In this study, fabrics which are made of flame resistant cotton, Nomex, polybenzimidazole （PBI）, polysulfonamide （PSA）, kermel, and blend of kermei with rayon fiber are investigated on high intensity of different radiant and convective heat source. The mechanism of heat transfer in different situations is discussed. It is identified that exposed candition has an important effect on thermal protective performance. TPP rating increases with the increasing percentage of convective heat.展开更多

By means of measuring and analyzing the fiber's diameter, linear density, diameter coefficient, thickness and fullness, this paper focuses on the influence of dilative technology on tussah silk's fiber and fabric. The results include the following three aspects: the diameter coefficient of dilative tussah silk fiber is increased by 10.35%, dilative tussah heather silk is thicker and fabric fullness is improved by 9%.展开更多

Its results show that the improvement of provincial textile industry labor productivity has mainly resulted from technical progress since 2003. Meanwhile, labor productivity of underdeveloped provinces has been growing faster than that of developed ones owing to technology diffusion. And then, the above-mentioned improvement has originated from the enhancement of capital deepening and technology efficiency. In addition, scale return of capital per labor appeared to decrease during the period from 2004 to 2005.展开更多
