“…On the other hand, poly(carboxylic acid)s, especially citric acid, have become a popular crosslinking agent; it is able to overcome toxicity and is less costly than the previously mentioned compounds. Citric acid has already been used in the esterification or crosslinking of some polysaccharides, for example, starch4 or cellulose,5–7 and polyhydroxy compounds, such as aliphatic diols,8, 9 glycerol,10 1,4 : 3,6‐dianhydrohexatols,11 sorbitol,12 and also CDs 13–25. Citric acid has also been used as a crosslinking agent for the grafting of CDs onto various materials to enhance their sorption properties.…”

“…A similar method was applied to develop a medical material that could be loaded by antimicrobial agents by the grafting of CDs onto microporous poly(vinylidene difluoride) membranes 17. Citric acid–CD mixtures have also been used in wool, polyester, and cotton fabric finishing 18–20. In this case, cotton material was impregnated with a solution of citric acid, CD, and a catalyst; dried; and cured at 170–190°C.…”

“…15–20%) was the consequence of cellulose esterification and CDP formation 18. The properties of CD‐grafted materials have been the subject of several studies,13–20 but none of them focused on the polyesters, even though the polymers are the most important component of the formed coating. Moreover, the number of articles dealing with the chemical structure and properties of CDPs is very limited 22–24…”

We synthesized water-insoluble polymers, poly(b-cyclodextrin-co-citric acid)s, by heating a mixture of citric acid, cyclodextrin (CD), and Na 2 HPO 4 as a catalyst with a 6 : 1 : 2 molar ratio at 160, 170, and 180 C for 10 and 20 min. The chemical composition of the polyesters was determined by high pressure liquid chromatography (HPLC) analysis of the polymer hydrolysates. The crosslinking mechanisms and thermal degradation of the polymers were also investigated. The polyesters contained 30-35% citric acid, 1-4% unsaturated carboxylic acids (i.e., itaconic, cis-aconitic, trans-aconitic, and mesaconic acids), and 60-70% CD, whereas about 40% of them were able to form inclusion complexes.

Today, the need for fabrics that resist the growth of microorganisms is rising rapidly, as bacteria and other microbes are resistant to any clean room environment. In particular, health care and hygiene textile products must be more bacterial resistant. This study thus concentrated on developing antibacterial surgical textile products using eco-friendly material, such as casein and banana peel, which were used to coat fabric using cyclodextrin as a cross-linking agent. In this research work, fabric was treated with banana peel, casein, and a combination of banana peel and casein, without cyclodextrin, while cyclodextrin-loaded fabric treated samples were tested for antimicrobial resistance (AATCC100-2004). The treated samples initially studied using FTIR showed a peak point at 3,278.99 cm-1, which infers the presence of an O-H group for banana peel extract, and at 3,340.71 cm-1, which infers the presence of an N-H group for casein. Antimicrobial tests against E. coli showed a bacterial reduction of 81.44%, while a reduction of 52.80% was recorded for S. aureus. An analysis of untreated and treated samples showed that treatment with extracts of an agent through the pad-dry-cure process did not have a significant effect on the tensile and air permeability characteristics of the samples.

The impact of the pre-treatment of cellulose material in NaOH solution and of microwave radiation on the mechanism of crosslinking β-cyclodextrin with cellulose was investigated in this paper. Citric acid and Na-hypophosphite as catalysts were applied for better crosslinking. Inclusion compounds with tea tree essential oil and cyclodextrines grafted onto cotton fabric were made in order to verify that cavities were available for inclusion compounds. The permanence of β-CD on the cellulose fabrics treated was tested by ISO 6330:2012. The properties and structure of the materials treated were characterised by Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The breaking force and mechanical damage of the materials were determined according to EN ISO 13934- 1:1999. The results indicated better bonding between cellulose and β-cyclodextrin where microwave treatment was applied, the phenomenon of which is of great importance for long lasting wash durability. In order to quantify the odour releasing behaviour of β-CD treated cellulose fabrics, olfactometric determination of the intensity of odour was undertaken.
