Frederico Nogueira,Joana Vaz,Claudia Mouro,Erhan Piskin,Isabel Gouveia 한국생물공학회 2014 Biotechnology and Bioprocess Engineering Vol.19 No.3

In the past years the textile industry haswitnessed new advances in the area of textile fiber chainsengineering, which allow the modification of the structureof such chains so as to produce polymers responsive tochanges in the environment, thus capable of attaching tocells and bioactive molecules. On the other hand, followingour society's trend towards higher hygiene standards, theresearch and development of antimicrobial textiles hasshown a remarkable increase. Applications of such textilescan nowadays be found in underwear, sportswear, homefurnishing, protective clothing, wound-dressings and inmicrobial infection high risk settings, such as health careinstitutions. The present research aims at the developmentof a strong, durable and washable antimicrobial L-Cysteine(L-Cys)-functionalized cotton by means of a covalentmechanism. The covalent binding of L-Cys onto cellulosicfibers was assessed by Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDS) andFourier Transform Infrared Spectroscopy (FTIR) analysis. Antimicrobial assays showed that the functionalized cottonyielded strong microbial killing rates, exhibiting inhibitionratios of 89 and 83% against K. pneumoniae and S. aureus,respectively. These results demonstrate the effectiveness ofthe covalent modification of cotton fabrics with L-Cysadding antimicrobial properties to cotton fibers and thusopen the door to a world of applications in the area ofincreased risk microbial infections.

Diabetes mellitus is a chronic disorder which affects millions of population worldwide. Global estimates published in 2010 reported the world diabetic prevalence as 6.4%, affecting 285 million adults. Foot ulceration and wound infection are major forms of disabilities arising from diabetic diseases. This study was aimed to develop a natural antimicrobial finishing on medical grade textile that meets American Association of Textiles Chemists and Colorists (AATCC) standard. The textile samples were finished with the ethanolic extract of Penicillium amestolkiae elv609, an endophytic fungus isolated from Orthosiphon stamineus Benth (common name: cat`s whiskers). Endophyte is defined as microorganism that reside in the living plant tissue, without causing apparent disease symptom to the host. The antimicrobial efficacy of the ethanolic extract of P. minioluteum was tested on clinical pathogens isolated from diabetic wound. The extract exhibited significant inhibitory activity against 4 bacteria and 1 yeast with the minimal inhibitory concentration ranged from 6.25 to 12.5 mg/mL. The results indicate different susceptibility levels of the test microorganism to the ethanolic extract. However, the killing activity of the extract was concentration-dependent. The finished medical textile showed excellent antimicrobial efficacy on AATCC test assays. All the microbial cultures treated with the textile sample displayed a growth reduction of 99.9% on Hoheinstein Challenge Test. The wash durability of the finished textile was found good even after 50 washes with commercial detergent. Besides, the gas chromatography mass spectrometry analysis showed that 6-octadecenoic acid and diethyl phthalate were the main bioactive constituents of the extract. In conclusion, the developed medical textile showed good antimicrobial efficacy on laboratory tests. This work can be extended to in vivo trials for developing healthcare textile products for antimicrobial applications.

실리콘 반응성기가 도입된 Poly(hexamethylene guanidine hydrochloride)를 이용한 섬유제품의 항미생물 가공-처리방법과 섬유 종류에 따른 내세탁성 변화-

김영호,최재원 한국섬유공학회 2001 한국섬유공학회지 Vol.38 No.8

Poly(hexamethylene guanidine hydrochloride) containing silicone reactive groups (PHGS) was used as an antimicrobial finishing agent for textile fabrics, and the effects of treatment methods and kind of fibers on the laundering durability of antimirobial activity were studied. The antimicrobial activity of PHGS-treated cotton fabrics was not affected by the treatment methods such as padding methods, padding temperature, drying or curing conditions. They showed excellent antimicrobial activity even after laundering with alkaline detergents. On the other hand the synthetic fiver fabrics, such as PET, nylon 6, and acrylics, treated with PHGS solution under various conditions exhibited no antimicrobial activity after launderings although they showed excellent antimicrobial activity before laundering. These results ruled out the possibility that the durability in the case of cotton fabrics may come from the formation of insoluble crosslinked film on the fiber surface via self-crosslinking between hydroxyl groups in PHGS. They rather confirmed the suggestion that the reactions between PHGS and hydroxyl groups in cellulose impart laundering durability to PHGS treated cotton fabric.

Vijay D. Gotmare,Sushant S. Kole,Rajani B. Athawale 한국의류학회 2018 Fashion and Textiles Vol.5 No.1

Development of nanostructured textile material using sustainable finishing route and to evaluate its performance in the areas like wound management is challenging task. Stable and eco-friendly o/w nanoemulsion of tetrahydroxy curcumin derivative was developed by using high pressure homogenization method. The stable nanoemulsion for the selected drug was developed and evaluated for appearance, particle size distribution (100–300 nm), zeta potential (− 30.1 to − 31.1 mV) and drug content (80–83.3%). Nanoemulsion containing antimicrobial drug were impregnated on the textile material by exhaust methods using β-cyclodextrin and polycarboxylic acid as a crosslinking agent. Treated textile material is evaluated for its antimicrobial activity against standard antimicrobial strip using both AATCC 147 and AATCC 100, treated samples shows positive results against both positive and negative bacteria. Current eco-friendly technique would be innovative step towards development of medical textile for wound care applications.

Measurement of antibacterial properties of foil‑backed electrospun nanofibers

Mary Ann Wagner‑Graham,Herbert Barndt,Mark Andrew Sunderland 한국의류학회 2019 Fashion and Textiles Vol.6 No.1

Current methodologies for evaluation of antibacterial properties of traditional textiles are not applicable to foil-backed, poorly-absorbent electrospun nanofiber materials, since existing test methods require absorbent fabrics. Since electrospun nanofibers are adhered to the foil backing only by electrostatic interactions, methods used to evaluate antibacterial properties of surfaces cannot be used because these protocols cause the nanofibers to lift from the foil backing. Therefore, a novel method for measurement of the antibacterial properties of electrospun metallic foil-backed nanofiber materials was developed. This method indicated that acetate-based nanofibers manufactured to contain 5 to 30 weight percent of cold-pressed hemp seed oil or full-spectrum hemp extract inhibited the growth of Staphylococcus aureus in a dose-dependent manner, from 85.3% (SEM = 2.2) inhibition to 99.3% (SEM = 0.15) inhibition, respectively. This testing method represents an advanced manufacturing prototype procedure for assessment of antibacterial properties of novel electrospun, metallic foil-backed nanofiber materials.

친환경 니트 텍스타일 디자인 연구- 전통섬유 공예기법과 천연염료의 기능성 활용을 중심으로 -

This paper presents a procedure for developing knit fabric designs using environment friendly techniques and natural dyeing. Working on the concept of environment friendly design first advocated by 19th century English artist William Morris 1) we researched on the colorfastness and antimicrobial effect of silk fabrics dyed with environment friendly material, 2) identifying environment friendliness of test fabrics, we dyed silk yarns and wool yarns using the same methods that we used for collecting data, 3) we made knit mufflers and lap robes using naturally dyed yarns. Though not easily applicable to mass production system, the process we suggest here will be useful for knit fabric designers who want to restore 'simple and beautiful' life styles in Morris's sense. We believe that the data and design process suggested here could be generally applied to textile industry in the future, considering the trend in the modern textile design which emphasizes eco-friendly as well as artistically refined textile works.

Toufque Ahmed,R. Tugrul Ogulata,Osman Gülnaz 한국섬유공학회 2023 Fibers and polymers Vol.24 No.11

Green synthesis is a widely known silver nanoparticle (AgNPs) synthesis method. Hundreds of biological extracts have been applied for synthesizing of AgNPs. This study used C. reticulata, C. sativus and C. arvensis as plant extracts for AgNPs synthesis. It depicted the supremacy of C. arvensis in green synthesis. Here, we compared the nanoparticle’s morphology and antibacterial activity of C. arvensis synthesized AgNPs with other previously accomplished works on different plant extracts. The AgNPs were incorporated in cotton fabrics with multiple methods. We used FTIR, UV–Vis, SEM, EDS, XRD, antibacterial activity, and wash fastness for characterization. The SEM image shows C. arvensis plant can synthesize different shapes, whereas C. reticulata synthesizes nearly spherical shapes. It also showed the C. arvensis plant extract exhibited 96% antibacterial activity after 20 washes with double padding methods, which is the best among the available works on antibacterial wash fastness without any binder or cross-linkers. In contrast, Citrus reticulata showed 88% antibacterial activity after five washes.

김정수,김태희,이기훈,Kim, Jung Soo,Kim, Tae Hee,Lee, Ki Hoon 한국섬유공학회 2016 한국섬유공학회지 Vol.53 No.4

Chitosan nonwoven fabric (CNF) was treated with silk sericin (SS) in order to introduce deodorant ability. CNF was activated with glutaraldehyde followed by reaction with SS. The attachment of SS onto the surface of chitosan fibers was confirmed with ATR-FTIR, FE-SEM and elementary analysis. It was found that about 81.18 mg of SS can be attached per gram of CNF after 3 hrs of reaction. The introduction of SS improved the deodorant ability of CNF by removing 89.0 % of $NH_3$ gas, which was about 1.4 times of that of neat CNF. More interestingly, the antimicrobial effect of CNF was also enhanced after SS treatment.
