Texsize-A
Texsize-A is a thin boiling starch suitable for sizing and finishing operations in the textile Industry for medium to fine range yarns.
Advantages
Description
Texsize-A is a partially hydrolysed starch product. Due to the reduction in the chain length, the pastes of Texsize-A is less viscous than those of unmodified starches. It is an ideal product for sizing of both grey and dyed cotton, polyester cotton yarn of medium to fine counts.
Applications
Texsize-A is ideally suited for use in warp sizing and finishing of cotton and polyester-cotton blends. Uniform paste properties of Texsize-A ensure substantially constant textile performance. The warp threads undergo friction and tension during the weaving process. The efficiency of weaving depends upon resistance to abrasion of warp yarn. Texsize-A provides protection to yarn to meet the friction and tension by giving uniform size penetration without developing abrasive points, even on over drying.
Preparation
Fill the cooker with the required quantity of water. Start agitation and add the required quantity of Texsize-A allows it to disperse uniformly. Raise the temperature to 130°C /30 psi and retain for 10 mts, before transferring to the storage tank.
Texsize-A is formulated to be used along with binders and lubricants for all counts of cotton and polyester cotton blends at dry pick-up levels of 6% to 20% to achieve maximum efficiency at loom shed.
