Functionalisation of textiles by inorganic sol–gel coatings

Abstract

The maintenance and improvement of current properties and the creation of new material properties are the most important reasons for the functionalisation of textiles. The coating of textiles with chemically or physically modified silica sols with particle diameters smaller than 50 nm (''nanosols'') enables the manifold alteration of their physico-mechanical, optical, electrical and biological properties. Thus the protection of textiles against destruction and the creation of new advantageous functions can be realised. Prospective new products to be developed include textiles with water, oil and soil repellency and with antimicrobial properties. This article discusses recent results from applying modified silica nanosols to the functionalisation of textiles.

Antibacterial Modification of Textiles Using Nanotechnology

“…This antibacterial activity was measured by washing the samples several times after sol-gel treatment. Mahltig et al,'s (2005) results exhibited that antimicrobial durability of the treated samples increased with increase in water glass content [49]. For the samples without water glass, bacterial reduction % was zero only after 10 washing cycles.…”

“…As a consequence of their importance, the number of different antimicrobial agents suitable for textile application on the market has increased dramatically. These antimicrobial agents differ in their chemical structure, effectiveness, method of application, and influence on people and the environment as well as cost [8][9][10][11][12]. In the literature [9,10,12], there are several different classifications of antimicrobial agents according to efficiency, mechanism of antimicrobial activity and washing resistance.…”

Kajian Aktivitas Antibakteri Kain Tercelup Komposit Kitosan-Silika

“…Namun, penggunaan kitosan sebagai bahan antibakteri pada tekstil memiliki ketahanan yang kurang memuaskan terhadap proses pencucian (Mahltig et al, 2005). Oleh karena itu, ditambahkan silika pada larutan kitosan untuk meningkatkan stabilitas kitosan pada kain.…”

Silan/biopolymer microgels for functionalization of cotton fabric: dual responsive pH and temperature and antibacterial properties

“…This improving is due to chemical reactions between epoxy ring of GPTMS and hydroxyl groups on the cotton surface. (Abidi et al, 2007;Mahltig et al, 2005;Mohamed et al, 2014;Park et al, 1999;Schramm et al, 2004) Stimuli-responsive hydrogels are response hydrogels to external environment such as solvent composition, temperature, light, pH, mechanical force and magnetic or electrical field (Bonina et al, 2004;Guo et al, 2007;Mohamed et al, 2016;Roy et al, 2010;Santos et al, 2010;Suwa et al, 1998). Temperature and pH-responsive hydrogels have been studied more than others.…”
