Nowadays, the end users of machine-made carpets have give the primary importance to some indicators before purchasing such as the carpet's life time, durability and appearance, comfort, and especially the human protection (in terms of dermal allergies and lung problems due to the carpet fly). For satisfying the consumer's requirements, on the other hand, the manufacturers are continuously looking for new ideas about the quality and desired physical and mechanical properties of the carpet in terms of their appearance and durability. Acrylic machine-made carpets have allocated the highest portion of consumption in the flooring textile group while the accumulated waste of this product is associated with environmental problems. For this reason, numerous researchers have studied different parameters of the carpet such as the paleness, hairiness, erosion, appearances maintenance and durability. The major problems of the acrylic machine-made carpet are their wear and hairiness which are related to low abrasion resistance of the yarns as well as the presence of hairy fibers on the yarn surface. To overcome this problem partially, it is necessary to change the yarn structure and the spinning type. For hairiness reduction and increasing the production efficiency of the ring spinning system, numerous modifications have taken into account. One of these modification performed is installing the grooved roller (solo) on top of the Ring delivery roller. In this system, the solo spinning triangle is divided into several sub-triangles. By applying twists, the hairy fibers would be placed between the spinning triangles; due to the fibers participated into the yarn structure, the number of protruded fibers from the yarn surface would be reduced. This in turn results in increasing the yarn abrasion resistance as well as uniform fibers distribution and compactness within the yarn cross-section compared to the conventional ring yarns. In the present study, the acrylic solo yarns as the carpet's pile yarns were produced using solo spinning system technology. The produced yarns were compared with the conventional ring yarns in term of their physical properties. The carpet samples of 1.5×1m 2 were then produced from both solo and conventional ring yarns were at 1500 and 2000 densities. Physical and mechanical properties of the carpet samples were evaluated. The statistical analysis results showed that the solo yarn hairiness has been decreased by 24 and 41% for 3 and 6 mm hair respectively, while the yarn abrasion resistance has been increased by 39%. Fiber distribution in the solo yarn cross section is uniform and much denser than the conventional ring yarns. There were no significant differences between the other physical properties of the yarns. The amount of the carpets thickness reduction under a dynamic load is lower for the solo yarn than the conventional ring yarn. Compressibility, permanent deformation, energy of compactness and residual energy of the carpet sample comprised of the solo yarn is less than the conventional ring spinning carpet. Elasticity of the carpet produced from solo yarn is more than samples containing the conventional ring yarn. Keywords: machine-made carpet, solo yarns, physical properties, abrasion resistance.
