Nonwoven Line Ancillary Equipment & Custom System Integration - Drying, Metering, Filtration Solutions
BOSTONE offers a complete range of Nonwoven Line Ancillary Equipment: including high-precision drying, BICO metering, efficient melt filtration, and air drawing systems. We ensure your PP, PET, PLA lines achieve maximum operational stability, product uniformity, and economic efficiency.
Core value proposition and system integration concept
In the field of high-performance nonwoven fabric manufacturing, the powerful performance of main equipment (such as extruders and spinning boxes) relies on precise and reliable supporting facilities to be fully realized. Bostone firmly believes that supporting systems are not simply additional equipment, but rather the lifeline for ensuring high product uniformity, high OEE (Overall Equipment Effectiveness) of the production line, and low operating costs.
Our value proposition lies in achieving end-to-end digital control of raw material quality, melt cleanliness, and additive proportions through the most sophisticated auxiliary systems. This means we can eliminate all potential fluctuations and defects from granule feeding to the point where the melt enters the spinneret.
Our system integration philosophy revolves around “building an extremely precise melt environment,” ensuring that whether you’re producing PP spunbond fabric, high-melting-point PET fiber, or moisture-sensitive PLA, you achieve the highest industry standards:
Risk Elimination: From the very first step, an ultra-efficient drying and crystallization system completely eliminates the hydrolysis risk of PET and PLA, ensuring the stability of polymer molecular weight—the fundamental guarantee of consistent fiber strength.
Precision Assurance: By employing loss-in-weight metering and high-precision gear pumps, we ensure the proportioning and flow control of masterbatch and BICO melt are precise to the micron level. This directly determines the color uniformity and fiber structure consistency of the final product.
Challenges and Countermeasures for PET Spunbond Line
| Technical Challenge | Detailed Problem Description | BOSTONE'S Refined Solution |
|---|---|---|
| Hydrolysis Sensitivity of PLA Melt | PLA is highly hygroscopic. Water molecules react with the polymer at high temperatures, leading to a rapid decrease in molecular weight and significantly reduced fiber strength. | Integrated Ultra-Efficient Pre-heating & Dehumidifying Drying System: Strictly controls the moisture content of PLA granules to below 50 ppm (far below the industry standard) at the front-end mixer and dehumidifying dryer, fundamentally eliminating water-induced hydrolysis risks. |
| High Melt Viscosity & Spinning Stability | PLA melt has high viscosity and poor fluidity, making it difficult to produce ultra-fine fibers and easily causing melt accumulation or blockage at the spinneret exit. | High-Precision Metering Pump & Low-Resistance Components: Utilizes a high-precision melt metering pump to ensure stable melt output; optimizes melt conveyance pipelines and distributor design to reduce flow resistance, ensuring stable and uniform melt flow through the spinneret. |
| Product Softness & Brittleness | PLA fibers are inherently harder and stiffer than PP, which may result in a finished product lacking the required softness and hand-feel, making it unsuitable for certain high-end hygiene applications. | Dedicated Spinning & Hot Rolling Process: Effectively lowers the crystallinity and improves the hand-feel and softness of the PLA non-woven fabric by adjusting the spinning temperature and cooling rate, and by using low-pressure, special-pattern hot rolling processes without causing thermal degradation. |

TCO Optimization and Waste Minimization
Precise raw material metering eliminates waste
A high-precision loss-in-weight dispensing system and high-precision metering pumps ensure that the ratio of polymers and expensive additives (such as UV stabilizers and color masterbatches) reaches an accuracy of 0.5% per liter. This not only guarantees consistent product functionality but also effectively avoids raw material waste caused by incorrect proportions or uneven metering.
Extended Effective Uptime
The combination of a high-efficiency melt filter and a calcining furnace/ultrasonic cleaner maximizes the spinneret cleaning cycle. Reduced downtime for cleaning means your production line can run for longer, directly improving overall equipment efficiency (OEE) and significantly reducing downtime losses.
Energy-efficient design
Our energy-consuming systems, such as thermal oil heaters, air heaters, and Roots blowers, all feature high-efficiency designs and intelligent temperature control. Precise thermal management minimizes energy waste, significantly reducing energy consumption per unit of product, especially when operating high-temperature production lines such as PET.
The value of stability and consistency
An ultra-efficient drying system and melt flow channel purification ensure highly consistent physical properties of the final fiber web. This zero-defect and batch-to-batch uniformity allows your nonwovens to easily pass stringent medical, food-grade, or geotextile standards.
High-end market access
Stable supporting facilities are a prerequisite for producing high-end functional products such as SSMMS and BICO. By achieving higher performance indicators (such as higher BFE and stronger tensile strength), your products can enter the high-end market and obtain profit margins several times higher than ordinary PP spunbond fabrics.
