Abstract

A continuous integrated process for the colouration of filaments melt spun from synthetic linear polymers comprises applying a dye or optical whitener dissolved without dispersing agents or diluents in at least one hot organic substantially non-aqueous solvent to the undrawn filaments having a birefringence of less than 10 X 10-3 under conditions such that penetration of the dye into the filaments is 60% of the cross-sectional area or more followed by drawing the filaments to 3-6 times their original length. In a preferred embodiment of the invention <FORM:0921125/IV(a)/1> where Cf, the concentration of dye in the fibre, is 2 or more, Cs, the concentration of dye in the solvent, does not exceed saturation and K is a constant, preferably between 0,2 and 1,6. Specified solvents are ethylene glycol, diethylene glycol, polyglycols and ethylene oxide condensates of molecular weight 200-6,000 and their esters and ethers, dimethyl and diethyl sebacate, oleic acid, mesitylene, triphenyl phosphate and glycerol or mixtures thereof all of which are suitable for use at 100 DEG -150 DEG C. Additionally specified are trichlorethylene, carbon tetrachloride, acetone, benzene and glacial acetic acid which are suitable for use at or near their boiling points. The preferred contact time in the solution is 5-15 seconds. The linear polymers may be polyolefines, polyamides and polyesters including polyethylene terephthalate and its copolymers with polyethylene sebacate. The classes of dyestuff suitable are the unsulphonated bases of acid wool dyes, oil soluble or vat pigments and especially disperse dyes. The filaments are preferably treated as a tow which may be impregnated with the dye solution in a pad-mangler controlled to an increase in weight of 25-35% and thereafter maintained at an elevated temperature for the required dyeing time. A suitable apparatus for the process comprises a pad-mangling system for applying the dye solution and a draw frame for drawing the filaments, side plates and means for heating and maintaining the padding bath at the correct temperature and level, the feed rolls of the draw frame being driven at the same speed as those of the pad-mangler while the draw rolls are driven 3-8 times faster than the feed rolls with means for heating the filaments and means for removing excess dye solution and means for winding or forwarding the dyed and drawn filaments. Preferably there is a thermostatically controlled heater tube vertically below the pad mangle whose atmosphere may be kept saturated with solvent by a drip device. After removal of excess dye liquor the wet filaments may be crimped, dried and heat-set in a relaxed condition and, if desired, cut into staple fibre lengths. Examples of producing coloured filaments of polyethylene terephthalate are given.
