Impact of Different Sizing Agent on Mechanical Properties of Cotton Yarn

Physical-mechanical properties of three 100% single cotton yarns (counts of 20, 30 and 50 tex) sized with three different size types were analyzed. These different size types were obtained by changing the sizing agent in the unique recipe in the same conditions of sizing and drying. Very interesting results were achieved. The sizing processes were carried out on the laboratory sizing machine in the conditions adapted to the industrial ones. By analyzing the results it can be established that there is a certain difference among the yarn properties sized by different size types. The highest breaking forces, elongations at break, work to rupture and tenacities have yarns sized with Tuboflex PVA 80, and the lowest ones have yarns sized with Tuboflex S 30. But when it comes to hairiness, the situation is opposite. Tuboflex SGP 30 does not differ much from Tuboflex S 30 in all properties.
