Ink droplet spreading on fabric determines the printing accuracy of ink‐jet printing, and fabric pretreatment greatly affects the ink droplet spreading. In order to reveal the relationship between fabric pretreatment and printing accuracy of reactive dye ink on silk fabrics, the fabrics were pretreated by urea and sodium alginate to control the ink droplet spreading. Results showed that droplet spreading was influenced by surface energy, water absorbing capability and capillary distribution of the pretreatment agent on fabric surface. Urea acted as a moisture‐absorbing agent accelerating the migration of ink from the pretreatment paste to the silk fibers. Final diffusion image and diffused area of droplet on the pretreated fabrics were also investigated. The final image of droplet deposited on sodium alginate and urea pretreated fabrics were circular shape and crisscross shape, respectively. Compared with untreated fabric, results clearly demonstrated that sodium alginate could restrict the droplet spreading due to the diffused area reduced from 85 mm2 to 47–58 mm2. Moreover, urea and sodium alginate as the pretreatment agents were applied on ink‐jet penetration printing. The penetration printing exhibited good printing accuracy, and the color performance and printing accuracy almost the same between obverse side and reverse side of the printings. © 2018 Wiley Periodicals, Inc.

“…The Review does not explicitly cover application of the aforementioned techniques in sterilization, but it does acknowledge techniques that are routinely used for sterilization and provides appropriate references to publications that have systematically studied the effects of these techniques on sterilization of silk materials. A major body of work also describes the use of dry surface modification techniques in the textiles industry for applications such as improvements in dye uptake , and wickability. , While information on changes to silk is drawn from these studies, their applications will not be explicitly discussed, as the current Review focuses on biomedical applications of silk.…”

Silk-based materials are widely used in biomaterial and tissue engineering applications due to their cytocompatibility and tunable mechanical and biodegradation properties. Aqueous-based processing techniques have enabled the fabrication of silk into a broad range of material formats, making it a highly versatile material platform across multiple industries. Utilizing the full potential of silk in biomedical applications frequently requires modification of silk's surface properties. Dry surface modification techniques, including irradiation and plasma treatment, offer an alternative to the conventional wet chemistry strategies to modify the physical and chemical properties of silk materials without compromising their bulk properties. While dry surface modification techniques are more prevalent in textiles and sterilization applications, the range of modifications available and resultant changes to silk materials all point to the utility of dry surface modification for the development of new, functional silk biomaterials. Dry surface treatment affects the surface chemistry, secondary structure, molecular weight, topography, surface energy, and mechanical properties of silk materials. This Review describes and critically evaluates the effect of physical dry surface modification techniques, including irradiation and plasma processes, on silk materials and discusses their utility in biomedical applications, including recent examples of modulation of cell/protein interactions on silk biomaterials, in vivo performance of implanted biomaterials, and applications in material biofunctionalization and lithographic surface patterning approaches.

This study focuses on changing the surface properties of raw silk fibers to simplify the degumming process. Because the conventional degumming processes may be harmful for fibers, they must be applied moderately. Utilizing the novel techniques and technologies, researchers are trying to find alternative ways in order to achieve effective sericin removal without damaging the fibroin part of the silk. In this study, one of the novel technologies, low-pressure plasma technology was used to remove sericin layer by etching. Air, oxygen and water vapor plasmas were applied to raw silk fabrics under different time and power conditions. Weight loss, breaking strength, scanning electron microscopy and fourier transform infrared spectroscopy-attenuated total reflectance were used to characterize the effects of plasma treatments.
