Description

Изобретение относитс к текстильному отделочному производству и может быть использовано дл облагораживани текстильного материала при его мерсеризации. .The invention relates to a textile finishing industry and can be used to enrich a textile material during its mercerization. .

Известен способ отделки текстильного материала путем его мерсернзации в растворе щелочи с последующей промлвкой в жидкостной ванне и упариванием отработанного раствора щелочи с последующей подачей его на мерсеризацию fl.There is a method of finishing a textile material by mersernization in an alkali solution, followed by flushing in a liquid bath and evaporating the spent alkali solution, followed by feeding it to the mercerization fl.

Однако известный способ требует значительного расхода воды дл промывки материала, а дл подогрева воды обычно расходуетс значительное количество пара.However, the known method requires a significant consumption of water for washing the material, and a significant amount of steam is usually used for heating water.

Цель изобретени - уменьшение энергозатрат.The purpose of the invention is to reduce energy consumption.

ПоставленнёШ цель достигаетс тем, что в способе отделки текстильного материала путем его мерсеризации, в растворе щелочи с последующими промывкой в жидкостной ванне и упариванием отработанного, раствора- щелочи с последуквдей подачей его на мерсеризацию , полученный при упаривании раствора щелочи пар подают в конденсатор , а полученный конденсат направл ют в промывную жидкостную ванну.The goal is achieved by the fact that in the method of finishing textile material by mercerizing it, in an alkali solution, followed by washing in a liquid bath and evaporating the spent, alkali solution followed by feeding it to the mercerization, the vaporized solution of the alkali solution is fed to a condenser, and the resulting the condensate is directed to a wash liquid bath.

Отработанную промывную жидкость направл ют в конденсатор дл охлаждени конденсируемого пара с последующей ее подачей дл упаривани .The spent wash liquid is sent to a condenser to cool the condensable vapor, followed by its supply for evaporation.

Причем перед подачей конденсата в промыйную жидкостную ванну, его очищают и нейтрализуют.Moreover, before supplying the condensate to the washing liquid bath, it is cleaned and neutralized.

На чертеже представлена технологическа схема реализации предлагаемого The drawing shows the technological scheme of the proposed

10 способа.10 ways.

Схема содержит концентратор 1 щелока , мерсеризационный агрегат 2, систему .3 очистки раствора,конденсатор 4 пара, установку 5 очистки и нейтрализации конденсата, установку приготовлени свежего щелока.The scheme contains a liquor concentrator 1, a mercerization unit 2, a solution purification system. 3, a steam condenser 4, a condensate purification and neutralization unit 5, a fresh liquor preparation installation.

.Способ осуществл етс следующим образом.The method is carried out as follows.

Материал подаетс на обработку в 20 мерсеризационный агрегат 2, где осуществл ютс процессы пропитки ее ще . локом, отжима и промлвки. Облагороженный материал, например ткань, затем направл етс на последующие тех25 нологические операции. The material is fed to a treatment in a 20 mercerization unit 2, where its impregnation processes are carried out. lock, wringing and blasting. The refined material, for example fabric, is then sent to subsequent technological operations.

Claims

The evaporated liquor solution is fed to the mercerization unit 2 from the liquor concentrator 1. Its concentration (BC) depends on the type and property 30 of the material. Usually, vts 180-300 g / l. The liquor pressed out of the material after the system 3 purification of the solution is returned to evaporation or is used for other technological purposes, for example for decoction of fabrics. In the latter case, a fresh solution from plant 6 is added to the mercerization with the preparation of fresh lye. The steam from the hub 1 enters the steam condenser 4, there it condenses and is sent to wash the fabric in the mercerization unit 2, where the stripping process takes place during a C-EO C. A purification unit 5 is provided for cleaning and neutralizing the condensate. From the metering unit 2, the washing liquid (weak liquor) with a concentration (B (J) of 40-50 g / l is returned to the condenser 1, where its concentration is adjusted to the required 80-300 g / l. To use steam heat to the condenser 4, weak liquor before concentration.To ensure normal operation of condenser 4, a temperature pressure of 1015 ° C is required. Therefore, weak liquor is heated to a temperature below the washing temperature by 10-15 ° C, i.e. to 70-75 s, and the concentration is carried out at a temperature corresponding to rinsing. Thus, and using steam condensate as a stripping liquid eliminates the consumption of hot water for washing in an amount of 35 m3 / h per ton of material, and the steam consumption in an amount of 5-6 tons / h. When heating weak liquor before concentrating, the consumption of heating steam decreases CHP for evaporation. Claim 1. The method of finishing a textile material by mercerizing it in an alkali solution, followed by sieving in a liquid bath and evaporating the spent alkali solution, followed by feeding it to mercerization, differing in That, for the purpose umenyieni energy obtained by steam evaporation of the alkaline solution fed to the condenser and the resulting condensate is fed to the liquid bath prokyvnuyu ..

2. Method nofi.l, that is, with the fact that the spent washing liquid is directed to a condenser for cooling the condensable vapor and then feeding it to evaporation.

3. Method up to p. 1, oh; L and h and y and the fact that before the supply of condensate in the washing liquid bath it is strengthened and neutralized.
