This research studies the properties of a plain knitted fabric made from cotton/T-400 ring core spun yarn and 100% cotton ring spun yarn. Properties of plain knitted fabric made from 100% cotton ring spun yarn were compared with one made from cotton/T-400 (70.4C/29.6T). We focused on knitted fabric properties such as the bursting strength, elongation at break, tensile strength, air permeability as well as pilling properties. The two yarn samples were produced on the ring frame which had a special attachment for core spun yarn. Fabrics were then knitted using a circular machine, for consistence of results plain knit structure was adopted for all samples. Knitted fabric properties were then tested and results statistically analyzed. Research results show that, plain knitted fabrics made from cotton/T-400 (70.4C/29.6T) ring core spun yarn exhibit better elongation at break, bursting strength and air permeability. Whereas the fabric made from 100% cotton showed better pilling resistance and tensile strength compared to cotton/T-400 (70.4C/29.6T) plain knitted fabric. Results show that T-400 filament has very significant influence on resulting fabric properties and hence can be technically manipulated to suit different fabric end use requirements. © 2014 WILEY-VCH Verlag GmbH & Co.

The activated carbon was prepared from eggplant stalk by activation of zinc chloride. The optimum conditions were obtained by using the orthogonal experiment method. Porosity characteristics were determined from the analysis of N 2 adsorption isotherms using both BET and Langmuir equations as well BJH method. The surface functional groups were analyzed by using a FT-IR spectroscopy. Microstructure of the sample was examined using a scanning electron microscopy (SEM). The results show that the best sample of activated carbon is obtained under the conditions : the impregnation ratio of 2; impregnation time of 8 h; activation temperature of 550°C and activation time of 60 min.The iodine adsorption value and methylene blue adsorption value of the prepared activated carbon are 1270.06 mg/g and 17.4 mL/g, respectively. And the activated carbon developed possesses a large apparent surface area (S BET=1649.615 m 2/g, S L=1851.649 m 2/g) and high adsorption pore volume (V=0.488 cm 3/g) with average pore size diameter of 2.241 nm.
