The effect of a new setting agent for wool

Pleated wool fabrics were prepared by the treatment with ethylenediamine (EDA) at 90°C for 30 min. The degree of set, tensile property and dyeing of the treated fabrics have been discussed in relation to the concentration of EDA in the treatment system. No significant decreases in tensile strength and elongation, and great increases of exhaustion of synthetic and natural dyes were observed. Pleat and flat set were successfully attained in a wide range of the concentration of EDA. Excellent dyeability and setability of the fabrics obtained were considered to be associated with the existence of new crosslink, β-N-(2-aminoethyl)alanino-β-aminoalanine and the pendant group, β-N-(2-aminoethyl) aminoalanine produced by the reaction of EDA with dehydroalanine intermediate. © 2009 The Korean Fiber Society and Springer-Verlag Berlin Heidelberg GmbH

Relationship between various chemical treatments on the mechanical, anti-felting and dyeing properties of wool

Wool fibers have higher elasticity than synthetic fibers, and are superior in the properties of vapor absorption and desorption. However, the only fault of wool is its felting propensity during home laundering. Although various anti-felting treatments to reduce the felting property have been developed and used industrially, there are still problems such as environmental issues and changes of fabric handle. These issues were studied in this paper. The effect of DCCA, NaOCl and plasma treatments on anti-felting property, fabric handle, yellowing, color intensity and hydrophilicity were especially investigated. It is concluded that NaOCl method is the best treatment in the points of anti-felting, fabric handle, yellowing and color intensity. © (2012) Trans Tech Publications
