Flame Retardant Finishing and Dyeing of Cotton Fabric in One Bath
AATCC Journal of Research, 2020Co-Authors: Chaohong Dong, Xiaoyan Chen, Peng Wang, Zhiming Jiang, Yun Liu, Ping ZhuAbstract:Flame resistant Cotton Fabric is usually dyed first, and is then treated with a flame retardant by the pad-dry-cure technique. In this research, Cotton Fabric was treated with 2-(2-aminoethyl hydrogen phosphite)-4,6-dichloro-1,3,5-triazine (APDCT). APDCT contains s-triazine groups, which are the same used by reactive dyes. This process allows Cotton Fabric dyeing and flame retardant treatment to occur simultaneously, while decreasing treatment temperature, improving efficiency, and saving energy. Optimal treatment was determined by the percent dye uptake, fixation, and Fabric flame resistance. The color fastness to rubbing of the treated Cotton Fabric was almost unchanged. The tensile strength of the treated Cotton Fabric was slightly reduced.

Preparation and flame retardancy of reactive flame retardant for Cotton Fabric
Journal of Thermal Analysis and Calorimetry, 2018Co-Authors: Xiaoyan Chen, Ping Zhu, Jian Liu, Guodong Fan, Shuying Sui, Chaohong DongAbstract:Monochlorotriazine aminopropyl silanol phosphate (MCASP) was synthesized as a novel flame retardant agent for Cotton Fabric. It was characterized by FTIR, 1H, 13C and 31P NMR. The flame retardancy of the Cotton Fabric treated with MCASP was characterized by limiting oxygen index (LOI), and the vertical burning test. The Cotton Fabric treated with 300 g L−1 MCASP obtained the best flame retardancy with a LOI value of 31.0%, and the char length decreased to 4.5 cm. Combustion behaviors of treated Cotton Fabric were tested by cone calorimeter. The ignition time increased, and the values of total heat release, heat release rate, mass loss decreased. The surface morphology of the residues and the thermal stability of Cotton Fabric were investigated by scanning electron microscopy and thermogravimetric analysis, respectively. The chemical structure of residue of treated Cotton Fabric was studied by FTIR. The results showed that MCASP played a protective role on the degradation of Cotton Fabric, hindered the formation of volatile species and favored the formation of char. What is more, the strength and durability of treated Fabric were studied by tear force test and washing durability test, respectively.

RSC Advances, 2019Co-Authors: Ishaq Ahmad, Chi Wai Kan, Zhongping YaoAbstract:Development of textile materials with tailored properties by coating with nano-materials is an emerging field of research. The preparation and characterization of photoactive Cotton Fabric for UV protection and self-cleaning properties are reported herein. In this study, a photoactive sol comprising of a reactive blue dye, C.I. Reactive Blue 21 (RB-21), and TiO2 was prepared by using sol gel method. The TiO2 nano sol was mixed with RB-21 to extend its photocatalytic activity in the visible region of the solar spectrum. The Cotton Fabric was coated with the RB-21/TiO2 sol via dip-pad-dry-cure method. Surface characterization of the coated Cotton Fabric was performed by FTIR-ATR, UV-visible absorption, XRD and SEM studies. FTIR-ATR and UV-visible spectra confirmed stable attachment of the photoactive RB-21/TiO2 coating on the Cotton Fabric. SEM images and XRD pattern shown the presence of anatase TiO2 on the coated Cotton Fabric. UV-protection, photocatalytic performance and self-cleaning properties of the coated Cotton Fabric were evaluated by the UV transmittance spectra, degradation of Rhodamine B (RhB) dye and stain removal under visible light respectively. Degradation of RhB was observed in the presence of RB-21/TiO2 coated Cotton when exposed to visible light. Moreover, the coated Cotton Fabrics displayed excellent UV protection properties.

Journal of Applied Polymer Science, 2006Co-Authors: Cwm Yuen, Chi Wai Kan, Wai Keung Wong, H. L. LeeAbstract:Cotton Fabrics were treated with montmorillonite (MMT) so as to improve the wrinkle-resistant properties of the Cotton Fabrics. The MMT in emulsion form was applied by padding method to the Cotton Fabrics, and the wrinkle-resistant properties of the MMT-treated Cotton Fabrics and the wrinkle-resistant properties of MMT-treated Cotton Fabrics were consequently improved. Furthermore, different instrumental methods were used for studying the distribution of MMT particles on the Cotton Fabric surface. It was noted that near nano-scale MMT particles were adhered on the fiber surface, and in addition, the particles size played an important role in influencing the wrinkle-resistant properties of the Cotton Fabric. © 2006 Wiley Periodicals, Inc.

zno carboxymethyl chitosan bionano composite to impart antibacterial and uv protection for Cotton Fabric
Carbohydrate Polymers, 2011Co-Authors: El A Shafei, A AbouokeilAbstract:Abstract ZnO/carboxymethyl chitosan bionano-composite was prepared at different temperatures. ZnO/carboxymethyl chitosan bionano-composite was characterized by UV spectroscopy, FTIR and transmission electron microscope (TEM). The results obtained confirmed the formation of the bionano-composite. The mean sizes of ZnO and carboxymethyl chitosan particles were ≈28 nm and ≈100 nm, respectively. The obtained bionano-composite was used as a finishing agent for Cotton Fabric to impart UV protection and antibacterial properties (multifunctional finishing) to Cotton Fabric. The finishing was carried out using pad-dry-cure method. Cotton Fabric was characterized by measuring scanning electron microscope (SEM), X-ray diffraction (XRD), UPF ratting and antibacterial properties. Finished Cotton Fabric exhibits very good antibacterial properties against Gram positive and Gram negative bacteria which increased with increasing the composite concentration and also has a good UV protection which increased with increasing the temperature of curing.

Highly efficient flame-retardant and soft Cotton Fabric prepared by a novel reactive flame retardant
Cellulose, 2019Co-Authors: Fang Xu, Fengxiu Zhang, Ling Zhong, Yuan Xu, Cheng Zhang, Guangxian ZhangAbstract:The flame resistance of Cotton Fabric was greatly enhanced by a novel reactive flame retardant with serrated structure, ammonium salt of 1,3-diaminopropane tetra-(methylenephosphonic acid) (ADDTMPA), and the softness of Cotton Fabric was retained very well. The results showed that Cotton Fabric modified by 30% ADDTMPA had a LOI value of 41.5%, which remained well after 40 laundering cycles with a LOI value of 26.3%. The treated Cotton Fabric was not ignited in vertical flammability tests, and the results of cone calorimetry proved that the heat release rates and total heat release of treated Cotton Fabric decreased substantially. TG analysis showed that the treated Cotton Fabric had the lower initial decomposition temperature and more residues than control Cotton Fabric during combustion. TG-IR analysis showed that the treated Cotton Fabric released much less flammable volatile species than control Cotton Fabric. FTIR analysis indicated that the flame retardant was reactive in condensed phase and the flame retardant was grafted on cellulose by P–O–C bonds. EDX results showed that a large amount of phosphorus was introduced into the Cotton Fabric. SEM showed that the modification had little effect on the surface of Cotton fibers, and a large amount of residue was maintained after combustion. The treatment by ADDTMPA could produce highly effective flame-retardant and soft Cotton Fabric. A novel phosphorus-based, halogen-free and formaldehyde-free flame retardant with serrated structure and reactive groups was synthesized to prepare highly efficient flame-retardant and soft Cotton Fabric by chemical grafting.

Dyeing of Cotton Fabric Modified by 2, 3-Epoxpropyl Triethyl Ammonium Chloride with Reactive Dyes
Advanced Materials Research, 2013Co-Authors: Hui Liang, Guangxian Zhang, Fengxiu Zhang, Hui ZhengAbstract:In order to improve the dyeing property of Cotton fiber, in this paper, the Cotton Fabric was modified by 2, 3-epoxpropyl triethyl ammonium chloride (ETEAC). Four reactive dyes were employed to test the dyeing property of modified Cotton Fabric. The results showed that the dyeing property of Cotton Fabric was improved greatly. When the concentration of ETEAC was equal to or above 7%, most of the dye-uptake rate of the modified Cotton Fabric could reach to nearly 100%. And the dyeing rate was very high. These suggested that the cationic groups with three ethyls could attract anion dyes efficiently, though the cationic groups with three ethyls were greater than cationic groups with three methyls. The modified Cotton Fabric could not be dyed uniformly. Sodium dodecyl sulfate (SDS) was efficient retarder for the modified Cotton Fabric.
