In general, clothing should be tested for colour fastness before using bleach or other cleaning products. [3] Lightfastness, wash fastness, and rub fastness are the main forms of colour fastness that are standardized. The light fastness of textile dye is categorized from one to eight and the wash fastness from one to five, with a higher number ...
A rating between 0 and 8 is awarded by identifying which one of the eight strips on the bluewool standard card has faded to the same extent as the sample under test. [4] [5] Zero denotes extremely poor colour fastness whilst a rating of eight is deemed not to have altered from the original and thus credited as being lightfast and permanent.
For example, if the lightfastness of the colourant is indicated to be 5 on the Blue Wool scale, it can be expected to fade by a similar amount as the strip number 5 in the Blue Wool test strip set. The success of the test can be confirmed by comparing the test strip set with the reference set that was stored protected from the light. [12] [13]
AATCC published its first four color fastness test methods in 1923. 1964. AATCC built and moved into the Technical Center in Research Triangle Park, North Carolina in 1964. 1965. AATCC began conducting test method training programs in 1965. Durable press testing was the most popular training initially offered at the Technical Center. 1966
Fabric testing includes measurements such as fabric weight, fabric width, shrinkage testing, colour fastness to washing, fastness to light, pilling, tearing and bursting strength, etc. The primary consideration in fabric selection is the end use. The fabric needs vary greatly depending on the application.
Cotton is an absorbent fibre which responds readily to colouration processes. Dyeing is commonly carried out with an anionic direct dye by completely immersing the fabric (or yarn) in an aqueous dyebath according to a prescribed procedure. For improved fastness to washing, rubbing, and light, other dyes such as vats and reactives are commonly ...
We put the best air purifiers from Lenovo, Honeywell, Winix, and more to the test to see which held up best (and actually purified the air for you). See what our product scientist has to say.
A modern umbrella fabric has specific requirements for colour fastness to light, water and wet rubbing, and permeability. Serviceability in textiles or Performance is the ability of textile materials to withstand various conditions, environments, and hazards.
