Flame Retardant Staple Fiber for Papermaking 1.5D×6MM
Fireproof Filter Paper Base Fiber Used in battery separators and special paper manufacturing
Specifications: 1.5D×6MM (Customizable)
Product Overview
Our 1.5D×6MM inherent flame retardant ultra-short staple fiber is a professional synthetic pulp raw material specially developed for the wet-laid flame retardant papermaking industry. Unlike common polyester short fibers and surface-coated fireproof fibers, this product uses halogen-free intrinsic flame-retardant polymerization technology, integrating fire-resistant functional groups permanently into the fiber molecular structure.
The optimized 1.5D fine denier provides fine fiber texture that combines tightly with plant wood pulp without compromising original pulp paper toughness. The standard 6mm ultra-short fixed cut is ideal for global wet papermaking lines, solving core industry challenges including fiber winding, poor water dispersion, uneven paper formation, and unstable fire resistance in mixed pulp paper.
Key Features
Superior water wetting and dispersion performance
Rapid mixing in water pulp without floating or caking
Compatible with high-speed circulating pulping equipment
Uniform fiber distribution and flat paper surface
High tensile strength and excellent folding performance
Stable self-extinguishing performance with no secondary combustion
Low smoke and non-toxic combustion characteristics
Manufactured from virgin PET raw material in closed-loop dust-free production
Application Scenarios
Industrial Flame Retardant Base Paper: Fireproof insulating paper, electrical equipment fire barrier paper, industrial fire isolation wrapping paper
Architectural Fireproof Paper Material: Fire-resistant decorative backing paper, wall fireproof lining paper, building thermal insulation fireproof pulp board
Functional Filter Paper: High temperature resistant flame retardant filter paper, industrial dust removal fireproof filter pulp, air purification fireproof filter paper
Inherent Permanent Flame Retardant: Internal molecular grafting flame-retardant modification technology ensures permanent fire resistance that won't degrade after washing, pulping, or high-temperature drying.
Optimal Papermaking Size: Professional 1.5D fine denier and 6mm ultra-short length prevents fiber winding and ensures perfect compatibility with plant wood pulp.
Excellent Water Dispersion: Special hydrophilic spinning treatment enables rapid, uniform dispersion without floating fibers or bottom precipitation.
Self-extinguishing & Low Smoke: Meets international fire protection standards with automatic extinguishing, no flame spread, and no toxic gas release.
High Wood Pulp Compatibility: Perfect blending with various plant pulps enhances tensile strength, tear resistance, and folding endurance.
Low Dust & Low Fibrillation: Precision cutting process minimizes broken filaments and debris, reducing equipment cleaning and material loss.
Eco-friendly & Compliant: Halogen-free formula meets EU environmental standards, safe for indoor and industrial applications.
Frequently Asked Questions
Q1: Is the flame retardant function permanent?
A1: Yes, intrinsic molecular modified fireproof structure ensures permanent fire resistance that won't fail after pulping, washing, and drying processes.
Q2: Why choose 1.5D 6mm for papermaking?
A2: The fine denier and 6mm ultra-short size prevent fiber winding, provide superior water dispersion, and perfectly match wet papermaking pulp processes.
Q3: Will it produce toxic gas when burning?
A3: No, the halogen-free eco formula produces low smoke, is non-toxic, creates no molten drip, and poses no secondary fire hazard.
Q4: Can it blend with wood pulp and plant pulp?
A4: Excellent compatibility allows free mixing ratios to efficiently improve paper fireproofing and physical strength.
Q5: Is it easy to disperse in water pulp tank?
A5: Superior hydrophilic dispersion treatment ensures fast, uniform dissolving without agglomeration or floating fibers.
Q6: Does finished fireproof paper curl easily?
A6: Ultra-low shrinkage fiber maintains flat paper structure with no curling or deformation after drying.
Q7: Are free samples available for pulp trial?
A7: Yes, free test samples are provided for papermaking trials and fire performance testing.
