Abstract
The present invention relates to textile fabrics and methods of manufacturing textile fabrics. Particularly, the invention comprises a method of producing a fabric, comprising the steps of (i) blending chemo mechanically felting fibers with non-felting fibers into a blended feed material, (ii) spinning the blended feed material into a blended yarn, (iii) producing a fabric comprising the blended yarn, (iv) subjecting the fabric to a first fabric treatment comprising a mechanical felting treatment; and (v) subjecting the fabric to a second fabric treatment comprising a chemical treatment of the fabric with an alkali, wherein the ratio of weight of the alkali to dry fabric weight is between 0.02 and 0.05, thereby obtaining increased air space in the resultant fabric.
