Vishnoi Prashant,Ishtiaque S. M.,Das A. The Korean Fiber Society 2005 Fibers and polymers Vol.6 No.3
The present paper is concerned with the influence of opening roller speed, drum speed difference and suction air pressure on properties of polyester and acrylic open-end friction spun yams. The results shows that the opening roller speed and the suction air pressure have considerable influence on the characteristics of polyester and acrylic open-end friction spun yams. In case of polyester yams the unevenness, imperfection and hairiness decreases and the yam tenacity increases with the increase in opening roller speed and suction air pressure. However for acrylic yams the unevenness and imperfections decreases and tenacity increases with the increase in opening roller speed and suction air pressure.

Multifunctional and durable nano-coating of titanium dioxide (TiO2) on cotton and silk fabric surface has been achieved via sol–gel method in aqueous medium at room temperature. The nanosol is coated on fabric surface by pad-dry-cure method using 1% acrylic binder to achieve durable coating. The coated fabrics are characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray powder diffractometry (XRD), optical microscopy, and scanning electron microscopy (SEM). The performance of the coated fabrics against self-cleaning efficiency and UV protection is evaluated. The self-cleaning efficiency is assessed against the artificial stain of Schezwan chutney, coffee, Coca-Cola, and turmeric. Maximum stain removal efficiency is achieved with coffee stain with 81.25% and 96.63% for cotton and silk fabrics, respectively, after exposure to 20 h of sunlight. However, tensile strength and elongation of the coated fabrics decrease after the exposure to sunlight. The average size of the TiO2 particles formulated in the nanosol is found to be about 5 nm which is sufficient for scattering the UV radiation from the textile surface. The self-cleaning effect and UPF of nanosol-treated silk fabric are found to be better than that of cotton fabric. UPF of treated cotton and silk fabric is found to be 53.87 and 61.79, respectively.
