Abstract

Abstract 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.

Highlights

The wetlace nonwoven fabric was formed by wet-laid and spunlace reinforcement process [1, 2]
Characterization of the Ag Nps and prepared wetlace nonwoven fabric was performed in virtue of transmission electron microscope (TEM), UV-vis, X-ray diffraction (XRD), inductively coupled plasma atomic emission spectroscopy (ICP-AES), FESEM, Energy Dispersive Spectromete (EDS) mapping and antibacterial test
The antimicrobial activity of silver-treated fabrics was tested against E. coli and S. aureu by using a shaking flask method according to GB/T 20944.3-2008 (China). 0.75 g sample fabric, cut into small pieces in a size around 0.5×0.5 cm2, was dipped into a flask containing 70 ml of 0.3 mM PBS culture solution with a cell concentration of 1×105 cfu/ml-4×105 cfu/ml

Summary

Introduction

The wetlace nonwoven fabric was formed by wet-laid and spunlace reinforcement process [1, 2]. 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]. Surface coating of biomedical fibers with Ag NPs has been extensively studied in term of the utility in biomedical field [11,12,13,14,15,16,17]. Wood pulp/viscose fibers were chosen to produce the wetlace nonwoven fabric. For improving the antibacterial activity of fabric, HSDA was used to prepare Ag NPs to be fixed on the surface of wetlace nonwoven fabric
