    • A method for modifying fibers of a fabric which comprises applying an effective amount of an aqueous salt solution to the fabric to sufficiently wet all of the fibers of the fabric with the salt solution, removing excess solution from the fabric, contacting the wetted fabric with a pair of electrodes through which a sufficient electromotoric force is aplied to the salt solution in the fabric to generate an acidic and/or caustic solution at or near the surface of the fabric. Thereafter, the fabric is heated for a period of time and at a temperature effective to produce a chemical reaction between the fibers wet with the acidic and/or caustic constituent resulting from the above electrolysis of the aqueous salt solution. After the desired degree of fiber modification has occurred, the chemical reaction is quenched and the resulting product recovered. The particular salt constituent employed in the aqueous salt solution will be dependent upon whether the desired fiber modifying agent is an acid, base, or both.
    • 一种用于改变织物纤维的方法,其包括将有效量的盐水溶液施加到织物上以用盐溶液充分湿润织物的所有纤维,从织物上除去多余的溶液,使湿织物与 一对电极,通过该电极将足够的电动力施加到织物中的盐溶液中,以在织物的表面处或附近产生酸性和/或苛性溶液。 此后,织物被加热一段时间,并且在有效地在由盐水溶液的上述电解产生的酸性和/或苛性成分湿润的纤维之间产生化学反应的温度。 在发生所需的纤维改性程度之后,化学反应骤冷,并将所得产物回收。 在盐水溶液中使用的具体盐成分将取决于所需的纤维改性剂是酸,碱还是两者。

    • Bright greenish yellow dyes of excellent color value prepared by coupling a lower alkyl anthranilate into 1-phenyl-3-carbalkoxy-5-pyrazolone and having the formula: ##STR1## WHERE R and R.sub.1 are independently lower alkyl; X is hydrogen, halogen, nitro, hydroxy, lower alkyl or lower alkoxy; Y is hydrogen, halogen, lower alkyl or nitro and a and b are integers of 1-2. This class of azo dyes, when appropriately dispersed, produces dyeings on aromatic polyester fabrics with excellent substantivity, outstanding sublimation fastness and good fastness to light. The dyes are applied to polyester, such as polyethyleneterephthalate, by carrier dyeing, pressure dyeing and thermofixation methods.
    • 通过将邻氨基苯甲酸低级烷基酯偶联到1-苯基-3-烷氧基-5-吡唑啉酮中并具有下式制备的具有优异颜色值的明亮的绿黄色染料:其中R和R 1独立地为低级烷基; X是氢,卤素,硝基,羟基,低级烷基或低级烷氧基; Y是氢,卤素,低级烷基或硝基,a和b是1-2的整数。 这种偶氮染料在适当分散时,在芳香族聚酯织物上产生染色,具有优异的亲和性,优异的升华牢度和良好的耐光牢度。 通过载体染色,压力染色和热固定方法将染料施用于聚酯,如聚对苯二甲酸乙二醇酯。

    • Acylamino quinophthalone compounds which are free from sulfonic acid groups and correspond to the formula ##STR1## in which R.sub.1 and R.sub.2 are hydrogen, halogen, acylamino or lower alkoxy with the proviso that one of the residues R.sub.1 and R.sub.2 denotes acylamino while the other residue stands for hydrogen, halogen or a lower alkoxy; R.sub.3 is hydrogen, halogen or a lower alkoxy; X is a substituent; and n is a number from 0 to 3; are disclosed. The compounds useful as dyestuffs for hydrophobic fiber materials, e.g. polyester, are prepared by reacting an acylamino phthalic acid, the anhydride thereof, or mixtures of acylamino phthalic acids or the anhydrides thereof with a 3-hydroxy-quinalide.
