradable adhesives from nano-chitosan-reinforced unfolded soy protein have been fabricated to potentially reduce environmental pollution and drive a sustainable textile industry. The weak adhesion strength and poor water stability of soy protein films limit their use in the textile industry. In this work, the influence of sodium-dodecyl-sulfonate on unfolding of soy protein, and the reinforcement effects of nano-chitosan on the tensile properties of unfolded soy protein adhesives were investigated. The results demonstrate that the bio-adhesives developed had 157% and 85% increments on tensile strength and water stability compared with unmodified soy protein. Also, dry and wet strength of the pulp/viscose wet-laid nonwovens were increased 43% and over 100% after adhesion, indicating that modified soy protein shows promise for use as a textile bio-adhesive for sustainable industry.
