Etere di cellulosa per Non-Woven Applications

HEC, CMC, and HPMC may each be used in selected non-woven coating, binder, and treatment formulations. HEC is the most commonly used grade for smooth viscosity control and broad binder compatibility. CMC is used for suspension support and formulation consistency. HPMC may be considered in specialty systems requiring water retention or controlled coating behavior.

HEC provides smooth, consistent viscosity control, rheology adjustment, coating body, and treatment bath stability in selected water-based non-woven systems. Its non-ionic character gives it broad compatibility with polymer dispersions, binders, surfactants, and functional additives commonly used in non-woven treatment formulations.

CMC helps support suspension of fillers, pigments, functional particles, and solid additives in selected non-woven treatment formulations. It also contributes to viscosity adjustment and formulation consistency, helping maintain uniform treatment appearance and reducing settling during production.

Yes. Cellulose ether can help control viscosity and rheology, which supports more uniform coating or treatment application across the non-woven substrate. Final coating uniformity depends on the substrate structure, application method, binder system, wet pickup level, and drying conditions.

Selected cellulose ether grades may be used in wipe or hygiene-related treatment systems. Final suitability depends on the specific product grade, formulation design, safety documentation, and market-specific regulatory requirements. Grade selection for hygiene and medical applications should include a full compliance review.

A common reference dosage range is approximately 0.05%–1.5% by formulation weight, depending on the formulation type, target viscosity, application method, binder system, and cellulose ether grade. Wipe and hygiene treatments typically use lower dosages, while specialty functional coatings and industrial finishes may require higher dosages. Final dosage must be confirmed through formulation testing.

Viscosity loss in non-woven treatment formulations may be caused by pH changes, electrolyte content, binder incompatibility, preservative interaction, temperature variation, shear during pumping, poor initial hydration, or an unsuitable cellulose ether grade for the specific formulation system. A full formulation review including pH, ionic content, and binder compatibility can help identify the cause.

Start by defining the fiber type, binder system, application method, target viscosity, wet pickup requirement, additive suspension needs, drying conditions, final product performance requirements, and storage stability target. LANDERCOLL can recommend suitable HEC, CMC, HPMC, or selected cellulose ether grades for your specific non-woven formulation system and arrange samples for testing.
