Engineered specifically for high-speed Spunbond (SB) and Meltblown (MB) non-woven extrusion. Premium micro-dispersion with low Pressure Filter Value (DF < 0.5 bar·cm²/g).
Understanding the rheological requirements, thermal endurance, and filterability of Polyethylene colorants in modern high-speed spunbond and meltblown lines.
Non-woven fabric spinning demands exceptionally tight control over the Melt Flow Index (MFI). Standard injection grade masterbatches fail in non-woven lines due to melt fracture and uneven fiber drafting. Jiazhou's non-woven grade PE masterbatch is formulated using narrow molecular weight distribution (MWD) carrier resins with MFI ranging from 15 g/10min up to 45 g/10min (2160g / 190°C), ensuring frictionless spinning and uniform filament denier.
Filter blockage during continuous spunbond manufacturing results in costly machine downtime. Our production protocol enforces strict Filter Pressure Value (FPV / DF testing) under EN 13900-5. By guaranteeing pigment particle size reduction below 1.0 micron through triple-pass co-rotating twin-screw extrusion, our PE color masterbatches maintain a DF value under 0.5 bar·cm²/g, preserving spinneret mesh integrity.
Extrusion temperatures for PE and PP non-wovens typically range between 200°C and 260°C. Lower-grade organic pigments degrade under prolonged thermal exposure, causing yellowing, gas marks, and tensile strength loss. Jiazhou utilizes thermally stabilized organic phthalocyanines, quinacridones, and high-purity inorganic pigments capable of enduring continuous 260°C processing without chemical breakdown.

Key technological shifts driving global procurement in hygiene, medical protective wear, geotextiles, and eco-friendly packaging.
With global non-woven manufacturers pushing thread densities below 1.5 denier for softer hygiene applications and high-efficiency filtration (N95/FFP3 standards), traditional color masterbatches cause frequent spinning breaks and capillary plugging. The industry is rapidly shifting toward sub-micron pigment concentrates. As a leading China PE masterbatch supplier, Changzhou Jiazhou utilizes continuous ultrasonic dispersion combined with reactive wax additives, allowing seamless extrusion through micro-orifice spinnerets down to 0.15mm diameter.
Global buyers no longer look for color alone. High-value non-woven products require multi-functional compounding. Jiazhou's R&D hub has developed combined masterbatches that integrate Anti-UV protection (HALS technology), Permanent Anti-Static agents, Hydrophilic modifications, and Flame Retardant additives directly into the PE carrier matrix. This eliminates multi-dosing inconsistencies at the converter's hopper.
Driven by strict EU single-use plastic directives and global decarbonization mandates, non-woven converters require non-toxic, recyclable, and bio-compatible colorant systems. Jiazhou's PE color masterbatches utilize 100% heavy-metal-free organic pigments, zero volatile organic compounds (VOCs), and fully compliant bio-based low-density polyethylene (LDPE) or linear low-density polyethylene (LLDPE) carriers compliant with EN 13432 and ISO 14001 standards.
In medical drapes, surgical gowns, and baby diaper back-sheets, pigment migration or chemical bleeding when exposed to synthetic blood, alcohol, or body fluids poses severe biological hazards. Jiazhou's specialized non-woven masterbatch series undergoes strict cytotoxicity testing (ISO 10993) and zero-migration verification, guaranteeing color fastness under ethylene oxide (EtO) and gamma-ray sterilization processes.
Changzhou Jiazhou Plastic Products Co., Ltd. combines smart manufacturing automation with robust raw material integration to ensure uninterrupted global supply.
Our Changzhou plant operates multi-stage co-rotating twin-screw extruders equipped with loss-in-weight gravimetric feeders. This ensures high pigment loading (up to 50% concentration for white titanium dioxide masterbatch and 40% for organic color masterbatch) without pigment agglomeration or thermal degradation.
Every masterbatch batch undergoes rigorous testing prior to packaging: Datacolor Spectrophotometer color matching, melt flow index testing, moisture analysis, and spunbond simulation extrusion to measure pressure filter values (FPV). Complete batch traceability is preserved for 36 months.
Addressing key procurement challenges faced by international non-woven fabric manufacturers and OEM polymer converters.
Procurement directors face constant margin pressure. Jiazhou's high-concentration formulations offer low Let-Down Ratios (LDR between 1.0% and 3.0%), enabling non-woven manufacturers to achieve high color opacity and vivid hues while consuming less masterbatch per metric ton of virgin polymer resin.
Exporting finished non-woven goods to North America and Europe requires strict chemical transparency. All Jiazhou non-woven PE color masterbatches comply with FDA 21 CFR, EU Regulation 10/2011, REACH SVHC, RoHS 3.0, and OEKO-TEX Standard 100 Class I for baby skin contact.
Located in Changzhou, Jiangsu, Jiazhou benefits from proximity to major Eastern China deep-water ports (Shanghai and Ningbo). We maintain strategic inventory buffer stock for standard primary colors (White, Black, Blue, Green, Red, Yellow), reducing production lead times to 7–10 days globally.

Expert technical advice on selecting, dosing, and processing PE masterbatch for non-woven fabric manufacturing.
Yes. Polyethylene and Polypropylene are both polyolefins and exhibit excellent thermodynamic compatibility when melt-blended. A low-density PE (LDPE/LLDPE) carrier with high MFI (20–40 g/10min) acts as a internal lubricant in PP spunbond extrusion, reducing extruder backpressure while providing smooth fiber drawing without sacrificing non-woven fabric tensile strength.
We prevent spinneret blockage by enforcing strict Pressure Filter Value testing (EN 13900-5) on every production batch using a 200-mesh fine screen pack. Our nano-dispersive compounding technology keeps average pigment agglomerate size below 1 micron, maintaining a low DF value (< 0.5 bar·cm²/g) for continuous 72+ hour spinning cycles.
The typical dosage ranges from 1.0% to 3.0% depending on the required color opacity, fabric basis weight (GSM), and pigment concentration. For light medical blue or pink shades on 15–25 GSM spunbond fabrics, an LDR of 1.0%–1.5% is sufficient. For opaque agricultural black or high-density geotextiles, 2.5%–3.0% is recommended.
Absolutely. Our non-woven masterbatch series utilizes non-toxic, heavy-metal-free pigments compliant with FDA 21 CFR 177.1520, EU Regulation 10/2011, REACH SVHC, RoHS 3.0 directives, and OEKO-TEX Standard 100. They are safe for intimate skin contact in hygiene products and medical gowns.
Our in-house optical laboratory, equipped with X-Rite Datacolor spectrophotometers, delivers precise custom shade matching within 3 to 5 working days. Free masterbatch sample pellets (1kg–5kg) are available for immediate customer spinning trials.
When stored in its original unopened moisture-proof aluminum foil/PE bag in a cool, dry, ventilated warehouse away from direct sunlight, Jiazhou masterbatch retains optimal processing performance for up to 24 months without moisture pickup or color degradation.
