Protection where
the yarn needs it.
Evaluate the selected PVA grade against your yarn, loom and finishing conditions.
Abrasion resistance
Support yarn resistance to the rubbing and tension of the weaving process.
Smoother yarn
Bind loose fibers to support handling and reduce shedding in a suitable size system.
Mill-specific preparation
Match solids, viscosity, pickup and desizing conditions to the selected grade.
Select with the process in view
Read the specification.
Look beyond the code.
PVA grades differ in hydrolysis, molecular weight and solution viscosity. Ask for the actual technical data and batch documentation before ordering or changing a recipe.

Textile PVA questions
Choose the grade
with your mill in mind.
What is PVA used for in textiles?
PVA, also called PVOH, is a film-forming polymer used in warp sizing to help protect yarn, bind loose fibers and support abrasion resistance during weaving.
What grade and pack are supplied?
The product packaging shows PVA 20–90 PG in a 25 kg pack. Confirm the exact ordered grade, current availability and batch specification with AlHaram.
Does the code prove a particular viscosity or hydrolysis?
Grade codes vary by producer. Request the manufacturer’s technical data sheet and batch certificate of analysis. Do not infer exact viscosity or hydrolysis from the packaging code alone.
Can PVA be used with starch?
PVA can be evaluated in suitable starch-containing size systems. Confirm grade compatibility, blend ratio, solids, preparation and desizing requirements in a controlled mill trial.
