PVA Water Soluble Fiber - High Bonding Strength for Mortar Crack Resistance
5D*6MM PVA Water Soluble Fiber
Specifications can be customized
Product Overview
The 5D*6MM PVA water soluble short cut fiber addresses common challenges in wet processing industries. Traditional liquid PVA binders are difficult to disperse evenly and can cause local over-concentration, while ordinary reinforcing fibers like polypropylene do not dissolve and leave hard residues that affect surface finish.
This fiber-form PVA product provides the ideal solution. The solid fiber state enables easy feeding and accurate dosing, while the 6mm precision short length ensures rapid, uniform dispersion in water-based systems without clumping. As it dissolves, it releases PVA molecules evenly throughout the system, forming a continuous, uniform adhesive network that delivers consistent bonding and reinforcing effects.
The 5D denier balances dissolution rate and handling performance: fine enough for fast dissolution, yet thick enough for easy processing and dust-free operation. It can be added directly to pulp, mortar or paste in fiber form, eliminating the need for pre-dissolution and simplifying production processes.
As a 100% biodegradable and non-toxic material, it meets safety requirements for food contact and medical applications, helping manufacturers produce eco-friendly products that comply with global environmental regulations.
Application Scenarios
Wet Laid & Specialty Papermaking: Functional additive for household paper, food packaging paper, medical paper, filter paper and specialty paper. Improves both wet and dry tensile strength, reduces linting and dusting, and enhances surface smoothness.
Construction Mortar & Cement Products: Crack-resistant reinforcing fiber for cement mortar, putty powder, thermal insulation mortar and concrete. Dissolves during mixing to form a polymer network, improving mortar toughness, adhesion and crack resistance.
Wet Laid Nonwoven & Medical Materials: Binder and reinforcement for wet laid nonwovens, facial mask substrates, medical dressings and wound care materials. Dissolves uniformly to form a soft, flexible bonding layer with no hard fiber residue.
Textile Sizing & Printing: Warp sizing agent and printing paste thickener for cotton, linen and blended fabrics. Improves yarn strength and abrasion resistance for smooth weaving, and can be easily washed off after processing.

Core Features & Benefits
Cold Water Complete Dissolution, Zero Residue
100% pure PVA material dissolves rapidly and fully in cold/room temperature water without heating requirement. No insoluble fiber residue remains after dissolution.
Strictly controlled 5D denier and precision 6mm short cut with narrow length tolerance. Disperses evenly and quickly without clumping or tangling.
Strong Bonding & Reinforcing Dual Function
Forms a continuous PVA adhesive film with strong cohesive force. Works as both a binder and reinforcing phase to enhance tensile strength and crack resistance.
Fully Biodegradable & Eco-Friendly, Non-Toxic
Made from food-grade polyvinyl alcohol, fully biodegradable, non-toxic, odorless and free of harmful leachables. Meets food packaging and medical safety standards.
Wide Process & Application Compatibility
Compatible with wet laid papermaking, mortar mixing, wet laid nonwoven, textile sizing and printing paste processes. No equipment modification required.
Stable Quality & Batch Consistency
Virgin PVA raw material with strict in-line control over denier, length and dissolution rate. Consistent performance batch after batch minimizes production fluctuations.

What temperature does this PVA fiber dissolve in? Does it need hot water?
It dissolves rapidly and completely in cold/room temperature water (≥20℃) without heating. No hot water or high temperature condition is required, saving energy and simplifying production processes.
What is the difference between this PVA fiber and PVA powder / liquid?
Compared with PVA powder/liquid, this fiber form is easier to feed and meter, disperses more evenly in water-based systems without agglomeration, and causes no dust or blocking issues in automated production.
Does it leave any residue after dissolving? Can it be used for food contact paper?
It dissolves 100% completely with no insoluble fiber residue. Made from food-grade virgin PVA, it is non-toxic and safe for food packaging paper and medical material applications.
What does it do in construction mortar?
When added to cement mortar or putty, it dissolves during mixing and forms a polymer network structure. It significantly improves mortar toughness, adhesion and crack resistance.
Can it be blended with other fibers in papermaking?
Yes. It has excellent compatibility with wood pulp, polyester fiber, viscose and other common papermaking fibers. It can be added directly to the pulp in different proportions.
Can we get samples for dissolution and performance testing?
Yes, samples are available for dissolution test, strength test and production trial. Please contact us to request sample details.
What is the lead time for bulk orders?
Depends on order quantity and specification requirements. Standard specifications generally ship within 7-15 working days after deposit confirmation.
