For improving wear properties of cotton fabric and exploiting ecological cotton textile with multifunction, cotton fabric was modified with anthraquinone extract of aloe. Aloe anthraquinone was fixed onto the surface of cotton fabric through the esterification crosslink of citric acid at high temperature using a pad-dry-cure process. The effects of citric acid concentration, catalyst concentration, aloe anthraquinone concentration and curing temperature on the treatment were mainly investigated. The optimized treating parameters for cotton fabric were obtained. The weight gain of modified fabric was significantly affected by the technical conditions. The breaking strength, moisture adsorption, wrinkle recovery angle, UV resistance and antibacterial properties of treated fabrics were respectively measured. The results showed that the wrinkle recovery angle of treated fabric markedly increased, whereas the breaking strength slightly decreased, and the moisture adsorption of fabrics kept almost unchanged. Additionally, the ultraviolet resistance and antibacterial property of modified cotton fabric became strong.

In order to take the advantage of the specific property of sericin to improve wear property of cotton fabric, cotton fabric was finished with sericin. Sericin was fixed onto the surface of cotton fabric in the presence of poly-carboxylic acids (CA and BTCA) at high temperature using a pad-dry-cure process. The effects of catalyst concentration, pH value, curing temperature and curing time on the finish were investigated. The optimized finishing conditions for cotton fabric were obtained. The weight gain of treated fabric with BTCA as crosslinking agent was higher than CA. The whiteness, breaking strength, moisture regain, permeability to gas and crease recovery properties of treated fabrics were measured. The results showed that wrinkle recovery angle evidently increased, and the wrinkle recover angle of BTCA combined secrin treated fabric was higher than CA. The breaking strength, moisture regain and whiteness of the treated fabric slightly decreased, the permeability to gas of cotton fabrics were not changed.

Cotton fabric with excellent antibacterial properties was obtained by treated with polyamide-amine (PAMAM) dendrimers as a carrier and silver nitrate as an antibacterial agent. The antibacterial cotton fabrics were prepared by the methods of one-bath process and two-bath process. Antibacterial activity of cotton fabrics treated by two different methods was good, but the antibacterial durability of cotton fabric treated with two-bath process was better than that treated with one-bath process. After 50 washing cycles, cotton fabric treated with two-bath process still had good antibacterial property and its inhibitory rate to Gram-positive S. aureus and Gram-negative E. coli was over 99 %. It was found that the breaking strength retention of finished cotton fabrics was 85.83 % and the decrease of cotton fabrics’ whiteness index was about 15 %.

Abstract Medical textiles are one of the most rapidly growing parts of the technical textiles sector of the textile industry. This work was developed for biocompatible materials of curcumin / TiO2 nanocomposite fabricated on the surface of cotton fabric for medical applications. Cotton fabric was pretreated with three crosslinking agents namely, citric acid, Quat-188, and GPTMS. Applying nanocomposite on modified cotton fabric using pad-dry cure method. The chemistry and morphology of modified fabrics are examined by Fourier-transformed infrared spectroscopy, energy-dispersive X-ray spectroscopy, and scanning electron microscopy. In addition, the chemical mechanism for nanocomposite modified fabric was reported. UV protection (UPF) and antibacterial properties against Gram - positive S. aureus and Gram - negative E. coli bacterial strains were investigated. The durability of fabrics to 20 washing cycles was also examined. Results demonstrated that nanocomposite modified cotton fabric exhibited superior antibacterial activity against Gram - negative bacteria that Gram - positive bacteria and excellent UV protection properties. Moreover, good durability was obtained, possibly due to the effect of the crosslinker used. Among the three pre-modification of cotton fabric, Quat-188 modified fabric reveals the highest antibacterial activity comparing with citric acid or GPTMS modified fabrics. This outcome suggested that curcumin / TiO2 nanocomposite Quatt-188 modified cotton fabric could be used in biomedical textile as antibacterial properties.

Durable press (DP) finishing process of cotton fabric with 1,2,3,4-butanetetracarboxylic acid (BTCA) was investigated and optimized using the Box-Behnken design (BBD) with a response surface methodology (RSM). BBD experimental data were fitted to create the response surface regression models describing wrinkle recovery angle (WRA) and breaking strength of the finished cotton fabric. Analysis of variance (ANOVA) revealed that the concentration of BTCA was the most significant variable affecting the WRA, followed by the curing time, curing temperature, and concentration of sodium hypophosphite (SHP). Regarding breaking strength, curing time was the most significant variable, followed by the curing temperature, concentration of BTCA, and concentration of SHP. After optimal treatment, the WRA of the finished fabric was 252°, while the retention rate of breaking strength was 69%.

Cotton fabric was treated by chitosan and epoxy-silicone finishing agents to improve its wrinkle-resistant property. The study showed that mixed finish by two agents can provide higher wrinkle-resistance than single finish when applied to the cotton fabrics due to their synergistic effect. In the wrinkle-resistant finishing process, four main factors (chitosan mass concentration, organosilicon volume concentration, baking temperature and baking time) influencing finish effect were discussed and then process conditions were determined. After optimum process treatment, the wrinkle-recovery angle of mixed finished cotton fabric increased evidently while its whiteness and breaking strength dropped a little. In addition, the addition of organosilicon can improve fabric softness. After washed for 30 times, delay wrinkle-recovery angle of mixed finished fabric was 54° higher than that of native fabric, and the treated cotton exhibited good washing resistance.

Bi-functional finishes of cotton such as wrinkle resistance with antibacterial and self-cleaning are important in textile industry. In this case, reducing cost and duration of processing is essential. For this purpose, cotton fabric was treated with different concentrations of maleic acid (MA), sodium hypophosphite (NaH2PO2) and Zno nanoparticles in two methods of  separately and simultaneously. Crease recovery angle and weight gain tests were examined. For measuring carboxylic acid groups of maleic acid treated cotton fabrics, methylene blue dye was used, and then, reflective spectrophotometer was used to determine methylene blue dye absorption .Self-cleaning and antibacterial properties of ZnO nanoparticles treated cotton fabric were investigated.  For measuring zinc amount, atomic absorption analysis was applied. As the Maleic acid concentration increased, weight gain, crease recovery angle and color yield increased. Color difference or self-cleaning effect of treated fabrics showed that by increasing maleic acid concentration, color difference increased in separate method. In simultaneous treatment, by increasing MA concentration and cross-linked sites, there was a slight increase in ∆E and self-cleaning effect. Results indicated that ZnO nanoparticles amount in separate method of treatment increased as compared with simultaneous method. Antibacterial performance decreased for simultaneous method of ZnO nanoparticles treatment.

The formaldehyde-free crease-proof finishing agent 1,2,3,4,-butanetetracarboxylic acid (BTCA) was used to treat lyocell fabrics. The effects of BTCA concentration and curing temperature on the wrinkle recovery angle (WRA) and tensile breaking strength of lyocell fabrics were discussed. The results showed that with the increase of BTCA concentration and curing temperature, the WRA value of lyocell fabrics increased obviously and the maximum WRA reached 147°, but breaking strength decreased gradually and the minimum strength retention was 68%. The WRA was durable against laundering. The fabric whiteness difference was not obvious and the whiteness retention of all samples exceeded 98%. After further alkali treatment, the WRA of the treated lyocell fabrics decreased and the fracture strength retention recovered to varying degrees (0.45–10.8%). The developed regression equations were found to be in good correlation ( r2 > 92%) with the selected variables (tensile strength, BTCA concentration, curing temperature). Fourier transform infrared spectroscopy analysis confirmed that the tensile strength loss of BTCA-treated lyocell fabrics was caused by cross-linking of cellulose molecules and acid degradation. Tensile strength loss that resulted from ester bonding could be restored after hydrolysis in alkaline solution. The recoverable magnitude of tensile strength was related to the curing temperature. A high temperature not only promoted the cross-linking of cellulose macromolecules, but also accelerated the acid degradation of cellulose.

Medical textiles are one of the most rapidly growing parts of the technical textiles sector in the textile industry. This work aims to investigate the medical applications of a curcumin/TiO2 nanocomposite fabricated on the surface of cotton fabric. The cotton fabric was pretreated with three crosslinking agents, namely citric acid, 3-Chloro-2-hydroxypropyl trimethyl ammonium chloride (Quat 188) and 3-glycidyloxypropyltrimethoxysilane (GPTMS), by applying the nanocomposite to the modified cotton fabric using the pad-dry-cure method. The chemistry and morphology of the modified fabrics were examined by Fourier transform infrared spectroscopy, energy-dispersive X-ray spectroscopy, and scanning electron microscopy. In addition, the chemical mechanism for the nanocomposite-modified fabric was reported. UV protection (UPF) and antibacterial properties against Gram-positive S. aureus and Gram-negative E. coli bacterial strains were investigated. The durability of the fabrics to 20 washing cycles was also examined. Results demonstrated that the nanocomposite-modified cotton fabric exhibited superior antibacterial activity against Gram-negative bacteria than Gram-positive bacteria and excellent UV protection properties. Moreover, a good durability was obtained, which was possibly due to the effect of the crosslinker used. Among the three pre-modifications of the cotton fabric, Quat 188 modified fabric revealed the highest antibacterial activity compared with citric acid or GPTMS modified fabrics. This outcome suggested that the curcumin/TiO2 nanocomposite Quat 188-modified cotton fabric could be used as a biomedical textile due to its antibacterial properties.
