Combinative Scouring, Bleaching, and

In order to facilely achieve pretreatment and salt-free dyeing of greige knitted cotton fabrics, a combinative scouring, bleaching, and cationization pretreatment of the fabrics is designed in this study. The fabrics are first treated in a bath containing commercial scouring and bleaching agents, and then glycidyltrimethylammonium chloride (GTA) is directly added into the bath to achieve Method of improving the brightness of calcium A method of improving the brightness of calcium carbonate filled paper. The filled paper is dried and then bleached with an aqueous solution of a bleaching agent. The process may be used on all grades of paper that contain filler and is particularly useful in the bleaching of low brightness grade papers that are produced from mechanical pulp that contain calcium carbonate.

The chemicals used for improving the whiteness of fabric are known as bleaching agents. Although several bleaching agents are available, hydrogen Laccases to Improve the Whiteness in a This study reports for the first time on the enhancement of the bleaching effect achieved on cotton using laccase enzyme.

Kossatz et al. (20) found that the addition of calcium compounds to bleaching gels can help prevent mineral loss and the reduction in microhardness of the enamel caused by the bleaching process, thereby reducing sensitivity. Moreover, calcium compounds maintain a
