ECO-INNOVATION FOR A SUSTAINABLE FUTURE

Eco-innovation is any form of innovation resulting in or aiming at significant and demonstrable progress towards the goal of sustainable development, through reducing impacts on the environment, enhancing resilience to environmental pressures, or achieving a more efficient and responsible use of natural resources. States and governments of the world, different institutions and organizations actively involved and aware in public policies, strategies and actions, reaffirm their commitments and reassess actions in order to achieve a truly sustainable development. In the common vision and the resolutions and other documents of the United Nations Conference on Sustainable Development, Rio+20, the words "environment", "innovation", "green economy" appear very often and almost always along the same context, to achieve the objectives of the sustainable development. The objectives of EU's Europe 2020 strategy for smart, sustainable and inclusive growth, are being implemented through a number of Flagship Initiatives addressing the main challenges, like “Innovation for a sustainable Future - The Eco-innovation Action Plan (EcoAP)”. Eco-innovation Observatory developed the Eco-Innovation index, the first tool to assess and illustrate eco-innovation performance across the EU Member States. Like in all fields, in textiles and leather field, eco-innovation is present and there are a lot of tools available that measure environmental damage and help manufacturers and brands become more sustainable. Eco-innovation is not just a trendy concept but a reality and a necessity nowadays, a way to achieve a sustainable future for ourselves and future generations

Aspect prediction of the knitted fabrics from the yarn properties

The textile technologist knows that the prediction of the aspect of a finished knitted fabric, by the parameters of yarn evenness, does not agree, often, with the reality. There are fabrics, in the market, with irregular aspect, made with yarns in which we have detected few faults. The conventional criteria that are considered in the evenness measuring equipments for the faults detection in the yarns are very limited.In this paper a new evenness of mass index is proposed, denominated deviation rate DR, that, according to it is demonstrated in the experimental stage, it follows an excellent statistical correlation with the aspect of the knitted fabrics.Peer ReviewedPostprint (published version

New Development in the core yarns manufacture

A new mechanism for the regulation of feeding tension of elastic filaments has been developed, in cooperation with a reputable manufacturer of textile machinery, to obtain “core spun” yarns. This device reduces, of a very significant form, the coefficient of variation of the elongation of the yarn and, consequently, the fabrics obtained with this yarns are more regular appearance. This mechanism is fundamental when the new spools of T-400, with diameter and weight superiors to the standard size, are processed.Postprint (published version

SHORT LITERATURE REVIEW ON THE OPTIMIZATION OF THE FIVE-AXIS CNC MACHINES

This paper is a result of a short literature review on the optimization of the five-axis Computer Numerically Controlled (CNC) machine, a first study conducted in a wider research that will be further developed in this field. After a short presentation of these machine tools, are presented some approaches regarding the optimization and virtual modeling of the multi-axis machines

SHORT LITERATURE REVIEW ON THE KINEMATICS AND DYNAMICS OF THE INDUSTRIAL ROBOTS

This paper is the result of a short literature review on the kinematics and dynamics of the industrial robots, a first study conducted in a wider research that will be further developed in the field of the trajectory generating mechanisms of the industrial robots. After an introduction about the importance of the robots in the industrial processes and about the necessity to streamline and optimize the robot`s motion, are presented some recent approaches related to the kinematic and dynamic analysis, the optimization of the robot`s motion, and modeling of the trajectory generating mechanism of the industrial robots

SIMULATED ENTERPRISE - A MODEL OF ENTREPRENEURIAL EDUCATION

This paper shows, after a review of the importance and necessity of entrepreneurial education into current social and economic context, an example or a model for implementation it, namely Simulated Enterprise. The Simulated Enterprise (also known as the Virtual Enterprise or the Practice Enterprise) is a virtual company that runs like a real one. In Romania, simulated enterprises are integrated into a national network of training firms / simulated enterprises, coordinated by ROCT (ROmanian Coordination Centre of Training Firms), affiliated with the EUROPEN-PEN International Practice Enterprises Network. During the period 2008-2015, the evolution of the number of Romanian simulated enterprises was one ascending, and in present students from all programs of study develop activities in the 150 active simulated enterprises, which cover the various fields of activity. There are presented stages of the foundation of the simulated enterprises and the responsibilities of simulated enterprises authorized

NANOTECHNOLOGY IN TEXTILE INDUSTRY [REVIEW]

Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering. Nanotechnology overcomes the limitation of applying conventional methods to impart certain properties to textile materials. There is no doubt that in the next few years nanotechnology will penetrate into every area of the textile industry. Nanotextiles are nanoscale fibrous materials that can be fictionalized with a vast array of novel properties, including antibiotic activity, self-cleaning and the ability to increase reaction rates by providing large surface areas to potential reactants. These materials are used not only as cloth fabric, but as filter materials, wound-healing gauzes and antibacterial food packaging agents in food industry. World demand for nano-materials will rise more than two-and-a-half times to $5.5 billion in 2016 driven by a combination of increased market penetration of existing materials, and ongoing development of new materials and applications. In recent years was demonstrated that nanotechnology can be used to enhance textile attributes, such as fabric softness, durability and breathability, water repellency, fire retardancy, antimicrobial properties in fibers, yarns and fabrics. The development of smart nanotextiles has the potential to revolutionize the production of fibers, fabrics or nonwovens and functionality of our clothing and all types of textile products and applications. Nanotechnology is considered one of the most promising technologies for the 21st century. Today is said that if the IT is the wave of the present, the nanotechnology is the wave of the present, the nanotechnology is the wave of the future

Education and training in Romania on occupational safety and health in the offshore industry

This paper is the result of a study on the current situation in Romania regarding education and training on the occupational safety and health in the offshore industry. This study was conducted within a European project, which, among other things, has as intellectual outputs, identifying the main requirements related to learning needs and competencies and identifying the similar safety and health training courses for offshore industry at European level. Romania has transposed the European Union legislation in the area of minimum requirements for the safety and health of workers in the offshore industry and has an adequate institutional framework aligned to the Community requirements in the field. In Romania, there are no special occupations and explicit requirements for occupational safety and health specialists in the offshore industry. But, there are some training centers, which offer theoretical and practical courses regarding safety and health for those graduates or professionals who wish to pursue a professional career in the offshore industry. Also, some universities provide diplomas, courses or training related to the offshore industry
