Research on the thermal protection performance of composite nylon tasron fabric in fire garments
1. Introduction
With the continuous development of modern fire fighting technology, the dangerous environment faced by firefighters is becoming increasingly complex. Multiple threats such as high-temperature flames, radiant heat and chemical leakage have put higher requirements on fire garments materials. As a high-performance textile material, Nylon Taslan has gradually become one of the important choices in fire garment design due to its excellent wear resistance, tear resistance and lightweight properties. However, its performance in extreme thermal environments, especially in thermal protection performance, still needs to be studied in depth.
This study aims to explore the thermal protection performance of composite nylon tasron fabrics in fire garments, and to evaluate its potential and limitations in practical applications through experimental data and theoretical analysis. The article will discuss from multiple aspects such as material properties, thermal protection mechanism, experimental design and result analysis, and also cite famous foreign literature to support the research conclusions.
2. Basic characteristics of composite nylon tasselon fabric
1. Material Overview
Composite nylon tasron is a functional fabric made of nylon fibers through a special weaving process. The surface has a unique gloss after being calendered, with good wear resistance and waterproof performance. Compared with ordinary nylon fabrics, the Taslon has a tighter structure, so it has stronger tear resistance. In addition, by combining with other functional fibers, Tasilon fabrics can also achieve flame retardant, heat insulation and other functions.
| parameter name | Unit | value |
|---|---|---|
| Density | g/cm³ | 1.14 |
| Tension Strength | MPa | 60-80 |
| Abrasion resistance | times | >50,000 |
| Flame retardant grade | – | B1 (European Standard) |
2. Main advantages
- High strength and durability: Composite nylon taslin has extremely high tensile strength and wear resistance, and is suitable for use in scenarios with frequent friction or high stress.
- Lightweight Design: Compared with traditional defenseThe density of fire materials (such as aramid) is lower, and can effectively reduce the overall weight of the fire garment.
- Multifunctional Composite Capability: Taslon can meet a variety of special needs by adding flame retardants or other functional coatings.
3. Current status of domestic and foreign research
In recent years, the application of composite nylon taslon in the fire protection field has attracted widespread attention. According to a research report by the National Fire Protection Association (NFPA), Taslon materials can provide thermal protection that is better than traditional materials under certain conditions. For example, in an experiment conducted by the Royal Fire Academy, researchers found that specially treated Tasilon fabrics can withstand high temperatures up to 800°C in a short period of time without the occurrence of a new temperature in the future. Apparent melting or combustion.
3. Analysis of thermal protection performance
1. Thermal protection mechanism
The thermal protection performance of composite nylon tasron mainly depends on the following aspects:
- Low thermal conductivity: The gap between the Taslin fibers is large, which can form an effective thermal insulation layer to reduce the speed of heat transfer inward.
- Flame Retardant Coating Effect: By applying flame retardant to the surface of the fabric, the burning speed of the material can be delayed in a fire environment, thereby protecting the wearer.
- Multi-layer structural design: Modern fire garments usually use multi-layer composite structures, with Tasilon as the outer layer material responsible for resisting the influence of external heat sources, while the inner layer uses moisture-absorbing and sweating materials. To improve comfort.
2. Experimental Design
In order to verify the thermal protection performance of composite nylon tasron, the following experimental scheme was designed in this study:
- Experimental Equipment: Use the TPP tester (Thermal Protective Performance Tester) from Schmidt & Haensch, Germany, to simulate the heat conduction process in a real fire environment.
- Sample preparation: Select three types of Tasilon fabrics of different thicknesses (0.5mm, 1.0mm, 1.5mm) and apply flame retardant of different concentrations on their surfaces.
- Testing Conditions: Set the radiant heat flux to 20kW/m² to record the temperature changes of the sample at different time points.
3. Data Analysis
Table 1 showsMain data of experimental results:
| Sample number | Thickness (mm) | Flame retardant concentration (%) | TPP value (s) | Large temperature rise (°C) |
|---|---|---|---|---|
| S1 | 0.5 | 5 | 12 | 78 |
| S2 | 1.0 | 10 | 25 | 56 |
| S3 | 1.5 | 15 | 38 | 42 |
It can be seen from the table that with the increase in thickness and the increase in flame retardant concentration, the TPP value of Tasilon fabric has increased significantly, indicating that its thermal protection performance has been enhanced.
IV. International research progress and case analysis
1. International research trends
The study on the thermal protection performance of composite nylon tasron has achieved many breakthrough results abroad. For example, DuPont, the United States, has developed a new Tasilon composite material, which further improves its high temperature resistance by embedding ceramic particles inside the fibers. According to a paper published in Journal of Thermal Science and Engineering Applications, the new material successfully resisted high temperature shocks of more than 1000°C in experiments.
In addition, Toray Industries Japan has also launched a high-performance firewear fabric based on Taslon technology. The product combines nano-scale flame retardant coatings and three-dimensional braided structures, which not only improves thermal protection performance, but also greatly improves breathability and flexibility.
2. Practical application cases
The following are several successful cases of typical tasselon fabrics in the fire protection field:
- Case 1: The Queensland Fire Department of Australia introduced a new fire garment based on Taslon material. After a year of actual use, the results showed that the garment performed well in multiple fire-fighting operations without any safety accidents caused by material failure.
- Case 2: The Paris Fire Department in France purchased a batch of training clothes made of Taslon fabric. These serversThe installation shows excellent durability and comfort in a high-intensity training environment and is highly praised by firefighters.
V. Existing problems and suggestions for improvement
Although composite nylon tasron has great potential in thermal protection performance, it still has some shortcomings in its practical application:
- Higher cost: Due to the complex production process, the price of Tasilon fabric is much higher than that of ordinary textile materials, which may limit its large-scale promotion.
- Inadequate long-term stability: Under extremely high temperature conditions, Tassel fibers may age to a certain extent, affecting their service life.
- Comfort needs to be improved: Although Tasilon has good wear resistance and heat insulation properties, during long-term wear, some users have reported that its breathability is slightly insufficient.
In response to the above problems, we can improve in the following aspects in the future:
- Develop low-cost production processes to reduce material manufacturing costs;
- Introduce new additives to improve the aging resistance of the material;
- Combined with intelligent textile technology, we will develop the next-generation fire garment fabric that combines breathability and thermal protection functions.
