A research on yarn and fabric characteristics of acrylic/wool/Angora blends

Acrylic fibers are one of the most commonly used synthetic fibers and due to its low thermal conductivity, good shape retention and durability properties, they have a large application area in knitted garment industry. Acrylic fibers are also used in blends to benefit from more prominent features of other fibers. Wool with having good wrinkle resistance, moisture absorption and warmth is a good blend material for acrylic. In order to get superior tactile properties, luxury animal fibers can also be used in acrylic blends, despite there are spinning difficulties and production limitations for these fibers. In this study, acrylic fiber and its blends with wool and Angora rabbit fiber were investigated for their yarn and fabric properties. According to the experimental results and the statistical analyses, it was concluded that, blending acrylic fiber with wool and Angora rabbit fiber, increases the CVm, thin/thick places and neps of the yarn. Yarns containing 100% acrylic and 70% acrylic/10% wool/20% Angora have the highest tensile strength. In case of yarn friction coefficients, 70% acrylic /20% wool /10% Angora containing yarn has the highest coefficient of yarn to pin and yarn to yarn friction values. However, 70% acrylic/30% Angora and 100% acrylic yarns have lower values, supplying smoother yarn surface. 100% acrylic yarn and 70% acrylic/10% wool/20% Angora yarn have the highest breaking strength values, similarly, the fabrics of these yarns have the highest bursting strength values. 70%acrylic/10% wool/20% Angora fabric and 70% acrylic/30% Angora fabric have the lowest circular bending rigidity, which mean that they have the softest handle
