It would be uncertain if, in fact, textile technology in Congo-Kinshasa has not followed the evolution of clothing over time. The loincloth is a piece of clothing that corroborates a culture based on the civilization of a people. This fabric represents respect for certain texts linked to morality in women as well as in men. For the Congolese woman, the loincloth represents a textile technology which vibrates to the rhythm of creation and production of models which constitutes the ingenuity of the couturier artists in a workshop. This study is part of the impact of textile technology for holding cultural-ethnic events, in particular: national holidays, customary weddings, prayer evenings, gala evenings, etc. Thus, the persuasive theory (BARABARS H., 2009) provides a favorable view in the semiology of clothing communication on the need to dress Congolese women in loincloths. This theory is linked to the mechanisms of cognition through the abstraction inherent in the idea and the notions learned in thought. In experimental psychology, in humans, we distinguish scales of conscious and unconscious perceptions, also called implicit or subliminal. This distinction has been extended to other animals to the extent that it is recognized or, to another extent, can be trained and conditioned to indicate whether or not they have perceived a stimulus. Fashion offers its non-inevitability for the maintenance of the textile and clothing industry. This theorization relating to persuasion appeals to the senses, the mind, ideas, the moment and time for clothing fashion. It is sensory and "immediate" as the senses deliver direct information, and reverberate in people's culture on respect for the morals and customs surrounding an evening or a festive event. Thus, through surveys carried out in Kinshasa, this study will focus on the necessity of women's clothing in loincloths and its impact in Congolese culture.
