Description

Предлагаетс  способ подготовки ме/гкпх кож, например козлины, к дублению, по которому nocjie намазки и сгонки uiepcTH голье промывают, мездр т, обезволивают и обрабатывают протео.читическим ферментом при рН выше 7,A method is proposed for preparing me / gkph skins, for example goats, for tanning, by which the nocjie of spreads and descaler pill are washed, cleaned, allowed and treated with a proteometic enzyme at a pH above 7,

По предложенному способу после обычных операций, включающих сгонку шерсти, вместо золки на сернистом натре голье подвергают прол1ывке в баркасе нри температуре 20° и жидкостном коэффициенте 1:2,5 и затем в барабане при жидкостном коэффициенте 1:1,5 в течение 1 Va-2 час. При промывке шелочь, наход ща с  внутри голь , переходит в раствор и способствует ускорению распространени  нажора по всей толщине голь .According to the proposed method, after the usual operations involving the cutting of wool, instead of zolka on sulphurous sodium, the aspirin is subjected to proliferation in a long boat at a temperature of 20 ° and a liquid ratio of 1: 2.5 and then in a drum at a liquid ratio of 1: 1.5 for 1 Va- 2 hours During the washing, the bile, which is inside the mole, goes into solution and helps to accelerate the spread of fats throughout the entire thickness of the mole.

Дальнейша  работа по мездрению на лкчшнне производитс  обычным пор дком. Последующее обеззо,1нвание производ т на свежей воде нри температуре 30° сернокислым аммонием с доведением рН до 8,5,Further work on meting on the computer is done in the usual way. Subsequent disinfection, 1nvve produced in fresh water at a temperature of 30 ° ammonium sulfate with bringing the pH to 8.5,

После повышени  температуры обеззоли.вающей ванны до 38° в последнюю ввод т протеолитически действующий фермент активностью в 1000 казеиновых единиц в количестве 1% от веса голь . Ферментативна  обработка нродолжаетс  от 6 лТ,о 9 час нри температуре ванны н 37-38° и щелочности, не выход ихей за пределы рН 8,2-8,7 (слабое с.ч рашивание на фенолфталеин).After increasing the temperature of the desalting bath to 38 °, the proteolytic activity of 1000 casein units is introduced into the latter in an amount of 1% by weight a mole. Enzymatic treatment is continued from 6 lT, about 9 hours at a bath temperature of 37-38 ° C and alkalinity, not exceeding the limits of pH 8.2 to 8.7 (weak total saturation of phenolphthalein).

После ферментативной обработки полуфабрикат подвергают чистке лица, пикеливанию и последующим операци м по обычной методике.After the enzymatic treatment, the semi-finished product is subjected to face cleaning, pickling and subsequent operations in the usual manner.

Предмет п з о б р е т е н и  Subject matter

Способ подготовки мелких кож к дублению, отличающийс  тем, что носле намазки и сгонки щерсти голье промывают, мездр т, обеззоливают и подвергают обработке протеолитическим ферментом при рН выше 7,The method of preparing small leathers for tanning, characterized in that, when spreading and combing the hair, the hide is washed, cleaned, dehed and treated with a proteolytic enzyme at a pH above 7,
