The purpose of this study is to investigate the utility of carbon black containing coating formulations that are conventionally used for pigment printing of textiles in fabricating electrically heated fabrics.

Specifically, electrical and thermal characterisation of the coating system was carried out to establish the feasibility of the system for use in the manufacturing of flexible heating elements on textile substrates. The coating formulations were applied via a simple padding technique followed by stitching the electrodes using a conductive yarn.

The heating elements of different sizes thus produced showed Ohmic behaviour as a resistor and attained a targeted temperature difference of up to 40°C within the applied voltage range. A prototype heater was also produced, and thermography results showed uniform heating and cooling of the heater that was incorporated into a jacket.

The proposed method is envisaged to be very practical for the realisation of completely textile-based heating elements of different shapes and sizes. Furthermore, the proposed manufacturing method can be used to convert conventional ready-made articles of clothing into heated textiles for various applications.

Operationnal excellence has emerged as a critical factor for organisations competitiveness. Companies in developing countries are striving to elevate their operational performance to new heights. This study aims to explore the effective best practices, drivers and challenges to operational excellence in North African business.

To address the objectives of this study, a qualitative approach is adopted. A total of 13 experienced professionals holding leads initiatives within North African enterprises are surveyed. Following, content analysis method is employed to extract, categorise and analyse the knowledge from the interviews.

The findings indicate that the implemented best practices include process optimisation, performance measurement, standardisation, customer-centric approach, lean manufacturing and total quality management. For a successful adoption, the results shed light on the importance of leadership commitment, upskilling, digitalisation and employee’s empowerment. However, the implementation faces several challenges incorporating unsustainable engagement, resistance to change, disconnected practices, insufficient investment, deficient improvement assessment and limited access to digitalisation.

This study contributes to exploring the best practices, enablers and barriers to successful implementation of operational excellence in emerging economies. Its findings can be used by scholars and decision-makers to advance knowledge around operational excellence, broaden the existing strategies to tailor specific contexts and promote operational performance.
