The properties of polysaccharide-based hydrogels can be effectively modified by developing an interpenetrating polymer network (IPN) for the purpose of controlled drug delivery. This study aims to unearth the potential of a more viscous, highly carboxylated xanthan (CX) gum as an additive in the design of IPN hydrogel beads with carboxylated guar (CG) gum and control of glimepiride release in simulated gastrointestinal milieu. The carboxylated gums were characterized by infrared spectroscopy, degree of substitution, and viscosity. The incorporation of CX up to 75% into CG matrix did not alter the spherical morphology of the beads after drug loading and ensured $69% drug entrapment efficiency. The CX as additive provided compatible environment for drug entrapment. Thermal and x-ray analyses suggested amorphous dispersion of drug in the IPNs. Depending on the concentration of CX, IPN hydrogels demonstrated variable swelling and drug release rate in simulated gastrointestinal pH. It was noticed that at least 25% CX as an additive could be beneficial in controlling drug release rate from the IPNs. The weight percent of CX influenced the drug release mechanism. Hence, the inclusion of CX as an additive in CG matrix seemed to be a promising approach for controlled drug release and further evaluations in vivo.

Cotton fabric dyed with natural madder dye exhibits poor dyeing properties.Although mordant improves the dyeing property of cotton fabric, it changes the madder dye colour tonality (the hue angle). In this study, ethylene glycol diglycidyl ether (EGDE) was used as a crosslinking agent to dye cotton fabrics with natural madder dye and improve the surface colour depth (K/S) and colour fastness.The molecular structure, crystal structure and surface morphology of crosslinked dyed cotton were analysed using Fourier Transform-infrared spectroscopy, Xray diffractometry and scanning electron microscopy, respectively. The results showed that crosslinked dyed cotton fabric had two different ether bonds, and that crosslinked dyeing mainly occurred in the amorphous area. Compared with direct dyed cotton fabric, the hue angle (h°) of crosslinked dyed cotton fabric did not undergo an obvious change, K/S increased by 5, and the rubbing fastness, washing fastness and light fastness increased by 2-3 levels, indicating that the dyeing property of cotton fabric with natural madder dye could be improved by using EGDE as a crosslinking agent. Compared with raw cotton fabric, the bending length of crosslinked dyed cotton fabric was reduced by 2.28 cm, the wrinkle recovery angle increased by 80.7° and the ultraviolet protection factor value was more than 40, indicating that crosslinked dyed cotton fabric had great softness, wrinkle resistance and excellent ultraviolet resistance. In addition, the water contact angle of the cotton fabric only changed slightly after crosslinking dyeing, and the crosslinked dyed cotton fabric still had good hydrophilicity. Therefore, EGDE was a viable crosslinking agent for cotton fabric with madder dye.How to cite this article: Cai X, Li H, Zhang L, Yan J.

Cotton fabrics were dyed with the madder and compounds of citric acid (CA) and dicarboxylic acids [tartaric acid (TTA), malic acid (MLA), succinic acid (SUA)] as cross-linking agents and sodium hypophosphite (SHP) as the catalyst. The molecular structures and crystal structures of the dyed cotton fabrics were analyzed using Fourier-transform infrared spectroscopy (FTIR) and X-ray diffractometry (XRD), respectively. The results showed that the polycarboxylic acids esterified with the hydroxyl groups in the dye and cellulose, respectively, and the reaction mainly occurred in the amorphous region of the cotton fabric. Compared with the direct dyed cotton fabric, the surface color depth (K/S) values of the CA, CA+TTA, CA+MLA, CA+SUA cross-linked dyed cotton fabrics increased by approximately 160%, 190%, 240%, 270%, respectively. The CA+SUA cross-linked dyed cotton fabric achieved the biggest K/S value due to the elimination of the negative effect by α-hydroxyl in TTA and MLA on esterification reaction, and the cross-linked dyed cotton fabrics had great levelness property. The washing and rubbing fastness of the cross-linked cotton fabrics were above four levels. The light resistance stability and the antibacterial property of the cross-linked dyed cotton fabrics was obviously improved. The sum of warp and weft wrinkle recovery angle (WRA) of the CA+SUA cross-linked dyed cotton fabric was 55° higher than that of raw cotton fabric, and its average UV transmittance for UVA was less than 5% and its UPF value was 50+, showing a great anti-wrinkle and anti-ultraviolet properties.
