Development of processes using modified proteases for the reduction of felting and shrinkage of wool textiles
Four commercial proteases were characterised in terms of their activities, protein concentrations, optimum application conditions (pH and temperature) and suitable buffer systems in order to obtain maximum performance on wool. Different wool pre-treatments using oxidising or reducing agents in …

Felted Objects via Robotic Additive Manufacturing
… of felt to make three dimensional objects. Felting is a method of intertwining fibers to make a piece of textile. In this work, a 6 DOF UR-5 robotic arm equipped with a 3 DOF tool head to test various approaches to using felting. Due to the novelty of this approach several different control …

Thermostabile und alkaliresistente Proteasen in der Wollveredlung : Möglichkeiten der industriellen Nutzung und Auswirkungen auf Wolle
… because of ecological and economic reasons. The felting tendency of the enzyme treated fabrics was significantly reduced but for strongly felting fabrics an anti-felting treatment can not be reached. The fabric that was used to compare the chlorination to the enzyme treatment showed only a slight …

Modifizierung von Wolle durch Enzyme mit dem Ziel der Griffverbesserung und Filzfreiausrüstung
… treatment compared to the reference sample. The felting of merino wool top is not reduced by the enzyme treatment described above. The felting of crossbred wool, however, was significantly reduced after enzyme treatment in comparison to the reference fibres and untreated crossbred wool. The …

La materia fibra de lana - no tejido - y su exploración hacia nuevas configuraciones para aplicaciones sustentables
… Wool producers. This fiber has the ability of felting and conform a not-knitted fabric from a really simple hand craft technology. This was the start point for the exploration of a new sustentable configuration, in the design process and within a specific context: Hand craft chain of value …

Enzymatic treatment of wool with modified proteases
… with the purpose of providing resistance to felting and shrinkage. There have been many attempts to replace this chlorine process by an environmental friendly enzymatic process that wouid similarly degrade the scales. However, although proteases are large molecuies, their attack is not oniy …

Zur Einwirkung von Ozon auf Wolle und Aminosäuren
… to untreated wool top, a decrease of the felting behaviour is assessed. Ozonation of wool fabrics also leads to a smoothing of the surface. The levelling is due to an extraction of proteinic materials which cover the surface of the single fibres and act as a kind of glue. The fabric …
