In this study, we fixed silk sericin in fabrics as a finishing product. First of all, we have extracted sericin from silkworm cocoons in order to obtain the optimum yield of sericin that is not denatured. For this reason, we have searched the optimum parameters for a favorite sericin extraction. Then, the sericin extracted was fixed onto wool and cotton fabrics in an aim to modify some of their properties. The tests of treated fabrics showed that sericin has an affinity for wool, whereas it does not have it for cotton. This affinity for wool fiber was obtained in defined conditions with about 48% exhaustion rate for a sericin concentration of 2.5% (w/w). Compared to different sericin concentrations (0%, 2.5%, 5%, 10% and 20%), a 5% of sericin (w/w) improved the wool samples touch until a score of 4 points, as well as the water's absorption with a profit of 70.75%. The samples also showed an improved antibacterial activity. © 2012 Copyright The Textile Institute.

The objective of this study is to predict the mechanical behaviour of fabrics in uniaxial tensile using only their technical parameters. To achieve this objective, it was necessary, in first stage, to develop a model which can simulate this fabric mechanical behaviour. A modified form of a rheological model is used to describe the mechanical behaviour of fabrics in uniaxial tension. The proposed analytical model can fairly well replicate the behaviour of fabrics during relaxation and simple traction. In order to characterise the coefficients of this model, simple uniaxial tension and relaxation tests were performed for 29 fabrics in the warp and the weft directions. A retro-propagation algorithm is applied in training the artificial neuronal network, which performs a functional mapping between these mechanical coefficients and the technical parameters of fabric. This allowed us to predict the mechanical behaviour in tension and relaxation of fabrics starting only from their technical parameters. © 2010 The Textile Institute.

Natural fibres present multiple characteristics and are used in many fields such as textiles, technical or medical applications. In this context, we tried to use ligno-cellulosic fibres extracted from esparto (Stipa tenacissima L) as a support fiber in hygienic products. Due to their cellulosic nature, esparto fibres can provide a certain water sorption potential. In fact, fluff pulp was always used as a support fibre in the absorbent core structure of many hygienic products and this is particularly after adding super absorbent polymer (SAP). In this study, we choose to optimise the extraction process of these fibres using an experimental design method in order to obtain ultimate fibres and maximise their absorbent properties (absorbent capacity and retention). © 2010 The Textile Institute.

Polyamide 6.6 fibres were modified for the improvement of dyeing affinity using a graft copolymerisation method. These fibres were grafted with acrylic acid as monomer. The influence of the chemical modification of polyamide 6.6 fibres on the dyeing properties was investigated using a cationic dye (Red Astrazon5BL). It was shown that the dye uptake of the modified fibres was greater than that of the unmodified fibres. The kinetic study of the cationic dye used at various grafting percentages showed an improvement of the dye build-up rate, such as its exhaustion. In addition, an increase in the adsorption of the dye quantity fixed on the surface layer of the fibre made up of the grafted molecules was announced. Colour fastness to washing was improved with the grafting percentage. The modelling of the adsorption isotherms using Langmuir, Freundlich and Jossen relations allows the determination of isotherm constants. The results obtained from this modelling study show the existence of several models corresponding to various percentages of grafting. © 2012 The Authors.

We can enhance our quality of life and reduce environmental impacts by making improvements in textile product design. By thinking about the environment when we design, choose and use technology, we can play an important part in building a better world for the future. If we are going to live in a sustainable way, the technology that we use has to be sustainable. This paper provides an insight into how the design of textile products could provide for a more sustainable future. It describes a design concept for an ecological relaxing textile that uses photovoltaic cells to collect and store solar energy and to power an electronic relaxing system. This design may help improve our quality of life now and in the future. The raw materials and processes, the electronic devices and the dimensions of solar energy for this application are analysed from an environmental perspective. The solar relaxing textile can facilitate our daily life by providing increased comfort and well being, and also acts as an indirect message to use renewable energy within textile support, in order to preserve our ecology. © 2010 Taylor & Francis.
