Extensive efforts have been made in the research and development of smart textile systems in recent years. One of these developments in smart materials is shape memory applications. Shape memory materials (SMM) are smart materials that can remember and recover substantial programmed deformation upon activation and exposing to an external stimulus such as chemicals, temperature, pH, light, a magnetic field, etc. Shape memory materials have been used in many areas and textile application of this technology has covered a wide usage recently. Today's textile concept isn't the similar to past and expectations of people from textile have been changing more and more. In this point, shape memory materials can answer these needs in textile due to its smart features. Shape-memory materials can be used in textile as clothing, yarn and fabric. The application possibilities are only limited by our imagination and creativity, so shape-memory productions have been able to gain a different aspect to textile.

It has been seen great advances in technology in recent years. One of these advances has become in smart textile. Although there are many different definitions, usually smart textiles can be defined "sense and respond to environmental stimuli". They have been different application areas such as e-textiles, nano textiles, technical textiles, etc. In the last decades, e-textiles developments come to the fore in the smart textiles. E-textiles contain some digital, electronical circuits, sensors and textile based materials such as conductive fiber, yarn and fabrics. A lot of products can be made in this industry but the effects of environmental stimulis such as human perspiring on these products are not examined so much. In this study, it was examined the conductivity of e-textile fabrics in the changing different pH values according to gender. Acidic and alkaline solutions have been applied on conductive fabrics and results have been examined with SEM and resistance measure. As a result of the study, it is found that perspiration doesn't affect the conductivity on conductive textile surface badly. In contrast, conductivity has the better result when perspiration solution used. Conductivity increased for each pattern and pH solutions because of decreasing resistance.

In this study, Yemeni, a traditional clothing product of Kahramanmaraş province, was investigated. Meetings were held with the masters who made this craft. Kahramanmaraş yemeni is a product of articulation of art, which has its roots in the past. The most important feature that distinguishes yemeni from traditional shoes is that only leather material is used in its production. The fact that the product is made entirely of leather material supports the sustainable product design. Leather material is not used as it is when it is turned into a product. In this study, in the first part of the experimental study involving the artisan, industrial products designer, and textile and fashion designer, interviews were realized with the leather master and information about the leather used in the production of lemons and lemons was collected. In the second part, in accordance with the information provided by the leather craftsman, abrasion resistance and rubbing-related colour fastness tests were performed on the wet and dry conditions of the leather tanned leather with
