Faded and washed out effects are popular in casual garments. When garments fade during washing they do so unevenly, especially on seams and raised areas, and it is this effect that is reproduced in Vintage. This is a surprisingly difficult effect to create in wool which is renowned for its vivid and vibrant and durable colours. The classic approach to creating this look in wool is to simply use pigments which can be bonded to the fibre with binders, but this approach is characterised by poor handle and poor rubbing fastness.
Two technologies are available.
For knitted garments, the unlevelness of washed garments can be created by unlevel dyeing associated with applying the dyes too quickly. By using less levelling agent and allowing reactive dyes to exhaust onto easy care knitwear within 10 to 15 minutes the dye tends to exhaust more deeply in easily accessible regions of low yarn twist or fabric density. However, the effect can be made to be uniform over the whole garment. Once the dyes are exhausted the dyes can be fixed using normal boiling times and if the correct clearing cycle is used normal levels of washing and rubbing fastness can be obtained.
For woven fabrics or hosiery yarns, the approach is to use low-temperature reactive dyes that are normally applied to cotton. Being the wrong type of dye for wool they are not so easily fixed to the fibre. Thus, during subsequent industrial washing of the garments, some of the dye is removed in exactly the same way as for cotton materials leading to the 'faded' look of an old or vintage garment.
