Definitions

• This invention relates to the treatment of woven, knitted or other fabrics and especially fabrics made with or containing threads or yarns composed of or COIIIPIIS- ing filaments or fibres of cellulose acetate or other cellulose esters or cellulose ethers,-- for the purpose of rendering them less liable to or immune from development of faults caused through lack of cohesion or low ooefiicient of friction existing between the threads or yarns of the fabrics at their points of crossing or interlooping.
• i5 term indicating that stresses in usage or in processes subsequent to weaving cause the threads of one component (i. e. the warp or weft) to slip over those ofthe other and produce, at the point of slipping, uneven distribution of the warp threads or Weftthreads.
• the fault is least observable in closely woven fabrics having a high number of reed and pick, and is most likely to occur in fabrics with a small number of crossings (i. e. points of contact of warp and weft) per unit area.
• the fault is commonly known as laddering and is caused by a line or series of loops in the fabrics on breakage of a loop or thread) becoming drawn out of or slipping out of the adjacent loops through which they are threaded in the structure of the fabric, owing to lack of cohesion or low coefficient of friction at the points of contact of the loops, so that a ladder-like defect results; while in thecase of warp-knitted fabrics the fault is commonly known as splitting and vis produced by the fabric splitting continuously along a wale of the fabric without tearing if a cuthappens to be made lengthwise in the middle of the Wale in a direction towards the beginning of the fabric, such splitting being likewise due to lack of cohesion or low 'coefficient of friction existing between the threads of the fabric.
• Woven, knitted or other fabrics,-and especially fabrics made with or containing yarns or threads composed of or comprising filaments or fibres of cellulose acetate or other cellulose esters or cellulose e thers are subjected to simple or repeated application, by impregnation with strong aqueous solutions or dispersions of one or more bodies known to have a solubilizing or dispersing power for water-insoluble or relatively water-insoluble dyestufis, that is to say a power of rendering waterinsoluble or relatively water-insoluble dyestuffs soluble or capable of high dispersion in water.
• such bodies are referred to as dispersing agents and their aqueous solutions and dispersions are referred to collectively oleic, stearic, palmitic, and the other higher fatty acids and sulphonated or other derivatives thereof containing salt-forming, groups (e. g. the sulpho group or the carboxyl group or both sulpho and carboxyl groups) and soluble salts of such acids or derivatives, for instance their alkali or ammonium salts or mixtures of two or more of such acids and/or derivatives and/or salts; for the sake of brevity all such acids, ,derivativcs and salts and mixtures are herein included in the term body-of oily or fatty characteristics.
• groups e. g. the sulpho group or the carboxyl group or both sulpho and carboxyl groups
• soluble salts of such acids or derivatives for instance their alkali or ammonium salts or mixtures of two or more of such acids and/or derivative
• Carbocyclic compounds containing in their structure one or more salt-forming groups such as sulphonic, carboxyl or hydroxyl groups, whether the compound contains only one kind of these groups or different kinds of these groups at the same timeand sodium or other soluble salts of said compounds; or mixtures of any of such carbocyclic compounds and/or salts, or mixtures of one or more thereof with one or more of the aforesaid bodies of oily or fatty characteristics.
• carbocyclic compounds and salts may be mentioned naphthenic acids, naphthene sulphonic acids, or other carboxylic or sulphonic acids of the cycloparafiins; henols, sulphonic acids, carboxylic acids, p enolsulphonic acids or other derivatives of the benzene, naphthalene or anthracene series containing one or more salt forming groups, or other derivatives of saturated or non-saturated cyclic hydrocarbons containin one or more salt-forming groups, and so ium or other soluble salts of any of these compounds.
• Sulpho aromatic fatty acids such for instance as sulpho-benzene stearic acid (Twitchell reagent), or derivatives thereof such as sulp'hophenol stearic acid, sulphonapthalene stearic acid, sulphobenzenericinoleic acid, sulphophenolricinoleic acid, sulphonaphthalene ricinoleic acid, or sodium or other soluble salts of such acids or derivatives, or mixtures of any of such and/or derivatives and/or salts.
• sulpho-benzene stearic acid Tewitchell reagent
• derivatives thereof such as sulp'hophenol stearic acid, sulphonapthalene stearic acid, sulphobenzenericinoleic acid, sulphophenolricinoleic acid, sulphonaphthalene ricinoleic acid, or sodium or other soluble salts of such acids or derivatives,
• Soluble resin soaps or sodium or other soluble salts or soaps of resin acids.
• the salts and the mixtures of the free acids or saltforming c'ompounds with the salts whether of the same or of different acids or salt forminglpompounds are especially useful.
• the oods may be subjected to the impre ation y any suitable means, but I have mind the machine known as the pad ding mangle to be particularly suitable.
• This a paratus provides for the passage of the fa ric' through the strong aqueous solution of. one or more dispersin agents, followed by a squeeze between ro lers, so that excess. of liquor is expressed, rendering subsequent rollin vup or other manipulation more easy.
• e'aqueous solutions may be applied at any suitable temperatures and concentrations, but I have found the best results to be achieved with hot li uors at about (3., or, where the fabric W111 withstand themboiling temperatures.
• the goods are preferably piled or rolled up to avoid evaporation and cooling and left for a number of hours, conveniently overnight in commercial working, then after this maturing period, scoured as desired, and dried, or passed direct to any such subsequent processing as dyeing or printing.
• the impre nation process may be repeated in Wine case after scouring off the first time, the fabric is preferably dried in open width, as for instance on the well known continuous tentering machine, before the second impregnatlon.
• the'process of the present invention is of especialvalue for treating fabrics made with or containing yarns or threads composed of or comprising filaments or fibres of cellulose all of which are hereinafter in the claims referred to as fabrics comprising organic substitution derivatives of cellulose acetate or other esters or ethers of cellulose, it may with'advantage be applied to fabrics made with or containing yarns or threads composed of or comprising other filaments are then passed III or fibres, for instance natural silk, artificial silks of the cellulosic type, (e. g. cuprammonium silk, viscose silk, nitrocellulose silk and the like), cotton, wool and so forth.
