Применение
Short-cut PVA fibers are matched to furnish, dispersion and target paper properties — strengthening sheets or forming sacrificial pores that dissolve after processing.
Paper and specialty nonwoven sheets need additive fibers that disperse evenly in water-based furnish. Poor dispersion creates flocculation and sheet defects, and the fiber must either bond permanently or leave the sheet at a defined stage.
PVA staple fiber is dosed into the furnish with the pulp blend. Length, fineness and surface condition control opening, distribution and bonding; water-soluble grades can later dissolve to create porosity or release a structured sheet.
Some grades must remain and reinforce the sheet; others exist to be removed — leaving pores or releasing a layer during processing. The required water behavior, not the product name, decides which grade fits.
Evaluate opening, distribution and compatibility under production-representative mixing, then measure the paper property that matters — strength, porosity or release — and record the approved dosage and process conditions.
