Self cleaning textile fabrics

自清洁纺织面料的发展，用于制造服装，外套，室内装潢（包括家具）和休闲面料，是为了走向理想的情况下，需要最少的洗涤，护理和维修的纺织面料。赋予服装和织物的这些属性与生态设计有关，而自洁概念最终会大大延长使用寿命，减少洗涤/护理，肥皂消耗和洗涤所需的能源。对于消费者和企业买家来说，这将意味着可观的节省。对社会而言，最少的清洁/护理意味着能源成本的降低、环境的改善和水污染的减少。众所周知，反复洗涤会加速服装和织物的老化或变质。传统的洗涤和干燥过程会对织物和衣物造成不同的机械、物理和化学损伤。干洗就没那么苛刻了；然而，它需要污染和挥发性化学品，如全氯乙烯，是有害挥发性有机化合物（VOC）的重要来源。反复洗涤引起的损伤可能包括抗拉强度、抗撕裂性、尺寸稳定性和颜色变化等方面的损失。我们将采用不同的策略来获得自清洁性能：我们将开发基于光催化氧化的新功能化学物质用于纺织品整理配方，我们也将设计原始的纺织品表面设计来模仿莲花效应。

The development of self cleaning textile fabrics, used to manufacture garments, outerwears, upholstery (including furniture) and casual fabrics, is proposed in order to move toward the ideal situation where minimal washings, care and repairs are needed for the textile fabrics. Such attributes confered to garments and fabrics are relevant to ecodesign, while the self-cleaning concept leads eventually to dramatic extension of the lifetime, reduction of washings/care, soap consumption and energy required for washings. For consumers and corporate buyers, it would mean substantial savings. For the society, minimal cleaning/care represents reduction of energy costs, a better environment and reduced water pollution. It is well known that repeated washings accelerate the ageing or deterioration of garments and fabrics. The conventional wash and dry process is the cause for different mechanical, physical and chemical damages to fabrics and clothings. Dry cleaning is much less harsh; however, it requires polluting and volatile chemicals such as perchloroethylene and is an important source of harmful volatile organic compounds (VOC). Damage induced by repeated washings may include loss in tensile strength, tear resistance, dimensional stability and color change to name a few. Different strategies will be pursued to attain the self cleaning property: we will develop new functional chemistries based on photocatalytic-oxydation for the textile finishing formulations and also we will engineer original textile fabric surface designs to mimic the lotus effect.
