“…Moreover, it is predominantly cellulose polymer (linear b-1,4 glucan), and its chemical reactivity is the same as that of the cellulose polymer (Lewin 2010;Schindler and Hauser 2004). On the other hand, a number of previous works (Chattopadhyay et al 1999;Karthik et al 2012;Maulik et al 2011;Shao et al 2004; reported that citric acid as an inexpensive and nontoxic crosslink agent was used to improve the wrinkle resistance of cotton fabric through an esterification between them. Meanwhile, cotton fiber has been easily modified to become carboxylic fiber because of the introduction of several carboxylic groups into its molecular structure (Chattopadhyay et al 1999;.…”

Woven cotton fabric was first modified with citric acid by a conventional pad-dry-cure process and then coordinated with Fe(III) ions to prepare a Fe(III)-modified cotton fiber complex. After the characterization by SEM, FTIR, XPS, XRD and DRS, this complex was used as a heterogeneous Fenton catalyst for the degradation of a typical textile dye, Acid Red 88, under visible irradiation. Some factors affecting the modification process, such as the citric acid and NaH 2 PO 4 concentrations as well as the curing temperature, were also investigated with respect to the coordinating performance of the modified fabric and the catalytic activity of its Fe complex. The results indicated that cotton fabric could be esterified with citric acid to impart the carboxylic groups, which successfully reacted with Fe(III) ions to form the complex. Dye degradation was significantly accelerated by the presence of the complex under visible irradiation. Increasing the concentrations of citric acid, NaH 2 PO 4 or the curing temperature enhanced the carboxyl group content of the modified fiber as well as Fe content and catalytic activity of its complex. However, an excessive amount of citric acid and NaH 2 PO 4 or a curing temperature higher than 140°C reduced the Fe content and catalytic activity of the complex. A higher initial H 2 O 2 concentration promoted the dye degradation. The excellent catalytic and mechanical performance was also found in its reuse processes.

“…They showed great light fastness, and the CA+SUA cross-linked dyed fabric had the best effect (4~5 levels). The great light resistance in the presence of the dyed cotton fabrics was explained by the fact that the diffusion of oxygen and moisture become difficult in the polycarboxylic acid cross-linked structure, which negatively affects the initiation of the photofading mechanism [13,34].…”

“…However, the excessively high cost of the BTCA has prevented its application [12]. The citric acid (CA) is a cheap and environment-friendly finishing agent for the cotton fabric [13]. But, compared with the BTCA, fewer carboxyl groups in its molecular structure and the negative effect of α-hydroxyl in CA on the esterification reaction, so the cross-linking efficiency for the cotton fabric is reduced [14].…”

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.

“…9 Common crosslinking agents can be divided into carboxylic acids, resins and epoxies. Maulik et al 10 used citric acid as an esterification crosslinking agent to increase the K/S and colour fastness of cotton fabric dyed with natural dyes from Punica granatum and Camellia sinensis. The wrinkle recovery angle (WRA) of the cotton fabric increased, but the tensile strength decreased (−30%).…”

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.
