Summary of "Polyaconitic acid/functional amine/azo dye composite as a novel hyper-branched polymer for cotton fabric functionalization."

A new hyperbranched polymer based on aconitic acid and two different amine (triethnaol amine and diethylenetriamine) with different functional groups; hydroxyl and amine groups respectively was successfully synthesised by A2B3 polymerization technique and characterised using Fourier Transform Infrared (FT-IR), Nuclear Magnetic Resonance (NMR), rheological properties, antimicrobial and cytotoxicity activity. In addition, a new heterocyclic azo dye was synthesised and characterised using FT-IR, NMR, mass spectra and antimicrobial activity. Characterisation provides that both composites and azo dye have been well prepared. A mixture from both hyberbranched polymer and synthesised azo dye have been applied to cotton fabrics. Evaluation of treated fabrics shows that, the surface of treated fabrics has a thin film from applied composite which coated the whole fibre surface. Treated fabrics have good antimicrobial activity against gram positive, gram negative bacteria and fungi. Fastness properties, physical and mechanical properties for treated fabrics were also evaluated.

Medical and Biotech [MESH] Definitions

A graft consisting of multiple tissues, such as muscle, bone, nerve, vasculature, and skin, comprising a functional unit for reconstructive purposes.

An X-linked hyper-IgM immunodeficiency subtype resulting from mutation in the gene encoding CD40 LIGAND.

Transference of multiple tissues, such as muscle, bone, nerve, and skin, as a functional unit for reconstructive purposes. Blood supply to the transplanted tissues is maintained throughout the transplantation procedure with minimal ischemia. Maintenance of vascularity in the graft promotes its viability, function, and survival in the recipient.

A 20-carbon branched chain fatty acid. In phytanic acid storage disease (REFSUM DISEASE) this lipid may comprise as much as 30% of the total fatty acids of the plasma. This is due to a phytanic acid alpha-hydroxylase deficiency.

An amino acid formed in vivo by the degradation of dihydrouracil and carnosine. Since neuronal uptake and neuronal receptor sensitivity to beta-alanine have been demonstrated, the compound may be a false transmitter replacing GAMMA-AMINOBUTYRIC ACID. A rare genetic disorder, hyper-beta-alaninemia, has been reported.
