Effective Sizing Fundamentals
Today sizing is greatly concerned with good weaving with an optimum level of loom efficiency. The sizing mix is generally considered with two main ingredients. 1. Adhesives & 2. Lubricants. The function of the sizing is to improve the weaveability of the warp, i.e. to provide the yarn with the necessary properties to enable it to withstand the various stresses to which it is subjected in the loom. Regularity of the size mix. deposits are a primary consideration through uniform application by maintaining viscosity, adhesive power & plasticity during the entire run cycle. This outcome is highly dependent on,
- The nature of the size & the concentration of the size.
- The method of preparation or cooking (stirring, temperature & duration).
- Presence of additives.
The sizes used are generally macromolecular products in an aqueous system & their behavior is pseudoplastic. With starch rheological characteristics vary greatly with the method of cooking. There is a definite influence of concentration on viscosity. There is a great deal of debate over % of size add-on with respect to the strength and efficiency of loom operation. The following table is a useful guide.
