Evaluation of Comfort Attributes of Polyester Knitted Fabrics Treated with Sericin
R. F. El-Newashy,S. Mowafi,K. Haggag,M. Abou Taleb,H. El-Sayed 한국섬유공학회 2019 Fibers and polymers Vol.20 No.9
This work was adopted to study the effect of sericin-containing bath on the different structures of knitted polyesterfabrics to improve some of their comfort attributes. Without appreciable deterioration in its inherent properties, the differentstructures of treated polyester fabric exhibited induced hydrophilicity, enhanced electrical conductivity, improved resistanceto ultraviolet radiation and better water vapour permeability. Five knitted polyester fabrics of different structures weresaponified by sodium hydroxide to create carboxylate ions along their macromolecules, and then treated by sericin withinfreshly discharged bath from degumming of raw natural silk. Treatment of polyester fabrics with sericin was carried out inpresence and absence of glutardialdehyde as a crosslinking agent between polyester and sericin macromolecules. Differentthermo-physiological parameters of comfort; namely thermal conductivity/resistivity, air/water permeability, release ofelectrostatic charges, ultraviolet protection factor, and water vapour transmission of the sericin-treated as well as untreatedknitted fabrics were assessed. The mechanism of interaction between knitted polyester fabric and sericin in presence ofglutardialdehyde was proposed. Scanning electron microscopy was used to ascribe any alteration in the fibre morphology. The change in the fabric crystallinity was investigated using X-ray diffraction pattern. The burst strength, bending stiffnessand yellowing index of the treated fabrics were in the acceptable range.
