Abstract
Garments are constructed from lyocell fabric which has been resinated using a textile resin having just two groups per molecule which can reactively cross-link with cellulose molecules of the lyocell fabric then causticised by application under tension of an aqueous solution of sodium hydroxide, and the constructed garments are dyed in a garment dyeing operation. Garments can be produced by this route which retain a smooth, evenly-dyed appearance with unpuckered seams and minimal creasing and so present a desired formal look, as distinct from the casual look imparted by the effects of fibrillation normally produced when lyocell garments undergo garment dyeing.
