A telephone cable comprises a core consisting of stranded paper insulated conductors 10 bound with paper tape 12, an inner jacket 14 formed by lengthwise wrapping a metal tape coated on at least the eventual inside surface with plastics material chemically bonded to the metal, the edges being joined together as shown at 6-6, and an outer jacket 34 formed by lengthwise wrapping a metal tape coated on both sides with plastics material, the edges overlapping as shown at 7-7. A plastics outer sheath 42 is bonded to the plastics material on the outside of jacket 34. The two composite jackets may be applied continuously to the core (Fig. 1, not shown). The inner jacket 14 is preferably formed from thin metal foil coated on the eventual inside surface with a polyethylene which incorporates carboxyl groups and on the other surface with a material of higher softening point, e.g. polyethylene terephthalate, polypropylene or high density polyethylene, to prevent the outside of jacket 14 bonding to the inside surface of jacket 34. As jacket 14 is wrapped round the core, the abutting inside edge portions are softened with hot gas (Fig. 3, not shown), pressed together (Fig. 4, not shown) and folded over. Jacket 34 is formed from relatively thick metal coated on both sides with preferably the same carboxyl-containing polyethylene as the inside of jacket 14. Metal to plastics ratio in jacket 34 may be about 2 to 1 as compared with about 1 to 8 in jacket 14. The metal may be aluminium, copper or steel, a steel layer also providing magnetic shielding. Outer jacket 42 is preferably polyethylene.

Alternatively a mat of cellulose acetate fibres may be sandwiched between layers of cellulose acetate woven fabric, and, if desired outer layers of cellulose acetate fibre mat may be applied; or layers of high-tenacity cellulose acetate fabric may be applied on each side of a glass fibre mat. The product may be translucent, or dyes or pigments may be incorporated in the binder or in the thermoplastic fibres. The binder may be an unsaturated polyester to which a polymerizable liquid may be added, a polymerizable unsaturated alcohol ester of an unsaturated acid, a polymerizable unsaturated alcohol polyester of a polybasic acid, or a polyhydric alcohol ester of an unsaturated acid. Lists of each type of binder are given, typical examples being ethylene or diethylene glycol maleate resin with styrene or vinyl acetate, a polyester resin from ethylene glycol, maleic and phthalic anhydrides with diallyl phthalate, vinyl acrylate, diallyl carbonate, ethylene glycol diacrylate.

Title: Improvements in or relating to the colouration of textile materials
IPC: D06P3/42
Filed: 1934-10-01
Abstract: Cellulose ester or ether textile materials are coloured uniformly, i.e. over the whole surface, by mechanical impregnation with a liquid preparation containing a water-insoluble dyestuff having direct affinity for the material, at least 90 per cent of the liquid content of the preparation being water or another non-solvent for the material, followed by rapid drying with the aid of heat but without steaming or ageing.  The impregnation may be effected, for example, by padding or spraying or by a wick contacting with a travelling yarn or filament.  Specified liquids, in addition to water, which are non-solvents for the materials, are benzene, toluene, xylene, tetralin, ethylene dichloride, dichlorethylene, trichlorethylene, perchlorethylene and methyl, ethyl, propyl, isopropyl, butyl and amyl alcohols.  Specified dyestuffs are those of the aminoanthraquinone, azo, nitrodiarylamine and nitroaminodiaryl series and these may be present as dispersions obtained with the use of the dispersing agents of Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737 or 323,788, [all in Class 15 (ii)]. Thickening agents, such as gum arabic, gum tragacanth, gum Niger, gum tragasol, dextrin or British gum may also be present in the preparations, and the presence of a small proportion of glycerol or other hygroscopic substance or of sodium acetate or silicate, sodium or potassium oleate, or other substance capable of increasing the absorptive capacity of the materials (cf. Specification 415,094) is advantageous.  Small amounts of solvents or swelling agents, such as ethyl lactate, diacetone alcohol, ethyl alcohol, diethylene glycol and thiodiglycol may also be present.  In an example, a cellulose acetate woven fabric is padded at 70 DEG  C. with an aqueous liquor containing gum arabic and 1 : 4-di-(ethanolamino) - 5 : 8 - dioxyanthraquinone pasted with diethylene glycol and turkey red oil and the padded fabric is dried rapidly by passing it in contact with steam-heated drums, washed, dried and finished; alternatively, the padding liquor may be a solution of 1-amino-4-oxyanthraquinone in perchlorethylene. Specification 314,208, [Class 15 (ii)], also is referred to.
