JIS L1099 Laminated fabrics Water vapour transmission testing
The JIS L1099 standard is a critical method used to determine the water vapor permeability of laminated fabrics. This test is essential for ensuring that textiles meet specific performance criteria, particularly in sectors where breathability and comfort are paramount. Laminated fabrics consist of two or more layers bonded together using adhesives or other techniques to create composite materials with enhanced functionality.
The JIS L1099 test evaluates the ability of these laminates to permit water vapor to pass through while preventing liquid water from penetrating. This property is crucial for applications such as medical garments, sportswear, and protective clothing where breathability directly impacts user comfort and safety. The standard specifies detailed procedures for specimen preparation, testing apparatus, and evaluation criteria.
The test involves measuring the rate of water vapor transmission through a specified area of laminate over a set period under controlled conditions. These conditions include temperature, humidity, and pressure to simulate real-world usage scenarios accurately. Compliance with JIS L1099 ensures that products meet industry standards for breathability, which is vital in maintaining user health and satisfaction.
Our testing laboratory adheres strictly to the guidelines set forth by JIS L1099, ensuring accurate and reliable results.

Scope and Methodology
The scope of JIS L1099 Laminated fabrics Water vapour transmission testing encompasses a detailed methodology aimed at evaluating the breathability of laminates used in various applications. This standard applies particularly to products intended for medical, sports, and protective clothing sectors where maintaining optimal levels of moisture management is essential.
The test procedure involves placing a specified area of laminate between two chambers that are then adjusted to maintain specific temperature and humidity conditions. One chamber contains dry air while the other houses humidified air. Over time, water vapor moves from the wet side towards the dry side through the laminate sample. The rate at which this occurs provides valuable insights into the material's breathability.
Key parameters include the initial mass of the specimen before testing, the duration of exposure to defined environmental conditions, and the final mass after the test period has elapsed. These values form the basis for calculating water vapor transmission rates according to JIS L1099 criteria.
| Parameter | Description |
|---|---|
| Initial Mass | The starting weight of the laminate before testing begins. |
| Dew Point Temperature | The temperature at which condensation starts forming in the humidified chamber. |
| Humidity Level | The relative humidity percentage maintained within each chamber during testing. |
| Testing Duration | The length of time over which water vapor transmission is measured. |
| Final Mass | The ending weight of the laminate after exposure to specified conditions. |
To ensure accurate measurements, all instruments used must adhere strictly to JIS L1099 requirements. Our laboratory uses high-precision scales and temperature-controlled chambers calibrated according to international standards such as ISO 8573-2:2014 and ASTM E96.
Our team of experts meticulously follows each step outlined in the standard, ensuring compliance throughout every aspect of the testing process. This dedication guarantees that clients receive precise results aligned with industry best practices.
Competitive Advantage and Market Impact
The ability to accurately measure water vapor transmission (WVT) is crucial for manufacturers aiming to stay ahead in highly competitive markets. Compliance with JIS L1099 not only ensures that products meet regulatory requirements but also enhances their reputation among consumers seeking high-quality, comfortable clothing.
For businesses operating within the medical sector, demonstrating adherence to international standards like JIS L1099 can significantly boost credibility and trustworthiness. In markets where comfort and safety are paramount—such as sports apparel or protective gear—breathability plays a vital role in user satisfaction. By offering products that consistently pass rigorous tests, companies can differentiate themselves from competitors who may not adhere to such stringent guidelines.
Moreover, achieving compliance with JIS L1099 provides manufacturers with an edge over others by ensuring consistent performance across all batches of production. This consistency is particularly important for large-scale operations where batch-to-batch variations could lead to discrepancies in product quality. Ensuring uniformity through standardized testing processes helps maintain brand integrity and customer loyalty.
From a business perspective, compliance with JIS L1099 opens doors to new markets that demand stringent quality controls. It also facilitates smoother interactions with regulatory bodies responsible for overseeing textile standards globally. Ultimately, this standard contributes positively towards long-term profitability by fostering sustainable growth based on reliable product performance.
