A MODIFIED LOW VISCOSITY STARCH
Ultra Size-LV is a premium grade product for warp sizing of cotton and Polyester-cotton blended yarn, to be woven on high speed shuttle less looms.
Ultra Size – LV:
Ultra Size – LV has a very low viscosity, which helps in better penetration, especially for higher thread counts / finer varieties. Normally a 15% paste has a viscosity of 8 to 9 seconds in 50 ml Texsize / ATIRA cup at 90°C. This low viscosity is very much suitable for all types of yarns, including dyed yarns.
Ultra Size-LV has an excellent adhesion property. The high tackiness in Ultra Size – LV helps in better binding and improvement in weaving efficiency in high speed shuttle less looms. A substantial reduction of other synthetic binders like PVA, Acrylic etc., is possible and this contributes in reduction of sizing materials cost.
Ultra Size-LV is highly consistent, which in turn helps in uniform size pick-up. A 15% paste remains consistent during overnight storage and there is no gel formation or thinning of paste.
Ultra Size-LV has an excellent film forming property. The film formed by Ultra Size-LV is strong, thin, transparent and does not crack easily. This in turn helps in better pliability and reduction of loss in elongation.
With continuous and preferably vigorous stirring, the required quantity of Ultra Size-LV is sprinkled to cold water in the cooker / pre-mixer, along with other additives. The suspension is cooked at 30PSI/130°C and retained for 10mts, before transferring to the storage tank.
