Изобретение отпоситс к кожевенной промышленности , в частности к технологии проведени последубильных процессов.The invention relates to the leather industry, in particular, to the technology of post-batch processes.
Известен способ обработки кожи, заключающийс в одновременном наполнении ее и жировании с использованием аминосмолы, например продукта карбампдальдегидиой ко}1денсации .A method of treating skin is known, consisting in simultaneously filling it and fattening it with the use of amino resin, for example, the product of carmpaldaldehyde codensation.
Предлагаемый способ позвол ет получить отбеливающий эффект, придающий коже белизну и светостойкость.The proposed method allows to obtain a whitening effect, giving the skin whiteness and light resistance.
Это достигаетс за счет того, что в качестве аминосмолы используетс модифицированна жирующими материалами аминосмола при температуре обработки 20-60°С и рН 4-4,5.This is achieved due to the fact that, as the amino resin, the modified amino fat resin is used at a treatment temperature of 20-60 ° C and a pH of 4-4.5.
Жирующа аминосмола представл ет собой продукт конденсации меламина, мочевины или дициадианмида с формальдегидом н жирующими материалами, например синтетическим жиром , синтетической жирной кислотой, ализариновым маслом и т. д.The fatty amino resin is a condensation product of melamine, urea, or dicyadanimide with formaldehyde and fatty materials, such as synthetic fat, synthetic fatty acid, alizarin oil, etc.
Все процессы, включа дубление и стрижку, провод т по типовой методике выработки хромовых кож. Затем обрабатывают полуфабрикат меламинформальдегидной смолой, модифицированной синтетической жирной кислотой .All processes, including tanning and shearing, are carried out according to a standard method for producing chrome leather. Then the semi-finished product is treated with melamine-formaldehyde resin modified with synthetic fatty acid.
Температура сбраоотки 20-60 С; ж. к. 0,4--2,0; рИ раствора 4-4,5; расход смолы 1 -10% (в пересчете на сухой остаток) от строганого веса; врем 30-90 мин.Temperature of the discharge is 20-60 ° C; g. q. 0.4-2-2; rI solution 4-4,5; resin consumption 1 -10% (in terms of dry residue) of the planed weight; time 30-90 minutes
Предмет изобретени Subject invention
Способ обработки кожи, заключающийс в одновременном наполнении ее и жировании с использованием аминосмолы, отличающийс тем, что, с целью получени отбеливающего эффекта, в качестве аминосмолы используют модифицированную жирующими материалами аминосмолу, при этом обработку ведут при температуре 20-60° С и рИ 4,5.The method of treating the skin, which consists in simultaneously filling it and fattening it with the use of amino resin, characterized in that, in order to obtain a whitening effect, the amino resin modified with fatting materials is used as the amino resin, the treatment is carried out at a temperature of 20-60 ° C and pI 4 five.
