“…Hasil penelitian Du [3] (2008) menunjukkan bahwa kompleks Ag nanopartikel kitosan dapat menghambat pertumbuhan bakteria Escherichia coli 25922, Salmonella choleraesuis ATCC 50020 dan Staphylococcus aureus 25923 dengan konsentrasi hambat minumum 9 ppm Zhilong [4] melaporkan bahwa hasil uji anti bakteri nanopartikel kitosan dan nanokuaternari kitosan dalam polimetil metakrilat, menunjukkan bahwa daya hambat nanoquaternari kitosan terhadap pertumbuhan S.aureus dan S.epidermidi lebih besar dibanding dengan nanopartikel kitosan. Niamsa et al [5] menambahkan nanopartikel MPEG-b-PDLL untuk meningkatkan daya anti bakteri, kekuatan tarik, dan sensitifiti terhadap kelembaban pada film yang mengandungi kitosan dan silk fibroin.…”

AbstrakDalam upaya menghasilkan warna kain sutera yang tahan luntur terhadap gosokan serta kuat dan tahan terhadap bakteri, dilakukan suatu penelitian untuk membuat kain sutera berwarna yang tahan gosok dan tahan luntur. Kain sutera yang tahan warna dan tidak luntur, dihasilkan melalui pelapisan permukaan kain dengan menggunakan nanopartikel kitosan. Nanopartikel kitosan yang dibuat melalui reaksi ikatan silang gugus amina (-NH 2 + ) pada kitosan dengan gugus phosphat ( -PO 4 ) -3 dari sodium tripolophosphat (STPP). Kain sutera sebelum dilapis , ditreatmen terlebih dahulu melalui proses degumming dan asilasi. Proses degumming bertujuan untukmenghilangkan serisin agar dihasilkan kain sutera yang lembut, berkilau sementara asilasi berfungsi sebagai jembatan antara kitosann dengan kain sutera. Sebagai pewarna digunakan ekstrak Henna. Hasil uji terhadap ketahanan dan kelunturan warna menunjukkan bahwa kain sutera yang diasilasi dan dilapis dengan nanopartikel kitosan mempunyaio ketahanann dan kelunturan warna yang lebih baik dibandingkan dengan Kata kunci : nanopartikel kitosan, kain sutera, pelapisan, ketahanan dan kelunturan

“…Deposits are observed (via SEM), which are attributed to the modifying agents (Arai et al 2001). Acylation provides an enhanced surface for the grafting of chitosan to wool or silk to provide antibacterial and anti-felting properties and superior dyeing ability in an environmentally friendly fashion (Davarpanah et al 2009; Ranjbar-Mohammadi et al 2010).…”

“…Acylation agents include dodecenylsuccinic anhydride and ctadecenylsuccinic anhydride, anhydrides such as succinic anhydride and phthalic anhydride, and solvents including dimethyl sulfoxide and dimethylformamide (Arai et al 2001;Davarpanah et al 2009). Wool is noted to gain more weight and acyl content than silk.…”

“…Low-temperature RF plasma treatment of silk fabrics with chitosan is advantageous over the wet chemical treatment process because of the following reasons: 1) The only required chemicals for grafting are chitosan, acetic acid and NaOH, making this process highly environmentally-friendly compared to the chemical grafting process which requires anhydrides and solvent such as DMSO or DMF [8]; 2) Because only environmentally-friendly chemicals are used, when fabrics reach their end of life, there will be no chemical discharged to the environment; 3) Because plasma treatment is a closed system, byproducts (if any) can be trapped rather than being released to the environment; 4) The process is worker-friendly [18]; 5) Plasma treatment alters only the skin of the fabric without affecting bulk properties, while for the chemical process, chemicals used may affect bulk properties; 6) Although the initial investment for plasma equipment and high vacuum system can be high, the long-term saving from not using chemicals can eventually outweigh the initial investment.…”

“…To increase antibacterial ability for surface enhancement, silk fiber surface was modified using anhydrides (succinic anhydride and phthalic anhydride) in different solvents (dimethyl sulfoxide (DMSO) and N,N-dimethyl formamide (DMF)) to chemically graft chitosan [8]. Grafted fibers were expected to exhibit an antibacterial property due to the presence of chitosan on the surface.…”

Abstract. A 13.56 MHz RF plasma discharge was successfully utilized to activate and coat Thai silk fabrics with chitosan for durable antibacterial property. Uncolored and untreated Thai silk fabrics were activated in Ar plasma for 5 minutes with an optimized RF power of 120 W under Ar pressure of 0.8 Torr. After plasma activation, specimens were submerged and stirred in a 1% (w/v) chitosan solution. FTIR analysis confirmed the presence of chitosan on the silk fabrics. From SEM analysis, chitosan was observed to coat silk fibers almost everywhere. RF plasma treated fabrics were able to absorb the chitosan solution substantially faster than those without the treatment. Another benefit of increased hydrophilicity is the ability of the treated fabrics to allow human perspiration to flow through more effectively, providing additional comfort when worn in tropical-zone countries. Antibacterial properties against E. coli and S. aureus reduced with increasing washing cycles dropping to approximately 95% after 5 rounds of washing. Extrapolation of linear trend lines revealed that for the case of E. coli, it will take approximately 16 washing cycles to reduce the antibacterial ability to 90%. For the case of S. aureus, it will take approximately 10 washing cycles to reduce the antibacterial ability to 90%. Fabrics without RF plasma treatment prior to chitosan solution submersion will have their antibacterial ability for E. coli and S. aureus reduced to 90% after only about 5 washing cycles. Thus, RF plasma treatment can effectively induce chitosan to provide a strong and durable coating for Thai silk fabrics, thus, offering a new, very environmentally-friendly coating technique for Thai silk with chitosan for potential use in the textile industry.
