Product Overview

Fiber Titanium Dioxide Masterbatch is a special functional masterbatch developed specifically for the textile and chemical fiber industry. It is produced using high-purity fiber-grade titanium dioxide combined with high-quality PET carrier resin through intensive mixing, uniform dispersion and standardized pelletizing processes. With three core functions of whitening, hiding and delustering, it is the key additive for achieving semi-dull and full-dull finishing in chemical fiber products such as PET polyester staple fiber and POY/FDY/DTY filaments, and is fully suitable for both virgin chemical fiber and recycled bottle flake spinning.

Fiber Titanium Dioxide Masterbatch and excellent filtering performance, this product completely solves common industry problems of traditional titanium dioxide powder, including dust flying, agglomeration, screen clogging and uneven dispersion. It can be directly melt-spun with chemical fiber chips without modifying existing production processes. It not only provides chemical fiber products with pure high whiteness and strong hiding power, but also achieves a soft delustering effect through the unique optical properties of TiO₂, enhancing fiber texture and appearance grade. Meanwhile, it does not damage the mechanical properties of fibers, offers excellent spinnability, effectively extends spinning cycles, reduces equipment maintenance costs, and supports efficient and low-cost production.

Core Product Advantages

Dual Whitening & Delustering Effect: Enriched with high-purity fiber-grade TiO₂, it delivers pure whiteness and strong hiding power, quickly neutralizing yellow and gray tones of chemical fibers while achieving soft delustering. It perfectly meets the semi-dull and full-dull requirements of PET fibers, improving product texture and added value.

Excellent Dispersion & No Filter Clogging: Uniform particle size distribution with special dispersion treatment ensures no agglomeration, caking or dusting during processing. Outstanding filtering performance prevents clogging of spinning assemblies and filters, greatly extending spinning cycles and reducing downtime for maintenance.

Strong Spinnability & Wide Adaptability: Highly compatible with PET polyester substrates, suitable for various processes including polyester filament, staple fiber and recycled bottle flake spinning. It does not affect fiber tensile strength and ductility, with excellent post-dyeing performance and no color streaks or deviations.

High Concentration, High Efficiency & Low Cost: With 40%–60% high-concentration active ingredients, ideal whitening and delustering effects can be achieved with a small dosage, eliminating repeated additions, reducing raw material and labor costs, and improving overall production efficiency.

Weather Resistance & Stable Quality: Migration resistance ≥ Grade 5, light resistance ≥ Grade 7. Whiteness and delustering effect remain stable for a long time without precipitation, yellowing or fading. Consistent performance across batches ensures stable finished product quality.

Flexible Customization: TiO₂ concentration and carrier material can be customized according to fiber type, delustering level (semi-dull/full-dull) and whiteness requirements to meet various personalized production needs.

Technical Specifications

Application Fields & Processing Technologies

This product is specially designed for the chemical fiber spinning industry and widely applicable to various polyester fiber productions. Core application scenarios are as follows:

Core Chemical Fiber Field: PET polyester staple fiber, POY/FDY/DTY polyester filament, high-tenacity industrial yarn, recycled polyester fiber spinning, mainly for semi-dull, full-dull, whitening and hiding treatment of fibers.

Downstream Application Scenarios: Garment fabrics, home textiles, industrial textiles, decorative fabrics and other chemical fiber products, suitable for high-end chemical fiber products with requirements for whiteness and delustering texture.

Compatible Processes: Conventional chemical fiber production processes including polyester melt spinning, filament texturing, staple fiber processing, recycled bottle flake spinning and extrusion, directly used as whitening and delustering agent throughout production.

Usage

No fixed addition ratio; flexibly adjusted according to fiber type, required whiteness and delustering level (semi-dull/full-dull). A small-scale trial before use is recommended to determine the optimal dosage.

The above parameters are standard laboratory test data for production reference only. Actual performance may vary slightly due to differences in raw materials, formulations, processing equipment and technologies of downstream manufacturers. Sample trial production is recommended before mass production.
