Description

Изобретение относитс ккрасительноотделочному производству, в частности к способам крашени текстильных материалов .The invention relates to painting and decorating production, in particular to methods for dyeing textile materials.

Известен способ крашени текстильных материалов пропиткой красильным раствором с последующей тепловой обработкой при температуре на 30-70°G выше температуры разм гчени материала в течение 2-18 с при суммарном конвективном и Лучистом тепловом потоке на материал 3 ТО- -Ю ккал/м -ч.There is a method of dyeing textile materials by impregnation with a dye solution followed by heat treatment at a temperature of 30-70 ° G above the softening temperature of the material for 2-18 s with a total convective and radiant heat flux of material 3 TO-Kcal / m -h .

Недостатком известного способа вл етс недостаточна интенсивность процесса (врем фиксации).A disadvantage of the known method is the insufficient intensity of the process (fixation time).

Целью изобретени вл етс интенсификаци процесса.The aim of the invention is to intensify the process.

Поставленна цель достигаетс тем, что в известном способе крашени текстильных материалов пропиткой раствором красител с последующей тепловой обра боткой тепловую обработку провод т между пористыми прижимными поверхност ми с температурой 220-230°С с подведением на них электрического тока переменного напр жени 3-10 В и частотой 4-12 Гц.This goal is achieved by the fact that in the known method of dyeing textile materials by impregnation with a dye solution followed by heat treatment, heat treatment is carried out between porous pressing surfaces with a temperature of 220-230 ° C with applying an electric current of 3-10 V to them and frequency of 4-12 Hz.

Пример 1. Текстильный материал триацетат Нашлайте - пропитывают раствором дисперсного красител , а затем ткань с красителем помещают между пористыми прижимными поверхност ми, нагретыми до температуры 220°С. На пластины подают электрический ток напр жением 3 ВExample 1. The textile material is triacetate. Finding is impregnated with a dispersed dye solution, and then the fabric with the dye is placed between porous pressing surfaces heated to a temperature of 220 ° C. An electric current of 3 V is applied to the plates.

2. Textile material is natural silk - impregnated with an acid dye solution, and then the fabric with the dye is placed between porous pressing surfaces heated to a temperature of 220 ° C. An electric current of 4 V and a frequency of 6 Hz is supplied to the plates. The dye is fixed in 2 seconds. The amount of fixed dye is 74%, L / M

3. Textile material cotton fabric - impregnated with a solution of active dye, and then the fabric with the dye is placed between porous pressure surfaces, heated to a temperature. An electric current of 10 V and a frequency of 12 Hz is supplied to the plates. Fixation takes 2 seconds. The amount of fixed dye is 92%.

The use of this method in the processing of text of nogr material helps to intensify the process (fixing time 1-2 s), increase the degree of fixation of the dye on the material from triacetate fibers from 75 to 83%, from polyester from 88 to 92%, for natural silk from 72 to 74 % for cotton from 89 to 92%.
