Title

Effect of storage and bleaching of cotton fiber pulp on the stability of bond paper optical properties

Pages

  217-227

Abstract

 The aim of this study was to investigate the effect of storage and bleaching of cotton pulp on stability of optical properties of bond paper. Industrial unbleached cotton pulp with the freeness 13° SR, in two types of static and agitating storage was stored for 3-15 days in room temperature and the pulp was bleached with hydrogen peroxide. Then, standard handsheets were made from bleached pulp and after air-drying, the sheets were aged by UV and thermal methods and their optical properties measured. Results showed that agitated samples had higher brightness and whiteness and lower yellowness than static ones and by increasing of storage time this numbers be much and less, respectively. In case of UV treated samples, the brightness and opacity of static samples decreased and agitated ones increased. The brightness of static and agitated samples with thermal treatment showed up and dawn trend, respectively. Also, UV and thermal treatments, especially in static samples lead to much yellowness and much whiteness in agitated ones. Therefore, agitated storage method was better than the static one to provide suitable optical properties before and after bleaching. In addition, paper made from agitated storage samples had more desirable characteristics and the influence of temperature was more than UV in immediate and longtime.
