The recent launch of woven denim fabrics containing Merino wool, which are at price points attractive to a wider market than previous wool/cotton denim products, has created interest in a knitted version.
A relatively new product, Wool Denim (Knitwear) is popular for ladies wear because of its figure-hugging properties and comfort in wear. The fabric also can be used for men’s trouser bottoms in a higher density fabric.
The need to use an Indigo-dyed wool yarn in the knit product has, until this innovation, been a barrier to merino wool-containing knitted-denim.
True Indigo-dyed wool yarns are expensive to produce because of the dip-dye technology which needs very long processing runs to be economic.
With the advent of cold-dye reactive dyeing systems for cotton and now wool it is feasible to create denim-like wool yarns which, when knitted into denim jersey constructions, can create knitted denim looks in pure wool or wool/cotton blends.
The fabric structures are normally based on a type of terry, single fabric to enable woven effects to be created. The special dyeing process permits fading of colour during garment washing and development of the classic denim look.
