Sizotex SPR



Sizotex – SPR is a highly modified and formulated Imported Starch product, free from PVA and any synthetic polymers. The high adhesive strength and the flexible film forming property of Sizotex – SPR provides the necessary elastic warp thread protection, which in turn contribute optimal flow characteristics during weaving. Sizotex – SPR produces excellent results in sizing of all type of yarns like cotton, synthetic and blends. Sizotex – SPR sizing baths have high stability of viscosity and do not form a skin.

Sizotex-SPR is easily desizable without enzyme. Sizing can be removed completely by washing in hot water (2 gpl of soda ash or soda lye is recommended).



Sizotex – SPR has a low viscosity, which helps in better penetration.  A 10% paste has a viscosity of 5 to 7 seconds in 50 ml TEXSIZE / ATIRA cup at 90 °C.  This low viscosity is very much suitable for all types of yarns, especially dyed yarns.


Sizotex – SPR has an excellent adhesive strength.  It also has very good tackiness, which in turn helps in better binding and improved weaving efficiency. It replaces all synthetic binders like PVA, Acrylic and other polymers also.


Sizotex – SPR is highly consistent and thereby ensures uniform pick-up.  There is no skin formation in size bath. There is also no retrogradation during overnight storage.

Low add-on

Dense constructions are easily woven at low size add-on, as there is more air space in the reed. Lower add-on results in less shedding on the loom.


Sizotex – SPR possess excellent water solubility and is easily desizable. Sizing can be removed completely by washing in hot water (2 gpl of soda ash or caustic soda lye is recommended). “No enzyme is required for size removal”.

Film Foramtion

Sizotex – SPR forms a strong and flexible film which in turn provides the necessary elastic warp thread protection. This will ensure better pliability and reduction of loss in elongation. Sizotex – SPR film has tough tensile strength and good elasticity, which provides excellent resistance to wear, with better smoothness and fluff binding properties.

Preparation of Sizing paste

Cooking is simple with Sizotex – SPR. With continuous and preferably vigorous stirring, the required quantity of Sizotex – SPR is sprinkled to hot water and stirred for 30 mts. Then the suspension is cooked at 130°C/30 psi and retained for 10 mts, before transferring to the storage. Sizotex SPR is also ideally suitable for atmospheric cooking.
