Self cleaning textile fabrics

提出了用于制造服装、外衣、室内装饰（包括家具）和休闲织物的自清洁纺织织物的开发，以朝着纺织织物需要最少洗涤、护理和修理的理想情况发展。赋予服装和织物的这些属性与生态设计有关，而自清洁概念最终导致寿命的显着延长，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，这将意味着节省大量资金。对社会而言，最低限度的清洁/护理意味着降低能源成本，改善环境和减少水污染。众所周知，反复洗涤会加速服装和织物的老化或劣化。传统的洗涤和干燥过程是造成织物和服装不同的机械、物理和化学损伤的原因。干洗是不那么苛刻;然而，它需要污染和挥发性化学品，如氯乙烯，是有害的挥发性有机化合物（VOC）的重要来源。重复洗涤引起的损坏可能包括拉伸强度、抗撕裂性、尺寸稳定性和颜色变化的损失，仅举几例。我们将采取不同的策略来实现自清洁特性：我们将开发基于光催化氧化的新功能化学品，用于纺织品整理配方，我们还将设计原创的纺织品织物表面设计，以模仿莲花效应。

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.
