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.

Lyocell fabric treatment to reduce fibrillation tendency

Fibre treatment

Dyeing of cellulose

Fibre treatment method

A process is disclosed for providing a solvent-spun cellulose fibre with a reduced fibrillation tendency. The fibre is treated with a chemical reagent, preferably substantially colourless, having 2 to 6 functional groups reactive with cellulose, suitably dissolved in an aqueous solution.

Process for reducing the fibrillation tendency of solvent-spun cellulose

Regenerated cellulose fiber with a reduced tendency to fibrillation can be prepared by treating never-dried fiber with an aqueous solution or dispersion of a polymer having a plurality of cationic ionisable groups. Suitable polymers include those carrying imidazoline and azetidinium groups. The fiber may additionally be treated with an aqueous emulsion of an emulsifiable polymer.
