Performance of cotton fabric treated with an amino-terminated hyperbranched polymer

Abstract

An amino-terminated hyperbranched polymer (HBP-NH 2 ), synthesized from methyl acrylate and diethylene triamine by polycondensation, was applied to treat cotton samples by a pad-dry-cure method. Physical properties, salt-free dyeability, antimicrobial activity, and antiultraviolet property of the treated cotton samples were tested. The crystallinity and mechanical properties, including breaking strength, breaking elongation, and Young's modulus of the treated cotton fibers, increased slightly in comparison with those of the untreated cotton fibers. The thermal stability and the moisture regain were also improved slightly. Dyed with direct dyes and reactive dyes in the absence of the electrolytes, the treated cotton fabric showed similar or higher color strength compared with the untreated cotton fabric in conventional dyeing. The treated cotton fabric can also be dyed with acid dyes effectively. In addition, the treated cotton fabric showed good antimicrobial activities against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The study of the antiultraviolet properties of the treated cotton fabric indicated that the HBP-NH 2 contributed to the reduction of UV transmission and the increase of UPF.

Synthesis and Characterization of an Amine‐Terminated AB2‐Type Hyperbranched Polymer and Its Application in Dyeing of Poly(ethylene terephthalate) Fabric with Acid Dye

“…This is of particular interest because the treatment with HBP can improve the ultraviolet protection property of PET fabrics. Such observation on cotton fabrics has already been reported in a publication …”

“…On the subject of cotton fabrics, the amino‐terminated hyperbranched polymers can act as a salt‐free dyeing auxiliary . Furthermore, it has shown that the application of the HBPs to cotton fabrics can reduce UV transmission and impart antibacterial properties …”

Synergetic reinforcements of epoxy composites with glass fibers and hyperbranched polymers

“…The hyperbranched polymer with amino terminal groups, HBPA, was synthesized by condensation polymerization of AB 2 ‐type monomers, details of which have been described elsewhere . Briefly, 52 mL of methyl acrylate were blended with 43 mL of diethylenetriamine in 100 mL of methanol for 6 h in an ice‐water bath.…”

Study on the Photocatalytic and Antibacterial Properties of TiO2 Nanoparticles-Coated Cotton Fabrics

“…In our previous study, an amino-hyperbranched polymer (HSDA) was synthesized. It was utilized to control synthesis of Ag and ZnO nanoparticles, and also served as a binder to impart and fix the nanoparticles on cellulose fabric to provide antimicrobial properties [19,20,21]. In this paper, amino-capped TiO 2 NPs were attempted to be synthesized by the sol-gel and hydrothermal method, using a mixture of tetrabutyl titanate (TBT)and amino polymers as a raw material.…”
