Proven quality: textile tests for professionals
In this post we’re having an in-depth rundown through some of the tests FR-One fabrics undergo in our search for the highest quality textiles. Read on to discover exactly what these tests are and what your fabric’s test results mean.
When you are selecting something, you naturally want to know that it will stand up to use. The same is true of fabrics. Before making an investment in textiles, make sure that your prospective fabrics have undergone a variety of tests. This will ensure that your fabrics will not only perform well at the beginning of their use, but that their quality will stand the test of time. ‘High quality’, after all, is not an easy standard to achieve. For fabrics, ‘high quality’ means that they have passed through a myriad of textile tests, and proven to perform. The tests we’re looking at today are:
1. Fabric rub counts, and the Martindale and Wyzenbeek tests
2. All about fabric pilling tests
3. Washing tests: colourfastness, fibre stability, shrinkage, aspect change
4. Light fastness in textiles
Not for the faint hearted.
What is a fabric rub count?
Textile engineers assess the resistance of fabric to abrasion using the Martindale wear resistance test (ISO 12947-2, EN 14465).
HOW IT WORKS: Inside the Martindale machine, a fabric sample is rubbed repeatedly by a small disc of worsted wool or wire in a figure-of-eight pattern while being assessed by engineers at certain intervals.For us here at FR-One, a pilling scale grade of minimum 3-4 at 5000 rubs means that our fabric will stand the test of time.
Our fabrics also undergo a brush pilling test (ASTM D 3511). The procedure is:
1. Fabric specimens are brushed with a nylon brush
2. Then they’re rubbed against each other face-to-face
Samples undergoing a brush pilling test are assessed and graded and given a score, not unlike the pilling test.
A note on the Wyzenbeek test
All about fabric pilling tests
HOW IT WORKS: A fabric sample is placed in the testing chamber together with a standard blue scale reference fabric made of wool.
Washing tests: colourfastness, fibre stability, shrinkage, aspect change
These specifically include colourfast tests, ironing and washing tests and tests for dry-cleaning as well.
Properties like colourfastness are very important to study from different angles: your fabric might hold its colour well under a washing test, for example, but that doesn’t mean it’ll hold up under a rubbing test…which is why you need both.
HOW IT WORKS: First, textile engineers measure the testing fabric in both the warp and weft directions.
The fabric is measured again after washing. This washing and measurement takes place at a sliding temperature scale range.
After washing and drying, the colour of the fabric is evaluated using the grey scale (grade 1 to 5) to see if it’s changed in any way. The fabric is also re-measured to check if any shrinkage has occurred, or if the fabric’s original look has changed at all.
All new 2018 FR-One collections stand up to washing at at 71⁰C (160°F).
This high temperature is the American Hospital Washing Standard (AATCC96), because after all, the best way to keep interior décor fabrics clean and free of germs is by washing at a temperature high enough to remove allergens and kill any bacteria that may be present.
Because FR-One fabrics surpass American Hospital Washing Standards, they are the go-to choice for interior designers working not only in residential settings, but also in the healthcare and hospitality sectors (including on cruise ships. FR-One is IMO certified).
Light fastness in textiles (CFL)
We perform ultraviolet (UV) testing to understand how fabrics perform under the damaging effects of prolonged exposure to ultraviolet light.
Lengthy exposure to UV rays can cause a variety of different issues when it comes to textiles.
Most people think of fading first, but exposure to UV light can damage fabrics in other ways too, such as the breakdown of the fibres, which could lead to complete disintegration of the fabric structure through reduction in the core fabric strength.
The Blue Scale measures and calibrates the permanence of colouring dyes.
Both fabrics are exposed in a testing chamber to the equivalent of sunlight continuously for three months (in a simulation of the sun’s ultraviolet rays within a controlled laboratory setting).
Then they are compared to each other and rated on a grade from one to eight. The higher the rating, the better the fabric will perform to daylight.For FR-One fabrics, a colourfastness to light of blue scale grade 4 is good, and anything surpassing this is considered excellent.
Fabulous fabrics: no shrinkage, or fading, or wearing out, or pilling
We take all international standards and regulations into account when developing our fire retardant fabrics. You want your product to be versatile and perform at its best no matter wherever it is, after all.
As a result, FR-One fabrics are tough enough to withstand all kinds of functions without them shrinking, fading, wearing out or losing their fire resistant properties.
This is our guarantee.
We also promise that your fabrics will remain as vivid and luscious as they were the first time you saw or touched them. There is no point in doing something unless you do it properly.
