  • Antibacterial Finish of viscose nonwovens with pamam ag
    Dyeing & Finishing, 2012
    Co-Authors: Zhu Ping
    Abstract:

    Antibacterial Finish is carried out on viscose nonwovens by padding-drying-curing method with polyamidoamine(PAMAM) dendrimer as carrier and silver nitrate solution as antimicrobial agent.The results show that the optimum Antibacterial Finish process is treating with 3% PAMAM dendrimer and 2.0×10-3 mol/L silver nitrate solution.The Finished viscose nonwovens have durable Antibacterial effect with inhibition of Escherichia coli of 98% and Staphylococcus aureus of 97%.The tensile strength of treated fabric improves by 41%,the breaking elongation decreases by 25% and the whiteness reduces by 18%.

  • Antibacterial Finish of cotton fabric with pamam ag
    Dyeing & Finishing, 2010
    Co-Authors: Zhu Ping
    Abstract:

    Antibacterial Finish of cotton fabric was carried out with polyamidoamine(PAMAM) dendrimer as a carrier and silver nitrate as an Antibacterial agent.Cotton fabric treated with two-bath process had better durable Antibacterial effect with inhibition of staphylococcus aureus and escherichia coli more than 99% after 50 times laundering.Tensile strength retention of treated fabric was 85.83%,and whiteness dropped by about 15%.

  • core shell particles containing poly n butyl acrylate cores and chitosan shells as a novel durable Antibacterial Finish
    ACS symposium series, 2007
    Co-Authors: Man Fai Leung, John Haozhong Xin, Tsz Leung Kwong, Daniel Kam Len Lee
    Abstract:

    A novel Antibacterial coating for cotton fabrics has been developed using core-shell particles that consist of poly(n-butyl acrylate) (PBA) cores and chitosan shells. The spherical particles were prepared via a surfactant-free emulsion copolymerization of n-butyl acrylate in an aqueous chitosan solution. The particles had a narrow particle size distribution with average diameter of approximately 300 nm, and displayed highly positive surface charges. Transmission electron microscopic (TEM) images clearly showed well-defined core-shell morphology with PBA cores and chitosan shells. Cotton fabric was coated with PBA-Chitosan particles through a conventional pad-dry-cure process without using any chemical binders. Fabric Antibacterial efficiency was evaluated quantitatively against Staphylococcus aureus by using the shake-flask method. The results showed that particle-coated fabric had an excellent Antibacterial property with bacterial reduction more than 99 %. The durability of the Antibacterial property was maintained above 90 % bacterial reduction even after 50 times of home laundering. Effects of particles coating on fabric hand, air permeability, break tensile strength and elongation, as well as fabric surface morphology, were investigated.

  • durable Antibacterial Finish on cotton fabric by using chitosan based polymeric core shell particles
    Journal of Applied Polymer Science, 2006
    Co-Authors: John Haozhong Xin, Kam Len Lee, Tsz Leung Kwong
    Abstract:

    Cotton fabric with excellent Antibacterial durability was obtained when treated with chitosan-containing core-shell particles without any chemical binders. These amphiphilic nanosized particles with Antibacterial chitosan shells covalently grafted onto polymer cores were prepared via a surfactant-free emulsion copolymerization in aqueous chitosan. Herein, two core-shell particles, one with poly(n-butyl acrylate) soft core and another with crosslinked poly(N-isopropylamide) hard core, were synthesized and applied to cotton fabric by a conventional pad-dry-cure process. Antimicrobial activity was evaluated quantitatively using a Shake Flask Method in which the reduction of the number of Staphylococcus aureus cells was counted. The results showed that treated fabric had an excellent Antibacterial property with bacterial reduction higher than 99%. The Antibacterial activity maintained at over 90% reduction level even after 50 times of home laundering. The fabric surface morphology as well as the effect of latex particles with different core flexibilities on fabric hand, air permeability, break tensile strength, and elongation was investigated. © 2006 Wiley Periodicals, Inc.

  • Antibacterial Finish of cotton fabrics with quaternary ammonium salt of chitosan
    Dyeing & Finishing, 2013
    Co-Authors: Liao Sha
    Abstract:

    Quaternary ammonium salt of chitosan HACC is prepared with glycidyl trimethyl ammonium chloride and chitosan and is applied to Antibacterial Finish of cotton fabric. The process of antimicrobial Finish is optimized through single factor and orthogonal experiments. The Antibacterial activities of Finished fabrics with chitosan and HACC respectively are tested and compared. The results show that under conditions of 4. 0% citric acid,HACC 1 g / L,0. 2% triethanolamine,the molar ratio of sodium hypophosphite and citric acid is 1 ∶ 1,bath ratio 1 ∶ 50,dipping at 60℃ for 30 min,pre-drying at 80 ℃ for 5 min,curing at 165 ℃ for 1 min,the Finished cotton fabric features good Antibacterial properties to escherichia coli and staphylococcus aureus,as well as the improved anti-wrinkle property.
