Definitions

• the textile material After weaving, the textile material is immersed in a halogenated hydrocarbon solvent which dissolves and removes the textile assistant from the woven textile. Thereafter, any halogenated hydrocarbon solvent adhering to the woven textile is removed by contacting the textile with hot wafer or steam.
• the solvent is removed by immersion of the textile in a hot water bath which also contains a dyestutf for the textile material.
• This invention relates to a process for the treatment of textile materials and more particularly to process improvements or modifications which can be used in conjunction with the securing of textile materials with organic solvents.
• textile assistants for example sizes, lubricants, spin finishes or other materials
• Such textile assistants may be applied in the form of a solution or dispersion or a melt as may be appropriate.
• Suitable textile assistants for application to the textile material before weaving or during weaving include any of the conventional materials which are soluble or dispersible in organic solvents, for example, oils, fats and waxes, and also polymeric materials of various types, for example, polyvinyl acetate types, polyvinyl acetals, polymethyl methacrylate and chlorinated rubber. These may be applied to textiles materials in the form of yarns, fibres, filaments, and the like before weaving. Many materials which have valuable properties as textile aslsrstants, particularly in connection with some or the newer synthetic textile materials, are seldom used at the present time because it is so difiicult to remove them by aqueous scouring after the weaving operation is complete. In the process of our present invention, we find that removal after weaving present no difficulty when the solvent scouring technique is used. Parafiin waxes may be mentioned in particular as an example of a lubricant of this type.
• the textile assistants e.g. sizes
• the textile assistants will be removed as part of the solvent scourmg operation, thus eliminating the need for a separate scouring step. If desired, they may be recovered from the organic solvent solutions produced in the scouring operation.
• the solvents and techniques which can be used for the solvent scouring stage may be particular any of those described more fully in UK. specifications Nos. 812,894; 916,338; 747,481; 749,705; 812,893; 844,943; 825,402 and patent applications Nos. 38,216/ 64 and 9,975/65.
• the solvent may be in particular trichloroethylene, perchloroethylene, 1,1,2-trichloro 1,2,2 trifluoroethane or mixtures thereof.
• the choice of solvent to be used depends very much upon the particular textile material concerned and the solvent is best chosen so that its solvent properties and boiling point are such that its use will not adversely elfect the textile material.
• a low-boiling solvent for example 1,1,2 trichloro 1,2,2 trifluoroethane, in the case of textile materials which are particularly sensitive to heat or solvent action.
• the dyeing stage may involve the use of any of the conventional dyestuffs and dyeing assistants known in the art, and these may be selected appropriately to the frabic blend concerned.
• the temperature of the flash-off bath, and the time for which the textile materials are immersed in it may be varied within wide limits as may be appropriate to the particular materials involved.
• the textile materials containing the dyestuff may be subjected to any of the known procedures appropriate to the dyeing operation concerned.
• Textile materials which may be treated by the process of our present invention includes those made of cotton, and other cellulosic materials, wool, linen, regenerated cellulose and a variety of other natural and artificial materials including nylons, polyester, polypropylene, esterified cellulosic materials such as acetate rayon, and acrylic fibres, and mixtures of natural and/or artificial materials.
• the textile materials may be in the form of Webs or sheets, either woven or non-woven as may be desired.
• a process for the production of a woven textile material consisting essentially of applying to the textile material, either prior to or during weaving thereof, a textile assistant chosen from the group which is soluble in a halogenated hydrocarbon solvent, weaving the textile, immersing the Woven textile in a halogenated hydrocarbon solvent which dissolves and removes the said textile assistant from said woven textile and removing any halogenated hydrocarbon solvent adhering to said woven textile by contacting the woven textile with hot water or steam.
