“…Meanwhile, the optimal Na 2 CO 3 concentration of cationic cotton (25 g/L) was lower than that of untreated cotton (40 g/L). The reason is that some reactive dyes could be spontaneously adsorbed on the cationic cotton fibers through electrostatic attraction [24], leading to the higher dye fixation rates and the lower Na 2 CO 3 consumption compared with the untreated cotton fabrics.…”

The Poly[Styrene-Butyl acrylate-(P-vinylbenzyl trimethyl ammonium chloride)] P(St-BA-VBT) nanospheres with N + (CH 3 ) 3 functional groups were successfully prepared and applied to modify cotton fabrics using a pad-dry process. The obtained cationic cotton fabrics were dyed with pad-steam dyeing with reactive dye. The results show that the appropriate concentration of nanospheres was 4 g/L. The sodium carbonate of 25 g/L and steaming time of 3 min were suitable for dyeing cationic cotton with 25 g/L of C.I. Reactive Blue 222. The color strength and dye fixation rates of dyed cationic cotton fabrics increased by 39.4% and 14.3% compared with untreated fabrics. Moreover, sodium carbonate and steaming time were reduced by 37.5% and 40%, respectively. The rubbing and washing fastness of dyed fabrics were equal or higher 3 and 4–5 grades, respectively. Scanning electron microscopy (SEM) images revealed that the P(St-BA-VBT) nanospheres randomly distributed and did not form a continuous film on the cationic cotton fiber surfaces. The X-ray photoelectron spectroscopy (XPS) analysis further demonstrated the presence of cationic nanospheres on the fiber surfaces. The cationic modification did not affect the breaking strength of cotton fabrics.

“…All certain amount of P(St-BA-VBT) nanospheres samples were diluted 2000-fold by deionized water before test. The glass transition temperature of P(St-BA-VBT) nanospheres was characterized by a differential scanning calorimetry (Netzsch DSC 204F1, Netzsch Group, Bavaria, Germany) within the temperature ranged from 20 to 200 °C [24].…”

“…Besides, the size of the nanospheres was significantly smaller than the diameter of the cotton fibers, indicating that the cationization of cotton fabrics had little effects on the spread and diffusion of reactive dye ink droplets on the surfaces of fabrics or fibers [15]. Compared to the previously study [18], the cationization of cotton fabrics modified with nanospheres is an effective method for improving the color performance of reactive dyes ink-jet printing.…”

“…For example, cotton fabrics modified with cationic copolymer nanospheres were dyed by an acid dye, revealing that the dyed fabrics had good handle and permeability [17]. Cotton fabrics pretreated with Poly[Styrene-Butyl acrylate-Acrylic acid-Glycidyl methacrylate] P(St-BA-AA-GMA) nanoparticles had better pigment dyeing properties than the fabrics pretreated with Poly[Styrene-Butyl acrylate-Acrylic acid] P(St-BA-AA) nanoparticles [18]. Fabrics modified with the cationic nanospheres displayed the advantages of high dye utilization and excellent color performance [19,20,21].…”

In this study, the cationic Poly[Styrene-Butyl acrylate-(P-vinylbenzyl trimethyl ammonium chloride)] P(St-BA-VBT) nanospheres with N+(CH3)3 functional groups were successfully synthesized by soap-free emulsion polymerization and applied to different fabrics by pad-cure process. After the pad-cure process, the nanospheres were deposited on the surface of the modified cotton fibers successfully without forming a continuous film structure. The X-ray Photoelectron Spectroscopy (XPS) and the Fourier transform infrared (FTIR) results demonstrated that P(St-BA-VBT) nanospheres were adsorbed on the surface of cotton fibers successfully. The excellent color strength value and outline sharpness of the plain, twill, and honeycomb fabrics can be achieved when the nanosphere concentration, sodium bicarbonate, and steaming time were 1 g/L, 10 g/L, and 6 min, respectively. The plain fabrics exhibited the smallest color strength (K/S) values and the best outline sharpness, followed by twill and honeycomb fabrics, which displayed the largest K/S values and the worst outline sharpness after the same treatment. Besides, all the three fabrics showed excellent rubbing fastness and washing fastness. The cationic P(St-BA-VBT) nanospheres modification of the cotton fabrics provides a novel potential approach to obtain good printing efficiency without affecting the tensile breaking strength of cotton fabrics significantly.

Conventional colored latex particles have poor solvent resistance due to the absence of chemical bonds between the dye and polymer component, resulting in staining and greatly restricting its application. In this research, the disperse dye was chemically bonded to the polymer to prepare covalent and solvent-resistance colored latex particles. Firstly, C.I. Disperse Red 60, as a common disperse dye in industry, was modified by acryloyl chloride (amidation reaction) for the purpose of introducing the C=C bonds. The structure of modified C.I. Disperse Red 60 was confirmed by 1 HNMR, FTIR and elemental analysis and its spectral property was also evaluated. Then the covalent colored latex particles were synthesized via miniemulsion copolymerization of styrene (St) and ethyl acrylate (EA) in presence of modified C.I. Disperse Red 60 monomer. Results of FTIR, TG, DSC and TEM indicated that the covalent colored latex particles were successfully prepared. By using UV-spectroscopy, the solvent resistance of the colored latex membranes in petroleum ether, hexane, cyclohexane, and ethanol was monitored, respectively. Slight change of the absorption was detected for 10 days, which verified the excellent solvent resistance of covalent colored latex membranes. Finally, the prepared colored latex particles were applied on cotton printing in the absence of binder. The results showed that the colored latex particles printed fabric had superior rubbing fastness and soft hand feel.
