“…Obviously, for the cyan, magenta, yellow, and black block with a filling rate of 100%, at the maximum absorption wavelength (λ = 670, 550, 430, 590 nm), the honeycomb weave fabrics possessed the greatest K/S values, whereas plain fabrics exhibited the smallest K/S values due to the honeycomb fabric having the least interlacing points of warp and weft, maximum roughness, porosity, and thickness. The capillary pores between the fiber and fibril let inks diffuse into the interior of the fabric and even permeated into the amorphous areas of the fiber by hydrogen bonding as well as capillary pressure, resulting in most dyes being immobilized on the front of the fabric. , The color of printing fabric is defined by the light source, light reflection, absorption, scattering, transmission, fabric, and observer . The distribution of dyes immobilized on the fabric greatly affected the absorption and reflection of light.…”

“…As a result, the plain fabrics displayed the lowest color strength and the optimal pattern sharpness, and honeycomb fabrics exhibited the highest color strength and the worst pattern sharpness. Because honeycomb fabrics had the maximum roughness, porosity, and thickness, the capillary pores between the fibrils, fibers, and yarns made it easy for inks to diffuse into the fabric under the action of hydrogen bonding and capillary pressure and even penetrate into amorphous regions of fibers, leading to more reactive dyes being immobilized on the front side of the fabric. , Because the formation of the apparent color of the inkjet printing fabric is not premixed, the fabric and various color ink droplets are selectively absorbed and reflected by the light irradiated on the fabric as needed, the inkjet-printed pattern is presented by mixing colors on the fabric. Therefore, the inkjet-printed patterns mainly were decided by the precise distribution of ink droplets on fabrics .…”

The porosity, roughness, and thickness of woven fabrics limit inkjet printing quality, which is extremely important for obtaining high-quality inkjet printing images on fabrics. This study reveals the application of poly[styrene-butyl acrylate-(P-vinylbenzyl trimethyl ammonium chloride)] nanospheres prepared via a soapfree emulsion polymerization approach as a novel kind of the cationization modifier for the inkjet printing of different woven cotton fabrics by the pad-cure process. It was found that the nanospheres exhibited an average diameter of 65.5 nm, a zeta potential of +57.8 mV, and a glass transition temperature of 94.7 °C. The nanospheres deposited on three cotton fabrics through the dip-rolling process, resulting in the increase of zeta potential, hydrophobicity and thickness of the fabric, and the decrease of porosity and roughness. The high-quality inkjet printing images can be obtained on fabrics with different structures owing to the differences in zeta potential, hydrophobicity, porosity, roughness, and thickness of fabrics. The plain, twill, and honeycomb weave fabrics obtained high-quality inkjet printing images for portraits, oil paintings, and landscape paintings, respectively. The nanospheres could strongly adsorb on the fiber by electrostatic attraction. The reactive dye molecules in the inks could react with the cationized fibers by electrostatic attractive force, resulting in the increase of the color strength, fixation rates, and outline sharpness. The nanosphere cationization of different woven fabrics offers a new potential method for obtaining high-quality patterns without significantly affecting the fabric handle.

“…Figure 8 shows the contact angle on six different fabrics as a function of time for 60 s. While impacting the porous substrate, the polyurethane droplet tends to spread and penetrate into the fabric surface. 28 Table 3 lists the contact angle and its evolution time of the dynamic contact angle. The results show that all of six woven fabrics are hydrophilic, and the contact angle of the fabric increases due to the addition of the finishing agent.…”

Effect of the basic surface properties of woven lining fabric on printing precision and electrical performance of screen-printed conductive lines

Conductive lines are essential for the integration of electronic devices into fabrics, and their direct screen printing on fabrics is a promising, simple and low-cost method for mass-manufactured textile-based conductive lines. However, the intrinsic porous structures and texture characteristic of textiles complicate the diffusion and penetration of conductive ink, and will deteriorate the printing precision and electrical performance of conductive lines. To establish the relationship between the surface characteristics (i.e. porosity, roughness, contact angle) and printing precision as well as electrical performance, the screen-printed conductive lines on six different nylon woven lining fabrics were examined and compared. Moreover, to study the printing precision and the minimum printable line width on woven lining fabric, conductive lines with different widths were screen printed. The results showed that the fabric substrate with the smallest pore size and roughness shows a higher printing precision and lower electrical resistance of screen-printed conductive lines. Relatively, the dynamic contact angle and wetting time of ink on the surface of the fabric have a significant effect on the printing precision. Therefore, the surface structure of the fabric substrate determines to some degree the printing precision of conductive lines, the printable minimum line width and its electrical properties. It is believed that these findings will provide some important support for screen printing flexible electronic devices on woven textiles.

“…Combined with Figure 4 and Table 1 analysis, the reason was that the warp and weft interlacing points of twill fabrics were less than those of plain fabrics, and the warp roughness, weft roughness, fabric thickness and porosity were larger than those of plain fabrics. The gaps between the yarns, fibers and fibrils made the inks more easily diffuse into the fabric interior and penetrate into the amorphous region of fibers with the help of the capillary pressure and hydrogen bonding, which contributed to most of reactive dyes being fixed on the fabric surface [33,34,35]. The color of ink-jet printed fabric is determined by the light source irradiation on the fabric and the light absorption, reflection, transmission, and scattering of the fabric and observer together [35].…”

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.
