“…Textiles coated with sol-gel are reported to impart many important properties, as shown in Figure 10. Antimicrobial finishing of cotton textile based on water glass by sol-gel method was investigated by [48]. They prepared the silica sol by acidifying water glass solution with 0.05M H2SO4 solution to pH 11.…”

“…Selanjutnya dilakukan proses pengeringan atau dry untuk menguapkan air dan pelarut sehingga terjadi kondensasi dan membentuk gel. Proses pengeringan selanjutnya yaitu proses cure bertujuan untuk memantapkan lapis tipis yang terbentuk pada kain karena pada tahap tersebut terjadi proses kondensasi lanjutan sehingga akan terbentuk jaringan polimer pada kain (crosslinking) yang telah bebas dari air dan pelarut (Xing et al, 2007) Data pada Tabel 1 tersebut menunjukkan proses pelapisan yang dilakukan menghasilkan persentase wet pick-up (berat basah setelah pencelupan) kain komposit kitosan-silika 0,01 M untuk variasi pencelupan 5 kali sebesar 127,14%, 10 kali sebesar 130,59%, 15 kali sebesar 132,41%, dan 30 kali sebesar 134,57%. Hasil tersebut menunjukkan bahwa semakin banyak proses pencelupan kain pada larutan komposit kitosan-silika maka kemungkinan komposit kitosan-silika yang terserap pada kain akan semakin banyak pula.…”

ABSTRAKTelah dilakukan penelitian tentang pengaruh jumlah proses pencelupan kain menggunakan komposit kitosan-silika terhadap aktvitas antibakteri kain kitosan-silika. Proses pelapisan kitosan-silika pada kain dilakukan dengan metode pencelupan atau dipcoating dengan teknik pengeringan pad-dry-cure pada temperatur dry 80 o C dan temperatur curing 140 o C. Uji aktivitas antibakteri kain kitosan-silika terhadap bakteri S.aureus dilakukan dengan metode Shake flask turbidimetry. Hasil penelitian menunjukkan adanya pengaruh jumlah proses pencelupan kain dalam larutan kitosan-silika terhadap persentase aktivitas antibakterinya. Persentase aktivitas antibakteri setelah 24 jam pada kain tercelup komposit kitosan-silika dengan variasi pencelupan 5 kali adalah sebesar 18,52%, kain dengan 10 kali pencelupan adalah sebesar 22,06%, kain dengan 15 kali pencelupan adalah sebesar 32,87% dan dengan variasi pencelupan sebanyak 30 kali diperoleh persentase aktivitas antibakteri sebesar 39,32%.

The chitosan-silica composites were deposited on cotton fabrics using pad-dry-cure method in dip-coating process with drying temperatureof of 80 o C and curing temperature 140 o C . Antibacterial activity of chitosan-silica coated cotton fabrics were evaluated against S.aureus using shake flask turbidimetry. The result showed that the number of chitosan-silica coating processes on fabric influenced its antibacterial activity. Antibacterial activity of chitosan-silica coated fabrics was 18,52% with fifth coating traetment numbers, 22,06% with tenth coating traetment numbers, 32,87% with fifteenth coating traetment numbers and 39,32% with thirtieth coating traetment numbers.

“…Such a property is shown by silicone-organic coatings made of a sol synthesized from vinyltriethoxysilane by the sol-gel method. Moreover, such coatings constitute matrices to which one can durably incorporate inorganic or organic functional particles with specified properties and in this way obtain expected functionalization of textile fabrics, such as bioactivity, [1][2][3][4][5][6] water resistance, [7][8][9] barrier property against UV radiation, 10,11 optimized performance durability-resistance to abrasion or pilling formation. [12][13][14][15][16] The basic condition of the application of a thin coating based on SiO 2 , made by the sol-gel method for various so-called nano-coating finishes of textile fabrics, is its stable adhesion to the surface of fiber/fabric.…”

This paper presents the effect of pretreatment of polyamide (PA6) nonwoven with corona discharge on the stability of the adhesion of thin hydrophobic silicone-organic coating based on vinyltriethoxysilane, made by the sol-gel method. This pretreatment with corona discharge causes a change in the physicochemical properties of the PA6 fiber surface. These changes include, among others, an increase in the fiber surface roughness, wettability, and surface free energy. At the same time, XPS and EDS investigations have shown an increase in the degree of oxidation and the formation of functional polar groups on the fiber surface (C-O-, C-OH, and O=C-O-). As a result of the changes in the surface properties of pretreated PA6 fibers, a higher degree of the sol deposition was obtained compared with that for untreated nonwoven surface. The assessment of the stability of the adhesion of thin hydrophobic coating to the fiber surface was carried out on the basis of changes in the content of silica deposited on fibers and the kinetics of water contact angle after washing and abrasion processes. In the end, the PA6 nonwoven, pretreated with corona discharge, shows a higher stability of the adherence of the thin silicone-organic coating and a higher degree of hydrophobicity than the untreated nonwoven.
