Description

Предметом насто щего изобретени   вл етс  способ получени  нерастворимых лаков основных красителей, в субстанции и на волокнах, путем осаждени  основных красок продуктом конденсации бэтанафтола с формальдегидом. Предлагаемый способ имеет, по мнению автора, перед другими, уже известными способами следующие преимущества: он дает стойкий на воздухе и комбининируюндийс  с дназосоединени ми продукт , закрепл ющий основные красители прочнее других, напр., дубильносурьм ной соли, а присутствие солей хрома, цинка и т. п. повыщает эту прочность.The subject of the present invention is a process for the production of insoluble base paints, in substance and on fibers, by precipitating base paints with a condensation product of beta-naphthol with formaldehyde. The proposed method, according to the author, has the following advantages over other, already known methods: it gives a product that is resistant to air and combines with bottoms, fixing the basic dyes stronger than others, for example, tanning salt, and the presence of chromium, zinc and t. n. increases this strength.

Дл  получени  нерастворимых лаков основных красителей в субстанции, автор предлагает прибавл ть к раствору основHOio красител  какой-нибудь субстрат, напр., каолин и полученную смесь осаждать Н1елочным раствором продукта конденсации бэтанафтола с формальдегидом , осадок декантировать, а потом промывать на фильтре.To obtain the insoluble varnishes of the basic dyes in the substance, the author proposes to add some substrate to the base solution of the dye, for example, kaolin and the resulting mixture to precipitate with a metallic solution of the condensation product of beta-naphthol with formaldehyde, decant the precipitate, and then wash the filter.

Дл  получени  и закреплени  основных красителей на ткани по способу кра1нени , изобретатель рекомендуетTo obtain and fix the basic dyes on the fabric according to the dyeing method, the inventor recommends

нлюсовать волокнист1 1й материал в Hieлочном растворе продукта конденсацпп бэтанафтола с формальдегидом, затем подвергнуть таковой кисловке в слабом растворе сол ной кислоты и, наконец, красить в растворе основной краски. Промывка и сушка производитс  обыкновенным способом.Note the fibrous material of the 1st material in the helical solution of the condensate product of beta-naphthol with formaldehyde, then subject it to a weak acid solution in a weak solution of hydrochloric acid and, finally, paint in the solution of the base paint. Washing and drying is done in an ordinary way.

Дл  закреплени  основных красителей на ткани по способу набивки, изобретатель предлагает плюсовать ткань в Hieлочном растворе продукта конденсации бэтанафтола с формальдегидом, после npocynjKH печатать основным красителем с прибавкой глицерина и загусткп и, наконец, запарить па несколько минут в зрельне, где, по мнению автора, под вли нием пара, происходит образование нерастворимых лаков и закрепление их на ткани одним пропуском.To fix the basic dyes on the fabric according to the stuffing method, the inventor proposes to add fabric in the Heel solute solution of the condensation product of beta-naphthol with formaldehyde, after npocynjKH print the main dye with the addition of glycerin and thicken and finally steam a few minutes in the middle where under the influence of steam, the formation of insoluble varnishes occurs and they are fixed on the fabric with one pass.

Далее установлено автором, что если при получении нерастворимых лаков путем осаждени  основных красителей продуктом конденсации бэтанафтола с формальдегидом примен ть соли некоторых металлов, напр., хрома или цинка, получаютс  еще более прочные соединени .Further, it has been established by the author that if, when producing insoluble varnishes by precipitating basic dyes with the condensation product of beta-naphthol with formaldehyde, salts of certain metals, for example chromium or zinc, are used, even more durable compounds are obtained.
