Performance
Performance standards set out the minimum physical requirements and standards of the fabric and finished item.
The following performance standards have been developed for bed linen:
Color fastness and print fastness tear strength seam slippage Dimensional change to washing pilling resistance Fabric construction color matching.
Color fastness to washing
The ratings are based on a grey scale. The grey scale ranges from 1 to 5 where:
1 = severe color change or stain 5 = no color change or stain.
Criteria Plain dyed Printed
Change of shade 4 4
Cotton stain 4 3.4
Color fastness to rubbing
The ratings are based on a grey scale. The grey scale ranges from 1 to 5 where:
• 1 = severe color change or stain • 5 = no color change or stain.
Criteria Plain dyed Printed
Dry 4 3-4
Wet 3 2-3
Color fastness to water and perspiration
Criteria Plain dyed Printed
Change of shade 4 4
Cotton stain 4 4
Nylon stain 3.4 3.4
Colorfastness to light
Determination of colorfastness to light is performed using an artificial light source (mercury vapor, tungsten filament or internally phosphor coated lamp).
The minimum exposure period is 60 hours.
Criteria Plain dyed Printed
Dark shade 5 5
Medium shade 4 4
Light shade 3 3
Print fastness after three washes
The print fastness-after-three-washes test is conducted by using the wash method in accordance with the Australian Standard AS 2001.5.4
Criteria Plain dyed Printed
Change of shade 4 4
Color matching
Color matching is the visual comparison of two samples, an original and a new sample, under natural or standard light conditions to determine whether there is any color variation between them.
Criteria Standard
Color matching 4.5
Tear strength
Tear strength is a test that determines how much force is required to tear a material.
Criteria Standard
Tear strength 5.5 N
Seam slippage
This is the measurement of seam separation, which occurs when sewn fabrics are pulled apart at the seam. Determination of seam opening due to the application of force in the transverse direction.
Criteria Standard
Seam slippage 65 N
Dimensional change to washing

Pilling resistance
The test measures the resistance of a material or fabric to pilling. Pilling is the formation of balls and fuzzing on the surface of a textile material or fabric. This test is based on ISO 12945: Textiles. Determination of fabric propensity to surface fuzzing and to pilling.
