The fabrication and characterization of casein/PEO nanofibrous yarn via electrospinning

Abstract

Casein, a natural protein, has been used as a biopolymer-based resource for producing fiber. This fiber provides high comfort properties with a pH close to human skin. This study focused on evaluating the production feasibility of casein nanofiber twisted yarn with the highest protein content in the hybrid yarn, obtaining suitable spinning conditions and desirable properties of the produced yarn. The desirable yarn achieved by composing 90% casein and 10% polyethylene oxide. The yarn strengthened using several types of cross-linking methods and the best technique was obtained to spin an optimized engineered yarn. Consequently, the biodegrading test conducted on the optimized yarn (90% casein and 10% polyethylene oxide blend) in the presence of 40% di-isocyanate as strengthener additive. Observations showed that after ten days, the sample mostly degraded in the solvent and its strength massively reduced so it could be considered as an environmentally friendly, biodegradable fiber.

Cross‐linked electrospun polyvinyl alcohol/sodium caseinate nanofibers for antibacterial applications

“…It exists in both water-soluble and water-insoluble forms. [19,20] Due to these properties, casein is a suitable candidate for biomedical applications. In addition, it has many applications as coating, adhesive, and packaging materials in the paper, leather, textile, and food industries.…”

“…The cross-linking of PVA reduces the hydrophilicity of the membrane and provides a resistant support network for the immobilization of biomolecules. [16,17,19] Therewithal, GLA is by far the most widely used chemical agent for SC cross-linking due to its high efficiency in stabilizing protein-based materials (particularly collagen, and casein). [23] In the study of Huang et al, casein cross-linked with GLA was used to cover magnetic particles.…”

New Insights toward Casein/Polyvinyl Alcohol Electrospun Nanofibrous Webs as a Piezoelectric-Cum-Triboelectric Energy Harvester

“…For instance, the peak at 3297 cm –1 corresponding to the −OH group of the PVA polymer has found to be shifted to 3285 cm –1 . From this shifting behavior of the peak for the casein/PVA blend materials, it can be hypothesized that there are some interactions which can take place between the casein molecules and PVA polymer chains. , For better understanding of the presence of various functional groups in the casein molecule, the chemical structure is presented in Figure c.…”

Integración de biopolímeros en la Industria Textil

“…Las fibras que provienen de proteínas regeneradas se encuentran dentro de la clasificación de fibras artificiales. Estas fibras tienen un parecido con la lana, su uso generalmente se ha combinado con otros biopolímeros o con fibras naturales, como el algodón y la lana, se caracteriza por tener propiedades similares a las de la lana, con una mayor sensibilidad a condiciones alcalinas, y se hincha debido a su alta solubilidad en agua; también presenta una resistencia a la tracción que afecta directamente sus propiedades mecánicas (Minaei et al, 2019).…”
