## Why Researchers Choose the AT235

Whether you're developing high-performance fibers, exploring novel polymer composites, or pioneering breakthroughs in smart textiles, the AT235 delivers a complete, end-to-end wet spinning simulation in a compact footprint — without compromising on precision or versatility.

---

## Engineered for Excellence, Designed for the Lab

The AT235 is built around a meticulously integrated spinning line, incorporating every critical stage of the wet spinning process:

Spinning Solution Tank → Dosing Pump → Gooseneck → Spinneret → Coagulating Bath → Drawing Rollers → Heating Slot → Setting Slot → Winding

This comprehensive process chain ensures that researchers can faithfully replicate production-scale spinning conditions at lab scale, accelerating the path from concept to validated prototype.

## Standout Features That Set the AT235 Apart

### Premium-Grade Material Construction

The gooseneck, coagulating bath, and spinning solution tank are all fabricated from 316L stainless steel — the gold standard for corrosion resistance and chemical compatibility, ensuring durability across a wide range of solvents and coagulation systems.

### ⚙ Flexible & Intuitive Operation

- A manual lifting platform allows the spinning solution tank, dosing pump, gooseneck, and spinneret to be raised or lowered together as a unit — enabling fast, precise adjustment of immersion depth without disassembly.

- The entire production line connects via quick-release joints, making setup, reconfiguration, and cleaning remarkably fast and hassle-free.

### Advanced Non-Contact Heating Technology

Both the heating slot and the setting slot utilize non-contact air heating, delivering uniform thermal treatment up to 250°C with precise PT100 sensor control. This gentle, contamination-free heating method is ideal for sensitive polymer systems.

### Independently Adjustable Drawing System

Three sets of nylon drawing rollers with independently adjustable speeds (3-40 m/min) give researchers full control over draw ratios at each stage, enabling systematic study of fiber morphology, orientation, and mechanical properties.

### Versatile Coagulating Bath

The generously sized coagulating bath (1000 × 160 × 160 mm) features two filament pressing rollers and an optional integrated heating system — accommodating a broad spectrum of coagulation chemistry and temperature conditions.

### Tantalum Spinneret for Demanding Applications

The included spinneret — 100 holes at 0.07 mm diameter, fabricated in tantalum — offers outstanding resistance to highly corrosive coagulation baths, making the AT235 ideal for fiber systems such as Lyocell, polyacrylonitrile (PAN), and other specialty polymers.
