The problem of textiles’ soiling is not a new one. Natural and synthetic textiles all get soiled during use by various mechanisms, including mechanical adhesion, adhesion by electrical forces or redeposition of soil during washing. However, the most important factor…
The textile finishing industry gives fabrics and garments their final appearance and properties. It employs traditional processes that are not environmentally friendly. These industrial activities have some environmental consequences, mainly related to the massive consumption of chemicals and intensive use of water and energy resources, waste-water treatments required, etc. Processes like desizing, bleaching, washing (roll-to-roll systems on fabrics) and dip-coating functionalization or dyeing (batch systems on garments) are currently developed by wet application systems and chemicals that require huge amounts of water and treatment of the waste-water released. The use of alternative chemistry like ozone for fabric treatment in a continuous way, and use of nanobubble technology for garment finishing is able to reduce the chemical consumption – also water consumption – in comparison with traditional systems.
The use of chemicals is one of the key factors in the sustainability and has a particular relevance in the textile and clothing sector, due not only to the legislation related with chemicals used (specially REACH, CLP and BPR Regulations) but also to clients RSL (restricted substance list) and campaigns from non-governmental organizations, such as the Detox campaign and ZDHC programme.
An interesting alternative to water-based recipes preparing yarns for weaving is coating with hotmelts, especially from an energy point of view. Traditional coating of warp yarn is done mostly on water based recipes: single yarns are coated conventionally within a…
Modifying the way textiles interact with water is a fundamental product differentiator. This report discusses super-hydrophobic surfaces used to create self-cleaning materials, faster-drying textiles, and improved stain resistance. Water Resistance This report concerns hydrophobicity in the context of textiles manufacture….
