Knitted fabric tends to change dimensions in length and width after being taken off the machine. The more favorable conditions for fabric’s relaxation provided during washing. Change of dimensions after knitting can create major problem in garments and fabrics especially. Those produce from hydrophilic fibers such as wool and cotton. Knitting from

Thermoplastic fiber and synthetic fibers such as nylon and polyester can be heat set to shape or to dimensions that are retained unless the setting conditions are exceeded during washing and wearing.

Alkylphenols (APs) and Alkylphenol Ethoxylates (APEOs)

Alkylphenol Ethoxylates are considered to be harmful and toxic to the environment and possible endocrine disrupters. The most common usage is in detergent products and emulsifying agents. The second most common use is in textile processing (in particular with fibres such as linen and silk, whose naturally occurring gums and resins make them difficult to wet out) where it is used in various textiles auxiliaries including wetting agents and in the manufacture of water based pigment pastes to improve pigment dispersion.

The use of APs and APEOs specifically containing Octyl Phenols (OP) & Nonylphenols is restricted in all areas of David Howard production.

Nonylphenol Ethoxylate (NPEO), Octylphenol and their Ethoxylates (Alkyl Ethoxylates)

David Howard do not accept the use of any of the above chemicals in the production or processing of our goods.


This method has been developed as there are no national or international standards based on this method at the present time.


To determine the degree of appearance retention after machine washing.


A finished/completed garment is washed and assessed against an unwashed garment for deterioration in appearance.


  1. Automatic washing machine as specified in BS EN 26330:1994
  2. Commercially available detergent
  3. Grey scales for assessing change in colour as BS EN 20105 A2

  5. Drying facilities as applicable to garment care label, flat or hang or tumble dryer as             specified in BS EN 26330:1994


It is not necessary to condition samples nor carry out the testing or assessment in a standard atmosphere. Ordinary room conditions are satisfactory provided the correct procedure is followed.


Minimum of two finished/complete garments


Make wash load up to 2kg

  1. Place one garment in the washing machine

  1. Run the machine (select programme to match garment care label).
  2. Dry according the garment care label instructions
  3. Compare the washed specimen with the unwashed duplicate in the light cabinet             under artificial daylight D65.
