“…Nowadays, the variety of green approaches have been carried out in developing the antimicrobial and antiviral cotton fabric. From the literature, the antimicrobial cotton clothes have been produced using plant leaves extract such as aloe vera ( Ali, Purwar, Joshi and Rajendran, 2014 ), Azadirachta indica (neem) ( El Aty., Bassyouni, Zaher and Guirguis, 2018 , Rajendran et al, 2012 ), lotus ( Oh and Na, 2014 ), ginger, and curry leaves ( Jaswal, Preet and Goal, 2017 ). Plant leaves extract has been chosen as a coating material because it is economical, eco-friendly and bioactive in nature with antifungal, antibacterial and anti-viral activity.at ( Guo X. and Mei, 2016 , Kawai et al, 1998 ).…”

The highly contagious nature of SARS-CoV-2 (COVID-19) virus has created a havoc effect all over the world in a very short period. The most effective method for precaution of this virus as suggested by WHO is use of PPEs (triple layered face mask, body suits) and social distancing. However, the frontline doctors and medical staff have high risk of exposure to the virus during treatments and removal and discarding of the PPEs. Also the PPEs are of the onetime use and wearing these PPEs in hot and humid seasons is very uncomfortable. A possible solution of this problem is if clothes are anti-bacterial and anti-viral in nature, one single-layered will be sufficient and the spread of virus will also be minimized. Considering this, we have designed a facile and durable anti-wash antimicrobial coating on cloth by aloe vera and hexadecyltrimethoxysilane (HDTMS). In lab scale study, present coating shows good chemical and thermal stability making it reusable multiple times even after repeated washing. The coated cloth reveals the excellent anti-dirt and stain resistance properties leading to complete non-adherence of dirt and stain (e.g. Color, food, ink) on it. Anti-bacterial and anti-fungi properties of the coated cloth were confirmed by doing E. coli (bacteria) and A. Niger (fungus) culture studies, respectively. This coating is imbibed with well-known anti-viral agent aloe vera which inhibits the attachment of the virus on the surface. The water-repellent nature of the coating combined with the use anti-viral agent, aloe vera makes it a potential anti-COVID-19 coating.

Nanomaterials play a vital role in textile industries due to their unique properties and applications. There is an increase in the use of nanoscale phyto products in textiles to control the bacterial infection in fabrics. Here, natural herbal nanoparticles of different sizes were prepared from shade-dried plant leaves using ball milling technique without any additives. The amorphous herbal nanoparticles possess an average particle size of 40 ± 2 nm and UV-absorption maximum at 269 nm. nanopowders-chitosan nanocomposites were prepared and coated on cotton fabrics using pad-dry cure method. The evaluation of antibacterial activity against (22.05 ± 0.06 mm) and (27.17 ± 0.02 mm), UV-protection properties (UV-protection factor = 57.2 ± 0.1), and superhydrophobic nature (155 ± 3°) of the prepared herbal nanoparticles and their composites were analysed by disc diffusion, UV-visible spectral analysis, and contact angle analysis. Understanding the functional properties of herbal nanoparticles, coated particles on fabrics highlights their potential applications in protective clothing with better antimicrobial properties, hydrophobicity, and UV-protection properties. This study of using herbal nanoparticles in textiles significantly enhances the fabric performance to develop protective textile fabrics in defence and biomedical fields.

“…Dari penelitian terdahulu, 13,[18][19] analisa FTIR kain kapas fiksasi kitosan menunjukkan puncakpuncak, yaitu pada bilangan gelombang 3300 -3500 cm -1 untuk gugus OHdan NH 2 , serta 1325 cm -1 juga untuk amina ; 1730 cm -1 lemah dari stretching vibrasi C=O dari gugus aldehid; dan 1641 cm -1 untuk gugus C=N yang terbentuk antara aldehid dan kitosan yang menunjukkan terjadinya fiksasi kitosan pada kain kapas tersebut. Poliester yang merupakan polimer sintetis dari asam tereftalat dan etilen glikol, dengan FTIR akan memberikan puncak-puncak pada bilangan gelombang 1750 -1725 cm -1 untuk stretching vibrasi C=O pada gugus ester, pada 1300 -1000 cm -1 untuk stretching vibrasi C-O.…”

ABSTRAKPada penelitian terdahulu, aplikasi kitosan pada kain poliester-selulosa (kapas/rayon) dengan teknik perendaman disertai proses untuk oksidasi selulosa dengan periodat yang menghasilkan gugus aldehida, telah menghasilkan kain poliester-selulosa antibakteri. Pada penelitian ini aplikasi kitosan pada kain poliester-selulosa dilakukan melalui 2 tahap proses modifikasi gugus poliester-selulosa yaitu proses untuk menempelkan gugus amina dari alkilamina (dodesilamina) pada serat poliester dilanjutkan dengan proses untuk oksidasi selulosa dengan periodat bersamaan dengan menempelkan kitosan pada serat poliester-selulosa termodifikasi. Diketahui bahwa pada teknik padding diperlukan waktu yang lebih singkat dan diperlukan larutan padding yang lebih sedikit dari pada larutan untuk cara perendaman, pada penelitian ini proses penempelan dilakukan dengan teknik padding 2 tahap. Digunakan kain poliester-selulosa yang tidak berwarna (kain grey) dan yang telah diberi warna yaitu hijau angkatan darat (AD) dan kain loreng. Hasil penelitian menunjukkan telah dihasilkan kain poliester-selulosa yang mempunyai sifat antibakteri. Sifat antibakteri yang diperoleh mempunyai durabilitas (ketahanan) terhadap pencucian yang baik yaitu setelah pencucian berulang setara 25 kali pencucian rumah tangga, ketahanan terhadap bakteri Staphylococcus aureus hampir tidak berubah yaitu turun 0-20%, sedangkan terhadap bakteri Escherichia coli ketahanan bakteri turun sebanyak 20-40%. Penempelan kitosan dengan cara padding 2 tahap tersebut pada kain poliester-kapas/rayon berwarna, walaupun memberikan peningkatan atau penurunan nilai K/S tetapi secara visual tidak mengakibatkan perubahan ketuaan warna yang signifikan. ABSTRACTExhaust method for anchoring chitosan onto polyester-cellulose fabrics has successfully produced antibacterial polyester-cellulose fabrics. As time and amount of solution needed in padding method were less than in exhaus method, in this research anchoring of chitosan onto polyester-cellulose fabrics was done using padding method. Two steps of padding method was done, the first step of padding for anchoring alkylamine onto polyester structure continued with the second step of padding for oxidizing cellulose structure with sodium periodate simultanneously with anchoring chitosan onto the modified polyester-cellulose structures. Grey and after dyed/printed of polyester-cotton/rayon fabrics were used. By means of the two steps of padding method, the polyester-cellulose fabrics having an antibacterial properties have been yielded. The achievement antibacterial properties have a good durability of washing, almost no change (decrease 0-20%) in resistance to staphylococcus aureus bacteria whereas resistance to escherichia coli bacteria 20-40% decreased after washing durabily tested. Padding method for anchoring of chitosan onto colored polyester-cellulose fabrics resulted no significant decreasing to the value/depth of fabrics colors.
