Description

The standard carbon black used for the preparation of artificially soiled cloths in the detergency test is an industrial product being sold for other uses, therefore, this has some disadvantages in such as; the change of its quality and the cessation of its production sometimes occuring according to the change of its market requirement.<BR>However, the standard carbon black for the artificially soiled cloths requires constant and higher uniformity of the quality. This study was purposed to prepare the suitable carbon black by laboratory method.<BR>In the first step the authors, investigated the effects on soiling and detergency of cloths by the following factors of carbon black as a basic study; structure, particle size, specific surface area, oxygen-containing groups on the particle surface, oily matter of carbon black. In order to evaluate the individual effect of these factors authors paid much attention to obtain the carbon black with same quality. As the usual carbon black has different quality authors treated it by suitable method or prepared new carbon black specially in case of need. From these studies the following results were made clear; 1) All of above mentioned factors were influential on the nature of the soiled cloths. 2) Suitable amount of oily matter on the particle surface was necessary factor. Uniformity of particle size and low chain structure of carbon was desirable factors.
