Definitions

• the present invention relates to finishing treatments of fabrics of mixtures of cellulosic and polyester fibers and/ or cellulose tri-acetate.
• reactive dyes are used for the natural cellulosic fibers such as cotton or the regenerated cellulosic fibers such as viscose rayon.
• Disperse dyes are used for the coloration of polyester fibers and/or cellulose tri-acetate fibers.
• the stiffening or crease-resisting resin is included to inhibit swelling of the cellulosic fibers'other than cellulose tri-acetate, such ascotton or regenerated cellulose fibers such as viscose rayon.
• the polyester fiber may be of homopolymer's-uch as polyethylene terephthalate. or a copolymer such as polyethylene terephthalate with a minor proportion of poly ethylene isophthalate.
• Suitable silicone water-proofing compositions for use with the process are those known toimpartwater-re pellency to textile materials, such as, for example, an emulsion of methyl hydrogen polysiloxane.
• the inorganic bases sodium sesquicarbonate and sodium bicarbonate,
• alkaline catalysts which may be used, avoiding bath instability.
• Sodium bicarbonate is preferred as it gives good results.
• a disperse dyestuif a dyestuif which is applied as a suspension with a dispersing agent and fixed to the fiber by the application of heat.
• the dyestuffs sold under the registered trademarks Dispersol and Duranol are suitable for use in the process of the invention.
• the heat treatment is carried out at a temperature which is at the same time high enough to bond the disperse dyestufl and to cure the silicone water-proofing composition.
• the preferred range of curing temperatures is 220 C., and that of curing times 15 seconds to 5 minutes.
• the amount of silicone composition on the finished fabric is preferably from 0.5 to 5% by weight of the fabric.
• a shade change normally occurs with disperse dyestuffs on the application of silicone water-proofing compositions. This is largely overcome when using the process of the present invention since the dyer matches to the silicone composition finished shade.
• the process of the invention gives fast-dyed, waterrepellent fabrics which are particularly suitable for rainwear.
• Suitable cellulose-reactive stiffening or crease-resisting resins include melamine formaldehyde, dimethylol-ethylene urea, triazone and methylated urea formaldehyde resins.
• the resins should, in the presence of a suitable alkaline catalyst, prevent swelling without inhibiting water-proofing with the silicone compositions and impart crease-resisting properties to the cellulosic fibers, other than cellulose tri-acetate.
• Suitable cellulose-reactive dyestuffs are those in which the reactive component is a cyanuryl chloride; i.e. these dyes are derivatives of 1:3:5 triazine which contain reactive chlorine atoms attached to the carbon in the triazinyl ring. They are described, e.g. in the paper The Reactions of Cold-dyeing Procion Dyes With Cellulose by T. L. Dawson, A. S. Peru and C. Preston published in the Journal of the Society of Dyers and Colourists, vol. 76 (1960) from p. 210 onwards. Reference also may be made to the description of these dyes in British Patents 797,946 and 798,121, viz.
