Description
Известен способ получени искусственных коллагеновых волокон посредством формовани пластифицированного пр дильного раствора коллагена, содержащего альдегид, в коагулирующую ванну.A method of producing artificial collagen fibers is known by molding a plasticized dope of collagen containing aldehyde into a coagulating bath.
Дл предупреждени слипани , повышени эластичности волокна при формовании и упрощени процесса выт гивани предложено в коагулирующую ванну добавл ть малеиновую кислоту.To prevent agglutination, increase the elasticity of the fiber during molding, and simplify the drawing process, it has been proposed to add maleic acid to the coagulating bath.
Пример 1. Очищенные и измельченные до размеров 2X2 см коллагеносодержащие отходы подвергают 24-48 час обработке 10%-ным NaOH в насыщенном растворе NagSO,. Затем нромывают проточной водой и раствор ют в 1 М растворе уксусной кислоты, содержащем 1% формальдегида и 0,5% дибутилфталата от веса белка. Полученный 2%-ный раствор продавливалс через фильеру , имеющую 15 отверстий с диаметром 0,1 мм, в осадительную ванну, содержащуюExample 1. Collagen-containing waste cleaned and crushed to a size of 2X2 cm is subjected to 24-48 hours treatment with 10% NaOH in a saturated solution of NagSO ,. Then it is sprayed with running water and dissolved in a 1 M solution of acetic acid containing 1% formaldehyde and 0.5% dibutyl phthalate based on the weight of the protein. The resulting 2% solution was forced through a spinneret having 15 holes with a diameter of 0.1 mm into a precipitation bath containing
ацетон и добавки малеиновой кислоты в количестве 2 г/л. Полученные волокна имеют более высокую температуру сваривани , что обеспечивает удлинение сроков рассасывани . Пример 2. Раствор коллагена получают так же, как и в примере 1, но все процессы ведут при 35°С. Концентраци пр дильного ра створа равна 10%.acetone and maleic acid supplements in the amount of 2 g / l. The obtained fibers have a higher temperature of welding, which provides for the lengthening of the terms of resorption. Example 2. A solution of collagen receive the same as in example 1, but all processes are carried out at 35 ° C. The concentration of the spinning solution is 10%.
