Abstract: | The advent of very high speed shuttleless looms has increased the importance of sizing. Starch has been the most popular and economic size material. Synthetic binders are also being blended with starch to improve weaving loom efficiency. Blending may lead to give different properties, which can be suited for particular application. In the present study effect of blend composition in modified starch and synthetic size blends have been evaluated and mechanical properties like cohesion power, adhesion power, abrasion resistance, bending rigidity etc were studied. In general, it is being observed that paste characteristics and film properties of polyester resin blends are better but because of economic reasons PVA and acrylic polymers are preferred. In this study the effect of lubricant is also observed. It is analyzed that lubricant improves the various mechanical properties and hence the weaving performance of the material. |
