DE855936C - Process for hardening artificial intestines and similar structures made from skin substance by processing fiber masses - Google Patents

Description

Method of hardening artificial casings and the like by processing from fiber masses made from skin substance structures made from animal, fibrous materials, such as meat or skin, need to be made with it they are durable and, above all, waterproof, a subsequent tanning process. For one such tanning is found in gaseous or vaporous preservatives as well as treatments with liquid wood smoke condensate application. To ensure proper hardening of the entire Ensure the surface, especially to avoid under-hardening or over-hardening, it has been suggested to carry out repeated tanning and between the to switch on drying processes for individual tanning treatments. On the other hand, because of this under certain circumstances an excessive attack by the tanning agent was to be feared, has been considered necessary after further proposals, only with diluted ones Tanning agents, namely to work with solutions for which one has certain values, e.g. B. has set certain pH values and a certain iodine number.

Some of these procedures are cumbersome and some are conditional very precise operational monitoring and only feed under these conditions impeccable results.

It has now been found that tanning is much easier to achieve can, through which above all not only a uniform tanning of the skin structure is achieved is, but this is also perfectly tanned and not only superficially tanned when you use fabrics as they are used or suitable for tanning their total amount required or at least one, preferably to a large extent already for the production of artificial casings used fiber mass before its deformation, z. B. deformation caused by ring nozzles, adds. It is particularly advantageous to use this for such masses which have a high dry matter content, e.g. B. such a dry matter of about 25 ° a, exhibit.

This saves the previously necessary moistening and thus a or repeated drying and achieves that besides the faster and more thoroughgoing Tanning the fiber is significantly less attacked and the extent of the tanning can be precisely adjusted.

If desired, the finished artificial casing can also be made in usual way, for example when it solidifies in the inflated state Leaving the shaping nozzle with a tanning agent or with other post-treatment agents post-treatment, but usually only very slight tanning effects are sufficient for this. The hardened casings and the like are made before they are deformed with tanning agents The masses provided have a particularly uniform and excellent quality and durability.
