What are the characteristics of multifunctional spinning and texturing testing machine?

Multifunctional spinning and texturing testing machine is a special equipment that integrates the core functions of "spinning" and "texturing" and adapts to the needs of multi-scene tests. Its characteristics are developed around five cores: functional integration, process flexibility, parameter accuracy, intelligent operation and diversified application, as follows:

First, the function is highly integrated: "spinning-texturing" is integrated to simplify the test link.

The traditional experiment needs to be completed in two steps: spinning the precursor with spinning equipment and processing the elastic yarn with texturing equipment. The equipment integrates the spinning system (raw material melting, spinning, cooling and drafting) with the texturing system (false twist deformation, heat setting, secondary drafting and winding) to realize the continuous experiment of the whole process from polymer raw materials (such as chips and melts) to finished elastic yarn, without the need.

Typical integrated modules: raw material feeding unit, melt spinning box, cooling tunnel, drafting roller, false twister (such as friction disc false twist, air false twist), heat setting roller (or hot box) and winding device, all of which cooperate with each other to reduce the loss of test links and improve efficiency.

Second, the process is flexible and adjustable: to meet the needs of multi-variety and multi-parameter tests.

The core advantage of the equipment lies in its "versatility", which can cover the tests of different materials and specifications of elastic yarns through parameter adjustment to meet the requirements of research and development or small batch verification:

Wide material compatibility

Support a variety of polymer raw material tests, including synthetic fibers (PET, PA6, PA66, PP), functional fibers (such as flame retardant and antibacterial modified chips), recycled fibers (recycled PET chips), etc., and switch raw materials without replacing a large number of core components.

Large adjustable range of process parameters

Key parameters can be accurately adjusted to meet different product requirements:

Spinning end: melting temperature (200-350℃, suitable for different polymer melting points), spinneret specifications (different hole numbers/apertures can be changed to make monofilaments, multifilaments or superfine denier filaments), and cooling wind speed (0.5-3m/s, and the cooling rate of filaments is controlled);

Elastic end: false twisting speed (5000-30000r/min, adjusting deformation effect), heat setting temperature (80-220℃, controlling thermal stability of elastic yarn), and drafting multiple (1.2-5 times, adjusting yarn strength and elongation).

Function mode can be switched.

Support "pure spinning mode" (only making precursor), "pure texturing mode" (texturing externally input precursor) and "spinning-texturing linkage mode" (making elastic yarn in the whole process), and flexibly match different test scenarios.

Third, accurate parameter control: ensuring the reliability of test data

As a test equipment, data accuracy is the core requirement, and the equipment realizes accurate control of parameters through multiple technologies:

High precision measurement and control system

Temperature control: PID closed-loop control is adopted, and the temperature error of spinning box and heat setting roller is ≤ 1℃, so as to avoid temperature fluctuation affecting the melting/setting quality of filaments;

Rotational speed: the rotational speed control accuracy of drafting roller and false twister shall be ≥0.1%, so as to ensure the stability of drafting multiple and false twist, and reduce the yarn evenness deviation;

Tension: equipped with high-precision tension sensor (range 0-500cN, accuracy 0.5%) to monitor the tension of wire in real time and give an alarm automatically when it is abnormal, so as to avoid defective products caused by broken wire or uneven tension.

Stable molding guarantee

The winding device adopts "constant tension winding" technology, and the winding shape is neat (the end surface roughness is less than or equal to 1 mm), and there are no loose loops and overlapping wires, which is convenient for subsequent sample testing (such as breaking strength and elastic recovery rate testing).

Fourth, intelligent operation: lower the operating threshold and improve the test efficiency.

Convenient human-computer interaction

Equipped with touch screen or industrial computer, it supports visual setting of parameters (such as temperature, rotation speed and draft multiple) and process recipe storage (100+sets of recipes can be stored and directly called in the next similar test), without manual mechanical adjustment, thus reducing operation error.

Automation and security protection

Automation function: automatically stop when raw materials are short of materials, automatically cut off the heating power supply and give an alarm when broken wires, and prompt in real time when the equipment operation parameters exceed the limit, thus reducing the intensity of manual duty;

Safety design: the equipment shell is grounded (grounding resistance ≤4Ω), and high-temperature components (such as spinning box and hot roller) are provided with protective fences and emergency stop buttons (all operating positions of the equipment are arranged) to ensure the safety of operators.

V. Diversified application scenarios: covering R&D, testing, teaching and other fields.

This equipment is not only suitable for fiber research and development of enterprises/scientific research institutions, but also can meet the requirements of multiple scenarios:

R&D end: developing new elastic yarns (such as low elastic yarns, high elastic yarns and different shrinkage yarns), optimizing process parameters (such as testing the change of elastic recovery rate by adjusting the false twist speed), and verifying modified raw materials (such as the elastic effect of PET chip spinning with antibacterial agent);

Detection end: re-examine the quality of the finished elastic yarn (such as simulating the production process to test the heat resistance and elastic stability of the yarn), or evaluate the "spinning elasticity applicability" of the chips provided by raw material suppliers;

Teaching end: As the teaching equipment of textile specialty in colleges and universities, it directly shows the whole process of "spinning-texturing" to help students understand the principle of fiber forming and cultivate their practical ability.

Six, compact structure and easy maintenance: adapt to the laboratory scene

Compared with the industrial production line (which occupies a large area and needs multi-equipment linkage), the multifunctional spinning and texturing testing machine has a compact body design (usually occupies an area of ≤ 5m2) and is suitable for the limited space of the laboratory; At the same time, the core components of the equipment (such as spinneret, false twister and filter core) are modularized, which is convenient to disassemble/replace (for example, the replacement time of spinneret is ≤30 minutes), and the daily maintenance (such as cleaning roller and lubricating transmission parts) is simple, thus reducing the later maintenance cost.

To sum up, the multifunctional spinning and texturing testing machine, with the characteristics of "integration, flexibility, accuracy and intelligence", can not only meet the diversified needs of fiber research and development, but also ensure the reliability of test data, and is one of the core equipment for R&D innovation and quality inspection in textile industry.
