TEXTILE REPORT

Fabric quality evaluation to ISO Standards :


An excellent fabric cannot be just waterproof (it would be unsuitable as a camping fabric); one of its’ main properties must be breathability: Each square centimeter of fabric shall contribute to the natural exchange of air. This fundamental principle should be adhered to, especially in environments with small volumes of air (such as a tent), to prevent condensation from forming, and therefore, a heat reduction occurring within. By allowing a natural flow of air, containing moisture, generated by the tent’s occupants, maximum comfort can be achieved.
In the case of drastic temperature change, the natural increase of condensation can be reduced by using the openings of the tent.
We advise against using artificial instruments such as fans, dehumidifiers, or other commercially provided appliances. To scientifically evaluate a fabrics qualities, subject to its uses, we have to consider the following:
1. The ratio between impermeability (maximum column of water the fabric is resistant to, according to ISO 811) and breathability (air permeability according to ISO 9237), calculated with reference to dimensions and inner volumes of the tents (habitable area) and area (in square meters) of the textile surface: basic criteria for a healthy environment.
2. Specific purpose of the fabric: for example, the tents roof or side walls, including stresses and movement the fabric is subject to as well as weather and climate influences.
3. Stretch (ISO 5081) and tear-resistance (ASTM D1424)
4. Color Stability (ISO 105B04) considers weather and climatic conditions, including the reaction of a combination of fabrics and threads.
5. Light Resistance (ISO 105B02) effectiveness against direct sunlight and artificial lighting.
6. Weight (ISO 3801) of fabric for suitable waterproofing, not forgetting the weight of the tent/volume ratio when folded for transport or erection.
7. Cleaning and Maintenance: including resistance to dirt and mildew.

Many fabric suppliers say their fabric is breathable but you can use the following procedure to make sure it is. Approach the tent and press a small area of fabric over your mouth. When breathing out, if you feel the airflow in the palm of your hand, the fabric is considered breathable.
Another critical factor is the water vapor transmission rate through the fabric, which should not be lower than 350 g/m²/24hrs. High breathability and excellent water vapor transmission rate can effectively limit moisture forming inside the tent, thus keeping your environment fresh and healthy. Therefore, choose carefully!
