Negative Ion Release of an Anion PP Fiber Covered Colored Cotton Textile

摘要

The negative ion release properties of an Anion PP fiber covered colored cotton textile were tested at different washing times and at the same time microstructures of an Anion PP fiber covered colored cotton textile yarn were analyzed by scanning electron microscopy (SEM). Before washing the static negative ions number of the textile was averagely 2884 per cubic centimeter and its dynamic negative ions number was 3084 per cubic centimeter on average. After washing 50 times the static and dynamic negative ions number of the textile was separately 2614 and 2398 per cubic centimeter. SEM microscopy analysis displayed that it was little that washing effect on the release of negative ion which still could meet the needs of people of anion.
