R&d of permanent flame retardants anchored superficially at the nanoscale.

Development of new flame retardant chemicals capable to functionalise fabrics of different nature, without altering the properties of the textile and just making use of the optimal quantity of that product, and simultaneously reducing the environmental impact.

The main objective is to develop an innovative product to provide FR properties to fabrics, mainly cotton and cotton-polyester fabrics, with the minimum quantity of FR chemicals. Instead of introducing big amounts of FR into the fiber structure through chemical reactions, it is pretended to incorporate fairly quantities to achieve the self-extinguishing behavior, without environmentally harmful FR. To reach the optimal flame retardancy it is necessary resort to innovative technologies which affect only the fiber surface without altering the desired properties, as for instance: grafting, silanizing, cationizing, nanolinking, and so on. After its study and research, it will select the most effective one for each type of tissue and it will apply by conventional techniques, as washing, foulard, sucsosa, ramo de agua, polimerizadoras, contact cylinders “kiss-roll”, and so on. Specific objectives include the following ones: TECHNICAL OBJECTIVE: Investigation of a new FR product which only affect to the fiber surface when applied. This new product will modify the superficial layer making it more reactive and facilitating the linking process of the FR components. The mechanisms, which are going to provide the superficial activation, are very innovative and act on the molecular level, in the nanometric scale, and for that, are a very relevant point of the development. Those which are going to be studied are: grafting, silanizing, cationizing, nanolinking. The flame-retardant durability is another parameter to be considered during the project, since the functionality must be maintained for a long period of time, which implies that the mechanism of crosslinking the compound to the fiber FR has to be permanent. Thanks to the flame-retardancy provided only in the surface, the fabric will keep all the cotton or cotton/polyester characteristics and initial properties, since the content is not going to be modified by the FR finishing treatment. ENVIRONMENTAL OBJECTIVE: We aim to achieve a considerable reduction of the chemicals used in the flame retardant finish, applying just the optimal quantity to attain the desirable effects. As a result, the amount of waste generated will be reduced as well as all its associated problems. Moreover, the flame retardant is going to be constituted by eco-friendly chemicals (phosphorous chemicals) which don’t pose a problem for the environment (halogen free). It must be highlighted that the products are going to be applied with conventional textile equipment and machinery, so the introduction of the innovation is not going to entail any renewal of machinery, and any waste is going to be produced as a result of that. MARKET OBJECTIVE: The market objective is based on developing new functionalized products for FR treatment for applying on the textile substrates to provide FR properties with the minimum quantity of chemicals, at competitive prices which will give an important added value in the market, which is also a strategic objective within the textile sector. The target of this development is to launch to the market a FR chemical for textile applications with such an unique properties that will differentiate form the competition. It will mean going further in the nanotechnology field, but based in innovative crosslinking mechanisms.
