| Abstract | ||||
| The use of sirospun yarns eliminates two processing stages in comparison with the two-fold yarns production process and consequently, reduces the cost of production. It is claimed that, it brings many advantages for yarn and fabric quality. However, the benefit of this new concept is still to be investigated extensively. The aim of this paper is to present and analyse the quality parameters of the (sirospun yarns and conventional two-fold yarns and fabrics) of counts 50/2 and 80/2. In addition, the yarn properties of single yarn counts 25/1 and 40/1. Giza 88 Egyptian cotton combed at 18% noils was used. Yarn physical properties including tensile strength, elongation, unevenness and hairiness were measured and compared. The sirospun yarn values achieved were superb, with regard to yarn strength, elongation and hairiness. The results indicated that increasing the yarn count within the range of Ne 50/2 to Ne 80/2 decreased the hairiness of sirospun yarn. It is also shown that the hairiness of sirospun yarns is significantly less than that of two-fold ring spun yarns. According to results, the structural differences between sirospun and conventional two-fold yarns had a significant influence on weft direction fabric properties. Weft direction woven from sirospun yarns were found to have higher tensile strength than fabrics woven from ring two-fold yarns. The test results regarding color reflectance and color strength (K/S) indicated that there is insignificant difference in color reflectance between the fabrics of sirospun and conventional two-fold yarns in 80/2 and 50/2 Ne. The sirospun fabrics recorded slightly lower color strength than the conventional two-fold yarn fabrics. This result reveals that much less dye can be used for the fabrics of sirospun fabric, so their dyeing cost might be lower for the same depth of shade in comparison to fabrics of conventional two-fold yarns. | ||||
