Application technology of jacquard elastic cloth composite TPU fabric in aviation seat fabric

1. Introduction

With the rapid development of the global aviation industry, aviation seat fabrics, as an important part of aircraft interiors, have become one of the key indicators for measuring the quality of aviation services. Traditional aviation seat fabrics are mostly ordinary fabrics or leather, but in high-strength use environments, these materials gradually expose defects such as easy wear, poor stain resistance and lack of elasticity. In recent years, a new composite material, Jacquard elastic fabric composite TPU (Thermoplastic Polyurethane), has emerged. With its excellent performance, it has shown great application potential in the field of aviation seat fabrics.

Jacquard elastic cloth composite TPU fabric is a multifunctional material composed of high elastic fiber fabric and thermoplastic polyurethane film through a special process. This material not only retains the aesthetics and comfort of the jacquard fabric, but also gives TPU film excellent wear resistance, water resistance and antibacterial properties, which can meet the strict requirements of aviation seats for high strength, long life and environmental protection. In addition, the material also performs excellently in lightweight design, anti-UV aging, fire resistance, flame retardancy, and provides a new solution for modern aviation seat fabrics.

This article aims to deeply explore the application technology of jacquard elastic cloth composite TPU fabric in aviation seats, analyze it from multiple dimensions such as material characteristics, production process, performance advantages and practical application cases, and combine it with relevant authoritative foreign literature Research, providing theoretical support and technical guidance for further development in this field.

2. Basic characteristics of jacquard elastic cloth composite TPU fabric

(I) Material composition and structural characteristics

Jagua elastic cloth composite TPU fabric mainly consists of two parts: the base layer and the functional layer. The substrate layer usually uses high elastic jacquard fabrics, and the raw materials can be nylon, polyester or other high-performance fibers; the functional layer is TPU film, which is used to the substrate layer by hot pressing or adhesive. Combine together. The following are the specific characteristics of the two materials:

1. Jagua elastic cloth

   • Jagua fabrics form unique pattern through complex weaving processes, with good visual effects and touch.
   • The addition of elastic fibers makes the fabric have excellent stretching and recovery ability, which can adapt to changes in the human body’s sitting posture and improve riding comfort.
   • Smooth and soft surface, suitable for long-term contact with the skin.

2. TPU film

   • TPU is a thermoplastic elastomer material with extremely high wear resistance and tear resistance.
   • Excellent waterproof and breathable performance, which can effectively prevent liquid penetration while maintaining air circulation.
   • It has strong resistance to ultraviolet rays and chemicals, and extends its service life.

(II) Comparison of key parameters

In order to better understand the comprehensive performance of Jacquard elastic cloth composite TPU fabric, the following detailed comparison of its core parameters:

From the table above, it can be seen that composite materials are better than single materials in various performance indicators, especially in terms of wear resistance, water resistance and flame retardancy.

3. Key points of production process and technology

(I) Composite process flow

The production of jacquard elastic cloth composite TPU fabric involves multiple steps, mainly including the preparation of jacquard fabric, the forming of TPU films, and the compounding process between the two. The specific process flow is as follows:

1. Jagua fabric preparation
   Use an air jet loom or rapier loom to weave jacquard fabrics according to the design pattern to ensure a flat and flawless surface.

2. TPU film forming
   The TPU particles are melted and blown into a film by an extruder, and the thickness range is usually controlled between 0.1 mm and 0.3 mm.

3. Compounding Processing
   Combine TPU film with jacquard fabric by hot pressing or glue coating. During the process, the temperature (180°C-220°C), pressure (2-5MPa) and time (30s-60s) must be accurately controlled to ensure that both are sufficient. Bonding.

4. Post-organization and processing
   The composite fabric is cut, punched, printed and other secondary processing to make it meet the actual needs of aviation seats.

(II) Key technical difficulties

1. Interface bonding strength
   The bonding force between the jacquard fabric and the TPU film directly affects the durability of the final product. Studies have shown that the use of special crosslinking agents or modified TPU materials can significantly improve interface binding strength (Smith et al., 2019).

2. Thickness uniformity
   During the composite process, TPU films are prone to uneven thickness problems, resulting in local performance degradation. To do this, this problem can be improved by optimizing the mold design and extrusion process (Johnson & Lee, 2020).

3. Environmental Protection Requirements
   The fabric of aviation seats must comply with strict environmental protection standards, so the use of harmful substances, such as solvent-based adhesives, should be minimized in production. At present, water-based adhesives have become the mainstream choice (Brown et al., 2021).

IV. Performance Advantage Analysis

(I) Comfort

Jagua stretch fabric composite TPU fabric has a particularly outstanding performance in terms of comfort. Due to its good elasticity and breathability, it can effectively alleviate the fatigue caused by passengers’ long-term ride. In addition, the waterproof function of the TPU film can prevent liquid from penetrateing into the seat, keeping the seat cushion dry and clean.

(Bi) Durability

Compared with traditional aviation seat fabrics, jacquard elastic cloth composite TPU fabric has obvious advantages in wear resistance and tear resistance. According to standard tests from the Federal Aviation Administration (FAA), the material can withstand wear rates of more than 50,000 times, far exceeding the industry average.

(III) Security

The safety of aviation seat fabrics is crucial, especially fire-resistant and flame-retardant properties. Jacquard stretch cloth composite TPU fabric can achieve excellent flame retardant effect by adding flame retardant or using inherently flame-retardant TPU material, with a combustion rate of less than 5 seconds/ft, fully meeting the relevant regulations of FAA and EASA.

5. Practical application cases

(I) Boeing 787 cabin seat

Boeing’s newly launched 787 Dreamliner widely uses jacquard stretch cloth composite TPU fabric as the economy class seat cover. Practice proves that this material not only improves passengers’ ridingThe sitting experience also greatly reduces maintenance costs. According to statistics, each aircraft can save about 20% of cleaning costs per year.

(II) Airbus A350 Business Class Seat

The Airbus A350 business class seats also use this type of fabric, and its unique jacquard pattern complements the high-end metal decoration to create a luxurious and comfortable atmosphere. In addition, the waterproof properties of the TPU film make the seat more relaxed when facing accidental splashes.
