Abstract
Polyester/carbon (PET/CAR) blend fabrics were prepared by treating polyester/cotton (PET/COT) fabrics with dilute phosphoric acid at high temperatures to carbonize the cotton fibers in the PET/COT fabrics. Fourier-transform infrared, X-ray diffraction, and thermogravimetric analysis results were in accordance with the carbonization of cotton fibers. The surface morphology images showed only slight etching was on the polyester fibers and the fibers structures almost remained intact. The PET/CAR fabrics exhibited excellent antistatic properties. The induced voltage and half-life of the PET/CAR fabrics treated with 5% phosphoric acid solution were close to 0 V and 0 s, respectively. The ultraviolet protection factor value of the fabric treated with 5%-phosphoric acid reached 243 ± 8. The emergency recovery crease angle and the slow recovery crease angle reached 222 ± 4° and 230 ± 2°, respectively. The light shielding properties of PET/CAR were also superior. The tensile strengths of the PET/CAR fabrics decreased; regardless, the PET/CAR fabrics remained adequately strong for many applications such as blackout curtain, agricultural greenhouse shading textile and anti-UV umbrella textile etc.
