Garment Design and Engineering for Hospital Use
Advances in Intelligent Systems and Computing, 2017
Garments used in hospitals play an important role in user's comfort and health. This paper presents the developments of a patented design technology for medical garments aimed at users, caregivers, and health care providers. Traditional gowns lacking comfort and protection affect the patient's dignity. Similarly, patients often use their own garments, which are not designed to provide the best comfort and protection if sensing capacity is affected. Additionally, they can interfere with caregivers' daily tasks. The proposed pajamas consider these needs and allow an effective interaction between patient and caregiver without compromising the person's self-esteem. The selection of functional textile fibers and the use of seamless production processes allow the design of products advantageous in the prevention of wounds and pressure ulcers, as pressure points are reduced and the micro-climate of the skin is managed in a more effective way, enhancing the levels of sensorial, physiological and ergonomic comfort.
Numerical and experimental studies in the development of new clothing materials
WIT Transactions on Engineering Sciences, 2006
In order to enhance the quality and added value of their products, Portuguese industry must react to consumer demands. Amongst the main criteria, thermal comfort is becoming a pressing issue. Such new requirements open new fields in research and development, in which computer simulation plays an important role. In the present work a transient model for heat and mass transfer in a fabric, which is a simplified version of the Gibson and Carmachi model, has been implemented. In order to make the model user friendly, a software application has been developed. This makes it easier to introduce the input data and visualize the results. In parallel, new materials made from natural fibres have been used to produce new knitting. Their thermal properties have been measured in the laboratory and were used to validate the numerical model. The model can be integrated into a wider model for the thermal regulation of the human body. Such a tool could be very useful for designing new fabrics for clothing applications.

Fibres and Textiles in Eastern Europe
In the over-saturated global textile market , consumers have growing expectations towards its goods. The producers who develop new technologies for giving textiles additional functions can gain a considerable advantage in the clothing market. This trend is forcing scientists to inves-tigate new methods of clothing evaluation because present physical-mechanical tests do not guarantee the creation of a multi-faceted opinion on the properties of a textile. One of the new methods applied for clothes investigation was developed at the Institute of Natural Fibres. This method involves the use of electromyographic EMG medical records for the determination of the influence of clothing on muscle activity. The results of the study showed that everyday cloth-ing can be the cause of an increased tendency to tiredness. The aim of the current study was the investigation of the influence of different types of sportswear on the physiological parameters and energy cost of volunteers in sports condit...
Optimizing the protection against the physiological burden of CBRN clothing
International journal of occupational safety and ergonomics : JOSE, 2010
Soldiers can wear chemical, biological, radiological and nuclear (CBRN) protective clothing to be protected against warfare agents. The disadvantage of that clothing is that higher protection introduces higher physiological burden. Therefore an optimum between comfort and protection must be found. Models of all relevant processes were created to find this optimum. The airflow profile around a cylinder with clothing-representing a dressed human body part-was modelled. This flow profile was used for calculating the agent vapour breakthrough through the clothing and for calculating the deposition of agents onto the skin (as indicators for protection). The flow profile was also used for calculating the temperature profile around the body part and the relative humidity underneath and in the clothing (as representative for physiological burden). As a result a tool was created, which can be used to identify the optimum properties of CBRN protective clothing, depending on the intended missi...
Statistical analysis of use-phase energy consumption of textile products
The International Journal of Life Cycle Assessment, 2016
Purpose The purpose of this work was to present a methodology to assess the energy consumption, specifically the energy utilized in the washing and drying processes, of textile products in their use-phase with the help of statistical tools. Regardless of the environmental impacts associated with the use-phase of textile products, analysis of energy consumption in that phase is still lacking. There is a need to design methodology for identifying the hotspots and parameters influencing the energy consumption in the use-phase of textile products. A pragmatic method that consists of a life-cycle assessment (LCA) framework plus principle component analysis (PCA), extended by Procrustes analysis (PA), is used to determine the energy consumption and minimize the possible uncertainties in the use-phase of textile product systems. Methods The LCA plus PCA-PA method employed in this work to analyze the energy consumption of textile products in the use-phase comprises two statistical tools. First, PCA was applied to find the key parameters affecting the results. As an extension of PCA, PA was performed to highlight the most prominent variables within the dataset and extract the maximum amount of information. Lastly, hierarchical cluster analysis (HCA) was utilized for the classification of textile products on the basis of energy consumption variables and the similarity of their results. Results and discussion Among various energy consuming parameters in the use-phase of a textile product, both geographical and physical aspects can be prominent variables that significantly can affect the results of the energy consumption. After the LCA plus PCA-PA methodology, country of the use-phase in the geographical aspect and in the physical aspect, the fiber type and weight of the products were the influential variables. Hotspots or influential parameters being identified, a number of steps can be taken that can play an important role in decreasing environmental impacts by reducing the energy consumption in the laundering process of textile products during the use-phase. Conclusions The methodology of LCA plus PCA-PA for energy consumption in textile products was employed to study the gap in currently available assessments. Using this method, the main influencing energy consuming parameters or hotspots in the use-phase of a textile product system could easily be identified and potential improvements of sustainability can be proposed.
