Fibro and Fibrolane in the Carpet Trade with particular reference to Dyeing
ABSTRACT The impact of man-made fibres on the carpet trade is discussed, and the desirable attributes of a carpet fibre are suggested. The properties and the performance of viscose rayon staple (Fibro) and regenerated protein staple (Fibrolane) are then considered in detail, some indication being given of the relative advantages of these fibres as well as any apparent disadvantages. The methods being developed to overcome these disadvantages include modifications to fibre structure as in crimped Fibro and Fibre M 55 and also treatments designed to reduce rate of soiling. Suggestions are then made regarding the composition of man-made fibre blends and reference is made to spun-dyed staple.The scouring and the dyeing of blends consisting of Fibro and/or Fibrolane are then considered, detailed methods and selections of dyes being given for the various staples and yarns. Particular reference is made to the effect of denier on dyeing rate as it affects both staple and yarn. The absorption of direct dyes by protein blends containing Fibro is shown to follow similar lines to that by Fibro itself, but certain special considerations apply. Finally, brief reference to the dyeing of tufted carpets is followed by a summary of progress.
