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.

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 the anti-wrinkle finishing of cotton fabrics, the decreased dyeability of the finished fabrics has always been a difficult problem. A new anti-wrinkle finishing mode was developed to solve this problem by changing the finishing sequence of fabric dyeing and anti-wrinkle. In this research, the partial oxidization of raffinose with sodium periodate generated multiple aldehydes, which acted as multifunctional cross-linkers and endowed cotton fabrics with anti-wrinkle and hydrophilic properties. The structural characteristics of oxyRa were analyzed by FTIR and 13C-NMR. Through response surface methodology (RSM), the finishing model of oxyRa was established from the influencing factors of catalyst concentration, pH, curing temperature and time, and the optimized finishing process: the catalyst concentration was 20.12 g/L, pH was 4.32, curing temperature was 150 °C and curing time was 120 s. Under this condition, the predicted wrinkle recovery angle (WRA) of the finished fabric was up to 249.76°, Tensile strength (TS) was 75.62%, Whiteness index (WI) was 70.69. Importantly, comparing the anti-wrinkle and dyeing performance of the fabric with anti-wrinkle and then dyeing and anti-wrinkle after dyeing, the oxyRa-treated fabrics showed better dyeing properties compared with previously reported dimethyldihydroxyethylene urea (DMDHEU), glutaraldehyde (GA), and 1,2,3,4-butanetetracarboxylic acid (BTCA). Analysis of the combined mechanism of different finishing agents and cellulose, demonstrated the reason why oxyRa can be used to change the order of dyeing and anti-wrinkle finishing.

A series of modified nanoTiO2 photocatalysts, nanoPC, was applied to cotton fabrics through a pad-dry-cure process. The effect of nanoPC dosage, the ratio of nanoPC to crosslinking agent, and curing conditions on the degradation of formaldehyde were discussed. The optimal finishing process of cotton fabric with nanoPC was determined as follows: 1%~1.5% photocatalyst, curing at 130°C for 5 minutes. Cotton fabric treated with the above process demonstrated over 90% degradation of formaldehyde, good washing fastness and soft handle, as well as little loss in breaking strength, tearing strength and polymerization degree.

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.

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.

With the aim of polyester/cotton fabric one-bath one-step dyeing, polyester fabric low-temperature dyeing with cationic dyes was investigated based on β-cyclodextrin (β-CD) modification. After β-CD/citric acid (CA) modification, the hydrophilicity of the modified polyester fabric was improved obviously, which was demonstrated via moisture regain and contact angle, as well as wicking property. The optimal dyeing temperature and crosslinking agent were selected through comparing the color strength of the dyed polyester fibers. Modified polyester fabric obtained significantly enhanced color strength from 0.12 to 4 with a good leveling property when dyeing at 70℃ using CA as the crosslinking agent. β-CD modified polyester/cotton fabric displayed a K/ S value of 8.61, much higher than the value of 0.71 of the unmodified fabric with cationic dyes, showing a highly improved dyeing ability. The color fastness of β-CD modified polyester/cotton fabrics, including washing fastness, rubbing fastness, perspiration fastness and light fastness, are all over grade 3–4 when the curing temperature of 180℃ is adopted for β-CD modification, demonstrating that polyester/cotton fabric one-bath one-step dyeing can be realized based on β-CD modification.

This study establishes an eco-friendly anti-wrinkle treating process for cotton fabric. Sodium hydroxide-liquid ammonia pretreatment followed by 6% (w/w) PU100 adding citric acid pad-cure-dry finishing. In this process, citric acid (CA) was used as the fundamental crosslinking agent during finishing because it is a non-formaldehyde based, cost-effective and well wrinkle resistance agent. Environmental-friendly waterborne polyurethane (WPU) was used as an additive to add to the CA finishing solution. Six commercial WPUs were systematically investigated. Fabric properties like wrinkle resistance, tensile strength retention, whiteness, durable press, softness, and wettability were well investigated. Fourier transform infrared spectra and X-ray diffraction spectra were also measured and discussed before and after adding waterborne polyurethane. Tentative mechanism of the interaction among the WPU, CA, and modified cotton fabrics is provided. The effect of cotton fabric pretreatment on fabric performance was also investigated. After the eco-process’s treatment, the fabric wrinkle resistant angle was upgraded to 271 ± 7°, tensile strength retention was maintained at 66.77% ± 3.50% and CIE whiteness was elevated to 52.13 ± 3.21, which are much better than the traditional CA anti-wrinkle finishing based on mercerized cotton fabrics. This study provides useful information for textile researchers and engineers.
