Title: Dyeing synthetic fibres
IPC: D06P5/28
Filed: 1974-11-20
Abstract: Colouring or tinting synthetic fibres by contact with webbing or film impregnated with an excess of a dye compatible with the synthetic fibres conserved under conditions of temp. and pressure which ensure some dye transfer. The process is esp. for identifying and/or counting synthetic fibres (I) present as an impurity or low level additive in cloths or fabrics made primarily of other materials, esp. where (I) comprises polyester, polypropylene, cellulose acetate, acrylic, polyurethane or PVC based fibres, esp. in textiles made from recovered wool or cotton waste. Also for colouring composite textiles by contacting them with successive mats sealed with dyes and/or pH conditions to suit the individual component fibres or filaments, to produce uniform colouring of dissimilar materials. Colouring treatment is selective, introduces relatively little resistance into the bulk of the material being treated, reducing post drying costs.
